Abstract
A case for an electronic device includes a housing for enclosing the electronic device and a removable heating device that may be placed in or on the housing for warming the electronic device without electricity from the electronic device. The removable heating device includes a pouch enclosing a supersaturated solution and a metal disk. The super saturated solution in the pouch undergoes an exothermic reaction when the disk is actuated.
Claims16
A case for an electronic device, the case comprising:
- a housing for at least partially enclosing the electronic device;
- a removable heating device configured to be placed in or on the housing for warming the electronic device without electricity from the electronic device, the heating device including a pouch enclosing a metal disk and a chemical that generates heat via an exothermic reaction when the metal disk is actuated;
- and
- a control device configured to actuate the metal disk upon receiving a triggering signal from the electronic device, the control device including an electrically-activated plunger operable to push against the metal disk.
A case for an electronic device, the case comprising:
- a housing for enclosing the electronic device, the housing including a back plate having an inner wall, an outer wall, and a recessed region;
- and
- a circumscribing sidewall extending generally perpendicularly from the back plate to define a chamber for receiving the electronic device;
- a removable heating device configured to be placed in the recessed region of the back plate for warming the electronic device without electricity from the electronic device, the heating device including a pouch enclosing a metal disk and a chemical that generates heat via an exothermic reaction when the metal disk is actuated;
- and
- a control device that actuates the metal disk upon receiving a triggering signal from the electronic device, the control device including an electrically-activated plunger for actuating the metal disk.
A case for an electronic device, the case comprising:
- a housing for enclosing the electronic device, the housing including a back plate having an inner wall, an outer wall, and a recessed region, the inner wall being at least partially formed of a heat conductive material for conducting heat to the electronic device, the outer wall being at least partially formed of an insulating material so as to minimize heat loss from the protective case;
- and
- a circumscribing sidewall extending generally perpendicularly from the back plate to define a chamber for receiving the electronic device, the sidewall including a plurality of cut-outs for providing access to components of the electronic device;
- a removable heating device configured to be placed in the recessed region of the back plate for warming the electronic device without electricity from the electronic device, the heating device including a pouch enclosing a metal disk and a chemical that generates heat via an exothermic reaction when the metal disk is actuated;
- and
- a control device having an electrically-activated plunger configured to actuate the metal disk upon the control device receiving a triggering signal from the electronic device, the metal disk being additionally actuatable via a user pressing the outer wall of the back plate of the housing.
