Abstract: An apparatus and method for measuring ballistics in a firearm is disclosed. The apparatus comprises (a) a device for measuring pressure in a firearm-firing-chamber disposed at least in part at the strain sensitive region, and for producing analog signals indicative of the pressure, and connected to digitizing circuits which record the amplitudes of the signals representing pressure as a function of time; (b) a plurality of muzzle bullet sensors for measuring the relative times at which the bullet passes the plane of each sensor and for producing analog signals indicative of these times, the analog signals being converted to digital signals and connected to digital timing circuits; and (c) an acoustic target located downrange and including (i) sensors arrayed at corners of a triangle for sensing acoustic energy emitted by a passing bullet and (ii) a device for generating analog signals representative of the acoustic energy sensed at the triangle corners.

Abstract: A method for detecting a glycoprotein using a solid support is disclosed where the glycoprotein is oxidized by periodate, polyacrylic polyhydrazide which is a copolymer having repeating units possessing a hydrazide group and repeating units possessing hydroxyl groups is coupled to the oxidized glycoprotein and a glycoenzyme or radioactive compound containing aldehyde groups or activated ketone groups is coupled to the polyacrylic polyhydrazide which allows for detection of the glycoprotein. The glycoprotein may be directly attached to the solid support or may be bound to an antigen which is immobilized on the solid support.

Abstract: An assembly for supporting and storing an intravenous supply tube and coupling device having a septum includes an elliptical body capable of having the tubing wound thereon and first and second flanges extending radially outwardly from the body. Each flange includes one or more slots for removably receiving the tubing and securing the tubing in place. The assembly is able to hold the tubing and coupling in place while a hypodermic needle is inserted into the coupling to shield the operator's hand to thereby reduce the risk of injury to the operator. In further embodiments two or more assemblies are coupled together in a ganged fashion.

Abstract: A method and apparatus for passively determining the depth of an anomaly using means for monitoring a broad spectrum of frequencies and analyzing the amplitude and modulation of a time and/or location varying signal within discrete bands of frequencies to determine the depth of a spatial or temporal anomaly. A means for recording and mapping substerranean features based on an ascending or descending sequence of frequency measurements is also disclosed.
