| 20080243441 | SIGNAL ANALYSIS METHOD FOR VIBRATORY INTERFEROMETRY - A signal analysis method for vibratory interferometry is disclosed in the present invention for measuring the vibratory characteristics of an object under test. The signal analysis method comprises steps of: obtaining a vibratory interferometric signal of an object under vibration; and analyzing the vibratory interferometric signal with a deconvolution operation to obtain a reformed vibratory interferometric signal. | 10-02-2008 |
| 20090010560 | METHOD FOR IMAGE CALIBRATION AND APPARATUS FOR IMAGE ACQUIRING - 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. | 01-08-2009 |
| 20090030631 | METHOD FOR ENHANCING THE MEASUREMENT CAPABILITY OF MULTI-PARAMETER INSPECTION SYSTEMS - A method for improving the measurement capability of multi-parameter inspection systems includes performing a measuring procedure to acquire a measured signature of a sample, calculating weighting factors representing a correlation between structural parameters of the sample by using a weighting algorithm, transforming the weighting factors into a sampling function by using a transforming rule, updating the measured signature to form an updated measured signature and generating a plurality of updated nominal signatures according to the sampling function, and comparing the updated measured signature and the updated nominal signatures to determine the structural parameters of the sample. | 01-29-2009 |
| 20100277744 | METHOD AND APPARATUS FOR RESONANT FREQUENCY IDENTIFICATION THROUGH OUT-OF-PLANE DISPLACEMENT DETECTION - A method for out-of-plane displacement detection is disclosed. The out-of-plane displacement is detected by analyzing all the fringe density indexes calculated using the frequency-domain information extracted from a series of interference images of the sample vibrating at different frequencies. The present invention further discloses a method and an apparatus for resonant frequency identification by detecting the peak value of all the fringe indexes calculated at different scanning frequencies. With the identified resonant frequency, the full-field vibratory surface profile of the sample in various resonance modes can be reconstructed. | 11-04-2010 |

| 20090148319 | Linear compressor with permanent magnets - This invention provides a compressor with brushless single-phase linear motor, which includes a movable cylinder associated with a permanent magnet array, at least a stationary electromagnetic winding set and a pair of stationary pistons. A partition plate is disposed in the movable cylinder to form a first sub-cylinder and a second sub-cylinder. The front ends of the pair of the stationary pistons are respectively placed in either of two openings of the movable cylinder at its two ends. An alternate current applied to the stationary electromagnetic winding set to generate alternately attracting/repelling forces to the permanent magnet array. The movable cylinder is hence alternately pushed forward and backward. The volumes of the first and second sub-cylinders are changed to compress air in the first sub-cylinder or the second sub-cylinder. | 06-11-2009 |
| 20110073119 | NEGATIVE PRESSURE ORAL APPARATUS - This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection between the interface and mouth or teeth and prevents the interface from falling off. The oral interface also provides fixation between upper and lower lips (or tooth) and prevents opening of patient's mouth during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft palate in a forward direction, the patentcy of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth ad prevent air from entering the oral cavity from atmosphere. The negative pressure will also pull the soft palate into contact with the rear surface of the tongue to create a seal that prevents the air from entering the oral cavity through the nasal airway. | 03-31-2011 |

| 20090065525 | NEGATIVE PRESSURE TYPE MEDICATION DELIVERING DEVICE AND MEDICATION DISPENSING DEVICE AND SYSTEM USING THE SAME - A medication delivering device includes a delivering unit and a negative pressure unit. The delivering unit includes a cylinder, a retractable part and a tip element. The cylinder has a first opening and a second opening. The retractable part connects the cylinder with the tip element. The tip element has a first end, a second end and a channel. The first end passes through the first opening and is received within the cylinder. The second end is located at an outlet of a pill container. The channel penetrates from the first end to the second end to link with the interior of the cylinder. The negative pressure unit connects to the second opening for providing negative pressure to the interior of the cylinder and the channel of the tip element, so that the tip element sucks up a pill on the outlet of the pill container. | 03-12-2009 |
