Patent CA-2096352-A1 (CA)
Title: Digital data converter
Inventor: JACOBS GORDON M
IPC: H03M7/00
Filed: 1991-10-22
Abstract: A decoder for recovering an analog signal from its digital representation produced by an encoder employing adaptive-delta-modulation first decodes audio bit-stream (17) in the digital domain with digital delta demodulation (15), to a pulse-code-modulation (PCM) format digital signal. Post-processing (35), complementary to encoder processing is performed digitally on the PCM signal. The output from post-processor (35) is up-sampled, and using delta modulation, a noise shaped single-bit highly oversampled output is produced by converter (14). Applying the single-bit output to lowpass filter (11) re-constructs the decoded analog signal, which is audio output (12). By fully exploiting digital signal processing techniques, the decoder can be manufactured at low cost and exceed the performance of existing analog implementations.

Title: Method and Apparatus for Event Processing in Biological Applications
Inventor: SWANSON DAVID K
IPC: A61N1/39
Filed: 1993-05-18
Abstract: A method and apparatus for processing biological signals on an event basis. An event low pass filter (LPF) is provided which passes variations in event features below an event cut-off value, which is analogous to the time-based cutoff frequency. An event high pass filter (HPF) is provided which passes variations in event features that are above an event-rate cutoff. An event variability detector is provided which determines the variation of a discrete variable from values at prior events. An event discriminator is provided for filtering out contributions of unrelated events that are superimposed on a discrete periodic measurement of interest. In all of these techniques, sampling of a biological signal is performed in coincidence with a biological event which does not occur at a constant frequency. In accordance with another aspect, an algorithm is provided using event-based techniques for discriminating abnormal rhythms from normal sinus rhythm on the basis of atrial rate, ventricular rate, and A-V intervals. An interval conditioning stage is provided for processing intervals of atrial beats, ventricular beats, and atrial to ventricular beats and classifying intervals for each according to an adaptive triple-bin technique. The three bins are defined as "current", "fast" and "slow" and each comprises memory space for storing the count of intervals stored into the particular bin and the average value of those intervals.

Abstract: A method is disclosed for producing a polyurea-cellulose composite material from substantially delignified cellulosic material and an isocyanate resin. The isocyanate resin comprises a polyisocyanate, preferably PMDI, and a miscible organic solvent, preferably one such as propylene carbonate having a high boiling point and low flammability and toxicity. The composite surprisingly exhibits values of physical parameters that are at least as good as, and sometimes far superior to, corresponding parameters of similar composites made using neat (undiluted) polyisocyanate. Single- and multiple-ply composites can be made, employing only a single curing step.

Abstract: The manually-operated balloon stuffing device has a minimum number of parts and is inexpensive to manufacture. The device includes a manual pump consist-ing of inner and outer cylindrical tubes, and a check valve in each tube that permits the passage of air in only a single direction within its respective tube. In a first embodiment, a balloon stuffing item is placed in an end of the inner tube, and the open balloon end is stretched over that tube end. The outer tube is then reciprocated along the longitudinal axis of the inner tube to pump up the balloon. The outer tube is then removed and a push rod pushes the sliding check valve, which in turn pushes the stuffing item into the inflated balloon. In an alternate embodiment, a large hollow adapter tube is placed on the end of the inner tube, and the open end of the balloon is stretched over the open end of the adapter tube. After the balloon is inflated, a push rod pushes the sliding check valve, which in turn pushes an extension rod, the latter moving the stuffing item into the balloon. In yet a third embodiment, the need for a push rod and a slidable check valve is elimi-nated by using a connector between the tube in which the item is placed on the upper end of the inner tube. Once the balloon is inflated as before, the inner tube is pushed through the third hollow tube, thereby pushing the item into the balloon.

Abstract: A clamp circuit for use in a clock circuit having a phase-lock loop, the phase-lock loop including a phase detector, a loop filter, and a voltage-controlled oscillator, the clamping circuit connected between the loop filter and the voltage-controlled oscillator.  The clamping circuit selectively provides, under the control of a clamping signal either a path for the loop through the clamping circuit or clamping the input of the voltage-controlled oscillator to varying potential. The varying potential is provided by a resistor capacitor network. When the loop is closed the capacitor is charged to an average of the loop control voltage for the oscillator.  In response to the clamping signal the capacitor is connected to ground, thereby providing an RC time constant varying potential which allows the oscillator to be clamped to a fixed voltage in a slew-rate controlled manner.
