| 20110019824 | LOW POWER RADIOFREQUENCY (RF) COMMUNICATION SYSTEMS FOR SECURE WIRELESS PATCH INITIALIZATION AND METHODS OF USE - Provided herein is a wireless healthcare system comprising at least one sensor and a base unit adaptable to be in communication with the sensor. The sensor can be is adaptable to communicate with the base unit at a first power during formation of a communication link and is further adaptable to communicate with the base unit at a second power after the communication link has been formed, and wherein the sensor and base unit are components of a wireless healthcare system. The sensor can be a patch adaptable to be positioned on the surface of a patient. Further provided herein is a method of using the wireless healthcare system and kit. | 01-27-2011 |
| 20090042527 | DYNAMIC LOW POWER RECEIVER - The present invention comprises a dynamic front end radio receiver that determines the current operating conditions and adjusts the power consumption of the receiver accordingly. In one embodiment, the receiver can detect the strength of an incoming signal and the presence of any interfering signals. The receiver includes a series of programmable blocks, where the bias of each block is adjustable. The power consumption of the overall receiver can be minimized by controlling each programmable block with a control signal. Thus, the receiver can contend with a dynamic environment, so that the performance is controlled in a manner sufficient to process the incoming signal and minimize the power dissipation necessary to achieve acceptable radio performance. An embodiment of the invention may be used in wireless radio networks for a variety of applications, such as healthcare wireless technology. | 02-12-2009 |
| 20090040107 | SMART ANTENNA SUBSYSTEM - The present invention provides several smart antenna devices and methods. The devices and methods incorporate a programmable delay element into each RF pathway, which enables smart antennas to receive not only narrow band signals but also ultra-wide band signals at low cost and low power consumption, while in a highly reliable fashion. The devices and methods therefore enable a low complexity smart antenna receiver as part of a highly reliable, low cost and low power sensor network. | 02-12-2009 |
