Abstract: A drive-sense circuit module includes at least one regulated source circuit coupled to a load, and to a loop correction circuit. The regulated source circuit generates a drive signal, which has a regulated characteristic and a controlled characteristic. At least one reference circuit applies a reference signal to the loop correction circuit that establishes a reference value of the controlled characteristic. The loop correction circuit senses an effect of one or more load characteristics on a sensed value of the controlled characteristic of the drive signal and generates a comparison signal based on the sensed value and the reference value of the controlled characteristic. A regulation signal is generated based on the comparison signal and used to regulate the regulated characteristic of the drive signal.

Abstract: A pneumo-mechanical landing gear deployment system includes a dual-stage handle operatively connected to a pressurized tank, a nose landing gear pneumatically connected to the pressurized tank, and a main landing gear pneumatically connected to the pressurized tank. Actuation of the dual-stage handle to a first position opens the pressurized tank thereby deploying the nose landing gear. Actuation of the dual-stage handle to a second position causes further opening of the pressurized tank thereby deploying the main landing gear. The system may be employed as a backup landing gear deployment system in the case of a primary landing gear system failure.
