Patent CA-2021361-A1 (CA)
IPC: H04L7/033
Filed: 1990-07-17
Abstract: ABSTRACT OF THE DISCLOSURE    An angular modulated signal is quadrature demodulated (37) into first and second signal vectors by a local carrier signal (36) having a frequency difference from a received carrier signal which is angular modulated by a modulating signal comprising symbols representative of binary one and zero at a symbol interval.  In the modulating signal, a particular symbol sequence comprises the symbols in a predetermined manner and results in the first signal vector.  A data symbol sequence comprises the symbols to represent data and results in the second signal vector. The first signal vector has inphase and quadrature phase amplitudes which are converted (41) to phase values substantially at the symbol interval.  An individual error is provided by comparing (44) a phase variation between two phase values (42 - 43) with a reference variation (45) determined by the predetermined manner.  Such individual errors are averaged (46) into a phase error (47) which is used in correcting (39) the second signal vector.  It is possible to compute the phase error by calculating the phase variation using a reference variation determined by the predetermined manner and the received carrier signal.

Patent CA-2028698-A1 (CA)
Inventor: HEUVEL JOHAN G F
IPC: A43B5/04
Filed: 1990-10-29
Abstract: Human anatomy provides angular ankle movement, known as dorsi flexion and plantar flexion, far in excess of that required for modern Alpine Skiing. The musculature of the lower leg is well adapted for controlling a foot sized lever. However, when the foot is extended to ski size dimensions, muscular strength is inadequate to afford the skier proper control over his position in relation to the ski, a position commonly referred to as forward-lean.      Conventional ski boots assist the skier maintaining the correct forward-lean position by using resilient stiffeners in combination with articulated areas or hinges, to effectively reduce the importance of the lower leg muscles as part of the total skier to ski equation and replace active muscle action by static positioning means.      The ski boot according to this invention uses the principles of leverage, reducing available angular ankle movement into a lesser and more controllable angular forward-lean movement, providing muscular adaptation, optimizing forward-lean control.

Abstract: DISPLAY DEVICE                         ABSTRACT   A display device having a front cartridge section against which objects can be stacked, one against the other, in a first line; first and second strips each wound about itself to define first and second coils with first and second axes; structure for connecting the strips to the front cartridge section so that the axes of the coils are transverse to the first line; and a rear cartridge section having first and second legs which are extendable at least partially through the first and second coils.  By moving the rear cartridge section away from the front cartridge section in the first line with the first and second legs extended into the first and second coils, the legs cause the first and second coils to unwind, whereby a force is developed on the first and second strips tending to draw the front and rear cartridge sections towards each other so that an article to be displayed can be resiliently captured in a display position between the front and rear cartridge sections.

Title: Digital switcher for routing signals
Inventor: ROE GRAHAM D
IPC: H04H20/78
Filed: 1990-11-26
Abstract: DIGITAL SWITCHER FOR ROUTING SIGNALS                    ABSTRACT OF THE DISCLOSURE       A digital switcher routes signals at rates up to or more than 300 MHz between switcher inputs and outputs.   The switcher includes an array of n rows and m columns of modules linking n groups of switcher inputs and m groups of switcher outputs. Each module consists of a primary switching unit for selectively coupling individual ones of its outputs to ones of its inputs and a number of individually-controllable, regenerative, two-input selector switches.    The primary and selector switches are controlled by a controller.   The selector switch outputs form the module outputs.   Each selector switch has an input connected to an associated output of the primary switching unit in the same module, and the other connected to an associated output of a module in the previous row of the array (apart from those in the first row).    The switcher outputs are derived from the outputs of the last row of modules.      To route a signal from a switcher input to a selected switcher output, the appropriate primary switching unit to which that switcher input is fed links its corresponding input to the selected one of its outputs.    The regenerative selector switches in that module and in modules in subsequent rows then cascade the signal from that module through the subsequent rows to the selected switcher output.

Title: Floating fluid-operated actuator
Inventor: JORNOD EUGENE R
IPC: F01L25/08
Filed: 1992-03-23
Abstract: The piston of a reciprocating hydraulic actuator carries a pump which is driven by an electric motor and which supplies oil from the low pressure chamber of a cylinder to the high pressure chamber thereof in order to advance the piston. An exhaust valve in the piston is normally held in a closed position by magnetic force created by energizing a coil and, when closed, enables pressurization of the high pressure chamber of the cylin-der. When a second coil is energized, the magnetic field of the first coil is negated and the valve is opened by a spring to permit oil to exhaust from the high pressure chamber to the low pressure chamber and permit a second spring to retract the piston. If both the pump motor and the second coil are de-energized, the first coil keeps the valve closed and causes the piston to remain in a commanded position. The actuator may be controlled by a floating single pole, double throw switch and its piston is automatically shifted to its fully retracted position by the second spring if electrical power to the actuator is lost.
