IPC: G02B27/14
Filed: 1999-07-08
Abstract: A compact high resolution omnidirectional or panoramic viewer has several cameras with a common virtual optical center. The field of view of each of the cameras is arranged to form a continuous 360 degree view of an area when taken as a whole. The cameras are positioned so that they each view a different reflective surface of a polyhedron such as a pyramid. This results in each camera having a virtual optical center positioned within the pyramid. The cameras may be positioned so that their virtual optical centers are offset from each other. The offsets produce narrow blind regions that remove image distortions received from the edges of the pyramid's reflective surfaces. The reflective pyramids may be stacked base to base or nested within each other to produce a more compact panoramic viewer. Using two or more reflective pyramids in such close proximity permits using many cameras with the same virtual optical center. Using many cameras divides a large viewing area into many smaller areas where an individual camera views each smaller area. Since each camera views a smaller area, increased resolution is provided to the user.

Title: Protease inhibitor assay
Inventor: TILLOTSON BONNIE
IPC: C12Q1/37
Filed: 1998-03-06
Abstract: Heterogenous and homogenous assays are provided for the detection of protease inhibitory activity in a sample or target compound, taking advantage of the chemiluminescent characteristics of 1,2-dioxetanes. In the heterogenous assay, a peptide bearing a cleavage site for the protease of interest is provided with a first member of a first ligand binding pair at one end, and a first member of a second ligand binding pair at the other end. The other member of the first ligand binding pair is attached to a surface, which binds the peptide, or protease substrate, to the surface. The peptide substrate is combined with the protease and target compound or sample. Substrate cleavage, if not inhibited, is allowed to occur, and any unbound cleaved fragments are removed. An enzyme complexed with the second member of the second ligand binding pair is added, and allowed to bind to any of the (uncleaved) first member of the second ligand binding pair remaining. Unbound complex is removed, and a 1,2-dioxetane substrate for the enzyme is added. If any peptide substrate has not been cleaved, the dioxetane will chemiluminesce, indicating inhibitory activity. In a homogenous assay, the same substrate bears at one end a fluorescent energy accepting moiety, and at the other end a 1,2dioxetane or precursor. If the substrate is cleaved by the protease, the dioxetane and the fluorescent moiety are not in close physical relationship, and no energy transfer occurs when the dioxetane is caused to decompose. If cleavage has not occurred, indicating inhibition, when the dioxetane is caused to decompose, energy is transferred to the fluorescing entity, which releases light of a wavelength recognizably distinct from that of the dioxetane.

Title: Broad band digital radio receiver for multicarrier signal
Inventor: POLITI MARCO
IPC: H04B1/30
Filed: 1998-09-10
Abstract: It is described a broad band digital radio receiver for multicarrier signals, such as for instance TACS or GSM, employing a quadrature demodulator (DEMI/Q) to directly shift in base band the radiofrequency signal. To this purpose, a local oscillator is used, having frequency f0 placed at the centre of the radiofrequency BW band, in order that pairs of channels, symmetric versus f0 are superimposed in the lower base half-band. The equivocation originated in the lose band is then solved by second orthogonal demodulators (DEMx/y), of numeric type, which supply pairs of twice demodulated signals that can be grouped in four-equation systems in the four unknown values consisting of the components, in phase and in quadrature, of the two channels of each pair. Subsequent reconstruction networks (RSCOR) solve the relevant systems and give the two components of each single channel for each pair. One (RSBIL) network is foreseen in the receiver, measuring the amplitude and phase dissymmetries in the two branches of the analogue demodulator and supplying four corresponding digital coefficients (a, b, c, d) to the reconstruction network, which is thus able to conunterbalance at output the effect due to dissymmetries.

Inventor: RHEAULT ALAIN
IPC: F02D29/02
Filed: 2000-04-19
Abstract: A watercraft with a steer-responsive throttle generates thrust when the steerable propulsion unit is turned beyond a predetermined angular threshold. The turning of the steering wheel beyond the threshold causes the throttle to be opened so that the steerable propulsion unit produces a thrust at least equal to the minimal propulsive force needed to effectively steer the watercraft. A watercraft equipped with a steer-responsive throttle ensures that there is always sufficient thrust for steering the watercraft even when the operator fails to open the throttle manually. This steer-responsive throttle is applicable to single-engine personal watercraft, twin-engine jet boats or motorboats equipped with swivel-mounted outboard motors. In a first embodiment of the steer-responsive throttle, rotation of the steering wheel beyond the angular threshold causes an actuating cable to open the throttle. In a second embodiment, an electronic control system regulates the throttle by calculating the optimal throttle setting based on measurements derived from a speed sensor, a steering angle sensor and, optionally, a throttle position sensor.
