  • Patent number: 10376989
    Abstract: An assembly and method of reducing discoloration of a foam material resulting from laser processing the material comprising an assembly configured for positioning below the material being processed and for directing air into open cells of the open-cell foam material to pressurize the material during laser processing. The assembly comprises an air delivery mechanism comprising one or more apertures for an air chamber positioned directly below the material travel path. Aligning the one or more apertures with the axis of the laser beam and its focal point when the material is positioned above the one or more apertures and pressurizing or filling of the open cells with air in the direct vicinity of the target area reduces processing related discoloration of the material. The cells are laser processed concurrently with pressurization thereby substantially reducing settling of debris and smoke on the material and reducing discoloration.

  • Patent number: 6014596
    Abstract: An intelligent strobe system for vehicle applications includes strobe modules connected between the positive and negative DC power rails of the vehicle. One of the strobe modules includes a transmitter circuit for generating sinusoidal data and transmitting the data over the DC power rails. Other strobe modules include a receiver circuit to receive and decode the sinusoidal data to control the flash sequence.

  • Patent number: 4390172
    Abstract: A mechanism for quickly and precisely positioning one body relative to another body, which relies upon three support points between the two bodies. At a first point a hemispherical surface is received in an opening having the form of a trihedral pyramid. At a second support point a hemispherical surface is received in an opening having the form of a diahedral prism. At the third support point a rigid sphere held in loose confinement engages a flat surface.

  • Patent number: 4296542
    Abstract: In a manufacturing operation, a stretched diaphragm is used to support a quantity of small parts which are individually secured to the diaphragm in predetermined spaced relation. An individual part is elevated relative to the remainder of the array, for purpose of inspection or test, by displacing and even further stretching the associated portion of the diaphragm; then it is permitted to return to its original place in the array. When the parts are to be incorporated into manufactured assemblies each selected part is again elevated by displacing and stretching the associated portion of the diaphragm. The method is applied to the manufacture of microminiature electric circuits in which a flat wafer is first formed, and the wafer is then cut into a number of chips which must be individually tested and then they are incorporated into circuit assemblies.
