Abstract: A  thermally-protected display  of  the  present invention includes a display panel, a cover panel, a manifold and a blower mechanism.  The display panel has a front panel surface and a rear panel surface and supports at least one signal element on the front panel surface.   The cover panel is disposed in a spaced-apart relationship forwardly of the front panel surface of the display panel to form a plenum chamber therebetween.  The manifold is in fluid communication with the plenum chamber.  The blower mechanism is in fluid communication with the manifold and is operative to supply an airflow to the plenum chamber.   The airflow enters an air inlet disposed at one end of the display panel and into the plenum chamber so that the airflow moves across the display panel and the signal element between the front panel surface and the cover panel thereby anticipating heat therefrom before the airflow exits the plenum chamber through an exhaust outlet disposed at an opposite end of the display panel.   The thermally-protected display includes a housing structure which is operative to mount the manifold and the display panel to form an enclosure having an interior whereby the rear surface of the display panel  faces the interior.   The thermally-protected display can include a plurality of display panels arranged in a series of rows and columns and the manifold forms a frame surrounding each row of display panels.

Abstract: An output buffer circuit is provided, which enables to reduce the delay of a digital output signal with respect to  an  input  digital  signal.  The  output  buffer  circuit includes  first and second FETs serially connected to each other.  A gate of the  first  FET  is  applied with a  first digital input signal. A gate of the second FET is applied with a second digital input signal. The first and second FETs operate to be opposite or complementary in logic state to each other.  A digital output signal is  taken out  from a connection point of the first and second FETs. The circuit further includes a current source for causing a bias current having the same direction or polarity as that of a drain current of the first FET to flow through the first FET in the pseudo-OFF state. A turn-on speed of the first FET from the pseudo-OFF state to the ON state is enhanced by the bias current.

Granted: 2003-09-02
Abstract: A method is provided for detecting degraded water main pipes by monitoring sonic and ultrasonic waves (110, 112, 114) and observing the characteristics of those waves. Water main pipes (30) have coiled tensioned steel wire (42) which holds the surrounding concrete (32) in compression. When corroded by water, the steel wire (73) ruptures, relieving compression in the concrete adjacent the rupture. The waves traversing the concrete of pipes have different characteristics for pipes in poor condition as compared to pipes in good condition. The sound waves in pipe in poor condition travel slower with shear waves having less amplitude and reflections occuring at later times.  Frequency domain characteristics of pipes in poor condition differ from the frequency domain characteristics of pipes in good condition. For pipes in poor condition, resonance occurs at lower frequencies and a drum head effect is apparent.
