Title: Method and apparatus for producing perception of high quality grayscale shading on digitally commanded displays.
Inventor: BASSETTI CHESTER FLOYD JR
IPC: G06T15/80
Filed: 1990-04-06
Abstract: The perception of grayscale shading on a digitally commanded display is produced by commanding pixels of the display with brightness-setting signals of differing average duty cycles. Brightness-setting signals having one brightness level associated with them are phase shifted in relation to time and distributed to spaced apart pixel locations at which the one brightness level is to be produced. The energization of spatially adjacent pixels is scattered in time and pixels which are energized at the same time are selected to be spatially scattered so as to avoid the perception of visual disturbances such as flickering and surface streaming.

Abstract: To produce a high-temperature superconductor of the composition Bi(2+a)(Sr(1-b)Cab)(3-a)Cu(2+c)O(8+x), where a is from 0 to 0.3, b is from 0.1 to 0.9 and c is from 0 to 2, and x has a value which depends on the oxidation state of the metals contained, oxides and/or carbonates of bismuth, strontium, calcium and copper are thoroughly mixed. In this process, the copper compound is used as a mixture of copper(I) oxide and copper(II) oxide. Then the mixture of oxides and/or carbonates is first allowed to react mutually in an inert gas atmosphere at temperatures from 700 DEG  to 800 DEG  C. for 0.5 to 36 hours before subsequently treating the mixture in an oxygen-containing atmosphere at temperatures from 700 DEG  to 875 DEG C. for 3 to 60 hours.

Abstract: A light weight, efficient, and compact piezoelectric rotary union system is provided for joining structures such as space station modules. The system comprises piezoelectric actuators attached to a first structure that engage and rotate a ring attached to a second structure. The actuators position and rotate the ring by non-sliding, smooth walking motion that provides high mechanical efficiency, long life, and negligible electrical noise. Electrical conductors embedded in the ring and the actuator traction surfaces transmit electric currents and signals between the structures. Moderate traction pressure and large contact area substantially eliminate contact heating and associated vacuum welding. The piezoelectric actuators generate relatively large translational forces at relatively low speeds. The absence of conventional rolling bearings eases connection and disconnection of the rotary union. Piezoelectric actuators with integral sensors can control the shape and stress of a relatively light and flexible ring, and can actively reduce or cancel structural vibrations.

Abstract: The percentage water content by volume in a petroleum stream is determined. A source (3) supplies microwave energy at two frequencies. An antenna (12) transmits a selected supply into the stream (17) and receives test energy either by reflection or transmission. A detector (32) provides a test energy intensity signal, difference means (9,34,40,44) provides a signal representative of the phase difference between the supplied and the test energy, and a sensor (52) provides a signal representative of the temperature of the stream. An indicator (50) determines the water percentage in accordance with the intensity, phase difference and temperature signals. The use of two frequencies for measurement in turn provides two phase difference signals to permit resolution of any ambiguity for high dielectric streams or for large diameter pipelines where the difference may be the correct phase shift plus a multiple of 360°.
