Abstract: A system and method for bonding a protective cover to a mobile device is disclosed. A cold cast protective cover is permanently bonded to the device and provides protection against damage from dropping, impact, exposure to electric or static discharge, and exposure to liquid, gas, and dusts. The cold cast protective cover takes the shape around all or some desired portion of the outer surface of the mobile device while still providing access to the device's user interface, including display, power and volume buttons, power charging port, memory port, speaker port, camera lens, and the like. The cold cast protective cover can, with additives, increase the safety of the device for Intrinsic Safety or Hazardous environments.

Abstract: An improved intrinsically safe mobile device is designed to reduce sparking risk and surface heating while still maintaining a form factor, processing speed, and functionality comparable to conventional mobile devices. Non-intrinsically safe electronic components are mounted on an unprotected part of a printed circuit board (PCB) contained within the mobile device and are encapsulated to reduce risk of sparking and to minimize surface heating to enable the encapsulated electronic components to be certified as intrinsically safe. The encapsulated electronic components are connected using a trace with intrinsically safe electronic components mounted on a protected part of the PCB and are connected with user interface components using FPC cabling. The trace and FPC cabling are certified as intrinsically safe using one or more protection techniques, such as through use of a resistor, a double MOSFET clamping circuit, a capacitor, a fuse, or maintaining a minimum clearance space.
