Patent CA-2125443-C (CA)
Inventor: RIEDER KLAUS-HARTWIG
IPC: H03L7/18
Filed: 1994-06-08
Granted: 1999-04-06
Abstract: The circuit arrangement of the invention presents an oscillator, whose frequency can be linearly varied within a wide control range, without affecting the oscillator's stability.  The frequency of a fixed frequency generator (1) is divided to the desired frequency by a frequency divider (2), whose divider ratio can be varied in very small steps, and the resulting jitter is filtered out by a very simple phase control circuit (3).  Improved short-term stability and holdover performance are also achieved.  The oscillator can be universally used as clock generator in all digital circuit arrangements.

Filed: 1994-12-22
Granted: 1998-07-07
Abstract: A method of, and an apparatus for, identifying a system which allows a filter coefficient to be updated accurately even if noise is mixed.  The apparatus for identifying a system includes an adaptive filter for processing a reference input signal to produce an output signal, a subtractor for subtracting the output signal of the adaptive filter from an observed signal, a power-estimating circuit for estimating the power of the reference input signal, and a step-size determining circuit for determining a step size based on the estimated power of the reference input signal.  The step-size determining circuit generates a step size according to a function of the power of the reference input signal, which monotonously increases if the power of the reference input signal is smaller than a threshold and monotonously decreases if the power of the reference input signal is greater than the threshold.

Title: Selective cardiac activity analysis atrial fibrillation detection system and method and atrial defibrillator utilizing same
Inventor: WHITE HARLEY
IPC: A61N1/39
Filed: 1995-03-27
Granted: 2001-04-17
Abstract: An atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion.          The defibrillator includes an electrode pair and a sense amplifier associated with the atria of the heart for sensing electrical activity of the heart during a plurality of cardiac cycles to provide a cardiac signal.  A detector is responsive to the cardiac signal for detecting cardiac events.  During each cardiac cycle of the plurality of cardiac cycles, a time for counting is established wherein each time for counting has a total duration less than the duration of its corresponding cardiac cycle.  A counter counts the cardiac events detected by the detector during the time for counting of the plurality of cardiac cycles to provide a cardiac event count.   A comparator compares the cardiac event count to a predetermined cardiac event count.  If the cardiac event count is greater than the predetermined cardiac event count, the atria are deemed to be in fibrillation and a cardiovertor applies cardioverting electrical energy to the atria to cardiovert the detected atrial fibrillation.

Patent CA-2163303-C (CA)
Inventor: SARINGER JOHN H
IPC: A61H1/02
Filed: 1995-11-20
Granted: 1999-08-17
Abstract: The present invention provides continuous passive motion (CPM) devices for joints. An ankle CPM device includes a lower leg support attached at its lower end to a semi-circular track. An actuator slides along the track and can be locked in any desired position on the track. A shaft is pivotally connected at one end thereof to the actuator and a shoe is attached at the other end thereof. When the actuator is positioned at the bottom of the track the ankle joint of the patient undergoes inversion/eversion motion. When the motor housing is rotated 90° and positioned near the top of the track plantar/dorsi flexion movement is obtained. A combination of both types of joint movement are obtained for the actuator in intermediate positions. A wrist CPM device includes a brace for the forearm attached to a semi-circular track on which an actuator is mounted. A hand grip is mounted on a semi-circular bracket and a shaft extends between the actuator and a coupling slidably mounted on the semi-circular bracket. With the actuator positioned below the forearm, when the actuator pivots the shaft the wrist joint undergoes ulnar/radial deviation movement and when the motor is rotated 90° and positioned at the side of the arm extension/flexion movement of the wrist joint is obtained. Positioning the actuator in intermediate positions produces wrist movement which is a combination of extension/flexion and ulnar/radial deviation of the wrist joint.

Granted: 1999-06-15
Abstract: A color-changing, position-reversible hourglass assembly having two transparent bulbs one above the other and a storage compartment adjacent each bulb, the bulbs and compartments being joined together by a neck.  Intercoupling the bulbs and the compartments is a crossover network which passes through the neck to couple each bulb to the compartment adjacent the other bulb.  In operation, when one bulb and its adjacent compartment are in an up position and are respectively loaded with sand of different color, then sand of one color appears to trickle from the up bulb into the compartment in the down position while sand of another color appears to trickle from the up compartment into the down bulb.  The resultant apparent flow of sand from a higher to a lower level creates the illusion that sand flowing out of the up bulb is undergoing a color transformation as it flows into the down bulb.

Granted: 1999-08-10
Abstract: In a method and apparatus for decompressing a digital video signal representative of an input sequence of digital video frames, a digital video signal is provided to a video decompressor having a target frame decompression rate which is initially set at the maximum possible frame rate.  The output of the video decompressor is monitored to determine whether the video decompressor is timely generating the output sequence of digital video frames.  If the video decompressor is not timely generating the output sequence of digital video frames, then the video decompressor output is adjusted by omitting from the output sequence at least one frame from the input sequence.  A frames missed value is generated in response to each group of one or more omitted frames, and deviations in the frames missed value are monitored. The target decompression rate of the video decompressor is selectively adjusted downward in response to deviations in the frames missed value.
