Abstract: A pathogen detection and display system is configured to discover and display the location of substances of interest, particularly pathogens that can spread infection. The detection and display system can be used in healthcare facilities on surfaces, medical equipment and devices, patients, and staff, for example.

Abstract: A transparent radiation shield, attachable to a patient support platform, and movable to shield a physician from imaging radiation, includes a transparent computer display that is controllable to provide a data overlay on the shield pertaining to patient data and/or x-ray images.

Abstract: The present invention provides a method of forming a desired pattern with a coating on a substrate. The method includes the steps of applying a water soluble resist material in a predetermined pattern to a surface of a substrate, drying the resist material, depositing a coating on the surface of the substrate to form a coated substrate, wherein a portion of the coating overlays the resist material, and dissolving the resist material on the coated substrate with water to remove the resist material and corresponding overlaying coating and form a desired coating pattern on the substrate surface. The dissolving step preferably includes the step of directing high temperature and high pressure water sprays at the surface of the coated substrate to wash off the resist and corresponding overlaying coating. The removal of the resist material may include a prewash operation wherein the surface of the substrate is wetted with water and coating is allowed to soak.

Abstract: The present invention provides a transparent antenna for an automobile. The antenna includes a glass substrate a first electroconductive antenna element positioned on a central portion of a major surface of said substrate, a second electroconductive antenna element positioned on the major surface of the substrate, spaced from the first element, and at least one electroconductive connector extending between the antenna elements and overlaying and electrically interconnected with a portion of both the first and second antenna elements. A portion of the connector extends beyond the periphery of the glass substrate to be connected to an external connector. The first element and preferably both elements are a transparent, electroconductive coating. In one particular embodiment of the invention, the first element is spaced from the peripheral edge of the substrate and the second element is positioned between the first element and the substrate edge.

Abstract: An electronic pneumatic limb control system for a pneumatically actuated flexible limb is disclosed. The system includes a computer for providing signal data corresponding to a plurality of successive events of air introduction and non-air introduction, respectively, into the flexible limb during a predetermined limb movement. The computer signal data provides for time-varying the air introduction to the non-air introduction for the successive events thereof during the limb movement so as to minimize oscillation and overshoot. The system also provides for successive events of air exhaustion and non-air exhaustion to return the limb to a position of rest after the predetermined limb movement.

Abstract: A moisture sensor to sense rain on a windshield. The sensor members on the outboard surface of the windshield are uncoated and directly exposed to any moisture accumulation on the sensor. Leads connect the sensor to an electrical signal generator and receiver and are insulated from each other to prevent direct electrical interconnection therebetween and subsequent shorting of the sensor circuitry. When moisture is on the sensor, the nature of a monitorable electrical signal passing through the sensor changes and is detected. In response to the altered signal, the windshield wipers are actuated.

Abstract: A rain sensor for a windshield having two sets of electroconductive coatings on opposing major surfaces of the outer glass ply of a windshield. The first set of coatings on the outer major surface of the ply are electrically insulated from but in close proximity to each other. The second set of electroconductive coatings are positioned within the windshield between the glass plies and are electrically connected to a signal generator and receiver. Water contacting the outer surface of the glass ply changes the nature of an electrical signal passing through the first pair of electroconductive coatings. In response to the altered signal, a controller actuates a windshield wiper arrangement to clear the viewing area of the windshield.

Abstract: A fluid actuated limb comprising an elongate flexible core member having a first plurality of bellows extending parallel to the core member and being radially spaced from the core member around substantially the entire circumference thereof. A second plurality of bellows are radially spaced from the core member and helically wrapped around the length of the core member in a first helical direction, and a third plurality of bellows are radially spaced from the core member and helically wrapped around the length thereof in a second helical direction opposite to the first helical direction. Fluid air pressure selectively applied to the limb results in limb movements including extension and contraction, bending with resistance to torsion, right hand and left hand rotation, and combinations of the aforementioned movements.

Abstract: A hammer has a head having a recessed face. The recess in one modification is formed by having four isosceles triangular slanted sections extending inward from the outer edge of the face. In another modification the face has a curved recess. The hammer head has flat exterior side surfaces and the head is positional close to the center line of the handle. The hammer claw has a rectangular notch between the two claw fingers, making the claw especially adaptable for disengaging tie-wire loops or bolt ends with slots in their outer ends. The hammer is useful for driving objects such as nails, pins, and wedges, and is especially useful in work involving concrete forms.

Abstract: This invention relates to press polishing transparencies for lightweight aircraft comprising at least one exterior sheet of acrylic resin involving the use of a polycarbonate pressing plate against the acrylic resin sheet. Both the polycarbonate pressing plate and as many sheets of acrylic resin as are included in the laminate may be press polished while flat by pressurized engagement against a smoothly surfaced flat glass pressing mold. Then, the polycarbonate pressing plate and as many sheets of acrylic resin as are included in the transparency are sag bent to conforming shapes with optional vacuum forming. The polycarbonate pressing plate so shaped is used directly against an acrylic resin surface without any parting material therebetween to press polish the outward facing surface of the acrylic resin sheet(s) so shaped and simultaneously laminate the shaped acrylic resin sheets when the latter are assembled with one or more layers of flexible interlayer material.

Abstract: Apparatus and method are provided for cyclically controlling the metering of photosensitive sheet material into an exposure station, cutting the material to a selected length, exposing the material to form a latent image thereon and advancing the sheet onto a rotating drum upon which the sheet is processed by the application of heat. To minimize the size of the apparatus and to reduce the time between exposures of successive prints the drum is made relatively small but rotated at a correspondingly higher rate with appropriate processing time provided by having each portion of the sheet remain on the drum for more than one revolution of the drum. Rotation of the drum is controlled by a counting mechanism to ensure that the drum has turned a sufficient number of revolutions to fully process the sheet and remove same from the apparatus. The apparatus also controls a stripper element so that this element is actuated at an appropriate time in a print cycle to remove the processed sheet from the drum.
