摘要： A method of constructing a low-tension wire array including the steps of arraying wires on an expandable frame expanding the wires past their elastic limit, and releasing the frame tension until each wire hangs in catenary. The wires are then placed onto an epoxied sheet and the ends cut.

摘要： This invention relates to a keyboard encoding device for converting the data represented by a key in a keyboard to a digital representation. The device employs a plurality of keys each individually operable to provide an acoustic shock wave in the form of a spark. Receptors arranged about the perimeter of the keyboard respond to the leading edge of the shock wave. The time period between generation of the spark and reception thereof by the shock wave receptor is digitized by means of a counting device responsive to the initiation of the spark and to the receipt of the shock wave by the receptor. Since each key is uniquely locatable with respect to the receptor, each key will produce a spark at a location which will take differing amounts of time to reach their receptor. The various digitization of these times are indicative or representative of the information attributed to each key respectively.

摘要： A coordinate digitizing device is provided with a localized source of magnetic energy positioned with respect to a wire array, each of said wires terminated in a common delay line. The magnetic energy is pulsed at a desired point, initiating a digitization time interval required for a pulse appearing along a wire of the array to traverse the delay line and reach a device for terminating digitization, and is an indication of the relative digital magnitude representative of the magnetic pulse device''s position above the array.
