REMOTE SENSOR INTERFACE (RSI) STEPPED WAKE-UP SEQUENCE
First Claim
1. A wireless transceiver, comprising:
- (a) a two-way wireless communication component capable of powering down to conserve energy and capable of powering up in response to an electronic signal, the two-way wireless communication component including a transmitter and a first receiver; and
(b) a second receiver that is configured to screen a radio frequency broadcast and provide the electronic signal to the two-way wireless communication component in order to power up the two-way wireless communication component, the second receiver configured to;
(i) screen the radio frequency broadcast for first criteria, wherein the wireless transceiver draws a first electric current when screening the radio frequency broadcast for the first criteria, and (ii) screen the radio frequency broadcast for second criteria, wherein the wireless transceiver draws a second electric current when screening the radio frequency broadcast for the second criteria, the second electric current being an order of magnitude larger than the first electric current;
(c) wherein the second receiver is adapted to draw substantially less current while awaiting receipt of and listening for a radio frequency broadcast than the current that the two-way wireless communication component would draw while awaiting receipt of and listening for a radio frequency broadcast.

Abstract
A transceiver includes a two-way communication component capable of powering down to conserve energy and capable of powering up in response to an electronic signal, the two-way communication component including a transmitter and a first receiver; and a second receiver that is configured to screen a radio frequency broadcast and provide the electronic signal to the two-way communication component in order to power up the two-way wireless communication component. The second receiver is configured to screen the radio frequency broadcast for first criteria, and screen the radio frequency broadcast for second criteria. The electric current may be an order of magnitude larger when screening for the first criteria than the second criteria. Screening also may be performed for third criteria, namely, specific data. The second receiver is adapted to draw substantially less current while awaiting receipt of and listening for a radio frequency broadcast than the two-way wireless communication component.
