Abstract: A lid actuated device foot lifts a device to facilitate cooling. The device foot includes a device lid, and at least one lifting cam coupled to the device lid through a hinge. The lifting cam rotates about the hinge on an axis and has an eccentric contact surface capable of contacting a supporting surface. The device is thus lifted when the device lid is moved to a first position corresponding to an operational state thereby rotating the lifting cam about the axis. The contact surface is non-lifting when the device lid is in a second position corresponding to a non-operational state of the device.
Abstract: A serial data to parallel data converter is disclosed which has the advantage of accurately converting high frequency serial data to parallel data while using clock signals operating at a relatively low frequency. A low bit error rate is achieved by avoiding the use of multiple high speed clock lines typically found in other converters. The simplified circuit design also has the advantage of requiring minimal semiconductor layout area and reduced power requirements. One embodiment includes a buffer, a first data delay line, coupled to receive serial data from the buffer, and a phase lock loop (PLL), coupled to receive serial data from the buffer. A second data delay line is configured as a voltage controlled oscillator (VCO) within the PLL. The PLL locks onto the incoming serial data signal and provides a control signal back to the first data delay line to ensure it is storing serial data bits as they arrive.

Abstract: Various types of articles having various deposition coatings applied using a gas vapor deposition process are provided. A system evacuates gases from the article or a deposition chamber prior to depositing a coating. The coating may be applied throughout the inside of an article or may be selectively applied to a portion of the article. The article may be moved relative to the gas jet or the gas may be moved jet relative to the article. Stencils may be used to pattern the coating on the surface of the article. The articles are coated in a pressure of approximately 5 millitorr. Articles may be cylindrically shaped, leadframes on a reel, substrates, or printed circuit boards.
Abstract: Fluorine and/or silicone containing block copolymers are described which are the copolymerization product of mono; di- or trivinyl substituted poly(ethylene oxide) prepolymers (A) and fluoroalkyl-alkylene acrylates or methacrylates (B1), oligosiloxy-silyl alkyl-acrylates or methacrylates (B2), ether copolymerizable comonomers (C), and 0.1 to 10% of a di- or polyvinyl crosslinking comonomer (D) of 200 to 1000 molecular weight. The novel block copolymers are prepared in solution or bulk and form hydrogels, which are characterized by high oxygen permeability, resiliency, flexibility and wettability and are therefore well suited as biocompatible polymers, especially as contact lenses.
Abstract: An iontophoretic agent delivery device, having a layered structure and peripheral insulation, wherein ion transport occurs through two opposing surfaces of said device. The device is especially suited to agent delivery through body surfaces exposed to body fluids. A method of delivering an agent through a body surface exposed to body fluids is also disclosed.
