    摘要： Method of detecting a leak in a fuel system comprising a fuel tank and an orifice with a controlled section between the tank and the atmosphere, according to which a) the controlled section is set to a value A1 at a time T1 and a pressure differential Δp1 between the inside of the tank and the atmosphere is measured at least after an interval of time ΔT from T1, for a constant fuel flow out of the tank; b) the controlled section is set to a value A2 at a time T2 and a pressure differential Δp2 between the inside of the tank and the atmosphere is measured at least after the same interval of time ΔT from T2, for the same constant fuel flow; c) a ratio of the pressure differentials Δp1 and Δp2 is computed and is compared to a reference pressure differential ratio APL obtained with the same fuel system but comprising a calibrated leak.

    摘要： An adjusting mechanism alters the heel height on a prosthetic foot, and works independently of any articulating ankle joint or foot style, without changing the original dynamic alignment of a prosthetic leg. In a two chamber hydraulic closed system—a fluid material is allowed to flow through the two chambers by means of pistons that push the fluid material equally from one chamber to another until the desired heel height is obtained. Once the correct position is obtained, the ports are closed by means of a push button stop, which closes the ports and stops all transfer of fluid between the ports holding the heel in position during use.

    摘要： A vehicle fuel system for an internal combustion engine comprises a fuel tank, at least one fuel system component, at least one sensor (4, 5, 6) and a fuel system control unit (FSCU). The FSCU (2) is different from an engine control system (1) and has means for controlling functions of the fuel system. It is connected with at least one fuel system component to send signals or receive signals from it. It is also connected to at least one sensor (4, 5, 6) that sends signals to the FSCU (2) and/or the engine control system. It is adapted to electronically communicate with the engine control system. This FSCU (2) is external to the fuel tank.

    摘要： An image monitoring system uses wireless communications to transmit images for security monitoring. The system includes a central controller (105) and a plurality of digital still camera units (110) operatively connected to the central controller (105). At least one of the camera units (110) includes an image sensor (215), a motion detector (220) that causes the image sensor (215) to receive image data when motion is detected, a micro controller (205), and a first nonvolatile memory operatively connected to or included in the micro controller (205). The micro controller (205) determines whether received image data should be transmitted to the central controller (105), and the central controller (105) determines whether received image data should be transmitted to a monitoring station (115). The camera units (110) may further be used as standalone units as replacements for motion detectors in existing security systems.

    摘要： In one embodiment, the present invention includes a method for performing an operation in a processor of a uniprocessor system, initiating a write transaction to send a result of the operation to a memory of the uniprocessor system, and issuing a global observation point for the write transaction to the processor before the result is written into the memory. In some embodiments, the global observation point may be issued earlier than if the processor were in a multiprocessor system. Other embodiments are described and claimed.
