Abstract: A pile is installed in a drilled hole in the ground by inserting a tube extending to the bottom and providing on the bottom end of the tube a bottom shoe for compressing material at the bottom of the hole. A drive tool attached to the upper end of the tube applies downward compression and reciprocating rotation forces to the tube. A hammer by-passes the drive tool to apply impact forces to an upper surface of the shoe at the bottom of the tube acting to drive the shoe in downward movement so that the shoe slides downwardly relative to the tube. A radial surface of the shoe causes compressive forces on the material at the bottom of the hole and blades on the radial surface when reciprocated back and forth by the tube cause break up of the compressed material to allow repeated compression and significantly increased supported loads on a pile which is applied with the tube removed and is supported on the shoe.

Abstract: A method and system of intrusion detection system for a multimode fiber optic cable. A light signal is launched into the cable fiber to establish a narrow spectral width, under-filled non-uniform mode field power distribution in the cable. A small portion of the higher order signal modes arriving at the remote end of the cable is sampled by use of a coupler and monitored for transient changes in the mode field power distribution. The power distribution changes with physical disturbance of the cable. When those changes are detected as being characteristic of fiber intrusion, the system activates an alarm. This method can sense and alarm any attempt to access the optical fibers in a fiber optic communication cable. In preferred embodiments, the active signal of a multimode optical fiber is monitored for both signal degradation and transient power disturbance patterns that could indicate fiber damage or physical intrusion.

Abstract: The present invention provides a method to improve the frequency resolution and phase noise of a synthesized RF signal. It also results in the superior characteristics of instantaneous frequency changeability, wide frequency setting ability, and fully digital ASIC implementation ability. The synthesized RF signal is generated from a higher reference frequency using a variable pulse stretching technique. The amount of the pulse stretch in each cycle is controlled by a phase increment value and is implemented using programmable delay lines. Pulse stretching is extended beyond one cycle by pulse swallowing, allowing the generation of an RF signal from DC up to the input reference clock signal frequency.
