  • Patent number: 6031773
    Abstract: A method of stress testing a DRAM such that higher voltages of up to the supply voltage VDD may be applied to the oxide of memory cell capacitors. The DRAM is driven into a stress test mode when the sense amplifiers have been isolated, the precharge voltage and the half bitlines have been grounded, and the word line boost circuitry has been disabled or set to operate at a lower voltage level. These conditions allow the memory cell capacitors, isolated from the sense amplifiers and the word line boost circuitry, to be stress tested independently at a lower power supply and word line voltage levels than are used to stress test conventional DRAMs. The memory cell oxide stresses are applied at room temperature, in wafer form, in seconds instead of hours, and before the configuration of redundancy elements. The inventive method permits the critical burn-in VDD value to be chosen so as to optimize burn-in of the memory cell capacitors and peripheral CMOS circuitry.

  • Patent number: 6002447
    Abstract: Video signal processing apparatus includes a picture enhancement processor for processing a video signal to produce an enhanced video signal. The video signal includes a signal component representing video image data and another signal component representing non-image data such as vertical sync and a binary information component. The binary information component represents binary information that may occur, for example, during vertical blanking such as closed caption data, content advisory information (V-chip), or extended data services information. A control unit modifies the enhancement performed by the picture enhancement processor during intervals of the video signal that include non-image information. Modifying enhancement processing (e.g., reducing or disabling) during intervals that include the non-image information reduces degradation of the non-image information caused by the enhancement processing.

  • Patent number: 5907369
    Abstract: A television system utilizes a common signal processing unit (e.g., a common chrominance demodulator) for processing a combined video signal suitable for coupling to a display device for producing an image having a portion attributable to a main video signal and a portion attributable to an auxiliary video signal. If the common signal processing unit relies upon the color information (e.g., color burst) contained in the main video signal, and the main signal is either non-existent or lacking such color information, then a substitute color information signal will be generated so that the combined video signal may be processed to roduce a color auxiliary image, and a monochrome (or non-existent) main image.

  • Patent number: 5801198
    Abstract: Treating mammals having ischemic bowel with a therapeutic quantity of pyruvate enterally or parenterally will retard neutrophil infiltration and retain morphology during and following the bowel ischemia. The pyruvate is introduced into the patient enterally or parenterally during the bowel ischemia or the succeeding bowel reperfusion and, preferably, prior to the bowel ischemia. The pyruvate dosage is from 1% to 20% by weight of the patient's caloric intake.

  • Patent number: 5773098
    Abstract: A thin fluoropolymer film is covalently bonded to a microporous ptfe film to make a bilayer for separation, filtration or reverse osmosis, by exposing the microporous film to perfluorocyclohexane under plasma. The perfluorocyclohexane molecules undergo scission and the fragments combine on the substrate to make a fluoropolymer film wherein the pores of the substrate have not been completely closed by the coating.

  • Patent number: 5704983
    Abstract: A barrier coating is formed on a polymeric article, such as on the interior of a thermoplastic container. An oxidizing gas is converted to a plasma in a plasma chamber remote from the treatment chamber. The resulting plasma-activated oxidizing species are delivered to the interior of the container. An organosilicon reactant vapor is separately but simultaneously delivered to the interior of the container so that the organosilicon vapor and oxidizing active species mix within the container. An electric qfield is also applied to the container, so that the reaction products are deposited under the influence of the electrical field to form the barrier coating.

  • Patent number: 5677047
    Abstract: A substantially cylindrical bar of microporous PTFE is non-fibrillated and incorporates pores within any cylindrical surface within the bar centred about the central longitudinal axis of the bar that are of substantially uniform size and are substantially uniformly distributed within that surface. The process for producing such a bar includes the step of applying a substantially radial compressive force to pre-heated and cooled granules of PTFE and subsequently re-heating and cooling the compressed granules, while a film of non-fibrillated, microporous PTFE is formed from the cooled bar, the plane of the film being perpendicular to the direction of the radial compressive force whereby the pores within any plane substantially perpendicular to the thickness of the film are of substantially uniform size and are substantially uniformly distributed within that plane and all such parallel planes.
