  • Patent number: 10337228
    Abstract: A dual function door acts as both a pocket door and a hinged swinging door. A first door panel is hingedly attached to a wall for swinging. A first header rail is attached to the top of the first door panel while a second header rail is attached to an appropriate surface at the same height as the first header rail. A second door panel has rollers that slide within the first header rail. The first door panel is positionable so that the first header rail and the second header rail align allowing the second door panel to also slide within the second header rail. The two header rails can be locked in the aligned position.

  • Patent number: 9847658
    Abstract: Systems and methods for battery management are disclosed. A system may include an internal control network including multiple node controllers powered by a unique cell or combination of cells of a battery. The node controllers may communicate with each other via a node communication system. Each node controller may be responsible for managing a charge level associated with one or more cells. The one or more devices of the internal control network may enable measurement of environmental factors such as a temperature and a current and voltage applied at the battery. Based on the measured environmental factors, the internal control network may perform an ongoing assessment of the one or more cells of the battery and of an overall battery condition. The internal control network may initiate turning on or off a battery output to prevent over discharge and possible damage to the battery or devices connected to the battery.

  • Patent number: 9542596
    Abstract: Systems, methods, and apparatus to facilitate the production and presentation of strokes gained golf statistics. Some systems include mobile devices for the collection of essential shot data necessary for producing strokes gained statistics during play. The device travels with a golfer, measures and records distance-to-hole automatically using GPS and/or laser and/or radio technology, in combination with one of various lie-type classifications (tee, fairway, rough, sand, green, recovery, penalty, hazards, etc.) before and after a golf shot as selected by the golfer using human judgement. The device transfers essential shot data to a remote database and receives and displays calculated strokes gained results.

  • Publication number: 20150182836
    Abstract: Systems, methods, and apparatus for facilitating the production and presentation of strokes gained golf statistics are described. Some systems include the use of mobile devices for the collection of data during play. The device travels with a golfer and has the means to measure distance-to-hole automatically using GPS and/or laser technology. The device has the means to record shot data before and after a golf shot. The shot data includes the distance-to-hole and lie type of a ball at rest. Lie type is determined by human judgment. The device has the means to transfer data to a database. Some systems may include a database to compile data from mobile devices. The database is arranged to allow for strokes gained analysis of the data, which may be used to generate strokes gained statistics, presented on a computer output system. Related methods also are described.

  • Patent number: 8821103
    Abstract: A lifting system for lifting and lower people between a vehicle door and ground level uses a carriage that is slid underneath and out from the undercarriage of the vehicle. A lift platform is flush with the carriage when stowed and is capable of being raised from this position up to the door and lowered down to the ground. A series of housing are located on the underside of the carriage and have a sprocket gear thereon. Extension arms are attached to each gear and rotatably to a lift platform. Rack gears mesh with the sprocket gears for rotating the arms and thus the platform up and down, the rack gears articulated via one or more hydraulic drives, with rotation of the arms resulting in articulation of the platform.

  • Patent number: 8137538
    Abstract: A compact point of use water purifier intended for both urban and rural areas of developing countries. The purifier is a spigot with an integrated UV radiation source 18 adjacent to an outlet orifice 19 to selectively on demand expose untreated water when the spigot valve 15 is activated to dispense water for consumption. The valve includes a user-activated handle 154 and is configured such that upon initial movement of the handle the ultraviolet radiation source is activated and upon continued movement of the handle the valve is opened. The water purifier is connectable to an electric power source, either 110V/220V AC or 12VDC, via a transformer unit to deliver the appropriate voltage to the spigot unit.

  • Publication number: 20050129563
    Abstract: A method of producing parts from powdered metal comprising the steps of providing a metallurgic powder comprising iron, 0-0.6 weight percent carbon, 0.5-5.0 weight percent silicon, 0.5-6.0 weight percent nickel, 0.5-1.5 weight percent molybdenum, 0-0.7 weight percent manganese, and 12-20 weight percent chromium, the weight percentages calculated based on the total weight of the powder. Secondly, the powders are compressed at a pressure of 35 to 65 tsi to provide a green compact. Then, the compact is heated in an atmosphere to a temperature of 2100° F. to 2400° F. for 20 to 90 minutes, such that the resulting microstructure of the compact is either single phase ferritic or dual phase ferritic and austenitic.
