Patent CA-2120455-C (CA)
Inventor: WILSON STANLEY EDWARD GEORGE
IPC: G01C19/08

Granted: 2004-11-09
Abstract: An improved electro-mechanical inertial rotation sensor comprising a rotor which spins at substantially constant speed with respect to an inertial frame of reference. A pickoff generates a signal relating the rotational position of the rotor relative to the apparatus. A phase comparator compares this pickoff signal to a reference signal relating the rotational position of the rotor relative to a fixed orientation in an inertial frame of reference, Changes in phase between the two signals indicate changes in orientation of the apparatus with respect to the inertial frame of reference. In one embodiment, the rotor is driven through an Eddy-current coupling and simultaneously braked by an Eddy-current brake, in a matched torque drive. To generate an accurate reference signal, the rotations of the rotor with respect to the inertial frame of reference are accurately determined using parallel measurements from a similar rotor, used as a test rotor. This test rotor is mounted in a pivot and during operation of the apparatus its axis is alternately oriented so that the test rotor's direction of rotation is alternately in the same direction of rotation (as the primary rotor) and in the opposite direction of rotation. In another embodiment, the rotations of the rotor with respect to an inertial frame of reference are determined using an optical rotation sensor mounted within the rotor. In a second mode of operation, a test rotor is used to determine the rotations of a vehicle or a body, such as the Earth, which maintains a substantially constant speed with respect to an inertial frame of reference:

Title: Tailored error protection
Inventor: JOHNSTON JAMES DAVID
IPC: H03M13/35
Filed: 1994-05-31
Granted: 1999-01-19
Abstract: A method of tailored error protection coding is disclosed. An illustrative coding method according to the present invention concerns encoding a first signal and a second signal to provide error protection for the signals, wherein the first signal requires greater error protection than the second signal. According to the method, the first signal is encoded with a first error protection code. The encoded first signal is then combined with the second signal. The combination of the encoded first signal and the second signal is further encoded with a second error protection code to generate a combined error protected signal, wherein the firstsignal is coded with both the first and second error protection codes. A second embodiment concerns the use of separate coders which apply different error protection codes to two signals. The two encoded signals are then combined into a single signal.

Abstract: For sealingly joining an underroof to a skylight or another roof installation a fitting collar is provided comprising a film element (7, 8) with a substantially U-shaped plane configuration with a cutout, at the sides of which there are flange parts (9, 10) for attachment of the fitting collar to mutually adjoined exterior sides (1-4) of the main frame structure of the window or the roof installation, in such manner that the film element is brought to extend substantially in parallel with the roof surface, in order to connect with adjacent parts (5, 6) of the underroof. The fitting collar can be manufactured in a simple manner, in that there in two overlapping lengths of film is produced transversal welds, at distances corresponding to a prescribed main frame width, whereby an obliquely extending part of each weld is formed with two parallel welded seams, while there in the edge zones at the opposite side edges of the lengths of film in extension of one and the other, respectively, of the two parallel welded seams are produced welded seams, which are perpendicular to the side edges. The collar elements are then separated by cutting along the cutting lines (22) between the parallel welded seams and parallel to the welded seams perpendicular to the side edges, and the collar is completed by cutting one length of film along the mid line between the welded seams with a subsequent bending upwards of the attachment flange parts.

Granted: 2003-09-23
Abstract: An apparatus for locating obscured conduits (28), such as buried cables, employs a novel signal processing technique to increase the sensitivity of the apparatus, particularly in congested areas. The cable locating apparatus (10) is similar to prior art dual-peak detection devices which compare signals from two parallel induction coils (12, 14), but a phase shift is introduced into one of the signals prior to the caparison. This phase shift serves to minimize the effects of said minima in the response curve of prior art dual-peak devices. This effect is enhanced by adding a gain mismatch to the two detected signals. The locator (10) preferably operates with analog signals to reduce expense.

For each roll (4), a required number of such stop gages (6), located in the rolling path of the roll, is selected to operate, while the rest of the stop gages are left in their home positions. In this fashion, each roll (4) can be stopped individually even when the rolls move simultaneously and, moreover, the stopping force can be adjusted separately for each roll.

Abstract: A peripheral controller interconnect/industry standard architecture (PCI/ISA)bridge is coupled between the PCI and ISA buses in a computer system. A PCI master in the system asserts address and address parity information on the PCI bus to initiate a master- slave transaction over the PCI bus. The bridge includes logic for comparing the address and the address parity information and generating an address parity error signal when there is an address parity error. The bridge also includes a PCI slave that receives the address parity error signal and generates a target-abort signal in response if the PCI slave has already claimed the address by asserting a device select signal. The bridge also includes logic that prevents the target-abort signal from propagating to the PCI bus whenever this logic receives both the address parity error signal and the device select signal. This allows the master to perform a master-abort and prevents the PCI slave on the bridge from performing a target- abort when there is an address parity error.

Abstract: This high-gain, wide-bandwidth antenna has several pairs of coplanar triangles, with a corner from each triangle at the centre and the two triangle sides opposite those corners being parallel to each other. Those pairs are in parallel planes and are aligned so that the parallel sides in each pair are also parallel to the parallel sides in the other pairs. The triangle dimensions and the distances between those pairs are progressively and proportionally smaller from the rear to the front of the antenna. Two feeder conductors are attached to the central corners of those pairs so that one conductor connects to one side of both triangles and the other conductor connects to the other side of both triangles. In addition, those connections are reversed between the adjacent pairs. The connection to the associated electronic equipment is usually at the front end of those feeder conductors.
