  • Patent number: 11965069
    Abstract: A heat-shrinkable polyester film made of a polyester-forming resin composition includes a recycled material, and has an exothermic crystallization peak and an endothermic melting peak which are determined via differential scanning calorimetry, and which satisfy relationships of T2?T1?68° C. and T3?T2?78° C., where T1 represents an onset point of the exothermic crystallization peak, T2 represents an end point of the exothermic crystallization peak and an onset point of the endothermic melting peak, and T3 represents an end point of the endothermic melting peak. A method for manufacturing the heat-shrinkable polyester film is also disclosed.

  • Patent number: 11956994
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

  • 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.

  • 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.
