Patent number: 11931623Abstract: An apparatus enabling a user to perform a simulated bicycling exercise includes a frame, two mounting points defining an axis, the two mounting points comprising an upper rear mounting point comprising an upper rear rotating joint and a lower front mounting point comprising a pivoting connection arrangement proximate to and interacting with the frame, the pivoting connection arrangement comprising at least one resistive element configured to provide resistive force returning the frame to a neutral centered orientation from an off-centered orientation and pedals associated with a wheel and the frame, the pedals enabling the user, when facing forward, to apply force to the pedals and rotate the wheel. The frame is configured to receive forces from the user and dissipate the forces into frame leaning forces such that the user has an ability to cause the frame to pivot about the two mounting points by leaning to one side.Type: GrantFiled: January 31, 2022Date of Patent: March 19, 2024Assignee: Real Ryder, LLCInventors: Colin Irving, John J. Harrington, Brian C. Stewart, Michael S. Lofgren

Patent number: 10438580Abstract: A method for using a loudspeaker array that is housed in a loudspeaker cabinet to present audio content to a listener in a room includes receiving (1) an audio channel that includes audio content and (2) acoustical characteristics of the room. The method also produces (1) a first beamformer input signal from the audio channel and (2) a second beamformer input signal and a third beamformer input signal by decorrelating the audio channel and adjusting the audio channel in accordance with the acoustical characteristics of the room. The second and third beamformer input signals are different de-correlated versions of the audio channel. The method also generates driver signals from the first, second, and third beamformer input signals to drive the loudspeaker array to produce a main beam, a first ambient beam, and a second ambient beam, respectively. Other embodiments are also described and claimed.Type: GrantFiled: June 19, 2018Date of Patent: October 8, 2019Assignee: Apple Inc.Inventors: Simon K. Porter, Sylvain J. Choisel, John C. Stewart

Patent number: 4437984Abstract: Multiple hydrocyclone apparatus including plural loop-like arrays of hydrocyclones is provided with a walkway space inside the innermost array. A passageway is provided to permit entry of an operator into the walkway space for inspection and repair of the inner hydrocyclones. The apparatus may be made in an elongated form to fit available mounting space. Baffles may be provided within the feed plenum for directing the flow of feed stock. Appropriate devices may be provided for bleeding minor portions of the feed stock from the feed plenum to maintain the velocity of the stock flowing within the plenum.Type: GrantFiled: April 5, 1982Date of Patent: March 20, 1984Assignee: Clark & Vicario CorporationInventors: Stephen J. King, Bruce S. Moffatt, John C. Stewart
