  • Publication number: 20130250845
    Abstract: In some embodiments an apparatus includes a wireless sensor configured to be operatively coupled to a network gateway device that is configured to receive one of a first data packet or a second packet from the wireless sensor. The wireless sensor is configured to send the first data packet at a first time on a first frequency, the first data packet including a payload associated with a value of a measurement that was measured by the wireless sensor. The wireless sensor is configured to send the second data packet at a second time on a second frequency, the second data packet includes a payload associated with the value.

  • Patent number: 8461817
    Abstract: An apparatus includes a first converter module, a second converter module, and a sensor module. The first converter module converts a wireless power associated with an electromagnetic wave to a first DC voltage. The first converter module can include, for example, a Villiard cascade voltage multiplier, a precision rectifier, or a full-wave bridge rectifier. The sensor module monitors the first DC voltage. The second converter module converts the first DC voltage to a second DC voltage that is larger than the first DC voltage. The second converter module is enabled by the sensor module when the first DC voltage is above a first threshold voltage. The second converter module is disabled by the sensor module when the first DC voltage is below a second threshold voltage that is lower than the first threshold voltage. The second converter module provides power to a load based on the second DC voltage.

  • Publication number: 20120316414
    Abstract: In some embodiments, a personal area network (PAN) includes a mobile transmitter (e.g., a mobile or cellular phone) and one or more devices (e.g., sensors) that require power to operate (e.g., collect data). The mobile transmitter can be configured to transmit a sufficient amount of power (e.g., RF energy) to the one or more devices to power the one or more local devices. In addition to transmitting power, the mobile transmitter can be configured to communicate over a wireless network (e.g., a cellular network) as its primary function.
