Patent number: 9377676Abstract: An autostereoscopic display device includes a projector, an angle-enlarging module, a screen, and a polarization selector. The projector provides a lamp image unit with a first polarization state. The angle-enlarging module includes a deflecting plate, a wavelength retarder, and a polarizer. The deflecting plate has a first deflecting segment and a second deflecting segment alternately with each other. The first and the second deflecting segments respectively deflect the lamp image unit to a first direction and a second direction different from each other. The wavelength retarder has a transmitting segment aligned to the first deflecting segment and a wavelength retarding segment aligned to the second deflecting segment. The transmitting segment maintains the first polarization state when the lamp image unit passes therethrough. The wavelength retarding segment converts the first polarization state into a second polarization state.Type: GrantFiled: June 5, 2014Date of Patent: June 28, 2016Assignee: DELTA ELECTRONICS, INC.Inventor: June-Jei Huang

Patent number: 9349044Abstract: A gesture recognition apparatus and method are provided. The gesture recognition apparatus includes an imaging device that is configured to photograph a gesture recognition region and generate image information and a distance sensor that is configured to sense a particular object that approaches a gesture start position. A controller is configured to enter a gesture input mode when the particular object is located at the gesture start position for a predetermined time and recognize a gesture by detecting the particular object based on the image information. Further, the controller is configured to provide feedback that indicates whether the particular object is located at the gesture start position and feedback that indicates whether the particular object is located in the gesture recognition region in the input mode.Type: GrantFiled: August 27, 2014Date of Patent: May 24, 2016Assignee: Hyundai Motor CompanyInventors: Sihyun Joo, Jongmin Oh, Jungsang Min

Patent number: 9151959Abstract: An optical system that projects a real image to a location in free space and includes one or more features located along the optical path that enhance the viewability of the real image. The optical system includes a converging element for converging a portion of source light so as to form the real image. One viewability-enhancing features is the use of a broadband reflector-polarizer having high transmitting and reflecting efficiencies. Another viewability-enhancing features is the use of polarizing elements having substantially matched bandwidth responses and/or comprising an achromatic design. An additional viewability-enhancing feature is the use of a wide-view film to increase the viewing angle of the image.Type: GrantFiled: November 21, 2011Date of Patent: October 6, 2015Assignee: PC Mirage, LLCInventor: Bruce D.
