Abstract: There are described methods and systems for operating an aircraft having two or more engines. One method comprises operating the two or more engines of the aircraft in an asymmetric operating regime, wherein a first of the engines is in an active mode to provide motive power to the aircraft and a second of the engines is in a standby mode to provide substantially no motive power to the aircraft; governing the first engine in the active mode using a first governing logic; and governing the second engine in the standby mode using a second governing logic, the second governing logic based on a target compressor speed and variable geometry mechanism (VGM) settings that are adjusted using trim values dependent on at least one parameter of the second engine in the standby mode.

Abstract: There is provided a data access method and system for an aircraft. Password data is obtained for use in providing access to aviation data collected by at least one data acquisition device from one or more locations in the aircraft. The password data is caused to be rendered on at least one display provided in at least one secured location of the aircraft. Subsequent to the password data being rendered on the at least one display, input data is received from at least one user device requesting access to the aviation data. The input data is compared to the password data and, when the input data matches the password data, a connection is established between the at least one user device and the at least one data acquisition device for providing the at least one user device access to the aviation data.

Abstract: A data transmission system and method for an engine of an aircraft. Engine fault data indicative of at least one fault condition of the engine is obtained at a computing device provided on-board the aircraft. Sensor data associated with the at least one fault condition is retrieved based on the engine fault data. The engine fault data and the sensor data are transmitted, through a wireless connection, to an electronic device external to the aircraft.

Abstract: A communication system and a method for transmitting data from an aircraft, the aircraft comprising at least one engine. A data collection and transmission unit is configured to collect and transmit data received from one or more locations in the aircraft, the data collection and transmission unit comprising at least one radio transmitter. At least one engine controller for the at least one engine is communicatively coupled to the data collection and transmission unit and configured to transmit, while the aircraft is airborne, engine data to the data collection and transmission unit, and, responsive to determining that the aircraft is on ground, cause the at least one radio transmitter to activate for transmitting the engine data from the data collection and transmission unit to at least one ground equipment.

Abstract: A system and method for transmitting data from an aircraft, the aircraft comprising at least one engine. Aircraft input indicative of a request to enable a maintenance mode of operation of at least one engine controller for the at least one engine is received at the at least one engine controller.

Abstract: In certain embodiments, an input device includes a chassis and a depressible actuator disposed on the chassis that, when depressed, generates and sends a control signal to a processor, where the actuator is coupleable to a removable button cover that provides user-access to activate the actuator, and a removable blank cover to prevent user access to activate the actuator. The button cover and blank cover can be separate from the chassis and may directly attach to the actuator. The input device can further include a second depressible actuator disposed on the chassis that, when depressed, generates and sends a second control signal to the processor, where the second actuator is coupleable to the button cover and the blank cover.

Abstract: In some embodiments a transceiver is configured to wirelessly transfer data between a host computing device and one or more peripheral devices over a communication path using a communication data construct comprising a packet structure arranged in a repetitive communication structure. The repetitive communication structure can include a transmit time window within which the host transmits data to the one or more connected peripheral devices and a receive time window within which the host receives data from the one or more connected peripheral devices. A duration of the receive time window is set based on a predetermined communication report rate between the host computing device and the one or more connected peripheral devices. A new peripheral device is added as a connected peripheral device when the new peripheral device transmits a request to the host to be added as a connected peripheral device and the receive time window has time available to add the new peripheral device.

Abstract: An input device including a housing and a depressible key plate disposed thereon. The key plate includes a front user-accessible portion, a pivot support portion, and a rear portion. A shaft is disposed in the pivot support portion, where the key plate rotates with respect to the shaft. A force sensor is disposed in the housing and in contact with a bottom surface of the front portion of the key plate, and activates in response to receiving a predetermined force by the bottom surface of the front portion of the key plate. The depressible key plate depresses in response to receiving a predetermined depression force on the top surface. A biasing mechanism is disposed in the housing and in contact with the bottom surface of the rear portion of the key plate to provide an upward force tuned to be substantially equal to the predetermined depression force.

Abstract: The invention relates to a dynamic cervical disk prosthesis (1) comprising two upper (11) and lower (12) rigid plates containing a viscoelastic element (10), said upper and lower plates (11 and 12) having a slightly cambered and striated contact face, the main characteristic of this invention being that the lower plate (12) is in the form of a housing, compatible with a twist-lock of the upper plate (11) while allowing the mobility and damping of the two plates (11 and 12) around the viscoelastic element (10) that can be freely distorted thereby avoiding all risk of detachment of the prosthesis when subjected to applied forces.
