An optoelectronic transceiver comprises an active linear TOSA circuit mounted on a header. The active linear TOSA circuit includes input nodes for receiving a differential signal pair, a first bipolar transistor, a second bipolar transistor and an electro-optical transducer. A base terminal of the first bipolar transistor is coupled to the two input nodes and an emitter terminal of the first bipolar transistor is coupled to a base terminal of the second bipolar transistor. A collector terminal of the first bipolar transistor is coupled to a first terminal of the electro-optical transducer, the first terminal of the electro-optical transducer also being configured to be coupled to a voltage source. A collector terminal of the second bipolar transistor is coupled to a second terminal of the electro-optical transducer and an emitter terminal of the second bipolar transistor is coupled to a signal ground which is not the header ground.

An actuator receives an input torque command and rotates an aeronautical surface within a prescribed range of motion. An output shaft is rigidly secured to the aeronautical surface, such that axial rotation of the output shaft results in displacement of the aeronautical surface. A drive motor controls rotation of the output shaft by applying a motive force thereto. A drive circuit controls the drive motor, to thereby control axial rotation of the output shaft, in response to keep input torque command. A torque sensor is operatively coupled to the drive shaft. The torque sensor measures output shaft rotational torque and provides an electronic representation of the output shaft rotational torque to the drive circuit. The drive circuit receives the electronic representation as a torque command feedback signal, and derives a torque error command as the difference between the input torque command and the output shaft rotational torque. When the aeronautical surface is within the range of motion, the drive circuit rotates the output shaft to compensate for the torque error command.

A nebulizer and heater system for delivering a heated aerosol spray to a patient. The nebulizer includes a nebulization chamber where an aerosol spray is formed and a subsequent heating chamber. Large liquid particles are collected in a well formed in the heating chamber. The heater is configured such that it can easily be joined to and removed from the nebulizer. The heater has a heating rod which extends into the well and heats the liquid collected therein. The heated liquid, in turn, heats the aerosol as it passes through the heating chamber.
