  • Patent number: 9672426
    Abstract: An intelligent monitoring system for care place is illustrated. The system includes a thermal camera capturing a thermal image of the care place; an image processing unit obtaining user's position and number of user according to region in which temperature is higher than a preset temperature in the thermal image; a temperature recording unit extracting and records user's temperature from the thermal image. When there is only one user, a abnormal event determining unit of the system determines whether an abnormal event occurs according to user's temperature changing rate. When there are several users, the abnormal event determining unit determines whether the abnormal event occurs according to both of the temperature changing rates of the users and an average temperature of the users. If the abnormal event occurs, the warning unit generates a warning signal.

  • Publication number: 20140063836
    Abstract: A laser lighting device, including a laser light source and a light pipe, is disclosed. The laser light source can produce a laser beam with a diffusion angle not larger than 30 degrees. The light pipe is disposed in a light path of the laser beam, and has a light incident surface, a light exiting surface and several cut planes. The light incident surface is opposite to the laser light source, and the cut planes are located between the light incident and light exiting surfaces. Each of the cut planes is normal to the longitudinal direction of the light pipe, and has an area smaller than that of the light exiting surface but larger than that of the light incident surface. The areas of the cut planes increase sequentially along the longitudinal direction. The laser beam will be effectively collimated by the light pipe after passing through the light pipe.

  • Patent number: 8632237
    Abstract: A light guide plate with an adjustable illumination angle and an illumination device using the same are provided. The light guide plate has a first surface and a second surface opposite to the first surface. The second surface further has a plurality of deformable microstructures thereon. The deformable microstructures will be deformed when an external force is applied to the deformable microstructures. The illumination device has a light source and a light guide plate that is disposed next to the light source. A light beam emitted from the light source enters into the light guide plate and leaves the light guide plate via reflecting or refracting by the deformable microstructures. By applying a different external force to the light guide plate, the deformation of the deformable microstructures will be varied. Therefore, the illumination angle of the light beam could be changed according to the deformation of the deformable microstructures.
