Abstract: A system for an electronic device includes a housing having one or more walls that define an internal region. An outlet port is fluidically coupled to the internal region of the housing, which allows emission of a fluid from the internal region of the housing as a first flow at a first temperature. A merging element, fluidically coupled to the outlet port, merges the first flow with a second flow, which has a second temperature that is less than the first temperature.

Abstract: A septic system thermal recovery mechanism includes a septic tank. The tank has a top, a bottom, and at least one upstanding side wall joining the top to the bottom. The top, bottom, and at least one sidewall define an interior of the tank, and the at least one sidewall is devoid of angular corners. A septic inlet is adapted and constructed to conduct septic waste material into the interior of the tank, and a septic outlet is adapted and constructed to conduct septic waste material out of the interior of the tank. A thermal exchange fluid conduit is embedded in the at least one wall of the tank The thermal exchange fluid conduit is connected to a source of thermal exchange fluid.

Abstract: An electronic control system, particularly adaptable to coin-operated laundry appliances, which enables owners of such machines to customize machine operation. Laundry parameters are stored in random access memory, and timing functions are performed in control logic. Thus, the owner may simply update the information on a computer and download the parameters to individual laundry machines. A portable receiver/transmitter may be utilized to transfer information to the laundry machine controller by way of an infrared communications link. Also disclosed is a reconfigurable fuzzy logic control which is general purpose, having a functionality that may be easily altered in accordance with the type of machine. The structure of the fuzzy logic controller is identical for all applications.

Abstract: A system for functionally testing opto-electronic devices, such as fiber-optic infrared receiver photodiodes, in the integral wafer or other optical port-exposed status. The testing arrangement uses a portable optical probe for communicating optical signals between the testing apparatus and the tested device in coincidence with electrical energization and functional operation of the electro-optical device by the test apparatus. The optical probe signals may be correlated in time relationship or other manner with the electrical signals applied-to the device-under-test. The invention provides simple conversion between a conventional electrical semiconductor device probe station and an electro-optical device probe station.

Abstract: A photo FET device having a large area backside optical energy reception surface is disclosed. The photo FET device is fabricated in the source gate and drain upward configuration using a lattice determining surrogate substrate and a mesa-forming deep etch processing sequence and then inverted onto a new permanent substrate member and the surrogate substrate member removed in order to expose the active area backside optical energy reception surface. Fabrication of the device from two possible indium-inclusive semiconductor materials and a particular gate metal alloy is also disclosed.

Abstract: A vertical dropped-weight impact test machine has a dropped-weight barrel vertically supported on upper and lower support brackets. The dropped-weight barrel is chambered to receive a dropped-weight assembly having a latch pin at its upper end, a damping unit in the middle, and a tup at its lower end. The tup is adapted for gathering data during impact testing. The latch pin releasably engages a latch pin coupling assembly. The latch pin coupling assembly is attached to a winch via a halyard for raising and lowering the dropped-weight assembly. The lower end of the dropped-weight barrel is provided with a bounce-back arresting mechanism which is activated by the descending passage of the dropped-weight assembly. After striking the specimen, the dropped-weight assembly rebounds vertically and is caught by the bounce-back arresting mechanism.

Abstract: An air conditioning unit for use in the cooling of persons includes a fan secured below the person's neck. A moistened foam necklace may be wrapped around the neck or a moistened foam pad otherwise positioned between the fan and the neck of the user. The fan of the air conditioning unit includes a frame, an electric motor mounted on the frame, a fan blade operably connected with the motor and rotatable by the motor for moving air, a battery or other power source operably connected with the motor for actuation thereof, and a switch operably connected between the battery or power source and the motor for controlling the actuation of the motor. Furthermore, the air conditioning unit includes a flexible element attached to the frame, the flexible element being constructed and arranged to be worn around the user's neck so that air generated by the moving fan blade moves against the neck area after being evaporatively cooled by the foam necklace or pad.

Abstract: A lace fastener has upper and lower jaws and a latch to selectively hold the jaws in their closed position. The lower jaw has an opening through which the lace is inserted into the fastener. The upper jaw is arced so that, in the closed position, the up sides of the jaws form an elliptical opening. The teeth of the jaws are curved slightly inwardly to accentuate the elliptical relationship and are in an underbite relationship. A plurality of fasteners may be fixed with their lower jaw openings aligned with selected eyelets or other form of laceholder so that a lace can be fed in normal criss-cross fashion through the laceholder. The lace can then be tautened, even with the latches closed, by drawing it through the opening in the lower jaw and out the elliptical up side opening. The lace is secured in the taut position by closing the latches with the lace between the teeth of the fastener. A bow knot may be used, but is not required.
