Abstract: A piezoelectric vibratory gyroscope utilizing an energy-trapping vibration mode comprises a piezo-electric plate having a principal surface and polarized in a thickness direction, and first through n-th electrodes (n being an integer not smaller than three) formed in a generally central area of the principal surface at positions corresponding to first through n-th vertexes of a polygon having n angles.  When the piezoelectric plate is excited in the energy-trapping vibration mode of a primary vibration, rotation of the piezoelectric plate around an axis perpendicular to the principal surface of said piezoelectric plate produces the Coriolis force to excite a secondary vibration which induces electric voltages at the first through the n-th electrodes.  A voltage difference is detected for at least two of the first through the n-th electrodes.

Abstract: A plate-imaging system and a plate-cylinder support structure are coupled in a manner that achieves precise spacing between a writing head and tree surface of a lithographic plate. The imaging unit is designed to permit the writing head undergo controlled advancement toward the plate cylinder, and includes a pair of rollers fixed with respect to the writing head and spaced so as to facilitate rolling contact with peripheral segments of the cylinder.      When the imaging unit is brought into contact with the structure containing the plate cylinder, the writing head is advanced toward the cylinder until the rollers make contact with the peripheral segments. The alignment between the rollers and the writing head is fixed such that rolling contact between the rollers and the peripheral cylinder segments ensures proper spacing between the writing head and a plate mounted to the plate cylinder. To ensure a constant tangential (linear) rotation velocity of the plate cylinder regardless of its diameter, the plate cylinder is driven with a fixed-diameter drive gear. In this way, the tangential velocity of the plate cylinder is constant and determined by the pitch diameter of the drive gear.

Abstract: This invention relates to an improved liquid soap dispenser of the type ones which are commonly located in public washrooms and the like. These kind of soap dispensers include a frame, a manually operable pump mounted on the frame and a reservoir operatively connected to the pump for supplying soap to be dispensed. The soap is generally dispensed when a tube, connected to the reservoir, is squeezed. The current invention provides simple and efficient ways for controlling the quantity of soap dispensed from such liquid soap dispenser. As such, the amount of pressure provided to the tube is varied, thereby varying the amount of soap dispensed. Preferably, the pump includes a handle and a wall portion facing each other on opposite sides of the tube. The wall member is pivotable about a pivot point, so that by increasing the angle between the wall member and the tube, the handle does not compress the tube as much and thus less soap is dispensed.

Abstract: A telecommunication switch for handling both synchronous transfer mode (STM) digital data signals and asynchronous transfer mode (ATM) digital data signals includes a flexible link list manager for mapping input slots to output slots, an input hybrid page, an output hybrid page and a hybrid routing table for managing the time slot interchange function. The STM data stream is segmented to form fixed length, serially propagating digital data words. The segment length of each STM data word is equal to the ATM cell length. The number of bytes in each STM segment and the number of bytes in each ATM cell are the same, and the STM segments and ATM cells are equal in duration. Because the ATM and STM signals are routed through a common switch, it is not necessary to split the two types of traffic before switching can be performed. Consequently, the switch can support any network distribution of ATM and STM traffic with the same switching equipment.

Abstract: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery systems are disclosed herein. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared to prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side effects. The battery case allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module (32), the batteries are bound within a bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power. The fluid-cooled battery pack (39) includes a battery-pack case (40) having coolant inlets (41) and outlets (42); battery modules within the case such that they are spaced from the case walls and from each other t o form coolant flow channels (43) along at least one surface of the bundled batteries; and at least one coolant transport means(44). The width of the coolant flow channels allows for maximum heat transfer. Finally, the batteries, modules and packs can also include means f or providing variable thermal insulation to at least that portion of the rechargeable battery system which is most directly exposed to ambient thermal conditions, so as to maintain the temperature of the system within the desired operating range thereof under variable ambient conditions.

Inventor: SMITH DEREK

Filed: 1999-12-17
Granted: 2008-04-01
Abstract: A contact lens and a method and apparatus for manufacturing a contact lens having areas of different thickness, the contact lens being compensated for differential shrinkage during the manufacturing process. The angular offset of the cylinder axis due to differential shrinkage is compensated for by introducing an equal and opposite offset during the manufacturing process. The axis offset caused by a particular manufacturing process is experimentally determined, i.e., for each intended cylinder axis, the corresponding offset (in terms of degrees of rotation) is determined. The lens compensation is implemented by adjusting the manufacturing process so that upon curing the lens corresponds to the desired, prescribed lens, without any axis offset.
