Abstract: A system for monitoring brain activity of a subject, including an implantable measurement device including: a sensor configured to measure electrical activity in the brain; electronic measurement processing devices configured to: receive measurement data from the sensor; use the measurement data to determine if the brain activity of the subject is indicative of an event; and generate event data indicative of the brain activity associated with the event; and an implantable transceiver configured to transmit the event data; an inductive implantable coil configured to inductively receive power; and an external monitoring device including: an external transceiver configured to receive event data from the implantable measurement device; an inductive external coil configured to inductively transmit power to the implantable measurement device; and electronic monitoring processing devices configured to: generate subject data; and transfer the subject data to analysis processing devices for analysis.

Abstract: Introduced is an active shield method providing security to a security critical integrated circuit against some physical attacks like probing, manipulation and modification, while providing the ability to detect any physical modification made on the active shield itself. Electrically controllable switching circuits are used to construct the upper layer conductive bit lines with electrically selectable different interconnection configurations. These bit lines arranged in a shielding pattern are used to carry a test data between a transmitter circuitry and a number of receiver circuitries which verify the integrity of the shielding lines to provide the security for the integrated circuit. By changing the selected interconnection configuration of the bit lines with a select signal produced by the transmitter, the self detection ability of the proposed active shield is provided as a countermeasure against the vulnerability to physical modification made on the active shield itself.
