Title: Electronic bubble-level indicator - light source beam is modulated by bubble interface and detected by photocell
Inventor: GOOLEY CORNELIUS LEONARD
IPC: G01C9/06
Filed: 1974-01-28
Abstract: The orientating device is applied to a test piece and indicates if it has the desired positioning. The device can be used in surveying, spirit levels, gun-sights, etc. It can be used in horizontal, vertical or other directions. A beam of light is radiated into a liquid cell in which a bubble floats. Movement of the bubble, as the long cylindrical cell is tilted, modulates the intensity of the light which is received in a photo-detector. A high gain amplifier raises the signal level and operates an indicator either locally or remotely. It can be arranged either that the output indicates a minimum or a maximum output when the desired orientation is achieved.
