ST:TNG Transporter Pattern Enhancers

A pattern enhancer, also known as a transporter / transport enhancer, was a piece of portable equipment that boosted the signal of the transporter in conditions where a signal was otherwise difficult to maintain.  Pattern enhancers were about one meter in height, composed of four sections: a trio of legs which were encased within the body while not in use, highly-polished silver-colored main body casing, a black control cuff, and roughly conical top which glowed when activated and in-use.

Used in sets of three, the enhancers were set up in a triangular formation, approximately one-to-seven meters apart. First the legs were extended by means of a switch on the main body, enabling steady placement regardless of terrain. Second, the conical top and the attached control cuff of the device were rotated approximately 70-90° clockwise; once the top was lit, the enhancer was active.
