Abstract: A probe assembly for measuring the concentration of exhaust's emissions in a turbine engine. The probe assembly (10) including a first probe member (14) configured and operable to passively generate a beam of light wherein the wavelength of the beam of light is contingent upon the configuration of the first probe member. A second probe member (24) positioned in the probe assembly to receive the beam of light generated by the first probe member, the second probe member configured and operable to attenuate the light passively generated from the first probe member contingent upon the gaseous species present in the exhaust emissions (20) of the turbine engine (100).

Abstract: A wireless tire pressure and wheel speed sensing system for an aircraft is provided. The system comprises the following components.
A resonant circuit is mounted to a wheel of the aircraft for monitoring the pressure of a tire mounted to said wheel. The resonant circuit comprises a wire loop of a predetermined inductance.
An interrogating circuit is magnetically coupleable to said resonant circuit and is operative to induce magnetically a variable frequency current in the wire loop of said resonant circuit. The resonant circuit generates a corresponding variable frequency electric field in response to said induced current. The variable frequency electric field includes a resonant frequency commensurate with the pressure of said tire.
A magnetic field altering apparatus is provided for alternating the magnetic coupling between said wire loop and said interrogating circuit to cause a rate of amplitude modulations of said variable frequency electric field commensurate with said wheel speed.
A receiving circuit E-field is coupleable to said resonant circuit and operative to receive the amplitude modulated variable frequency electric field of said resonant circuit and to generate a signal representative thereof.
A first processing circuit is coupled to said receiving circuit for processing the signal to generate a pressure reading of said tire based on the resonant frequency thereof.
A second processing circuit is coupled to said receiving circuit for processing said signal to generate a wheel speed reading based on the rate of amplitude modulations thereof.
