    • A tracking device including a housing including a transceiver, a battery connected to the housing and an antenna connected to the housing, where the antenna is wrapped by at least one photovoltaic sheet and where the photovoltaic sheet is operable to recharge the battery. The tracking device includes a global positioning device, a radio frequency triangulation device and a microchip included in the housing. The tracking device also includes a microcontroller included in the housing, where the microcontroller is in communication with the battery, global positioning device, radio frequency triangulation device and microchip. The microcontroller is operable to cause the microchip to generate a position signal using the global positioning device and the radio frequency triangulation device to transmit the position signal via the transceiver and the antenna to enable user to detect a position of the tracking device.
    • 一种跟踪装置,包括壳体,包括收发器,连接到壳体的电池和连接到壳体的天线,其中天线被至少一个光伏片包裹,并且其中光伏片可操作以对电池再充电。 跟踪装置包括全球定位装置,射频三角测量装置和包括在壳体中的微芯片。 跟踪装置还包括微处理器,其包括在壳体中,其中微控制器与电池,全球定位装置,射频三角测量装置和微芯片通信。 微控制器可操作以使微芯片使用全球定位设备和射频三角测量设备产生位置信号,以经由收发器和天线发送位置信号,以使用户能够检测跟踪设备的位置。
