Abstract: A method of improving automatic document feed of media printed with phase change inks coats the surface of the phase change inks on the media with fine particles. The particles may include PMMA, glass bead, silica particles, crushed glass particles, kaolin clay, micronized PE and PTFE, calcium carbonate powder, hard inks or toner powder. The particles may be applied to the surface of a transfix drum by oil transfer or electrostatically prior to jetting the phase change ink, or in the case of hard inks may be jetted onto the surface of the transfix drum (offset) with the phase change ink or onto the print media (direct) after application of the phase change ink in an overprint printing process. Also the particles may be applied by a pair of finishing rollers after the media has been printed with the phase change inks, either in a direct or offset print process, the finishing roller on the print side being coated with the fine particles.

Abstract: A system for detecting wood-destroying insects by sensing acoustic emissions generated by the insects as they feed. The system comprises two acoustic emission sensors, an amplification section, a signal processing section and an indicator section. The system comes into mechanical contact with the wood to be inspected through the use of a bolt which is inserted into the wood and attaches to an acoustic emission sensor or through the use of an adhesive layer which directly attaches an acoustic emission sensor to the wood. The acoustic emission sensors are electrically connected to the amplification section which is electrically connected to the signal processing section. The signal processing section is capable of distinguishing between insect-caused acoustic emissions and noise-caused acoustic emissions detected by the acoustic emission sensors. The results of the signal processing section are sent to the indicator section.

Abstract: The elevation angle of a low angle target is accurately measured by subtracting from the received radar signal signals derived from an estimated value of target elevation which reduces the resulting signal to a minimum. The estimated value is an accurate measure of target elevation.
