| 20110016935 | PUSHBUTTON LOCK - A pushbutton lock includes a lock core, a panel, and an interference unit. The lock core includes a case with a plurality of apertures, a plurality of button assemblies each movably disposed corresponding to a respective one of the apertures of the case, and a locking unit movably disposed on the case. The panel has a plurality of holes each for partially exposing one of the button assemblies. The interference unit is coupled with the locking bolt. The interference unit can move together with the locking unit to selectively interfere with the button assemblies and restrict the movement of the button assemblies. | 01-27-2011 |
| 20110041569 | LOCK - A lock includes a housing, a cable, a restrictor, and a lock unit. One end of the cable is fixed to the housing while the other end is detachably connected to the housing so as to selectively form an adjustable loop with the housing. The restrictor is rotatably disposed on the housing to selectively wedge together with the cable. The lock unit is disposed on the housing and can be selectively moved among a first position, a second position, and a third position. When the lock unit is moved toward the first position, the restrictor moves together with the lock unit to detach from the cable so as to allow the other end of the cable to disassemble from the housing. When the lock unit is moved to the second position, the restrictor restricts the cable to move toward a specific direction so as to shrink the adjustable loop. When the lock unit is moved to the third position, the restrictor wedges together with the cable, so that the length of the adjustable loop is fixed and not adjustable. | 02-24-2011 |

| 20110261348 | Optical Calibration and Testing Device for Machine Tools - An optical calibration and testing device for machine tools includes a light source unit, a beam splitter, and at least one photo detector. The light source emits a laser light hitting the beam splitter and is split into two beams. One is perpendicular to the foundation of the light source unit, and the other is parallel with the foundation so as to test straightness, inclination angle, verticalness, vertical column inclination, vertical column parallelism and guide bar inclination of a machine tool. If there is no tested error, the position of the testing light spot coincides with that of the initial light spot. If there is an error, the position of testing light spot varies according to the error. | 10-27-2011 |
| 20110292407 | OPTICAL PARALLELISM MEASUREMENT DEVICE - A high precision, rapidly operable optical parallelism measurement device includes a light source module, a light beam splitting module and at least two photoelectric detectors. The light source module has a light source and a light beam splitting element such that the light source module is able to produce two light beams perpendicular to each other. One of them is parallel to the moving direction, and is received by one of the detectors, while the other beam is split into two beams perpendicular to each other by the light beam splitting module. One beam is parallel to the former parallel by moving beam and is received by the other detector. With this scheme, the measurement can be performed by means of those perpendicular and parallel light beams without being affected by the structure of the machine platen to cause errors. The device can be manufactured with low cost and high precision. It is very compact in size and easy to carry and build up for rapid measurement. | 12-01-2011 |

| 20080292273 | Uniform Program Indexing Method with Simple and Robust Audio Feature and Related Enhancing Methods - Simple, computational efficient, and robust audio features are applied in a uniform program indexing method for picking up video segments relating to highlight plays in a recorded program worthy of being reviewed. By focusing on certain frequencies in an audio sequence of the program, a computational complexity of the uniform program indexing method is significantly decreased. With the aid of MFCC coefficients and a DFBE coefficient generated from the MFCC coefficients, audio patterns may be utilized for differentiating exciting events in the program from other unnecessary information. Scores corresponding to various audio segments are regarded as standards for picking up video segments in the program worthy of being chosen in a recorded highlight collection. Some low-level-feature parameters, some video segments having highlight-related visual characteristics, and a re-ranking procedure are utilized for enhancing precision of the scores for providing video segments worthy of being reviewed. | 11-27-2008 |
| 20090122189 | Method of Identifying Target Synchronization Point Pair through Scan-line Image Matching Scheme - A method of identifying a target synchronization point pair including a source synchronization point corresponding to a source end and a destination synchronization point corresponding to a destination end is provided. The method includes receiving a source scan-line image corresponding to a first video source from the source end; selecting at least a comparing frame out of the source scan-line image; providing a destination scan-line image corresponding to a second video source at the destination end; and determining the target synchronization point pair by comparing the comparing frame and the destination scan-line image. | 05-14-2009 |
