Patent number: 8700497Abstract: A logical inventory mechanism takes components in assemblies into account when determining purchase requirements. The inventory control system determines assemblies that are available, determines their components and whether or not each component may be reused, then adjusts physical inventory to generate therefrom logical inventory based on physical inventory plus parts in the assemblies that may be reused if the assemblies are disassembled. By computing logical inventory that would be available by disassembling assemblies, inventory levels may be reduced, thereby enhancing the efficiency of an inventory control system that includes the logical inventory mechanism. Assemblies in inventory thus may be used in two very different matters, as the starting point for a higher-level assembly, or to be disassembled to use one or more reusable components in the assembly in a different assembly.Type: GrantFiled: February 21, 2007Date of Patent: April 15, 2014Assignee: International Business Machines CorporationInventors: Timothy James Gerber, Ivory Wellman Knipfer, William Robert Taylor

Patent number: 7878734Abstract: Apparatus embodying the invention include a damping plate attached to the submerged end of a spar-like element floating in a body of water. The spar like element tends to move up and down in a vertical direction in response to passing waves. The damping plate has a pair of oppositely facing surfaces extending transversely to the vertical direction of the movement of the spar-like element and vertical structures (“lips”) mounted on the oppositely facing surfaces for increasing the effective mass of water pushed during movement of the damping plate through the water. Damping plates with lips, as per the invention, may be used in wave energy converters to control the relative motion between the spar-like element and a float to increase the energy produced.Type: GrantFiled: April 30, 2007Date of Patent: February 1, 2011Assignee: Ocean Power Technologies, Inc.Inventors: Diana Bull, James Gerber, William Powers

Publication number: 20070261404Abstract: The invention relates to active impedance matching systems (AIMS) and methods for increasing the efficiency of a wave energy converter (WEC) having a shaft and a shell intended to be placed in a body of water and to move relative to each other in response to forces applied to the WEC by the body of water. The system includes apparatus for: (a) extracting energy from the WEC and producing output electric energy as a function of the movement of the shell (shaft) relative to the shaft (shell): and (b) for selectively imparting energy to one of the shell and shaft for causing an increase in the displacement and velocity (or acceleration) of one of the shell and shaft relative to the other, whereby the net amount of output electrical energy produced is increased. The apparatus for extracting energy and for selectively supplying energy may be implemented using a single device capable of being operated bi-directionally, in terms of both direction and force, or may be implemented by different devices.Type: ApplicationFiled: January 13, 2005Publication date: November 15, 2007Inventors: David Stewart, James Gerber

Publication number: 20070126239Abstract: A wave energy converter (WEC) includes a shell suitable for being placed within a body of water. The shell contains an internal oscillator comprising a “reaction mass” and a spring mechanism coupled between the reaction mass and the shell. The shell and internal oscillator are constructed such that, when placed in a body of water and in response to waves in the body of water, there is relative motion between the shell and the internal oscillator's mass. A power take-off (PTO) device is coupled between the internal oscillator and the shell to convert their relative motion into electric energy. In systems embodying the invention, the spring mechanism is designed such that its displacement or movement is less than the displacement or movement of the reaction mass. The spring mechanism may be any device which enables the reaction mass to undergo a given replacement while its displacement or movement is less than that of the reaction mass. This property enables the size of the WEC to be more readily controlled (e.Type: ApplicationFiled: December 1, 2006Publication date: June 7, 2007Inventors: David Stewart, James Gerber

Publication number: 20070046027Abstract: A wave energy converter (WEC) for converting energy contained in surface waves on a body of water to useful energy comprises two floats movable relative to one another in response to passing surface waves. Both floats comprise expandable outer envelopes which have been expanded into full and firm shape. In one process, expansion is obtained by filling the floats with fluids, for example, air and water. The fluids can be pumped into the floats, or the floats can be mechanically expanded in the presence of the fluids for self filling owing to pressure differentials. In one embodiment, a float envelope can comprise of plurality of end to end connected length sections in nested or telescoped relationship. Expansion is obtained by pulling the telescoped sections out from one and other, for example, by pumping fluids into the telescoped sections.Type: ApplicationFiled: August 25, 2006Publication date: March 1, 2007Inventors: David Stewart, James Gerber

Patent number: 7140180Abstract: A wave energy converter system comprises two floats; a first being generally flat and heaving up and down in phase with passing surface waves on a body of water, and the second being elongated and heaving up and down out of phase with the passing waves. Preferably, the first float is annular with a central vertical opening therethrough, and the elongated float, with a weighted bottom end, extends vertically through the central opening of the first float. The two floats thus move out of phase with one another, thus providing a relatively large relative motion between the two floats giving rise to highly efficient energy conversion. Each float serves as a “ground” for the other; thus avoiding the need for anchoring the floats to the floor of the body of water.Type: GrantFiled: January 22, 2004Date of Patent: November 28, 2006Assignee: Ocean Power Technologies, Inc.Inventors: James Gerber, David B.

Publication number: 20060035768Abstract: An exercise repetition sensor comprises an electricity generator, such as an electricity generator, which is coupled to an exercise system, where the electricity generator is capable of sensing exercise movements of any size or intensity on the exercise system. The electricity generator can be based on a number of electrical, magnetic, or optical sensing principles. For example, an electricity generator comprising an electricity generator includes a spindle that is coupled to one or more parts that move in proportion to an applied force. The voltage-generator generates an electrical current as the spindle moves, and sends the electrical current to an electronic display interface. In one embodiment, the voltage-generator sends a positive direct current through one of two circuit wires to the electronic console, such that the electronic console can immediately identify that the user has performed an exercise repetition.Type: ApplicationFiled: August 11, 2004Publication date: February 16, 2006Inventors: Rodney Kowallis, Darren Ashby, Robert Ashby, James Gerber, Chad Earl, Rick Hendrickson

Patent number: 6772592Abstract: Apparatus for converting energy contained in surface waves on a body of water to useful energy comprises a float from which is suspended a fully or effectively fully submerged inverted cup-shaped member having a closed top end and an open bottom end. Disposed within the top space is a compressible fluid separated by a flexible membrane from a column of water filling the bottom open end of the submerged member. Passing surface waves cause pressure variations at the bottom end of the member causing changes in the water column height and corresponding changes in the buoyancy of the member. The buoyancy changes induce vertical oscillations of the member relative to the float and known means are used for converting the relative movements of the float and submerged member to useful energy. Preferably, the float vertically oscillates in synchronization with the passing waves, and the vertical movements of the float increase the relative movements between the float and the submerged member.Type: GrantFiled: February 4, 2003Date of Patent: August 10, 2004Assignee: Ocean Power Technologies, Inc.Inventors: James Gerber, George W.

Patent number: 6765307Abstract: A wave energy converter (WEC), for use in a body of water of depth Dw, includes a tubular structure and a piston within the tubular structure where the relative motion between the piston and the tubular structure is used to generate electric power. The length (L) of the tubular structure may be selected to have a predetermined value based on the fact that: (a) the efficiency of the power generated by WEC increases as the length “L” of the tubular structure increases from a minimal value until L reaches an optimal value; and (b) the efficiency decreases as L is increased beyond the optimal value due to the increased mass of the water that the tubular structure and the piston have to move.Type: GrantFiled: January 15, 2002Date of Patent: July 20, 2004Assignee: Olean Power Technologies, Inc.Inventors: James Gerber, George W.
