Abstract: Systems and methods that display information to enable a flight crew on a trailing aircraft to maintain separation behind a leading aircraft during an approach. Graphical designs are displayed on a navigation display or other display in the flight deck of the trailing aircraft to help the flight crew visually acquire the leading aircraft out the window and maintain at least a specified separation distance or spacing between the two aircraft even if visual contact is lost after the initial visual contact. A visual indication is provided on the display if that separation distance/spacing is attained. If for some reason the flight crew misses that visual indication and the trailing aircraft continues to get closer to the leading aircraft, another visual indication is provided, followed by an aural alert when a minimum safe spacing is reached.

Abstract: A method and apparatus of turning an aircraft for interval management. Interval management information identifying a desired spacing between the aircraft and a target aircraft is received. Turn information is determined using a performance gain factor. The turn information identifies a turn point for the aircraft. The performance gain factor identifies a desired portion of achieving the desired spacing due to turning the aircraft at the turn point and a desired portion of achieving the desired spacing due to changing speed of the aircraft. The turn information is used to turn the aircraft at the turn point.

Abstract: A system is disclosed which may be used for collecting television channel tuning data, household purchase data, VCR channel usage data and the like; on site at a plurality of preselected households, wherein the system concentrates and transmits the collected data to a central site in a fault tolerant manner, transparent to the occupants of the household. The novel system features a hub and spoke architecture for effecting communications between the central site and each household (remote site). The hub and spoke architecture at each remote site comprises a hub unit, and a set of spoke meters. The hub unit is adapted to be coupled, in a variety of ways, to a set of metering devices, one or more of which is coupled to one or more television receivers and/or cable television converters. Not all of the metering devices need be coupled to the television receiver or cable converter, e.g., stand alone purchase meters and wands may be coupled to the hub. The meters may be polled systematically, e.g.

Abstract: A rotary combustion engine having two fuel injection nozzles, both mounted in the rotor housing on the downstream side of a trochoid lobe junction in the region in which combustion takes place, with both nozzles discharging in a generally upstream direction and with a spark plug disposed adjacent to the upstream one of said nozzles.

Abstract: A rotary engine having a pair of fuel injection nozzles disposed adjacent to and on opposite sides of a lobe junction of the rotor housing in the combustion region and a spark plug is disposed adjacent to the fuel nozzle which is disposed on the downstream side of said junction.

Abstract: A rotary combustion engine having grooves in the engine side walls for bleeding off unburnt hydrocarbon gases from the trailing end of each working chamber during the late portion of its expansion stroke, these gases being bled through side housing grooves into the space between oil and gas seals on the sides of the rotor from which space the unburnt gases are returned to a working chamber during the intake stroke of said chamber.

Abstract: The improved fuel injection system is for a rotary internal combustion engine having a housing within which a rotor is disposed for planetary rotary motion and which defines with the housing a plurality of combustion chambers. The improved fuel injection systems has a positive displacement fuel pump, such as of the plunger and barrel type, which is connected to deliver fuel to a fuel nozzle located to emit fuel into the combustion chambers upon actuation of the plunger. An actuating means, such as multi-profile cam is supported for rotation at a speed proportionate to rotor speed and disposed to effect reciprocative movement of the plunger.

Abstract: A rotary combustion engine having a fuel nozzle for discharging fuel into each working chamber just prior to combustion and in which means are provided for increasing the width of the spray angle of the fuel discharged by said nozzle as the quantity of fuel discharged by the nozzle into each working chamber is increased.

Abstract: A rotary combustion engine having two fuel nozzles for discharging fuel into each engine working chamber with fuel being discharged from only one of the nozzles during low power operation of the engine and being discharged from both nozzles during high power operation of the engine.
