Granted: 2000-07-25
Abstract: An integrated circuit output driver which reduces the effect of power supply and/or integrated circuit fabrication process variations on signal propagation delay.      The output driver produces an output signal V out as an increased drive strength replica of an input signal V in. A pre-driver receives V in and produces an intermediate, inverted replica V int thereof. A driver is electrically connected to the pre-driver's output to receive V int. V out appears at the driver's output as an inverted, strengthened replica of V int. A first feedback circuit electrically connected between the driver's input and output applies a pull-down signal to the driver's input in response to a falling edge of V in, with the pull-down signal's strength varying in inverse proportion to propagation delay of the falling edge of V in. A second feedback circuit electrically connected between the driver's input and output applies a pull-up signal to the driver's input in response to a rising edge of V in, with the pull-up signal's varying in inverse proportion to propagation delay of the rising edge of V in.

Granted: 2007-05-08
Abstract: An automated means for hydrating and packaging a molded hydrophilic contact lens in one of the mold parts used to mold the lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. The hydration carrier is then transported through a plurality of flushing or extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis. A final robotic dis-assembly device separates the top chamber plate and lens molds in the mold carrier plate, to provide fully hydrated lenses in a concave lens mold ready for transfer to inspection and packaging stations. Following inspection of the lens, the concave lens mold is dosed with saline and used to form part of the package used to distribute the lens.

Abstract: The invention relates to the construction of optical multipath switches based on electrically switchable photonic crystals. A filled photonic crystal, switchable electrically and/or by light, is used as a tunable mirror.  By creating selective optical deformations in the photonic crystal, its properties can be influenced in selected areas in terms of transmission capability. This is done preferably by application of a strong electrical field.      Light is coupled in and out via fixed photonic mirrors located at an angle to the photonic crystal. The optical switches of the invention find application in switching networks and serve the purpose of service selection. A very high packing density may be achieved.

Abstract: An integral water circulation apparatus supplies instant hot water at hot water faucets remotely located from the building water heater through a convective circulation flow of hot water from the water heater. It is therefore simpler in design, less expensive to install, and more reliable than the more complex prior art systems. It has the further advantages of not mixing heated water with cold water being supplied to cold water faucets throughout the building and of preventing cold water from flowing up the return line to the hot water faucet.

Abstract: This disclosure describes fabric and a method for making fabric, for use in a flexible pressure vessel or other fabric structures, which has an unbalanced woven construction and has a balanced or nearly balanced modulus of elasticity for the end-use conditions of this fabric.  Unbalanced woven fabrics that do not have balanced properties produce unequal stretching and are susceptible to premature failure. The present invention of unbalanced woven fabric construction with balanced mechanical properties such as modulus of elasticity can be used to optimize fabric strength, mass, volume, and performance characteristics and also reduce manufacturing costs for various fabric structure applications. Balanced mechanical properties for the fabric structure are achieved by altering the force of the fabric by increasing or decreasing the number of yarns in a particular direction of the fabric, by changing the strain during stretch of the fabric, or by alternative weaves of the fabric.
