Title: System for providing adjustable occupant space in a vehicle
Inventor: TIEDGE ROBERT
IPC: B60P3/34
Filed: 1997-01-03
Abstract: A system for varying space of a vehicle having a fixed portion with occupiable space and a number of ground engaging wheels coupled to the fixed portion. An expandable portion is coupled to the fixed portion and has a rigid floor. The expandable portion is movable relative to the fixed portion to adjust volume of a living space defined by the fixed and expandable portions. The floor is configured for planar movement along a generally horizontal plane when the expandable portion is moved. The system has a first load bearing arm engaging the floor to support the expandable portion. The first load bearing arm is pivotally anchored to the fixed portion to rotate about a generally vertical first axis to correspondingly move the expandable portion. Also, the system has an operator controlled actuator coupled to the first load bearing arm to selectively rotate the first load bearing arm and thereby control position of the expandable portion relative to the fixed portion to provide adjustment of the living space. The system may also include multiple swing arms controllably linked by a rod to facilitate tandem rotation.

Title: Process and device for coating a substrate surface
Inventor: LOHWASSER WOLFGANG
IPC: C23C14/30
Filed: 1997-01-09
Abstract: In a process for coating a substrate surface with a layer of inorganic material (38), the inorganic material is vaporised in a vacuum chamber evacuated to at least 10-3 mbar by bombarding with an electron beam from a high voltage electron-beam gun (10) and deposited on the substrate surface. Gas discharging is created between the point of incidence (A) of the electron beam (16) on the inorganic material (38) to be vaporised and an anode (20) such that the electrostatic charge created by the high voltage electron-beam gun (10) flows off via the anode (20). This way damage to the substrate, which may arise as a result discharging phenomena, can be effectively avoided.

Patent CA-2220544-A1 (CA)
Title: Torque splitting device with an improved curve turning property
Inventor: OHKUMA SHINJI
IPC: B60K23/04
Filed: 1997-11-10
Abstract: In a torque splitting device for distributing an input torque applied to an input member to a pair of output members adapted to be coupled with right and left driven wheels of a vehicle at an adjustable distribution ratio, the distribution ratio is determined in such a way that the understeer and oversteer tendencies of the vehicle under a positive or negative drive condition while turning a curve is appropriately controlled. In particular, it is highly desirable to prevent an understeer tendency from appearing while turning a curve. Therefore, when the vehicle is under a positive drive condition while turning a curve, a yaw moment is produced by an appropriate torque distribution which assists the vehicle to turn in such a way that the understeerg condition is canceled. Furthermore, when the vehicle moves on from a positively drive condition to a negative drive condition while turning a curve, a slight oversteer tendency is produced with a minimum time delay so as to avoid any transient phase of an understeer condition from appearing.

Patent CA-2223343-A1 (CA)
Inventor: WELZ JAROSLAV
IPC: B63B34/56
Filed: 1997-12-03
Abstract: A personal watercraft or "water walker" has two independent elongated, narrow floats. One float can be worn on each leg of a user. Each float has an oarlock mounted on a support. The oarlocks each hold an oar. The supports hold the oarlocks in front of the user's body, above outer edges of the floats. The user can glide across the surface of a body of water with an action similar to cross country skiing. The oars prevent backslip of the non-striding float. The water walker uses both arm and leg propulsion, and thus can provide a user with all around exercise. The floats may each have a main float body coupled to a smaller pontoon. Such floats provide good tracking without requiring the user to adopt an uncomfortably wide stance. The watercraft may optionally have a cross member for linking the two floats together in a parallel spaced apart relationship. A seat is located on the cross member. The watercraft may then be rowed like a standard row boat.

Abstract: The present invention relates to sequence data bases and more particularly, to the use of the information in these data bases to identify RNA motifs therein. More particularly, the invention relates to the use of a search engine which compares both primary and secondary structure of RNAs to identify functional RNA motifs in sequence data bases and to methods of identification of functionally relevant RNA motifs in sequence data bases using such search engines. The present invention further relates to the identification of specific RNA structural motifs in the sequence data bases such as the tat-binding element (TBE), the Rev-binding element (RBE), the hammerhead, a UV-loop motif, a neomycin binding motif and a paromomycin binding motif. In addition, the present invention relates to the validation of the approach of the present invention for indentifying functionally relevant RNA motifs by showing that a previously undiscovered RNA catalytic motif found in the Schistosome genome (DNA) sequence has catalytic activity.

Title: Method and system for post-processing differential global positioning system satellite positional data
Inventor: NELSON FREDERICK
IPC: G01S5/00
Filed: 1998-03-09
Abstract: In a DGPS, accurate post-processed corrections to user receiver locations are made while minimizing the amount of data required to be stored at reference station and user receiver positions.  Further, such corrections are available even if reference station corrections cannot be received by the user in real-time.  The user receiver acquires in-view GPS satellites, computes, and stores user stand-alone position, time of computation, and acquired satellite identification.  Reference stations generate correction data for the same satellites at the same time period, which correction data are broadcast but need not be received by the user in real-time.  Almanac information for the relevant satellites is also made available to at least the user receiver.  Stand-alone user receiver positional data and the almanac data for the same acquired satellites are used by a CPU, located at a remote site able to receive reference station transmissions and/or in the user receiver, to compute corrections to user receiver positions.

Abstract: A bifurcated stent graft (18, 92, 122, 130, 144) implantable in branched interna l passageways includes an open-frame stent latticework (34, 94, 126, 146) formed o f helically wound structural strands(36), and a graft sleeve(40, 110, 124, 132, 150, 152)for med of interwoven textile strands (60). The sleeve is substantially impervious to fluid s and is adjustable along with the graft between a nominal state and radially-reduced axially-elongated state, according to substantially the same relationship of rad ial reduction versus axial elongation. The sleeve and stent are bonded to one another at least at pro ximal and distal end regions of the stent graft. The sleeve preferably is surrounded by th e stent, and incorporates a flow dividing feature in the form of an axially extending seam (5 6, 112, 114, 134, 136). The seam brings together portions of the sleeve that otherwise would be circumferentially spaced apart in the tubular sleeve shape. The stent latticewor k and graft sleeve can be coextensive, the sleeve can extend distally beyond the latticework , or the latticework can extend proximally beyond the sleeve, depending on the intended u se. In other alternative embodiments, the sleeve can surround the latticework.
