Abstract:
What is described is a tire pressure sensor for use in a wheel of aircraft landing gear. The tire pressure sensor includes a position sensor configured to detect a movement of the wheel and generate a wheel movement signal based on the movement. The tire pressure sensor also includes a processor coupled to the position sensor. The processor is configured to receive the wheel movement signal, determine a wheel rotational speed of the wheel based on the wheel movement signal and generate a wheel rotational speed signal based on the wheel rotational speed.
Abstract:
A handheld interrogation device includes a controller configured to generate a power signal. The controller is also configured to determine tire pressure data based on a signal received from a tire pressure sensor. The handheld interrogation device also includes a primary coil coupled to the handheld interrogation device and configured to transmit the power signal to a sensor coil of the tire pressure sensor and to receive a data signal from the sensor coil, via inductive coupling, in response to the primary coil being within a predetermined distance of the sensor coil.
Abstract:
A tire pressure observation method and computer readable medium is provided. Upon detection of an abnormal pressure condition, a tire pressure observation method provides for various maintenance actions. A computer readable medium may contain instructions for a tire pressure observation controller directing the controller to present messages at different stages of the maintenance actions to assist maintenance staff in properly performing the maintenance actions, for example, observing the tire pressure.
Abstract:
The EMA may comprise an EMA housing, a strain gauge coupled to the EMA housing, the strain gauge comprising a Wheatstone bridge, the Wheatstone bridge comprising a first group of resistors coupled in parallel with a second group of resistors, a controller coupled to the strain gauge, a variable resistance resistor coupled to the Wheatstone bridge, the variable resistance resistor configured to derive a temperature of the EMA housing based upon a temperature of the variable resistance resistor and configured to provide feedback to the controller, the controller adjusting a force applied by the EMA based upon the temperature of the EMA housing.
Abstract:
A wheel monitoring system comprising a wheel, a bearing mechanically coupled to the wheel, an axle mechanically coupled to the bearing, and a wheel speed transducer (WST) disposed in the axle. The WST may be configured to detect vibrations. A method of monitoring a bearing is also provided and may comprise measuring a vibration of the bearing, comparing the vibration of the bearing to a predetermined vibration, and estimating a remaining useful life of the bearing.

Abstract:
A system for measuring tire pressure on an aircraft includes a wheel with a tire pressure. A tire pressure sensor on the wheel may be configured to output an electronic measurement of the tire pressure. A transmission device may be electrically coupled to the first tire pressure sensor and configured to transmit the first electronic measurement. A hubcap may be on the first wheel with a transmission device mounted to the hubcap.
Abstract:
A connector assembly includes a first side connector and a second side connector. The first side connector includes a first protective housing, a first inductor including a first end face, and a first physical connector element. The second side connector includes a second protective housing, a second inductor including a second face, and a second physical connector element. The second physical connector element is engaged with the first physical connector element and physically connects the first side connector to the second side connector such that the first end face and the second end face are adjacent. The first inductor and the second inductor are axially spaced apart. The first inductor and the second inductor form an inductive telemetry connection between the first side connector and the second side connector.
