Abstract: A retroreflective fabric having a print or coating having retroreflective pattern areas of aligned, hemispherically coated retroreflective microbeads. In one implementation of the invention a breathable and/or moisture management fabric has adhered thereto one or more arrays of dots each comprising a plurality of aligned, hemispherically coated retroreflective microbeads in such a way that the fabric is exposed for breathability and/or moisture management at interstices between the dots. In an alternative implementation, a breathable fabric has adhered thereto one or more arrays of dots each comprising an area of fabric surrounded by an area of aligned, hemispherically coated retroreflective microbeads adhered to the fabric in such a way that the fabric is exposed for breathability and/or moisture management in the dot areas.

Abstract: A video conferencing system has a two-way mirror, which is between the observer and the display device, positioned at an angle to reflect a backdrop surface. The backdrop surface, which is further away from the two-way mirror than the image plane of the image display device, appears superimposed in a position behind the image of a person from the remote location. A camera is located in the backdrop at a position along the line of sight of the transmitted image so that a perceived eye contact is achieved.

Abstract: A gaseous fuel storage system included in a vehicle to supply fuel to a power source (e.g., an engine, fuel cell and the like) is diagnosed and controlled by a monitoring/evaluation and control system. Various parameters with reference to gas temperature, gas pressure, gas density and damage and shock of a vessel containing the pressurized gas are provided by respective sensors mounted on and in vessels of a gas storage system. A control module determines whether maintenance of the vessels is required based on the sensed parameters. If maintenance is necessary, the components will be replaced with new ones or the entire gas storage system or the vessel will be replaced. If necessary, a warning is provided to avoid operation of the power source and the vehicle.

Abstract: A method and apparatus for extending the linear range of a phase detector. In one embodiment, a limited range phase difference is generated between selected edges of first and second input signals, and an excursion of the limited range phase difference beyond a predetermined threshold is detected. In response to detecting the excursion of the limited range phase difference beyond a threshold, an edge of the first or second input signal is prevented from influencing subsequent generation of the limited range phase difference, and a compensated phase difference is generated, derived from the limited range phase difference and including a correction component which compensates for the effect of preventing said edge from influencing subsequent generation of the limited range phase difference.

The light reflective regions could be formed from particles selected from the group consisting of a fine gradation of ground rock, crystal, metal filings, sand, powder, or specially produced three dimensional forms. The screen could be used in an image projection system employing a projector and in a communications system employing a projector, camera, and transmission equipment.

Abstract: The present invention uses the principle that phosphomolybdate binds to hydrophobic surfaces to isolate the phosphomolybdate complex from other phosphate-containing molecules and further uses the SPA concept to bring a radiolabeled phosphomolybdate complex in close contact with a scintillant for measurement by scintillation counting. Generally, the present invention provides an assay for detecting and measuring the amount of orthophosphate (Pi) in an aqueous reaction mixture, wherein the amount of Pi released is separated from the reaction mixture by: adding a solution of molybdate to the reaction mixture to form a phosphomolybdate complex; and contacting the phosphomolybdate complex with a hydrophobic surface, wherein the surface is capable of being separated from the aqueous reaction mixture to allow measurement of the Pi. Particularly, this invention provides an assay for measuring the ATPase activity of enzymes, more particularly, the HPV E1 helicase.

The present invention also provides novel compounds, pharmaceutical compositions and methods for using these compounds and compositions in the treatment or prevention of papilloma virus infection. More particularly, the present invention provides compounds, compositions and methods for inhibiting papilloma virus DNA replication by interfering with the E1-E2 protein-protein interaction essential for viral DNA replication.

Abstract: A system and method for locating objects such as people, pets, and personal articles is described. A transceiver is attached to the person, animal, or item to be tracked and a handheld locator device is employed to transmit a locator signal containing an address code to the transceiver. Upon receipt of a signal, the transceiver compares the address code contained in the locator signal with an address code stored in the transceiver. If the two codes are same, the transceiver sends a return signal back to the locator device. The locator device uses this return signal to determine the distance and/or direction of the transceiver from the user's location. The system allows a user to select from a multiple number of items to locate and allows multiple users to search for different articles within the same general area without interference.
