Automatic door

An apparatus comprising:

• a command receiver that is operable to detect a command to open a door;
• a door opener that is operably coupled to the command receiver and that is operable to initiate opening of the door when the command receiver detects the command to open the door;
• an obstacle detector that is operably coupled to the command receiver and that is operable to be initiated when the command receiver detects the command to open the door, obstacle detector also operable to perform an obstacle detection process while the door is opening, the obstacle detector also operable to evaluate an obstacle warning parameter when an obstacle is being detected;
• and
• a device controller that is operably coupled to the door opener and the obstacle detector, the device controller being operable to halt the door opening when the obstacle warning parameter is set to NO, the device controller also operable to initialize a warning counter to a maximum number of iterations of a warning when the obstacle warning parameter is set to YES, the device controller also operable to perform a loop the maximum the number of iterations indicated by the warning counter when the warning counter is initialized, the loop providing an obstacle warning, and polling for a response, the device controller also operable to perform a predetermined default action when no response to the obstacle warning is received, the device controller also operable to perform a door command in accordance with the response when a response to the obstacle warning is received.
