| 20090117761 | ELECTRICAL FITTING AND SAFETY COVER - A safety cover for a socket or switch has a frame arranged to extend on three sides of a rectangular faceplate of the socket or switch and a cover panel hinged to the frame for pivotal movement towards and away from a position in which the cover panel conceals the faceplate. The frame is of U-shape and defines an opening in which the faceplate is received. The frame has inwardly directed lips contiguous with a rear face of the frame that locate behind the faceplate on opposite sides of the opening clear of the fixing screws used to secure the faceplate to a mounting box. The safety cover can be fitted by partially releasing the screws and sliding the lips under the faceplate as the frame is positioned around the faceplate and then tightening the screws to secure the faceplate and hold the frame in place by securing the lips under the faceplate. | 05-07-2009 |

| 20110149249 | Projection Apparatus and Method for Pepper's Ghost Illusion - An image projection apparatus includes a projector, a frame, and a partially transparent screen. The frame retains the screen under tension, such that the screen is inclined at an angle with respect to a plane of emission of light from the projector. The screen has a front surface arranged such that light emitted from the projector is reflected therefrom. The projector projects an image such that light forming the image impinges upon the screen such that a virtual image is created from light reflected from the screen, the virtual image appearing to be located behind the screen. | 06-23-2011 |

| 20110149248 | METHOD AND SYSTEM FOR FILMING - This invention concerns a method of filming a subjected to be projected as a Pepper's Ghost image. The method may comprise filming a subject under a lighting arrangement having one or more front lights for illuminating a front of a subject and one or more backlights. The lights may be controlled such that the total brightness of the one or more front lights, as measured of the subject, is less than or approximately the same as the total brightness of the one or more backlights, as measured at the subject. The subject may be located directly above one or more floor lights such the subject is illuminated from below by the one or more floor lights. The lights may comprise one or more LEDs. A drop-off distance of the front lights may be less than a distance between the front lights and a backscreen. The invention further concerns a lighting control system comprising an input device for receiving inputs on characteristics of the subject to be filmed and a controller arranged to determine from the inputs a required configuration for the lamps and send control signals to at least one of the lamps to cause the lamps to adjust to the required configuration. The lighting system may comprise a controller connected to a data link providing data on a lighting environment at a location where the film of the subject is being projected as a Pepper's Ghost image, the controller controlling the lamps to adjust configuration during filming in response to data on changes in the lighting environment. | 06-23-2011 |
| 20110157297 | LIVE TELEPORTING SYSTEM AND APPARATUS - A telepresence system comprising a projector for generating an image, a projection screen for reviewing the image generated by the projector and generating a reflected image and a foil for reviewing the reflected image generated by the projection screen. The foil generates and directs partially reflected image toward an audience, the partially reflected image being perceived by the audience as a virtual image or hologram located on a viewing stage. The system may comprise a camera for filming an individual through the foil, the camera being located on a camera side of the foil and positioned adjacent to the viewing stage, the individual being located on an individual side of the foil and positioned on a filming stage. The system may comprise a frame for providing support to the projector and foil, the projector being connected to the frame and the foil being connected to the frame using a tensioning device, the tensioning device being capable of variably adjusting tension along at least one edge of the foil so that the foil remains substantially flat and smooth. The system may comprise a video wall, the foil reflecting the image generated by the video wall. The system may comprise a parabolic mirror for reflecting the image generated by the display device toward an audience, thereby producing a reflected image that is perceived by the audience as a hologram positioned between the parabolic mirror and the audience. | 06-30-2011 |

| 20100270151 | METHOD FOR MANUFACTURING AN ENZYMATIC REAGENT INK - A method for manufacturing an enzymatic reagent ink for use in analytical test strips (such as electrochemical-based analytical test strips configured for the determination of glucose in blood) includes determining a first relationship between wetability of a representative hydrophobic silica material (e.g., a hydrophobic fumed silica material) and at least a first calibration characteristic (for example, a calibration slope) of an analytical test strip that includes an enzymatic reagent ink containing the representative hydrophobic silica material. In the method, the first relationship defines a minimum wetability that provides an acceptable first calibration characteristic. The method also includes determining a second relationship defining wetability of a mixture of a particular hydrophobic silica material and a particular surfactant across a range of relative amount of the particular hydrophobic silica material and the particular surfactant and, subsequently, combining an amount of the particular hydrophobic silica material, an amount of the particular surfactant, and an amount of enzyme (such as glucose oxidase) to form an enzymatic reagent ink. Moreover, the amounts of the particular hydrophobic silica material and the particular surfactant are predetermined based on the second relationship to provide at least the minimum wetability defined by the first relationship. | 10-28-2010 |
| 20100270152 | ENZYMATIC REAGENT INK - An enzymatic reagent ink includes an amount of hydrophobic silica material (e.g., a fumed silica material), an amount of surfactant (such as a non-ionic surfactant); and an amount of enzyme (for example, glucose oxidase). The amounts of the hydrophobic silica material and the surfactant present in the enzymatic reagent ink is predetermined based on first and second relationships. The first relationship is a relationship between wetability of a representative hydrophobic silica material and a first calibration characteristic of an analytical test strip that includes an enzymatic reagent ink containing the representative hydrophobic silica material. In addition, such a first relationship defines a minimum wetability that provides an acceptable first calibration characteristic. The second relationship is a relationship defining wetability of a mixture of the hydrophobic silica material and a surfactant across a range of relative amounts of the hydrophobic silica material and the surfactant. The amounts of the hydrophobic silica material and the surfactant in the enzymatic reagent ink are predetermined to provide at least the minimum wetability defined by the first relationship during manufacturing of the enzymatic reagent ink, and therefore, an acceptable first calibration characteristic. | 10-28-2010 |
| 20100273249 | ANALYTICAL TEST STRIPS - An analytical test strip includes a substrate and a reagent layer disposed on a portion of the substrate. The reagent layer includes an enzymatic reagent ink comprising an amount of hydrophobic silica material, an amount of surfactant; and an amount of enzyme. The amounts of the hydrophobic silica material and the surfactant in the enzymatic reagent ink is predetermined using a first relationship and a second relationship. The first relationship is between wetability of a representative hydrophobic silica material and at least a first calibration characteristic of an analytical test strip that includes an enzymatic reagent ink containing the representative hydrophobic silica material. In addition, the first relationship defines a minimum wetability that provides an acceptable first calibration characteristic. The second relationship defines wetability of a mixture of the hydrophobic silica material and the surfactant across a range of relative amounts of the hydrophobic silica material and the surfactant. The predetermined amounts of the hydrophobic silica material and the surfactant employed in the enzymatic reagent ink provide at least the minimum wetability defined by the first relationship during manufacturing of the enzymatic reagent ink and, therefore, an acceptable first calibration characteristic. | 10-28-2010 |
