Inventor: DASILVA MARIO
IPC: H01R13/66
Filed: 2009-04-06
Abstract: An impedance assembly is provided for a termination device, disconnectable connector, or other type of joint for an electrical connection, such as an elbow, to facilitate preventing improper installation. More specifically, an impedance assembly can include an obstruction member that help prevent the insertion of a stud into a female device, such as a bushing, unless the stud is properly inserted through the aperture of the lug of the cable assembly. The obstruction member can include a flexible and/or displaceable member that can be displaced by the lug of the cable assembly. Alternatively, an impedance assembly can prevent the rotation of a female member which rotates to receive the stud of a male device. The impedance assembly can include an element that is received in a cavity, groove, etc. of the female member for preventing the rotation of the female member unless the element is removed therefrom. For example, the element can be removed from the cavity, groove, etc. upon the displacement of a displaceable member operatively connected to the element, thus permitting the female member to rotate.

Title: Hall sensor temperature drift control
Inventor: KERLAIN ALEXANDRE
IPC: G01R15/20
Filed: 2007-08-30
Abstract: Disclosed are apparatus and methodology for providing approaches to remove or reduce thermal drift of the magnetic sensitivity of Hall sensor devices, to improve the stability of resulting signals of interest. Samples of a particular signal or signals of interest having improved stability make for advantageous use in conjunction with electricity meters. At the same time, associated designs and related components have greater simplicity, for reduced complexity in implementation. Among alternative embodiments, a gating structure selected of various present alternative designs may be used to partially cover, to an intentionally selected degree, an active area of a Hall sensor, so that a zero-drift supply current value may likewise be selected so as to satisfy other criteria which may be applicable to use of the Hall sensor. In other alternative embodiments, a gate structure is used which fully covers the Hall sensor active area, but a gate- control technique is practiced which is based on combined use with an external, relatively high resistance voltage-divider circuitry arrangement, again for eliminating temperature-based drift of the magnetic sensitivity of the Hall sensor arrangement, regardless of the end use to which such Hall sensor is applied.

Title: Pressure relief apparatus
Inventor: BRAZIER GEOF
IPC: F16K17/38
Filed: 2001-01-05
Abstract: A pressure relief apparatus includes a valve having a body. A shaft is rotatably disposed in the body and has an exterior end extending through the body. A plug, which may contain an internal passageway, is mounted on the shaft and is disposed in the fluid flowpath. The body is engageable with the system to expose the plug to the pressurized fluid so that the pressurized fluid acts on the plug to exert a torque on the shaft which is offset from the center line of the plug. The apparatus further includes a linkage assembly configured to translate the torque exerted on the shaft into an output force. A release device, such as a buckling pin or a magnet, is connected to the linkage assembly and is configured to release the shaft when the output force exceeds a predetermined limit. Preferably, the linkage assembly is adjustable to vary the magnitude of the output force corresponding to a given torque. A low torque seal secured in place by a retaining ring is disposed in the body to prevent fluid from leaking through the body past the plug.

Title: Signaling of multiple decoding times in media files
Inventor: WANG YE-KUI
IPC: H04N7/26
Filed: 2008-04-23
Abstract: The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.
