A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

A system, method, and apparatus for ultrasonic detection of flaws or defects in oil field tubulars utilizing composite transducers.

The use of the composite transducers allow for a greater inspection area over traditional transducers thereby reducing the number of channels needed for inspection of the tubulars.

Provided is an inverted pendulum mobile vehicle such as a single-passenger coaxial two-wheel vehicle which is capable of turning with a small turning radius without causing discomfort to a rider or a vehicle occupant or causing a cargo or the like on the vehicle from shifting or falling off from the vehicle. The vehicle comprises a wheel supporting frame (12), a body frame (12) supported by the wheel supporting frame so as to be rotatable around a vertical axial line and carry a rider and or a cargo and a body coupler (52, 78, 70) that couples the body frame relative to the wheel supporting frame in a prescribed dynamic positional relationship. Thereby, even when the wheel supporting frame undergoes a rapid yaw movement either while traveling in a fore-and-aft direction or remaining stationary, the body frame that carries a vehicle occupant or a cargo is allowed to follow the yaw movement of the wheel supporting frame at a slower angular speed and / or acceleration / deceleration so that the vehicle occupant is prevented from experiencing discomfort and the cargo is prevented from shifting on the body frame or falling off from the vehicle.

A flex circuit having conductive traces formed on only one side of a base film for attaching to both sides of a DITO touch sensor panel is disclosed. By having conductive traces formed on only one side of the base film, the number of process steps and fabrication cost can be reduced because only a single etching step is needed. Furthermore, because the flex circuit is thinner, the resultant space savings can be utilized for other features in a device without enlarging the overall device package.
