Title: Fiber optic fabry-perot interferometer and associated methods
Inventor: RUMPF RAYMOND C
IPC: G01B9/02
Filed: 2003-10-07
Abstract: The method for making the fiber optic Fabry-Perot sensor includes securing an optical fiber to a substrate, and forming at least one gap in the optical fiber after the optical fiber is secured to the substrate to define at least one pair of self-aligned opposing spaced apart optical fiber end faces for the Fabry-Perot sensor. Preferably, an adhesive directly secures the at least one pair of optical fiber portions to the substrate. The opposing spaced apart optical fiber end faces are self-aligned because the pair of optical fiber end portions are formed from a single fiber which has been directly secured to the substrate. Also, each of the self-aligned spaced apart optical fiber end faces may be substantially rounded due to an electrical discharge used to form the gap. This results in integral lenses being formed as the end faces of the fiber portions.

Patent CA-2450357-A1 (CA)
Title: Haptic interface
Inventor: HARDWICK ANDREW JOHN
IPC: G06F3/01
Filed: 2002-07-05
Abstract: Simulated textures whose parameters are held with object model data in a data store (5) are modified in accordance with data held in a data store (6) which data defines a Gamma correction factor (73) previously determined for each identified user. The gamma correction factor is determined by outputting to a Haptic Output interface a texture simulation comprising spaced grooves or ridges. By correlating user response to the perceived "feel" of the texture (rough, medium or smooth scale for example) the user's perceptual factors can be determined. Subsequently applying the perceptual factors to effect a mathematical adjustment (power) of texture in simulation algorithms allows output simulations to be adapted so that each user has a corresponding perception of the simulated objects.

Title: Portable battery operated electronic interactive electric arc detector
Inventor: AUBERTIN DANIEL J
IPC: G01R31/02
Filed: 2004-03-03
Abstract: The invention provides an improved system for the detection of arc faults specifically a portable battery powered interactive electrical arc detection instrument that is both responsible for and responsive to the elicitation of electrical arcs caused by mechanical vibrations being impinged upon electrical apparatus and its support structure thereby influencing the associated wiring of the said apparatus. This is accomplished by a procedure the present inventor calls the bang test utilized by one embodiment of the present invention, specifically the embodiment with the said hammer shaped member, whereby mechanical vibrations are transferred to electrical conductors associated by proximity with the said electrical apparatus. The said bang test provides said mechanical vibrations of various intensities that are impinged upon the wiring of said apparatus in order to elicit arc responses from loose or shorting electrical conductors that supply current to a load.  The elicited response would be an arc produced when the said conductors make and break a flaw of electrons as a result of the influence of the mechanical vibrations. The said invention utilizes electronic circuitry to amplify and shape an arcs electromagnetic characteristics, The said arcs characteristics are picked up by an antenna that is in close proximity to a point of impact between a hammer like portion of the present invention and electrical apparatus. The antenna is placed inside the said hammer shaped member of one embodiment of the present invention that when used as a hammer serves as the source of the mechanical vibrations. A response from the present inventions electronics to the presence of an electric arc is given in the form of visual and auditory stimulus. The described invention and method of usage provides a basis for an electrical troubleshooting system that also offers preventative maintenance of various alternating current and direct current electrical systems. Also offered, as an alternative to the bang test is the use of a vibrator, which serves as the source of the said mechanical vibrations and as an antenna.

Title: Protein containing a burp domain
Inventor: XIA QUN
IPC: C12N15/82
Filed: 2003-08-01
Abstract: The anther recruits a number of specific-genes to support microspore development. Here we report identification of a novel gene, RAFTIN1, from bread wheat and rice, encoding a protein containing a BURP domain hallmarked with 4 CH repeats at its C-terminus. This single copy gene (per haploid complement in cereals) is exclusively expressed in the tapetum during postmeiotic stages when the young microspore undergoes rapid expansion. RAFTIN1 is biosynthesized in the tapetum, transported into the Ubisch body, and further deposited onto the microspore exinewall. Transgenic rice, in whi ch RAFTIN1 expression is down-regulated, shows normal growth and development bu t also shows male sterility. In the RAFTIN1-less anther, tapetal degeneration is retarded and pollen lacks contents. Thus, RAFTIN1 assembly in the Ubisch bod y and the microspore exinewall is required for microspore development, probabl y for regulation of metabolite transport from the tapetum to the microspore. Silencing or knocking-out of RAFTIN will find utility in breeding programs wherever male sterile lines are required.
