The invention is a seamless projection lithography system that eliminates the need for masks through the use of a programmable Spatial Light Modulator (SLM) with high parallel processing power. Illuminating the SLM with a radiation source (1), which while preferably a pulsed laser may be a shuttered lamp or multiple lasers with alternating synchronization, provides a patterning image of many pixels via a projection system (4) onto a substrate (5). The preferred SLM is a Deformable Micromirror Device (3) for reflective pixel selection using a synchronized pulse laser. An alternative SLM is a Liquid Crystal Light Valve (LCLV) (45) for pass-through pixel selection. Electronic programming enables pixel selection control for error correction of faulty pixel elements. Pixel selection control also provides for negative and positive imaging and for complementary overlapping polygon development for seamless uniform dosage. The invention provides seamless scanning by complementary overlapping scans to equalize radiation dosage, to expose a pattern on a large area substrate (5). The invention is suitable for rapid prototyping, flexible manufacturing, and even mask making.

A method for reducing random access memory (RAM) of an IC in display devices includes transforming a digital signal of a graphic data of three original colors (R, G, B) to digital signals of Y:Cb:Cr; taking one sample from two sample ratios of Y:Cb:Cr (4:2:0) or Y:Cb:Cr (4:2:2); storing in the RAM of a driving IC to reduce the RAM usage (with compressible data); then transforming the Y:Cb:Cr signals to three original colors (R, G, B) signal format to output image data, wherein Y represents brightness signal, and Cb and Cr represent color signals.

The invention discloses an edge information-based multi-scale blurred image blind restoration method, which comprises the following steps of: circularly and gradually restoring an image from a small scale layer to a large scale layer, setting self-adaptive parameters at different scales, and processing each scale layer, namely bilaterally filtering the restored image to obtain an image of which the noise and ripple are removed; performing shock wave filtering to obtain an image with high-strength contrast edges; solving the edges, and combining a fuzzy core initial value and a fuzzy graph to obtain an accurate fuzzy core; restoring a fuzzy image at the current scale to obtain a clear restored image by using the solved fuzzy core; sampling and amplifying in the current scale layer to obtain the restored image and a fuzzy core initial value of an adjacent large scale layer, and performing cycle operation on the adjacent large scale layer. The edge information-based multi-scale blurred image blind restoration method can effectively converge various images in different fuzzy degrees, and compared with a general blind restoration method which directly solves the energy minimization, the blurred image blind restoration method has the advantages of low computational complexity and high noise suppression capacity.

A video noise reduction system for a set of video frames that computes a first motion signal using a current frame and multiple consecutive previous frames, computes a second motion signal using the current frame and the processed preceding frame; computes the multi-frame temporal average of the current frame and multiple consecutive previous frames; computes the recursive average of the current frame and the processed preceding frame; generates a temporal filtered signal by soft switching between the multi-frame temporal average and the recursive average based on the first motion signal; applies a spatial filter to the current frame to generate a spatial filtered signal; and combines the temporal filtered signal and the spatial filtered signal based on the second motion signal to generate a final noise reduced video output signal.

In a sensor and a radar for measuring the distance and the moving speed of a target by radiating a radio frequency, particularly a millimeter wave, compatibility between cost reduction and high detection performance has been conventionally a significant problem. In the present invention, the frequency of a transmitted signal changes during a fixed time while performing digitally-frequency-modulation on frequency sweeping straight lines extending, with different slopes relative to the time axis, from plural slightly different initial values serving as starting points, the signal is transmitted after being modulated so as to periodically repeat the sweep time serving as a unit, signal components corresponding to the respective sweeping slopes are digitally sampled, in synchronization with the transmitted modulation signal, from a received signal which is reflected and returned from a target, and the received signal is analyzed.

An opportunity charging system for a battery-powered, mobile mining machine employs inductive power transfer for transferring battery charging current produced by a rapid charging station to the battery of the machine. An alignment module of the charging station automatically aligns primary coils of the charging station with pick-up coils carried by the machine in response to detection of the presence of the machine at the charging station. The charging station is located along roadways of the mine normally traveled by production equipment.

A sample of a body fluid such as blood or interstitial fluid is obtained from a body by lancing a portion of a user's skin, preferably in an area other than a finger tip, to form an incision. After the needle has been removed from the incision, a force is applied to depress the skin in a manner forming a ring of depressed body tissue in surrounding relationship to the incision, causing the incision to bulge and the sides of the incision to open, whereby body fluid is forced out through the opening of the incision. A stimulator member is mounted to an end of a lancet-carrying housing for applying the force. The stimulator member can be movable relative to the housing, and can be either heated or vibrated to promote movement of the body fluid.
