Abstract: An electronic device can include a motor that rotates a shaft that is coupled to a gear. A belt or a chain can be placed in contract with the gear and other rotational devices. For optimum performance, the chain or chain should be adjusted to an optimum tension. The tension can be adjusted by moving the motor and securing the motor in a position the provided the optimum tension. Alternatively, the motor can be in a fixed rigid position and an idler pulley in contact with the belt or chain can be positioned to provide the optimum tension.

Abstract: A clamp device is used to releasably secure an electronic device to a mounting base. The electronic device includes a mounting surface and electrical components. The electronic device is placed in physical contact with the clamp device and a toggle clam is actuated to secure the electronic device to the mounting base. An electrical coupling can also be connected when the toggle clamp secures the electronic device to the base. A safety level is actuated automatically when the lever secures the electronic device to prevent the toggle clamp from being accidentally released. The safety lever is released before the toggle clamp is released to remove the electronic device from the base which also disconnects the electrical coupling.

Abstract: A positioning device is used to accurately position payload devices coupled to the positioning device. The positioning device includes a housing, a tilt shaft that extends through one side or two sides of the housing. The payloads are coupled to the exposed ends of the tilt shaft and a tilt bearing is mounted between the tilt shaft and the housing. The tilt shaft position is controlled by a tilt motor that engages a toothed tilt belt to rotate the tilt shaft bearing. A pan bearing is mounted between the housing and a pan shaft. The rotational position of the housing is controlled by a pan motor which engages a toothed pan belt to rotate the housing. By controlling the pan and tilt, the payloads can be accurately moved to any rotational position.
