  • Thermally enhanced metal capped BGA package
    Publication number: 20050179125
    Abstract: A thermally enhanced wirebond BGA package having a laminate substrate, an IC device mounted on the substrate, and a metal cap defining a cavity inside the package between the IC device and the metal cap. A substantial portion of the cavity is filled with a thermally enhanced epoxy encapsulant establishing a thermal conduction path between the IC device and the metal cap. The BGA package may be further enhanced by bonding a metal heat slug on the laminate substrate and mounting the IC device on the slug.

  • Multichannel position sensing detector
    Patent number: 5723869
    Abstract: A position sensing detector in which each of a plurality of sensing channels is provided with ends and an output current lead at each end of each channel. A light spot is imaged along the length of the channel. The channels are electrically isolated from each other. The channels may be proportional to a selected keystone pattern, and the channels may be rectangular-shaped and accommodate keystoning effects of an imaged beam.

  • Process for the preparation of stable white grape juice
    Patent number: 5585128
    Abstract: A process for the preparation of a non-citric fruit juice, particularly white grape juice, in the absence of sulfites, including the steps of cold pressing, filtering the juice obtained from pressing, holding the juice in the absence of sulfites, heat treating the juice for a time and at a temperature sufficient to eliminate microbiological and enzymatic activity; and cooling the heat treated juice is described. The process can also include sparging with sufficient nitrogen to achieve < 5 ppm dissolved oxygen.

  • Segmented position sensing detector for reducing non-uniformly distributed stray light from a spot image
    Patent number: 5554858
    Abstract: A position sensing detector in which each of a plurality of sensing channels is provided with ends and an output current lead at each end of each channel. A light spot is imaged along the length of the channel. The channels are electrically isolated from each other. The channels may be proportional to a selected keystone pattern, and the channels may be rectangular-shaped and accommodate keystoning effects of an imaged beam.
