The multi-frequency antenna transmission, including a drive gear, a gear train with parallel gear shafts, screw assemblies and a shifter. The transmission gears are connected to the stoppers of the screw assemblies one by one, the drive gear drives the various transmission gears to rotate, and all the stoppers rotate. The shifter pushes the stopper of one of the screw assemblies, such that the first elastic member disposed between the connection member and the stopper is compressed, and the connection member is connected to corresponding lead screw, thus the power of the stopper is transmitted to corresponding lead screw through the compressed first elastic member and the connection member, and drives the lead screw to rotate.

The present disclosure relates to a robotic arm comprising a first arm unit, a second arm unit, a third arm unit, a first drive system, a second drive system and a third drive system. The first arm unit is connected to the second arm unit, and the second arm unit is connected to the third arm unit. The first, second and third drive systems cause the second arm unit to move relative to the first arm unit and cause the third arm unit to move relative to the second arm unit.

Systems and methods are disclosed herein for an aircraft seat with a dual-function linear actuator. The linear actuator may activate a first adjustable feature by moving in a first direction, and the linear actuator may activate a second adjustable feature by moving in a second direction. The linear actuator may include a decoupling mechanism. The decoupling mechanism may decouple the first adjustable feature and the second adjustable feature from the linear actuator in response to loss of power to the linear actuator.

An adjusting mechanism is disclosed. The adjusting mechanism has a differential, first and second stepping motors engaging with the differential, a screw rod connected to the output shaft of the differential such that the screw rod rotates along with the rotation of the output shaft, and a moving block threadably connected to the screw rod to permit motion of the moving block along the longitudinal axis of the screw rod. The output shaft of the adjusting mechanism rotates according to the rotation of the first and second stepping motors, so as to drive the movement of the moving block along the screw rod.
