Abstract: A control apparatus for controlling one or more functions of a controlled device includes a movement sensor operable to detect both a direction of movement and an amount of movement of the control apparatus, a microcontroller for receiving a signal corresponding to the direction and amount of movement and generating one or more corresponding control signals for controlling the controlled device, and a transmitter for transmitting the control signals to the controlled device. The control apparatus may include a position selectable control and a sensor coupled to the control to sense a position thereof. According to some implementations, the movement sensor may be used to control a direction of the controlled device, and the position selectable control may be used to control a speed of the controlled device.

Abstract: A system for detecting precursor seismic electromagnetic waveforms.

Abstract: A method of detecting precursor seismic electromagnetic waveforms and predicting future seismic activity in the form of an earthquake by placing a detector including a dielectric material in contact with the earth. The detector receives at the dielectric material precursor seismic electromagnetic waveforms traveling within the earth emanating from a region of seismic activity. A sensor responsive to the dielectric material senses a series of individual discrete signals imposed by the waveforms at the dielectric material wherein each of the signals has the characteristic of a rise time that is shorter than its fall time. Alternatively, the discrete signals may be a single discrete signal characterized by a plurality of overlapping waveforms. Then predicting based on the series of the signals the occurrence of the earthquake.

Abstract: A method of wetting and coating various metals, which have been mechanically polished and chemically cleaned and etched, includes plasma cleaning and etching the metal and delivering mercury or other liquid metals through the plasma to the surface of the metal to be wetted. Tungsten, molybdenum, steels and elkonite are among the metals which may be wetted with a liquid metal according to the method of this invention. Molybdenum is cleaned and etched in a solution of 2-propanol and H.sub.2 O.sub.2.
