Granted: 2004-10-12
Abstract: An engine control system is disclosed having a unit for providing signals indicative of the position of an engine throttle member. The unit comprises a housing assembly associated with an engine throttle member and containing a stator assembly and a rotor assembly. The rotor assembly moves relative to the stator assembly as the throttle member moves. The rotor and stator assemblies are electrically coupled together for producing first and second continuously variable, ratiometrically identical signals whose values depend upon the throttle member position. The first signal is delivered from the housing assembly for use in controlling the engine operation. Processing circuitry processes the second signal for producing a throttle' position validation signal having a first value when the throttle member is in an engine idle range of positions and a second value when the throttle member moves beyond the idle range of positions. If the first signal and the validation signal signify incompatible throttle member positions the engine speed is limited to "idle."

Granted: 2007-05-22
Abstract: For improving mechanical characteristics of a segment of an aged optical glass fiber, the segment is retained between clamps, e.g. in a conventional splicing machine. Then the segment is heated to a high temperature in the vicinity of the softening temperature or melt temperature of the glass material of the fiber by means of an infrared light beam from a carbon dioxide laser or by an electric arc generated between the welding electrodes. In particular, the tensile strength is increased considerably by this procedure, what allows that the heated segment can be handled and exposed to the operative steps required for splicing the fiber to another optical fiber. Then also old fibers arranged in the ground can be repaired and spliced, and it is not necessary to replace whole lengths of old fibers.

Title: Method for providing parity in a raid sub-system using a non-volatile memory
Inventor: HITZ DAVID
IPC: G06F11/10
Filed: 1995-12-21
Granted: 2008-10-07
Abstract: The present invention is a method for providing error correction for an array of disks (828) using non- volatile random access memory (NV-RAM) (816). Non-volatile RAM (816) is used to increase the speed of RAID recovery from a disk error(s). This is done by listing of all blocks for which the parity is possibly Inconsistent. This list of blocks is much smaller than the total number of parity blocks (820) in the RAID. The total number of parity blocks (820) in the RAID (828) is in the range of hundreds of thousands. Knowledge of the number of parity blocks that are possibly inconsistent makes it possible to fix only those few blocks, identified in the list, resulting in a significant time savings. The technique for safely writing to a RAID with a broken disk is complicated. In this technique, data that can become corrupted is copied into NV-RAM (816) before the potentially corrupting operation is performed.

Title: Acquisition method and system of spreading code
Inventor: SAWAHASHI MAMORU
IPC: H04B1/707
Filed: 1996-06-12
Granted: 2007-03-27
Abstract: Performing respective multiplications (24) of an I and Q channel signals by a spreading code replica, integration (25) over one spreading code period, and square-law detection (26) of the integrated signals to remove data modulation components and residual carrier frequency components. The square-law detected signals are added (27) to obtain signal power over one spreading code period while updating the clock phase of a digital control clock generator (30). The information of power is stored in a memory in an acquisition mode controller (29), and the clock phase of the digital control clock generator 30 is fixed at the spreading code replica phase at which a maximum correlation detection power over one spreading code period is obtained.      Subsequently, a confirmation mode is started for confirming the spreading code acquisition phase. By thus providing the confirmation mode of the spreading code acquisition, the acquisition can be established in a short time with a low error acquisition probability, thereby enabling a tracking mode to be started soon.

Title: Apparatus and method for actively cooling instrumentation in a high temperature environment
Inventor: FLORES AARON G
IPC: E21B47/01
Filed: 1997-05-09
Granted: 2002-03-26
Abstract: An apparatus and method are disclosed for actively cooling instrumentation, in particular electronic circuits, in especially, high temperature environment. This apparatus has a tank containing a cooling agent, a heat exchanger to transfer heat from the instrumentation to the cooling agent, a compressor and a tank to hold cooling agent removed from the first tank. In this operation, the cooling agent tank is located in close proximity to the instrumentation. As the instruments generate heat, the heat is transferred through the heat exchanger to the cooling agent. The cooling agent boils and vaporizes from the heat and is pumped out of the tank by a compressor. As the cooling agent vaporizes and is pumped out of the tank, heat contained in the cooling agent is transferred out of the tank as well. The rate at which the vapor is pumped out of the tank controls the temperature of the cooling agent in the tank. The vapor is compressed under pressure and pumped to a storage tank where the vapor condensesback to a liquid.
