The solar power “invention relates to portable electronic devices having multiple power interfaces,” Purcher reports. “As a theft prevention system for protecting a portable electronic device, one embodiment of the invention comprises an acceleration sensor, an audio output device, and a controller operatively connected with the acceleration sensor and the audio output device, the acceleration sensor, the audio output, and the controller each being proximate to the portable electronic device. The acceleration sensor is configured to sense an acceleration of the portable electronic device and provide an acceleration signal to the controller upon detection of the acceleration. The controller is configured to initiate the production of an alarm signal from the audio output based on the acceleration signal.”
