Abstract: A fixation clamp device includes a bracket having two flaps extended from a base plate which has a channel, and a block slidably coupled along the channel of the base plate with a fastener. The block includes a mouth and a port communicating with a bore, a fitting is engaged onto one of the flaps and coupled to the port of the block. A forcing device may force the block against the fitting. A gasket may be engaged between the port of the block and the fitting, and may include one end engaged into the port of the block. One or more further fittings may be selectively engaged onto the bracket, and coupled to the port of the block.

Abstract: A universal compressor device includes a cylinder disposed in a shell, a shaft rotatably and slidably received in the cylinder, three or more pistons slidably received in the cylinder to alternatively actuate the shaft to move axially relative to the cylinder, and two valve plates disposed on ends of the cylinder to control fluid flowing passage. One cover and one cap are selectively secured to the ends of the shell, to enclose and retain the elements within the shell, and for attaching to one vehicle. One or more other covers and caps may further be selectively secured to the shell, for attaching the universal compressor device to the other vehicles.

Abstract: Device and method for a damping function to reduce undesirable mechanical transient responses to control signals. In one aspect of the present invention, the damping function may be used to reduce overshoot and oscillation when a digital micromirror is driven from a landing plate to the flat or neutral position. In another aspect of the present invention, the damping function may be used to reduce transient resonance of a digital micromirror when the micromirror is driven to a landing plate.

Abstract: A method of addressing an array of spatial light modulator elements. The method divides the array into blocks of elements, provides reset lines (MRST) to each of the block of elements, separate from the other blocks of elements, as well as address voltage supplies (VCCADDR) to each of the block of elements, separate from the other blocks of elements, addresses data to each of the blocks independent of the other blocks, resets each of the blocks, and steps address voltage to each of the block, where only blocks that are being reset receive the stepped address voltage. A spatial light modulator array (32) is also provided that has a layout to facilitate the method, including internal or external circuitry (34) to provide control of the stepped addressing voltages.

Abstract: A closed-loop control of the transformer voltage in a Royer inverter for cold cathode fluorescent lamps to provide a wide dimming range capability, such as by way of example, an approximately 100:1 dimming range. This dimming range is achieved by a combination of current control and pulse control to provide a much wider dimming range than can be achieved by using either form of control alone. Various additional features and capabilities of the invention are also described.

Abstract: Disclosed is a mechanism for automatically changing closestool seat sanitary cover mainly includes a roll-up mechanism and a specially designed closestool seat. The roll-up mechanism includes a supply reel on which continuous sleeve-like sanitary cover is wound, an upper and a lower reels for pulling used sanitary cover away from the closestool seat, and a motor for rotating the upper and the lower reels in opposite directions. The closestool seat is substantially a C-shaped member having two end portions separately pointing to the supply reel and to the upper and the lower reels.

Abstract: A method for controlling a digital micromirror device 40 resulting in decreased mechanical stress, longer device lifetimes, decreased incidence of spontaneous bit reset, and increased pulse-width modulation accuracy. To reduce the device stress, the bias voltage 142 applied to the mirror 50 may be reduced after the mirror 50 has been latched. To prevent premature mirror changes, the address electrode bias voltage 140 may be reduced after the mirror is driven to the desired position. To ensure that the mirror 50 returns to the neutral position during reset, the mirror bias voltage 142 may be raised from ground potential to approximately halfway between the two addressing voltages during the reset period 152. To reduce the effects of hinge memory and to ensure that the mirror 50 rotates toward the proper address electrode, the mirror bias voltage 142 may be gradually increased to allow the mirror 50 time to rotate towards the proper address electrode.

Abstract: A hopping and dancing shoe comprises a sole member, a base member parallel thereto, and a spring therebetween. Two means are provided by the spring to resist yawing of the sole member relative to the base member: (1) the spring has an axial extension of each end which is connected to the sole member and base member, respectively; and (2) the extreme outer coils of the spring are in contact with the sole member and base member, respectively, to provide frictional contact there between.
