  • Patent number: 6641939
    Abstract: The invention relates to the utilization of doped alumina for static charge sensitive applications, and to methods for making and using the same, e.g., for varying the electrical conductivity of alumina by doping with an appropriate transition metal oxide and subsequently heating to high temperatures in a reducing environment. This treatment allows the electrical conductivity to be tailored and thus provides a cost effective means for producing components with controlled resistivity.

  • Patent number: 6632127
    Abstract: The present invention is a polishing pad conditioning head for a CMP and similar types of apparatus that is especially useful in conditioning the surface of fixed-abrasive CMP polishing pads to maintain optimal process conditions for the planarization process on dielectric and metal films on semiconductor wafers, as well as wafers and disks used in computer hard disk drives. The polishing pad conditioning head comprises a substrate and a layer of fine-grain chemical vapor deposited polycrystalline diamond that is bonded onto the substrate. Alternatively, a thin sheet of polycrystalline diamond may be deposited on a preferred growth substrate by a chemical vapor deposition process, then removed from the growth substrate and then bonded to the CMP conditioning disk substrate.

  • Patent number: 6582080
    Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for importing image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD). Reflective surfaces within the projector may be covered or coated with material that alters the polarization of reflected stray light from the defined orientation or depolarizes the reflected stray light.

  • Patent number: 6573830
    Abstract: The progressive vehicle brake light system of the invention consists of a brake sensor arranged to sense the travel of a brake pedal and a brake light display arranged to illuminate or extinguish in sequence or progressively in response to the travel of the brake pedal. A microcontroller is provided for receiving a signal from the brake sensor and controlling the brake light display accordingly. The brake sensor is typically an optical sensor utilizing infrared transmitters and receivers arranged to sense the distance and direction of travel of the brake pedal. The brake light display consists of a row of light emitting diodes (LEDs) which are arranged to illuminate from the opposite ends towards the middle as the brake pedal is depressed and to extinguish in reverse sequence when the brake pedal is released.
