Abstract: A device capable of pulling an object (e.g., a person) by or up a tensioning member (e.g., a rope) is provided. The device can be configured to mate to any location of the tensioning member, and subsequently interface with a rotational power source (such a mechanical drill). Once interfaced, an output of the rotational energy source can be rotationally coupled to a rotating drum of the device wherein the drum is in communication with the tensioning member. With the addition of power, the drum(s) can pull the tensioning member through the device and allow for a continuous force to be applied to an object attached to the device or attached to the tensioning member. The use of such a convenient and low-cost power source allows for an economic, portable, and simple to use device capable of lifting and/or pulling heavy loads.

Abstract: A brain implant system consistent with embodiments of the present invention includes an electrode array having a plurality of electrodes for sensing neuron signals. A method for manufacturing the electrode array includes machining a piece of an electrically conductive substance to create a plurality of electrodes extending from a base member. Each electrode also has a corresponding base section. A nonconductive layer is provided around at least a portion of the base section of each electrode to support the plurality of electrodes. The base section of the electrodes are then cut to separate the base member from the plurality of electrodes supported by the nonconductive support layer. The present invention also includes a complete brain implant system using the above electrode array.

Abstract: A device for pulling an elongate member includes a powered rotational motor having an output and a rotating drum connected to the output of said rotational motor where the rotating drum has a longitudinal axis and a circumference. The device further includes a guide mechanism for guiding the resilient elongate element onto, around at least a portion of the circumference of, and off of, the rotating drum. When the powered rotational motor turns the rotating drum, the rotating drum thereby continuously pulls the resilient elongate element through the device.
