DEFINITION

Classification: 361/816

Shielding:

(under subclass 679) Subject matter wherein the electronic systems and devices are provided: (a) With means for protecting at least part of the devices from external electric or magnetic fields; (b) with means to protect one or more elements of the device from electric or magnetic fields generated in one or more other parts of the system; or (c) with protecting or screening means to prevent radiation of undesired electric or magnetic fields generated within the system.
