Abstract: An electronically-controlled locker system that utilizes distributing processing to control access to, and assignment of, a plurality of lockers in a school, workplace, fitness center, etc. The system uses a plurality of locker control units that control access to a corresponding set of lockers based on user inputs and on user/locker authorization data that is provided from a central administrator workstation. This administrator workstation communicates with a system control unit that is in communication with every locker control unit and which allows cross-communication between locker control units.

Abstract: An on-vehicle apparatus communicates with an electronic key by wireless communication. The one-vehicle apparatus decides to unlock a vehicular door according to an identification result between first ID of the electronic key and unlock-operation ID of the on-vehicle apparatus, and decides to start an engine of the vehicle according to an identification result between second ID of the electronic key and engine-starting ID of the on-vehicle apparatus. The on-vehicle apparatus commands the electronic key to output third ID shorter in data length than the second ID, when the first ID corresponds with the unlock-operation ID. The on-vehicle apparatus permits starting the engine when the third ID corresponds with compacted data of the engine-starting ID.

Abstract: A transponder identification system comprising a plurality of transponders and an interrogation device arranged to identify each of the transponders by transmitting successive interrogation signals according to a systematic search strategy, wherein the search is truncated where the interrogation device receives fewer than a predetermined number of different responses from the transponders, to a transmitted interrogation signal.

Abstract: An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

Abstract: An identification system in which a trigger signal, emitted on an object side and received by a portable code generator, is provided. The trigger signal is used on the object side to phase code a reference signal. The code generator encodes a response signal using the trigger signal in a phase-coded manner and retransmits the response signal. The received response signal is compared with the generated reference signal in an object-side evaluation unit using an autocorrelation function. If the value of the autocorrelation function is larger than a threshold value, an enabling signal is generated.

Abstract: A combined immobilizing and steering column control system for a vehicle includes a device, a steering wheel, and a vehicle immobilizing system. The device has a transponder for transmitting an identification signal. The steering wheel includes controls and a first inductor. The first inductor transmits a control signal for controlling a vehicle function in response to a corresponding steering wheel control being actuated. The immobilizing system has a second inductor and a controller. The second inductor is operable to sense the identification signal transmitted by the transponder and to sense a control signal transmitted by the first inductor. The controller performs a vehicle immobilizing function in response to the second inductor sensing an identification signal transmitted by the transponder. The controller enables the vehicle function corresponding to an actuated steering wheel control in response to the second inductor sensing the corresponding control signal transmitted by the first inductor.

Abstract: A system and method for controlling remotely controlled components of a plurality of vehicles in response to a short range common signal emitted by a transmitter that can operate the components only during specified time periods. A transmitter can be programmed to provide a relatively long range customer signal that can operate the components at any time. The system and method are operative on a mutually exclusive basis wherein the remotely controlled components only respond to the common signal or the customer signal.

Abstract: A transponder 14.1 for a radio frequency (RF) identification system comprises an antenna 22.1 having an antenna impedance (ZA) having a real part (RA) connected to transponder circuitry presenting a load impedance (ZL) having a real part (RL), a ratio ( R L R A ) of the real part (RL) of the load impedance and the real part (RA) of the antenna impedance having a first value that is bigger than one when the transponder is not transmitting data. During transmission of data the ratio is switched between the first value and a second smaller value.

Abstract: Voice control systems are used in diverse technical fields. In this case, the spoken words are detected by one or more microphones and then fed to a speech recognition system. In order to enable voice control even from a relatively great distance, the voice signal must be separated from interfering background signals. This can be effected by spatial separation using microphone arrays comprising two or more microphones. In this case, it is advantageous for the individual microphones of the microphone array to be distributed spatially over the greatest possible distance. In an individual consumer electronics appliance, however, the distances between the individual microphones are limited on account of the dimensions of the appliance.

For determining the body fat of a user to be examined, the body fat meter equipped television remote controller registers the physical data including the weight and the height of the user, measures the impedance across the body of the user, and transmits to a television receiver a body fat measurement signal which carries the physical data and the impedance measurement. The television receiver calculates the body fat of the user from the physical data and the impedance measurement carried on the body fat measurement signal and displays a resultant calculation of the body fat on its display provided for displaying images of the existing television broadcasting.

Abstract: An oscillating valve driven by the pressure in a mud pulser develops a pressure variation in the mud pulse signal that is at a frequency that is different than the frequencies of the mud system. The oscillating valve is coupled to or integral with the pulse drive cylinder, whether the drive means for operation of the pulser is upstream or downstream from the orifice, or whether or not the drive means and the poppet are on the same side or opposite sides of the orifice. The oscillating valve is a bistable valve which preferably forms one wall of the drive piston of the pulser. Pressure from the drive cylinder behind the drive piston is directed in such a way as to unseat the bistable valve. When the bistable valve unseats, pressure is bled from within the drive cylinder, which also bleeds the pressure that unseated the bistable valve in the first place.

Abstract: A data transmission system using a human body as a signal transmission path includes a transmitter and a receiver. The transmitter uses a pair of electrodes which are held in close proximity to the skin of the human body. The transmitter transmits data to the receiver through the signal transmission path partly extending through the human body when a user carrying the transmitter touches a touch electrode of the receiver. The electrodes are integrated into a garment worn by the user in such a manner that the electrodes are kept in a closely facing relation to the skin of the user, thereby establishing the electrical path extending through the human body. With the integration of the two electrodes into the garment, the user wearing the garment as an everyday clothes or uniform can be easy and convenient to carry the transmitter for successful transmission of the data.
