Patent ID: 7106660

Claim:
A sun dial comprising a cylindrical housing having a central upstanding post, a light detector mounted on the top of the upstanding post exposed to detect ambient light, a logic circuit mounted in the housing for processing detected light including a timing circuit for resetting the logic circuit at 24 hour periods, a plurality of tactile switches for controlling the logic circuit mounted in the housing adjacent its top surface arrayed arcuately adjacent the peripheral edge of the top surface of the housing over an arc of about 60 degrees, at least three LEDs controlled by the logic circuit arrayed in an about 60 degree arc on the top surface of the housing adjacent it periphery diametrically opposed to the tactile switches, indicia marked on the top surface of the housing associated with the LEDs to indicate at least three conditions of sunlight, whereby the logic circuit processes the detected light to determine the condition of sunlight and when controlled by a selected tactile switch an associated LED will light to show the current condition of sunlight, and when controlled by another selected tactile switch an associated LED will light to show the average sunlight.
