Title: Diagnostics and therapy of epstein-barr virus in autoimmune disorders
Inventor: HARLEY JOHN B
IPC: A61P11/02
Filed: 1998-01-13
Abstract: Data consistent with autoimmune disease being caused by Epstein-Barr virus are shown. Based on this evidence, an effective vaccine would prevent the autoimmune disease in those vaccinated, modified or administered so that the vaccine is not itself capable of inducing autoimmune disease. In the case of anti-Sm, structures to be avoided in Epstein-Barr virus-derived vaccine have been identified. Differences have been identified in the immune responses to Epstein-Barr infection between individuals who develop a specific autoimmune disease and those who do not. These differences are used to distinguish those who are at greater risk for developing specific autoimmune diseases from those who are at lesser risk. Assuming Epstein-Barr virus causes autoimmune disease and that Epstein-Barr virus remains latent in the patient for life, reactivation of the virus from the latent state is important in generating or maintaining the autoimmune response that culminates in autoimmune disease. Cells infected with latent virus may also encourage autoimmunity. Based on the understanding that reactivation or latency are important to produce or sustain autoimmunity, then therapies directed against Epstein-Barr virus will also be effective therapies for the autoimmune manifestations of disease for which Epstein-Barr virus is responsible.

Title: Vehicle wheel alignment adjustment method
Inventor: HATTORI YOZO
IPC: G01M17/06
Filed: 1999-08-19
Abstract: A wheel angle of a wheel is adjusted in accordance with the characteristics of tire of the wheel such that a steering characteristics of the vehicle is substantially neutral steer. The wheel angle of a reference wheel of the vehicle (for example, a rear wheel) is adjusted. Next, the reference wheel and a non-reference wheel (for example, a front wheel) are rotated on the tire driving surface of an endless track on which are formed a plurality of plate-like protrusions of a predetermined height. The longitudinal and lateral forces generated in the tire are then measured. On the basis of the wave forms of the rate of change measured in the longitudinal force, a predetermined period is determined from the time when the tire is deformed as the wheel passes over the upward step of the protrusion until the tire is deformed as the wheel passes over the downward step of the protrusion, and data of the lateral force measured within the predetermined period is extracted. The wave forms of the lateral forces of both wheels indicated by the extracted data are superposed, and the direction in which the toe angle of the non-reference wheel should be adjusted is calculated on the difference in the wave forms.

IPC: G05G9/047
Filed: 1998-02-18
Abstract: A force feedback interface (34) including a haptic accelerator (60) that relieves the computational burden associated with force feedback generation from a force feedback processor (54). The force feedback processor (54) is preferably a device microprocessor (54) included in the interface device and separate from a controlling host computer (32) for determining forces to be output. The haptic accelerator (60) quickly determines velocity and/or acceleration information describing motion of a user manipulatable object (66) from raw position data received from sensors (62) of the interface device and representing the position of the user object (66). The velocity and/or acceleration data is used by the force feedback processor (54) in the determination of forces to be output on the user object (66). The haptic accelerator (60) can in some embodiments also quickly and reliably determine condition forces which depend on the motion of the user object (66), thus relieving additional computation burden from the force feedback processor (54) and permitting the force feedback processor (54) to focus on determining other types of forces and overseeing the operation of the force feedback interface device (34).

Title: Method and end station with improved user response time in a mobile network
Inventor: MAINI VIJI
IPC: H04L12/56
Filed: 1998-02-10
Abstract: A method and apparatus of improving user response time during cellular hand-offs and radio frequency changes in a Transmission Control Protocol/Internet Protocol (TCP/IP) mobile environment. In the mobile environment there is at least a mobile end station (20), a mobile data base station (22), a mobile data intermediate system (MDIS) (30) and a fixed end station (40). The MDIS  (30) keeps track of the mobile end station (20) as it roams through the mobile environment. As a result, the MDIS (30) can distinguish between delays due to network congestion and delays due to cellular hand-offs. Further, the mobile data base station (22) informs the MDIS (30) of any changes in the radio frequency signal, thus allowing the MDIS (30) to also recognize delays due to changes in the radio frequency signal. With the knowledge of being able to identify the cause of the delays, the MDIS (30) is able to initiate or suppress a congestion control and recovery process.

Patent CA-2287994-A1 (CA)
Inventor: DANZIGER YOCHAY
IPC: H01S3/08
Filed: 1998-04-29
Abstract: A discontinuous phase element (86, 204) is disposed between the reflector (20, 23) elements of an optical resonator in order to suppress unwanted modes propagating within the cavity, and to preferentially allow the existence of preferred modes within the cavity. The discontinuous phase element (204) operates by producing sharp changes in the phase distribution of the undesirable modes, so that their propagation losses are sufficiently high prevent their build-up. This is achieved by introducing a discontinuous phase change to these modes at locations where they have high intensity. At the same time, the desired modes suffer 0 or 2.pi. phase change, or have low intensity at the discontinuity, and so are unaffected by the discontinuous phase element. Such elements can be used in a single element or a double element configuration, and can be used in passive cavities or active cavities, such as lasers. In addition to being able to improve the output beam quality of a laser by encouraging output of the lowest order mode beam, they can also be used to improve the maximum power output of solid state lasers by encouraging the output of specific higher order mode beams, without limiting dynamic range of the laser. They can also be used to compensate for birefringence distortion in the gain medium.

Abstract: A lightweight explosion-mitigating assembly including at least a containment structure and a door is disclosed. The containment stucture (10) and door (14) each include at least one set of engagement flanges (20, 22, 24, 30, 32, 34).  The flanges are movable between an interlocking arrangement and a non-interlocking arrangement. In the non-interlocking arrangement, the flanges are sufficiently relatively operatively free from each other to permit movement of the door relative to the containment structure between open and closed positions. On the other hand, in the interlocking arrangement, the door is in the closed position and the flanges are both mutually engageable and slidable relative to each other into mutual engagement and out of mutual engagement.  When mutually engaged, the containment-structure flange (20, 22, 24) and the door flange (30, 32, 34) are not pivotable relative to each other between the interlocking and non-interlocking arrangements, yet sliding movement of the flanges relative to each other out of mutual engagement permits at least one of the containment-structure flange and the door flange to be moved relative to each other between the interlocking and non-interlocking arrangements. This structure may be lightweight, especially when elongated flanges are used, and does not rely on the bending stiffness of the structure to mitigate explosive forces.

Abstract: An improved process for fabricating a refractory dielectric article, in particular silica optical fiber, is provided. The fabrication process involves joining of two elongated bodies - typically silica preforms - end-to-end by use of an isothermal plasma torch technique. A long preform made in this manner allows drawing of optical fiber with less down-time and waste than current processes. The plasma torch technique also produces low perturbations within the resultant preform, thereby increasing the amount of usable fiber.
