Patent number: 8528218Abstract: Embodiments of a sundial. Various embodiments of the sundial disclosed herein may be used to determine the time of day based on the position of the sun. The sundial may comprise an at least substantially spherical curved reflector that may be at least partially transparent and at least partially reflective such that light from the sun can pass through a surface of the reflector and be reflected off of an internal surface of the reflector to reflect an image of the sun from the internal surface. The sundial may further comprise a dial face for viewing of a reflected image of the sun to provide at least an approximate indication of the time based on the position of the reflected image of the sun on the dial face.Type: GrantFiled: March 4, 2013Date of Patent: September 10, 2013Assignee: Heliosphere Designs, LLCInventor: Joyce Popendorf

Patent number: 8387265Abstract: Various embodiments of the sundials disclosed herein may be used to determine the time of day based on the position of the sun. The sundial may utilize a curved reflector to reflect the image of the sun onto a dial-face. The curved reflector may be disposed, at least in part, behind the dial-face. A portion of the curved reflector behind the dial-face may be used to reflect an image of the sun onto a back surface of the dial-face. The reflected image of the sun received on the back of the dial-face may, in some embodiments, be visible on the front surface of the dial-face. The dial-face may have a plurality of time markings positioned thereon. The position of the image of the sun on the dial-face may be compared to the plurality of time markings to determine at least an approximation of the time of day.Type: GrantFiled: January 10, 2012Date of Patent: March 5, 2013Assignee: Heliosphere Designs, LLCInventor: Joyce Popendorf
