Abstract: Terminals in a serial loop data transmission system automatically monitor input data to detect no data and mutilated data conditions. When either condition is detected, signals including the unique terminal address are automatically generated. The generated signals satisfy all down stream terminals and the central controller within a predetermined time is provided with the address of the terminal immediately following the fault and an indication of the type of fault.

Abstract: An optical encoding apparatus in which selected ones of a number of light conducting members are illuminated by a movable, independently selectable member, is disclosed. This movable member carries a coded array of illuminating areas. Photosensitive devices are associated with each of the light conductive members to indicate the illuminated condition of a given member, or array of members, in response to their being illuminated by the illuminating areas of the movable member. These photosensitive devices provide a coded output signal in the form of voltage or current information for use by other equipment which may utilize or be responsive to, or transmit the coded signals so produced.
