Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: Provided is a method for diagnosing and monitoring progression of cancer or effectiveness of a therapeutic treatment. The method includes detecting a methylation level of at least one gene in a biological sample containing circulating free DNA. Also provided are primer pairs and probes for diagnosis or prognosis of cancer in a subject in need thereof.

Abstract: A method of accounting for manufacturing resource re-entry constraints in a manufacturing planning system includes: building a relationship from a manufacturing operation to be rendered on lots of material, to a plurality of manufacturing resources capable of performing the operation, wherein at least one of the manufacturing resources is also capable of performing the operation on ones of the lots having manufacturing resource re-entry constraints; selecting one of the lots of material; selecting from any of the plurality of manufacturing resources in the relationship a manufacturing resource for performing the operation if the selected lot of material has no manufacturing resource re-entry constraints; and selecting from any of the at least one manufacturing resources in the relationship a manufacturing resource for performing the operation if the selected lot of material has manufacturing resource re-entry constraints.

Abstract: A musical picture frame for generating music for a picture frame and creates an elegant and romantic atmosphere for the memory. The picture frame can be inserted into a musical structure which is composed of a pressure seat, a rubber conductor, a PC board and a base seat. With fingers pressing on the pressure seat, the rubber conductor will be forced to contact with the PC board circuit and proper music will then generated.

Abstract: Oversprayed paint in a paint spray operation is detackified by dosing the water of the waste water system of such operation with a composition comprising a polymer and aluminum sulfate. The polymer contains at least about 10 mole percent of cationic mer units of monoethylenically unsaturated monomer.

Abstract: A method of paint sludge conversion and sludge removal from a sump pit for disposal is provided which is particularly adapted for use with paint waste sludge derived from wet spray booth operations. The method involves blending with the starting sludge caustic, oil and emulsifiers. Water may be added to achieve a desired water to total solids weight ratio. The product is a pumpable liquid disperse system which is easily charged to tankers or the like for pump out from the sludge pit.

Abstract: Both waterborne and solvent enamels can be sprayed in a common paint spray booth and be detackified by a composition comprising a blend of a melamine-formaldehyde polymer, polyvinyl alcohol and a styrene acrylate copolymer. The invention also contemplates the use of these compositions in detackifying paint in paint spray booths.

Abstract: A method of conditioning sludge formed in paint spray booths, where the detackifier is a melamine-formaldehyde, polyvinyl alcohol and styrene-acrylate paint detackier by adding a water conditioner that includes acrylamide/dimethylaminoethylmethacrylate methylsulfate quat.
