Abstract: In some implementations, a method performed by data processing apparatuses includes receiving, from a requestor device, an item location request for an item. Map information is received for a mapped space in which the item is located. Item location coordinates are received corresponding to locations within the mapped space at which the item has been previously selected or scanned. The item location coordinates are mapped with respect to the mapped space, and a plurality of clusters are determined for the item location coordinates. For each cluster, a representative location of the cluster is determined. One of the clusters is selected, based at least in part on its representative location, and an estimated location of the item is provided to the requestor device, based at least in part on the representative location of the selected cluster.

Abstract: An ice chest (a.k.a. portable cooler) rack designed to keep meats and/or other goods dry while inside the ice chest. The intent of the design is to keep game and/or domestic meats and/or other goods from getting “freezer burned”, and/or becoming water logged from coming into contact for periods of time with dry ice, ice, and/or water/liquids caused from melting/spillage. It has also been shown that this will prevent premature spoiling of products due to water logging. The present invention may be configured in a variety of different ways and may be constructed from a multitude of different materials including stainless steel, wood, extruded or molded plastics, various metals, aluminum, all with satisfactory results.

Abstract: A plurality of temperature dependent focal plane arrays operate without a temperature stabilization cooler and/or heater over a wide range of ambient temperatures. Gain, offset and/or bias correction tables are provided in a flash memory in memory pages indexed by the measured temperature of the focal plane arrays. The memory stores a calibration database, which is accessed using a logic circuit which generates a memory page address from a digitized temperature measurement of each of the focal plane array. The calibration database is comprised of an array of bias, gain and offset values for each pixel in the focal plane array for each potential operating temperature over the entire range of potential operating temperatures. The bias, gain and offset data within the database are read out, converted to analog form, and used by analog circuits to correct the focal plane array response.

Abstract: A potting compound for use in the fabrication of fiber optic gyro sensor coils utilizes a silver-filled silicone base to reduce gyro sensitivity to changes in heat rate and thereby improve gyro performance during warm-up and periods of thermal cycling.

Abstract: An electronic film cartridge includes a can section that defines an outer contour and is used to hold electronic components, and an imager assembly. The outer contour is configured so as to not completely depress at least one sensor mounted to the film compartment of a photographic camera into which the film cartridge is to be inserted. The electronic film cartridge is also configured to fit within different cameras with different dimensions between the film can area and the aperture.

Abstract: A thermoelectric cooler for cooling a sample of hot, continuously flowing gas involves a mechanical heat flow path passing from the flowing gas through a heat-exchanging tube channeling the gas, a heat-conductive block housing the tube, a thermoelectric element having a cold side abutting the block, a heat sink abutting a hot side of the thermoelectric element, and cooling air streams passing through slots in the heat sink. The heat sink is a unibody, jointless metallic body having relatively thin fins defining the slots. A high pressure blower drives turbulent air streams through the slots of the heat sink, and a thermal switch is disposed on the heat sink near the hot side of the thermoelectric element.
