Abstract: A system for monitoring organ health during treatment for cancer and the like makes use of physiological imaging of the kind used for treatment monitoring and organ-specific processing to provide a comprehensive assessment of treatment side-effects.

Abstract: A safety device for tackers includes a safety slide slidably connected to the outlet of the tacker and the safety slide has a stop protruding from the inside thereof. The rod has one end contacts the stop and the other end of the rod has a plastic tip connected thereto. An ignition spring is connected between the plastic tip and a safety switch. A recovery spring is connected to another position of the rod to position the rod. The safety slide is slidably connected to grooves of the tacker. When the safety slide contacts against an object to be stapled, the rod is pushed by the stop and activates the ignition spring to activate the safety switch so as to reduce the impact of the rod and the safety switch.

Abstract: A fastening tool includes a contact arm system for actuating an electrical switch, the contact arm system including an elongated member having a tool alignment slide disposed at one end, and a coil spring at the other. When the fastening tool is pressed against a work surface, the tool alignment slide moves the elongated member toward the electrical switch so that the coil spring causes a switch operator to close the switch. The fastening tool also includes a fastener guide system which pivots two parallel guide fingers simultaneously into the drive path of the fastener driver, so that one or both guide fingers may engage respective legs of three different kinds of staples, as well as brads and headless pins. The contact arm and fastener guide systems are compact and ideal for use in the space-sensitive environments of, for example, a tacker and a hand stapler.
