制造商Zare Srl将3D打印机集成到工厂供应链
【PConline 资讯】意大利3D打印机制造商Roboze以发布可使用高性能工业强度材料（如PEEK和PEI）的桌面3D打印机而闻名。去年，该公司将其经济实惠的RobozeOne+4003D打印机改造为一款完全工业化的3D打印机，而更新的机器引起了Roboze客户ZareSrl的注意，这家公司也在意大利。Zare是名副其实的AM工厂，凭借3D打印技术和广泛的材料知识，能够制作原型和最终部件。2017年底，Zare与Roboze进行了深入的交流，了解RobozeOne+4003D打印机是否可以引入标准化的UNIEN认证生产流程。Zare通过确保短暂的内部供应链来缩短生产周期并保护其客户项目的机密性，而RobozeOne+400将帮助公司继续这样做。Zare公司的质量经理Torelli说：&有必要定义新的公司程序，可以将原型和权威性作品都纳入Zare已经表征的每一个元素的标准。我们现场核实，新流程的应用不会减慢或影响交付条件。&最终，讨论取得了成功，因此Zare已于最近建立了新的企业流程，以便将3D打印机引入到其工厂供应链的FDM部门。Roboze营销总监IlariaGuicciardini表示：&Roboze已经在FDM技术的专业3D打印方面引入了各种创新。Roboze无带式系统允许通过插入与小齿轮接触的螺旋齿条，直接机械传递到X和Y轴。这个获得专利的解决方案可实现高达25微米的精度，达到前所未有的质量水平。另一个创新的元素绝对是在内部设计和生产的HVP（高粘度聚合物）挤出机。HVP挤出机具有一个内部通道，可在挤出过程中加快高粘度聚合物的速度，同时降低粘度并控制溶胀过程，从而提高打印聚合物（如PEEK）的速度。在Zare安装的RobozeOne+400将承受连续的工厂压力，因此公司将能够为客户生产高性能的高科技聚合物PEEK的部件。Zare总经理Pasquali说：&使用PEEK制作3D打印部件在金属难以成为最佳选择的领域非常有用。这为我们的客户提供了这个机会，扩大了设计的申请数量，充分利用了添加剂的特点。&PEEK（聚醚醚酮）是一种超高科技聚合物，可提供出色的3D打印效果。独特的材料在高酸性或碱性环境下以及在高温下稳定，并具有优异的热稳定性和化学惰性。PEEK在高冲击应用以及需要长时间暴露在高温环境下的应用场合非常流行，例如航空航天和国防、生物医学、赛车运动和石油天然气行业。Zare公司正在使用RobozeOne+4003D打印机和高性能PEEK材料来创建小型工业仪器，如钻孔模板、间隔元件和支架，这些工具可以用来使日常的批量生产更容易。在批量生产中创建这样的辅助工具就是所谓的快速模具，它使企业对工业3D打印更慢、更谨慎，因为它会影响伴随的设备，而实际上并没有改变工业产品生产的供应链。通过将PEEK材料用于这些类型的仪器，可以进行设计，使其具有耐磨性，并具有更高的机械性能。&与我们FDM部门的三台Fortus900mc（RobozeOne+400的构建尺寸是200x200x200mm）相比，即使单件打印尺寸减小，PEEK材料提供的可能性也是前沿的，具有卓越的机械特性和出色的耐化学性，&Zare销售经理Pisciuneri说。&无论是在功能原型还是确定的应用领域，PEEK都是提交给客户评估的一个新的最佳选择。&Roboze在其RobozeOne+4003D打印机中提供的高质量技术解决方案使Zare公司相信，即使像PEEK这样的材料也能以适合其客户需求的方式进行挤压，反过来将利用增材制造提供的许多新的生产可能性。来源：3D虎

Isn't it simple ?You have to just replace $zephyr_base/samples/bluetooth/peripheral/src/main.c with following code.These are some useful links for reference,( https://play.google.com/store/apps/details?id=no.nordicsemi.android.nrfblinky&hl=en )(http://docs.zephyrproject.org/api/bluetooth.html )(http://docs.zephyrproject.org/samples/bluetooth/blueto...
Interfacing the Nordic Thingy:52 from the Amazon Alexa Voice Service just had to be done! In this blog post I will briefly explain how this demo was set up, but I will direct you to the GitHub page if you need more detailed information than what i provide here.

After the release of nRF52840 Engineering B we have received several inquiries about the difference between Engineering A (nRF52840-QIAAAA) and Engineering B (nRF52840-QIAABB) reference designs. One reason for the inquiries is that after swapping Engineering A with Engineering B samples customers experienced that the radio stopped working. The symptoms being that everything but the radio seemed to work in their application. While this is highly unfortunate, it is to be expected because there was a vital d...
I am trying to save the address of program counter when a watchdog reset occurs. In order to do that I use gcc's `__builtin_return_address(0)` from within the SDK's `nrf_drv_wdt.c:WDT_IRQHandler()`.What this returns is `0xfffffff9`. If I interpret the ARM spec correctly, this address is in the area reserved for the chip vendor.- What is at that address?- Can I extract the PC before WD reset using the gcc builtin? Another function?- What is the recommended way of getting the address when the watchdog timed...
I'm using the IoT bootloader from NRF52 SDK 14.2. When the bootloader has nothing to do and starts the main application, the FDS calls all fail in the main application. When I clear the UICR (nrfjprog -f nrf52 --eraseuicr), my main application launches (without using the bootloader) and the FDS calls work, it is only when the main application is launched through the bootloader that they fail. What am I missing?...

Through this framework, for\nexample, your app can respond to gestures on the touchscreen and enable\nfeatures such as drawing, accessibility, and printing.\u003C\u002Fp\u003E\u003Cp\u003EiOS tightly integrates with other programming\nframeworks and technologies too, such as Apple Pay, HealthKit, and ResearchKit,\nenabling you to design amazingly powerful apps.\u003C\u002Fp\u003E\u003Cp\u003E另外，为了定义iOS的界面，UIKit定义您app可以采用的功能。在这个框架之下，举例来说，您的app可以对触摸屏上的手势做出回应，并且使用绘画、无障碍功能和打印。\u003C\u002Fp\u003E\u003Cp\u003EiOS与其他编程框架和科技紧密结合，例如Apple Pay，HealthKit\nand Research Kit，使您可以设计超棒超强的app。\u003C\u002Fp\u003E&,&updated&:new Date(&T11:59:50.000Z&),&canComment&:false,&commentPermission&:&anyone&,&commentCount&:1,&likeCount&:2,&state&:&published&,&isLiked&:false,&slug&:&&,&isTitleImageFullScreen&:false,&rating&:&none&,&sourceUrl&:&&,&publishedTime&:&T19:59:50+08:00&,&links&:{&comments&:&\u002Fapi\u002Fposts\u002F2Fcomments&},&url&:&\u002Fp\u002F&,&titleImage&:&&,&summary&:&&,&href&:&\u002Fapi\u002Fposts\u002F&,&meta&:{&previous&:null,&next&:null},&snapshotUrl&:&&,&commentsCount&:1,&likesCount&:2},&&:{&title&:&iOS 10 人机界面指南：交互（一）&,&author&:&wu-rui-89&,&content&:&\u003Ch2\u003E\u003Cb\u003E3D Touch\u003C\u002Fb\u003E\u003C\u002Fh2\u003E\u003Cp\u003E3D Touch adds an additional dimension to\ntouch-based interaction. On supported devices, people can access additional\nfunctionality by applying varying levels of pressure to the touchscreen. Apps\ncan respond by displaying a menu, showing additional content, or playing an\nanimation. People don’t need to learn new gestures to interact with 3D Touch. They\nquickly discover the additional interactive dimension when they press lightly\non the screen and get a response.\u003C\u002Fp\u003E\u003Cp\u003E3D Touch给基于触摸的交互增添了一个维度。在支持该技术的设备上，人们可以通过给触摸屏施加不同级别的压力来实现附加功能。App会用显示菜单、展示附加内容或者播放动画来做出反应。人们不必学习用3D Touch交互的新手势。当他们在屏幕上轻轻按压并且获得回应时，他们会很快发现这个额外的交互维度。\u003C\u002Fp\u003E\u003Ch3\u003EHome Screen Interaction\u003C\u002Fh3\u003E\u003Cp\u003EOn the Home screen, pressing the icon\nof an app that supports 3D Touch displays an action view.

To peek\nat an item that supports this functionality, apply a little pressure to the\nitem with your finger. Simply lift your finger to exit the peek. To open the\nitem and see more detail, press a little harder until the item pops and fills\nthe screen. In some peek views, you can swipe up to reveal related action\nbuttons. For example, while peeking at a link in Safari, you can swipe up to\nreveal buttons for opening the link in the background, adding the link to your\nreading list, and copying the link.\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EPeek and Pop\u003C\u002Fb\u003E\u003C\u002Fp\u003E\u003Cp\u003E人们用3D Touch在一个临时出现在当前语境上方的视图里，预览一个项目，例如一个页面，一个连接或者文件。戳一个支持该功能的项目时，指尖用点力气按压该项目。只要抬起手指就能结束动作。为了开启该项目查看更多细节，请更用力按压直到该项目弹出并且充满屏幕。在一些Peek视图中，您可以向上滑来露出相关的动作按钮。例如，当戳Safari中的一个链接时，您可以向上滑来露出用于在后台打开连接、将链接添加到阅读列表、拷贝链接的按钮。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cstrong\u003EUse peeking to provide live, content-rich previews.\u003C\u002Fstrong\u003EIdeally, peeking gives enough information about an item to\naugment the current task, or helps you decide whether to fully engage the item.\nFor example, preview a link in a Mail message before deciding to open it in\nSafari or share it with friends.

Supplement haptics with visual and audible cues to ensure that important information isn’t missed.\u003C\u002Fp\u003E\u003Cp\u003E不要依赖单一的交流模式。不是所有的设备都支持所有的触觉反馈，而且人们可以选择在设置里完全关掉这个特性。另外，触觉反馈只在设备支持时出现，并且您的app是最新版的。用视觉和听觉补充触觉反馈，以保证重要信息不被错过。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EUse haptic when visual feedback may be occluded.\u003C\u002Fb\u003E Some interactions, such as dragging an object to a location onscreen, are hidden by the user’s finger. Consider generating feedback that lets the user know when they’ve reached a particular location or value.\u003C\u002Fp\u003E\u003Cp\u003E当视觉反馈可能被关闭时使用触觉反馈。有些交互，例如在屏幕上拖拽物体到某处，会藏在用户手指后面。考虑触发触觉操作，让用户知道他们已经到了某个特定的地方或者值。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EPrepare the system before initiating feedback.\u003C\u002Fb\u003E Because there may be some latency involved when providing haptic feedback, it’s best to get the system ready shortly before requesting the feedback. Otherwise, the haptics might come too late and feel disconnected from the user's actions or what they’re seeing on the screen.\u003C\u002Fp\u003E\u003Cp\u003E让系统触发反馈之前做好准备。因为在提供触觉反馈时可能会有一些等待时间，最好让系统在要求反馈之前不久就做好准备。否则，触觉反馈可能来的太迟，用户会感觉动作断开连接了或者与他们在屏幕上看到的失去联系。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003ESynchronize haptic with accompanying sound.\u003C\u002Fb\u003E Haptics don’t automatically synchronize with sounds. If you want an accompanying sound, you’re responsible for synchronizing it.\u003C\u002Fp\u003E\u003Cp\u003E同步触觉反馈和伴随的音效。触觉反馈不会自动与音效同步。如果您需要伴随的音效，您得同步它。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EFile Handling文件处理\u003C\u002Fb\u003E\u003C\u002Fp\u003E\u003Cp\u003EPeople shouldn’t need to think about the file system while creating, viewing, and manipulating files. If your app works with files, downplay file handling as much as possible.\u003C\u002Fp\u003E\u003Cp\u003E人们在创建文件、查看文件、操作文件时不应该为文件系统考虑过多。如果您的app与处理文件有关，尽可能淡化文件处理过程。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EInstill confidence that work is always preserved unless canceled or deleted.\u003C\u002Fb\u003E In general, don’t make people explicitly save files. Instead, save changes automatically at regular intervals, when opening and closing files, and when switching to another app. In some cases, such as while editing an existing file, save and cancel options may still make sense for the sake of confirming when the edits are actually captured.\u003C\u002Fp\u003E\u003Cp\u003E跟用户灌输信息，他们的作品除非被取消或者删除，总是被保存的。总的来说，不要让人们特地保存文件。取而代之，当打开或者关闭文件，还有切换到另一个app时，有规律的自动保存改动。在某些情况下，例如编辑一个已存在的文件，保存和取消选项还是有意义的，用于确认编辑真的发生了。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EDon't provide an option to create local-only files.\u003C\u002Fb\u003E Users often expect all of their files to be available on all of their devices. Whenever possible, your app should support cloud-based file storage through a service such as iCloud.\u003C\u002Fp\u003E\u003Cp\u003E不要提供只创造本地文件的选项。用户经常期望所有的文件在他们所有的设备上都能访问。任何可能的时候，您的app应该支持云文件，通过类似iCloud的服务。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003EImplement an intuitive and graphical file browsing interface.\u003C\u002Fb\u003E Ideally, use the system’s familiar document picker for browsing. If you implement a custom file browser, make sure it’s intuitive and efficient. File browsers work best when they’re highly graphical, providing visual representations of files. To speed navigation, minimize gestures, and consider providing a new document button, so people don’t need to go elsewhere to create a new document.\u003C\u002Fp\u003E\u003Cp\u003E使用直观的图形化的文件浏览界面。理想状况下，为浏览文件使用系统熟悉的文件挑选界面。如果您使用个性化的文件浏览器，确认它是直观高效的。文件浏览器在他们高度图形化，提供文件的视觉展示时最高效。为了提高浏览速度，少使用手势，考虑提供一个新建文件按钮，这样人们就不必去其他地方创建新文件了。\u003C\u002Fp\u003E\u003Cp\u003E\u003Cb\u003ELet users preview files without leaving your app.\u003C\u002Fb\u003E You can use Quick Look to let people view the contents of Keynote, Numbers, and Pages documents, PDFs, images, and certain other types of files, even if your app doesn’t actually open them.
