Appl. No.:

11/881617

Inventors:

Thomas Paul Riederer - Santa Barbara CA, US

International Classification:

H04N 13/02

US Classification:

348 47, 348158

Abstract:

The present invention provides a stereoscopic camera containing a binocular instrument and an integrated Stereoscopic Image Acquisition Device (SIAD), and improved methods for acquiring stereoscopic image data. The invention also provides master-slave control of adjustable channels in a stereoscopic camera. The camera can be free standing and may contain integrated power supplies, image processing units, storage mechanisms, or display mechanisms. The invention circumvents the need for, and limitations of, binocular eyepieces, and is capable of producing high resolution, real-time image data while avoiding or mitigating the deleterious effects of spurious parallax, IPD, and convergence.

Appl. No.:

7/947146

Inventors:

Thomas P. Riederer - Santa Barbara CA

International Classification:

C11B 5596

US Classification:

360 7805

Abstract:

A system for the sub-micron positioning of a read/write transducer (28) of a disk drive whereby motion of the transducer, fixed to a transducer holder (30), is caused by a flexing beam (26) deflected by an input spring (32) in turn deflected by an input actuator (34). Motion of the transducer is significantly less than the deflection of the input spring, significantly increasing system resolution while decreasing positioning errors and inaccuracies. The geometry and materials of the flexing beam (26) are such as to promote bending only in a preferred plane parallel to the disk (14) and keep mechanical vibration resonant frequencies higher than the disk rotational frequency.

Abstract:

A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and/or rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and/or rotational forces imparted by the operator.
