A method and system for wireless frequency division multiple access communications in the uplink andor downlink directions. The receiver is characterized in that it further comprises at least a second receiving device and a beam splitter for splitting the focused light beam partially towards the first receiving device and partially towards the at least second receiving device. The radiolucent handle is used in conjunction with a protection sleeve, trocar, drill sleeve, and drill bit, which are used to locate and drill through the hole in the nail. When power irregularities in the power input to the DC motor are detected by the control circuit, the control circuit stops generating PWM signals and stops the current provided to the DC motor.
