摘要:
A light source for a scrolling color illumination system includes a lamp (212) producing light, first and second independent reflectors (220, 230) each receiving a portion of the light from the lamp (212), and a light guide (260) receiving two independent images of the light source created by the portions of the light received by the first and second independent reflectors (220, 230). Through such an arrangement, the light guide (260) provides a light beam at an output thereof having an aspect ratio that is twice an aspect ratio of the light beam produced by the lamp (212) while preserving its original etendue. Beneficially, a polarizing element (266) polarizes the unpolarized light beam from the light guide (260) and, in the process, the aspect ratio is further doubled, again without an increase in the etendue.

A color projection video system utilizing only a single light valve. A white light source is separated into into red, green and blue bands. Scanning optics cause the RGB bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of panels on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. The device includes circuitry to synchronize the illumination of the light valve with the video signal and to minimize video breakup when changing video sources.

A procedure for the control of ratio-change occurrences of an automatic transmission in a motor vehicle, which vehicle possesses a hydraulic system with at least two hydraulic pressure branches (3, 9) with different hydraulic pressures, wherein in a first hydraulic pressure branch (3) controllable pressure reducing valves (4, 5) can be found, by which the hydraulic users (S1, S2) can be supplied with an activation pressure, wherein in the first hydraulic pressure branch (3), a pressure regulation valve (6) is placed, the exit port of which is connected to a line of the second hydraulic pressure branch (9), and wherein by the activation of the pressure regulation valve (6) the pressure in the first hydraulic circuit (3) is adjustable, and whereby in the first hydraulic pressure branch (3) a hydraulic pressure is provided, which represents the highest, necessary operational pressure of the hydraulic users (S1, S2, 11) plus an offset pressure. Further, provision is made that in certain operational conditions of the motor vehicle, one of the pressure reducing valves (4, 5) of, respectively, one of the two ratio-changing organs (S1, S2) remains fully open and the offset-pressure becomes reduced to the value of zero, or to nearly zero, and upon the removal of said certain operational condition the off-set pressure is once again increased and the pressure reducing valve (5) resumes its function of pressure reduction.

A dual purpose pump for pressure vessels comprises a piston pump disposed within a pump cylinder. The piston pump is arranged in the interior of the pressure vessel and actuatable from the outside by piston strokes for building up an increased pressure in the interior of the vessel. The pump cylinder is mounted on the vessel and projects into the interior thereof. The present invention simplifies mixing, e.g. the preparation of an emulsion, by rotatably mounting the pump cylinder about its longitudinal axis. To accomplish this, a drive mechanism may be mounted on he outside of the vessel for rotating the pump cylinder and the pump cylinder takes mixing elements along with it which project into and thereby mix the liquid during rotation.

The invention relates to a hybrid engine comprising an internal combustion engine (E) and an electric engine (EM), which are connected to each other by means of a planetary gear. A clutch (5) is arranged in such a way that the internal combustion engine and the electric engine are connected to each other by means of a sun wheel and a planetary carrier (6). The invention also relates to a method for operating said hybrid engine.

In driver circuitry for driving an electro-optic display device having a row and column matrix array of pixels, including means for converting incoming digital display information signals into analog signals, sampling errors due to switch and column resistance and transmission delays are compensated by converting the digital samples for alternate columns (or rows) to analog signals having sampling errors of equal magnitude but opposite sign.

In a scrolling color projection system for displaying images represented by continuously updated frames of information, eg., video images, and employing a single, reflective electro-optic light modulator such as an AMLCD, flicker in the image caused by asymmetric electrical behavior of the light modulator is reduced without substantially reducing the brightness of the display, by addressing the modulator array at least twice during each frame period.

A splash guard device (1) having a framework (9) with a top edge (17), a bottom edge (18) and two side edges (19) that protects a portion of a screened-in area (2) from water, dirt and debris. The splash guard device (1) is preferably affixed along the top edge (17) to a screened-in area (2) such that the splash guard device (1) may be opened and closed in an upward and downward motion. The framework (9) preferably surrounds at least one see-through section (7) so as to give a more aesthetically-pleasing appearance.
