Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

Abstract: A multiple battery system and method for starting internal combustion engines, such as on a boat or vehicle, and for powering auxiliary functions that operate primarily when the engine is not running is disclosed. A first battery is used for starting the engine. A second battery is used to power the auxiliary features associated with the boat or vehicle primarily when the engine is not running. The first battery, referred to as the starter battery, is a high output battery that produces high bursts of energy for limited amounts of time. The second battery, referred to as the auxiliary battery, has a low power output over a fairly long period of time, is capable of being completely drained without harming the battery, and is capable of being fully recharged. The starter battery and the auxiliary battery are connected by a circuit that has an on/off switch controlled by an electronics control module. The auxiliary battery is always on line in the circuit.

Abstract: An engine block mount for use in holding engine blocks in a secure manner during cylinder boring is disclosed. The engine block mount includes an electromechanical clamping system that has a hydraulic system for balancing the pressure exerted on an engine block. The engine block mount can also include an open table top that allows a variety of boring tools to be utilized. The open table top version of the engine block mount includes sliding parallels which are secured in place during operation of the engine block mount by the hydraulic system.

Abstract: Apparatus and method for resurfacing the cylinder head of an internal combustion engine as by grinding a minimal amount of material from the cylinder head along a joining surface of the cylinder head in a grinding machine including a grinding wheel which traverses a grinding plane. The cylinder head is attached to a locator assembly having locator surfaces for coacting with the joining surface of the cylinder head and with support surfaces for supporting the locator assembly and the attached cylinder head in a grinding position relative to the grinding plane, and the cylinder head is secured in place in the grinding position for subsequent detachment and removal of the locator assembly to expose the joining surface of the cylinder head to the grinding wheel of the grinding machine for completing the resurfacing operation.

Abstract: Dynamic imaging microellipsometry (DIM) is a rapid full-field imaging technique for high resolution studies of thin-films. The DIM concept is based on radiometric polarizer, compensator, specimen, analyzer (PCSA) ellipsometry combined with video and image processing techniques. The theoretical basis for this approach is developed using the Jones vector and matrix formalism. Basic systems design is presented with error model predictions of ellipsometric accuracies better than 0.1.degree. for full-field .psi. and .DELTA. images captured in a few seconds with spatial resolution under 10 microns.

Abstract: A method for producing desired changes in a beam of coherent light radiating at .lambda..sub.1, comprising the steps of (a) splitting a beam of coherent light radiating at .lambda..sub.1, correcting one of the beams to achieve a desired wavefront and recombining this beam with the first, where a record medium (I) is placed such that the beams are separated by an angle determined by Bragg's law and the line spacing of the interference pattern formed by the two beams; (b) developing the first medium such that a diffraction grating of spacing d.sub.1 is recorded in a material, specifically sensitive to .lambda..sub.1, which will become the master; (c) illuminating the master with a second wavelength, .lambda..sub.2, selected by choice of a second medium which possesses very high diffraction efficiency. The second beam is split into two parts. The first is directed to the master. This diffracted order is recombined with the second beam.
