Patent number: 8791583Abstract: Mold pieces (105 and 110) for molding a layer of mold compound on the interconnect side of a bumped semiconductor wafer (118) include a primary cavity (117) and secondary cavities (120) into which excess mold compound from the primary cavity (117) flows. The secondary cavities (120) include a plunger (130) that asserts a predetermined backpressure that is equal to a desired mold compound pressure on the mold compound during molding. As most of the excess mold compound in the primary cavity (117) is forced to flow into the secondary cavities (120), this advantageously leaves a relatively thin layer of mold compound on the semiconductor wafer (118), which can then be removed, for example by grinding in a relatively short time. Mold piece (105) further comprises a movable cavity bar (115) that can be moved away from mold piece (105) after molding and be cooled to detach the molded substrate that adheres to the cavity bar.Type: GrantFiled: October 4, 2002Date of Patent: July 29, 2014Assignee: Advanced Systems Automation Ltd.Inventors: Hwee Seng Jimmy Chew, Dingwei Xia

Patent number: 8791584Abstract: A structurally integrated modular system for energy recovery from vehicular traffic as further disclosed. The system comprises an “X” & “Y” axis horizontal array of Linear Electromagnetic Generators, (LEGs), in a close packed hexagonal or other shaped structural grid, as further disclosed. Each LEG is spring-less, using a high strength main core magnet, and a fixed lower magnet to repel the main core magnet at a designed coercive restoring force. The plurality of LEGs are contained within Modular Prefabricated Structural Sandwich Composite Panels, (MPSSCPs), designed to be placed upon a roadway surface, (whose upper surfaces are flexible and lower surfaces semi-rigid). The resultant energy recovery is thereby converted to electric power and heat. The MPSSCPs, and their accessory panels are thereby installed upon a roadway bearing surface to generate clean electric power and heat, which thaws ice and snow, when and where necessary.Type: GrantFiled: June 14, 2011Date of Patent: July 29, 2014Inventor: Charles Martin Sieger

Patent number: 8791585Abstract: A power system comprises a tension harnessing arrangement to harness tension in a tether connected between a tensioning arrangement and storage means. The tension harnessing arrangement of the system comprises at least one first capstan roller arranged in a predetermined configuration. The tether tensioningly abuts at least a portion of the periphery of the first capstan rollers such that there is substantial contact between the tether and the first capstan rollers, thereby engaging the first capstan rollers to generate rotational energy. Alternatively, second capstan rollers engage with the first capstan rollers. At least one converter functionally co-operates with the first capstan rollers, either directly or via the second capstan rollers, for converting the rotational energy to energy in a transmissible form, storage form dissipative form, or a combination thereof.Type: GrantFiled: December 10, 2012Date of Patent: July 29, 2014Assignee: Grant Howard CalverleyInventor: Grant Howard Calverley

Patent number: 8791586Abstract: A tubular housing can include at least one fixed helical vane formed onto the inner surfaces of the tubular housing in a spiral and adapted to direct fluid into a spiraled flow and focus fluid onto a fan blade assembly associated with an alternator system and located within the tubular housing before a system exhaust. A generator cone can be mounted near the center and front of the fan blade assembly facing fluid passing through the tubular housing. As fluid passes over the generator cone it experiences compression between the generator cone and housing resulting in increased pressure and velocity of the fluid, thereby increasing rotational speed of the generator blades and generator as the compressed, spiraled fluid passes through the blades and exits the tubular housing. The system can be used for fixed or mobile applications in water, wind and manually induced fluid flow.Type: GrantFiled: August 3, 2011Date of Patent: July 29, 2014Assignee: MDL Enterprises, LLCInventors: Luis M. Ortiz, Anthony Michael Baca, Donald Wichers

Patent number: 8791588Abstract: A wind turbine is disclosed which uses energy in air moving relatively toward the turbine to focus and increase the velocity of air entering a turbine inlet air flow passage. The inlet flow passage discharges focused and accelerated air to blades of a rotor where the blades interact with that air to turn the rotor. Rotor motion can be used to operate an electrical generator. The plane of rotation of the rotor can be at substantially right angles to the plane of the passage inlet opening. Baffles in the flow passage and stator vanes adjacent the rotor blades cause the mass flow of the accelerated air to be substantially uniform, and desirably directed, throughout the rotor's blade area. The turbine is compact and operates quietly.Type: GrantFiled: January 19, 2011Date of Patent: July 29, 2014Assignee: Wattenberg Industries, LLCInventor: Johann Steinlechner

Patent number: 8791591Abstract: A zero-current switching multiple-output-regulator (“ZCS MOR”) converts power from an input source via a transformer to a main output and one or more auxiliary outputs. Each output is coupled to a respective winding of a transformer preferably by switches controlled as synchronous rectifiers. The synchronous rectifier for each auxiliary output preferably turns on at the start of current flow in its respective winding and off as its respective current returns to zero, independently of the other outputs. The synchronous rectifier for the main output may be held ON until the synchronous rectifiers for each of the auxiliary outputs stop conducting. In the event energy stored in the transformer is insufficient to supply one or more heavily loaded auxiliary outputs, the current in the winding for the main output is allowed to reverse thereby transferring energy from the main output capacitance to the heavily loaded auxiliary outputs. A feed back loop is preferably closed around the main output for regulation.Type: GrantFiled: February 23, 2010Date of Patent: July 29, 2014Assignee: VLT, Inc.Inventor: Patrizio Vinciarelli
