Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may send a special fast read command to the tag which includes a read request and communications control parameters including the number of time slots for transponder communications, the number of transmissions that an individual transponder is allowed to issue, and the data rate at which the reader communicates to the transponder. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment. Additional schemes are provided to halve the number of active tags in each transmission cycle and to selectively inactivate designated groupings of tag, thereby improving discrimination of the tags in the interrogation field. The tags may be selectively placed in either a tag-talk-first mode or a reader-talk-first mode.

A device for detecting the position of a human finger or other object on a touch-sensitive scrolling pad. Dual independent oscillators may be used to generate two pulse trains at frequencies dependent upon the capacitance of two conductors resulting from the position of the finger on the conductors. The pulses from each oscillator may be counted over a time interval. A ratio-metric measurement may be taken by calculating the ratio of the two counts, and a sum may also be calculated. The ratio of the two counts relates to finger position on the device, and their sum relates to finger pressure upon the device.

A method for issuing tickets proceeds by selecting an inactive ticket that includes an identifier. Payment is provided for the ticket, and the identifier and a payment amount is entered into a payment processing device. The identifier is transmitted to a host computer system having a record of the identifier and a status of the ticket. The status of the ticket is then changed to an active status in the host computer system.

Disclosed is a method of capturing and reading a pattern image having three or more pages generated from predetermined information using a capturing section provided in a reading apparatus. The pattern image is configured such that each page includes relevant page information indicating a position of the relevant page and the pages are displayed on a display screen sequentially and successively at a time interval and cyclically and repetitively. The method includes a step of, when two pages of the pattern image have been read, causing the reading apparatus to predict a capturing timing by the capturing section for each remaining unread page from a capturing time interval between the two pages and the relevant page information of each of the two pages, and to perform control such that each remaining unread page of the pattern image is captured and read by the capturing section with the predicted capturing timing.

Circuits and methods for providing an SRAM or CAM bit cell. In one embodiment, a bit cell portion with thicker gate oxides in the storage cell transistors, and thinner gate oxides in a read port section having transistors are disclosed. The use of the thick gate oxides in the storage cell transistors provides a stable storage of data and lower standby leakage current.

An image synthesis method includes a placement information obtaining step of obtaining placement information about a plurality of images in which adjacent images have a common subject region, and a synthesis step of combining the images using a mapping mode in accordance with the placement information. Prior to performing mapping transformation of the input images, coordinate-space transformation parameters for transforming the coordinate space of one image among the images into the coordinate space of another image are generated. The images are combined based on a given mapping mode and the coordinate-space transformation parameters.

Three-, and four-dimensional ("3-D" and "4-D") volume radiation memories store multiple binary bits of information-typically about five to ten and more typically eight such bits-in the same physical volumes on several different photochromic chemicals co-located in the volume. Each of the multiple photochromic chemicals is individually selectively written with an individually associated pair of radiation beams of an appropriate combined frequency-i.e., a "color"-and energy by a process of two-photon ("2-P") absorption. All the multiple information bits that are stored within all the photochromic chemicals in each addressable domain are read in common, and induced to simultaneously fluoresce, again by process of 2-P absorption. The fluorescence of each of different photochromic chemical in each addressed domain-which fluorescence is selective in accordance with the written state of each such photochromic chemical-is separated from, and is separately detected from, the fluorescence of all other photochromic chemicals because it is of a unique color, and is spatially steered to an associated detector array, normally a Charge Coupled Device (CCD), by a monochromator, normally a prism. Exemplary fluorescent photochromic chemicals are spirobenzopyran, rhodamine, cumarin and anthracene. Suitable groups of photochromic chemicals are formed from individual photochromic chemicals exhibiting narrow, sharp, separate spectra of absorption and of emission suitably distinct from each other, and where no chemical's fluorescent emission energy overlaps the absorption energies of any other chemicals.
