Patent CA-2337352-A1 (CA)
Title: Method and apparatus for signaling path restoration information in a mesh network
Inventor: HARSHAVARDHANA PARAMASIVIAH
IPC: H04L69/40
Filed: 2001-02-16
Abstract: A method and apparatus are disclosed for monitoring and signaling a path restoration using pre-computed restoration paths following a detected fault on a primary service path in a communications network. A fault occurring inside the restorable portion of a network in heterogeneous or multiple network environments can be distinguished from faults occurring outside the restorable network in accordance with the ANSI Tandem Connection Maintenance standard, T1.105.05-1994. Path restoration is activated only when a fault causing path failure occurs inside the restorable portion of the network. Each conforming node in the restorable portion of the network has the necessary monitoring, signaling and cross-connect functionality and databases to participate actively in real time restoration. Additional non-conforming network elements can be positioned between the restoration nodes without preventing path restoration. With the signaling architecture of the present invention, when an end-node detects a path failure caused by an in-network fault, it formulates a signaling message for restoring the failed path. The restoration signaling message is thereafter relayed from one node to another in the overhead or payload of signaling paths that occupy the same bandwidth that is subsequently used by the restoration path. Once a signaling message is transmitted to an adjacent node in the overhead or payload of a particular signaling path, the node that transmitted the message makes a cross-connect that replaces the signaling path with a segment of the restoration path whose set-up was requested in the transmitted signaling message.

Title: Transmitter, receiver and method in a telecommunication system for generating pn sequences for a plurality of user channels
Inventor: LEUSCHNER HELMUT
IPC: H04L7/04
Filed: 1999-08-24
Abstract: In a telecommunication system where a plurality of user channels are processed in a time-slotted manner, a transmitter and receiver can perform bit error rate measurements for a plurality of user channels by only using one PN-generator (T-PN) and one state memory (ISM). A read/write means (R/W) is provided for reading to and writing from to the state memory (ISM). Whenever a timing means (TM) detects the beginning of a new time-slot, the read/write means (R/W) reads out a last-stored phase state from the state memory (ISM).  When detecting the end of the respective time-slot, the phase state then present in the PN-generator (T-PN) is stored into the state memory (ISM) to be used for re-initialization of the PN-generator (T-PN) for the same time-slot in a succeeding frame. Thus, one PN-generator (T-PN) is enough for generating PN-sequences for a great number of user channels.

IPC: F26B17/00
Filed: 2001-05-11
Abstract: Conditioning apparatus for handling particulate material comprises a central frame and a plurality of spaced, annular troughs mounted to the central frame to support the particulate material. The troughs are arranged in a stacked configuration having successive pairs of upper and lower troughs with an uppermost trough for receiving the particulate material and a lowermost trough for discharging particulate material. Hydraulic cylinders or other suitable means are used to impart vibratory movement to the plurality of troughs to fluidize and advance the particulate material in a first direction on each of the plurality of troughs. A passage is formed through each trough for particulate material to fall from the upper trough of a pair to the lower trough.      The passage of the upper trough is non-aligned in a vertical plane with the passage of the lower trough such that particulate material falling from the upper trough is received on the lower trough to travel in the first direction over the distance of the lower trough before reaching the passage of the lower trough. A mixing surface is provided in each passage to promote tumbling and mixing of the particulate material which tends to ensure that all surfaces of the particulate material are exposed and available for the conditioning process. The conditioning apparatus finds particular application in drying of particulate material by passing drying gas through the fluidized material, or in filtering or scrubbing of gas by passing the gas through fluidized particulate material.

Abstract: The present invention concerns a method that is timesaving, more economical and facilitates the handling and processing of short solid wood planks. Tongue-and-groove joints are machined on the short sides of the short green planks enabling their releasable tight assembly in rows for the seasoning process in the kiln dryer. This temporary attachment between adjacent planks prevents exposition of the short sides to the drying air thus avoiding the usual end grain checking on the latter during kiln drying, and eliminates the need of performing any subsequent machining and trimming steps after the expensive kiln drying step. This process then also improves the saving opportunities by increasing the volume of wood drying capacity and by increasing the production of reusable green wood shavings as opposed to unusable wood shavings following the kiln drying operation.
