Patent number: 8705748Abstract: Embodiments of a virtual surround-sound system and methods for simulating surround-sound are generally described herein. Other embodiments may be described and claimed. In some embodiments, a processing module may include spatial processor spatially processes surround-left and surround-right channel signals and front-left and front-right channel signals and combines the spatially-processed signals for providing to drivers of center speaker after crosstalk cancellation and combining with a center-channel signal. In some embodiments, the processing module may include circuitry to cause the spatial processor to refrain from spatially processing either the front-left and front-right channel signals when front-left and/or front-right speakers are connected.Type: GrantFiled: May 4, 2007Date of Patent: April 22, 2014Assignee: Creative Technology LtdInventor: Martin Walsh

Patent number: 7579715Abstract: A device for contactless electrical power transmission in a system including at least one stationary and one moving part, power being transmitted between the at least one stationary part and the at least one moving part includes an inductive transformer including a primary winding disposed on the stationary part and a secondary winding disposed on the moving part, the inductive transformer bridging an isolating point between the stationary part and the moving part. The device also includes a frequency generator having a series-resonant circuit capacitor connected to the primary winding and at least one actuator control element connected to the secondary winding and including a matrix arrangement of a plurality of switchable power semiconductors. At least portions of the inductive transformer, frequency generator and at least one actuator control element are disposed in an area of a rotor shaft and a rotor head of a rotary-wing aircraft.Type: GrantFiled: December 13, 2003Date of Patent: August 25, 2009Assignee: Eurocopter Deutschland GmbHInventors: Anton Seelig, Dieter Reiners, Juergen Luther

Patent number: 4272688Abstract: A strip break detection system is disclosed for a process line in which strip material is being payed out from a payoff reel to a rewind reel. The system is digital, and is based on the concept that for normal mill operation, with continuous strip being payed out from a payoff reel to a rewind reel, equal increments of rotation of the rewind reel, results in ever increasing increments of rotation of the payoff reel. A payoff counter is coupled to the payoff reel. The break detection system is controlled from a rewind counter coupled to the rewind reel which triggers a sequence controller for comparing the successive counts in the payoff counter to ensure that they are ever increasing under normal processing conditions, if the comparison indicates the converse an alarm is sounded; however, since there may be transient and self correcting conditions in the process line during which the latter count of the payoff counter may be less, the system is desensitized by further comparison with a dead band count.Type: GrantFiled: July 3, 1979Date of Patent: June 9, 1981Assignee: Westinghouse Electric Corp.Inventors: John W. Cook, Voit C. Drankhan

Patent number: 4263578Abstract: An A.C. voltage picked up from the alternator driven by an internal combustion engine is converted into a pulse train signal so that the number of the pulses is counted for a period of time defined by a reference timing signal produced in synchronization with the rotation of the crankshaft of the engine. When the number of the pulses reaches a predetermined value during the period of time, a counter produces an output signal to indicate that the slipping rate of the belt is within a tolerance. On the other hand, when the number of pulses is less than the predetermined number, the counter does not produce an output signal (indicating that the slipping rate is over the tolerance). The output of the counter may be averaged over a plurality of measuring times.Type: GrantFiled: June 4, 1979Date of Patent: April 21, 1981Assignee: Nissan Motor Company, LimitedInventors: Takao Fukuhara, Kunihiro Saito

Patent number: 4187036Abstract: A dual roll vibratory compactor is provided with a single lever control for initiating travel in either direction and then starting the rotation of the eccentric weights to vibrate the rolls. Either or both rolls vibrate at low or high selected frequencies according to travel direction. A mode control switch is provided to provide the desired selections. A switch for reversing the selections is provided to maintain the same selections when the compactor is turned around.Type: GrantFiled: September 7, 1978Date of Patent: February 5, 1980Assignee: Rexnord Inc.Inventors: Edwin J. Haker, Charles F. Riddle, Ralph F. Bielinski
