Abstract: A locating system and method employs a plurality of radio frequency readers arrayed with respect to a region having a plurality of zones within which a plurality of radio frequency tags are to be located. Each reader identifies those tags present within its coverage area. The coverage areas of all the readers taken together substantially cover the region and at least part of the coverage area of each reader overlaps at least part of the coverage area of at least one other reader. A data processor receives the identification of the tags within the coverage area of each reader and applies a set of locating rules to determine therefrom in which zone within the region each identified tag is located.

Abstract: The object of the invention is to provide a two-stage pressure atomizer nozzle for at least one liquid to be atomized, with which two-stage pressure atomizer nozzle improved liquid distribution in the exterior space of the pressure atomizer nozzle, in particular improved fuel distribution in a premix burner, can be achieved. To this end, the pressure atomizer nozzle has a nozzle head (4) connecting the outer and inner tubes (2, 3) to one another downstream. At least two separate turbulence and/or swirl chambers (9, 10, 11, 12) are arranged in the nozzle head (4). Each of these turbulence and/or swirl chambers (9, 10, 11, 12) is connected to the second feed passage (6) via at least one swirl passage (16), to the first feed passage (5) via at least one turbulence-generator passage (15) and to the exterior space (18) of the nozzle body (1) via a discharge opening (17).

Abstract: A vehicle information system including a tag system mounted in a vehicle. The tag system transmits vehicle-related data acquired from the vehicle to an interrogator. The vehicle information system utilizes a bus in the vehicle with low-cost RF communications in the tag system and an interrogator to remotely access the vehicle-related data as the vehicle exits or enters a designated area. The interrogator provides the vehicle-related data acquired from the tag system to a host computer.

Abstract: Apparatus, and a concomitant method of operation for the apparatus, for responding to an interrogation signal transmitted by a remotely located interrogator comprising: a demodulator for demodulating the interrogation signal; a signal processor, coupled to the demodulator, for interpreting a set up instruction contained in the interrogation signal and for initiating a counter to count cycles of a carrier wave signal contained in the interrogation signal; and a modulator, coupled to the signal processor, for transmitting a pulse when the signal processor indicates that the counter has attained a count value that matches a codeword stored in the signal processor.
