The present invention discloses an architecture of an embedded internet robot system controlled by brain waves, wherein the brain-computer interface and the internet robot system cooperate with the alertness level detection technology and the instruction translation technology, and thereby, the user can control a distal-end robot purely via consciousness activities and can interact with the environment as if there were an entity representing the user's consciousness appearing in the distal end. The seriously disabled person can regain his expressive ability via the present invention. Further, the present invention can also be applied to a multi-player interactive game system.

A self-compensation method includes: firstly using a min-sum algorithm to derive multiple output values in order to approach a operational result of the checking side of a belief-propagation; and then checking the present iteration number of decoding based on a checking rule; and finally, if in the previous step the present iteration number is identified with a to-be-corrected state, then performing a compensation procedure on the multiple output values, wherein the compensation term is dynamically selected in accordance with an input value of the checking nodes of the belief-propagation. The invention also provides an automatic compensation apparatus, which consists of devices such as a min-sum operating unit, and a dynamic quantization control unit, etc., which can be used, while executing the invented method described above, to decode the belief-propagation algorithm.

A transient detection circuit coupled between a first power line and a second power line and including a first control unit, a setting unit, and a voltage regulation unit. The first control unit generates a first control signal. The first control signal is at a first level when an electrostatic discharge (ESD) event occurs. The first control signal is at a second level when the ESD event does not occur. The setting unit sets a first node. The first node is set at the second level when the first control signal is at the first level. The voltage regulation unit regulates the first node. The voltage regulation unit regulates the level of the first node at the second level when the first control signal is at the second level.

A transient detection circuit including a detecting unit, a setting unit, and a memory unit. The transient detection circuit provides an information signal to an external instrument when an electrostatic discharge (ESD) event occurs. The detecting unit is coupled between a first power line and a second power line for detecting the ESD event. The setting unit sets a level of a first node according to the detection result. The memory unit controls the information signal according to the level of the first node. The information signal is at a first level when the ESD event occurs in the first power line.
