Abstract: An image rendering method includes the following steps. Firstly, a source image is provided. Then, raster operations (ROPs) are performed on the source image by a first bit operating engine to obtain ROP values, and the source image are divided into at least one first region and at least one second region. Then, a first operation is performed on the first region by the first bit operating engine and a render process is executed, thereby generating first bit image data. Then, a second operation is performed on the second region by a second bit operating engine and a render process is executed, thereby generating second bit image data. Afterwards, the second bit image data of the second region are converted into first bit image data of the second region according to a screening table between the first bit operating engine and the second bit operating engine.

Abstract: An improved structure of power transmission apparatus, includes a power source supplier connected with a transmission shaft, a first driven element pivotally connected to the transmission shaft, a second driven element pivotally connected to a driven shaft and intermeshing with the first driven element, wherein both the first driven element and the second driven element are a gear being appropriately defined as a spur gear with a gear profile curve and having a pitch cone angle of a tooth, the pitch cone angle forming a first tooth curve and a second tooth curve, the pitch cone angle of the first driven element being in upside down relation to that of the second driven element to facilitate the first driven element and the second driven element being able to intermesh closely and smoothly with each other.

Abstract: A dynamic magnet apparatus for generating electrical power adapted to connect with a rectifier and accumulator, including a hollow elongated carrier having two opposite ends, a pair of fixed magnets positioned at outer surface of the opposite ends, a slidable magnet, and a supplemental weight, wherein the hallow elongated carrier is wrapped around by a number of coils, the fixed magnets disposed in polar opposition to the facing slidable magnet, the supplemental weight attached to the slidable magnet for increasing the weight of the slidable magnet. A feature of the present invention is that the supplemental weight can facilitate the slidable magnet traveling back and forth smoothly in the carrier due to a phenomenon of like pole repel of magnets. Another feature is that an inner surface of the carrier and an outer surface of the slidable magnet are of different profile in transverse for facilitating movement therebetween.
