Abstract: The present invention relates to a communication system capable of reducing processing loads imposed on a base station device and a server that sets a timing of a synchronization signal for the base station device. A management server (3) provides notification of a transmission order of the synchronization signal to each of a plurality of base station devices (1).

Abstract: Provided are a radio communication system, a receiver, and a transmitter, which are capable of reducing an operation time period of a reception circuit of the receiver and achieving reduction in power consumption even if there is a clock error between the transmitter and the receiver. In a case of a conventional method illustrated in FIG. 1(A), the receiver is operated earlier by a time period (Tm), to thereby achieve synchronization before the clock error of the receiver exceeds the time period (Tm). This requires an extended reception time period for achieving clock synchronization, which therefore prevents the receiver from reducing its power consumption. In view of this, according to the present invention, as illustrated in FIG. 1(B), a synchronization signal is continuously transmitted from the transmitter a plurality of times in a short period of time, and the receiver receives only one of the continuously-transmitted synchronization signals.

Abstract: A group-basis distribution data presence/absence information generation section generates distribution data presence/absence information indicating whether or not data to be transmitted to a reception device included in a group that includes one or a plurality of reception devices is included in a frame. Further, a synchronization signal generation section generates synchronization information including the distribution data presence/absence information.

Abstract: An ESL server (3) includes a management-device storage unit for storing information indicating a position at which a second electronic shelf label terminal (1) is installed, a management-device reception unit for receiving information transmitted from a transmission unit of a handy terminal (5), and a management-device control unit for identifying a position at which a first electronic shelf label terminal (1) is installed based on information for uniquely identifying the first electronic shelf label terminal (1), information for uniquely identifying the second electronic shelf label terminal (1), information indicating relative position between the position at which the second electronic shelf label terminal (1) is installed and the position at which the first electronic shelf label terminal (1) is installed, and the information indicating the position at which the second electronic shelf label terminal (1) is installed.

Abstract: A biometric information detecting apparatus has a biometric sensor for measuring biometric information for a predetermined time period. An A/D conversion portion acquires a sampling data by subjecting an output of the biometric sensor to A/D conversion. A storing portion stores the sampling data. A frequency analyzing portion subjects the sampling data stored in the storing portion to a frequency analysis and stores a result of the frequency analysis to in storing portion. A biometric state value calculating portion calculates a biometric state value from the result of the frequency analysis stored in the storing portion. An SN ratio calculating portion calculates an SN ratio from the result of the frequency analysis stored in the storing portion. A determining portion determines a reliability of the biometric state value based on whether the calculated SN ratio exceeds a predetermined threshold.

Abstract: Provided is a technology of embedding watermark data into an arbitrarily-shaped region by applying a wavelet transform. Prepared are: image data into which the watermark data is to be embedded; a shape map that defines the arbitrarily-shaped region into which the watermark data is to be embedded within the image data; and the watermark data. An SA-DWT processing unit uses the shape map to recognize a given region included in the arbitrarily-shaped region within the image data, and subjects image data in the given region to the wavelet transform. The wavelet transform causes the image data in the arbitrarily-shaped region to be divided into frequency bands, and a watermark data embedding unit embeds the watermark data into a frequency space of the image data generated by the dividing. An SA-IDWT processing unit subjects the resultant to an inverse wavelet transform, and watermark-embedded image data is generated.

Abstract: The invention relates to an organism information detecting apparatus capable of determining a motion state of a subject when organism information is detected. The organism information detecting apparatus of the invention includes organism information detecting means for detecting organism information of the subject by being brought into contact with the subject by a previously determined sampling time period and outputting an organism signal, organism information data calculating means for calculating an organism information data by processing the organism signal, supplementary data calculating means for calculating an average value of a variation amount per time of a data constituted by digitizing the organism signal as a supplementary data of the organism information data, and data storing means for relating the organism information data and the supplementary data to be stored.

Abstract: The invention relates to a biometric information detecting apparatus for monitoring a state of a living body based on information constituted by adding an auxiliary data capable of determining a measuring state when biometric information is measured to a biometric state value.

Abstract: An organism information measuring device has two light irradiating parts that irradiate light of short and long wavelength, respectively, toward an organism, and two light receiving parts that receive backward scattered light from the organism and produce organism information signals according to the quantity of received light. A data processor determines organism information indicative of a condition of the organism based on the organism information signals. The two light irradiating parts may be combined into a single light irradiating part, with one of the light receiving parts disposed farther from the light irradiating part than the other and having a light receiving area larger in size than that of the other and proportional to the distance thereof from the light irradiating part.

Abstract: A condition monitoring system has a living body information measuring terminal that measures living body information, a living body information receiving terminal for receiving a measurement result and analyzing a condition of a subject, and a monitoring terminal that monitors the condition of the subject. The method of analysis processing performed by the condition monitoring system is changed in response to requests from the subject.

Abstract: A living body information measuring system is capable of accurately determining the originator of living body information data transmitted from living body information detecting devices used by multiple users. Each of the living body information detecting devices is identified by a portable device worn on the user and having a first identification code associated with the user in advance. Then, information on the kind of the living body information detecting device is added to the first identification code to generate a second identification code, and the second identification code is transmitted to the living body information detecting device. The living body information detecting device uses the second identification code as its own identification code and transmits it to a data collector together with the detected living body information data.
