摘要： A battery powered vehicle tire pressure sensor system has a power saving unit which controls the application of electrical power to the system as a function of tire speed to prolong battery life. The power saving unit has a power control switch which is responsive to tire angular speed. Each sensor assembly of the system is mounted on or in the side wall of a pneumatic tire to generate signals representative of tire pressure whenever power is applied. A processor periodically samples the signals. When the processor determines that the tire pressure is outside a safe range, an r.f. generator is activated by the processor to generate an unsafe tire pressure signal. This signal is converted by a receiver to a warning for the driver.

摘要： An RFID tag having an rfid integrated circuit and an antenna is combined with a first passive antenna circuit to provide an extended operating range. The first passive antenna circuit has a first coil and a first capacitor to tune the passive antenna circuit to a resonant frequency the same as the operating frequency of the RFID tag. The first coil has a central opening larger than the size of the antenna. The passive antenna circuit is arranged with the antenna located in the central opening of the coil, preferably in a co-planar manner, to promote inductive interaction therebetween. A second passive antenna circuit essentially identical to the first, but having larger dimensions, is positioned with the coil of the second passive antenna circuit surrounding the first coil to extend the operating range even further.

摘要： A data token with extended operational lifetime incorporates operational circuitry requiring D.C. power, a battery for supplying D.C. power to the circuitry, a power switch coupled between the battery and the circuitry, and a frequency selector for sensing remotely generated signals and for operating the switch when such signals are received so that D.C. power is applied to operate the circuitry only when the remotely generated signals are sensed in order to confine energy drain from the battery to only those periods when circuit operation is needed and extend the useful lifetime and range of the data token. The frequency selector is a crystal having a specific resonant frequency which only responds to remotely generated signals of the matching frequency. The switch is an FET switch. An integrator circuit is coupled between the frequency selector and the FET switch to smooth the D.C. voltage developed by the crystal.

摘要： An organizer management system for facilitating the location of an item stored in one of several drawers in one or more drawer organizer cabinets. Each drawer has an LED mounted on a front panel and a circuit having a crystal with a specific resonant frequency. The resonant frequency of the crystal in a given drawer is different from all other crystals in the system. All drawer circuits are coupled in parallel to a computer-controlled r.f. signal generator. To locate a particular item, the user enters a description of the item into a system computer, which contains a list of items in the system and the corresponding frequency for each item. The computer then operates the r.f. generator to generate an r.f. signal of the correct frequency for the specified item. The LED on only the drawer containing that item is activated, so that the user can visually locate the correct drawer.

摘要： A traffic signal head uses a plurality of LED light sources mounted in one or more containment volumes in a housing. One version uses identical three-color LED light sources distributed through the containment volume: each source having a red light generating element, a yellow light generating element, and a green light generating element. A second version uses identical two-color LED light sources distributed through the containment volume, each source having a red LED light generating element and a green LED light generating element. For the second version, activation circuitry enables individual activation of the red LED elements to produce red signals, individual activation of the green LED elements to produce green signals, and concurrent activation of both types of LED elements to produce yellow signals. Both versions can be electrically configured to display any of the three colors, as well as special symbols-such as directional arrows.

摘要： A thin film magnetic core array has a large number of individual thin film core memory elements arranged on a substrate with X, Y, Z and SENSE conductor leads reeving through the core elements between contact pads arranged about the periphery of the array. Each thin film magnetic memory element includes a bottom pole, a top pole forming a closed magnetic path with the top pole, the structure surrounding the leads passing through the core, and insulation material for electrically insulating the leads from each other and from the pole pieces. The SENSE lead from the array is coupled to a miniature thin film transformer which amplifies the signals read from the individual core elements. The transformer has a bottom pole, a top pole forming a closed magnetic path with the bottom pole, including a central leg extending between the top and bottom poles, and a pair of electrically conductive coils mutually spaced in the region between the top and bottom poles.
