Abstract: An apparatus with a specific connector configuration is disclosed. A system that includes the connector configuration of the apparatus is also disclosed. The apparatus includes a first connector having a first guide pin insertable into a first guide socket of a first mating connector. The first guide pin is blocked from being inserted into a second guide socket of a second mating connector. The second guide socket has a different shape than the first guide socket. The apparatus includes a second connector having a second guide pin with a different shape than the first guide pin. The second guide pin is insertable into the first guide socket of the first mating connector and insertable into the second guide socket of the second mating connector.

Abstract: An apparatus includes a rigid structure having first and second collars, a quick connect connector having first and second shoulders, and a spring biasing the connector toward an extended position with the first shoulder against the first collar and the second shoulder against the second collar. The first collar and the first shoulder form an inwardly and rearwardly angled contact surface there between, and the second collar and the second shoulder form an inwardly and rearwardly angled contact surface there between. The connector is centered in the first and second collars unless acted upon by a force overcoming the spring and pushing the connector to a retracted position with the first and second shoulders out of contact with the first and second collars. When retracted, the connector may adjust its position longitudinally, vertically, laterally or angularly to facilitate coupling with a mating fixed quick connect connector.

Abstract: A method includes securing a midplane in a chassis, wherein the midplane has one or more connectors, and securing a circuit board in a module, wherein the circuit board has one or more connectors secured along a leading edge of the circuit board for selectively connecting with the one or more connector on the midplane. The method further includes positioning the module so that the circuit board within the module is orthogonal to the midplane, and manually actuating a handle from an unlatched position to a latched position to rotate a cam plate and cause a cam surface of the cam plate to pull the circuit board toward the midplane and connect the one or more connector on the circuit board with the one or more connector on the midplane.

Abstract: An apparatus includes a chassis securing a midplane and forming a bay orthogonally aligned with the midplane. A module secures a circuit board with connectors for connection with connectors on the midplane. A handle includes a proximal link pivotally coupled to the module, a distal link pivotally coupled to the proximal link, and a spring for transmitting torque from the distal link to the proximal link. A cam plate is secured for rotation with the proximal link, wherein the cam plate includes a cam surface for engaging a latch arm that extends into the bay. Still further, an over-center spring is used to retain the cam plate in a latched position. Manual actuation of the handle from the unlatched position to the latched position causes the cam surface to pull the circuit board toward the midplane and connect the circuit board connectors with the midplane connectors.

Abstract: An acoustic cooling apparatus for a computing system, includes a cooling muffler comprising sidewalls and an endwall, the sidewalls being substantially parallel to each other, each sidewall being substantially perpendicular to the endwall at one end, the walls forming an enclosure having an open end opposing the endwall. Each sidewall includes an exhaust opening. At least a portion of the interior of each wall of the enclosure being covered by sound absorbing material for attenuating air cooling sound.

Abstract: A data storage library includes a drive enclosure bay which can be adapted to work with multiple air-flow configuration requirements. This is accomplished by creating air-flow ports in the top and bottom of the drive enclosure bay, by forming drive tray slots and printed circuit board ports in associated drive trays, by creating frame ports and PCB notches in associated interface cards, and replacing traditional connectors with slimmer but longer connectors that provide additional standoff and improved air-flow.

Abstract: A dialysis method based upon urea kinetic analysis is provided. An objective of the method is to provide guaranteed dose hemodialysis by optimization of each dialysis treatment. The method does not rely upon dialysis treatments equal in time. The method includes determining a preferred post-dialysis urea concentration for a patient and predicting a time endpoint for the dialysis. Computer automation makes the method advantageous in a large, busy dialysis center.
