    CAMAC and NIM systems in the space program (1975)
    In:  Other Sources
    Details
    Publication Date: 2011-08-16
    Description: The CAMAC and NIM instrumentation systems were developed originally to serve the needs of nuclear research institutions in Europe and North America. CAMAC and NIM are currently considered in several studies at the systems level conducted by NASA and ESRO groups. NIM and CAMAC studies for applications related to the space shuttle are discussed along with the advantages provided by aspects of modularization and standardization, a use of NIM and CAMAC equipment in connection with a group of astrophysics experiments, and questions of cost effectiveness.

    Automatic Exposure Iris Control (AEIC) for data acquisition camera (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A lens design capable of operating over a total range of f/1.4 to f/11.0 with through the lens light sensing is presented along with a system which compensates for ASA film speeds as well as shutter openings. The space shuttle camera system package is designed so that it can be assembled on the existing 16 mm DAC with a minimum of alteration to the camera.

    Automatic exposure control for space sequential camera (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: The final report for the automatic exposure control study for space sequential cameras, for the NASA Johnson Space Center is presented. The material is shown in the same sequence that the work was performed. The purpose of the automatic exposure control is to automatically control the lens iris as well as the camera shutter so that the subject is properly exposed on the film. A study of design approaches is presented. Analysis of the light range of the spectrum covered indicates that the practical range would be from approximately 20 to 6,000 foot-lamberts, or about nine f-stops. Observation of film available from space flights shows that optimum scene illumination is apparently not present in vehicle interior photography as well as in vehicle-to-vehicle situations. The evaluation test procedure for a breadboard, and the results, which provided information for the design of a brassboard are given.

    Leak detector (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A detector for sensing a leaking of fluid pressures is reported. The detector is characterized by an hermetically sealed housing confining therewithin a first normalized pressure, a connector for coupling the housing in direct communication with a suspected leak established within a substantially sealed body, an electrical circuit having a first or normalized configuration and including a pair of circuit completing electrical contacts and means mounting at least one contact of said pair of contacts on a flexible wall of the housing supporting the contact for movement from a first position along a linear path to a second position in response to an altering of the pressure confined within the housing for thereby altering the configuration of the circuit.

    The intensified charge coupled device as a photon counting imager (1975)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Actual and projected performance of an intensified charge coupled device (ICCD) to be used as a photon counting imager will be presented. Effects of tube processing on such important CCD parameters as charge transfer efficiency and dark current are discussed.
