Abstract
A control system includes a sensor system that may detect entry of a person into a detection curtain in front of a door, and a controller that may receive a first signal from the sensor system indicating the entry of the person into the detection curtain. The controller may determine a state of the door and generate a second signal responsive to receiving the first signal and while the state of the door indicates that the door can be opened. The control system also may include one or more actuators that may be coupled with the door and to open the door without the person touching the door responsive to receiving the second signal from the controller.
Claims20
A system comprising:
- a sensor system configured to detect entry of a person into a detection curtain in front of a door;
- a controller configured to receive a first signal from the sensor system indicating the entry of the person into the detection curtain, the controller also configured to determine a state of the door and to generate a second signal responsive to receiving the first signal and while the state of the door indicates that the door can be opened;
- and
- one or more actuators configured to be coupled with the door and to open the door without the person touching the door responsive to receiving the second signal from the controller.
A method comprising:
- generating a detection curtain in front of a door using a sensor system;
- detecting entry of a person into the detection curtain;
- determining whether a state of the door indicates that the door can be opened;
- and
- opening the door without the person touching the door using one or more actuators responsive to detecting entry of the person into the detection curtain and determining that the state of the door indicating that the door can be opened.
A system comprising:
- a sensor system configured to detect entry of a person into a detection curtain in front of a device;
- a controller configured to identify the entry of the person into the detection curtain based on output from the sensor system, the controller also configured to determine a state of the device and to output a signal responsive to identifying the entry of the person into the detection curtain and the state of the device indicating that the device can be actuated;
- and
- one or more actuators configured to be coupled with the device and to change the state of the device without the person touching the device responsive to receiving the signal from the controller.
