Embodiments of the present disclosure are a FinFET device, and methods of forming a FinFET device. A drill string-mounted running tool is used to selectively engage the wear bushing during emplacement and removal. The gateway antenna radiates downlink RF signals into and receives uplink RF signals from, the enclosed environment, respectively. The first switch and the second switch may be turned on or off based on the detected temperature of the head or ink in the head.
