摘要:
Systems and methods for providing a haptic manipulandum are described. In one described system, a lever arm is pivotably coupled to a housing, and configured to apply a processor-controlled force to a substantially-spherical manipulandum to provide a haptic effect. The described system may include a processor in communication with an actuator for providing the haptic effect.

An apparatus for manufacture of a tire, the apparatus including a drum with shoulder having a generally cylindrical main receiving surface to receive the products to be assembled, the main receiving surface being radially retractable. The drum has a shoulder axially to the side edges of said main receiving surface. The drum is mounted on a shaft. At least one associated axially movable side crown is mounted coaxially with the drum. The drum has a lateral protuberance coaxially juxtaposed to at least one of its shoulders. The side crown is axially slidable at least partly under the lateral protuberance, the lateral protuberance forming a quasi-cylindrical support surface whose outside diameter is smaller than the diameter of the main receiving surface. The side crown has a substantially cylindrical outer surface capable of passing axially outside of the lateral protuberance.

A tube connecting device comprises a housing, a socket formed in the housing for receipt of a pipe to be releasably secured therein and a securing arm pivotally mounted to the housing. The securing arm is pivotable from a first, locked position in which a portion of the arm projects through an associated aperture in the wall of the socket to engage a complementarily-shaped portion of the pipe to be retained, to a second unlocked position in which the projecting portion of the securing arm is withdrawn from the socket. The device further comprises an actuator mounted on the arm and a locking member located in a chamber within the arm.

A control system for a two-wheeled vehicle, including an inertial measurement unit (IMU); one or more control moment gyroscopes (CMGs); one or more CMG controllers to control the one or more CMGs; an accelerometer to measure a y-axis acceleration for the vehicle, the y-axis being perpendicular to a direction of travel of the vehicle and parallel to a ground surface; and a processing element to calculate a roll angle for the vehicle based at least in part on the y-axis acceleration measured by the accelerometer, determine a force component based at least in part on the calculated roll angle, and generate a CMG command for a CMG gimbal rate based at least in part on the determined force component.

In one embodiment of the invention, a first control signal is generated to control a robotic surgical instrument. The first control signal is then coupled into the robotic surgical instrument. In response to the first control signal, a first valve in the robotic surgical instrument is opened to flow a first fluid over a surgical site.
摘要:
A slave manipulator manipulates a medical device in response to operator manipulation of an input device through joint control systems. The stiffness and strength of the slave manipulator are adjustable according to criteria such as the mode of operation of the slave manipulator, the functional type of the medical device currently being held by the slave manipulator, and the current phase of a medical procedure being performed using the slave manipulator by changing corresponding parameters of the control system. For safety purposes, such changes are not made until it is determined that it can be done in a smooth manner without causing jerking of the medical device. Further, an excessive force warning may be provided to surgery staff when excessive forces are being commanded on the slave manipulator for more than a specified period of time.
摘要:
In one embodiment of the invention, a robotic surgical system is provided including a master control console and a surgical manipulator. The master control console generates control signals to cause one or more fluids to flow into or out of a surgical site. The surgical manipulator is coupled to the console to receive the control signals and includes at least one robotic arm and a surgical instrument coupled thereto. The surgical manipulator controls the surgical instrument in response to the control signals to control the flow of the one or more fluids into or out of the surgical site. The surgical instrument has a first robotically controlled valve that is responsive to the surgical manipulator and a hollow tube having a first end coupled to the first robotically controlled valve with an opening at a second end to direct the flow of one or more fluids.
