Abstract: A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the contactor assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression.

Abstract: Materials derived from cinnamon can be administered orally to humans or animals for the purpose of controlling blood glucose as well improving glucose tolerance. Controlling glucose metabolism is essential for those with impaired glucose metabolism as is the case for those with Type II diabetes where insulin function is not properly functioning. Such administration can also be used for the purpose of enhancing nutrient transport for purposes of athletic performance and controlling bodyweight and body fat levels. Similarly related, such administration can also be used for the purpose of enhancing creatine transport into excitable tissues such as skeletal muscle. The material can be administered as extracts of cinnamon and can be administered in a variety of ways including capsules, tablets, powdered beverages, bars, gels or drinks.

Abstract: A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to be secured in generally close proximity to the stationary contact. During communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with the stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. A pair of arc guides extend along the magnetic intensifier and, cooperatively with the magnetic force, ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor. Such a construction increases the operable range and lifecycle of the contactor by reducing the damage associated with propagation of the circuit termination arc.

Abstract: A method for labeling the pixels within a selected visual area of at least one image frame containing that visual area from a sequence of image frames stored in memory and operative to be displayed on an interactive display so that a user may subsequently select the selected visual area on a pixel accurate, frame accurate basis. To label the selected visual area within an image frame, the scene within that image frame is segmented to identify the selected visual area, each pixel within that selected visual area is then labeled with an area identifier which is unique to that selected visual area, and the pixels containing the area identifiers are mapped into an item buffer. The item buffer is then compressed and stored within a labeled portion of memory linked with the stored frame image from which the item buffer was derived.

Abstract: Apparatus and methods are disclosed for viewing low-birefringence structures within samples directly, with the eye, in real-time. The sample is placed between an entrance polarizer and analyzer polarizer, the transmission state of one of which is changed dynamically to create a modulated view of the scene; against this background, birefringent structures are visible because of their different appearance when modulated. Modulation rates of 4 or more states per second; use of 4 or more states, or even a continuum of states, which lie substantially on a latitude line on the Poincare sphere; and orientation of the polarization components to produce a uniform background; produce a clear view that does not produce operator fatigue. Broad-band wavelength operation spanning 50 nm or more, or the whole visible range, is achieved, and it is compatible with integration into other microscopy modes such as Hoffman relief contrast.

Abstract: An optical filter uses two or more reflective polarizers together with retarders to form birefringent filters with controlled transmission. The energy reflected by these polarizers is absorbed by one or more dichroic elements, which can be adjacent to a reflective polarizer; or spaced apart from it by one or more retarder elements. These dichroic elements act as dampers, so the energy of rays undergoing multiple reflections is markedly reduced or virtually eliminated, and high image quality is maintained. This provides a filter arrangement with enhanced spectral range, image quality, or greater extinction, or lower cost, compared to filters using dichroic or prism-type polarizers.

Abstract: An athermalized birefringent filter for shifts in center wavelength and in bandwidth incorporates fixed retarder elements such as quartz or film retarders, along with electrically-variable retarder elements such as liquid crystal variable retarder cells. A control mechanism determines the amount of thermal drift in the fixed retarder element and produces an equal change in the variable retarder element. The sign of the change depends on whether the variable retarder element adds its retardance with that of the fixed retarder element, or opposes it. This change compensates for the thermal drift of the fixed retarder element. Further, the variable retarder element is constructed to provide the necessary range of retardance adjustment for spectral tuning and thermal compensation over a target thermal range. The control mechanism ensures that, for any specified wavelength, the birefringent filter operates in the same order over the full target thermal range.
