Each pod has two associated, non-parallel, elastic struts. A first end of each strut is attached to the supporting base and a second end of each strut is attached to the payload at a respective mounting point, and the a projected elastic center of the system is substantially co-located with said center of mass. The vibration isolator system is operable to substantially prevent translational vibration of the supporting base from inducing angular rotation of the payload.Type: GrantFiled: March 9, 2009Date of Patent: May 31, 2011Assignee: DRS RSTA, Inc.Inventors: David Hiley, Reynaldo Cabrera, Jason Brennan

Publication number: 20110089308Abstract: In order to control vibrations of two parts of a piece of machinery, a variable force may be generated to oppose the vibrations, with the variable force being generated under control of a controller on the basis of an iterative relationship, the iterative relationship being such as to generate the force of one iteration using a controller output signal in frequency domain vector form derived from the controller output signal of the immediately previous iteration in frequency domain vector form plus a frequency domain vector quantity derived from the resultant vibration of more than one previous iteration. Where these two parts are connected by multiple (f) mounting devices, the controller output signals a previous iterations are taken into account, and the frequency domain vector quantity derived from the controller output signals and more than f previous iterations.Type: ApplicationFiled: December 20, 2010Publication date: April 21, 2011Inventor: Peter Michael Trewhella Fursdon

Patent number: 7905463Abstract: A multi-axis gimbal has each axis defined by a respective spherical shell driven by a flat, compact motor attached to the driven shell and to a next outer shell (or to an external mounting platform, in the case of the outermost shell). The shells rotate about respective axes. In one configuration, the outermost shell is referred to as the “azimuth” shell because in use it rotates about a vertical axis. The next inner shell is an elevation shell that rotates about a first horizontal axis that is orthogonal to the axis of the camera or other sensor payload. An optional third shell can be used to provide “roll” motion, such as rotating a camera about its axis to obtain a particular rotational orientation with respect to a target.Type: GrantFiled: December 13, 2005Date of Patent: March 15, 2011Assignee: Optical Alchemy, Inc.Inventors: Heidi Burnham, Marc Daigle

Publication number: 20100320357Abstract: An apparatus has an active suspension including an electromagnetic actuator coupled to a plant in a vehicle. A force bias eliminator is coupled to the plant for causing the actuator to experience a zero-mean load, and a vibration isolation block generates a control signal based on the response of a nominal plant to measured disturbances of the actively suspended plant. A compensation system modifies the control signal in response to a difference between the response of the nominal plant to the control signal and a measured response of the actively-suspended plant to the control signal.Type: ApplicationFiled: September 2, 2010Publication date: December 23, 2010Inventors: Upendra V. Ummethala, James A. Parison, Thomas C. Schroeder, Daniel Francis Opila, Linda Ystueta, Roman Litovsky
