  • Patent number: 11263322
    Abstract: A redundancy system includes a first computational device and a second computational device each configured to receive at least one input and to generate a first output and a second output, respectively, based on the at least one input; a random sequence generator configured to generate a random bit sequence; a random delay selector configured to determine a random delay based on the random bit sequence; a first random delay circuit configured to delay outputting the at least one input to the first computational device based on the random delay; a second random delay circuit configured to delay outputting the second output based on the random delay; and a fault detection circuit configured to receive the first output and the delayed second output, and to generate a comparison result based on comparing the first input to the delayed second output.

  • Patent number: 11227072
    Abstract: The present disclosure relates to a security device, a system, and a method for securing a control apparatus. The security device includes a data security unit which is configured to secure data, data communication and information, and includes a first security component inside the data security unit to operate in a first operating mode, and at least one first monitoring unit to operate in a high-availability mode which, said first monitoring unit being configured to detect a fault present in the first security component. The high-availability mode is different from the first operating mode. The security device further includes a second security component which is configured to operate in the high-availability mode and to output a first response signal if a fault is detected by the first monitoring, where the high-availability mode is available independently from the first operating mode.

  • Patent number: 10467889
    Abstract: In various embodiments, an alarm handling circuitry is provided. The alarm handling circuitry may include a first alarm processing circuit configured to process a first received alarm and to provide a first processed alarm response signal, a second alarm processing circuit configured to process a second received alarm and to provide a second processed alarm response signal, and an interface between the first alarm processing circuit and the second alarm processing circuit configured to input an alive indication signal from the first alarm processing circuit to the second alarm processing circuit indicating whether the first alarm processing circuit is operating.
