Abstract: Embodiments of a Transistor Outline (TO) can package having an integrated Thermoelectric Cooler (TEC) and methods of manufacturing a TO can package having an integrated TEC are disclosed. In some embodiments, a TO can package comprises a TO header and a TEC on a surface of the TO header. The TEC comprises an insulation layer on a surface of the TO header, where the insulation layer has a thickness that is less than 100 micrometers and comprises one or more thermally and electrically conductive materials. The TEC further comprises a plurality of thermoelectric devices on a surface of the insulation layer opposite the TO header. The thin insulation layer, as opposed to a relatively thick bottom header of a stand-alone TEC, enables taller N-type and P-type legs for the thermoelectric devices, and thus a higher Coefficient of Performance (COP), within a given height for the TEC.

Abstract: According to one aspect, a hybrid heat transfer system includes a first thermally conductive path configured to passively transfer heat between a load having a load temperature (TL) and an ambient environment having an ambient temperature (TA), and a second thermally conductive path configured to actively transfer heat between the load and the ambient environment, the second path comprising a heat pump.

Abstract: A method of controlling the orbit of an inclined, eccentric geosynchronous satellite by maintaining its perigee location while simultaneously preventing a reference point on the orbit from moving too far relative to a normal position over the Earth. Doing this changes the semimajor axis of the orbit, which when perturbed away from the geosynchronous value, creates a drift rate relative to the Earth. To correct the argument of perigee and maintain the prescribed tolerance on ground track position, multiple maneuvers must be performed to control the drift rate. The relationship between maximum allowable velocity change and time between maneuvers is defined by the required correction to the argument of perigee and the allowable motion of the reference point.

Abstract: A device (and method) for securing a glove (or mitten) having two opposing ends and fastener for releasably fastening the opposing ends together to define the first strap as a continuous loop having a circumference extending over the glove around the wrist of the hand. A second strap is provided having a fixed end connected to the first strap and a free end which extends substantially perpendicular from a first part of the continuous loop of the first strap over the glove between two adjacent digits of the hand. The free end of the second strap has a fastener for releasably fastening the second strap to a second part of the continuous loop substantially circumferentially opposite the first part of the continuous loop. In the case where the glove defines a mitten, the above two adjacent digits are the thumb and index finger of the hand. The free end of the second strap of the device may further have a tapered width along a portion of the free end which extends between the two adjacent digits.
