Abstract: An unlocked, digital sequencer circuit having flexibly ordered leading and trailing edges on the output signals. The sequencer circuit of the invention includes a dual-input latch that detects only leading edges on a first input termfinal and only trailing edges on a second input terminal. A delay line provides successively delayed input signals. Two delayed input signals are coupled to the first and second input terminals of each of two or more dual-input latches that provide a set of sequencer output signals. The sequence of the output signal edges depends on which delayed input signals are selected to drive each dual-input latch. In one embodiment, the selection of delayed input signals to drive the first and second input terminals of the dual-input latches is programmable. Thus, the sequence of the leading edges on the output signal is programmable, and the sequence of the trailing edges is independently programmable.

IPC: H02K11/00
Filed: 2002-10-30
Abstract: A non-conductive insulating ring (210) is inserted between a motor bell (130) and a motor bearing (135) that supports a motor shaft (110). Stray currents that normally discharge through the moto r shaft and the motor bearing to the motor bell are prevented due to the non-conductive nature of the insulating ring. Additionally, the motor shaft may be grounded to provide a low-impedance alternative path to stray shaft currents. When a fast-switching frequency converter is used to drive the motor shaft, additional arrangements such as a common mode choke, reduction of the switching frequency of the converter, and reduction of the turn-of/off rate of a semiconductor device used in the converter, may be provided to further reduce the stray currents flowing through the motor b earings.

Abstract: An airport map display system (10) provides situational awareness to a pilot of an airport's runways, taxiways, and other features relative to the pilot's aircraft. Data representative of an airport map is translated and communicated between aircraft systems using a data interchange method that facilitates efficient throughput of information used to represent an airport map. In addition, data representative of taxi routes, modified taxi routes, and current position of the aircraft at the airport are also translated and communicated using a compact data interchange method. Airport map data is scaled so that it is compatible with display systems previously incompatible with displaying some airport maps. Aircraft equipped with raster displays are manipulated to display map symbology by redefining existing vector group labels. For retrofit applications, the airport map display system (10) is activated when a preexisting input (e.g., an "ARPT" button) is activated when a taxi-related page is active.
