Title: Coding method and apparatus
Inventor: FARRELL WADE NICHOLAS
IPC: H04L1/00
Filed: 1997-12-24
Granted: 2006-01-31
Abstract: A parallel concatenated coder (20) outputs a sequence of data sets in which earlier data sets contain data bits (d) and non-interleaved parity bits (p) without interleaved parity bits (q), while later data sets include the interleaved parity bits (q). Each data set is modulated as one symbol. The output format partially overcomes the delay incurred by interleaving the parity bits (q), with a substantially even distribution of data and parity bits in the sequence of data sets. The delay may be reduced further by interleaving with an index constraint.

Patent CA-2328745-C (CA)
Inventor: BAIER BRUCE A
IPC: E05F11/34
Filed: 2000-12-19
Granted: 2005-10-18
Abstract: The operator assembly for a casement window includes a folding crank handle and cover assembly that are located on the exterior surface of a trim piece on the sill of the window frame. The crank handle is attached to the drive shaft of the operator of the assembly in such a way that the handle may be folded down into a low-profile position in which the knob of the handle projects into a receiving pocket in the cover.  An integral flap on the handle extending beyond the knob covers the pocket when the knob is received therein so as to fully conceal both the knob and the pocket and to present a smooth exterior in which surfaces of the handle and cover blend together to eliminate interference with window treatments and persons in the immediately vicinity.  Internal detent projections within the pocket yieldably retain the knob so as to provide for snap fit reception of the folded handle into its home position. Finger depressions in sidewalls of the cover on opposite sides of the pocket facilitate gripping of the edges of the handle for unfolding, even though the handle presents a relatively thin cross sectional configuration in the vicinity of the cover flap and pocket. An alternative embodiment discloses an egress operator assembly in which the single link arm that swings the sash between opened and closed positions has a hump adjacent its inner end that clears the worm gear of the operator assembly when the arm is in its fully closed position, thus allowing the arm to cross over the worm gear and lie along the sill in a compacted condition when the sash is closed.

Patent CA-2331975-C (CA)
Inventor: BAUER ERIC JONATHAN
IPC: H04M7/00
Filed: 2001-01-19
Granted: 2006-06-06
Abstract: A method and apparatus are disclosed for congestion management in a multi-branch Internet Protocol (IP)-based private branch exchange (PBX) switch. The multi-branch IP-based PBX switch is interconnected through (i) a packet network referred to as the primary network, such as a wide area network (WAN), and (ii) an alternate network, such as the public switched telephone network (PSTN),. Packet phone adapters (PPAs) associated with each packet telephone unit monitor packet telephone calls and report delay information to communication servers. The communication server can reroute the packet telephony calls through the secondary network upon detection of congestion in the underlying primary network, thereby preserving voice quality. The packet phone adapter (PPA) will discard records collected from calls whose duration is below a minimum value, to ensure reliable congestion information. Each communication server records reported voice quality of service information in a congestion control database. An overload control process processes each call set up request and determines if the requested path is congested. If a requested path is congested, then the overload control process may forward the call using the secondary network.

Granted: 2005-05-17
Abstract: A peeler block is formed previously on its opposite end faces with markings the centers of which define an optimum axis about which the block should be rotated for achieving maximum yield in peeling veneer from the block in a rotary veneer lathe. An apparatus is disclosed herein which is designed to detecting such markings at two different detecting stations and finally positioning the block such that its optimum axis is set parallel to the axes of spindles of a rotary veneer lathe is disclosed. At the first station, the markings are detected by a first pair of image sensors such as CCD cameras having lenses with a short focal length hence wide-angle viewing capability. After the detection, the block P is transferred to the second detecting station under the control by a computer control in such a way that the detected respective markings may reach predetermined positions at the second detecting station, where the markings are detected by a second pair of image sensors having lenses with a long focal length for high resolution capability so that the markings are detected with increased accuracy. The block P is further transferred to a third station under the control of the computer control so that it can be positioned at the third station with the optimum axis of the block P expending substantially in parallel to the axes of the lathe spindles.

Abstract: A handoff method in a CDMA communication system using Walsh codes and quasi-orthogonal codes. To implement a handoff, a new base station to which a call is switched notifies a serving base station of an available quasi-orthogonal code, if the new base station has no available Walsh codes. The serving base station transmits a handoff direction message to a mobile station and the mobile station communicates with the new base station using the quasi-orthogonal code included in the handoff direction message.

Granted: 2007-10-16
Abstract: A pontoon composed of a series of hollow pontoon elements which when mounted on a pair of guide rails becomes an integral assembly forming a pontoon. The elements, with the exception of the bow and the stern elements, are identical, with the stern and bow elements having a curved water engaging surface to decrease the resistance to passage through the water. The pontoon elements are mounted between a pair of metallic channels where they may be suitably fastened during use. A screw jack or cable may be used to apply a compressive force to the various pontoon elements to form an integral pontoon assembly. The mounting system used securing for the various pontoon elements to the channel members permits easy removal of a damaged element and swift installation of a suitable replacement element without having to remove the complete pontoon assembly from the craft on which the pontoon is mounted. The pontoon system may be advantageously used for watercraft (houseboats, floating and moving barges), bridges and float assemblies for aircraft.

Abstract: Fine particles of dust and other pollutants in gas streams entering a duct (10) are agglomerated to form larger particles which are more easily filtered in downstream processing. Particles in successive portions of the gas stream are charged by an AC ionizer (14) with opposite polarity, and the gas stream is introduced into an Evase portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, aided by vibrators (13), leading to agglomeration of oppositely-charged particles.
