| 20090146784 | Method and System for Variable Power Amplifier Bias in RFID Transceivers - Described are a method, a device, and a system managing power usage. The method includes operating a communication device in a first state, transmitting a forward signal to at least one target, switching from the first state to a second state, and receiving a reverse signal from the at least one target while operating in the second state. The device, operating in at least a first state and a second state, includes a control circuit switching the device from the first state to the second state, an amplifier operating at a current level coordinated with one of the first state and the second state, and an antenna transmitting a forward signal to at least one target while the device operates in the first state and receiving a reverse signal from the at least one target while the device operates in the second state. | 06-11-2009 |
| 20100302007 | METHODS AND APPARATUS FOR RFID READER CABLE CALIBRATION - A method for calibrating an RFID reader having a transmit port and a receive port includes connecting a cable between the transmit port and the receive port, transmitting a known signal from the transmit port to the receive port through the cable, and computing a cable loss associated with the cable based on the difference between the known signal and the signal detected at the receive port. The power level of the transmit port may then be adjusted in accordance with the cable loss and a known antenna gain. | 12-02-2010 |
