Battery powered wireless transceiver having LPRF component and second wake up receiver
First Claim
1. A wireless transceiver, comprising:
- (a) a low power radio frequency (LPRF) communications component capable of powering down to conserve energy and capable of powering up in response to an electronic signal, the LPRF communications component including a transmitter and a first receiver; and
(b) a second receiver that is configured to screen a radio frequency broadcast and provide, on the basis of specific data identified therein, the electronic signal to the LPRF communications component in order to power up the LPRF communications component;
(c) wherein said second receiver is adapted to draw less current than the LPRF communications component while awaiting receipt of and listening for a radio frequency broadcast; and
(d) wherein the wireless transceiver includes an energy source.

Abstract
A wireless transceiver includes a low power radio frequency (LPRF) component that powers down to conserve energy and powers up in response to a signal; and a second receiver that provides the signal in response to receipt of a radio frequency broadcast. The broadcast is targeted to activate particular transceivers by including, in the broadcasts, identifications such as class designations, in which case the transceivers power up and form networks. A transceiver may include one or more identifications and may include a unique identification of the transceiver itself. The LPRF component may be a Bluetooth radio, but the overall transceiver itself only draws about 10 to 15 μA while actively awaiting and screening for a targeted broadcast.
