Abstract

An apparatus includes a ping detection module that detects a ping signal transmitted from a secondary pad to a primary pad. The secondary pad is located on a mobile device and the primary pad is located on a stationary wireless power transfer ('WPT') device. The stationary WPT device transmits power through the primary pad to the secondary pad of the mobile device during a wireless power transfer operation. The apparatus includes a signal strength module that determines a signal strength of the ping signal received at the primary pad, and an alignment module that determines an amount of alignment of the secondary pad with respect to the primary pad based on the determined signal strength of the received ping signal.
