Patent number: 10550993Abstract: Rotary support systems, associated control devices, and methods of operating the same. Rotary support systems include a mast configured to support an elevated device and a base that includes a rotary mechanism that rotatably couples the mast to the base. The rotary mechanism is configured to selectively rotate the mast. The mast has a cross-sectional profile that is non-circular. Rotary support systems additionally may include a controller configured to interface with an electric motor to rotate the mast with respect to the base. Controller implemented methods for operating a rotary support system include receiving an input command and, responsive to the receiving the input command, sending an output command to an electric motor to rotate the mast relative to the base.Type: GrantFiled: October 28, 2016Date of Patent: February 4, 2020Assignee: MastWerks, LLCInventors: Paul Verstrate, David Haycock, Christopher D. Drummond

Patent number: 8723874Abstract: Methods and apparatus are provided for efficiently and intelligently communicating characteristic information in video graphics switcher environments. An intelligent video graphics switcher obtains display device characteristic information associated with multiple display devices and maintains updated characteristic information. When an event such as a connection/disconnection or switching event occurs between the video graphics switcher and a display device, the characteristic information is communicated to an appropriate host by triggering a connection/disconnection event with the host.Type: GrantFiled: June 29, 2012Date of Patent: May 13, 2014Assignee: RGB SpectrumInventors: Don Day, David Haycock

Patent number: 4782392Abstract: An apparatus and method for generating a rotating clock video wipe from two voltage ramps. The voltage ramps are rotated according to rotation data supplied by a controller. The rotated ramps are combined and fed to an output signal generator and then a video mixer.Type: GrantFiled: November 12, 1986Date of Patent: November 1, 1988Assignee: Ampex CorporationInventors: David A. Haycock, Jay L. Flora

Patent number: 4675905Abstract: A silent audio switch provides switching between multiple audio sources while eliminating the "pop" caused by switching spikes. Two internal buses are used for each visible external bus, whereby a new audio signal is first switched to an off-air bus opposite an on-air bus, any switching spike is allowed to subside, and then a fast mix is made between the two buses to derive the new audio signal as the switch output signal.Type: GrantFiled: April 12, 1985Date of Patent: June 23, 1987Assignee: Ampex CorporationInventors: Jay L. Flora, David A. Haycock

Patent number: 4663544Abstract: An analog gate configuration employing multiple input transistors, eliminates distortion in its output signal when switching between multiple input signals during a corresponding switch-over interval when the input transistors are sharing current, by providing circuitry for sensing the occurrence of the switch-over interval. The sensing circuitry modulates a current source during the switch-over interval to selectively increase the current to be shared by the input transistors such that the current through each input transistor is maintained constant for any transistor which contributes to the output signal.Type: GrantFiled: March 15, 1985Date of Patent: May 5, 1987Assignee: Ampex CorporationInventors: Jay L.
