Abstract: An electronic seal stamp and an electronic sheet are used. The electronic seal stamp has a stamp surface, and has a storing function and output function for electronic information. The electronic sheet is of a sheet shape, has a surface capable of being impressed, and has a storing function and input function for electronic information. When the electronic seal stamp is impressed on the electronic sheet, a seal image on the stamp surface of the electronic seal stamp is transferred to the surface of the electronic sheet. At the same time, the electronic information stored in the storing function of the electronic seal stamp is transferred to the storing function of the electronic sheet, through the output function of the electronic seal stamp and the input function of the electronic sheet. Thus, an electronic seal stamp system, in which both impression of the stamp surface and electronic sealing are possible, is realized.

Abstract: A synchronization circuit modulates a data signal with an amplitude shift keying (ASK) modulation method using an ASK modulation signal to output a modulated signal under the condition that the ASK modulation system and data signal are synchronized with each other. A drive circuit executes a push-pull operation based on the modulated signal and a resonance circuit resonates, under the push-pull operation of the drive circuit, to transmit a transmission signal in a radio wave. The synchronous signal controls a switching device to cut off a connection between the resonance circuit and the ground in synchronization with the modulated signal. Thereby, the transmission signal is generated sharply in the signal transmitter.

Abstract: In a remote keyless system, a fob is disclosed, which provides the user with selective control of elements in a property in concert with a controller at the property, while the fob is nearby the property. In one example the fob is a wireless portable terminal, which accepts a biometric information having been presented by a user. A transducer generates a digital data based on the biometric information. A data store receives and stores the digital data generated by the transducer. A transmitter is responsive to the digital data having been stored in the data store for broadcasting a signal, at a predetermined frequency and modulated by the stored digital data for reception by the controller, after an interval of time corresponding to a time for the user carrying the wireless portable terminal to have traveled a distance, such that the user may present a predetermined biometric characteristic at a convenient place and time prior to the time of a consequent effect thereof at said property.

Abstract: A system reduces the risk of eavesdropping on data used to access an establishment's computer network. The system comprises a personal area network (PAN) access device that couples a low power, low frequency modulated signal to a wearer and a personal area network receiver for receiving the modulated signal. The personal area network access device includes a personal data storage unit and a low power data modulator. The low power data modulator modulates a low power, low frequency signal with the data from the storage unit. This signal is capacitively coupled to the wearer's body so it may be emitted to a PAN receiver. When the wearer brings a body part such as a finger in proximity to or in contact with the PAN receiver, the receiver may receive the modulated signal. The signal may then be demodulated to obtain the user data so it may be encoded in data messages provided to a server of an establishment computer system.
