Abstract: A motor driven door assembly is provided, the motor driven door assembly includes a door frame, a motor assembly connected to the door frame and having a motor directly connected to a first portion of a door hinge, and a door connected to the door hinge. The door hinge includes a second portion supported by a bearing assembly that carries substantially all of the door's weight, and the motor directly drives the door hinge to open or close the door.

Abstract: A local area network (LAN) system is provided that is capable of accommodating a variety of computer subsystem types, and having a LAN controller which can control at substantially the same time a plurality of LANs of the same type or a plurality of different types of LANs.

Abstract: A programmable communications processor is coupled to execute instructions of programs designed to process the transfer of information between a plurality of communication channels and a main memory included in the system. A software implemented and controlled pause counter enables the execution of a given maximum number of instructions for servicing, for example, a communication channel following which it suspends or pauses such servicing, in order to service another higher priority request which may be pending. Processing of lower priority service requests thus cannot delay the recognition and handling of higher priority requests for more than a minimum period of time and the effective throughput rate is increased.

Abstract: An apparatus for detecting a locator, e.g. a notch, perforation or mark, associated with each frame of an elongated film strip that is advanced through the apparatus. The apparatus includes guide members that are supported adjacent opposite longitudinal edges of the strip and a detector, such as a photoelectric cell and a light source, for sensing the locators. The guide members and the detector are coupled for movement in a direction transverse to the general direction of advancement of the strip and move in response to transverse wavering movement of the strip to ensure proper positioning of the detector relative to the locators as the locators approach the detector.
