Title: Method and apparatus for singulating, debarking, scanning and automatically sawing and sorting logs into lengths
Inventor: STARR DONALD
IPC: B27L1/08
Filed: 2000-11-29
Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log.  This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths. The saws are adjusted in response to the computer solution and the log is positioned by a positioner according to a computer generated reference datum. This results in the log being positioned for cutting to the optimum random lengths. A command signal is sent from the computer to the log sorting system, which tracks the position of the random lengths and allows them to be sorted to the appropriate sort storage bin.

Abstract: An optical signaling header technique applicable to optical networks wherein packet routing information is embedded in the same channel or wavelength as the data payload (211) so that both the header (210) and data payload (211) propagate through network elements with the same path and the associated delays. The header (210) routing information has sufficiently different characteristics from the data payload (211) so that the signaling header can also be removed without affecting the data payload. The signal routing technique can overlaid onto the conventional network elements in a modular manner using two types of applique modules. The first type effects header encoding and decoding at the entry and exit points of the data payload into and out of the network; the second type effects header detection at each of the network elements.

Title: Efficient architectures for protection against network failures
Inventor: NAGARAJAN RAMESH
IPC: H04M3/00
Filed: 2001-04-11
Abstract: Traffic demands are routed between network elements so as to provide improved protection against network failures. A given tragic demand is routed from a first network element to a second network element, where the second network element is preferably either one of a set of dual-homed elements, or coupled to a dual-homed element, and may also be an element of a ring-type transport or a mesh-type transport. The second network element processes the traffic demand such that a copy of a signal associated with the demand is (i) retained at the second network element, while the signal is routed to at least one additional network element, or (ii) routed to at least one additional network element, while the signal is routed to at least one network element other than the additional network element. For example, in a multidrop connection implemented in accordance with the invention, a copy of the signal is "dropped" at the second network element and one or more additional network elements. In a multicast connection implemented in accordance with the invention, one or more copies of the signal are multicast from the second network element to multiple additional network elements.
