Patent CA-2286424-C (CA)
Inventor: PROZENIUK PERRY L
IPC: H04L12/70
Filed: 1999-10-18
Granted: 2007-08-07
Abstract: Constrained operation performance of exchanges (50) and switches (16, 216) of wireline communication systems (10) is mitigated and single entry point management of the system maintained through the provision of a distributed multi-service hub (MSH) sub-net (350) architecture in which individual MSHs (302-308) have hidden point codes (1001-1003). A signalling server (352) is able to translate an address of the MSH sub-net into a point code associated with an MSH entry point into the MSH sub- net, while dialled digit information pertaining to a service or party identifies a related MSH exit point from the MSH sub-net (350). A path can therefore be established, with the signalling server (352) further required to ensure that the hidden point code associated with the MSH exit point is translated back to the address of the MSH sub-net in onward routing of signalling messages to the dialled service or party. An intermediate element manager EM2 (312) isolates a management server OSS (54) from element managers (314-322) associated with the control of individual MSHs (302-310), with the intermediate EM2 (312) therefore providing a single address point to the OSS (54) while itself appearing as an OSS to the element managers (314-322) of individual MSHs (302-310). Signalling and management functions can therefore be consolidated at the intermediate EM2 (312) to increase efficiency and reduce overhead.

Abstract: A method and apparatus for collecting and transferring refuse to a transportation truck for hauling to its ultimate disposal site, such as a landfill. The apparatus comprises a refuse collection and transfer container movable between a first, lowered position and a second, raised position. When the container is in the raised position and the transportation truck is underneath, transfer of the collected refuse is accomplished by opening angled, retractable bottom doors on the container. The bottom doors allow for the regulation of the amount of refuse transferred to the truck, thus ensuring a full load within the truck while at the same time preventing spillage. The movement of the container and the doors may be powered by the hydraulic system of the truck and controlled by a control panel on the apparatus. The apparatus may be partially below ground level.

Title: Synchronization symbol structure using ofdm based transmission method
Inventor: BOHNKE RALF
IPC: H04J11/00
Filed: 1999-12-06
Granted: 2005-09-13
Abstract: The present invention proposes a method for generating synchronization bursts for OFDM transmission systems. The symbols of a predefined symbol sequence are mapped according to a predefined mapping scheme on subcarriers of the OFDM systems by a mapping unit (2), wherein the symbols of the predefined symbol sequence represent subcarriers of the OFDM system with nonzero amplitudes. A  synchronization burst is generated by a inverse fast Fourier transforming unit (3) transforming the subcarriers of the OFDM system mapped to said predefined symbol sequence. The mapping (2) of the symbols of the predefined symbol sequence is set such that the resulting time domain signal of the synchronization burst represents a periodic nature. According to the invention the predefined symbol sequence is set such that the envelope fluctuation of the time domain signal of the synchronization burst is minimized.   Therefore advantageous symbol sequences reducing said the envelope fluctuation of the time domain signal are proposed.

Title: Narrow profile opener capable of high speed operation
Inventor: FERGUSON LARRY PATRICK
IPC: A01B13/02
Filed: 2000-06-26
Granted: 2003-06-17
Abstract: An opener assembly includes a single opener disk rotatably supported from a drawbar and angled approximately five degrees from the forward direction to define a shadow area behind the trailing surface of the disk. A material placement boot and delivery tube are supported adjacent the trailing surface substantially entirely within the shadow of the disk and have profiles conforming to the furrow profile. The boot and the outlet portion of the tube also lie within the periphery of the disk for protection. The tube has an upper portion with a round cross section which changes to an elliptical cross section towards the outlet to remain within the shadow while retaining high throughput capabilities. First and second wheels are supported on opposite sides of the disk to urge soil downwardly behind the outlet of the delivery tube immediately after the material is deposited.  The immediate soil action caused by the closely spaced wheels pushes the material to the furrow bottom and prevents material bounce for more constant material depth. A short, lightweight wheel arm on the trailing side of the opener disk reduces assembly length and weight, and wheel bias towards the soil is primarily by spring action rather than weight for fast response to ground contours. The wheel on the leading side of the angled opener disk is supported behind the disk axis by an arm assembly which provides depth adjustment from the forward end of the drawbar. The wheels and the disk are angled generally in the same direction for handling trash.

Title: System and method for auditing in network applications
Inventor: WENIG ROBERT
IPC: H04L29/06
Filed: 1999-08-23
Granted: 2005-11-15
Abstract: A system and a method for auditing network applications captures data transmissions between a client (110) and a server (140) during a user session (130). An audit data capture filter captures each request from the client (110) and each response to each request by the server (140). An audit encryption module (1410) encrypts the captured requests and the captured responses using an encryption key and stores them in an audit memory (160). The audit encryption module (1410) additionally outputs parts of the encryption key to the client (110) and to the server (140). An audit decryption module (1520) captures the parts of the encryption key from the client (110) and from the server (140) and decrypts the encrypted requests and the encrypted responses. An audit analysis device can then use the decrypted requests and the decrypted responses to restore the user session (130) so that it is then possible to analyze what has happened during the user session (130). In addition, the audit analysis device can also verify that a particular event has occurred during the user session (130).
