Abstract: A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

Abstract: A door frame system comprises a wall and a door frame. The door frame comprises a sub-buck portion and a shell portion, coupled to the sub-buck portion. The sub-buck portion comprises a sub-buck mounting arm including at least one mounting aperture, a sub-buck rabbet arm coupled to one end of the sub-buck mounting arm and a sub-buck support arm coupled to the sub-buck mounting arm opposite the sub-buck rabbet arm. The sub-buck portion is surface mounted to a single surface of the wall through the at least one mounting aperture.

Abstract: A system for monitoring an automated door assembly comprises a sensor, a local area network having a firewall, and a manager. The sensor is coupled to the automated door assembly and is in communication with the local area network. The local area network and the manager are connected to the internet. The manager and the sensor are capable of communicating by a handshake protocol.

Abstract: A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

Abstract: A door operator, for opening and closing a door with a motor, comprises a worm drive, a clutch coupled to the worm drive, and an output shaft coupled to the clutch. The worm drive comprises a worm and a worm gear. The door operator allows for the use of a low voltage motor to be used to open and close the door.

Abstract: A gear assembly comprises a housing, a first gear shaft in the housing, a first spiral gear coupled to the first gear shaft in the housing, a second gear shaft in the housing, a second spiral gear coupled to the second gear shaft in the housing, and a fluid connection between a first chamber and a second chamber. The first spiral gear and the second spiral gear couple to define the first chamber and the second chamber within the housing.
