    Abstract: An interface circuit for a bridge sensor has a switch that connects to a resistive bridge circuit. The resistive bridge circuit includes a first input terminal, a second input terminal, and a pair of resistive branches that connect between the first and second input terminals. Both of the resistive branches include an output terminal. The switch is connected to the first input terminal and is in series with both resistive branches for connecting and disconnecting a voltage source from the resistive branch output terminals.

    Abstract: Apparatus and associated methods relate to mitigating data-stream dropout in a serial data-stream. A time-sequence of messages of the serial data-stream is received, each containing a data packet communicating an action. Validity of each of the time-sequence of messages received is determined. After receiving each valid message, a plurality of future actions is created based at least in part on the valid message received. The plurality of future actions corresponds to a plurality of future data packets of the time-sequence of messages. After receiving each valid message, the action communicated in the valid message received is performed. After receiving each invalid messages, a next one of the set of sequential future actions created is instead used in place of any action communicated in the data packet of the invalid message received.

    Abstract: An aircraft control system may include an engine control subsystem, a flight control subsystem, a processor, and a tangible, non-transitory memory. The tangible, non-transitory memory may be configured to communicate with the processor, and the tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the processor, cause the aircraft control system to perform various operations. The various operations may include controlling, by the processor, the engine control subsystem and controlling, by the processor, the flight control subsystem. That is, a single processor (or a single set of processors) may control both the engine control subsystem and the flight control subsystem.

    Abstract: An electric motor assembly includes a primary electric motor including a primary rotor assembly and a primary stator assembly configured to be actuated to cause the primary rotor assembly to rotate based on an amount of magnetic flux in the rotor assembly. The assembly also includes a secondary electric motor including a secondary rotor assembly and a secondary stator assembly and a controllable magnetic device coupled to at least one of the primary rotor assembly and the secondary rotor assembly. The assembly also includes a controller configured to actuate the secondary electric motor based on a failure of the primary electric motor, and apply electric current to the controllable magnetic device to reduce back electromotive force (BEMF) caused by rotation of the primary rotor assembly during actuation of the secondary electric motor.

    Abstract: A method of controlling the behavior of a latching relay includes receiving a configuration signal of either a first behavior signal or a second behavior signal, receiving a power status signal of either a powered or unpowered signal, receiving either a low-to-high or a high-to-low signal command signal, generating latching pulse in response to receiving a powered signal input as the power status signal and a low-to-high signal as the command signal, generating an unlatching pulse in response to receiving a powered signal input as the power status signal and a high-to-low signal as the command signal input, and generating an unlatching pulse in response to receiving the second behavior signal as the configuration signal and the unpowered signal as the power status signal.

    Abstract: An embodiment of a linear motor assembly includes an armature extending linearly along an axis, the armature having a plurality of windings. The linear motor assembly also includes a magnetic assembly including a plurality of magnets arrayed in a loop configuration, a linear section of the plurality of magnets extending linearly through the plurality of windings in a direction parallel to the axis, each magnet of the linear section being oriented in the direction and configured to move in the direction due to interaction between the plurality of windings and a magnetic field generated by the magnetic assembly.

    Abstract: A machine learning system that includes one or more machine learning models implemented in one or more hardware processors, a first-level feature creation module, and a combination module provides an output based on one or more channel inputs. Each of the one or more machine learning models receives the channel inputs and additional feature inputs based on the channel inputs to produce the output. The first-level feature creation module receives the channel inputs, performs a feature creation operation, creates the additional feature inputs, and provides the additional feature inputs to at least one of the machine learning models. The first-level feature creation operation performs a calculation on one or more aspects of the channel inputs, and the combination module receives the one or more machine learning model outputs and produce a machine learning channel output.
