Abstract: A cable driven actuator and actuator method involve a movable link that is movable about a path by a cable connected to the link, and a movable support member having a cable routing element. The support member is movable in a manner to change a moment arm of the cable acting on the link to control torque applied to the joint.

Abstract: A pneumatic compressor capable of supplying compressed gas to a pneumatic tool. The compressor can be powered alternatively by either a battery or an AC power source. The compressor comprises a permanent magnet DC electric motor and circuitry for converting the AC power source to DC power. The compressor includes a receptacle for accommodating one or more of a plurality of batteries and includes circuitry for using batteries having different voltages. The AC power source may also be used to charge a battery connected to the compressor.

Abstract: The present invention is directed to an assembly for providing ergonomic grasping for a category of tool users. The assembly may be sized for ergonomic grasping by the hand of a user belonging to a category, such as large, medium, or small. The assembly includes a generally flat surface and a surface generally shaped for reception in a user's palm. The assembly of the present invention may be employed with a power tool or pneumatic tool, such as a hand held tool. A securing extension for securing the base to a tool is mounted on the generally flat surface.

Abstract: The present invention is directed to a wireless electrical control system for power tool and specifically to a wireless control device for a router. The electrical control system may include a handle suitable for manipulating a router. A switch and a wireless transmitter are disposed in the handle. Communicatively coupled to the transmitter is a wireless receiver capable of receiving the transmissions from the transmitter in the handle. In alternative embodiments the wireless receiver is disposed in the router itself or the receiver is disposed in an outlet unit, which is capable of electrically coupling to the router's electrical cord and an electrical outlet. The wireless receiver of the present invention is capable of controlling the flow of electricity to the electrical system of the router so that the router is capable of being altered from the switch mounted on the handle, thus allowing users to change the power setting while retaining secure control of the router.

Abstract: A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s). Wheel modules are independently powered to both rotate and steer, and, responsive to the control unit, are capable of rolling the exercise device in a direction of travel intended by the patient.
