The invention relates generally to the field of motorized garage door openers. In particular, the invention relates to wireless safety sensors for garage door openers and garage door opener with a wireless safety sensor. The wireless safety sensor has a wireless communication link with a main control unit of the garage door opener. The wireless safety sensor also has an internal wireless link, i.e., a detection beam link, between a master unit and a slave unit. The wireless safety sensor periodically verifies that the wireless communication link has good signal quality and maintains the quality of the wireless communication link.

A system for determining a door condition includes a hinge including a first portion coupled with a door and a second portion coupled with a vehicle frame and rotatably coupled with the first portion. The system further includes a sensor outputting a signal related to a position of the first portion relative to the second portion and a controller receiving the signal and determining whether the signal corresponds to a door closed condition or a door open condition.

Example methods and systems to indicate the status of door operations are disclosed. An example door system includes a door panel having a leading edge to be moved in a travel direction between an open position and a closed position relative to the doorframe. The door panel to block the passageway when the leading edge is at the closed position. The door panel to unblock the passageway when the leading edge is at the open position. The example door system also includes a series of lights distributed along the travel direction proximate the doorframe. The example door system further includes a controller to switch the lights between a first state and a second state to provide a visual effect of movement corresponding to the operating status of the door system.
