Abstract: A laser detecting device able to detect and map all the contours a target object can configure and apply at least two scanning point groups on the target object. Each scanning point group includes at least two scanning points. The laser detecting device includes four light sources at different angles of incidence in relation to a diffracting element. A beam receiving element receives all the light reflected by the target object, and a central controller records emitting and receiving times of the light emitted and received. The detection beams sequentially scan the at least two scanning point groups as the central controller switches on in turn one of the four light sources as the others are powered off. Processing of data from the beam receiving element enables a three-dimensional image of the target object to be obtained.

Abstract: Provided is a heating device, which has an electric heating tube disposed in a sleeve-type carrier. The electric heating tube has two electrode portions and an opening end exposed from an opening of the carrier. When in use, a cigarette is placed in the carrier with tobacco of the cigarette filling the electric heating tube and encapsulating a periphery of the electric heating tube. As such, the tobacco of the cigarette can be directly and uniformly heated by the electric heating tube so as to achieve the purpose of heating the tobacco at low temperature.

Abstract: A method for fabricating a copper interconnect structure is disclosed. A substrate having a conductive region is provided. An insulating layer with a via opening is formed on the substrate. The via opening exposes the conductive region. A copper layer is formed on the first insulating layer and fills the via opening by sequentially performing deposition and reflowing processes. A masking layer is formed on the copper layer to cover the via opening. The copper layer uncovered by the masking layer is anisotropically oxidized. The masking layer and the oxidized copper layer are removed by a wet etching process, to form a copper plug in the via opening and a copper wire line on the copper plug. A copper interconnect structure is also disclosed.

Abstract: A method for progressive JPEG image decoding and a method for controlling a decoder are disclosed. In the image decoding method, an amount of macroblocks that can be stored during the process of decoding is determined according to the size of the memory, and then, according to the amount of macroblocks, a scan layer is divided into a plurality of decoding areas. In each turn of decoding, data of the same decoding area in all the scan layers are decoded. In the next turn, a decoding area next to the previous one is selected for decoding. Therefore, the present invention can decode the image correctly with a limited memory resource, without affecting the display quality of the image. The image decoding method also can be applied to the control of a decoder, so as to reduce the occupied memory capacity.

Abstract: A progressive JPEG image decoding method is provided. In the decoding method, a non-zero history table and a sign table of each variable length decoding (VLD) result are recorded and used as a reference for decoding the next scan layer. The decoded coefficients are no longer directly stored in a memory so as to save the memory space. Accordingly, an image can be decoded and displayed correctly even with limited memory space.

Abstract: A baseball bat structure includes a center portion in the form of a round bar, and at least one sheet-shaped wind wooden unit wound around the center portion. A direction of the grain of the grain portions of one layer of wind wood unit is different from that of the grain portions of a neighboring layer of wind wood unit, so that the grain portions of one layer of wind wood unit are arranged in a staggered manner with respect to the grain portions of the neighboring layer of wind wood unit, and therefore, the staggered grain portions can enhance the structure strength. Being laminated structures, the wind wood units can offer a better structure elasticity to the baseball bat structure, making the baseball bat structure less likely to crack while extending the service life.

Abstract: A collection process for precipitated powder substance is mainly for storing toxic or highly radioactive powder or dust in air and involves collection operation in water or other liquid to collect powder insoluble to the liquid and heavier than the liquid. To be suitable for underwater operation, a powder precipitation bag is provided with an innovative powder collection can at its bottom. New powder collection can has a mesh filter in its bottom and two-stage structure. After completion of powder collection, the collection can is pulled up from the water and dried to reduce powder volume and form powder lumps. Then, the top half is removed, so the collection can is fully filled with powder lumps. The newly designed powder can increases storage efficiency and reduces waste of space by accommodating more powder lumps than traditional powder can. With the same total amount of powder, the new powder can enables fewer number of storage cans.
