Abstract: In general, this disclosure relates to techniques for sealing, or pinching, high-pressure fluid tubing (e.g., braided tubing) that may be used to deliver medical fluid from a powered medical fluid injection device, such as an injector that delivers contrast media and/or saline during angiographic or computed tomography (CT) procedures. In some cases, one or more low-friction, solenoid-based pinch valve mechanisms may be used. One example powered medical fluid injection device comprises an injector head and at least one pinch valve mechanism that is coupled to the injector head. The at least one pinch valve mechanism comprises a plunger, a reciprocating arm driven by the plunger, and a tube pinching area. The at least one pinch valve mechanism, when deactivated by the injector head, is configured to cause the reciprocating arm to pinch fluid tubing that runs through the tube pinching area.

Abstract: A food processing system 10 comprising a cooking apparatus 12 and a cooling apparatus 14. The apparatus 12, 14 are similar and are configured for processing sausages which have casings which are fragile and easily ruptured. The apparatus 12 comprises a processing vessel 16 for containing a cooking liquid, a feed chute 18, a guide means in the form of jets 56.1, 56.2 and 56.3, a screw conveyer 22 and a discharge conveyer 24.

Abstract: A radar includes a transmitting antenna and receiving antenna formed by an array of radiant elements. Antenna beams are calculated in P directions by a BFC function. Detections of a target by secondary lobes of the beams are processed by an algorithm comparing levels received in a distance-speed resolution cell, a single detection at most not being possible for each distance-speed resolution cell. Processing means use the assumption that there may probably be more than one echo with a signal-to-noise ratio that is sufficient to be detectable, for a given resolution cell of the radar, either in speed mode or in distance mode, or, alternatively, a distance-speed depending on the processing implemented; and, if there is more than one echo detectable for each resolution cell out of the plurality of beams formed by BFC, only the echo and BFC that obtain maximum power or maximum signal-to-noise ratio are/is considered valid.

Abstract: A semiconductor assembly is described with a thin metal oxide layer interposed between a transparent conductive oxide and an amorphous silicon layer, along with methods for making this structure. The metal oxide layer has a refractive index or range of refractive indices intermediate between that of the transparent conductive oxide and the amorphous silicon layer, and thus tends to reduce reflection at the interface. Such a layer can be used at the light-facing surface of a light-sensitive device such as a photovoltaic cell to maximize the amount of incident light entering the cell. Titanium oxide is a suitable metal oxide, and has a refractive index between those of silicon and of both indium tin oxide and aluminum-doped zinc oxide, two common transparent conductive oxides.

Abstract: A network traffic shaper adjusts the rate of data flowing from a packet source to a packet sink responsive to priority assigned to the packets pursuant to their ability to match a series of filters. Each packet is applied to a queue depending on its classification. The packets are read from each queue in accordance with a queue reading policy. Singular spectrum analysis of the traffic load produces a set of vectors that capture the spectral bases of the traffic state. These vectors are associated with the bandwidth demanded by the traffic, a relationship that is recorded in a queue/time/eigenvector/bandwidth/control table. Samples of the current network load are compared with previously recorded vector bases to reveal how similar the current traffic state is to previous traffic states, which in turn predicts the traffic's bandwidth needs for the immediate future. The queue reading regime is updated in response to this prediction.
