Patent CA-2180574-A1 (CA)
Title: Electronic speed governor
Inventor: DYKSTRA RICHARD A
IPC: F02D31/00
Filed: 1995-04-11
Abstract: The low cost speed governor for internal combustion engines may be completely powered by the ignition coil. The governor receives a periodic signal from the primary ignition winding (W1) that is indicative of the actual speed of the engine. A pulsed speed signal is generated that is functionally related to the periodic signal. The pulsed speed signal had a pulse width that is functionally related to the actual engine speed. A pulsed reference signal is generated by a timer circuit (U4), and has a pulse width that is functionally related to a predetermined reference speed. The pulsed speed signal is then compared with the pulse reference signal by a comparator circuit (G12), and a pulsed error signal is generated that has a pulse width which is functionally related to the difference between the speed signal pulse width and the reference signal pulse width. The speed of the device is then changed by a transistor bridge network as a function of the error signal.
Patent CA-2181659-A1 (CA)
Inventor: CUNNINGHAM CHARLES L
IPC: B60C25/138
Filed: 1996-07-19
Abstract: A quick release mechanism for the mount/dismount head of a rim holding tire changer, including a wedge plate that overlies the top of the horizontal bar and has an opening in registry with the opening in the sleeve through which the vertical bar passes. The opening in the wedge plate is shaped to mate with the cross-sectional profile of the vertical bar and is only slightly larger than the size of the bar. Thus, when the wedge plate is horizontal so that the axis of the opening is aligned with the axis of the opening of the sleeve, the vertical bar will move freely up and down in response to pressure on the vertical bar. The wedge plate has protrusions on its under side on one side of the opening and the protrusions rest on the upper face of the sleeve. A actuation handle is attached to the underside of the wedge plate and depends perpendicularly from it. The actuation handle is arcuate so that it mates with the outer perimeter of the sleeve and when held against the sleeve, the axis of the opening of the wedge plate will be aligned with the axis of the opening of the sleeve and the bar will be free to move within the sleeve. On the end of the wedge plate opposite the actuation handle is a spring biasing that end of the wedge arm downwardly. This action causes the angle of the axis of the opening through the wedge plate to be askew to the axis of the opening of the sleeve, thereby reducing the length of the opening by the angle of the thickness of the plate, causing the plate to wedge against the vertical bar and bind it against movement vertically within the sleeve. By this structure, the vertical bar will be held in place unless the operator grips the actuation handle and forces it against the sleeve against the pressure of the spring, causing the openings to be aligned and releasing the vertical bar for movement within the opening of the sleeve.
Patent CA-2185134-A1 (CA)
Title: Apparatus for synthesizing speech by varying pitch
Inventor: LOWRY ANDREW
IPC: G10L13/04
Filed: 1995-03-17
Abstract: The pitch of synthesised speech signals is varied by separating the speech signals into a spectral component and an excitation component.  The latter is multiplied by a series of overlapping window functions synchronous, in the case of voiced speech, with pitch timing mark information corresponding at least approximately to instants of vocal excitation, to separate it into windowed speech segments which are added together again after the application of a controllable time-shift. The spectral and excitation components are then recombined. The multiplication employs at least two windows per pitch period, each having a duration of less than one pitch period. Alternatively each window has a duration of less than twice the pitch period between timing marks and is asymmetric about the timing mark.

Title: Method for asymmetrically attenuating signals in a transmission system
Inventor: MORGAN ISAAC E
IPC: H04N7/173
Filed: 1997-05-29
Abstract: Ingress noise in a hybrid fiber-coax transmission system (10) may be reduced by employing asymmetric taps (30 1'-30 8',) between a pair of line extenders (28-28) for attenuating downstream and upstream information by different weights. The downstream weights of the taps are selected to achieve a substantial constant power level at each tap for individual subscribers (14-14). The upstream attenuation of each tap is selected to allow for a nearly constant level of subscriber-generated information to be received at the line extender while the subscriber generated upstream information is supplied to the taps at a constant value that is maximized to reduce the effect of ingress noise.
