Abstract: An actuator for use with an external controller, either alone or in a group including other actuators controlled from the same external controller. The actuator includes a housing for encasing internal components of the device; a motor assembly for creating motion, the motor assembly being disposed within the housing; and a drive assembly for driving a pushrod, the drive assembly being arranged within the housing and slidingly connected to the motor assembly. A remote control communication circuit is electrically connected to the motor. The actuator includes an in line planetary gear and a linear position sensor. The actuator may include a hand held remote controller which utilizes tilt for proportional control, and a distributed network.

A remote control communication circuit is electrically connected to the motor. The remote control communication circuit includes a short range transmitter/receiver for paring the actuator to an external control device and a longer range transmitter/receiver for communicating operational control signals between the external control device and the actuator.

Abstract: A changeable portable, solar powered message sign is disclosed which offers reduced power consumption and enhanced visibility to intended observers especially during the difficult hours about dawn and dusk. The system features character matrices and two independent types of pixel defining systems. The system also includes an automatic solar tracking and control system.
