OpenRAN是什么
OpenRAN是什么这两天，⼏乎全球电信业都聚焦于沃达丰的⼀纸公告。
这家在全球25个国家拥有并运营通信⽹络的跨国电信巨头，宣布了⼀件⼤事——启动OpenRAN试验。
推动部署Open RAN将使沃达丰和电信⾏业能够引⼊⼀批新的2G、3G、4G和5G技术供应商，可望增加电信设备供应商的数量，从⽽改善供应链的弹性。
更值得关注的是，业界头⼀次将此次OpenRAN试验称为“规模试验”。
此OpenRAN并⾮是由中国移动、AT&T、德国电信等运营商于2018年发起的O-RAN联盟，但两者⾮常相似。
OpenRAN是TIP联盟的其中⼀个计划，⾃2017年以来，沃达丰⼀直在OpenRAN计划中扮演推动者⾓⾊，以推动该技术成熟。
TIP，即Telecom Infra Project，电信基础设施项⽬，于2016年由Facebook发起，旨在基于开源软/硬件部署电信⽹络。
TIP联盟⽬前已有超过500家成员，包括运营商、设备商、芯⽚商、IT商和系统集成商，其中，沃达丰、西班⽛电信、德国电信、英国电信、SK电信、诺基亚、英特尔等都是主要成员。
TIP已发布了三⼤项⽬组：接⼊、回传和核⼼&管理，⼏乎涵盖了整个通信⽹络领域。
▲TIP⽆线接⼊项⽬组OpenRAN是TIP⽆线接⼊项⽬组中的其中⼀个计划，Vodafone是OpenRAN计划的主持者，该计划通过软硬件解耦和接⼝开放化，打破传统电信设备软硬件⼀体化、接⼝⾼度集成化的“⿊盒⼦”式架构，使运营商可采⽤来⾃不同供应商的软件、通⽤硬件来实现模块化混合组⽹，从⽽避免被传统设备供应商锁定，降低成本，提升议价能⼒。
⽐如，传统基站的BBU和RRU来⾃同⼀家⼚家，⽽Open RAN让运营商可以从A供应商采购软件，从B供应商采购COTS服务器，再从不同的供应商采购RRH设备，来实现模块化组站。
⽬前，TIP联盟中已脱颖⽽出三⼤OpenRAN供应商，分别是三家美国公司：Altiostar、Mavenir和Parallel Wireless。

The FP-TPX3A may be rack or surface mounted with optional FLAT-PAK series accessories. The FP-TPX3A gives you the advantages of a quality audio mixer with the added convenience of remote control!The FP-TPX3A is the ideal choice where a user-accessible mixer must control the volume of multiple sources in a zone. RDL Format-A twisted pair audio senders connect directly to the mixer, allowing each user input to be balanced or unbalanced, mic or line level. FP-TPX3A outputs are provided in balanced and unbalanced formats. Two unbalanced outputs are available to feed the mono mixer output to a stereo amplifier input. Remote control of the mixer allows audio signals to be kept at a single equipment location. Audio is mixed by VCA circuits that are adjusted by control signals from the remote control.Two Format-A jacks are provided for signal inputs. If the Format-A senders are daisy-chained, only one of the input jacks is used. The other input jack may be used to receive another Format-A sender, or may be used to loop the received Format-A signals out to additional Format-A mixers or receivers. The FP-TPX3A provides power to all connected active senders. The FP-TPX3A is designed to mix the three Format-A audio signals from pairs A, B and C. A front-panel switch allows the PAIR C mixer input to be fed either from the twisted pair C input signal or from a local input. A detachable terminal block is provided to connect a local paging or music source to the LOCAL INPUT . Note: Pair C signals are passed through both Format-A input jacks even if the mixer is set to use a local source instead of the PAIR C twisted pair source.Format-A senders are available in active and passive models. Passive Format-A models with unbalanced input jacks send a lower signal level to the mixer than is sent by active senders or by passive senders with balanced inputs. Each INPUT GAIN control is calibrated to be adjusted clockwise for an unbalanced passive sender; counter-clockwise for an active sender or passive sender with a balanced input. A standard RDL dual-LED VU meter provides visual indication of the output level from the mixer. Each input channel operates at unity gain when the corresponding remote control is adjusted to maximum. This assures ample headroom at all normal operating levels. The mixer output is mono. The output is available on a single balanced detachable terminal block or on two unbalanced RCA jacks intended to connect directly to the stereo input of a power amplifier.The AUDIO LED illuminates whenever audio is present at the output of the mixer, defined as greater than 35 dB below +4 dBu. This threshold triggers the AUDIO DETECT OUTPUTS . Two open collectors are provided on a detachable terminal block. One of these terminals switches low when audio is present, and may be used to switch amplifiers or other system components on. The other terminal is pulled low when audio is not present. It is intended for muting the digital carrier of power amplifiers equipped for remote muting. Either of these terminals may be used to trigger a variety of other RDL modules or OEM equipment. The use of these terminals to shut down unused equipment can produce effective system energy and cost savings. These control terminals normally remain triggered for 10 minutes after audio is absent. The delay can be increased to 20 minutes using a ground jumper on the terminal block.The mixer levels are set by RDL remote controls that connect directly to the FP-TPX3 through an RJ45 jack using standard twisted pair cable. The control ports on the mixer and remote controls are color-coded light blue to distinguish them from standard Format-A jacks. The mixer provides power to the remote control. Either a two or three channel remote control may be used. If remote mixing of only two channels is needed, a two channel remote may be used. Pair C becomes the input channel that is not remotely controlled. The PAIR C /LOCAL INPUT can be left active at unity gain, typically for a paging source, or may be disabled by a switch set during installation. If the cable connected to the remote control becomes disconnected, the mixer output mutes.RDL ∙ 659 6th St. ∙ Prescott, AZ., USA 86301 ∙ (928) 443-9391 ∙ FAX (928) 443-9392 ∙ TYPICAL APPLICATIONS:► Meeting Rooms ► Boardrooms ► Classrooms► Restaurant or Residential Patios ► Retail Stores ASSOCIATED REMOTE CONTROL EXAMPLES: ► D-RC2 and DS-RC2 Two-channel remote controls ► D-RC2M and DS-RC2M Two-channel remote controls with muting► D-RC3 and DS-RC3 Three-channel remote controls ► D-RC3M and DS-RC3M Three-channel remote controls with mutingFLAT-PAK ™SERIESModel FP-TPX3AFormat-A Twisted Pair Remote Controlled MixerTYPICAL PERFORMANCEInputs (3): RDL FORMAT-A; Balanced line levelInput Connections: RJ45 (FORMAT-A); Detachable Terminal Block (Pair C) Outputs (3): 150 Ω balanced; 1 k Ω unbalanced (2)Output Connections: Detachable Terminal Block (balanced); RCA Phono Jacks (unbalanced) Output Level: +4 dBu balanced, -10 dBV unbalanced Frequency Response: 20 Hz to 20 kHz (+/- 0.25 dB)THD+N: < 0.05% (20 Hz to 20 kHz); <0.02% (1 kHz)Noise below +4 dBu: < -100 dB (all channels off); <-75 dB (any channel on); <-70 dB (all channels on) Headroom above +4 dBu: > 18 dBCMRR: > 80 dB (50 Hz to 150 Hz)VCA attenuation: >90 dB (each input, remote control volume off)Indicators (3): Dual-LED VU meter (2); Audio present (threshold = 35 dB below +4 dBu output) Power Connections (3): Terminal block; dc power jack (2)Power Requirement: 24 Vdc @ 120 mA plus connected FORMAT-A sender currents Overall Dimensions: Height: 1.42 in.3.61 cm Width: 3.25 in. 8.26 cmLength: 8.14 in. 20.68 cmInstallation/OperationDeclaration of Conformity available from .

OpenText ALM Quality Center产品介绍说明书
ALM/Quality CenterT o innovate your business through software, ensuring application quality is more critical than ever. This doesn’t mean achieving quality is easy, however. OpenT ext ALM/Quality Center serves as the single pane of glass for software quality management and enables rigorous, auditable lifecycle processes.Product HighlightsEnterprises are turning from software con-sumers to producers and creating many new applications to innovate business digitally. T o succeed in a competitive market, ensuring application quality is essential. Quality affects your digital business in several ways: brand reputation, business growth, competitive ad-vantage, and customer experience. To give a few examples, users will quickly abandon a buggy mobile app, and your business growth will suffer. Launching a poor-quality business web site will lose customer trust and likely cause compliance issues. Without quality, any great initiative won’t succeed. However, achiev-ing quality goals is easier said than done. The challenges of inter-team alignment, complex-ity, visibility, and regulatory compliance make delivering high-quality software difficult.OpenT ext™ Application Lifecycle Management (ALM)/Quality Center empowers you to meet these challenges. It helps you achieve high efficiency in testing and manage quality with a requirements-driven, risk-based approach, align people with processes, mitigate appli-cation complexities, automate manual tasks, and establish end-to-end traceability. Gaining a complete view across all releases and proj-ects grants you insights that help informed decisions. Multiple deployment options, open integrations with common tools, and strong data control make ALM/Quality Center ideal for ensuring compliance and adapting to changes.Key FeaturesT rack and Consolidate T esting EffortsA lack of coordination and visibility leads to unsynchronized teams and delayed releases. Plus the absence of centralized testing efforts across the business increases cost and testing time. Y ou need a way to:■ Visualize and manage quality and testingprocesses.■ Drive cross-organization collaborationamong analysts, QA, and developers.ALM/Quality Center saves a large percentageof testing effort with automatic test execution and test result collection, reusable assets, and a shared library. It takes little effort to create reports and analyze data. ALM/Quality Center consolidates information from various sources and generates graphs and a dashboard. Using business process models and business pro-cess testing (BPT), you can see clearly if teams are correctly implementing business require-ments. Leverage the traceability matrix to change and test the right part of your applica-tion. The risk-based quality management fea-ture helps you focus on the most critical parts. These capabilities enable you to optimize lim-ited resources.The OpenT ext™ UFT One integration further boosts efficiency—granting automatic test cre -ation from requirements and converting manual tests to automated ones. Y ou will also gain a rich set of choices for testing tools, OpenT ext™ or 3rd-party, open-source or proprietary.“ALM/Quality Center tracks and manages the entire testing process and defect management for us, and we introduced automation for 72 percent of all test cases.”JOSÉ JIMÉNEZSAP Delivery Center T est Management Lead, IT Global Development Center Japan T obacco InternationalData SheetData SheetALM/Quality CenterEnable End-to-End T raceabilityEnterprise applications contain complex rela-tionships among existing features, new require-ments, and their associated artifacts. Without a way to keep track of these relationships, any change to the application requires a significant amount of work. This challenge makes measur-ing application quality more difficult because you have to identify what code to change and which tests to perform.ALM/Quality Center provides comprehensive traceability to manage these relationships. Y ou can use business process models to trace rela-tionships between different requirements, and traceability matrix to trace from any require-ment to its tests, defects, releases, and service desk tickets—and vice versa. These build end-to-end traceability throughout the application lifecycle, helping verify that requirements are met and identify the impact of changes.Achieve T ransparency with Analytics and ReportingT esting doesn’t equal quality. Y ou need a holis-tic view of all application components across all releases. ALM/Quality Center drills down into individual projects and offers insights that as -sist your decisions.ALM/Quality Center provides intuitive experi-ences to create holistic reports, such as:■ Aggregated project status metrics.■ Application quality metrics.■ Requirements coverage.■ Defect trends.■ Health reports for both an enterpriserelease (cross-project) and individual project view.■ Executive dashboard of KPIs.■ Graphs for discovering correlations,or anomalies.Its analytics and graphing capabilities simplify status tracking, provide real-time insight, and reveal correlations and trends from historicaland current data.Figure 1. Example of ALM/Quality Center reportingBesides built-in graphs, ALM/Quality Center features a graph wizard that helps users cre-ate custom reports and charts—without the need of scripting or query language expertise.Automate Workflow and Standardize ProcessesFrom planning through delivery, creating high-quality applications requires governance across teams and releases. Even the strongest development teams suffer quality setbacks and timeline slippage if inter-team dependen-cies are lost.ALM/Quality Center provides a sound founda-tion for alignment by facilitating:■ A common release cadence ■ Advanced dependency mapping ■ Automated workflows ■ T emplates ■ Library sharing■ Cross-project customizationYou maintain a consistent way of working across your organization and synchronizeall stakeholders with a unified data reposi-tory. The workflow controls change manage -ment, minimizing the risks of side-effects and human errors.Adapt to Highly Regulated EnvironmentsManaging application development in a highly regulated environment can be time-consum-ing, labor-intensive, and costly—especially with paper-based or manual processes. Auditors execute audits throughout the application development lifecyle against regulations and guidelines, such as 21 CFR Part 11, GAMP5, SOX, HIPAA, and GDPR to ensure that organi-zations follow the right processes and proce-dures required. Periodically providing detailed evidence of compliance is not a trivial task.ALM/Quality Center helps you efficiently achieve compliance by enforcing processes, standards, and security. Creating audit reports is easy through end-to-end traceability, ver-sion control, baselines, automated audit trails, and detailed test results for each step. ALM/Quality Center secures sensitive product and project data with the right measures, such as:■ SSO authentication and API keyauthentication■ Role-based permissions ■ Encrypted communication■ Data hiding when creating reports or graphsThese capabilities facilitate a fully traceable and auditable validation process using ALM/Quality Center and a OpenT ext or a third-party e-signature or e-approval solution on top. Sign off ALM entities electronically after ev-ery human interaction, such as rejection and approval. Meanwhile, you can leverage out-of-the-box add-ins to accelerate the implemen-tation of compliance processes, including the GDPR Content Pack, e-Signature QuickStart Project, and SOX IT Assessment Accelerator.Moreover, the offline testing its QoT (Quality of Things) client enables on portable devices em-powers your users to perform tests in various places without ALM server connectivity, whilerecording test results and defects electronically.Figure 2. Sample defect workflow with ALM e-SignatureIntegrate across Y our Enterprise EcosystemIn today’s development ecosystem, it is criti-cal for enterprises to seamlessly integratevarious tools into a toolchain. Consolidating proper data from these tools into a central repository provides a complete and accurate picture of the lifecycle. You can then use this data to continuously improve. This process often involves integration at each stage of the application lifecycle.ALM/Quality Center continues adding capa-bilities that support the solutions you use to-day—and tomorrow. It integrates with a wide range of open-source and proprietary tools from OpenT ext and third-party, including:■ Portfolio management and requirementmanagement tools.■ Common Enterprise Agile Planning tools.■ T esting tools.■ Service management solutions.■ Collaborative software.In the testing tool category, besides UFT One, OpenT ext™ UFT Digital Lab, OpenT ext™ LoadRunner Professional and OpenText™ Fortify, ALM/Quality Center also supports many third-party automation tools and frameworks, such as JUnit, NUnit, Selen i um, Appium, JMeter, SonarQube, and even homegrown tools.Additionally, OpenText Connect provides a single integration hub for data synchronizationacross teams, projects, and locations. Best of all, it’s included with ALM/Quality Center.Facilitate Agile and DevOps T ransformationIf you are among the enterprises adopting Agile and DevOps practices, you know the trans-formation is gradual instead of overnight. You need a transition period where you can access both your traditional and Agile tools. Striking the right balance can make or break teams and projects during the process.ALM/Quality Center works with OpenText™ ALM Octane to make the transition smooth. While the two products are similar in their quality focus, ALM Octane aligns Agile and DevOps development with testing processes to improve the flow of work throughout the software delivery value stream. The T est Run Injection allows you to leverage existing assets in ALM/Quality Center while using ALM Octane as the central hub for management. In short, you transition at the pace you want.When you want to practice value stream management (VSM) to accelerate your Agile and DevOps initiatives, you have a smooth path to adopt our VSM platform—ValueEdge,which lets you leverage what you’ve investedFigure 3. ALM/Quality Center integrationsin ALM/Quality Center—data, testing assets and licenses.Adapt with an Open andSecure ArchitectureBeing able to respond flexibly to business needs helps your organization stay competi-tive. There are numerous considerations when choosing a solution that can adapt to potential changes in scale, processes, and integration. ALM/Quality Center facilitates a customizable, scalable approach for enterprises. You can tailor it to fit the needs and standards of your business and scale it to handle an increase in projects, users, and tests. In addition, it is highly extensible with its REST APIs, covering user and administrator operations.You also want to easily and securely manage access to sensitive lifecycle data while giving users a simplified way to manage logins. ALM/ Quality Center supports single sign-on (SSO), API key authentication and importing users from an LDAP directory to help you achieve it. It also offers security measures to protect data integrity from unauthorized access and manipulation, and manages users with differ-ent security clearances to work on the same project without exposing sensitive data. Flexible Deployment andLicensing OptionsNo two organizations are alike in how they want to consume or acquire their software. ALM/ Quality Center has flexible options for deploy-ment and licensing to suit any specific needs. Y ou can deploy your way to minimize infrastruc-ture maintenance and improve resilience.While on-premises deployment gives youcomplete control of both infrastructure and theALM server, it requires more effort to maintain.Business resiliency is mandatory and remotework has become normal.

It’s designed to work seamlessly with the Dialogue System for Unity.Note: Language models are not sentient. They are essentially just very advanced pattern matchers. Results may contain grammatical or factual errors, so review them carefully before using them.Language ModelsThe OpenAI API provides access to several language models and parameters. In the Dialogue System Addon, the UIs to specify language models and parameters look like this:Model: This dropdown allows you to choose a language model for content generation:Model DescriptionGPT_3_5_Turbo Best for most cases. Similar performance to Davinci at 10% of the price. GPT_3_5_Turbo_16K Same as GPT-3.5 Turbo but with 4x the context window for longer responses. GPT_4Newest, most powerful language model. Improves on GPT-3.5.GPT_4_32K GPT-4 with larger 32k context window that allows for very long responses. Davinci Powerful model but slow. Good at complex intent and cause & effect. Curie: Second most powerful model. Good at language translation.Babbage Second fastest model. Good at classification.Ada Smallest, fastest, and least expensive model, but results may be poor. Temperature: Specifies the amount of “randomness” to include in the content. A value of zero generates plain, straightforward responses. A value of one generates more unexpected or “creative” responses.Max Tokens: Specifies the maximum number of tokens to spend on a response. Lower numbers generate shorter responses; higher numbers can generate longer responses. OpenAI pricing is based on the number of tokens used, so you can use this slider to reduce expenses.ElevenLabs Speech SynthesisYou can use the API provided by ElevenLabs, a separate company from OpenAI that specializes in speech synthesis, to generate voiceover audio for your dialogue.ElevenLabs uses a separate API key. Any charges for using the API are applied to your API key account. (See Pricing.)You can use the addon’s ElevenLabs features to generate audio at design time and at runtime.Dialogue SmithYou can also use the API provided by Dialogue Smith, a separate company from OpenAI that specializes in advanced dialogue generation, to fill in dialogue for branching conversation trees. Dialogue Smith uses a separate API key. Any charges for using the API are applied to your API key account.Welcome WindowUse menu item Tools → Pixel Crushers →Dialogue System → Addon for OpenAI → Welcome Window to open the Welcome window.The Addon for OpenAI will use your OpenAI API key, which you can create on OpenAI’s website. You are responsible for any usage charges that OpenAI applies to your API key.You can use the Welcome window to create and enter an OpenAI API key, and to open the Main Window.Main WindowYou can access the Main window from the addon’s Welcome window or menu item Tools → Pixel Crushers →Dialogue System → Addon for OpenAI → Main Window.On the Main Window, you can access these windows:•Generate Conversation: Generate a new conversation or set of barks.•Translate Database: Translate your database to one or more languages.•Freeform Chat: Talk with OpenAI in a format similar to ChatGPT.The Addon for OpenAI also adds AI buttons to several locations in the Dialogue System’s Dialogue Editor window. You can click these AI buttons to access additional features.Generate ConversationAccess the Generate Conversation window from the Main Window. Here, you can create a new linear conversation between two actors or create a bark conversation.Generate ConversationTo create a conversation, specify a title, participants, action, and topic. For example, the screenshot above will prompt the GPT_3_5_Turbo language model to generate a conversation titled “War” between Private Hart and Sergeant Graves regarding the purpose of war. Then click Generate. When the Addon receives a response from OpenAI, it will show the generated conversation. If you want to adjust the conversation, enter Refinement Instructions and click Refine. To add the conversation to your dialogue database, click Accept.When creating a conversation, the prompt will also include the participants’ Description fields and any actors mentioned in the topic. Include the actor’s name in the Description field, such as:To generate branching dialogue, you can use the addon’s Dialogue Smith integration.Generate BarksTo generate barks, click the Generate Barks toolbar. The UI will appear the same as Generate Conversation with the addition of a Num Barks slider. Set the slider to the number of barks you’d like to generate, and click Generate Barks.When you’re satisfied with the results, click Accept to add a conversation containing the barks.Revise TextAccess the Revise Text window by clicking the AI button next to a field in the Dialogue Editor such as the Dialogue Text field:You can specify how you want to refine the text by specifying refinement instructions and clicking Refine, or click Fix Grammar & Spelling to fix grammar and spelling.If the Num Variations slider is set to 1, you will receive one proposed revision. To accept it, click Accept.If Num Variations is greater than 1, you will receive multiple suggestions. To accept one of the suggestions, click the Accept button next to it. Or you can click Use All to add them all to the conversation, replacing the original dialogue entry node. If the original node was a non-player node, it will be replaced by a group node that calls RandomizeNextEntry() to randomly choose from the variations.Translate FieldAccess the Translate Field window by clicking the AI button next to any localization field in the Dialogue Editor, such as this field in a dialogue entry node: (See Localization)Enter optional refinement instructions, then click Translate. To accept the translation, click Accept. Note: Translate Field defaults to the Curie language model, but you can change it to GPT3_5_Turbo if you prefer.Translate DatabaseAccess the Translate Database window from the Main Window. This window allows you to translate the entire database. Define the languages that you want to translate to in the Dialogue Editor first. (See Localization)By default, to minimize costs, this window will only translate localization fields that are blank. To retranslate fields that already have content, tick Retranslate All.Then tick the languages that you want to translate to, and click Translate.If you have a medium or large database, this operation will take some time. OpenAI limits API calls to 60 per minute, so the operation will batch several requests and then wait a little before continuing. Note: Translate Field defaults to the Curie language model, but you can change it to GPT3_5_Turbo if you prefer.Freeform ChatAccess the Freeform Chat window from the Main Window. This window operates similarly to ChatGPT. You can repeatedly enter text in the Prompt field to continue a dialogue with the OpenAI language model. You can then copy this to the clipboard for use elsewhere, such as pasting generated code into a script, such as: (continued on next page)Generate PortraitsTo access the Generate Portraits window, inspect an actor in the Dialogue Editor and click Generate AI Portraits:Under Main Portrait, the actor’s current portrait appears on the left. If you have generated new potential images, they will be shown to the right of the Current image:To use one of these potential images as the main portrait, click the Use button. You can then save the image as an asset in your project, and it will be assigned to the actor.To add more portraits to the actor’s Portrait Sprites list, click Add Portrait.For each additional portrait, you can enter a Variation Prompt. Then click Generate Portrait to generate a variation of the actor’s main portrait image based on the prompt.ElevenLabs Voiceover Audio GenerationYou can use ElevenLabs’ speech synthesis API to generate voiceover audio for your dialogue. First create a profile on https://elevenlabs.io/ and create an API key. Then enter this API key in the addon’s Welcome window. Then you can assign voices to actors and generate audio for dialogue entries. Assign Voices To ActorsIn the Dialogue Editor, inspect an actor and click Select next to the V oice field.Then select an AI voice actor from the dropdown. To preview what the voice actor sounds like, enter some preview text and click Preview. To assign the selection to your actor, click Accept.Generate Voiceover AudioTo generate voiceover audio for a dialogue entry, click the Sequence field’s AI button:This will open the Generate V oiceover window:Click Generate to use the ElevenLabs API to generate voiceover audio. When the operation is done, it will play the audio. If you want to hear it again, click Preview. To accept the audio, click Accept. Save the audio file as an asset in your project. Some notes on saving audio: (see next page)Notes on Saving Audio Files•If the open scene has a Dialogue Manager, the default filename will be entrytag name for the dialogue entry as specified by the Dialogue Manager’s Entrytag Format selection. Otherwise it will use the default entrytag format: ActorName_ConversationID_EntryID.•If you’ve enabled Addressables support by clicking the Dialogue System’s Welcome Window > USE_ADDRESSABLES checkbox, the audio file will be marked Addressable, and theaddressable key will be set to the entry’s entrytag.•Otherwise save the file in a Resources folder.•Clicking Accept will not add a sequencer command to the entry’s Sequence field. To handle it manually for a single entry, you can drag the audio file into the Sequence field. However, acommon way to set up voiceover is to set the Dialogue Manager’s Default Sequence tosomething like: AudioWait(entrytag) and leave the Sequence field blank.Dialogue Smith IntegrationDialogue Smith can fill in dialogue for a pre-constructed dialogue tree. Create a conversation tree without dialogue text, and put prompts in the dialogue entries’ Title fields. For example, the conversation below is for a quest giver NPC that offers a quest:This is especially powerful if you create conversation templates and then create conversations from the templates using Menu > Templates > New From Template. In fact, the conversation tree above was created by selecting the built-in quest template.Then inspect the conversation’s properties, put the conversation’s context (e.g., background information) in its Description field, and click the AI button:This will open the Dialogue System Addon window to the Branching Dialogue panel. Verify that the Context is what you want to use, and click Generate:Dialogue Smith will generate up to three dialogue text variations for every dialogue entry whose Dialogue Text field is blank. This will take some time, so please be patient. When the operation is done, the panel will show the dialogue text variations for each dialogue entry:Tick the ones you want to use. If you tick more than one variation for an NPC dialogue entry, the conversation will randomly choose from the variations at runtime. If you tick more than one variation for a PC dialogue entry, they will be presented as a player response menu. Then click Accept.Runtime DialogueThe Dialogue System Addon for OpenAI can also use the OpenAI API at runtime to generate conversations and barks. Runtime operation is entirely optional. If you decide to use runtime generation, consider how you will handle API keys. To avoid excessive charges, it’s probably best to require end users (e.g., players) to provide their own API keys.To configure runtime generation, add a Runtime AI Conversation Settings component to your dialogue UI:Add three UI elements to your dialogue UI, and assign them to the component:•Waiting Icon: A GameObject that will be shown while waiting for a response from OpenAI.For example, this could be an animated hourglass or a spinning ball.•Chat Input Field: Input field where the player will enter freeform text responses if running a freeform text input conversation. You can usually assign the existing Text Field UI here.•Goodbye Button: Button that the player can click to end the conversation instead of entering text into the Chat Input Field. You do not need to assign anything to its OnClick() event.You can also add these optional elements:•Image & Image Size: Used to show generated images in CYOA (Choose Your Own Adventure) mode.•Record Button: Starts recording speech input.•Submit Recording Button: Stops recording speech input and submits the recording to OpenAI for text transcription.•Microphone Devices Dropdown: Dropdown that lets user select which microphone to record.•Max Recording Length: Limits recorded audio clip size to this length in seconds.•Recording Frequency: Records from microphone at this frequency.Then add a Runtime AI Conversation component to your scene. This component holds the configuration for a single conversation or bark. To activate it at runtime, call its Play() method. For example, you can add it to an NPC with a Usable component, and configure the Usable’s OnUse() event to call RuntimeAIConversation.Play. In the screenshot below, the Runtime AI Conversation component’s Play() method is invoked by a UI Button’s OnClick() event:Set these fields:•Actor: For conversations, typically the player. For barks, the barking character.•Conversant: The other participant, typically an NPC.•Topic: What the conversation or bark is about.•Assistant Prompt: Optional guiding instructions for OpenAI.•Mode: Can be:◦Freeform Text Input: Plays a conversation line by line, generating responses to each line of player input. The player can end the conversation by clicking the Goodbye button. The NPCwill end the conversation if the conversation history approaches Max Tokens.◦Response Menu: Generates a complete conversation up-front and runs it like a prewritten conversation using the regular player response menu and/or player subtitle panel.◦Bark: Generates and plays a single bark through the Actor.•Text Input Prompt: Only used in Freeform Text Input mode. The label shown in front of the Chat Input Field.•Max Text Input Length: Only used in Freeform Text Input mode.Adding Runtime ContextNote: You can use the markup tags [var=variable] and [lua(code)] in your Topic. This allows you to change information in the topic text at runtime based on Dialogue System variable values and/or the values of Lua expressions.The next pageRuntime DemoThe Demo folder contains a bare bones scene that demonstrates all five types of runtime dialogue generation:•Freeform text input conversing with an NPC. This conversation is generated line by line. If you’ve specified an ElevenLabs API key in your dialogue UI’s Runtime AI ConversationSettings component, it will also generate voiceover audio immediately after generating eachline of dialogue. You can use text input or microphone speech input.•Response menu-based conversation. Demonstrates a conversation between an NPC and the player using the dialogue UI’s response menu. The conversation is generated first and thenplayed. V oiceover audio is generated as each line is played.•NPC-NPC conversation. Demonstrates a conversation involving two NPCs, without player interaction. The conversation is generated first and then played. V oiceover audio is generated as each line is played.•Bark. Demonstrates a generated bark.•CYOA. Choose-your-own-adventure story with freeform text input or speech input.To play the Runtime Demo, you must first enter your OpenAI API key in the Runtime AI Conversation Settings component located on Dialogue Manager > Canvas > Basic Standard Dialogue UI.You may also enter an ElevenLabs API key if you want the demo to generate voiceover audio. If you’ve entered an ElevenLabs API key, make sure you’ve assigned voices to the actors in your dialogue database.CYOA mode can optionally use DALL-E to generate images for each stage of the adventure. To enabled this, add an Image to the Dialogue Panel and assign it to Runtime AI Conversation Settings.Questions? Feature Suggestions?If you’re stuck or have feature suggestions, please contact us.

你不知道的一些电子烟术语
你不知道的一些电子烟术语名词释义：一. 常用术语：Rebuildable （可重建式）- 指雾化芯可以被重建，即雾化芯可以DIY。
RBA = Rebuildable Atomizer的缩写，即可重建式雾化器的统称。
RTA = Rebuildable Tank Atomizer的缩写，即可重建式储油雾化器。
RDA = Rebuildable Dripping Atomizer，即可重建式滴油雾化器。
【小知识：RBA是所有可重建式雾化器的总称，它包含了两个主要分支，即RTA（储油式雾化器）和RDA（滴油雾化器）】RSST - 创世纪类雾化器，是以一种原名就叫做创世纪的雾化器为设计蓝本的雾化器类型，即“上吸油式”雾化器，因为只有这种结构才可以使用不锈钢网子来做导油材料，因此有时候RSST也称为网子雾化器。
KFLP - KayFun Lite Plus 的缩写，它并不是指某一类雾化器，而是指Kayfun公司的一款经典的雾化器产品。
2. 发热器件：机械杆- 不能预设功率的电子烟输出器件，特点是结构简单，相当于电池正负极直接接在雾化器上，在低电阻芯子下输出非常粗暴而有力，但存在一定安全隐患。
机械盒子- 方形机械杆，一般来说采用两节电池并联供电，因其并联结构决定了其输出功率与单电的机械杆是相等的，并不会“更暴力”，但在持续稳定输出和续航上比单电机械杆有优势。
带保护机械杆- 原理与机械杆大致相同，增加了比如电池正负极、过流、短路等保护功能，但正因为增加了一些保护器件，它的输出不如纯机械杆那么"暴力"。
调压盒子- 也称盒子，指可以预设功率的电子烟输出器件，除了一系列完善的保护措施外，还可以对输出功率进行加减调节或者温度控制等功能。
欧姆盒子- 调压盒的一种，内置DC-DC模块，只有有限的几档功率可调，但除了功率输出这部分外摒弃了调压盒其余的所有功能，因此它比标准调压盒更为“暴力”调压杆子- 与调压盒子一致，只是做成了圆杆状。
