Abstract: A barge-type wind turbine platform in combination with a heel tank damper includes a barge-type wind turbine platform having a keystone, two pairs of bottom beams, each including two bottom beams connected to opposite sides of the keystone, wherein the combined pairs of bottom beams define a foundation. A U-shaped ballast conduit is mounted or formed within each of the pairs of bottom beams. Each ballast conduit has ballast water therein, the ballast water extending from an outwardly extending portion of each bottom beam of each pair of bottom beams, such that a volume of air is defined between a surface of the ballast water in each outwardly extending portion and an outwardly facing wall of each outwardly extending portion, and an internal damping element is provided within each ballast conduit. A heel tank damper is defined by the ballast conduits and their respective internal damping elements.

Abstract: Motorized thread tensioner for a sewing machine. In one example embodiment, a motorized thread tensioner for a sewing machine may include a first disk, a second disk, a spring, a shaft having threads on a distal end, a nut threaded onto the threads of the shaft, and an electric motor. The shaft may be through the first disk, the second disk, and the spring. The electric motor may be coupled to the nut and configured to rotate the nut in a first rotational direction and a second rotational direction that is opposite to the first rotational direction. The rotation of the nut in the first rotational direction may cause the shaft to travel toward the electric motor. The rotation of the nut in the second rotational direction may cause the shaft to travel away from the electric motor.

Abstract: Graphical user interface virtual control for a controller of a motor. In one example embodiment, one or more non-transitory computer-readable media store one or more programs that are configured, when executed, to cause one or more processors to generate and visually present a graphical user interface (GUI) virtual handwheel for a controller of a motor. In this example embodiment, the GUI virtual handwheel includes a depiction of a circular physical handwheel that includes a side and a fully-depicted front face and that is oriented with a perspective orientation where a vertical dimension of the depiction is greater than a horizontal dimension of the depiction. The depiction is configured, upon receipt of a first input from a user, to send a first electronic signal to the controller of the motor to cause the motor to cause a first effect that corresponds to physically rotating the physical handwheel in a first rotational direction.

In this example embodiment, the GUI virtual handwheel includes a depiction of a physical handwheel that is oriented with a perspective orientation. The depiction of the physical handwheel is configured, upon receipt of a first input from a user along the length of the depiction in a first direction, to send a first electronic signal to the controller of the motor to cause the motor to cause a first effect that corresponds to physically rotating the physical handwheel in a first rotational direction that corresponds to the first direction.

Abstract: Described is a device for generating an acoustic signal in an electrically conductive medium such as salt water. The device of the present invention has a broadband frequency response and supports high bandwidth data transmission. Reliability is improved in comparison to conventional underwater acoustic transmitters as the device includes no moving components. In one embodiment, the device includes a parallel and alternating arrangement of electrodes and magnets. Neighboring electrodes have different voltages and neighboring magnets have opposite pole configurations such that the magnetic fields overlap the currents between the electrodes in the medium. The currents or the magnetic fields are modulated according to a data signal to generate an acoustic signal in the medium.

Abstract: An integrated automated management system for batch manufacturing of products, particularly pharmaceuticals.

Abstract: A method and apparatus for the repair, reinforcement and protection of damaged upright support members of typical commercial and industrial storage rack systems is disclosed. The invention employs a rigid vertical channel attached to an accommodating base plate to wrap around and bring into secure alignment a damaged upright storage rack support member. The invention is designed to be used to repair damaged upright storage rack support members without requiring the disassembly of the storage rack or the removal of product being stored on the rack.

Abstract: A blade for a fan or blower which has an abrupt transition region between an inner blade region which has a negative leading edge sweep angle, and an outer blade region which is highly forwardly swept. The outer blade region is further characterized by a blade chord that increases with increasing radius. The fan provides a low pitch width and superior noise and efficiency trade-offs.
