Abstract: An in-line heater system on board an aircraft includes a heater element positioned within a tubing, at least one sensor positioned within the tubing configured to monitor the temperature within the tubing, and an inline heater controller configured to receive information regarding the heater element via the at least one sensor. The inline heater controller is positioned at a location spaced away from the heater element and the tubing. The inline heater controller includes a printed circuit board configured to receive the information regarding the heater element via the at least one sensor, and an aerospace connector configured to transmit the information regarding the heater element via the at least one sensor to the aircraft.

Abstract: An apparatus for controlling a waste outlet of a toilet includes a flush handle that is rotated by a user. A valve pinion arm is coupled to the flush handle and a waste discharge valve disposed at the waste outlet of the toilet is coupled to the valve pinion arm at an opposite end. The rotation of the flush handle is configured to move the valve pinion arm in a first direction. The movement of the valve pinion arm is configured to move the waste discharge valve to an open position. Upon release of the flush handle, the valve pinion arm is configured to move in a second direction and to move the waste discharge valve to a closed position. According to an embodiment, the apparatus includes an actuated flush control mechanism and a manual flush control mechanism.
