Abstract: A data acquisition and transmission system for surveying a plurality of remotely location jukeboxes via telephone lines. A data collector, operatively associated with each jukebox, includes a song identification arrangement and storage memory for determining the number of times a particular song is played over a given period of time. At regular intervals, a central station contacts each data collector via telephone and requests the stored information which is subsequently transmitted via telephone lines to a central computer which tabulates and stores the information. The collected data is then processed to provide a distribution scale useful in determining the proper allocation of royalty fees received from jukebox licensing fees.

Abstract: A combined scanning spectrophotometer-digital data processing system including a microcomputer is described for making appearance measurements. The instrument is comprised by an optical sensing unit and a signal processing unit. The optical sensing unit utilizes a simulated D65 light source lamp together with an 8 inch diameter integrating light sphere for use primarily in the diffuse polychromatic illumination of reflectance test specimens but which also is used with transmittance test specimens. Light leaves the sphere through a transmittance port in which a transmittance test specimen may be disposed in the case of transmittance measurements. The light sphere further includes a reflectance port for making reflectance measurement of a test specimen placed at the reflectance port.
