Abstract: The system and method taught herein allow a user to quickly determine how much inventory of a particular type is stored in nearby containers. Rather than inspect each container individually, a user need only scan the area for nearby containers. Each container will respond with its unique identifier and the number of items it contains.

Abstract: A thermal recording material having a heat-sensitive color-forming layer that contains a phosphate modifier in addition to an activator and lueco dye can provide good imaging. The phosphate modifier such as unsubstituted dibenzyl phosphate can be paired with an activator such 3-(4-hydroxyphenyl)propionic acid to provide an environmentally friendly thermal recording material.

Abstract: An LED spotlight is made with at least one light emitting diode and a lens placed forward of the light emitting diode to collimate the light from the light emitting diode into a beam. The light emitting diode is preferably a type with a nominal power of at least 1 watt, requiring heatsinking, and having a nominal radiation pattern width of 100 degrees or more. The lens is preferably concavo-convex. The lens can have a thickness less than the distance between the rear surface of the lens and the light emitting diode. The LED spotlight can be mounted on headwear that would be worn on a person's head. The LED spotlight can be in the form of a flashlight. The LED spotlight can be in the form of an inspection lamp suitable for causing visible fluorescence of fluorescent materials, such as leaks of fluids that have suitable fluorescent dyes.

Abstract: Work light has LEDs that require heatsink. Desired radiation pattern achieved by using optical components designed to produce beam or LEDs may have beams in different directions. Radiation pattern of LEDs may be changed by refractive-reflective optics or by convex lenses. Convex lenses may be hemispheres, other planoconvex shapes, concavo-convex shapes, or other shapes. Curved surfaces on any lenses may be spherical or aspheric. Ballast to operate the LEDs from line voltage AC or low voltage DC. Work light may contain batteries. The work light may be mounted on a stand. May have accessory mount. May have charging station. May have a paging transmitter to activate a paging receiver in work light. May have openings for heat transfer from heatsink to ambient air external to light.

Abstract: A method and system for the simultaneous high resolution display of multiple virtual DOS applications within a data processing system. The data processing system preferably includes a processor, a memory coupled to the processor and a display device coupled to the memory and processor. Multiple programs operating within the data processing system under the control of an operating system are capable of outputting multibank high resolution graphic displays. Each time an application which is either operating as a background task or displayed within a graphics applications window attempts to write to the display device the display data is written to a logical video buffer which is designated within a portion of the memory within the data processing system. A bank management function is provided in association with the logical video buffer and permits multibank high resolution graphic displays to be simultaneously maintained for multiple virtual DOS applications.
