20100065256 | Mechanically compliant thermal spreader with an embedded cooling loop for containing and circulating electrically-conductive liquid - The present invention is a thermal spreader for providing a high effective thermal conductivity between a heat source and a heat sink. The thermal spreader may include a mechanically flexible substrate. The mechanically flexible substrate may be at least partially constructed of organic materials. The mechanically flexible substrate may form an internal channel which is configured for containing an electrically-conductive liquid. The thermal spreader may further include a pump. The pump may be configured for being connected to the substrate and for circulating the electrically-conductive liquid within the internal channel. The thermal spreader may further include one or more thermally-conductive, rigid metal inserts. Each insert may be configured for being in thermal contact with the electrically-conductive liquid and the substrate and for promoting heat transfer between the thermal spreader and the electrically-conductive liquid. | 03-18-2010 |

20090052105 | Thermal Management within Mobile RFID Readers through the Application of Temperature Governed Variable Non-Emissive Intervals - A thermal management system and method to control temperature in an RFID reader is described herein. In particular, by inserting variable periods of inactivity (or latency) at the beginning or at the end of each read cycle, proportional to an instantaneous temperature value of the RFID reader, over-heating and damage of RFID reader electronics is prevented. The RFID reader includes a thermal sensor and determines when the high power RF electronics is enabled. If the RFID reader is in an over-heated condition, it can be turned OFF and during this period any requests received on an interface to the RFID reader to perform a read of tag(s) are not processed. | 02-26-2009 |
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 |
