Title: Storm resistant wave power generator
Filed: 2012-08-06
Abstract: At least one flexible balloon or bladder 1 floats on water 2 and is fluidly connected to at least one pipe 8. When waves flow over the balloon or bladder 1 a pressure is exerted causing it to deform and increase the pressure in the pipe 8 which can be used to drive an electrical generator or pump 5, eg by means of a turbine. The balloon or bladder 1 preferably has an inlet 3 and outlet 4 fitted with non-return valves to allow a continuous flow of air to a generator 5. The balloon or bladder 1 preferably self re-inflates after a wave. Preferably the fluid in the balloon or bladder is air 6, and the pump may feed a water reservoir which feeds an electricity generator as in a hydroelectric dam. There may be two or more balloon or bladders and pipes and there may be surplus pipe leading to the balloon or bladder and the pipe may be staked to the sea bed 7.

Title: Auto-focus image system
Filed: 2011-06-09
Abstract: An auto focus image system that includes a pixel array coupled to a focus signal generator. The pixel array captures an image that has a plurality of edges. The generator generates a focus signal that is a function of a plurality of edge-sharpness measures, each one measured from one of the plurality of edges. The generator may determine to reduce a relative extent to which an edge contributes to the focus signal on basis of a pair of shape measures of the edge that are measured from a plurality of sample-pair differences, where each sample-pair difference is a difference between a pair of samples of image data within a predetermined neighborhood of the edge. One of the shape measures may be the edge-sharpness measure of the edge.

Title: Control device for internal-combustion engines
Inventor: KRAMER MANFRED DIPL ING
IPC: F02B3/06
Filed: 1980-06-04
Granted: 1983-07-14
Abstract: A control apparatus for internal combustion engines is proposed, in which the adjustment range or the full-load position of a supply quantity adjustment member of the fuel metering apparatus is varied in accordance with the absolute pressure of the aspirated air in the suction tube of the engine in order to attain optimal combustion at the greatest possible torque. The control apparatus (FIG. 1) includes a pneumatic pressure converter and a pneumatic adjustment member. The pneumatic pressure converter, in a first pressure chamber, contains an evacuated diaphragm pressure box exposed to the aspirated air pressure (pL), which acts counter to a second diaphragm pressure box exposed in its interior to atmospheric air pressure (pA) and located in a second pressure chamber connected to a compressed air source. Both pressure boxes are connected via an actuation member supporting a valve member, and the valve member reduces the servo air pressure (pS) to a control air pressure (pSt) which is proportional to the absolute aspirated air pressure (pLK), this control air pressure actuating the diaphragm adjustment member functioning counter to a restoring spring and to atmospheric air pressure.

Patent DE-3267004-D1 (DE)
Title: Method of, and apparatus for damping of stepper motor using non-active windings
Inventor: WHITE JAMES NORMAN JACKSON
IPC: H02P8/00
Filed: 1982-06-22
Granted: 1985-11-28
Abstract: In a disk drive system which uses as stepper motor, overshooting of the desired final position is reduced by short-circuiting the windings of the stepper motor which normally remain open-circuit or are switched off. This short-circuiting provides a current path for any EMF induced in the unused windings. This effect is achieved by connecting a pair of transistors in parallel with each other and with each respective winding. The transistors are connected in opposite polarity to provide a short-circuit regardless of the polarity of the EMF across the windings. The transistors are connected to a microprocessor which is programmed such that the windings are selectively short circuited and the short circuits are applied at a predetermined time with regard to the step so that 'damping' is optimized. The microprocessor may be programmed to switch the transistors on and off as desired giving flexible timing to suit different conditions. One or more stepper motor steps may be treated in this manner.

Title: Retarding system of a gas compression relief type
Inventor: CAVANAGH MARK STEVEN
IPC: F01L13/06
Filed: 1982-12-21
Granted: 1986-04-10
Abstract: A hydraulic reset mechanism is provided for an engine retarder of the compression relief type. The mechanism includes a pin valve and senses the force required to hold open an exhaust valve. When this force has decreased substantially from the force required to open the exhaust valve initially, the pin valve is opened in the hydraulic system to release the hydraulic pressure and permit the exhaust valve to close. The mechanism thereby assures that the engine exhaust valves are closed, or substantially closed, prior to the normal opening of the exhaust valves at the end of the power stroke of the engine without affecting the retarding horsepower produced by the engine brake.
