Abstract: This invention relates to endless tracks and guide wheels used therewith to propel track laying vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved rubber track design and guide wheel allowing the endless track to be driven more efficiently at highway speeds. The track is made from a polymer adapted to travel over a drive sprocket, a plurality of guide wheels and a tensioning wheel, the track having a first exterior ground engaging surface and a second interior drive sprocket engaging surface, the track comprising: a carcass portion in which reinforcing means are embedded into the polymer; a plurality of tread lugs disposed on the first engaging surface; a plurality of drive lugs disposed on the second engaging surface and a plurality of guide horns disposed on the second engaging surface. The guide wheels comprise two track supporting outer surfaces between which the guide horns are adapted to pass, each outer surfaces defining a first gap between it and the guide horns and a second gap between it and the drive lugs, the second gap being greater than the first gap.

Abstract: A method of self-discovery and self-calibration is provided for allowing arbitrary placement of audio and video components in a multimedia conferencing system. In particular, one or more markers are provided on the audio components (e.g. microphone arrays, etc.) that are detectable by the video components (e.g. cameras). A unique signature (e.g. flashing sequence, color, etc.) characterizes each marker so that its exact location relative to the camera may be calculated. A self-calibration operation is then performed to relate, regulate and standardize dimensions and locations in the conferencing environment to the video system.

Title: Sleeve-like knitted structure for use as a castliner
Inventor: SCHULTZE CLAUDIA
IPC: A61F13/10
Filed: 2004-06-25
Granted: 2014-01-14
Abstract: A castliner in the form of a three-dimensionally knitted sleeve comprises a microdenier yarn, and/or a spandex yarn, in particular, a spandex yarn having a flatter stress-strain curve than traditional spandex yarns. The use of the microdenier yarn contributes to the superior cushioning effect. The stretch and recovery properties of the particular spandex yarn contribute to superior fit and reduction of pressure points on the limb or body part to which the castliner is applied. Furthermore, the castliner is rendered water resistant and has significantly improved antimicrobial properties, both of which reduce incidents of skin irritation and unpleasant smell. As a result, the patient wearing the castliner of the invention is able to bathe and get wet without otherwise replacing the hard casting and castliner after such events.

Granted: 2013-09-24
Abstract: The invention relates to a liquid working substance flow (13), the pressure of said flow being increased and the flow itself being subdivided into a first partial flow (16) and a second partial flow (17). The first partial flow (16) is partially evaporated with heat from a heat source (20), and the second partial flow with heat from a working substance flow (11) with a low surface tension. The two partial flows are then combined and produce a gaseous working substance flow (10) with heat from the heat source (20). The surface tension of said gaseous flow is reduced and the energy thereof converted into a usable form. The working substance flow (11) with a low surface tension is condensed, thus producing the liquid working substance flows (13). According to the invention, the first partial flow (16) and the liquid working substance flow (13) are essentially at the same temperature. In this way, the heat of the heat source (20) can be better used, thus increasing the efficiency of the cycle.
