Abstract: A door assembly is provided. The door assembly includes: a guide frame unit including a first guide track and a second guide track spaced apart from and disposed in parallel with the first guide track; an inner door disposed to be upwardly and downwardly movable along the first guide track and provided with a first locking part protruding in a first direction at a lower end; an outer door disposed to be upwardly and downwardly movable along the second guide track and provided with a second locking part protruding in a second direction from above a point at which the first locking part is formed; and a drive unit configured to move the inner door upwardly and downwardly, wherein the second locking part is formed to contact the first locking part as the inner door moves upwardly.
Abstract: An agricultural vehicle including at least one threshing rotor and an auger bed located underneath the at least one threshing rotor. The auger bed has a working position and a cleaning position. The auger bed includes a frame, a plurality of augers rotatably coupled to and supported by the frame, and a trough portion moveably connected to the frame. In the working position the bottom surface of the trough portion is positioned underneath the plurality of augers and in the cleaning position the entire trough portion is moved relative to the frame so that the bottom surface of the trough portion is not positioned underneath at least a portion of the plurality of augers, creating an open space underneath the portion of the plurality of augers for allowing an unwanted material to pass therethrough.

Abstract: A method, system and computer program product for adaptively tracking the position of an entry portal, such as an automatic garage door. In accordance with the present invention a transmitter assembly senses and transmits the sensed position of the door position in a periodic manner at a predetermined transmit interval. A receiver assembly including a receiver module receives the transmitted door position signals and synchronizes the activation of the receiver module with the transmit interval such that the receiver receives the door position signals transmitted at the predetermined transmit interval. A receiver output indicator is then updated in accordance with the entry portal position determined by the received door position signal.
