Abstract: An optical scanning unit particularly adapted for use in remote optical character recognition systems or the like and including a document feed drum together with a rotating mirror arranged to sweep a narrow beam of light on a scan path across the drum while the latter is stationary between indexing steps, there being provided adjacent the scan path an elongate strip of semiconducting material of the PIN type arranged to produce electrical output signals in response to incident light reflected from the scanning sweep across the document, thereby to develop scan signals indicating the presence or absence of character elements along the scan path.

Abstract: A central time-shared data processing system organized for character analysis and coupled to a number of remote document scanning stations each including a drum document feed, the drum being rotatable in small incremental steps, and means operable between steps for scanning the document along a path parallel to a line of characters on the document to produce data identifying graphic figures for analysis by the central processing system.

Abstract: Test equipment for verifying trunk routing in a telephone system by developing, in response to a verification request, a series of spoken words identifying the area code and the telephone exchange to which the trunk under test is connected. The equipment includes a plurality of input channels each coupled to the verification line for a corresponding telephone exchange. A ringing signal on any channel is detected and a binary flag is set in an associated latch. All of the latches are scanned in rotational sequence by a multiplexer which, when a flag is detected, stops scanning and initiates a read-out operation from a speech-generating unit having a number of selectable speech signals stored in digital format in a read-only memory. Special logic circuitry is provided to identify the required telephone exchange digits, and to produce a read-out of the area code and exchange digits in sequence. The digits which are developed in response to a verification request are controlled by manuallyinsertable encoding keys, permitting customer modification of the predetermined voice response.
