Hillcrest Laboratories近日于美國馬里蘭州舉行的ARM TechCon Expo上展示首款專為 Android 設(shè)計(jì)可執(zhí)行于ARM的傳感器中樞(sensor hub)。Hillcrest的首款sensor hub名為SH-1兼容于 Android 4.3” Jelly Bean操作系統(tǒng)，可作為純軟件使用或預(yù)整合于Atmel低功耗微控制器(MCU)中。 Hillcrest Labs資深行銷副總裁Chad Lucien指出：“許多有關(guān)sensor hub的應(yīng)用已廣泛出現(xiàn)在Windows 8市場中。三星的智能手機(jī)和平板都使用了sensor hub，如今蘋果也為其 iOS 加進(jìn)自有的 M7 sensor hub微控制器。因此，我們看到 Android 開發(fā)人員對于加緊趕上 sensor hub 的開發(fā)產(chǎn)生非常濃厚的興趣。Hillcrest的SR-1讓Android開發(fā)人員能快速建置超越9軸傳感器融合而實(shí)現(xiàn)獨(dú)特功能的sensor hub ，從而使OEM能夠善用手勢辨識與全時(shí)激活的情境感知等功能，從而實(shí)現(xiàn)產(chǎn)品差異化?！? sensor hub可卸載應(yīng)用處理器對于智能手機(jī)、平板電腦、筆記本電腦、可穿戴式設(shè)備或物聯(lián)網(wǎng)(IoT )設(shè)備中所有傳感器的管理任務(wù)。例如，微軟(Microsoft)為其Window 8 增加慣性傳感器支持。sensor hub透過執(zhí)行9軸傳感器(三個(gè)3軸MEMS慣性傳感器：加速度計(jì)、陀螺儀與磁力計(jì))融合協(xié)助進(jìn)行管理，從而釋放應(yīng)用處理器負(fù)載，為用戶帶來更佳體驗(yàn)。 除了執(zhí)行傳感器融合功能以外， SH -1 還可藉由其Freespace Motion Elements常用手勢庫執(zhí)行手勢辦識。例如，OEM可讓用戶以主題瀏覽大量影像或音樂數(shù)據(jù)庫。SH-1還提供全時(shí)激活的動(dòng)作偵測與情境感知功能──例如，感知用戶將裝置放在口袋中，應(yīng)用處理器隨即自動(dòng)關(guān)閉以節(jié)省電池電量。 Hillcrest 直接授權(quán)SR -1軟件給OEM，使其可建置于各自的ARM微控制器中，或者也可取得預(yù)先配置的低功耗Atmel微控制器。 Hillcrest 的SR -1并為所有常見的MEMS慣性傳感器、磁性與環(huán)境傳感器配備最佳化驅(qū)動(dòng)器。目前已經(jīng)取得Hillcrest動(dòng)作處理技術(shù)授權(quán)的公司包括Eastman Kodak、英特爾(Intel), LG Electronics、Logitech、Roku、SMK Electronics、Sony、TCL Multimedia與Universal Electronics (UEI)等。

{pagination} Sensor Hubs Arrive for Android R. Colin Johnson PORTLAND, Ore. — The first sensor hub specifically designed for Android running on ARM was demonstrated today by Hillcrest Laboratories Inc., of Rockville, Md., at the ARM TechCon Expo (Oct. 30-31, Santa Clara, Calif.). Hillcrest's first sensor hub -- dubbed SH-1 -- is compatible with the Android 4.3 "Jelly Bean" operating system and is available either as software-only or pre-integrated with an Amtel low-power microcontroller. Chad Lucien, senior vice president of sales and marketing for Hillcrest Labs, told EETimes: There is a lot of activity with sensor hubs in the Windows 8 market. Also Samsung's smartphones and tablets all use sensor hubs, and now Apple has its own M7 sensor-hub microcontroller for iOS. Consequently we are seeing very strong interest among Android developers to catch up in sensor hubs. Our SR-1 lets Android developers quickly implement a sensor hub that does unique things, which go beyond just nine-axis sensor fusion, allowing our OEMs to differentiate themselves with gesture recognition and always-on context awareness functions. Hillcrest's first Sensor Hub (SH-1) featuring its Freespace sensor fusion, gesture recognition, and context-aware algorithms comes pre-integrated with Atmel's SAM D20 ARM Cortex M0+ based microcontroller.

(Source: Hillcrest) A sensor hub off-loads the application processor from managing all the sensors studding a modern smartphone, tablet, laptop, wearable device, or Internet of Things (IoT) device. Microsoft, for instance (following Apple's lead as does Samsung and most other smartphone and tablet makers) mandated that Window 8 developers include a full complement of inertial sensors. A sensor hub helps manage them by performing the nine-axis sensor fusion across three triple-axis micro-electromechanical system (MEMS) inertial sensors -- accelerometer, gyroscope, and magnetometer -- thereby freeing up the application processor to be more responsive to the user. In addition to the sensor fusion performed by all sensor hubs, the SH-1 also performs gesture recognition from its Freespace MotionElements library of commonly used gestures. For instance, OEMs can allow their users to browse large libraries of images or music albums by tilting the device so the "covers" smoothly flow by at a speed determined by the inclination. The SH-1 also provides activity tracking and "context awareness" for always-on functions -- such as ascertaining when users have the device in their pocket -- so the application processor can be turned off to conserve battery life while waiting for the context to change. Hillcrest licenses the SR-1 software directly to OEMs, who can then implement it on their own ARM microcontrollers, or they can get it already preconfigured for a low-power Atmel microcontroller. In the Atmel booth at the ARM TechCon Expo, Hillcrest demonstrated its algorithms running on Atmel's latest SAM D20 ARM Cortex M0+ based microcontroller. Hillcrest's SR-1 also comes with optimized drivers for all the popular brands of MEMS inertial, magnetic, and environmental sensors. Companies that have already licensed Hillcrest's motion-processing technologies include Eastman Kodak, Intel, LG Electronics, Logitech, Roku, SMK Electronics, Sony, TCL Multimedia, and Universal Electronics (UEI).
