Abstract: Systems and methods determine alignment between a wire and a laser beam in laser joining. A system for checking alignment of a wire relative to a beam of a laser includes a controller configured to align, by tooling, the beam with a sensor system. A laser generates the beam across the wire, with the beam directed to the sensor system. The sensor system measures light intensity of the beam. A processor computes a feature parameter representative of an alignment between the wire and the beam. The processor determines whether the feature parameter is within the process specifications.

Abstract: An improved system is provided for accurately referencing the revolving motion of electric motors used as positioning devices, and is particularly applicable to the automatic positioning and repositioning of ground station antennas in the reception of satellite TV signals.The system utilizes the action of the positioning motor itself as a reference and involves the extraction and counting of variations in the form of pulses produced in the current within the motor as a result of pulses generated, during motor operation, by the commutation process. A low impedance source senses the motor current pulses and feeds them to an active lowpass filter which suppresses any high frequency noise produced during motor commutation. Peak following circuitry, including separate positive and negative peak detectors, detects and follows the positive and negative peaks of the motor current pulses and produces a pulsating output waveform which is proportional to the number of motor current pulses detected by the peak detectors.

Abstract: An elongated active element for an antenna has an internal resonator providing a high quality matching impedance. The internal resonator is formed by a pair of conductors including an outer conductor and a coaxial inner conductor that is connected to signal ground. The signal connection of the active element is made to one end of the outer conductor in the neighborhood of the ground connection to the inner conductor. The inner conductor is shorted to the outer conductor at approximately a quarter of a wavelength, plus an integral number of half wavelengths, from the signal and ground connections to provide a parallel-resonant condition complementing the series resonant characteristics of the radiation impedance of the active element. Preferably, the active element is approximately a quarter wavelength long, and may be lengthened or shortened to obtain a desired radiation resistance. The antenna is easily fabricated from a length of coaxial cable.
