  • Device and method for creating an areal light source
    Patent number: 5136479
    Abstract: A device and method to convert light from a point source into an areal source of displayed light. The reflective faces of dielectric mirrors enclose a point source of light. The mirrors repeatedly reflect the light from the point source inside the enclosure without significant absorption, thereby achieving a random distribution of position coordinates for the light rays departing the areal transmissive surface on the outside of the enclosure. The device and method may be used for backlighting a display or for other areal lighting systems.

  • Piezoelectric cell growth biosensing method using polymer-metabolic product complex interactions
    Patent number: 5135852
    Abstract: The invention relates to a piezoelectric biosensor device and also to a method and a system utilizing a piezoelectric biosensor device for detecting metabolic growth requirements, antibiotic responses, and the specific bacterial products of microorganisms. When a microorganism is grown in an appropriate nutrient medium containing a metabolic product responsive polymer, metabolic products of the organism acidify the medium and precipitate a polymer metabolic product complex which deposits or accumulates on the surface of a piezoelectric biosensor device. The mass change on the surface of the device resulting from this deposit produces a change in the resonant frequency of the piezoelectric biosensor device which can be used to determine the growth and type of microorganism.

  • Fiber reinforced porous sheets
    Patent number: 5134016
    Abstract: A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient preheating of the sheet prior to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, taking them together at crossover points. The resultant web can then be directly heated very efficiently for molding. This web is highly porous allowing rapid heating at moderate pressure differentials during subsequent preheat steps. The microstructure created when the resin matrix forming fibers are initially melted further enhances heating capability because the structure retains porosity during the subsequent heating step required for molding.
