Abstract: A system and method of providing system integrity and audit capabilities to a positive identification system is disclosed. In the preferred embodiment, the system uses biometric access authority information units and a biometric comparison system at a remote database site to permit authorized system users to access the positive identification system. The system also utilizes secondary access authority information units to permit authorized system users to access the system in the event that one or more authorized system users cannot be authenticated using the biometric comparison system.

Abstract: An electronic door unlocking system comprising an electromagnet within a door adjacent to a deadbolt to retract the deadbolt upon energization of the electromagnet and an associated spring to advance the deadbolt into locking orientation with the recess upon a deactivation of the electromagnet.

Abstract: A radio selective calling receiver which allows anybody to read characters easily which disappear when a message is scrolled up on a screen by means of a simple display. A control circuit 2 is used to scroll the message displayed on the screen vertically in units of a dot and to switch characters on a line which gradually disappear due to the scrolling to a simple display which can be recognized as characters at the point when they cannot be recognized as characters, based on a switch operation of a switching circuit 5.

Abstract: A financial transaction customer carries a card key containing a unique, machine-readable code. The code is an encrypted data set representing the user's thumbprint. A scanning system senses the user's thumbprint on or adjacent the card key as he turns the card key in a keyhole. The code and thumbprint are read by laser and must match previously recorded data before an indication of satisfactory identification can be returned. The identification system further includes a centralized database containing data and processing software for recognizing the encoded card keys of the system, in addition to data and processing software for authenticating a user's thumbprint. A network links this centralized database to a number of remote terminals at sites where identification is required. Such a distributed network is common in today's identification systems involving more than one remote site.

Abstract: A transponder has a memory, a data processor, a transmit memory and a transmission circuit. The memory stores data. In a transmit mode of the transponder, the data processor is operable in a normal-energy mode and an energy-saving mode. When the data processor is in the normal-energy mode, the data processor retrieves the data from the memory and processes the data, and the processed data is stored in the transmit memory. Thereafter, the data processor is controlled from the normal-energy mode to the energy-saving mode, and the transmission circuit reads out the stored processed data from said transmit memory and transmits the read out stored processed data to a base station. Transponder for transmitting processed data to a base station over large distances and at a high data transfer rate.

Abstract: A system and method of installing and removing shelf talkers which works in connection with electronic price labels. The system includes a bar code reader for reading first bar code labels of first items following installation of first shelf talkers, second bar code labels of a number of second items having second shelf talkers already installed, third bar code labels of third items following removal of third shelf talkers, and fourth bar code labels of a number of fourth items having fourth shelf talkers already removed, and for transmitting bar code information for the first, second, third, and fourth bar code labels and errors for the second and fourth items. The system further includes a computer for generating a list of the items including the first and second shelf talkers to be installed and the third and fourth shelf talkers to be removed, and for generating a report identifying placement of the first and second shelf talkers for the first and second items and the errors.

Abstract: A method of user-transparent auto re-synchronization for a remote keyless entry system includes assigning a default challenge-count window (101). A first data packet including a first transmitter-side symbolic count (103) and a first command code is transmitted by a transmitter (200) and authenticated by a receiver (250). An auto-synchronization challenge-count window is assigned when the first transmitter-side symbolic count (103) is not bounded within the challenge-count window (109). A second data packet including a second transmitter-side symbolic count (103) and a second command code is transmitted by the transmitter (200) and authenticated by the receiver (250). The challenge-count window is returned to the default challenge-count window, when the second transmitter-side symbolic count is bounded within the auto-synchronization challenge-count window and the receiver-side symbolic count (123). Then the second command code is executed (127).

Abstract: A system for locating lost keys or other items includes a compact, pocket-sized unit that includes a key chain. The unit includes a sound generator that generates a sound of sufficient volume to facilitate locating the device from a distance. The sound generator is coupled to a beeper circuit to allow the operator to actuate the sound generator by placing a telephone call to a beeper or other service. The unit also acts as a conventional beeper for allowing the user to receive messages. Herein, a beeper is defined to include pagers and any other portable device that can be activated by a user placing a telephone call. Using a voice menu, the caller can control the volume of the audible signal generated by the sound generator and/or the duration of the sound-generation event. The operator can also activate a flashing light of the compact unit.

Abstract: A selectively called radio receiver is arranged by a receiving unit for receiving a radio selection signal, an operation unit for accepting an operation, a storage unit for storing a control program, and a processing unit for processing the reception information derived from the receiving unit and the operation information outputted from the operation unit in accordance with the control program stored in the storage unit. This selectively called radio receiver is further arranged by a notifying unit for producing notification information based on the processing information outputted from the processing unit, and a monitoring unit for monitoring an access condition by the processing unit to the storage unit. Even when the processing unit is erroneously operated, increasing of power consumption can be suppressed, and the reliability of this selectively called radio receiver can be improved.

Abstract: A pager which does not delete or rewrite received messages can be produced at such a low cost that it is viable as a disposable pager. Messages are stored sequentially as they are received, packed in memory end-to-end, so that memory efficiency is maximized. No complex memory management is required, minimizing production costs. If memory is full or near-full when a new message is received, either the message is displayed and not stored, or receipt of the new message is refused. By using removable, nonvolatile memory modules, the pager unit can be reused, while enabling old messages to be externally archived for indefinite periods of time.

Abstract: In a communication system comprising a base station and a plurality of asynchronously operating remote units, a method of communication between the base station and each of the remote units includes each remote unit randomly transmitting a first bit pattern to the base unit. Upon detecting the reception of an error-free bit pattern, the base unit transmits an ACK during a first window of time. The remote unit which detects the ACK during a corresponding first window of time becomes the selected unit and thereafter communicates with the base station. All other remote units continue monitoring for the transmission of a command belonging to a first set of commands, afterwhich the selected unit goes into a quiet mode and the unselected units resume their random transmissions of the first bit pattern to the base unit.
