Abstract: A mobile printer having features particularly suited for use in a mobile conveyance such as an airplane. The printer stores a first data set in a memory that is accessed under control of a programmable controller. The printer then receives a second data set via a communications transceiver. Data from the first and second data sets are combined to form a composite bit mapped image which is printed by means of a thermal printhead controlled by the programmable controller.

Abstract: A control and take-up mechanism for controlling and protecting at least one elongated cable and the like which may be employed to supply operating power, fluids, controls and so on to an operating member mounted within an apparatus and wherein the operating member is selectively movable within the apparatus through an operating plane between a first position and a second position spaced therefrom. The take-up mechanism is comprised of an arcuate cable trough fixedly mounted to the apparatus in a plane parallel to the operating plane with a portion of the elongated cable leading to the operating member longitudinally disposed therein. A cable wheel assembly is received in the trough in rolling engagement therewith and includes a hub and opposed sides which define a cable channel therebetween.
