Disclosed is an optical switch using V-beam electrothermal actuators, buckle beam springs, and movement translation mechanism with its bi-directional movable latched function for optical communication applications. In the preferred embodiments, various layout combinations of the V-beam electrothermal actuators, the buckle beam springs, a reflective mirror shutter connected to a shutter beam, and spatial joint to enable various operation approaches to realize the bi-stable switching function without external electrical load and electrical power consumption of said optical switch regarding the input optical signals transmitting toward the output channels, or the input optical signals transmitting forward to the reflective mirror shutter and then being reflected toward the output channel. The forward moving displacement generated by electrothermal V-beam actuators will move the shutter beam and reflective mirror shutter from one stable position to another stable position of the bi-stable positions of latched optical switch. The buckle beam springs exert spring force due to its natural deflection onto the shutter beam against the force from actuators, environment vibrations, and shocks, etc.; thus the optical switch performs the latch function with any external electrical load and electrical power consumption.

An apparatus for providing a file to a target device comprises a communication controller and a processor. The processor acquires download status indicating that a portion of the file has been successfully programmed in nonvolatile memory of the target device, determines a resuming point of the file according to the acquired download status, and transmits a portion of the file from the determined resuming point to the target device via the communication controller. The portion of file is programmed in the nonvolatile memory of the target device.

A system for document classification with multiple dimensions and multiple algorithms. The system includes a preference database, a generator, and a classification unit. The preference database stores at least one classification preference. The classification preference includes a plurality of categories, each of which has a corresponding algorithm. The generator transforms the classification preference into a classification code. The classification unit executes the classification code to classify the document, thus one or several detailed catalogues corresponding to each of the categories are acquired.

A cutter for trimming tiles comprises generally a flat rectangular base, a first trapezoidal seat pivoted to one end of the base, a second trapezoidal seat sliding about an arcuate rail perpendicular to the other end of the base, a pair rail rods extended parallel to the axis of the base and secured at their two ends into the first and second trapezoidal seats respectively so that the rail rods can laterally swing about the arcuate therewithin. A cutting tool slides about the rail rod thereon having a cylinder shaft attached with a handle and a blade rotatably secured to the center of the cutting tool. So that cutter of the present invention can trim a straight line, a beveled straight line, a curve or a circle in a tile.

A stacked-type piezoelectric device includes a stack of piezoelectric layers, plural conductive layers, a first contact hole, a second contact hole, and plural insulating portions. The piezoelectric layers are disposed between the conductive layers. The first and second contact holes penetrate the piezoelectric layers and the conductive layers, and each of first and second contact holes is filled with a conductive material. Every insulating portion is formed at one conductive layer. Two adjacent insulating portions are respectively formed at the outer rims of the first and second contact holes, to electrically isolate the conductive layer (in which the insulating portion is formed) from the conductive material in the contact hole.

A flip chip device made using LCD-COG (liquid crystal display-chip on glass) technique. The flip chip device comprises a substrate, at least one chip having active area with a plurality of compliant bumps thereon. The compliant bumps are centrally disposed in the center of the chip for electrically connecting the chip and the substrate. An adhesive is daubed on a joint area of the substrate and the chips for jointing the substrate and the chips. By limiting the position of the compliant bumps so that they are centrally disposed on the chips, the thermal warpage of the substrate is reduced.
