Title: Method and apparatus for removing defects from digital images
Inventor: RICARD GARY ROSS
IPC: G06T1/00
Filed: 2001-03-02
Abstract: A relatively long, narrow defect in a digital image is repaired by identifyi ng an elongated area to be repaired, and by automatically calculating pixel color/shade valu es within the area to be repaired from pixel values in the vicinity of the perimeter of the elongated  area. Preferably, a user identifies an elongated rectangular area to be repaired on an interactive display. The computer automatically generates the pixel coordinates of a pair of parallel lines constituting the opposite long sides of the rectangle, and a set of line segments running between the long sides. The interior pixels of the rectangle are then filled by interpolating color values along each li ne segment. Since this method is not guaranteed to fill all pixels, the system optionally maintains  a map of pixels filled and not filled while performing this method, and after completion, performs an additional step of assigning to any unfilled pixels a value based on the average of all adjacen t pixels. For long, narrow defects, particularly those introduced by creasing, the automated digital image repair method herein described generally produces images without significant visually noticeable defects, and does so without undue effort on the part of the user.

Title: Extended distribution of adsl signals
Inventor: DODDS DAVID E
IPC: H04Q11/04
Filed: 2001-07-06
Abstract: A plurality of metallic telephone lines carrying both baseband POTS (plain old telephone service) and DSL (digital subscriber line) or ADSL  (asymmetric digital subscriber line) signals originate at customer premises and pass through a common field cabinet enroute to a telephone central office. Baseband POTS  signals flow in an undisturbed manner through the field cabinet and maintain the normal, highly reliable, communication between the subscriber premises and the central office telephone switch. At the field cabinet, DSL/ADSL signals are removed from the metallic telephone line and are then communicated between the field cabinet and the central office using fiber optic broadband transmission. Fiber optic transmission increases the allowed distance between the ADSL transceiver located at the customer location and the respective ADSL transceiver located in the telephone central office. In one arrangement at the optical fiber, DSL and ADSL signals are retained in their 2B1Q, DMT, QAM or CAP analog format and are simply frequency translated in the process of frequency division multiplex (FDM) transmission. In another arrangement the analog data is converted by an analog front end of an ADSL modem into digital signals which are then made into a serial signal for transmission on the fiber optic cable. The arrangements allow the provision of ADSL service to customers beyond the distance limit normally imposed by a completely metallic telephone line. It is understood that this arrangement is equally applicable to a variety of DSL (digital subscriber line) signals.

Title: Method of web turn-up in a web winder and apparatus therefor
Inventor: CASPAR ROMAN C
IPC: B65H19/26
Filed: 2001-07-26
Abstract: There is disclosed a method and apparatus for turning a web up onto a new empty core by severing the web from a full wound roll. The method utilizes at least one water jet cutter located immediately upstream and adjacent to a nip formed between a driving drum and an empty reel core. The method of cutting further utilizes twin water jet nozzle tail cutters located further upstream of the first water jet cutter. The twin cutters cut a strip into the web from the interior of the web which strip is directed downstream past the first water jet cutter. The first water jet cutter is limited to cut across the strip to form a leading tip that is wrapped around the new empty core. Once this wrapping onto the new empty core starts, the water jet tail cutters move to the outside edges of the web thereby widening the strip to the complete width of the web which is then wound onto the new empty core. By pressing the leading strip into the nip without the use of tape or a downstream air device, the amount of wrinkling of the first layers of paper on the new empty core is reduced thereby significantly reducing damage to and wastage of the paper wound onto the new empty core.

Patent CA-2356593-A1 (CA)
Inventor: WALKER EDWARD D
IPC: A63B69/36
Filed: 2001-08-10
Abstract: This invention is designed as a training guide to master the skill of putting using the Pendulum Stroke. Many golfers often have a difficult time mastering the concept of effective putting, because they fail to; .cndot. Keep the putter head square to the ball at impact. .cndot. Allow the left wrist to break down at impact (left wrist for right-handed golfer, right wrist for left handed golfer.) This problem causes the putter head to behave erratically. .cndot. Judge distance correctly. Many golfers take the club back too far and then decelerate in the downswing and then jab at the ball with almost no follow through. The Perfect Putt addresses all of these problems and teaches the golfer to master a smooth continuous stroke, while developing the feel for "The Perfect Putt". With the Pendulum Stroke, the hands and wrists remain still, while the action comes from the shoulders. Gently rock the arms back and forth to produce a smooth and controlled stroke, keeping the lower part of the body quiet.      To achieve the perfect putt; .cndot. Golfer places the putter between the Plexiglass rails directly and squarely behind the ball. .cndot. Golfer now addresses the ball, eyes directly over the ball, hands slightly ahead of ball. .cndot. Golfer now executes the pendulum stroke. Since the putter is being guided between the rails, the putter remains square at all times allowing the golfer to concentrate on smoothly accelerating the putter squarely through impact. The colour co-ordinated numbers on the adjusting rail will aid the golfer in determining the correct back swing which is equal to the follow through. With practice the golfer will develop the muscle memory, technique and knowledge to become an excellent putter.

Title: Adaptive frequency hopping strategy
Inventor: HUW BRYN JONES
IPC: H04B1/713
Filed: 2002-01-02
Abstract: A technique for controlling the frequency allocation in the hop sequence of a frequency hopping digital communications system is presented. The hop sequence is initially formed such that consecutive channels are likely to differ substantially in frequency. Therefore, channel substitution commands can be transmitted twice on consecutive hops without acknowledgement, inasmuch as the likelihood of a broadband noise source blocking consecutive channels is reduced. The number of channels identified as requiring substitution in the hop sequence is monitored, such that a hop sequence repair operation or communications link termination can be implemented if channel substitution data traffic becomes too great.
