    • A tire pressure monitoring system includes a receiver for processing signals and alerting an operator of the vehicle should conditions within any of the tires fall outside a desired range. The transmitters within the tires emit shorter transmission signals during operation by eliminating transmission of the identification code. The receiver stores the identifier for each transmitter for comparison to subsequent transmissions. Subsequent transmissions do not include the identifier. The receiver combines the saved identifier with the value provided in the check portion of the incoming transmission. If the combination of the saved identifier with the value provided in the check portion meets a defined criteria, than the signal is recognized as originating from one of the transmitters.
    • 轮胎压力监测系统包括用于处理信号的接收器,并且在任何轮胎内的条件落在期望范围之外的情况下警告车辆的操作者。 通过消除识别码的传输,轮胎内的发射器在操作期间发射较短的传输信号。 接收机存储每个发射机的标识符,以便与随后的传输进行比较。 后续传输不包括标识符。 接收器将保存的标识符与传入传输的检查部分中提供的值组合。 如果保存的标识符与检查部分中提供的值的组合满足定义的标准,则该信号被识别为源自发射机之一。

    • A method for thermal forming includes determining a process window for initiating cooling, locally heating at least one region on a specimen to achieve a pre-selected geometry deformation, initiating active cooling of the heated region within the process window to control at least one material property of the specimen at the heated region and actively cooling the heated region to a pre-selected temperature. A system for thermal forming includes a thermal source for heating the region on the specimen to achieve a pre-selected geometry deformation, an active cooling module for cooling the region to a pre-selected temperature and a control module to control at least one of the thermal source and active cooling module in accordance with a process window to initiate active cooling to control at least one material property of the specimen at the heated region. The process window has an upper time limit for initiating cooling.
    • 用于热成型的方法包括确定用于启动冷却的工艺窗口,局部加热样品上的至少一个区域以实现预先选定的几何变形,启动在工艺窗口内的加热区域的主动冷却以控制至少一种材料性质 的样品在加热区域并主动地将加热区域冷却到预选温度。 一种用于热成型的系统包括用于加热样品上的区域以实现预先选择的几何变形的热源,用于将该区域冷却到预选温度的主动冷却模块和控制模块中的至少一个 热源和主动冷却模块,其根据工艺窗口启动主动冷却以控制加热区域处的样品的至少一种材料特性。 过程窗口具有启动冷却的上限时间。
