An adapter for permitting a medical diagnostic instrument having an illumination source including at least one LED (light emitting diode) to be used with a power supply normally configured for use with a diagnostic instrument having at least one incandescent lamp as an illumination source. The adapter includes circuitry for compensating LED specific characteristics for permitting the power supply to be used with the LED.

A memory device and method of performing a write operation in such a memory device are provided. The memory device comprises a memory array having a plurality of memory cells, and a plurality of word lines and a plurality of bit lines via which the plurality of memory cells are accessed. Write driver circuitry is responsive to a write request to write data into at least one memory cell during a programming interval by altering voltage on at least one of the bit lines connected to that at least one memory cell whilst one of the word lines connected to the at least one memory cell is selected, to cause a value indicative of the data to be stored in the at least one memory cell. At a start of the programming interval the at least one bit line is at a first voltage, and the write driver circuitry comprises first coupling circuitry responsive to the write request to couple the at least one bit line to a second voltage to cause the voltage on that at least one bit line to transition towards the second voltage. The first and second voltages represent the operating voltages of the memory cells. Further, additional coupling circuitry is provided which is triggered at a predetermined time during the programming interval to cause the at least one bit line to transition beyond the second voltage towards a third voltage. It has been found that such an approach significantly improves the writeability of memory cells within a memory device arranged to operate at low supply voltages.

A method of assembling an upholstered furniture piece comprising decorative fasteners comprising providing an underlayment material layer, a foam material layer and a covering material layer. The foam material layer is positioned between the underlayment material layer and the covering material layer. The covering material layer extends beyond the underlayment material layer and the foam material layer. Fasteners are used to fasten the underlayment material layer, the foam material layer and the covering material layer together forming a layered component. A template may be used to guide positioning of the fasteners. The fasteners are decorative fasteners. Excess covering material that extends beyond the fasteners is stretched around the edges of the layered component and is affixed to a bottom surface of the layered component, thereby forming a layered assembly. The layered assembly is affixed to an upholstered furniture piece.

The invention relates to a device for detecting and monitoring damage to races or adjacent regions of bearing rings (1, 2, 3) of anti-friction bearings. The device includes a measuring device, disposed in the anti-friction bearing chamber, having a sensor and structure for supplying sensor measurement data to the outside. The device has an energy source, which is also disposed in the anti-friction roller bearing chamber and which comprises a first coil (16) for the measuring device and a second coil (18) disposed outside the anti-friction bearing chamber and destined for inductive transfer of electrical energy to the first coil (16). The second coil (18) extends only over a part of the bearing circumference and the energy source comprises an energy accumulator (19) connected to the first coil (16).

A bone compression and distraction system which has an apparatus and a plurality of pins. The apparatus includes a body, a worm screw and a pair of pin attachment members. The worm screw is placed in the body and the pin attachment members are coupled to the worm screw, and constrained from rotation relative to the worm screw, wherein the worm screw has opposing threads extending away from a central region. Upon rotation of the worm screw, the pin attachment members travel in opposite directions, either toward each other or away from each other to either decrease or increase the spacing therebetween. A pin may be coupled to each of the pin attachment members.

The invention is applied to a compressor assembly wherein a coating is applied to the pocket in the piston for sliding engagement with a shoe for reciprocating the piston. The coating is a composite of solid particles of a lubricant, suspended in an adhesive, bonded to the to the aluminum alloy defining the pocket. More specifically, the coating comprises particles of polytetrafluoroethylene (PTFE) suspended in an epoxy resin having a low cross-linking characteristic. The particles of PTFE are sub-micron in size and the ratio of PTFE to epoxy resin is optimally one to one. The thickness of the coating is between two and ten microns and preferably substantially four microns.

Scanning mirror based display system and method. A method comprises sampling a scanned light provided by a scanning mirror, converting the sampled scanned light into an electrical signal, analyzing the electrical signal to determine a position of the scanned light, and controlling the light source or the scanning mirror based on the analyzed electrical signal. The electrical signal based on the sampled scanned light may be used to ensure proper operation of the scanning mirror display system, such as determining failure of the scanning mirror, proper rendering of colors, determining whether the scanned light is following a desired scan path at a desired scan rate, and so forth.

A cost-effective FPA includes a plurality of detectors per pixel, wherein radiation is directed by a microlens array into respective focal regions that are covered by the union of the detectors' collections regions within each pixel and any defective detectors are de-selected in the ROIC. The operability of each pixel is evaluated, and a map generated specifying detector de-selection for each pixel. This map is read into memory in the ROIC to de-select bad detectors. Bad detectors are preferably allowed to float to a photovoltage and re-emit some of their accumulated photo charge to neighboring detectors to improve collection efficiency. The radiation levels are preferably read out on a pixel-by-pixel basis. Accordingly, the signals from the selected detectors are combined within each pixel.

The performance of a solenoid drive liquid pump can be very dependent on the magnitude and stability of an input voltage, with non-ideal input power resulting in loss of efficiency and potential damage to the pump. Pulse width of drive signals provided to the pump, which cause solenoids to alternately energize to move liquid through the pump, may be adjusted in duration in order to compensate for non-ideal input voltage. A drive control module of the pump gathers voltage information, determines an improved pulse width based upon that voltage information, and then provides drive signals based upon the improved pulse width. Operating in this manner, a pump can operate at or near peak efficiency despite both significant variances in input voltage and non-sinusoidal input voltage, and without customized components or adapters.
