摘要:
The present invention relates to a method for image calibration and an apparatus for image acquiring. In the method for image calibration, the image formation position for an image acquiring unit of the apparatus is calibrated according to the relative location of the image acquiring unit to a objective lens of the apparatus, wherein the relative location is determined by calculating the focus index of the image acquired by the image acquiring unit so that a clear and sharp interferogram can be obtained for three dimensional surface profile measuring. In addition, it is possible to obtain a clear and sharp image without any interference fringe outside the coherent range by adjusting the image formation position, which is capable of being utilized for two dimensional defect detection and dimension measurement.

A flow unit for microfluidic particles separation and concentration is disclosed. The unit comprises a nozzle segment, a turn segment, and a diffuser segment. The nozzle segment is defined by a first member and a second member, and has an opening through which fluid and microfluidic particles enter. The nozzle segment has a narrowing portion at which the first and second members narrow from the opening to increase momentum of the fluid therethrough. The turn segment is defined by the first member flaring outwardly downstream from the narrowing portion to change flow direction of the fluid consistent with the first member. The diffuser segment is defined by the second member extending past the turn segment to facilitate separation of the microfluidic particles from the fluid due to the inability to follow the fluid flow.

The present invention discloses a negative-pressure oral apparatus capable of relieving discomfort of soft tissues in the oral cavity and improving fixation of the oral apparatus to prevent the oral apparatus from falling off due to mouth opening. The oral apparatus is compact and elastic so that it fits various shapes and sizes of the oral cavity and is easy to be put on and taken off to provide convenience and safety to the user. In another embodiment, a method for maintaining a negative oral pressure and collecting liquid by coupling the oral apparatus to a liquid collecting apparatus capable of effectively providing the oral cavity with a negative pressure to expel liquid in the oral apparatus and deliver the liquid to an absorbing element in the liquid collecting apparatus so as to prevent liquid leakage or contamination.

An electronic device with a covering lid for covering an insert hole includes a housing and the covering lid. The housing includes a first surface and a second surface which are connected to each other, and the first surface includes an insert hole. The covering lid includes a covering plate and a flexible handle, and the covering plate is disposed on the first surface and covers the insert hole. A first end of the flexible handle is connected to the second surface of the housing, and a second end of the flexible handle is connected to the covering plate. A bending portion is disposed between the first end and the second end to provide spring force to the covering plate to make the covering plate move along a direction away from the insert hole automatically when the covering plate is unfolded.

The present invention is a method and an apparatus for side-type heat dissipation. According to the present invention, a heat dissipation unit is deposed on a CPU to absorb the heat it generates; a cover is covered on the unit, where two openings are at two opposite ends and one of the openings has an inclined plane as well as a fan, and one of the openings is corresponding to a fan on the computer case; and an air flow is guided by a fan to the heat dissipation unit and is directed to a fan of a power supplier to be blown out of the computer case. By doing so, no thermal cycling will occur in the computer case and better heat-dissipation efficiency can be obtained.
