ABSTRACT:
A digital sensor network scanner for use in monitoring resin flow and its re progress during a resin fabrication process in which a plurality of non-intersecting electrically conductive threads are arranged in a grid-like configuration with each sensor thread having a sensor input for a sensor data path so as to create a plurality of sensors is disclosed in which a first section of the scanner supplies time encoded pulses to the sensor input path. A second section of the sensor network scanner includes a plurality of detectors which are connected to the sensor data path as well as to a plurality of LEDs and which are also triggered by the same time encoded pulses applied to the sensor input path. When a sensor data path is in a conducting state, the applied time encoded pulses propagate down the sensor data path to the detector which, having simultaneously received a signal from both the network scanner and the sensor, illuminates the LED.
