  "Signal distribution in automatic checkout systems."

  This paper deals with several selected aspects of the signal distribution in automatic checkout systems. These are: 1) The use of relay matrices as control elements; 2) The inclusion of self-checking capabilities; 3) Problems of systems integration. These aspects are not unique to automatic checkout systems. However, due to the nature of automatic checkout systems as presently being designed around digital circuitry, they find either fuller or different applications than in other types of systems. Also, while they are on the surface somewhat disconnected in nature, they tend to interrelate during the implementation of an automatic checkout system.

  "Meteoroid measurements with Project Pegasus."

  Presentation at the Northeast Electronics Research and Engineering Meeting, Boston, Massachusetts, November 4, 1965. Ernest Stuhlinger, Director, Research Projects Laboratory, George C. Marshall Space Flight Center (NASA), Huntsville, Alabama.; INTRODUCTION: The prime objective of Project Pegasus is to measure, in the vicinity of the earth, the meteoroid penetration frequency in aluminum sheets of thicknesses which approach those of space capsule walls. Plans for the project were initiated at NASA in 1962 by the Office of Advanced Research and Technology and the George C. Marshall Space Flight Center. Throughout the project, members of the Langley Research Centers supported the project with experiments and advice.
