    • To facilitate hands-free operation, a communications device holder (110, 300, 400) includes a tongue (202) that is adapted to mate with and be latched within a seat belt buckle (112) of an unoccupied vehicle passenger position. The communications device holder includes a docking assembly (200) that is adapted to receive and securely hold a communications device (120). The docking assembly includes interfaces for power, speakers, microphones and the like. A flexible member (302) is alternatively attached to the tongue to flexibly configure the position of the device holder. A seat belt buckle (402) is optionally attached to the communications device holder for securing the device holder both with the seat belt buckle for a passenger position and with the seat belt.
    • 为了便于免提操作,通信设备保持器(110,300,400)包括舌头(202),其适于与未占用的乘客位置的座椅安全带扣(112)配合并被闩锁。 通信设备保持器包括对接组件(200),其适于接收和安全地保持通信设备(120)。 对接组件包括用于电力,扬声器,麦克风等的接口。 柔性构件(302)交替地附接到舌部以灵活地配置装置保持器的位置。 安全带扣(402)可选地附接到通信装置保持器,用于将装置保持器与用于乘客位置的安全带扣和安全带固定。

    • A fault detection system for determining whether a fault exists with a rotating element of a vehicle. The system includes a transducer, a diagnosis sampler, a sensor, and a controller. The transducer may be a microphone located in the vehicle for converting sounds to an electrical signal. The electrical signal includes a noise component generated from the rotating element. The diagnosis sampler is connected to the transducer and provides a sample of the electrical signal from the transducer to the controller. The sensor obtains data relating to the rotating element. The controller has functional aspects such as a synchronous resample, a spectrum analysis, and a fault detect. The synchronous resample has the capability of synchronizing the sample of the electrical signal with the data from the sensor to form a synchronized envelope. The spectrum analysis has the capability of forming a spectra from the synchronized envelope of the electrical signal, where the spectra is associated with the noise component generated from the rotating element. The fault detect has the capability of determining (from the formed spectra) whether the fault exists with the rotating element. There is also a method of detecting a fault associated with a rotating element in a vehicle using the above-described system.
    • 一种用于确定车辆的旋转元件是否存在故障的故障检测系统。 该系统包括换能器,诊断取样器,传感器和控制器。 传感器可以是位于车辆中的麦克风,用于将声音转换成电信号。 电信号包括从旋转元件产生的噪声分量。 诊断采样器连接到传感器,并提供从传感器到控制器的电信号采样。 传感器获得与旋转元件有关的数据。 控制器具有诸如同步重采样,频谱分析和故障检测等功能方面。 同步重采样具有将电信号样本与来自传感器的数据同步以形成同步信封的能力。 光谱分析具有从电信号的同步包络形成光谱的能力,其中光谱与由旋转元件产生的噪声分量相关联。 故障检测具有确定(从形成的光谱)旋转元件是否存在故障的能力。 还有一种使用上述系统来检测与车辆中的旋转元件相关联的故障的方法。
