Granted: 1999-10-12
Abstract: A system for recording and playing back multimedia events includes recording sources, a preprocessor, a delivery processor, and user control units. The recording sources each captures a continuous temporal record or track of the multimedia event and transmit the captured track to the source preprocessor where tracks are coded into digital blocks and digitized blocks of tracks received simultaneously are time stamped with the same relative time, and therefore synchronized in time. Tracks of the multimedia event are also compressed and preprocessed to generate other representations of the multimedia event, which further assist users in searching through the media event. The delivery processor services users' requests for multimedia events and delivers events to requesting users according to users' interactive commands. The delivery also generates stacked representations of the tracks of the multimedia event which representations provide visual cues to assist the user in conducting rapid and intelligent searches through the multimedia event. The user control unit receives requests and interactive commands from the user to be transmitted to the delivery processors and multimedia events from the delivery processor for presentation to the user.

Abstract: A system and method for identifying and processing individual patients among a set of patients includes storing position data representative of patient-unique arrangements of targets that are affixed to the patients for aligning a therapeutic radiation beam. Subsequent to the recording of the position data, a particular patient and/or the medical information of the particular patient can be identified by reimaging the targets or substitute targets on the particular patient to detect a correlation between the image data and the stored position data. The correlation may be used to register a patient, track the location of the patient within a multi-station facility, or facilitate treatment setup, such as beam-to-patient alignment, radiation configuration, and beam control.

A minor component containing of a high molecular weight water- soluble polymeric carbohydrate is dry-blended with a major component comprising of a low molecular weight water-soluble carbohydrate, sugar alcohol or food acid. Typically, the carbohydrate admixture comprises between about 15% to 40% high molecular weight carbohydrate material and at least about 40% low molecular weight carbohydrate, sugar alcohols or adipic, malic or citric acids or combinations thereof. A labile material like omega-3 oils or .beta.-carotene is combined with this substrate mixture. The dry-blended admixture is extruded so that the temperature of the material in the extruder is between about the glass transition state of the substrate and the melting point of the major ingredient. The free-flowing product is relatively non-hygroscopic and has a high fix.

Abstract: A spray nozzle of the type adapted to feed a liquid to a material being sprayed therefrom comprises a tubular spray conduit around which is arranged an annular feed port, this feed port being closed in a liquid-tight manner by resilient material openable by liquid pressure and whose degree of opening, and therefore the quantity of liquid fed to the material, rises linearly with increasing liquid pressure. Preferably, the resilient material is provided by a membrane ring (7) which is a flat ring with inwardly-tapering radial ridges (8b) raised thereon, the gaps between the ridges being filled with an elastomeric material, such that a series of resilient segments (9) is created. Under liquid pressure, the segments are compressed equally, giving a nearly completely annular flow of liquid into the material. The nozzle is particularly useful for the spraying of concrete, especially by the dry method.

Filed: 1998-11-03
Granted: 2003-06-24
Abstract: A system controls the pressure at which conditioned is to be provided to one or more zones to be heated or cooled by the conditioned air. The system actively computes a setpoint for the pressure with a location in a duct system upstream of where any of the conditioned air is to be provided to the zones. The setpoint is computed as a function of the positional statuses of dampers within the duct system that regulate the flow of the conditioned air to the respective zones. The actively computed setpoint is compared with a sensed pressure in the duct system in order to determine whether the pressure in the duct system needs to be changed.

Abstract: In order to vent a diecasting mould of a diecasting machine, it is proposed that the mould cavity and/or the pressure chamber are vented during the filling operation by a second venting valve, additionally to a first venting valve. The first venting valve is located in a venting channel portion that communicates with a venting channel leading out of the mould cavity. For operating the first venting valve, an impact transmitter is provided that is operationally connected to the first venting valve and that is exposed to and moved by the casting material advancing from the mould cavity to the venting channel. The second venting valve is operated by separate independent means and is closed before the mould cavity is completely filled. As a criterion for closing the second venting valve, the length of the path can be used along which the casting piston runs during the filling operation.
