Patent CA-2314749-C (CA)
Inventor: HATTORI YUICHI
IPC: F02C9/28
Filed: 2000-07-28
Granted: 2003-10-14
Abstract: In a control system for a gas turbine aeroengine having a control unit made up of an electronic control unit (ECU) which calculates a fuel flow rate command value based at least on the detected rotational speed of the turbine and the desired power output and a fuel control unit (FCU) including at least a fuel metering valve which meters fuel to be supplied to the engine based on the calculated fuel flow rate command value, the ECU is integrally connected to the FCU, thereby reducing the size and weight of the control units and hence, reducing the occurrence of resonance which would otherwise be likely to occur.  In the system, an alternator is integrally connected to the FCU and the rotational speed of the turbine is detected based on the wave form generated by the alternator.  Moreover, the ECU calculates the fuel flow rate command value such that the fuel flow rate to be supplied to the engine is brought to a prescribed value. This makes it unnecessary to provide the overspeed protector.

Title: Method and apparatus for covering a stent
Inventor: RICHTER JACOB
IPC: A61F2/90
Filed: 2001-01-15
Granted: 2009-03-24
Abstract: An expandable stent suitable for implantation in a lumen is covered with a biological material. In one embodiment, biological fibers are interwoven to form a stent covering. The fibers are disposed at an angle with respect to the longitudinal axis of the stent so that when the stent is expanded, the angle increases. In another embodiment, a strip of pericardium is helically wound around a supporting stent while the stent is in a compressed state. When the stent is expanded, the strip unwinds, but maintains full coverage of the stent. Interlocking edges may be formed on the strip of pericardium to maintain full coverage of the stent.

Filed: 1999-05-04
Granted: 2010-07-13
Abstract: Methods and apparatus are provided that implement digital signing and/or encryption for the electronic transmission, storage, and retrieval of authenticated documents and that enable the establishment of the identity of the originator of an electronic document and of the integrity of the information contained in such a document. Together these provide irrevocable proof of authenticity of the document.

A  Certification Authority provides tools for initializing and managing the cryptographic material required to sign and seal electronic documents. An Authentication Center provides "third party" verification that a document is executed and transmitted by the document's originator. The methods and apparatus eliminate the need for "hard copies" of original documents as well as hard copy storage. Retrieval of an authenticated document from the Authentication Center may be done by any number of authorized parties at any time by on-line capability.

Title: High-performance error-correcting codes with skew mapping
Inventor: HUNT ANDREW W
IPC: H03M13/00
Filed: 2001-05-25
Granted: 2008-03-11
Abstract: A method for generating new forward error correction codes, called skew codes, for the reliable transmission of data in noisy channels is disclosed. The method involves adding additional sets of parity equations across the third dimension of a cubic array of bits. The parity equations are applied to the cubic array such that the rectangular patterns of one square array do not match up with a rectangular pattern in another square array. By selecting skew mapping parameters of the parity equations from a set of quadratic residues of prime numbers according to specific design rules, the resulting codes are well suited to low-complexity high-speed iterative decoding, and have error correction performance and error detection capability, particularly for applications requiring high code rates. An improved decoding method for decoding skew codes and any code that is defined by a set of sum-to-identity parity equations initially decoded using an algorithm that provides confidence values on all the symbols at every symbol time is also disclosed. Generally, the improved decoding method will make hard decisions based upon the soft decisions passed from the failed iterative decoding system to provide a valid code word, through manipulation of the parity check matrix and reduction of its columns and rows.
