Patent EP-0366165-A2 (EP)
Inventor: FERNANDO GERARD MARIUS XAVIER
IPC: G06T7/20
Filed: 1989-09-01
Abstract: A method of picture motion measurement in which two pictures are correlated to determine correlation as a function of displacement to determine peak correlation values corresponding to motion vectors. In the method a maximum sample point (P) associated with a peak in a correlation surface is located and a second sample point (D) of those immediately surrounding said point (P) selected having the steepest gradient with respect to the said point (P). The difference (d1) in magnitude between these points is determined as is the corresponding difference (d2) between the said point (P) and a point (H) colinear therewith. A comparison of these differences (d1 and d2) is used to determine the location of the peak to an accuracy better than the interval between adjacent sample points.

Title: Method and apparatus for use in transferring an image

IPC: G03G13/26
Filed: 1989-05-30
Abstract: An improved method and apparatus for use in exposing of photosensitive material (24) to ultraviolet radiation (110) includes a carrier (26) which is a film strip having a photoconductive layer. The film strip is indexed along a path which extends through a linear array of stations. At a charging station (60) an electrostatic charge is applied to the photoconductive layer on the film strip. At an exposing station (46), the photoconductive layer on the film strip is exposed to a light pattern which forms a reduced size image of an original to thereby render areas of the photoconductive layer conducting. At a developing station (48), toner particles are electrically attracted to the conducting areas of the photoconductive layer on the film strip. The toner particles are fused (66) to each other and the material of the film strip to form a permanent visible image. The film strip is then indexed to an exposing station (50) where ultraviolet radiation is directed through the film strip to project an enlarged image onto photosensitive material (24). The ultraviolet radiation has an energy level of at least 500 ergs per square centimeter at the surface of the photosensitive material to initiate a photochemcial reaction in the photosensitive material so that the image of the original on the film strip is transferred to the photosensitive material.

Abstract: A current limited DC power controller is provided with an output stage (10) having a controllable solid state switching device (Q1) for conducting current between a pair of output terminals (12, 14) and a drive circuit (20) for controlling the operation of this switching device in response to a control signal. A programmable current source (30) is used to produce a reference current signal in response to a command signal and this reference current signal passes through a resistor (R2) to produce a reference voltage signal having a magnitude proportional to the command signal. When the power controller is off, the reference voltage signal is clamped to a preselected value. A second voltage signal proportional to the load current is combined with the referenced voltage signal and used to produce the control signal to which the drive circuit responds.

Abstract: A control system for an internal combustion engine (31) has an ignition timing control device (41) and a combustion duration control device such as a mixture controller (42). Sensors (36, 37) detect the start and end of combustion which are compared (44, 45) with a look-up table (35) of target values for the engine speed (33) and load (32) to provide error signals. The processed error signals (46) provide corrections which are added (39, 40) to base values from look-up tables (34) of ignition timing and mixture and supplied to the control devices (41, 42) so as to tend to eliminate the error signals, so that the engine (31) runs with its designed start of combustion and combustion duration values.

The tubular portions may be located at the margins (8, 10, 11) of the fabric piece and also at intermediate positions where the fabric piece needs to be held down, for example in a depression in the support. They may project from a surface of the fabric piece and may be like loops or they may be in the form of tubular hems or a tube lying between front and rear surfaces of a double jersey structure.

Abstract: In a liquid crystal display device (21) of the present invention, a display area, a connecting area and a remaining area can be set separately in ON (display) and OFF (non-display) states. Accordingly, even in the liquid crystal display device wherein a positive display (normally white display) is made, a negative display (normally black display) can be effected by switching the ON and OFF states. Similarly, in the liquid crystal display device wherein the negative display is made, it can be switched to the positive display. 
     Also, since the ON and OFF states of a liquid crystal layer corresponding to each of the three color filters (58) of red, green and blue can be set optionally, eight color displays are possible by combination of the three colors. Here, the segment side and common side transparent electrodes (54,55,59,60) are formed respectively in two divisions, so that the transparent electrode (54,55,59,60) can be formed by a conventional patterning technique without using the precise patterning technique.

Abstract: A video signal having a group of frames of successive dependent frames and an independent frame following the frames is coded per group of frames, by interframe and intraframe coding, and a data amount of the group is controlled by feedback and feed forward control. A quantization step number for the dependent frames is changed based on a rate of a total data amount of the group and a data amount of the dependent frames for the feedback control. A temporary quantization number of the independent frame is determined for the feed forward control. A data amount predictive value for each blocks in the independent frame is determined by an activity of an image in each blocks and the temporary number of quantization steps. The predictive value is subtracted form the total data amount. A subtraction result for each blocks is accumulated to output a positive compensation amount if the result is a positive amount and a negative compensation amount is a negative amount. The compensation amount is then added to the temporary number of quantization steps to obtain a number of quantization steps for the independent frame. The data amount of the group is thus controlled by quantizing the dependent and independent frames by the numbers of quantization steps of the dependent and independent frames, respectively.
