    Abstract: An engine valve timing control system using electrohydraulic valve lifters or adjusters (51, 52, 53, 54, 55, 56, 57, 58) operatively connected to a microprocessor based electronic control unit (32) will provide real time charges in engine valve timing. As a result, engine performance will be improved over the mechanically controlled engine valves which at best are compromises between engine operating extremes. Each lifter is "homed" to the base circle of the cam through the use of check valves (67, 69, 69a) and high pressure pulses generated in the oil lines (60) supplying the lifters.

    Abstract: An electronic display for presenting to an aircraft flight crew the combined information outputs of a vertical speed sensor and a TCAS computer aboard an aircraft. TCAS traffic advisories, i.e. the locations of other aircraft in the vicinity of the protected aircraft, are presented in a first display area of an electric display panel, preferrably in PPI format, showing range, relative bearing and relative altitude, if known. Vertical speed of the protected aircraft is indicated in a second display area adjacent the first display area on the same display panel. Whenever the TCAS computer determines that a particular aircraft constitutes a collison threat and that the establishment or maintainence of a specific flight path is necessary to minimize the probability of collision, the TCAS computer issues a resolution advisory which is displayed by identifying the threatening aircraft with a characterizing symbol in the first display area and by indicating symbolically and by other distinctive visual means, such as contrasting colors, in the first and second display areas the specific flight path to be established or maintained.
