  • Patent number: 6388813
    Abstract: A stack of laminated transparent lenses consists of two alternating optically clear materials in intimate contact. The materials are a plastic lens and clear adhesive. The adhesive is uninterrupted. The lens and the adhesive have refraction mismatch of less than 0.2. A tab portion is part of each lens and acts as an aid in peeling away the outermost lens after contamination of the lens layer during racing conditions. The lens stack can be mounted to the posts on the face shield of a racing helmet or laminated directly to a windshield.

  • Patent number: 6217579
    Abstract: A cylinder-shaped expandable spinal implant is disclosed. The implant is a hollow housing having a cylinder-shaped wall, with a circular sealed distal end, and an opposite proximal circular open end. The open end of the housing has internal threads for securing a cap to it. A removable cap is threaded on the open end of the housing. The housing has two opposite large rectangular openings located longitudinally in the wall of the housing for receiving two arcuate sections. Each arcuate section is positioned in the rectangular opening in the wall of the implant. A locking means for locking the arcuate section in the rectangular opening in the wall is provided. A plurality of small ports are drilled in the wall for allowing bone growth after implantation of said implant in a patient. The arcuate sections have transverse ribs for locking the implant in position are implantation. Openings between the ribs are provided for allowing bone growth.

  • Patent number: 5945591
    Abstract: A solid state electronic digital pressure gage which is responsive to the inlet pressure (P1) and the outlet pressure (P2) of a device undergoing a flow test to measure the pressure differential across the device at different flow rates. The pressure gage includes a housing, a face plate mounted on the housing, and a printed circuit board may be mounted on the back of the face plate on which various electronic circuitry, components and controls are mounted. Certain of the controls may be adjustable from the front of the face plate. A pair of solid state pressure transducers is mounted on the housing, and these transducers generate electric signals which are a function of the pressures applied to the transducers. The transducers are connected to an electronic signal difference determining circuit which is included in the electronic circuitry, and the difference determining circuit generates a signal representing the difference between the pressures applied to the two transducers.
