Temperature-indicating mobile device case

Abstract

The temperature indicating mobile device case is configured for use with a personal data device. The temperature indicating mobile device case comprises a PDD shell and a control circuit. The control circuit mounts in the PDD shell. The PDD shell is a protective structure that contains the personal data device such that the personal data device is operable while contained in the PDD shell. The control circuit monitors the exterior surface temperature of the personal data device when the personal data device is stored in the PDD shell. The control circuit generates a first visible indication when the measured temperature of the personal data device is above a previously determined threshold temperature. The control circuit generates a second visible indication when the measured temperature of the personal data device is below the previously determined threshold temperature.
