20140021237 | SPRING BIASED LOCK FOR MAGAZINE OF NAIL GUN - A magazine of nail gun is provided with a nail receptacle; a cover slidably mounted on the receptacle; a cavity on an uneven bottom of the cover; a first hole from the cover to the cavity; a spring biased button in the first hole; a first retaining member secured to the button and urging against a bottom of the cavity so as to retain the button; a second hole through the receptacle and aligned with the first hole; a spring biased detent in the second hole and projecting out of the second hole to urge against a bottom of the button; and a second retaining member secured to the detent and urging against the bottom of the receptacle so as to retain the detent. The cover is locked by the receptacle in a storage position of the magazine. | 01-23-2014 |
20140034700 | NAIL GUN CAPABLE OF PREVENTING ITS TRIGGER FROM BEING PULLED IN NAIL-EMPTY CONDITION - A nail gun capable of preventing a trigger from being pulled in a nail-empty condition is provided. The nail gun includes a housing connected with a trigger, a muzzle, a nail driving member moveably mounted in the muzzle and a nail magazine communicated with the muzzle for accommodating nails and a nail pushing member for pushing the nails toward the muzzle, and a side of the nail pushing member has a locking portion; and a safety member moveably mounted to the muzzle for upward or downward movement. An end of the safety member has a stop portion. A position of the locking portion is corresponding to that of the stop portion for selectively stopping the upward or downward movement of the safety member. | 02-06-2014 |
20150059546 | RIP FENSE WITH LOCKNG MECHANISMS - A table saw includes a movable rip fence and a base including an upper cutting surface through which a blade extends. The rip fence includes front and rear clamping mechanisms connected to front and rear ends of a casing respectively. The front clamping mechanism includes a frame, a lever pivotably secured to the frame to be pivotal between a locked position and a released position, the lever having an internal cam member, a clamping member pivotably secured to the lever, the clamping member having a hook at an open end, a spring biased shaft, and a C-clip for retaining an inner end of the shaft in the frame. A pivotal movement of both the lever and the clamping member causes the cam member to push the shaft inward until the shaft is pushed outward to urge against the cam member in the locked position. | 03-05-2015 |
20150059547 | SUPPORTS FOR A TABLE SAW BLADE ASSEMBLY - Supports for a table saw blade assembly are provided and each support includes an elongated L-shaped bracket releasably secured to the upper cutting surface and including a curved slot; a pivotal plate including a projection slidable in the curved slot, and two holes through the projection and the pivotal plate; a first clamping plate; and a second clamping plate. The first clamping plate, the bracket, the pivotal plate, and the second clamping plate are fastened together with the pivotal plate being capable of sliding along the curved slot. | 03-05-2015 |

20100321340 | System and Method of Distinguishing Multiple Touch Points - The invention discloses a method of distinguishing multiple touch points applied to an optical touch system which includes a panel for indicating a first touch point and a second touch point thereon and a camera unit for capturing an image relative to the first touch point and the second touch point. The image has a first dark area and a second dark area corresponding to the first touch point and the second touch point respectively. In the method, if it is observed that the first dark area and the second dark area merge into a first single dark area and a second single dark area at current time and previous time respectively, the respective positions of the first dark area and the second dark area are determined based on the respective union dark area widths of the first single dark area and the second single dark area, and the respective coordinates of the first touch point and the second touch point are determined according to the respective positions of the first dark area and the second dark area. | 12-23-2010 |
20110102376 | Image-Based Coordinate Input Apparatus and Method Utilizing Buffered Imates - The invention provides an image-based coordinate input apparatus and method for detecting positions of N objects on a coordinate input region at a detecting interval where N equals to 1 or 2. According to the invention, starting at the start of the detecting interval, successive first images at a first view and successive second images at a second view relative to the N objects and a background of the perimeter of the coordinate input region are captured and buffered. The apparatus and method according to the invention judges the number of the N objects and calculates the positions of the N objects on the coordinate input region at the detecting interval in accordance with the buffered successive first images and the buffered successive second images. | 05-05-2011 |
20110119579 | METHOD OF TURNING OVER THREE-DIMENSIONAL GRAPHIC OBJECT BY USE OF TOUCH SENSITIVE INPUT DEVICE - The invention provides a method of turning over a three-dimensional graphic object by use of a touch sensitive input device. In particular, the method according to the invention provides a user with intuitive operation on a touch sensitive surface of the touch sensitive input device to turn over whole or a portion (e.g., a page sub-object) of the three-dimensional graphic object. | 05-19-2011 |
