Abstract

Techniques for locating a power transmission unit (PTU) in a system, method, and apparatus are described herein. For example, an apparatus may include a power detector to detect a low battery condition of the apparatus. The apparatus may also include a PTU locator to perform a PTU scan in response to the low battery condition, the PTU scan to identify a location of the PTU. The apparatus may also further include a PTU location displayer to display a location of the PTU based on the results of the PTU scan.
