Abstract: An electronic cartridge that includes a pair of spring clips which attach a thermal element to an integrated circuit or an integrated circuit package. The integrated circuit/package is mounted to a substrate. The substrate may be a printed circuit board. The cartridge may have a plurality of pins that extend from the thermal element and through the substrate. Each spring clip may have a pair of bent portions that are attached to the pins of the thermal element. The spring clip exerts a pull force that pulls the thermal element into the integrated circuit/package. The bent ports can be deflected so that at least a minimum pull force is always exerted onto the thermal element even with dimensional variations in the parts of the cartridge. The bent portions can therefore accommodate for tolerances in the cartridge while clamping the thermal element to the integrated circuit/package.

Abstract: An emblem that is located within a recess of a cover. The cover may be part of a cartridge which also contains a number of integrated circuit packages that are mounted to a printed circuit board. The emblem is typically attached to the cover by an adhesive. The recess reduces the likelihood of the emblem being removed from the cover. The emblem preferably contains a hologram which can identify a type of cartridge produced by a manufacturer.

Abstract: Related components of a refrigeration system are cooled by refrigerant drawn from the system condenser by a pump which serves to raise the pressure of the condensate and move the condensate through the system related component. The condensate is reduced to a vapor as it absorbs parasitic heat losses in the components and is returned to the condenser where the parasitic heat losses are carried out of the system by the condenser coolant so that the system performance is not adversely effected.

Abstract: An electronic cartridge which may include an integrated circuit package that is mounted to a substrate. The substrate may include a plurality of conductive pads that are inserted into an electrical connector. The cartridge may be guided into the connector by a guide rail which has a latch slot. The electronic cartridge may include a latch which extends from a cover that is coupled to the substrate. The latch may extend into the latch slot to secure the cartridge to the connector.

Abstract: Apparatus for cooling the power electronics components of a variable frequency drive for the motor of a refrigerant system compressor. The components are mounted upon a heat sink and refrigerant from the system condenser is passed through the heat sink by means of a flow line and returned to the low pressure side of the system. A control valve is mounted in the flow line which throttles refrigerant passing through the line to produce cooling of the heat sink to maintain the temperature of the components within a desired range.

Abstract: Methods, devices and systems are provided which produce a synthesized stereoscopic image of a source image by forming at least two images from a source image where at least one image has been modified relative to the source image such that the images have a different spacial appearance than each other. A wide variety of modifications may be made to the source object in order to form modified stereo images. These modifications may involve modifying one or more images relative to the source image. For example, at least one image may be magnified, reduced, or rotated in the X, Y and/or Z plane relative to the source image. Alternatively or in addition, the position of one or more elements of one of the images may also be changed relative to the source image. Alternatively or in addition, at least one of the images may be transformed relative to the source image using a function which alters the position of elements of the image along the X or Y axis relative to the source image.

Abstract: An electronic cartridge which includes a cover. The cover is coupled to a substrate which has an integrated circuit package. A portion of the cover extends over and is spaced from a plurality of conductive pads located along an edge of the substrate. The conductive pads can be inserted into a card edge electrical connector that is mounted to a motherboard. The cover of the present invention protects the conductive pads while allowing the substrate to be plugged into a card edge connector.

Abstract: A retention system for an electronic cartridge which mates with connector that is mounted to a substrate. The system may include a first guide rail that is adapted to receive one edge of the electronic cartridge and a second guide rail that is adapted to receive another edge of the electronic cartridge. The guide rails may be mounted to the motherboard by a plurality of threaded fasteners and corresponding nuts. The guide rails guide the electronic cartridge into the connector. The system may further have a beam that extends from the first guide rail to the second guide rail. The guide rails and beam provide structural support for the electronic cartridge.

Abstract: An electronic cartridge. The cartridge may include a first cover and a second cover that are adjacent to a substrate. One or more integrated circuit packages may be mounted to the substrate. The cartridge may include a pin that extends from the first cover and which has a barb that is embedded into the second cover. The embedded barb will damage the second cover if the cover is removed from the cartridge. The present invention thus prevents the removal and re-installation of the cover from the cartridge.

Abstract: An electronic cartridge that may include a cover which is attached to a thermal element. A substrate may be located between the thermal element and the cover. The cartridge may include a first pin which extends from the thermal element through a datum hole of the substrate. The cartridge may also have a second pin which extends from the thermal element through a first float hole of the substrate. The first float hole may have a major diameter and a minor diameter. The major diameter of the first float hole may be larger than the diameter of the second pin so that the second pin can move relative to the substrate. The first float hole allows movement of the second pin when there is a differential thermal expansion between the thermal element and the substrate.

Abstract: An apparatus for automatically closing a shutdown seal on an open-drive centrifugal compressor to prevent the loss of refrigerant and damage to the seal, including a seal housing encompassing a rotor shaft, containing a shutdown seal and a running seal; the rotor shaft driven by a motor and axially moveable between the shutdown and running position, the shutdown position illustrated by the shutdown seal in the closed position and the running seal in the open position, the running position illustrated by the shutdown seal in the open position and the running seal in the closed position; a pressurized oil supply to move the shaft between the shutdown and running positions; a first sensor to determine when the motor is operating; a second sensor to measure the oil pressure; a solenoid controlling a release valve to remove pressure from the oil supply to move the shaft from the running position to the shutdown position once the motor has been inoperative for a given period of time and the oil pressure has fallen
