Abstract: A system for determining a location of a selected vehicle from which an alarm signal is generated which includes a fixed array of cellular sites each site having a wireless signal detecting and generating units each of which is capable of receiving an input alarm signal having a signal strength which is a function of the distance between the position of the vehicle generating the alarm signal and the position of each of the wireless signal detecting units. Each unit also is capable of transmitting an output signal which is a function of the strength of the input alarm signal.
Abstract: A novel cursor construction for a digitizer tablet, wherein the cursor coil is wound on a one-sided bobbin which is then seated in a blind hole of a transparent base, with a crosshair molded into the base and aligned with the coil.
Abstract: Disclosed herein are position determining apparatus and conductor structures or grids therefor. The conductor structure for each axis includes a number of conductors, at least one of which is run in a serpentine path with a non-uniform repeat increment. The repeat increment, which is the spacing between one run and the next of the same serpentine conductor, is constrained by a maximum repeat increment, or a minimum repeat increment, or a maximum change in repeat increments between consecutive runs of a same conductor, or combinations thereof. In the preferred embodiments, there is at least a constraint on the maximum repeat increment to provide noise immunity. The conductors are arranged for each axis of the grid in a pattern such that signals obtained for that axis may be processed to provide binary members in a Gray-type code each unique to a small region of the active area in which the coil center is located.
Abstract: A circuit device, made up of a reduced number of components, for simultaneously turning on a plurality of power transistors, being of a type adapted to be connected between the output of an oscillator and the bootstrap input of a turn-on circuit which are both incorporated into an integrated circuit also incorporating said transistors, further comprises:a first capacitor having one end connected to the oscillator output and the other end connected to the bootstrap input via a diode,a second capacitor connected between the bootstraps input and one voltage supply pole, anda second diode connected between the junction of the first capacitor and the diode, and the voltage supply pole.
Abstract: In a bearing arrangement for a rotary drum, the ends of two cradles are attached to load-carrying rollers which rotate freely over a surface area of a race of the rotary drum. The cradles run in self-aligning bearings in a load-bearing structure via intermediate cradles. Each load-carrying roller runs in bearings at the end of its respective cradle, in a manner which avoids slanting and which is free of axial clearance. Each cradle runs in rocker bearing located between its two load-carrying rollers, without bearing clearance at the end of an intermediate cradle. One of the intermediate cradles runs in a journal bearing with an axial clearance equal to or larger than the axial dislocation of the load-carrying rollers in the load bearing structure when the rotary drum is in operation.
Abstract: A method of lowering the power absorbed by an interface circuit, in the "power-down" state thereof, as incorporated to a telephone exchange and connected to a telephone subscriber line, being of a type which comprises a monitoring circuit portion connected between the line and the exchange. The method involves the steps of,detecting the polarization level of a conductor in the line,comparing that level with a reference value by means of a comparator having an input connected to the line and an output connected to the input of the monitoring circuit portion,switching the interface circuit to a standby state on a higher level than the reference value being sensed,once again detecting the polarization level of the line, this time through the interface circuit, andactivating the telephone exchange when, on completion of the second detection step, the polarization level stays above the reference value.

Abstract: A dielectric layer of first interconnection for electronic semiconductor devices, specifically CMOS circuits, comprises a first thickness of tetraethylorthosilicate which is overlaid by a layer of self-planarizing siloxane. That layer provides a surface structure which is permissive of the subsequent conventional masking and electric contact attaching steps.
Abstract: A text mode color selection system for a monitor which permits the selection of the color tone of the text mode voluntarily in accordance with the preference of a user also the color tone can be changed to another one when a user feels dissatisfied at a color of text mode comprised of a video memory, buffer, video output section, reset section, counter, NOR gate, inverters, NAND gates, diodes, resistors, and light emitting diodes, so that the color of the text mode is changed into three different colors such as amber, green, and white on blue in accordance with the number of operations of a text mode selection switch.
Abstract: A cut, strip and wrap tool for removing insulation from a wire while wrapping about a terminal, comprising on a rotatable bit a wire-receiving slot which is circumferentially offset from a sleeve window at one end to a cutter at the opposite end. The bit configuration is such that both left hand and right hand loading of the wire by the operator is allowed.
Abstract: Mass-flow meter with temperature sensors, designed for measuring mass flow rates of liquids or gases, containing a heat conductive tube, through which the mass flow to be measured occurs and of which the beginning and the end are kept at the same temperature, as well as one or more means to raise the temperature in the tube and means to measure the temperature of the mass in the tube in different places. In or on the tube one or more facilities are applied with which the zero-offset of the means to measure the temperature can be eliminated in a physical instead of an electronic way.
Abstract: The present invention comprises the use of a copper/nickel containing alloy composition or application of a protective nickel alloy coating to copper current-carrying leads to prevent electrolytic migration between tape automated bonding (TAB) package leads.

Abstract: A defect print detecting device having photographing means for photographing as an image the surface of a printing plate having a pattern to print and mounted on a plate cylinder, which compares reference image data acquired at the beginning of printing using the photographing means with checking image data acquired during printing, thereby determining the quality of the printed matter.
Abstract: The invention concerns a temperature conditioning support for thermal tests on small objects such as semiconductor wafers incorporating integrated circuits. It consists of a platen and a hollow base. Inside the hollow cavity is contained a serpentine which can convey thermal fluid capable of heating and/or cooling the platen to achieve temperature regulation of the object placed on the platen, according to data supplied by a thermometric system that includes a temperature sensor associated to said support. The platen is made of electrically insulating and thermally conducting ceramic, the base being made of a material whose thermal expansion coefficient is substantially equal to that of the platen. A thin-film electrical resistance can be provided to ensure heating and, optionally, temperature measurement of the platen.
