| 20100275448 | Pneumatic saw power transmission structure - A pneumatic saw power transmission structure includes a main body, a first transmission module and a second transmission module installed adjacent with each other in a containing groove of the main body. The second transmission module includes a position limit device fixed at the main body for limiting the second transmission module in the containing groove of the main body to constitute the transmission structure of the present invention. | 11-04-2010 |
| 20100288522 | Pneumatic tool with an improved soundproof device - A pneumatic tool with an improved soundproof device includes a housing whose rear end has a screw hole for supplying a high-pressure gas. The input high-pressure gas drives a pneumatic motor before it leaves the rear end of the housing. A cover covers the rear end of the housing. The cover has a penetrating hole. A guiding element has a guiding section that gradually expands outwards. The guiding element goes through the penetrating hole. An annular ventilation space is formed between the guiding section of the guiding element and the penetrating hole. A gas inlet connector is disposed in the screw hole. The shoulder part of the gas inlet connector stops the guiding element, so that the gas in the ventilation space is guided by the guiding section of the guiding element to escape. | 11-18-2010 |

| 20120120024 | TOUCH SYSTEM AND OPTICAL TOUCH SYSTEM WITH POWER-SAVING MECHANISM - A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system. | 05-17-2012 |
