发明名称 Sundial
摘要 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.
