Abstract: An attachment for a projected head mounted display redirects images designed to be projected on retroreflective screens directly back into the eyes of a user. This permits, for example, the head mounted display to be switched from an augmented reality mode to a virtual reality mode. The attachment can be engaged or disengaged from the head mounted display. The attachment includes a freeform prism.

Abstract: A projected head mounted display system is disclosed that projects images onto a retroreflective screen, which are then reflected back for view by a user. The projected head mounted display system displays computer generated images at multiple focal distances to simulate a light field so as to match eye accommodation to vergence.

Abstract: A method and control system control a process line by providing a PLC with control screens each having a unique screen number. Each HMI device is provided access to a first set of the control screens, with displayed buttons labeled with a corresponding one of the control screens. Input signals are received from a requesting HMI device that identifies the requesting HMI device and requests a control action or a monitoring action for a corresponding workstation. Additionally, the requesting HMI device is provided access to a second set of the control screens based on the received input signals, such that the HMI devices share an HMI control template that is also dynamically and individually scalable to the requesting HMI device. The process line is then controlled via the PLC in response to control signals from the HMI devices corresponding to selections from the control screens.

Abstract: A position control system for a manual picking workstation having a plurality of component bins includes a light device and a process controller. The light device projects a light beam along a plane. The process controller includes a processor and memory containing a calibrated assembly sequence and predetermined bin coordinates for each of the component bins. The process controller executes a method to detect, via the light device, an instance of beam breakage wherein the light beam is interrupted or broken, and to determine two-dimensional (2D) coordinates of the beam breakage. The process controller also determines corresponding bin coordinates of an expected bin via the calibrated assembly sequence, compares the determined 2D coordinates to the corresponding bin coordinates, and executes a control action when the determined coordinates do not match the corresponding bin coordinates. The light device may be an oscillating laser scanner or fixed lasers.

Abstract: A treatment protocol by which a renal stone patient is administered a chelating agent, generally once a day and preferably by mouth, during a treatment phase and is later administered the same chelating agent once a week, during a “maintenance” phase. The chelating agent is most preferably ethylene diamine tetraacetic acid (EDTA) and may be provided in a dosage form having an enteric coating and at least one external cathode and at least one external anode to create a galvanic current upon contact of the dosage form with the patient's intestinal contents.

Abstract: Particular nutritional supplements and protocols emphasize the use of ethylenediamine tetraacetic acid as a mouth rinse, and as an enteric-coated oral pharmaceutical, further supplemented on a daily basis with both a combination of phosphatidyl lipids and alpha lipoic acid and a nutritional supplement containing approximately equal amounts of Reishi and Shiitake mushrooms.

Abstract: Pathogens, toxins, and some chemical warfare agents inside an enclosure are destroyed using hydroxyl free radicals. The hydroxyl free radicals can be generated by, for example, reacting ozone with water in the presence of ultraviolet light or reacting hydrogen with nitrogen dioxide in the presence of ultraviolet light.

Abstract: An apparatus for water treatment, and in particular for electrical water purification in combination with a filtering apparatus for providing purified water for drinking and other application common in the home, farm or business. Metal, hydrogen and oxygen ions are introduced into water to be treated by using plasma fused iridium coated titanium electrodes and copper alloy electrodes. After ionizing the water to be purified, the water is then filtered in a filter tank which contains layers of various filtration media, including granular activated carbon.

Abstract: A vehicle flap (10) carried in a rearward position with respect to a vehicle tire (12) including a frame (14) with a pair of substantially parallel side walls (22) substantially perpendicular to and carried by a top member (18). The top member (18) is adapted to be carried by a vehicle (48). Vehicle flap (10) has a front side facing a tire (12) opposite a rear side. A roll base (34) extends outwardly toward vehicle tire (12) from near the bottom of flap (10). Vehicle mud flap (10) also has a plurality of arcuate, angularly-directed parallel vanes (24) which extend between the side walls (22) and extend downwardly from the front side to the rear side of the flap (10). The parallel vanes (24) form a plurality of openings (28) such that the parallel vanes (24) redirect any debris from the rotating vehicle tire (12) downwardly through the debris openings (28) while allowing the flow of air therethrough.

Abstract: A theft deterrent device (10) is provided for enclosures such as dwellings, motor vehicles and the like, having one or more entranceways. The device is adapted to be quickly and easily installed within such enclosures and is connected electrically with pre-existing electrical circuitry of the enclosure, causing the device to emit a noxious gas, upon unauthorized entry into the enclosure via one of the entranceways. The noxious gas renders the enclosure temporarily uninhabitable. The device may be activated or deactivated remotely from outside the enclosure. The device also includes other safety features to prevent accidental discharge of the noxious gas.

Abstract: A beach chair including an integral tubular frame having a top run joined on its opposite extremities with downwardly projecting side legs which terminate at their lower extremities in stakes for being driven into the beach. A tubular headrest is telescoped onto the top run and the upper extremity of a strut projects laterally through such headrest and is rotatably connected with such top run for pivoting from a collapsed position disposed in the general plane of the side legs to a supporting position angled outwardly and rearwardly from such side legs. A web is stretched between the side legs and, if desirable, an apron or flap may project from the lower extremity thereof to serve as a cover over an underlying seating area.
