Power tools of the type under consideration include hammer drills, for example, which are electric or battery powered and includes two modes of operation: a rotation mode and a rotation-hammer mode. A manually operable selector lever enables the hammer drill to be selectively operated in one of the two modes by disengaging and engaging a hammer mechanism. In rotation-hammer mode, the drive shaft of the hammer drill rotates a tool element about a rotational axis and oscillates the tool element along a rotational axis. An attachment mountable within the chuck of a hammer drill prevents a tool element from rotating when the hammer drill is operating in rotation-hammer mode. The hammer drill attachment transfers hammer action, but not rotation, to the tool element. The hammer drill attachment enables dual function power tools to be operated in a hammer only mode to perform a function, for example, chiseling.

Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented.

Crossbow bowstring drawing mechanisms which are integrated into or secured in the crossbow handle and which provide a straight and balanced draw to the crossbow bowstring to cock the crossbow bowstring in position in the crossbow trigger mechanism ready for firing. The cocking system can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a crossbow. An internal or external source of rotational power, such as hand crank, power screwdriver or an electrical motor, is preferably utilized in conjunction with a claw member including a bowstring engaging portion to translate rotation of the input source to longitudinal movement of the claw member to draw or release the crossbow bowstring resulting with minimal effort being expended by the user. The claw member may include adjustable cams used to center the claw member with respect to the crossbow barrel.

The present invention describes a device for performing breast biopsies and / or therapy within magnetic resonance imaging (MRI) systems. The apparatus includes a RF receiver antenna for magnetic resonance imaging of the breast. The RF coil includes openings in the front and side to provide access to the breast during the procedure. Compression plates are integrated into the breast coil which compress the breast either laterally or in the head / feet direction as required for optimal access to the breast. The apparatus includes a mechanical device for positioning interventional instruments in the breast such as biopsy or therapy instruments. The mechanical positioning devices position the instrument along the desired trajectory to the target site and insert the instrument into the breast while the patient remains inside the MRI scanner. Real time MR images may be acquired during instrument alignment and insertion to verify the trajectory. The mechanical positioning devices allow manipulation of instruments in any type of MRI scanner, including high field MRI systems with cylindrical magnets. The positioning devices provide a means to overcome limited access to the patient in MRI scanners. The positioning devices may be manually operated by means of gears, drive shafts, cables or other mechanical means. Or they may be electronically controlled by means of MR compatible motorized drive systems. The devices may be remotely controlled from outside the magnet for MRI systems that have limited access to the patient in the magnet. An interface between the electronically controlled drivers and the MRI scanner computer can provide robotic control of the instrument.

A mirror device includes one or more light devices disposed behind a mirror, to generate lights to light the mirror.

The light device may thus be actuated to light the mirror without being contacted by the users or without being operated by the users manually. A control device may be used to actuate the light device to generate the light. The remote detecting device includes a light emitting device to generate a light to detect whether the user goes toward the mirror or not.

A transom bracket enclosing a hydraulic power cylinder is mounted to the transom of a watercraft. An actuation rod of the power cylinder moves multiple lift arms connected to a platform bracket supporting a platform for supporting a small auxiliary watercraft.
