发明名称 MOVABLE BARRIER SAFETY CONTROL
摘要 Methods and apparatus for detecting obstructions in the path of a movable barrier are disclosed. Embodiments are included which advantageously combine edge sensing contact detectors and non-contact detectors such as photo eye detectors. Relay logic is also described for controlling the response of a movable barrier operator to input signals including input signals from contact type and non-contact obstruction detectors.
