Abstract: The present invention is an adjustable weight dead blow hammer comprising a hollow head filled with an acceptable fill material. A handle is connected to the head wherein the handle has a hollow chamber that traversers the length of the handle and has an opening into the head. The weight of the hammer head may be adjusted by moving the fill material between the head and the hollow chamber in the handle. Adjustment may be accomplished by a corkscrew device which is disposed within the hollow chamber and having a screw tip at the opening and c screw head on an outside portion of a bottom end of the handle. The corkscrew device within the hollow chamber moves the fill material between the head and the handle. More fill material in the head increases the force of impact, and less fill material in the head decreases the force of impact.

Abstract: A method and apparatus for measuring relative hydration of a substrate. Measurements of the electrical characteristics of the substrate and the force applied to and the temperature of the substrate during the measurement provide inputs for determining such relative hydration of the substrate.

Abstract: A simple, efficient technique for encoding NTSC video signals features sampling the signal at 8/3 the subcarrier frequency, generating no more than 256K samples for a full 525 line frame, generating as many samples per horizontal scan line as there are columns in a memory where the frame is to be stored, incrementing a row address counter for the memory once for each new horizontal scan line, and providing an analog reproduction of the color burst signal directly from and based solely on the digital samples of the color burst signal.
