Abstract: A METHOD AND APPARATUS FOR RECEIVING SIGNALS IN A           MULTI-PATH ENVIRONMENT Abstract Signals from multiple signal paths are received using a multi-element antenna 20 and a beam-forming network 34. Signals from each of the antenna elements are sampled to form a sample vector. Several sample vectors are used to form an auto-covariance matrix. A singular value decomposition of the auto-covariance matrix is used to form three matrices. The first matrix is used to determine the number ofsignal paths and the second matrix is used to form several polynomials. The polynomial roots that are on or near the unit circle are used to determine points on the unit circle that are associated with each signal path. Each point on the unit circle is used to calculate weights for a beam-forming network 34 that forms a receive beam for each signal path. FIG. 3

Abstract: The noise from the effects of currents through distributed capacitances between electrical circuitry on an integrated circuit chip and the chip substrate is minimized, especially for analog circuitry mixed on the chip with digital circuitry.  The invention separates a plurality of bits in each digital word into a plurality (e.g. 2) of segments.  A first register off the chip latches the first bits in each word with a first clock signal.  A second register off the chip latches the second bits in each word with a second clock signal delayed from the first clock signal.  The first register bits are latched on the chip with the first clock signal by a third register.  The delayed second register bits are latched on the chip by a fourth register with the second clock signal or with a delayed first clock signal having the same delay as the second clock signal.  Substrate ties for the third and fourth registers may be connected to at least one, preferably a plurality, of bonding pads on the chip.  The bits from the third and fourth registers may be combined on the chip into a single word. Alternatively, the bits from the third register may be delayed on the chip by the delay of the second clock signal and combined with the bits from the fourth register.  In another alternative, the combined signals may be re-registered on the chip in a fifth register in accordance with a clock signal having the delay of the second clock signal.

IPC: G01R31/06
Filed: 1996-02-29
Granted: 2005-09-06
Abstract: A step down transformer power supply with short circuit protection which uses a minimal size transformer, as opposed to an energy limiting transformer. The transformer is mounted directly on a PC board without additional mounting hardware, and has a fuse in its secondary winding, which is required to pass a UL short circuit test, and is normally nonreplaceable. A low cost circuit limits the current output of the transformer such that the fuse is not blown, even under a shorted output condition, which would normally require replacement of the transformer. A rectifier circuit is coupled across the secondary winding of the step down transformer, and is coupled to a first terminal of a three terminal power regulator circuit which supplies a regulated stepped down voltage through a second terminal connected to a load. The third terminal thereof comprises a current/voltage limiting control terminal. A resistor is coupled in series with the load to sense the output current through the load, and is connected to the base of a transistor having an emitter, collector, and base. The collector and emitter of the transistor are coupled in series with the control terminal of the power regulator circuit, such that as the output current increases above a threshold indicative of a short, the output current of the power regulator is limited to prevent the slow-blow fuse from being blown.

Abstract: A joint of tubular casing with a pre-formed window in its sidewall, has a tubular sleeve fixedly attached to the interior of the tubular casing by a plurality of shearable set screws. The exterior surface of the sleeve is sealed to the interior surface of the tubular casing on opposing sides of the window. The window is filled with a fluid and then the window is covered with one or more layers of a composite material such as fiberglass. In use, the joint of tubular casing is run down to the depth of interest in an earth borehole, and then the window is oriented with respect to the formation of interest at the depth. The joint of tubular casing is then cemented in place, after which the tubular sleeve is retrieved by the use of a fishing tool causing the set screws to shear upon the upward movement of the fishing tool.  After the interior sleeve is retrieved, a whipstock is lowered into the cased borehole, until it is oriented and anchored therein. The assembly automatically fixes the axial and circumferential orientation of the whipstock within a surrounding casing joint and holds the assembly in place. Alignment and fixing of the whipstock ensures proper engagement and orientation of a drill bit with an access window formed in the casing wall. The assembly employs multiple spring loaded latches which register with and extend into corresponding receiving recesses formed on the inner surface of the casing joint. The recesses, which are spaced circumferentially around the interior of the casing joint, contain differing profiles which uniquely mate with corresponding profiles on the latches. The relative position of the latches with the recesses determines the amount of radial latch movement providing keyless anchoring and orientation of the assembly within the casing. Setting is positively confirmed with a simple rotational force on the setting string. The spring loaded latches release from anchored, oriented position in response to an upward axial force exerted by the drill string to provide a straight pull release of the assembly. Confirmation of correct axial location and proper circumferential orientation may be made by surface monitoring of the setting string weight and turning torque.

Granted: 1999-11-16
Abstract: The invention is a footrest support structure for attachment to the frame of a wheelchair.  A footrest is carried on the end of a telescoping leg pivotally engaged to a wheelchair frame.   The telescoping leg automatically extends as it is elevated, by means of a folding link that engages the two parts of the leg.  The link is engaged as well by a lever lock that  permits  the  first  arm to  slide  freely  in  a  first direction but not in a second direction until the lock is actuated.   The first arm of the folding link is pivotally engaged to the upper leg at a first pivot point intermediate the ends of the first arm and the leg,  respectively,  for pivoting the arm in a generally vertical plane.  The second arm is pivotally engaged at its lower end to the lower leg at a second pivot point.  The distance between said first and second pivot points extends as the footrest support structure is elevated, thus causing the leg to elongate.
