e v Fluid-working machine valve timing By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A fluid-working machine has a working chamber of cyclically varying volume, high and low pressure manifolds, and high and low pressure valves for regulating the flow of fluid between the working chamber and the high and low pressure manifolds respectively. A controller actively controls at least one said valve to determine the net displacement of working fluid of the working chamber on a cycle by cycle basis. At least one said valve is a variable timing valve and the controller causes the valve to open or close at a time determined taking into account one or more properties of the performance of the fluid working machine measured during an earlier cycle of working chamber volume.

e v Line voltage control circuit for a multi-string LED drive system By www.freepatentsonline.com Published On :: Tue, 18 Nov 2014 08:00:00 EST A line voltage control circuit for use with a multi-string LED drive system which provides a common line voltage for multiple LED strings that are connected to respective current sink circuits at respective junctions. An error amplifier receives the minimum junction voltage and a reference ‘desired junction voltage’ at respective inputs, and a voltage regulator outputs the line voltage in response to a voltage applied to a feedback input. A comparator toggles an output when the maximum junction voltage (Vmax) exceeds a reference limit (Vlimit). A multiplexer receives the error amplifier output and a fixed voltage at respective inputs and provides one of the signals to the regulator's feedback input in response to the comparator output. When Vmax>Vlimit, the fixed voltage is provided to the feedback input and the line voltage is reduced, thereby protecting low voltage current sinks from potentially damaging high voltages.

e v Wobble plate-type variable displacement compressor By www.freepatentsonline.com Published On :: Tue, 07 Apr 2015 08:00:00 EDT Disclosed is a wobble plate type variable displacement compressor that uses a constant velocity universal joint mechanism, which comprises an inner ring and an outer ring, balls that are held between guide grooves of the inner ring and the outer ring to transmit power, wherein a wobble plate is connected and fixed to the outer ring. In the compressor, the wobble plate is provided with a cylindrical part which extends in the axial direction of a swash plate, and in the relative rotation structure between the swash plate, and the wobble plate and the outer ring, the swash plate is supported to be able to relatively rotate only in relation to the wobble plate via a bearing interposed at least between the cylindrical part and the inner diameter portion of the swash plate, without being supported to be able to rotate relative to the outer ring. With this wobble plate type variable displacement compressor using the specified constant velocity universal joint mechanism, the relative rotation structure between the wobble plate and the outer ring, and the swash plate, can be improved, workability and productivity can be improved, and the cost and weight can be reduced.

The bead is supported by the two valve housing parts and is provided with an undercut at a radial inner side. Further, a membrane for installation in a membrane valve is provided. Full Article
e v Airflow control device for an automotive vehicle By www.freepatentsonline.com Published On :: Tue, 07 Apr 2015 08:00:00 EDT An airflow control device is mounted to the front end of an automotive vehicle and includes an upper air scoop section having a scoop channel disposed rearward of a bumper assembly and oriented to direct airflow entering a bumper intake opening toward an air-receiving powertrain component. A lower air dam section extends downwardly from the upper section to be positioned below a lower extent of the bumper assembly to deflect airflow away from an underside of the vehicle. Full Article
e v Electrical contact coupling for a track-borne vehicle, particularly a railway vehicle By www.freepatentsonline.com Published On :: Tue, 18 Feb 2014 08:00:00 EST An electrical contact coupling for a track-borne vehicle has a coupling housing and a protective flap articulated to the coupling housing. In order to ensure a reliable sealing of the coupling housing in the closed state of the electrical contact coupling, a seal is utilized which exhibits an upper sealing area running parallel to the axis of rotation and a lower sealing area running parallel to the axis of rotation. The upper sealing area associates with a sealing face aligned perpendicular to the housing end face and the lower sealing area associates with a sealing face aligned substantially parallel to the housing end face.

e v System and method for multi-phase voltage regulation By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT In accordance with one embodiment of the present disclosure, a multi-phase voltage regulator may comprise a plurality of phases, each phase configured to supply electrical current to one or more information handling resources electrically coupled to the voltage regulator. A controller may be electrically coupled to the plurality of phases. The controller may designate at least one of the plurality of phases as a first state phase, and designate each of the plurality of phases not designated as a first state phase as a second state phase. The controller may alternate the designation of at least two of the plurality of phases between a first state phase and a second state phase. Each first state phase may be configured to supply a first electrical current regardless of electrical current demand. Each second state phase may be configured to supply a second electrical current based on the current demand. Full Article
