7 results about "Fly-by-wire" patented technology

Fly-by-wire vehicle systems and related user interface devices are provided for controlling operation of a vehicle, such as an aircraft. An exemplary user interface includes a first linkage and a second linkage coupled to the first linkage. The first linkage is actuatable about a first pivot point and the second linkage is actuatable about a second pivot point independent of actuation of the first linkage about the first pivot point. The user interface includes a sensing arrangement configurable to obtain a first orientation of the first linkage with respect to a first reference orientation associated with the first pivot point, obtain a second orientation of the second linkage with respect to a second reference orientation associated with the second pivot point, and determine an input command based at least in part on the first orientation and the second orientation.

Disclosed is a method 100 for controlling an active linear throttle assembly 300. The method comprises receiving parameter data from a parameter sensing mechanism for a linearly moveable grip, using this data to predict expected control data based on a haptic feedback model and outputting control data based on the expected control data and actual control data to control an actuator. The actuator may be a linear actuator mechanism of the active linear throttle assembly. The method may be used in controlling the powerplant of an aircraft using a fly by wire control system. The parameter data may be the force applied to the grip or the position of the grip. Also disclosed is an associated controller and active linear throttle assembly.

A fly-by-wire system that lets a single-engine aircraft mimic multi-engine behavior for real-flight pilot training, especially asymmetric thrust effects that create yaw / roll. A cockpit central thrust control with two independent thrust levers generates an overall power command plus a dissymmetry signal; a calculator applying a dedicated control law converts these into corrected setpoints for the rudder, left / right ailerons, and propeller parameters to reproduce multi-engine handling. Instructors may trigger a simulated engine failure and then reset back to normal single-engine operation. Optional wingtip electric thrusters powered by a battery may increase asymmetric effects while maintaining safety margin, and the system may display / record simulated multi-engine data for debriefing—reducing training cost and CO2 versus operating real twins

A fly-by-wire (FBW) system comprising a plurality of servo actuators for controlling the flight control surfaces of an aircraft in which each of the servo actuators may comprise a flight control computer (FCC) that controls the output of the servo actuator. Input from a pilot or autopilot system may be communicated directly to the servo actuator FCCs, which may perform the requisite computations to determine the servo actuator output. For each axis, a primary and a secondary servo actuator may be provided, and the secondary servo actuator may operate in the event of a failure in the primary servo actuator. Each servo actuator may have two motors, each configured to drive an end of a differential such that each motor can act as a brake, a clutch or motor on the servo actuator.

Disclosed is a method for controlling an active throttle assembly. The method comprises receiving parameter data from a parameter sensing mechanism which may be configured to measure one of the position, velocity or force applied to a linearly moveable grip. The parameter is used to determine the linear movement of the grip and a transducer is used to convert this to a current value. The method then outputs control data based on the current value to a linear actuator associated with a carriage of the moveable grip. The method may be used to provide haptic feedback to a user of the active linear throttle assembly to indicate an operating condition of an engine of a vehicle containing the active throttle assembly and may be used as part of an aircraft fly by wire system.

An atherectomy system includes a user interface that an operator engages with in order to indicate requested movement of a drive assembly. One or more sensors are adapted to ascertain one or more conditions of the drive assembly and to output one or more condition signals to a controller that is operably coupled with the operator assembly and the drive assembly. The controller is adapted to receive the request signal from the operator assembly and the one or more condition signals, to determine a command signal in response to the received request signal and the received one or more condition signals, and provide the command signal to the drive assembly. The drive assembly is adapted to move relative to the advancer assembly in accordance with the command signal.
