Abstract: A tool for disengaging electrical connectors includes a central body section with disconnecting prongs projecting from the opposite ends thereof. The prongs are offset relative to the plane of the body section but extend in the same direction so that one set of the prongs forms an arcuate surface which facilitates the use of the prongs to disengage connector sections.

Abstract: A method for measuring relative position of fixed or slow-moving points in close proximity comprising: receiving a set of satellite signals with a first receiver corresponding to a first position; receiving a related set of satellite signals with a second receiver corresponding to a second position; and computing a position of the second position based on at least one of code phase and carrier phase differencing techniques. At least one of: a clock used in the first receiver and a clock used in the second receiver are synchronized to eliminate clock variation between the first receiver and the second receiver; and the first receiver and the second receiver share a common clock.

Abstract: A set of tools for installation and a set of tools for removal of studs from a work piece are disclosed. The installation tools include body member with a removable bearing that can be set against the head of a stud that is to be installed in a workpeice. The stud removal tools include a pair of body members which are each mounted on the stud to be removed and tightened against one another so that one of the body members may be rotated to effect removal of a stud.

Abstract: A tool for removal of a vehicle water pump, includes a cylindrical metal hollow member with a transverse butt plate welded at one end and teeth formed at the other end to engage tangs on a water pump so that the tool may be rotated to release a water pump from a housing. The teeth are especially constructed to ensure proper engagement thereof with the water pump tangs to effect removal from the water pump housing.

Abstract: A wrench set includes a drive handle with an impact end and a drive end. The drive end engages a drive wrench having a slot which receives the drive end of the drive handle. The opposite end of the drive wrench includes a laterally projecting or transversely projecting drive socket connection for attachment of any one of a set of sockets.

Abstract: A method of measuring phase of a pseudorandom (PN) sequence of chips, the method includes: generating a reference model exhibiting a reference phase, the reference phase adjustable to facilitate alignment with the phase of the pseudorandom sequence; establishing a plurality of pulsed-windows over which a plurality of samples of the pseudorandom sequence are collected for a selected accumulation interval; and accumulating the plurality of samples for each pulsed-window of the plurality of pulsed windows to form a plurality of accumulated sums. The method also includes: compensating each accumulated sum to form at least one compensated sum, if a number of level transitions and non-transitions of the pseudorandom sequence is not equal; and combining the compensated sum to determine a phase error from the plurality of compensated sums, the phase error corresponding to a phase difference between the reference phase and the phase of the pseudorandom sequence.

Abstract: A method for locking the sprockets or gears of a dual overhead camshaft engine in a fixed position includes two spaced bars with studs for engaging against the inside rim of the sprockets and a means for adjusting the spacing of the bars to frictionally maintain the sprockets in a locked position against the inside rims.

Abstract: A tool for determining the continuity of an electrical circuit for an internal combustion engine includes a single body member with male connectors projecting from the opposite ends and a lead wire having a 90° connection boot at one end and an inline connection boot at the opposite end is useful for attachment to the heads of spark plugs regardless of their orientation in an engine block.

Abstract: A manual trigger actuated automotive hose clamp release mechanism includes a flexible cable in a flexible tube. The cable and tube are attached respectively to opposed jaws designed to engage the end tabs of an automotive hose clamp and effect release of the hose clamp in response to movement of the cable relative to the tube. Mechanical advantage is gained by use of the manual trigger mechanism connected to the tube and cable in a manner enabling movement of the telescoping cable relative to the tube through which the cable extends thereby effecting movement of the jaws to release a hose clamp.

Abstract: A technique of accurately determining the relative position between two points using carrier phase information from receivers capable of making code and carrier phase measurements on signals transmitted from GPS satellites as well as signals transmitted from WAAS, EGNOS, MSAS or other Wide Area Augmentation System satellites (hereafter referred to simply as WAAS satellites). These signals are processed by a receiving system to determine relative position, for the purpose of surveying or otherwise, with the accuracy of carrier phase measurements being obtained. Signal processing similar to that used in existing GPS carrier phase based relative positioning receivers is used with WAAS signals as well. Benefits include faster and more reliable integer ambiguity resolution, protection from cycle slips and loss of sufficient satellites, and possibility of extending the operating range by allowing increased separation of reference and base receivers by incorporating ionospheric models provided by WAAS.

Abstract: A technique of accurately determining the relative position between two points, in real-time, using a single GPS receiver that makes measurements of signals transmitted from GPS satellites. A technique is applied where differential correction terms are computed as a location at an instant of time, and then applied to further times, after applying atmospheric delay adjustments, so that the position of the GPS receiver is determined accurately relative to the position at the original instant of time.
