  • Patent number: 10245036
    Abstract: A surgical stapling device is configured for use in open and/or laparoscopic surgical procedures. The device includes a handle assembly, a shaft assembly coupled to the handle assembly, and an end-effector coupled to the shaft assembly. The end-effector comprises of a jaw assembly configured to clamp, staple, and/or cut a target tissue. The handle assembly comprises of a trigger member that can activate a control member to close the jaw assembly to clamp, staple, and/or cut the target tissue. The stapling device includes a safety lockout member to selective prevent the control member to close the jaw assembly to clamp, staple, and/or cut the target tissue.

  • Publication number: 20070213685
    Abstract: A method of removing an implanted vessel filter by a femoral approach comprising the steps of providing a catheter with a curved tip, inserting a straightening device into the catheter to move the catheter tip from a curved position to a more straightened position, advancing the catheter tip through the femoral vein and past a cranial end of the filter, withdrawing the straightening device to enable the catheter tip to return to the curved condition, and inserting a filter grasping device though the catheter and a curved catheter tip to exit a distal portion to grasp the filter.

  • Patent number: 5468099
    Abstract: A seam tracking robotic drilling machine (10) is disclosed which is capable of moving a drill head along the seam (12) between abutting skin panels (16, 18) to drill a plurality of precisely positioned holes (18) through the panel. The machine (10) includes a perimeter support frame (20) which mounts a platform (36) for rotation about an axis (38) generally perpendicular the panels to be drilled. The platform supports a carriage (48) for movement along an axis 50 parallel the surface of the panels and in the direction of the seam while the carriage (48) supports an inner carriage (62) for movement along axis 60 perpendicular thereto. A drill head (74) is mounted on the inner carriage (62). A series of variable height vacuum cup assemblies (22-28) support the perimeter support frame (20). A similar series of variable height vacuum cup assemblies (66-72) support the inner carriage (62).

  • Patent number: 5451188
    Abstract: A driver-controlled differential lock control system allows vehicles with automatic, electronic and single range manual transmissions and air pressure actuated differential locking devices to have the vehicle differential thereof locked on only at low speeds. The control system includes a vehicle speed sensor, such as a speedometer transmitter, and a speed switch responsive to the vehicle speed sensor to selectively actuate a normally-closed air solenoid valve disposed in a vehicle air supply line upstream of a manually controlled air valve which supplies the differential lock actuator. The speed switch normally supplies power to the air solenoid valve until the speed of the vehicle exceeds a predefined limit whereat power is discontinued to the air solenoid valve causing disengagement of the differential lock.

  • Patent number: 5365436
    Abstract: An electronic data link that services components of the vehicle including components other than the engine and an electronic engine management system that services the engine operate in different data formats and are interfaced by a special electronic module that provides translation services for accomplishing bi-directional through-transmission of data between them. The module has programmable memory with different levels of security and can detect the absence of a vehicle speed sensor at incipient vehicle launch. The speed sensor serves both the data link and the electronic engine management system through the special module.

  • Patent number: 5321980
    Abstract: An integrated throttle position validation sensor includes electrically independent throttle position and position validation components responsive to a single mechanical input applied to a protective sensor housing. By suitable mounting to the throttle control device, the mechanical input corresponds to accelerator pedal position. Within the sensor housing a potentiometer moves with the mechanical input whereby a variable voltage throttle position signal is generated. Also, within the housing a separate validation switch responsive to the mechanical input provides an independent representation of throttle control device position in the form of, for example, a bi-state validation signal. The sensor integrates previous separate throttle control position and position validation functions into a single environmentally secure housing which requires no calibration. The integrated sensor is more reliable and less costly than previously available separate throttle control and idle validation functions.

  • Patent number: 5133321
    Abstract: An integrated throttle control and idle validation sensor includes mechanically coupled but electrically independent throttle control and idle validation components. A single mechanical input to the protective sensor housing corresponds to an accelerator pedal position and causes selective coupling of a supply voltage to one of an idle validation conductor and a throttle validation conductor for interpretation by an electronic control system. The throttle control system within the sensor housing comprises a potentiometer adapted for movement corresponding to the mechanical input whereby a variable voltage throttle control signal may be delivered to the electronic fuel control system. The sensor integrates previous separate throttle control and idle validation functions into a single environmentally secure housing and requires no calibration. The disclosed throttle system is more reliable and less costly than previously available separate throttle control and idle validation functions.
