  • differential gear — differential (def 7).
  • differential line — (hardware)   A kind of electrical connection using two wires, one of which carries the normal signal (V) and the other carries an inverted version the signal (-V). A differential amplifier at the receiver subtracts the inverted signal from the normal signal to yield a signal proportional to V. This subtraction is intended to cancel out any noise induced in the wires, on the assmption that the same level of noise will have been induced in both wires. Twisted pair wiring is often used to try to ensure that this is the case. The two wires might be connected at the receiver to separate analogue to digital converters and the subtraction performed digitally. The RS-422 serial line standard specifies differential drivers and receivers, whereas the earlier RS-232 standard does not. Opposite: single ended.

  • douglas engelbart — (person)   Douglas C. Engelbart, the inventor of the mouse. On 1968-12-09, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, California, USA, presented a 90-minute live public demonstration of the on live system, NLS, they had been working on since 1962. The presentation was a session in the of the Fall Joint Computer Conference held at the Convention Center in San Francisco, and it was attended by about 1000 computer professionals. This was the public debut of the computer mouse, hypertext, object addressing, dynamic file linking and shared-screen collaboration involving two persons at different sites communicating over a network with audio and video interface. The original 90-minute video: Hyperlinks, Mouse, Web-board.
