    • Electro static discharge (ESD) protection is provided for electronic devices with integrated circuits, such as for example heart rate monitors. The ESD protection protects against voltage accumulation and discharge through device external parts that are connected to internal device circuitry. The ESD protection isolates the internal device circuitry and provides a low impedance path over which electro static charges and any transient voltages in the device may discharge. The integrated circuits, electrical components, and other parts protected from ESD may be connected to monitor circuitry and be externally exposed, such as sensing or measurement parts exposed outside the device. The external parts may include a sensing case back, sensing push-buttons, or other components that provide a signal to or are otherwise in communication with the internal device circuitry.
    • 为具有集成电路的电子设备(例如心率监测器)提供静电放电(ESD)保护。 ESD保护通过连接到内部器件电路的器件外部部件防止电压累积和放电。 ESD保护隔离内部器件电路,并提供低阻抗路径,静电电荷和器件中的任何瞬态电压可以放电。 集成电路,电气元件以及其他不受ESD保护的部件可能连接到监视器电路并被外部暴露,例如暴露在设备外部的感测或测量部件。 外部部件可以包括感测壳背,感测按钮或向内部设备电路提供信号或以其他方式通信的其他组件。

    • A heart rate monitor determines a heart rate for a primary subject by reducing noise and cross-talk from unwanted signal transmission sources. A set of pulse peaks having about the same amplitude and an amplitude greater than any other set of peaks are processed to determine a subject's heart rate, while data having an amplitude below that of the set of peaks is ignored. To retrieve enough data to determine a peak amplitude, the signal having heart rate information is sampled at a frequency higher than a normal sampling frequency. In some embodiments, if no data is received for a set time period which is in or above the range, the threshold resets to zero under an assumption that the primary subject is no longer within transmitting range.
    • 心率监测器通过减少来自不想要的信号传输源的噪声和串扰来确定主要受试者的心率。 处理具有大约相同幅度和幅度大于任何其它峰值集合的一组脉冲峰值以确定受试者的心率,而忽略具有低于该组峰值的幅度的数据。 为了检索足够的数据以确定峰值幅度,具有高于正常采样频率的频率的具有心率信息的信号被采样。 在一些实施例中,如果在等于或高于该范围的设定时间周期内没有接收到数据,则在假设主要被摄体不在发送范围内的情况下,阈值复位为零。
