  • Patent number: 11476641
    Abstract: A window material for protecting near infrared light emitting lasers and or detectors is coated with a conductive coating that reduces the reflection at the wavelengths and angles of incidence of interest. The conductive coating allows the window to be heated by applying a bias across connected electrodes to remove or prevent the condensation of liquid water and the buildup of ice. The conductive material in the coating has some optical absorption in the hear infrared region of about 800 to 1600 nm, which in combination with multiple intervening dielectric layers also allows the transmission of 90% of the light while obtaining a resistance of less than about 30 Ohms-square. The coating reduces reflection loses from the window, without decreasing transmission by more that about 10%.

  • Publication number: 20160050722
    Abstract: A microwave heating device for activating a microwave-activatable foam insulating material within the dual sidewalls of a beverage cup. The device has a waveguide that defines an exposure chamber for the articles. The waveguide has a plurality of 90-degree twisted rectangular sections, for rotating a perpendicular microwave field pattern along the length of the waveguide. A continuous flexible belt made of a dielectric material passes into and through the exposure chamber along a conveying path, and is formed and maintained into a curled shape in cross section through the exposure chamber to retain the untreated beverage cup upon the curled belt.

  • Patent number: 8123526
    Abstract: A simulated real-time environment employs a plurality of computer controlled video projectors and screens at least fore and aft of a participant-trainee to present life-size displays mutually coordinated to represent views of a same environment from a participant's perspective, each screen representing the participant's view looking in a different direction. In response to a participant's actions, the computer seamlessly changes a projected video to match the participant' actions and maintain a scenario consistent between the two screens. The participant uses a light-emitting simulated firearm or his own firearm loaded with a light-emitting cartridge and/or other equipment with which he is familiar, such as a modified or simulated flashlight, taser, chemical spray container or the like, tethered or untethered by a communication wire, to respond to a simulated situation, which response detected and interpreted by the computer to direct a branch in the projected videos and even shoot back a simulated bullet.

  • Publication number: 20080312964
    Abstract: The present invention relates to a system and method for managing the business of providing home health care. It facilitates the matching of a health care worker to a client based upon the attributes the health care worker possesses and how those attributes match the needs of a client. In addition there is provided a component for the creation and generation of smart forms which allow the health care worker to enter and track information on visits to a client via a computing device. The completed forms then being accessible for billing and data mining.

  • Publication number: 20060191918
    Abstract: A device (22) for heating a food product (P). The device (22) including an oven enclosure (52) at lest one magnetron for emitting microwave energy and a microwave energy focusing device (68, 70, 72) associated with at least one magnetron (56, 58, 60, 62, 64 and 66) and adapted to focus microwave energy towards the food product. The magnetron(s) is/are disposed external the enclosure (52) and the microwave energy focusing device(s) is/are disposed internal the enclosure (52). Also disclosed is a food product support device (116) of a substantially truncated conical external shape with a first larger base surface (118) adapted to be positioned adjacent the base of the oven enclosure and a second smaller supporting surface (120) adapted to support a food product (P) in a position vertically displaced from the base of the oven enclosure for heating and a sloping side surface (122) extending between the base and support surfaces.

  • Patent number: 7030770
    Abstract: There is provided a hydrogen storage system having one or more hydrogen storage containers disposed in a confined area with a vent line extending from the one or more storage containers to a location outside of the confined area. One or more sensors are disposed in the confined area for detecting one or more pre-determined unsafe conditions relating to the storage of hydrogen in the contained area and at least one actuator is provided for actuating an operable valve of the vent line to release the hydrogen from the hydrogen storage container to a location outside the confined area at a pre-determined release rate in response to a signal from the sensor indicating an unsafe condition. A power system incorporating a hydrogen storage system as described above is also provided.

  • Patent number: 4824108
    Abstract: A rebounding ball game comprising a circular planar horizontal court and a deflecting element having a spherical concave rebound surface mounted generally orthogonal to the court, such that a substantial portion of the rebound surface extends above the court and a substantial portion of the court extends forwardly of the rebound surface. Players position themselves on generally opposite sides of the court forwardly of the rebound surface and propel a ball against the rebound surface to deflect onto the court in order to score points. The court may be provided with an aperture defining an out-of-play region, and may be elevated by a tripod or other suitable support. In another embodiment, the deflecting element may be pivoted on a support to be displaced from a position in which it is mounted orthogonal to the court to a position in which it is supported horizontally above the court and shields the court from adverse weather conditions.
