    • Load detection circuitry is provided that may be used to monitor an output line. The load detection circuitry may include one or more current sensing resistors. A monitor circuit can measure voltages across the current sensing resistors to determine whether current is flowing through a load connected to the output line. In configurations with multiple different current sensing resistors, the monitor circuit can determine the amount of current that is flowing through the load based on the measured voltages. A switch may be interposed between the current sensing resistor and the output line. A current-limited voltage regulator may supply a voltage to the output line. The monitor circuit may periodically open the switch and monitor resulting voltage changes on the output line to determine whether an electronic device or other load is attached. Opening of the switch may be inhibited whenever current is sensed through a current sensing resistor.
    • 提供可用于监视输出线的负载检测电路。 负载检测电路可以包括一个或多个电流感测电阻器。 监控电路可以测量电流检测电阻上的电压,以确定电流是否流过连接到输出线的负载。 在具有多个不同电流检测电阻的配置中,监视电路可以基于测量的电压确定流过负载的电流量。 开关可插在电流检测电阻和输出线之间。 电流限制电压调节器可以向输出线路提供电压。 监视器电路可以周期性地打开开关并监视输出线上的所得电压变化,以确定电子装置或其他负载是否被连接。 每当通过电流感测电阻感测到电流时,可以禁止开关的断开。

    • Methods and systems for powering-off a Bluetooth device from a linked device are provided. A device can transmit a Bluetooth signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more Bluetooth networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a Bluetooth network through a single device.
    • 提供了从链接设备断开蓝牙设备的方法和系统。 设备可以将蓝牙信号发送到链接的设备以​​指示链接的设备关闭电源。 以这种方式,用户只需手动关闭一个设备,导致所有链接的设备都关闭电源。 该过程可以由用户通过与要断电的设备直接链接的设备或通过一个或多个蓝牙网络与要断电的设备间接连接的设备来发起。 当存在一组预定条件时,该过程也可以由设备自动启动。 一旦指示这样做,设备可以启动预定的断电过程,其可以涉及终止任何正在进行的功能并且关闭各种子系统。 根据本发明,用户可以通过单个设备发起蓝牙网络上的所有设备的断电。
