Patent number: 7340396Abstract: Speech feature vectors (10) are provided and utilized to develop a corresponding estimated speaker dependent speech feature space model (20) (in one embodiment, it is not necessary that this model (20) have defined correlations with the verbal content of the represented speech itself). A model alignment unit (21) then contrasts this model (20) against the contents of a speaker independent speech feature space model (24) to provide alignment indices to a transformation estimation unit (23). In one embodiment, these alignment indices are based, as least in part, upon a measure of the differences between likelihoods of occurrence for the elements that comprise the constituency of these models. The transformation estimation unit (23) utilizes these alignment indices to provide transformation parameters to a model transformation unit (25) that uses such parameters to transform a speaker independent speech recognition model set (26) and yield a resultant speaker adapted speech recognition model set (27).Type: GrantFiled: February 18, 2003Date of Patent: March 4, 2008Assignee: Motorola, Inc.Inventors: Mark Thomson, Julien Epps, Trym Holter

Publication number: 20070094847Abstract: A hinge for a boom associated with a spacecraft antenna or other payload. The boom hinge includes two hinge bodies and at least three links, where one of the links is a drive link. The resulting hinge is an N+4 bar linkage. An actuator rotates the drive link so that the other links wrap around it, and the next link in the series of links acts as a drive link as the links get wrapped around the primary drive link. At the end of the deployment, the hinge precisely emulates the classic four-bar over-center latch behavior. This allows any hinge-offset distance between the hinge bodies when stowed in a larger hinge rotation angle without structural compromises.Type: ApplicationFiled: November 3, 2005Publication date: May 3, 2007Applicant: Northrop Grumman CorporationInventor: Mark Thomson

Patent number: 6800282Abstract: A wound dressing which comprises a carrier layer having a non-adherent to cell layer on a wound facing surface thereof. The non-adherent layer has bonded thereto a biodegradable cell anchoring layer which anchors mammalian cells. In use, the degradable layer breaks down releasing the cells into the wound site which are discouraged from reattaching to the dressing by the non-adherent layer. Thus the dressing can switch from a cell binding state to a state in which the binding of cells is discouraged. Systems, methods of treatment and methods of manufacturing the dressing are also disclosed.Type: GrantFiled: February 11, 2000Date of Patent: October 5, 2004Assignee: Smith & Nephew, PlcInventors: Brian Mark Thomson, Saad Abdul Majeed Ali, Nicholas Medcalf, John Maltman, Sharon Dawn Maltman
