Abstract: A personal security system is described herein that includes a mobile electronic device and associated cover. The cover comprises a housing that defines a recess, and an alarm system is disposed within the recess. The cover further includes a triggering mechanism external to the housing, the triggering mechanism being operable to actuate the alarm system in response to user interaction therewith. The alarm system is capable of generating an audible panic alarm in response to user actuation thereof. The alarm system is also capable of wirelessly communicating with the mobile electronic device itself to cause the mobile electronic device to perform additional functions that relate to personal safety when the panic alarm system has been actuated by a user thereof.
