Abstract

A device is provided for use by a user, wherein the device includes a first sensor, a second sensor and an efficiency generating component. The first sensor detects a first parameter and generates a first detected signal based on the first detected parameter. The second sensor detects a second parameter and generates a second detected signal based on the second detected parameter. The efficiency generating component generates an efficiency signal based on the first detected signal and the second detected signal.
