Abstract: A nerve stimulation biopsy device configured to deliver a precise and adjustable stimulus signal into a biopsy site. The stimulus signal is used to distinguish between functioning nerve fibers and target tissue. Also disclosed is a method for safely performing a biopsy procedure on a biopsy site of a patient, which utilizes introducing a stimulus signal to the biopsy site.

Abstract: The present invention comprise a flag illumination assembly that both (i) illuminates an associated flag from a vertical edge of the flag and (ii) swivels with the edge of the flag as the flag is tossed in the wind. The foregoing facilitates illumination of the flag regardless of the direction of the wind. Further, a simmering effect is often created as a result of natural undulations of the flag in wind relative to the beams of light being directed thereon from the illumination assembly.

Abstract: A battery receptacle for receiving a plurality of batteries for providing a direct current to an electrical device is disclosed. The battery receptacle has a plurality of battery slots each defined by a positive terminal end wall, a negative terminal end wall, and a battery support surface between each positive terminal end wall and each negative terminal end wall. Each positive terminal end wall supports a positive lead for engagement with a positive terminal of each of the plurality of batteries, and each negative terminal end wall supports a negative lead for engagement with a negative terminal of each of the plurality of batteries.

Abstract: A system for updating clocks required to keep very accurate time. A first clock receives infrared time correction from a second clock serving as a calibration device. The first clock, upon receipt of the infrared time correction, can then send a signal—audible, visual, or an infrared signal to confirm that the time correction has been received.

Abstract: A non-destructive method for testing sealed packages for leakage, particularly packages having a gas-permeable portion and a non-gas-permeable portion, by applying a temporary barrier over the gas-permeable portion, wherein the temporary barrier has two apertures, and enclosing the package in a testing chamber having a carrier gas flowing through it to a detector, and passing a tracer gas through the package interior via the two apertures in the temporary barrier.
