Patent number: 9638987Abstract: The camera side mount is brought, by relative rotation with the accessory side mount, from a first state where each accessory side bayonet claw is inserted between the camera side bayonet claws into a second state where the camera side and accessory side bayonet claws engage with each other. The leaf spring biasing the camera side contact pins in the protruding direction is disposed between the camera side mount and the camera body. When the camera being in the normal position is viewed from the direction facing the camera side mount, the leaf spring extends from both sides of the mount center line, which extends from the center of the camera side mount in the direction of gravity, toward the camera side contact pins. The camera side contact pins are arranged at positions other than a position on the mount center line.Type: GrantFiled: April 4, 2013Date of Patent: May 2, 2017Assignee: Canon Kabushiki KaishaInventors: Tetsuya Nishio, Yoshihiko Konno, Tatsuyuki Tokunaga, Takashi Hasegawa, Hiroshi Kikuchi, Azusa Sugawara

Patent number: 9638988Abstract: A light multiplexing system includes a color combining element and first, second, and third color channels. Each color channel includes a light source that directs light of a corresponding first, second, or third wavelength band, respectively, toward the color combining element. The color combining element includes first and second windows. The first and second windows are made of a solid transparent material and include, collectively, three coated surfaces. The surfaces may be non-contiguous. A first coated surface receives light of the first, second and third wavelength bands. The first coated surface reflects the light of the first wavelength band and transmits the light of the second and third wavelength bands. A second coated surface receives light of the second and third wavelength bands transmitted by the first coated surface. The second coated surface reflects the light of second wavelength band and transmits the light of the third wavelength band.Type: GrantFiled: December 9, 2014Date of Patent: May 2, 2017Assignee: Corning IncorporatedInventors: Joshua Monroe Cobb, John Weston Frankovich
