  • Patent number: 9267682
    Abstract: An apparatus to change liquid light aromatic hydrocarbon into gaseity includes a gas storage barrel, two gas generation barrels and two gas connection pipes connected between the gas storage barrel and the respective gas generation barrels to form a “?” shape. Each gas generation barrel includes a light aromatic hydrocarbon filling pipe, an air supply pipe, an air intake pipe, an aeration pipe, and a heating member. A liquid communicating pipe is connected between the two gas generation barrels. The apparatus of the present invention is to mix and gasify liquid fuel, such as ether or alkanes, and air as combustion gas. During heating, the fuel can be resupplied to stable the quality of the output gas.
    Type: Grant

  • Patent number: 8184144
    Abstract: The present invention calibrates interior orientation parameters (IOP) and exterior orientation parameters (EOP). With the calibrated IOPs and EOPs, a remotely controlled camera can quickly obtains corresponding IOPs and EOPs no matter on panning, tilting or zooming. Thus, the remotely controlled camera obtains accuracies on imaging and measuring and obtains wide applications.

  • Patent number: 7701488
    Abstract: A system is used to remotely control camera positioning. A transformation model is used. By in putting image coordinates of the monitored position form camera, the object coordinates is obtained and displayed on a digital map. By inputting object coordinates on a digital map, image coordinates for the camera is obtained. After transferring parameters for camera positioning, the camera is moved to a desired position for monitoring an area and taking a photo.
