Method and shielding units for inductive energy coils
View Patent ↗The invention relates to protecting metals and components from inductive energy. The protecting apparatus comprises an inductive energy coil ( 51 ), a first shielding unit comprising an opening ( 58 ) around the inductive energy coil ( 51 ) wherein the first shielding unit ( 54 ) is located in parallel to inductive energy coil ( 51 ); and a second shielding unit ( 53 ) under the inductive energy coil ( 51 ) so that the inductive energy coil ( 51 ) is enabled for electromagnetic radiation. The invention further relates to a method for producing the protecting apparatus and an electronic device comprising the protecting apparatus.
1. An apparatus comprising:
an inductive energy coil configured for inductive energy transfer;
a first shielding unit comprising an opening through the first shielding unit, wherein the first shielding unit is located in parallel to the inductive energy coil, and wherein the opening through the first shielding unit is arranged to be located so that the opening at least partially reveals the inductive energy coil electromagnetic radiation wherein a transmission or reception of the inductive energy coil electromagnetic radiation is enabled through the opening and is blocked by portions of the first shielding unit surrounding the opening, said opening allowing the electromagnetic radiation to be transmitted to or received from another inductive energy device; and
a second shielding unit, wherein the second shielding unit is located in parallel to the inductive energy coil so that the inductive energy coil is enabled for transmission or reception of electromagnetic radiation.
2. The apparatus according to claim 1 , wherein the inductive energy coil is an inductive energy receiver coil.
