Patent number: 8148136Abstract: This invention relates to the protein, Mycobacterium paratuberculosis acylase (mpa) and the gene encoding mpa, which we have identified in the pathogen Mycobacterium paratuberculosis Mptb (also designated Mycobacterium avium subspecies paratuberculosis MAP), and to their use in the diagnosis of Mptb/MAP infections in animals and humans, as well as their use as components of vaccines for the prevention and treatment of diseases caused by Mptb/MAP. The importance of an intact uninterrupted mpa gene as a determinant of pathogenicity in Mptb/MAP is recognized and the invention also provides attenuated strains of normally pathogenic Mptb/MAP and other mycobacteria in which mpa has been inactivated, for use as vaccines.Type: GrantFiled: March 18, 1999Date of Patent: April 3, 2012Assignee: HAV Vaccines LimitedInventors: John Hermon-Taylor, Timothy John Bull

Patent number: 7303511Abstract: An exercise device includes two foot carriage assemblies. The foot carriage assemblies are operable to support a user's feet on a frame and to travel along a generally lateral path of motion. The foot carriages are operable to engage first and second torque tubes, which in turn participate in resisting the lateral movement of the foot carriages. A lateral striding motion on the exercise device may include a simulation of a motion associated with skating and/or skiing.Type: GrantFiled: February 1, 2006Date of Patent: December 4, 2007Inventor: John Bull

Patent number: 7293176Abstract: A method for enabling strong mutual authentication between two computers or devices in a communication system. A user attempting to gain access to a first computer transmits login information to the first computer. The first computer transmits a first message, including a first key encrypted by a second key, to the second computer. The first computer then transmits a second message to a third device. The second message includes the second key needed by the second computer to decrypt the first message. The third device uses the user's login information to obtain the user's private key, which the third device uses to obtain the second key. The third device transmits the second key in a third message to the second computer. The second computer then uses the second key to decrypt the first message and obtain the first key. Once the second computer obtains the first key, the second computer switches the role of the keys from the first message by encrypting the second key with the first key into a fourth message.Type: GrantFiled: May 20, 2004Date of Patent: November 6, 2007Assignee: Citrix Systems, Inc.Inventors: David Otway, John Bull

Patent number: 6799270Abstract: Described are a system and method for securely distributing session keys over a network to each node in a chain of computer system nodes. The chain of nodes recursively constructs and presents a nested request to the authentication server. The nested request includes a request from each of the nodes in the chain requiring a session key to communicate with a neighboring node. The authentication server recursively unravels the request and recursively prepares a response that includes a session key for each node that submitted a request. The response traverses the chain of nodes in the reverse order taken by the nested request to reach the authentication server. Each node receiving the response extracts the portion of the response directed to that node, and forwards the remainder of the response, if any, to the next node in the chain. Thus, with a single traversal of the chain of nodes each node receives at least one session key.Type: GrantFiled: September 24, 1999Date of Patent: September 28, 2004Assignee: Citrix Systems, Inc.Inventors: John A. Bull, David J. Otway
