Patent CA-2294635-A1 (CA)
Title: Trampoline with enclosure
Inventor: GREINER JON H
IPC: A63B5/11
Filed: 1998-06-19
Abstract: A fence (30) surrounds a trampoline (20) and extends above the rebounding surface, reduc-ing the risk of injury. Shock absorption is aided in one embodiment by a support system of indepen-dent poles (86) linked at their tops by a flexible strap, or line (128). An impact anywhere on the fence causes the posts to flex inwardly, absorbing the force. Much of this impact injury is stored in system components, and is subsequently returned helping propel an errant jumper back onto the rebounding surface. One or more elastic cords can extend across the enclosed trampoline area to serve as a game accessory, either alone or in conjunction with other structures. Such an elastic cord can also support a tent-like structure over the rebounding surface. Numerous other embodi-ments, and various other trampoline game acces-sories (including electronic components, and wa-ter toys) are also detailed. Similar arrangements are suitable for use with above ground pools.

Patent CA-2302856-A1 (CA)
Title: Culvert system
Inventor: BOULET EDMOND E
IPC: E01F5/00
Filed: 2000-04-14
Abstract: A masonry culvert is formed from channel shaped components, including bottom components and inverted top components. The bottom components connect together end to end to form an upwardly open channel, while the top components connect end to end on top of the bottom components to complete the culvert. The reduced height culvert components are easier to handle and transport than full height components. They are more readily manufactured by casting them as inverted channels over a permanent mould core using movable end pieces and side panels. The cast component can be lifted directly off the core without the need to dismantle the core from the interior of a box-shaped culvert section.

Title: A method of dynamically adjusting the duration of a burst transmission in wireless communication systems
Inventor: RAMAKRISHNA SUDHIR
IPC: H04L12/56
Filed: 2000-03-29
Abstract: A method to adjust the burst transmission duration time, in a high speed digital wireless communication system, to provide sufficient time for the transmission of data when all the data is not available at the time of transmission. According to the method of the invention, after the burst transmission is begun, the burst is maintained active as additional data is detected within a known time period following the previous detected data packet and the detected data is appended to the active burst transmission. The invention further terminates the burst duration when no additional data is detected within the redefined time period following the previous detected data packet.

Title: Center clamp assembly for frame brace rail truck
Inventor: BULLOCK ROBERT L
IPC: B61F5/02
Filed: 2000-04-12
Abstract: A rail car truck has a pair of longitudinally spaced wheelsets and a pair of laterally spaced side frames which extend between and are supported by the wheelsets. A bolster extends between the side frames to support the rail car vehicle body. There is a brace which is connected to the side frames to control relative longitudinal movement therebetween. The brace includes a pair of struts which are diagonally connected to the side frames on opposite sides of the centerline thereof. The struts intersect generally centrally of the side frames and there is a clamp assembly for attaching the struts together. The clamp assembly includes a pair of clamp plates, each having a channel formed and adapted to receive a strut. Each clamp plate channel terminates at opposite ends of the clamp plate, with each clamp plate channel having a generally U-shaped opening. Each clamp plate is welded to a strut along the generally U-shaped openings thereof. There are fasteners which attach the facing surface of the clamp plates directly to each other. The clamp plates are welded, one to another. The clamp plate assembly inhibits relative movement between the struts in a generally horizontal plane.

Abstract: An echo canceller circuit (25) for use in an echo canceller system is set forth that provides sensitive non-linear echo path response detection (300). The echo canceller circuit (25) comprises a first digital filter (35) having non-adaptive tap coefficients to simulate an echo response occurring during a call. A second digital filter (30) having adaptive tap coefficients to simulate an echo response occurring during a call. The adaptive tap coefficients of the second digital filter are updated over the duration of the call. A coefficient transfer controller is disposed in the echo canceller circuit (25) to a transfer the adaptive tap coefficients of the second digital filter to replace the tap coefficients of the first digital filter when a set of one or more transfer conditions is met. A non-linear echo path response detector (300) is provided.  The non-linear echo path detector is responsive to one or more parameters of the first and second digital filters to detect a non-linear path condition. In accordance with one embodiment of the present invention, the non-linear echo path detector (300) is responsive to a transfer density value corresponding to a number of transfers executed by the coefficient transfer controller (65). In accordance with a further embodiment of the present invention, the non-linear echo path detector (300) is responsive to a coefficient time dispersion characteristic of the second digital filter for detecting a non-linear path condition.
