An arrangement is provided to correlate random connections made at one end of a multiwire cable with connections that are to made at the opposite end of the cable, in which the different leads of the cable are usually separated, for example, by a distinctive color pattern. The arrangement includes identifying the respective leads by a distinguishing marking, connecting a first end of the leads to a first connector, sensing the distinguishing marking of the lead connected to each contact of the first connector, and, responsive to the first end distinguishing marking, generating a first order identifying signal. The arrangement also includes identifying the respective leads by a distinguishing marking at a second end of the leads, sensing the distinguishing marking of each lead at the second end of the leads, responsive to the second end distinguishing marking, generating a second order identifying signal, responsive to the first and the second order identifying signals, generating a crossover matrix, which correlates the first and the second ends of the leads, responsive to the crossover matrix, generating a crossover network, and inserting the crossover network in a second connector for establishing connectivity between the first and the second connectors. The arrangement may also include generating the crossover network by selecting a crossover network from a plurality of prefabricated crossover networks or, alternatively, fabricating a crossover network.
A cable having at least two twisted wire pairs, each of the wires in the twisted wire pairs having wire jacket with a respectively different color, is automatically assembled by automatically detecting the colors of the wire jackets and automatically positioning the wires of the twisted wire pairs in a predetermined sequence based on the colors of the wire jackets. A machine vision system is used for detecting the colors of the wire jackets. A connector is then automatically attached to the automatically positioned wires. The connector may be a 110 connector, a D8GS connector, an RJ45 connector or an RJ11 connector.
A pulsed radar detector to be used for airbag triggering prior to a collision between a vehicle on a roadway and an impacting target object, has sets of transmitters and receiver separately disposed on a the side of a vehicle so as to create a bistatic antenna pattern. The transmitting antennae are mounted relative to receiving antennae so as to control the amount of direct radiation from each transmitter antenna and said receiver antenna so as to create a modulation of a received target signal. A signal processor determines the period of the modulation in order to obtain a measure of target velocity. The amplitude of the modulation is determined so as to have a measure of relative target size. Using this data, a computer continuous calculates the predicted time and point of impact in order to initiate release of an airbag at a predetermined time before impact between said object and the side of said vehicle.
Patterns for a routable interface of the signal lines of a integrated circuit device include several groups of terminals distributed about the pattern center, each group clustered along a corresponding curvilinear reference segment extending outward from the pattern center to its perimeter. Routability zones are created between each successive pair of groups. For higher terminal density, in at least one of the terminal groups of the pattern, either the offset of the terminals from the reference line segment is not uniform, or the distance of the terminals from the pattern center does not increase uniformly. A portion, preferably at least about 50% of the terminals in a group of the pattern are not collinear with, but offset from, the reference segment. A portion, preferably at least about 90% of the terminals in a given terminal group are each closer to the reference line segment of that terminal group than they are to the reference segment of another terminal group. The patterns of this invention can be employed on IC chips, IC package layers and PCB layers for patterning of terminals, pins, via, pads and another connector devices useful in IC devices.

A multilayered circuit component includes one or more substrates. A first surface of one of the substrates includes circuit paths and other current carrying elements. A second surface of the same or another substrate also includes circuit paths and other current carrying elements. An aperture extends through at least a portion of the one or more substrates. The aperture is defined by a first opening on the first surface, a second opening on the second surface, and an internal surface of the one or more substrates that extends between the first surface and the second surface. A first trace element is provided over a portion of the internal surface of the aperture to extend between the first surface and the second surface. The first trace element extends onto the first surface to form a first partial perimeter of the first opening. A second trace element is provided over a portion of the internal surface of the aperture to extend between the first surface and the second surface. The second trace element extends onto the first surface to form a second partial perimeter of the first opening.
