Abstract: A method and system controls motion of an armature 112 of a fuel injector 100. The armature moves between an open coil 118 and a close coil 116 of the injector. Acceleration current of a certain polarity is applied to the open coil 118 with the armature disposed at the close coil 116. De-latching current of a polarity opposite of the certain polarity is applied to the close coil 116 to release magnetic latch on the armature thereby accelerating movement of the armature towards the open coil 118. Deceleration current is applied the close coil 116 thereby decelerating the armature prior to reaching the open coil. Latching current of the certain polarity is applied to the open coil 118 prior to or just after impact of the armature 112 with the open coil 118 to magnetically latch the armature to the open coil 118 thereby reducing bounce of the armature at impact.

Abstract: A method and associated algorithm for controlling and optimizing the temperature of a device under test (DUT) through calculation of a moving setpoint which varies from the user-specified DUT core temperature. The method generally comprises (i) calculating a system operating range based on limits imposed by the DUT, associated temperature control system, and thermal conditioning equipment; (ii) determining the allowable operating range for the DUT based on permissible DUT stress and DUT core temperature; and (iii) calculating a control setpoint based on DUT and conditioning system temperature data, one or more pre-selected setup factors, and the system and DUT operating ranges. In another aspect of the invention, variable temperature differential limits are imposed on the CSP as a function of DUT core temperature in order to mitigate thermal shock to the DUT. Methods and apparatus for latent temperature control are also disclosed.

Abstract: A sheet of fin stock is lubricated by a roller coater having first and second lubricant-applying rollers adapted to engage respective opposed first and second sides of the sheet and to apply a first synthetic lubricant to both sides of the sheet as the sheet is pulled through the roller coater. The lubricated sheet is then formed into a plurality of coil fins by a conventional fin press. The first synthetic lubricant is devoid of petroleum ingredients and is water soluble. The first synthetic lubricant forms a hydrophilic coating on the fins. The fins are assembled with a plurality of hairpin tubes to form the coil. A second synthetic lubricant is introduced into each of the tubes prior to bending.

Abstract: A computer keyboard template system which utilizes a tray device capable of being disposed in juxtaposition to the keyboard keys of a computer input terminal. The tray device is comprised of a base section capable of being disposed on the input terminal housing and a tray which is adjustably positionable with respect to the base. The tray is designed to receive a number of keyboard templates such that any one keyboard template may be selected and located in the forwardmost position on the stack of templates within the tray and in a position to be adjacent to the function keys of the computer input terminal. Thus, and in a preferred embodiment, the selected template is located adjacent to a row of keys, such as the upper row of function keys, on the keyboard of the computer. In this way, the user of the system will be able to quickly and easily select the proper keys for selected operations in accordance with the instructions on the template.
