Fail safe blocks
Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to identifying and correcting failures within wireless power systems (or any other system that is subject to design/device fault). Some embodiments monitor multiple states/control signals in a wireless power transmission system having an array of antenna. A determination can be made as to whether each of the multiple states are in an expected configuration (or make the expected transitions implying different states during normal operations). For examples, this can include identifying whether each antenna in the array of antennas is in a transmitting or receiving state. Any problems (e.g., timing problems, antennas stuck in a Tx or Rx state, controller malfunction, etc.) within the system can be detected by analyzing the multiple states/control signals and compare them against expected behavior/configuration. Some embodiments can activate a mitigation protocol and/or recovery through re-try/re-initialization/re-boot processes.
