Escalator and moving walkway system with safety sensor
First Claim
1. A system comprising:
- a conveyer,a sensor operationally directed to engage the conveyer,a controller for controlling the conveyer and the sensor,wherein the controller is configured to render a plurality of determinations including;
a first determination that the conveyer is in an operational state,a second determination that first sensed data dynamically obtained from the sensor is indicative of a first passenger on the conveyer,a third determination to model a shape of the first passenger, while the first passenger is on the conveyer, with a first nodal model,a fourth determination to track displacement differentials for the first nodal model,a fifth determination to identify from the differentials an occurrence of an alert condition with the first passenger,at an occurrence of an alert condition, a sixth determination to stop the conveyer, andthe controller is configured to transmit first instructions to the conveyer to effect the sixth determination.
