Introduction

介绍

Long time riders might remember the original fuzzy, pink Carstache emblem that made Lyft universally recognizable. Over the years, the emblem dropped the fuzz for pink lights in the Glowstache and later evolved with more colors as the beloved Amp, which has been in active use for over seven years! Recently, Lyft has introduced its brighter, bolder next generation emblem — Glow. Glow provides a daytime visible, auto-dimmable display showing rider customizable colors and new animations to help them find their ride faster. Glow also has enhanced GPS and IMU sensors for improved driver location accuracy.

长期乘客可能还记得最初的模糊粉红色Carstache标志，它使Lyft广为人知。多年来，标志从Glowstache的粉红灯光变成了更多颜色的心爱的Amp，已经使用了七年多！最近，Lyft推出了更亮、更大胆的下一代标志——Glow。Glow提供了白天可见的自动调光显示，显示乘客可自定义的颜色和新动画，以帮助他们更快地找到乘车。Glow还配备了增强型GPS和IMU传感器，以提高司机位置的准确性。

Prior to Glow, Lyft has IoT development experience with not only the Amp but also with Bikes and Scooters, Halo ad displays, and even Autonomous research vehicles. Each of these were built with bespoke solutions for their use case, which were hard to retrofit for new device types. Observing similar functionality across these siloed systems motivated us to collaborate with these teams, where feasible, to build new IoT middleware services which could provide a unified framework for managing a variety of devices.

在Glow之前，Lyft不仅在Amp上拥有物联网开发经验，还在自行车和滑板车，Halo广告显示器，甚至自动驾驶研究车辆上拥有经验。每个设备都使用了为其用例构建的定制解决方案，难以适应新设备类型。观察到这些孤立系统中的类似功能激发了我们与这些团队合作的动力，以构建新的物联网中间件服务，为管理各种设备提供统一的框架。

Just like for the Amp, we continue to use Bluetooth Low Energy (BLE) as the communication mechanism between the Glow device and the driver’s smartphone, instead of opting for a cellular chip in the device. We leverage the driver’s phone as an “IoT gateway” which serves as a communicati...
