  • Patent number: 10911086
    Abstract: A receiver according to an embodiment includes a receiver circuit to receive a transition in a first direction, a second transition after the first transition in a second direction, and a third transition after the second transition in the first direction and a fourth transition in the second direction of a signal. The receiver circuit is adapted to determine a first time period between the first and third transitions and to determine a second time period between the second and fourth transitions. The receiver circuit is adapted to determine a datum based on at least one of the first time period and the second time period. Furthermore, the receiver is adapted to indicate an error, if the determined first and second time periods do not fulfil a predetermined verification relationship.

  • Patent number: 10565088
    Abstract: According to some possible implementations, a monitoring device may receive a set of inputs from one or more drivers of a device connected to a bus. The one or more drivers may be capable of driving a bus line of the bus, and the bus may connect multiple devices capable of driving the bus line. The monitoring device may determine a length of time over which the set of inputs maintains a value indicating that the bus is not idle. The monitoring device may compare the length of time and a threshold. The monitoring device may output a signal based on comparing the length of time and the threshold.
