A reel apparatus for a moveable system comprises a base disposed on the moveable system; a rotatable drum rotatably supported on the base onto which a cable can be spooled; a speed reducer for rotating the drum; a motor drive the speed reducer; a first transmission device coupled between the motor and the speed reducer; a coupling coupled between the speed reducer and the motor, when a load of the drum exceeds a predetermined torque, the coupling slips so as to limit a drive torque transmitted from the motor to the speed reducer to stop the drum; and an electrical connector connected at one end to a power cord of the moveable system and slidably contacted with the other end thereof with one end of the cable. With the present invention, a commercial power supply can be connected to the moveable system directly, thus reducing components of the conventional power supplying apparatus. At the same time, the cable sheath is prevented from being damaging and potential safety hazards are eliminated.

For high resolution resistor string DACs, a resistor string is placed in an array of columns and rows, each resistor tap is connected to a switch network, and a decoder is used to select switches to be closed such that sub-DAC voltage comes from the resistor taps connected to the selected switches. The voltages from each row of the resistor string are fed into a multiplexer, wherein the multiplexer produces an output voltage. A method and apparatus are disclosed for implementing the reflective nature of Gray code to design a DAC such that all the switches in a column of the resistor string may be controlled with only one control signal, thereby reducing extra routing costs, surface area, and dynamic power consumed by the circuit.
