Patent CA-2130217-A1 (CA)
Inventor: WILLIAMS ROSS E
IPC: G01S15/87
Filed: 1994-08-09
Abstract: Apparatus and methods for improving signal detection and tracking in underwater acoustic devices receiving a set of acoustic pulses propagated in response to repetitive synchronizing events. Each of the set of pulses is correlated with a replica of each pulse in a receiver in the underwater devices during an associated time window. The correlated output of the receiver is compared to an adjustable threshold characteristic in a detector for selection of the actual pulse according to predetermined criteria for each of the set of pulses. An actual time of reception relative to the synchronizing event is assigned to the selected pulse. Previous actual times of reception are used to estimate the expected time of reception of the associated pulse relative to the next synchronizing event. The estimate is used to adjust the associated time window to encompass the expected time of reception. Previous actual times of reception are compared to corresponding estimated times of reception to develop a measure of the quality of the estimates. The shape of the threshold characteristic and the width of the associated time window are adjusted as a function of the measure of the quality. A preferred threshold characteristic has a parabolic shape with its vertex defining a minimum threshold level at the expected time of reception. High quality measures lower the minimum threshold and narrow the parabola and the time window; low quality measures raise the minimum threshold level and broaden the parabola and the time window. Adaptive signal tracking is thereby provided.

Title: Bottle cap opener
Inventor: DUGUAY PAUL
IPC: B67B7/16
Filed: 1994-08-19
Abstract: A bottle cap opener for bottle caps which are removable by rotation and have a depending, side wall with n circumferentially evenly distributed ridges and intermediate valleys, includes a rigid support member for supporting x upstanding teeth which are affixed to the support and equidistantly distributed in a circle about the center thereof. The integer x is larger than 2, smaller than n and wholly divisible into n, and is preferably 3. Each one of the teeth has a radially inwardly protruding sharp edge which is adapted to engage one of the valleys of the cap to provide leverage for rotating the bottle cap by rotation of the support. The opener is of simplified construction, fits reliably on twist-off or screw-off bottle caps and permits removal of the caps without slipping or the need for excessive force.

Title: Transfer mechanism for web winding device
Inventor: KREMAR DJURO
IPC: B65H19/22
Filed: 1995-02-24
Abstract: There is disclosed a web winding device for winding a substantially continuous web onto a rotating reel bar. The winding device includes a driving drum having an axis about which the drum is rotated. The driving drum maintains a nip driving engagement with the reel bar to rotate the reel bar and transfer the web passing over a surface of the driving drum onto the reel bar. The winding device further includes a transfer mechanism for moving the reel bar from a primary winding position where the web is initially wound onto the reel bar to a secondary winding position while maintaining the reel bar in nip driving engagement with the driving drum. The transfer mechanism includes rotating transfer arms mounted to rotate about an axis aligned to the axis of the driving drum. The rotating transfer arms support movable supporting jaws adapted to secure the reel bar and support the reel bar as it moves from the primary winding position to the secondary winding position. The transfer mechanism further includes actuator apparatus comprising movable linkage and rotator apparatus. The movable linkage interconnects the rotator apparatus to the rotating transfer arms. The rotator apparatus rotates a predetermined angular amount at a predetermined rotational velocity to cause the linkage to move and control the rotation of the rotating transfer arm about the axis of the driving drum. By providing linkage and a rotating machine of limited rotation, the present invention eliminates the use of a gear wheel rack and pinion and the associated problems that occur as the teeth in the gears wear out.

Title: Digital high-pass filter having baseline restoration means
Inventor: BROOKS JAMES R
IPC: H03H17/02
Filed: 1995-05-16
Abstract: DIGITAL HIGH-PASS FILTER HAVING    BASELINE RESTORATION MEANS   A digital high-pass filter derived from a digital low-pass filter of conventional design. The digital low-pass filter periodically calculates respective low-pass filter output values. Corresponding high-pass filter output values are then calculated by subtracting the low-pass filter output values from input samples provided by digitizing an input signal. The high-pass filter output values are then used to generate samples which are applied to a digital-to-analog converter for outputting a high-pass filtered replica of the input signal. The digital high-pass filter compensates for sudden. relatively large changes in the input signal by comparing the low-pass filter output value to the input sample and, in the event that there is a large discrepancy therebetween, setting the low-pass filter output value to the input sample before calculating the high-pass filter output value.

Title: Golf ball dimple configuration method and product
Inventor: STIEFEL JOSEPH F
IPC: A63B45/00
Filed: 1996-03-29
Abstract: A dimple configuration for the surface of a golf ball is provided by selecting a fixed number of dimples, placing said dimples on a computer model of the ball in random, helter-skelter locations on one selected section without regard to the other dimples present, and identifying each dimple and the adjacent dimples which overlap it.  For each dimple so identified, the aggregate component of overlap in the longitudinal and latitudinal directions is computed, the center of each dimple is relocated so as to minimize over-lap, and the steps of identifying, computing, and relocating are repeated for each dimple until the aggregate overlap is reduced to a predetermined amount.  The resultant ball provides a random dimple configuration which has no repeat-ing patterns within the sections.
