20080224833IC MEMORY, INFORMATION COMMUNICATION APPARATUS, AND INFORMATION MANAGEMENT SYSTEM - An information management system comprises information processing unit 09-18-2008
20080262770INFORMATION RECORDING MEDIUM, AND PROCESS MANAGEMENT APPARATUS AND PROCESS MANAGEMENT SYSTEM USING THE INFORMATION RECORDING MEDIUM - Apparatuses and method capable of reliably tracking processes through which products have passed without calling for expensive setup are necessary in production and distribution processes of the products. A process management apparatus including a data transmission/reception unit to and from an RFID tag of an information recording medium and a data generation unit comprises a process data generation unit for representing a process, a process pass certificate data generation unit for generating process data pass certificate data and a transmission/reception unit for the process data with the information recording medium and the process pass certificate data can track the processes through which the object products have passed.10-23-2008
20090008444PORTABLE TERMINAL - A management apparatus including a portable terminal identifying module to receive card information from a non-contact IC card processing unit having a module to communicate with an IC card without contact.01-08-2009
20090064296COMMUNICATION SYSTEM, METHOD FOR TRANSFERRING INFORMATION, AND INFORMATION-COMMUNICATION DEVICE - A first information-communication device generates first biometric pattern used for comparison based on user biometric information retrieved by a biometric sensor, and sends the generated first biometric pattern to a second biometric information-communication device. The second information-communication device compares the first biometric pattern sent from the first information-communication device with second biometric pattern, which is user biometric pattern stored in memory, and sends the second biometric pattern to the first information-communication device when the compared biometric pattern matches. The first information-communication device then stores the second biometric pattern sent from the second information-communication device.03-05-2009
20100085150Semiconductor Element, Biometric Authentication Method, Biometric Authentication System and Mobile Terminal - A semiconductor element or mobile terminal stores a user's biometric information pattern used for execution of a biometric authentication process and the residual number of trials indicating the number of allowed failures in the biometric authentication process, sends processing data to an external device so that the external device can use the processing data when the external device executes part of the biometric authentication process, and decreases the residual number of trials by a predetermined value while the processing data is output to the external device after start of communication with the external device.04-08-2010
20100117791Biometric Authentication Method, Biometric Authentication System, IC Card, and Terminal - A biometric authentication system 05-13-2010
20100266121IC CHIP AND INFORMATION PROCESSING APPARATUS MOUNTING IC CHIP - An IC chip includes: a first memory which stores a control program for executing cryptographic processing; a second memory which stores an application; an arithmetic processor which receives first data including at least part of a cryptographic private key stored in a predetermined area of the application, and executes the cryptographic processing in accordance with the control program; and an auxiliary arithmetic processor which executes predetermined arithmetic processing under control of the arithmetic processor. If the first data does not match a data format defined by a software interface of the auxiliary arithmetic processor, the arithmetic processor controls to generate second data by processing the first data so as to match the data format, and to store the generated second data in a data table provided in the second memory.10-21-2010

Patent application numberDescriptionPublished
20090228727METHOD AND PROGRAM FOR SETTING MICROPROCESSOR POWER SUPPLY VOLTAGE - A determining unit determines the state of the microprocessor. A setting unit sets a power supply voltage to be supplied to the microprocessor according to the state of the microprocessor determined by the determining unit. A power supply circuit supplies the power supply voltage set by the setting unit, to the microprocessor via a power supply line. The determining unit determines repeatedly the state of the microprocessor at preset timing, and the setting unit resets the power supply voltage every time the determination is performed by the determining unit.09-10-2009

20090112550System and Method for Generating a Worst Case Current Waveform for Testing of Integrated Circuit Devices - A system and method for generating a worst case current waveform for testing of integrated circuit devices are provided. Architectural analysis of an integrated circuit device is first performed to determine an initial worst case power workload to be applied to the integrated circuit device. Thereafter, the derived worst case power workload is applied to a model and is simulated to generate a worst case current waveform that is input to an electrical model of the integrated circuit device to generate a worst case noise budget value. The worst case noise budget value is then compared to measured noise from application of the worst case power workload to a hardware implemented integrated circuit device. The worst case current waveform may be selected for future testing of integrated circuit devices or modifications to the simulation models may be performed and the process repeated based on the results of the comparison.04-30-2009
