  • HYBRID PROPULSION SYSTEM COCKPIT INTERFACE
    Publication number: 20240166361
    Abstract: An example system includes a throttle control for managing power in a hybrid propulsion system that includes an electrical propulsion unit configured to operate using electrical energy sourced from an electrical energy storage system (ESS) and/or one or more electrical generators, the throttle control comprising: a control lever movable through a plurality of positions, the plurality of positions including: a regeneration position; an off position; a maximum electric only position; a maximum continuous dual source position; and a maximum non-continuous dual source position.

  • Systems and methods for improving bearing availability and accuracy for a tracking filter
    Patent number: 9170316
    Abstract: Systems and methods for improving bearing availability and accuracy in a traffic collision-avoidance system (TCAS). In an exemplary method, if only a single phase-difference value is received for one of two two-element antennas, a processor determines an expected maximum antenna element phase-difference value for the elements of the two-element antenna that did not receive a phase-difference value for a target signal source; estimates a phase-difference value for the two-element antenna that did not include a phase-difference value, based on the expected maximum antenna element phase-difference value and a previously determined predicted bearing value; and calculates bearing based on the estimated phase-difference value and a phase-difference value received from the other two-element antenna.
    Type: Grant
