Abstract: An adjustable windshield assembly for an open-air vehicle has a flexible windshield of sufficient flexibility and resiliency that it can be repeatedly elastically deformed without substantial degradation of strength, stiffness, appearance or translucence. Adjusting the configuration of the flexible windshield affords the rider varying degrees of frontal protection, ranging from a low-drag racing posture offering minimal protection from wind, rain and snow to a less aerodynamic, upright posture offering maximal protection. The configuration of the flexible windshield is controlled by an adjustment mechanism having a bifurcated cable fixed to the flexible windshield such that tension in the cable displaces the flexible windshield with respect to the windshield base thereby deforming the flexible windshield into a plurality of possible configurations. Upon release of the cable tension, the flexible windshield returns to its original, undeformed low-profile configuration.

Title: Mutivariate sample analysis
Inventor: NICELY VINCENT ALVIN
IPC: G01N21/27
Filed: 1997-01-24
Abstract: In a process for analyzing a sample of unknown constitution by an analytical apparatus, a set of analytical measurements and a set of reference measurements, each comprising a set of multivariate signal responses obtained from a set of samples by a first and a second analytical apparatus, are adjusted to remove operational variabilities associated with the apparatus, thereby providing a first and a second matrix of adjusted signal responses.  One of the two matrices of adjusted signal responses is decomposed into a matrix product of a matrix comprising a set of principal factors and a matrix comprising the amounts associated with each of the principal factors. A  compressed signal response matrix product is constructed that comprises a matrix comprising a subset of the set of principal factors and a matrix comprising the amounts associated with each of the principal factors included in the subset. From the latter matrix a projection matrix is computed. Using this projection matrix and a first normalized matrix product that comprises a normalization matrix and the other of the two matrices of adjusted signal responses, a compressed normalized matrix product is constructed. Values of the normalization matrix that minimize the difference between the first normalized matrix product and the compressed normalized matrix product are computed, thereby producing an optimal normalization matrix. A second normalized matrix product comprising the optimal normalization matrix and the one matrix of adjusted signal responses that had been decomposed into a matrix product is constructed. Using the other matrix of adjusted signal responses and the second normalized matrix product, a calibration useful for analyzing the signal responses obtained from the sample of unknown constitution by the first analytical apparatus is constructed and applied to the signal responses from the sample to determine its constitution.

Title: System for human trajectory learning in virtual environments
Inventor: SHADMEHR REZA
IPC: G09B19/00
Filed: 1997-02-12
Abstract: In an apparatus and method for teaching motor skills to a human subject, learning by a student is based upon imitation of a teacher's motion. The teacher's motion is sensed by a motion sensing device, is digitized by a computer, and is then recorded in memory. The computer generates a virtual image sequence of the teacher on the computer display of the teacher interacting in the computer-generated virtual environment for the student to view and imitate. The same motion sensing device used to record the teacher's movement tracks the student's movement and the computer creates a virtual image sequence on the display corresponding to the student's movement and its interaction with the virtual environment in real-time, simultaneously providing an image sequence of the teacher's movement. The student's task is to imitate the teacher's movement. This process is repeated until the teacher's and student's trajectories match well in space and time.

Title: Method and device for directional emission and reception of electromagnetic waves
Inventor: G BEL EWALD
IPC: H01Q13/04
Filed: 1997-12-13
Abstract: The invention relates to a high-mode operating resonator, e.g. a coaxial wave-guide, wherein various oscillation modes of an electromagnetic field are coupled in and superimposed on each other. The mixed mode thus arising from the excitation field is used to excite an antenna, preferably a biconical antenna. The azimuthal emission characteristic of the electromagnetic wave emitted by the antenna has the same dependency as the azimuthal field distribution in the resonator. The emission characteristic has in particular, in the case of an azimuthal and anisotropic excitation field, privileged directions in the azimuthal emission. A change of direction of the maximum emission of the electromagnetic wave occurs through an additional change of the phase or amplitude relationships between the coupled electromagnetic field modes.

Filed: 1997-06-17
Abstract: A resistor has a resistor body (11) of polycrystalline silicon and electric terminals (23, 15) arranged on and/or in the resistor body (11). A resistor portion (13) is thus formed between the terminals, which gives the resistor its resistance. The material in the resistor body is doped with for example boron. In order to block unsaturated silicon bonds in grain boundaries to a sufficient extent and thereby give the resistor a good long-time stability, fluorine atoms are added to the material. They are added in such a high concentration that all of the otherwise unsaturated bonds are coupled to fluorine atoms. Further, it is provided in the manufacture of the resistor that the concentration is maintained at the originally high value. When ion implanting dopants and fluorine atoms it can be accomplished by performing an annealing after implanting dopants at a high temperature and then a further annealing operation at a low temperature after the subsequent implantation of fluorine.

Title: Crosslinking base layer for bondable interlinings in accordance with the double dot technique
Inventor: SIMON ULRICH
IPC: C09J123/02
Filed: 1999-03-01
Abstract: Disclosed is a crosslinkable hotmelt adhesive composition for the coating and/or lamination of sheet-like structures, where a crosslinking component is protected by a polyolefin matrix and is not crosslinked until the composition is melted. The crosslinking component may be a polyisocyanate or epoxide and a main reactive component of the adhesive composition may be an amine-terminated copolyamide or OH-terminated copolyester. Since the crosslinking component is protected by the polyolefin metrix, it does not react with water even when the adhesive composition is used as an aqueous paste, until it is melted.
