20 Claims

1. A device comprising:

a communication unit, comprising at least one of an antenna, hardware, firmware, and software, for establishing external communication in relation to the device, the communication unit operable with a master controller via a communication link;

a microcontroller;

a memory; and

a communication controller configured as an island activable by a user interaction, the island hardware having an island control;

wherein the island control is a pass-through system;

wherein the pass-through system can only communicate in one direction at a time, either to the master controller or the microcontroller; and

wherein the direction of communication is only controlled by the microcontroller, and

wherein the master controller cannot control the direction of communication; and

wherein the island is automatically deactivated in the absence of a user interaction; and

wherein the antenna of the communication unit is configured to harvest energy to power the device.
