Abstract: A mouse finger rest is provided. The device includes a finger support having a lower leg and an upper platform, wherein the upper platform is rigidly affixed to the lower leg at an angle to rest substantially parallel to an upper portion of a mouse. The lower leg is disposed along a bracket, wherein a first end of the bracket and a second end of the bracket are removably securable to a front portion of a base of the mouse. In some embodiments, a protrusion extends perpendicularly from the lower end of the lower leg, wherein the protrusion is slidably disposed within a track disposed in a front portion of the base of the mouse.

Abstract: A gas chromatograph for connection to a source of carrier gas and a source of a sample gas. The gas chromatograph includes a first bridge circuit with a sample sensor connected therein and a second bridge circuit with a reference sensor connected therein. The outputs of the bridge circuits are digitized and then subtracted from each other in a processor.

Abstract: The present invention is directed to a gas chromatograph (GC) module having a column assembly and a printed circuit board mounted to a valve assembly. A plurality of electronic devices are mounted to the circuit board. The electronic devices include non-volatile memory, pressure sensors and detector devices.

Abstract: The present invention is directed to a gas chromatograph having a display screen. The gas chromatograph includes an explosion-proof housing and a transparent panel secured to the housing. The display screen is disposed in the housing and is visible through the transparent panel. A gas chromatograph (GC) assembly is disposed in the housing and includes a column for separating components of the gas and a detector for detecting the components of the gas. An electronics assembly is disposed in the housing and includes a microprocessor and memory. A graphical user interface (GUI) software application is stored in the memory and is executable by the microprocessor to display a plurality of windows on the display screen. The windows contain information about the operation of the gas chromatograph.

Abstract: A luminaire for high intensity indirect lighting providing a horizontally symmetrical light distribution with peak candle power at low angles is disclosed. The luminaire includes an inner light directing member nested in spaced relation within a generally dome-shaped outer translucent member. The inner light directing member includes means for directing the majority of light emitted by an axially located vertical light source out of the upwardly facing open end of the light directing member after no more than one reflection, and means for illuminating the outer translucent member to a substantially homogenious brightness level comparable to that of the surrounding ceiling.
