Network navigation method for printed articles by using embedded codes for article-associated links

Abstract: A network navigation method includes steps of reading a first code (24) from an object (12), communicating a portion of the first code (24) to a first database (54), receiving translation information from the first database (54) to associate a plurality of electronic addresses with a plurality of codes (24, 26, 30) including the first code (24), and translating the first code (24) to a first electronic address using the translation information. A network navigation system is provided to perform the aforementioned steps.

Method and apparatus for selectively activating radio frequency identification tags that are in close proximity

Abstract: A radio frequency identification exciter ( 200 ) includes a plurality of antenna elements ( 122 a-i ) that are spaced to define active areas ( 130 a-e ). A matrix switch ( 202 ) flexibly connects the plurality of antenna elements to an exciter circuit ( 203 ). Independent switches ( 204 a-i ) are selectively switched such that an electric field is generated between at least two antenna elements whereby radio frequency identification tags ( 132 ) in the vicinity of the two antenna elements are capacitively powered to exchange data with the exciter. Antenna elements other than the at least two antenna elements may be selectively coupled to a signal from the exciter circuit that inhibits activation of radio frequency identification tags in the vicinity of those antenna elements. The matrix switch preferably comprises polymer-based circuits.

Method for controlling the level of oxygen stored by a catalyst within a catalytic converter

Abstract: The catalyst control method of the invention continuously estimates a level of oxygen stored by a catalyst within a catalytic converter The estimated oxygen stored by the catalyst is compared to a predetermined threshold and positive or negative deviations in the oxygen amount from the threshold is determined When a positive deviation from the threshold amount is detected, the air/fuel ratio flowing into an engine (16) is decreased Correspondingly, when a negative deviation is detected, the air/fuel ratio flowing into the engine (16) is increased The amount of oxygen stored by the catalyst is determined by analyzing signals from a first gas sensor (28) positioned upstream from a catalytic converter (34) and a second gas sensor (30) positioned downstream from the catalytic converter (34) An engine control unit (10) integrates an expression for the mass flow rate of excess oxygen into the catalytic converter (34) Engine control unit (10) applies a change in air/fuel ratio to maintain the oxygen level on the catalyst within the catalytic converter (34) at a desired level

Satellite positioning system receiver with reference oscillator circuit and methods therefor

Abstract: A method in a location enabled mobile wireless receiver having an oscillator, including determining a change in cellular network based frequency error of the oscillator (250), based on a difference (230) between a cellular network based frequency error of the oscillator and a reference cellular network based frequency error (210) of the oscillator, determining a first frequency error of the oscillator by summing (250) a reference satellite positioning system receiver based oscillator frequency error (220) with the change in cellular network based frequency error of the oscillator.

Automatic new radiotelephone system registration notification

Abstract: A process for use in a radiotelephone that has multiple telephone numbers for use in different cellular radiotelephone systems. The numbers are stored in number assignment modules (NAM's) with its corresponding system identification code. The process compares a received system identification code with the ones in memory (103). If a match is found, the radiotelephone user is prompted to select the new telephone number (104). If the new number is not selected or the identification code is not found in memory, the radiotelephone becomes a roaming unit and enters an idle state (107) waiting for an incoming call.
