Abstract: A wireless communication device stores correspondence information that associates a plurality of operation modes previously selected for communication with a plurality of sender communication devices, with a plurality of identification information items of the sender communication devices. For data transmission to a destination communication device, the wireless communication device selects an operation mode that is previously selected for communication with the destination communication device using the correspondence information.

Abstract: A data communication apparatus includes an antenna, an analog front-end circuit, and a controller. The analog front-end circuit is connected between the antenna and the controller and includes first and second modulators, a driver, a demodulator, and an input switch. The first modulator modulates data to be transmitted to a read-write device as a response to a request from said read-write device and sends the modulated data to the antenna. The second modulation circuit modulates data to be transmitted to other ID tags. The driver amplifies an output from the second modulator to drive the antenna. The demodulator demodulates data sent from the other ID tags and ID-tag read-write devices. The input switch selectively inputs the data to the first or second modulator. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: An ID tag reader/writer for writing and reading data in and from one or more ID tags is provided. The ID tag reader/writer includes (a) one or more antennas configured to perform radio communications with the ID tags, (b) one or more analog frontend units, each unit being provided for one of the antennas, configured to generate a carrier wave based on a clock signal and to perform signal modulation and demodulation, and (c) a controller configured to generate and output the clock signal to the analog frontend units and select one of the analog frontend units corresponding to a target ID tag to which data are to be transmitted, wherein the controller performs data transmission to and from the analog frontend units using digital signals.

Abstract: A reader/writer device is disclosed that comprises plural channels corresponding to plural ID tags, and a controller that sends and receives data to and from the channels. Each of the channels includes an antenna unit and a modulation/demodulation unit that support a communications specification that the corresponding ID tag is compliant with. The controller enables communications according to the communications specification that the ID tag, which the data are to be sent to or received from, is compliant with.

Abstract: A disclosed communication device includes a controller that outputs a signal; an antenna that transmits a radio wave which corresponds to the signal output from the controller and also outputs a signal which corresponds to a received radio wave to the controller; a first function that receives a signal, which responds to a first radio wave transmitted from the antenna, at the antenna; a second function that receives a second radio wave transmitted from another communication device at the antenna and also returns a signal output from the controller in response to the second radio wave from the antenna; and a unit that prevents the execution of the second function while the first function is being executed and prevents the execution of the first function while the second function is being executed.

Abstract: A speech recognition apparatus includes an input unit, a pattern generator, a speaker-independent dictionary for storing a first group of reference patterns, and a speaker-dependent dictionary for storing a second group of reference patterns. The apparatus also includes a dictionary information storing unit which stores dictionary information about the first group of reference patterns and the second group of reference patterns, and a weighting unit which calculates a weighting factor from the dictionary information and which weights the second group of reference patterns in the speaker-dependent dictionary by using the weighting factor to thereby output weighted reference patterns.
