Abstract: A system and method for controlling a prosthetic limb are provided. A sensor component receives input from a wearer's muscle and provides a signal to a control component. The sensor component may be a force sensing resistor placed inside a socket of a prosthetic limb between a residual limb and the hard side of the socket. The control component processes the signal and provides instructions to an actuation component. In this manner, an actuation component may move a joint, or may change the velocity of a joint, or may change other characteristics of the prosthetic limb.

Abstract: A microreactor (10) for investigation of material reactions and properties includes a core body (12) defining a chamber (22) adapted to contain one or more sample materials and having a fluid passageway (52) from the chamber to the exterior of the core body. The chamber is in fluid communication with an external manifold (50) whereby gases, liquids or fluids can be injected and their activities can be controlled externally from ambient conditions to 400 degrees Celsius and 4,500 psi. Transparent windows (30a, 30b) in the core body permit continuous visual access to the chamber, allow direct probe beam interaction with sample during a reaction or observation, and external detection of the probe beam to investigate in situ reaction processes.

Abstract: A tool for the rotation of sockets, screws, nuts, or other fasteners or the like and a method for securing a fastener are provided. The tool may have a body having an interior area wherein the interior area has walls which are parallel and have sections having different widths between the sections. Further, the tool may have a first portion which may have widths sized to receive fasteners based on, for example, a metric system. A second portion may have widths sized to receive fasteners based on, for example, English units of measurement. The tool may be placed around a fastener wherein the fastener contacts sections which are separated by a width sufficient to fit around the fastener. The tool may then be rotated to secure or remove the fastener.

Abstract: This invention discloses a method of using galactose-binding lectins, such as Ricinus communis agglutinin I (RCA.sub.I), to kill cancer cells. RCA.sub.I has been found to severely weaken certain types of cancer cells, such as bladder carcinoma. This weakening can kill substantial numbers of cancer cells. In addition, it is possible to attach RCA.sub.I to other substances which impose stress on cells, such as cytotoxic drugs or enzymes that catalyze exothermic reactions, which can kill weakened cancer cells.

Abstract: An improved method for assaying for cancer by detecting .beta.-linked galactose moieties associated with cells is disclosed wherein a label specific for such moieties is added to the cells and subsequently sensed.

Abstract: An enzymatic noninvasive method for detecting cancer in mammalian tissue is disclosed. This method comprises incubating exfoliated cells from mammalian tissue suspected of containing cancerous cells, and assaying them for galactosyl transferase activity. The level of galactosyl transferase activity has been found to be significantly altered in cells from cancerous tissue as compared to the level in cells from normal tissue.
