    • A radio is defined in electrical communication with a processor on an integrated circuit chip. The radio is defined to operate at an international frequency, and is defined to be powered on and off in accordance with a control signal to be transmitted by the processor. A location determination device is defined to electrically communicate with the processor. The location determination device is also defined to be powered on and off in accordance with a control signal to be transmitted by the processor. A power source is defined to supply power to the processor, the radio, and the location determination device. The processor, radio, location determination device, and power source are integrated together in a portable device that can be affixed to a moveable asset. A power management program is implemented to enable long-term deployment of the portable device without replacement of the power source.
    • 无线电被定义为与集成电路芯片上的处理器电通信。 无线电被定义为以国际频率工作,并且被定义为根据要由处理器发送的控制信号被加电和关断。 定位位置确定装置与处理器电连通。 位置确定装置还被定义为根据要由处理器发送的控制信号而被加电和关断。 电源被定义为向处理器,无线电装置和位置确定装置供电。 处理器,无线电,位置确定装置和电源被集成在可附加到可移动资产的便携式装置中。 实现电源管理程序以便能够在不更换电源的情况下长期部署便携式设备。
