    • The connector and mounting device of this invention is used to mechanically and electrically interconnect a printed wiring board and a backpanel without the use of mounting devices (such as screws) in the contact area of the connector. The elimination of mounting devices permits greater packaging densities (closer spacing) of components on the printed wiring board. The connector comprises an elongated block of insulative material having plural transverse channels, a spring contact in each channel is affixed on one end thereof to the printed wiring board and the other end of the spring contact is yieldingly retained within the channel. Each contact is formed to provide an intermediate contact portion protruding exteriorly of the connector block. The printed wiring board with the connector attached as hereinbefore described is inserted into a U-shaped mounting device which holds and guides the assembly on the backpanel. A biasing retainer cap containing a waveform spring is attached to the mounting device so as to spring-load the printed wiring board connector assembly into conductive contact with the backpanel.

    • A high-density storage and retrieval system is disclosed in which information is divided into a succession of groups of binary digits and stored as patterns of representations in an associated plurality of storage cells in a record medium. Upon scanning each recorded pattern of representations, a transducer generates an electrical signal having one discrete analog waveform uniquely corresponding to each of the recorded patterns of representations. A set of sample signals is then generated by sampling each discrete analog waveform at critical points. Each such set of sample signals is summed by correlation techniques requiring the adding and subtracting of the various individual sample signals to generate a sum signal. The magnitude of the sum signal is correlated to, or related with, a reference magnitude which is representative of a sum signal corresponding to a known analog waveform. As a result of this correlation, the magnitude of each sum signal is recognized as being indicative of a particular group of binary digits. The use of correlation techniques allows for the cancellation and averaging of analog waveform imperfections, and results in a sum signal which more accurately corresponds to the analog waveform detected.
