Title: Gray scale value compensation arrangement for image sensor
Inventor: SU WEI-MING
IPC: H04N1/401
Filed: 1997-10-09
Abstract: The arrangement includes a power supply (R1,.., R9) for providing several different voltage levels, and an analog multiplexer (30) controlled through a digital signal (S2, S1, S0), for outputting one of the different voltage levels. An image sensor (32) scans an image pixel and outputs an image voltage of the pixel, and an A/D converter (34) receives the voltage output by the analog multiplexer as a peak voltage and the voltage output by the image sensor as an analog input, and outputs an original gray-scale value of the pixel. A microprocessor (36) detects the maximum white level value in a number of original gray-scale values of a series of white pixels along an x-coordinate axis, to set the digital signal for the control of the analog multiplexer, so that it outputs the nearest voltage as its output voltage. The microprocessor calculates then an average white level value for a number of gray-scale values of corresponding white pixels in y-axis direction, and calculates a compensated gray-scale value of the pixel corresponding to the original gray-scale value.

Title: Method for generating rotational movement from solar energy
Inventor: SCHATZ JUERGEN
IPC: F03D1/04
Filed: 1997-10-29
Abstract: The torque-creating process involves converting parallel flow into rotary flows to act on a rotor.  When the rotor (8) is braked and yields energy, the oncoming masses flowing onto the rotor blades (12) are divided into part flows.

Title: Determining absolute positions for stroke determining cylinder and direction relative to stroke
Inventor: YANG SOON YONG
IPC: G01D5/14
Filed: 1998-01-14
Abstract: The position determination method is carried out using a piston rod (400) with protruding and recessed parts at predetermined distance from both ends, which form a magnetic scale to produce signals. The magnetic scale is formed with a predetermined formation cycle. A magnetic scale determination stage is used to obtain several sine voltages (S200), which have different phases, using a magnetic sensor unit according to a drive condition of the cylinder (S100). An oscillation production stage (S300) converts the sine voltage, obtained in the magnetic scale stage, into a square wave oscillation, and produces a triangular oscillation, which has the same cycles as the unconverted square oscillation. A first absolute position value determination and stroke direction detection stage determines a first absolute value and the movement direction of the cylinder in relation to the stroke using a pair of square and square oscillations, produced in the oscillation stage. A second absolute position value computing and storage stage computes and stores a second absolute value, which has a predetermined value on the basis of the first absolute position value.
