Abstract: Apparatus, methods, and computer-readable medium are disclosed for controlling positioning of a desk. An exemplary apparatus includes a tabletop, expandable legs, motors, position sensors, a processor, and a memory configured to store instructions. The motors alter a length of one of the expandable legs. The position sensors identify current position of each of the plurality of expandable legs. The instructions cause the processor to receive a sensor signal, a communication signal, or a command signal, receive the identified current position of one or more of the expandable legs, determine a projected length value for the one or more expandable legs responsive to the received sensor signal, the communication signal, or the command signal, and command one or more of the plurality of motors based on the projected length value for the one or more expandable legs and the identified current position of the one or more expandable legs.

Abstract: Methods, systems, and tables are disclosed for charging multiple devices on a surface and providing feedback. An exemplary method includes sensing a location of a wirelessly rechargeable device on a charging surface of the wirelessly charging surface device and wirelessly powering the wirelessly rechargeable device via a portion of the charging surface corresponding to the sensed location of the wirelessly rechargeable device. The method also includes receiving charging status information from the wirelessly rechargeable device and outputting a human perceptible indication responsive to the received charging status information and the sensed location of the wirelessly rechargeable device.

Abstract: A deck extender for a personal watercraft can include a deck member supported in a cantilevered configuration over an edge of the deck of the personal watercraft. The deck extender can include mounting sleeves fixed to an upper deck of a personal watercraft with mounting tabs of the deck member received within the mounting sleeves. The deck member can include mounting mechanisms having a receptacle and a pivoting cleat mounted above the receptacle configured for mounting accessories to the deck member. The deck member can have recessed channel members for mounting accessories.

Abstract: A personal watercraft with cargo-carrying surface and an anchor rail mounted on a surface of the personal watercraft. The anchor rail being adjacent to the cargo-carrying surface and exposed to an environment. The anchor rail can include an outwardly facing surface exposed to the environment, and the anchor rail is secured to the personal watercraft in such a manner that the outwardly facing surface is recessed relative to the cargo-carrying surface to form a recess or that the outwardly facing surface is flush with the cargo-carrying surface.

Abstract: A safety strobe light may include a modular design incorporating a body portion, a removable lamp or LED, and a removable means for attachment of the safety strobe light to a boom truck arm. The body portion may be constructed and arranged to house at least a portion of the lamp and means for attachment. The body portion may define a channel constructed and arranged to temporarily and removably attach to an attachment and removal tool attached to a hot stick or similar extension pole. The attachment and removal tool may be constructed and arranged to engage with the channel defined by the body portion, such that safety strobe lights may be attached to and removed from surfaces and objects (such as a boom truck arm).

Abstract: A method for forming a metal beam may comprise: clamping first and second portions of the metal beam in a substantially fixed and in a position whereat the metal beam is rotatable about three axes; applying a net bending force to the clamped second portion of the metal beam at a predetermined angle; sensing twisting of the second portion of the metal beam resulting from the net bending force; and modulating the angle at which the net force is applied to reduce the twisting of the metal beam. As a result, the net bending force is moved toward the shear center and toward being along the principal axis of the metal beam.

Abstract: An apparatus for bending a metal work piece, the apparatus including a press support frame and a bending anvil disposed on the press support frame. A clamp press can be mounted to the press support frame, the clamp press positioned to selectively clamp the work piece over the bending anvil when the work piece is positioned on the bending anvil. A bending press unit can be mounted to the press support frame, the bending press unit including a bending roller oriented to engage the work piece during a bending operation when the work piece is clamped over the bending anvil. The bending press unit is operable to move the bending roller with respect to the press support frame in a first direction and a second direction, the first direction being substantially perpendicular to the second direction. A method of bending a metal work piece with the bending apparatus.

Abstract: A grid composite for protecting men and longwall mining equipment during longwall shield recovery includes a regular polymer geogrid structure formed by biaxially drawing a continuous sheet of select polypropylene material which is heat bonded to a polyester fabric. The grid composite is secured over caving shields of longwall mining equipment during a longwall mining operation. The polymer grid composite is ideal for waste containment structures, backfill barriers, and silt barriers in construction and mining applications. In waste containment and backfill barriers, the grid composite is used to form a containment structure. It principle function is to contain waste material usually consisting of a liquid with some percentage of solids.

Abstract: A communication system is disclosed for transmitting digital information between a central station and a large number of remote stations. Digital information is identified by the relationship between a simple pulse marking signal and a time reference signal which is common to all stations, that is, the time reference signal synchronizes the operation of all the stations. The relationship of the marking signal, which does not in itself carry any digital information, to the time reference signal is initially determined by the content of the digital information. Thus, this digital information can only be subsequently determined by evaluating the relationship between the marking signal and the time reference signal. In this communication system, digital radio wave transmission is used to transmit marking signals between stations and the power lines of a power distribution system are used as the source of the time reference signal.
