Title: Method and apparatus for measuring the carrier to interference and noise ratio of a logical band using downlink preamble
Inventor: KWAK KI YOUNG
IPC: H04B17/00
Filed: 2005-12-31
Abstract: A carrier to signal and noise ratio measurement device of a logical band using a downlink preamble and a method thereof are provided to easily measure carrier to signal and noise ratios of each logical band by using a preamble, and to perform transition to another logical band or a better channel mode by using the measured ratios, thereby maintaining an optimum channel environment. A preamble symbol obtainer(501) obtains a downlink preamble symbol from a baseband frequency signal in a downlink channel mode area including plural logical bands. A signal estimator(502) estimates a preamble signal and a data signal from the preamble symbol. A power calculator(503) calculates a power value of the estimated data signal, and calculates a power value of a noise signal from the estimated preamble signal and the preamble symbol. A carrier to signal and noise ratio operator(504) calculates a carrier to signal and noise ratio associated with a channel mode by using the power value of the noise signal and the power value of the data signal.

Title: Article identification and tracking using electronic shadows created by rfid tags
Inventor: ECKSTEIN ERIC
IPC: G06K7/08
Filed: 2004-05-18
Abstract: A tracking system uses RFID (radio frequency identification) tag technology to facilitate the identification and tracking of items in an environment through a technique known as shadowing. As an object or target moves within a pre-described detection zone with communicating antenna and RFID sensors, the object or target blocks the line of sight between respective antenna and sensors, preventing electromagnetic coupling between the sensor and the antenna and thus casting an electromagnetic shadow along the line of sight. One approach of this invention uses this shadow technique to perform functions such as theft (shrink) deterrence/ detection; tracking the motion of objects through an environment by monitoring the shadow; and correlation analysis of people shadows to tagged items (e.g., merchandise, articles) to foster marketing and merchandising effectiveness.
