Abstract: Disclosed is a method that includes receiving absolute wireless access point coordinates from wireless access points that define respective wireless access point positions of the wireless access points. The method includes orienting the directional antenna to orientations based on the absolute wireless access point coordinates. The method includes transmitting test signals to the respective wireless access points while the directional antenna is positioned at the orientations to generate the database entries associated with the respective wireless access point positions. The method includes orienting the directional antenna according to a first one of the database entries having a greatest likelihood to establish a first communications path between a first one of the wireless access points and the wireless endpoint. The method includes transmitting a data signal to the first one of the wireless access points with a minimum transmission power based on the database entries.

Abstract: A system for an aircraft includes an aircraft component that includes a heater routed through the aircraft component, the heater including a resistive heating element and insulation surrounding the resistive heating element. A first current flows into the resistive heating element to provide heating for the aircraft component and a second current flows out of the resistive heating element. The system further includes a first sensor configured to produce a first sensor signal representing the first current, a second sensor configured to produce a second sensor signal representing the second current, a leakage sensor configured to produce a leakage sensor signal representing a leakage current, and a signal processor configured to sample and measure the first current, the second current, and a leakage current using a high frequency sampling rate to identify the presence of electric arcing. The detection of electric arcing is used to predict future heater failure and estimate heater remaining useful life.

Abstract: An aircraft freestream data system can include a first ultrasonic air data system (UADS) configured to sense local acoustic properties at a first location on an aircraft, a first local air data module operatively connected to the first UADS and configured to determine first local air data of the first location and to output first local air data, and a freestream data module operatively connected to the first local air data module. The freestream data module can be configured to receive the first local air data from the local air data module, determine one or more freestream air data parameters based on at least the first local air data, and output the one or more freestream air data parameters to one or more aircraft consuming systems.

Abstract: A micromechanical pressure sensor for measuring a pressure differential includes a diaphragm having an inner region and two edge regions, one opposite the other with respect to the inner region. Two or more piezoresistive resistance devices are on the diaphragm, at least one in each of the inner and edge region, and are configured to be electrically connected in a bridge circuit. The micromechanical pressure sensor is configured so that an operating temperature of the one or more piezoresistive resistance devices in the inner region is substantially the same as an operating temperature of the one or more piezoresistive resistance devices in at least one of the edge regions throughout a full operating range such that an error of the micromechanical pressure sensor output resulting from self-heating is less than if the micromechanical pressure sensor were not configured to maintain the operating temperatures substantially the same.

Abstract: An angle-of-attack sensor includes at least one acoustic transmitter is configured to provide an acoustic pulse. The first acoustic receiver is positioned at a radial distance from the at least one acoustic transmitter. The first acoustic receiver is configured to receive the acoustic pulse at a first time and provide a first receiver signal. The second acoustic receiver is positioned at the radial distance from the at least one acoustic transmitter aligned with an axis that extends through the at least one acoustic transmitter and the first acoustic receiver. The second acoustic receiver is configured to receive the acoustic pulse at a second time and provide a second receiver signal. The angle-of-attack circuitry is configured to determine a delay difference between the first and second receiver signals representative of a difference between the first time and the second time and determine an angle-of-attack based upon the delay difference.
