  • Wireless sensing device and wireless network sensing system
    Patent number: 7859405
    Abstract: A wireless sensing device includes a processing module, a wireless communication module, at least one sensing element, a power module and a power-monitoring module. The wireless communication module is electrically connected with the processing module to transmit or receive a wireless communication signal. The sensing element is electrically connected with the processing module to transmit a sensing signal to the processing module. The power module is electrically connected with and supplies a power to the processing module, the wireless communication module and the sensing element. The power-monitoring module is electrically connected with the processing module and the power module to transmit a power-monitoring signal to the processing module.

  • WIRELESS NETWORK INTERFACE CARD AND MOBILE WIRELESS MONITORING SYSTEM
    Publication number: 20080219193
    Abstract: A wireless network interface card applied with a portable wireless terminal device includes a wireless communication module, a processing module and a connection interface module. The wireless communication module transmits or receives a wireless communication signal having sensing information according to a communication protocol of a personal wireless area network (PWAN). The processing module electrically connected with the wireless communication module receives the sensing information. The connection interface module is electrically connected with the processing module and the portable wireless terminal device. The sensing information is transmitted to the portable wireless terminal device through the processing module and the connection interface module.
