Patent number: 10298846Abstract: A method for adjusting a pointing angle of an actively stabilized camera is provided. The camera is housed by an active stabilization system configured to stabilize the camera in accordance with a commanded pointing angle. The active stabilization system comprises a steering member rotatable around one or more of a pan axis, tilt axis, and roll axis of the system. The method comprises: deriving a joint angle measurement of the steering member associated with a rotational movement of the steering member and adjusting the pointing angle of the camera, based on the derived joint angle measurement, in a direction of the rotational movement of the steering member, if the joint angle measurement exceeds the threshold window. If the joint angle measurement is within the threshold window, the pointing angle of the camera is actively stabilized in accordance with the commanded pointing angle.Type: GrantFiled: March 14, 2014Date of Patent: May 21, 2019Assignee: FREEFLY SYSTEMS, INC.Inventors: Steve Webb, John Ellison, Tabb Firchau, David Bloomfield

Patent number: 9574703Abstract: A stabilization system or gimbal having a mounting arrangement (3) for a camera providing for rotation about pan, roll, and tilt axes (210, 230, 220) where tilt and roll axis (220, 230) position can be independently adjusted is described. The arrangement can be configured so that when adjusting the stabilization frame relative to the roll axis, adjustment of the camera COG relative to the tilt axis is inhibited. The system can further be arranged such that when adjusting the roll axis, adjustment relative to the tilt axis is inhibited. Similarly, when adjusting the pan axis, adjustment to the tilt or roll axes may be inhibited.Type: GrantFiled: August 15, 2014Date of Patent: February 21, 2017Assignee: FREEFLY SYSTEMS, INC.Inventors: Tabb Firchau, David Bloomfield, Shane Colton, Ian Roper

Publication number: 20140267778Abstract: Apparatuses and methods for controlling a gimbal and other displacement systems are disclosed herein. In accordance with one or more embodiments of the invention, a pointing angle of a camera attached to a gimbal may be controlled based, at least in part, on one or more control signals provided by a controller. The control signals may be used to compensate for displacement of the camera, to add perceived displacement of the camera, to selectively align a pointing angle of the camera and/or to allow a pointing angle to be manually determined.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: FREEFLY SYSTEMS, INC.Inventors: STEVE WEBB, JOHN ELLISON, TABB FIRCHAU, DAVID BLOOMFIELD

Publication number: 20130026689Abstract: An adjustable vibration reduction device is provided to dampen and reduce vibration in order to maintain performance of equipment attached to a system. The vibration reduction device includes at least one resilient vibration dampener coupling an upper assembly to a lower assembly. The upper assembly is attached to an equipment mount frame via a pair of stop members extending through a pair of stop apertures in the lower assembly to control movement of the lower assembly relative to the upper assembly. The lower assembly is attached to a structure frame via a pair of fastening devices. The vibration reduction device may be adjusted by selectively including at least one resilient vibration dampener, such as an o-ring, having predetermined characteristics to maximize vibration reduction or isolation. A plurality of vibration reduction devices are provided in a system that causes or transfers vibration, such as a vehicle, having electronic equipment attached thereto.Type: ApplicationFiled: July 20, 2012Publication date: January 31, 2013Applicant: FREEFLY SYSTEMS INC.Inventors: David Bloomfield, Tabb Firchau

Publication number: 20080003466Abstract: Method and apparatus for steam reforming a sulfur-containing hydrocarbon fuel, such as a diesel hydrocarbon fuel. The apparatus includes a desulphurization unit, a pre-reformer, and a steam reforming unit. A carbon dioxide fixing material is present in the steam reforming catalyst bed to fix carbon dioxide that is produced by the reforming reaction. The carbon dioxide fixing material is an alkaline earth oxide, a doped alkaline earth oxide or a mixture thereof. The fixing of carbon dioxide within the steam reforming catalyst bed creates an equilibrium shift in the steam reforming reaction to produce more hydrogen and less carbon monoxide. Carbon dioxide fixed in the catalyst bed can be released by heating the carbon dioxide fixing material or catalyst bed to a temperature in excess of the steam reforming temperature. Fuel processors having multiple catalyst beds and methods and apparatus for generating electricity utilizing such fuel processors in conjunction with a fuel cell are also disclosed.Type: ApplicationFiled: September 7, 2007Publication date: January 3, 2008Applicant: Texaco Inc.Inventors: James Stevens, David Bloomfield
