In some implementations, a sensor may determine a delay latency value associated with an amount of time from completion of a set of sensor tasks to an actual time of reception of a trigger to selectively transmit or sample sensor data. The sensor may calculate a deviation of the delay latency value from a target delay latency. The sensor may transmit a data frame including an indication associated with the deviation of the delay latency value from the target delay latency.

Adaptation to a pulse width modulation frequency variation for a sensor operating in a synchronous mode

A off-axis angle sensor may receive a set of output signals including a first output signal, a second output signal, and a third output signal. The off-axis angle sensor may determine, based on the set of output signals, a set of delta signals including a first delta signal, a second delta signal, and a third delta signal. The off-axis angle sensor may identify a set of functional safety checks, from a plurality of functional safety checks configured on the off-axis angle sensor, for selective performance in association with determining functional safety of the off-axis angle sensor. Each of the plurality of functional safety checks may be performed independently of each of the other functional safety checks. The off-axis angle sensor may perform one or more functional safety checks based at least in part on at least one of: the set of output signals or the set of delta signals.

Multilayered safety mechanism for a three-phase off-axis angle sensor

A method and slave devices are disclosed in which an address assignment to slave devices takes place with the aid of a collision detection. The slave device receives an initialization signal, transmits an identifier over a bus in response to the initialization signal, checks whether a collision occurs on the bus when transmitting the identifier, and if a collision occurs, places the slave device into an inactive state, and if no collision occurs, receives an address for the slave device after the transmission of the identifier.

Slave device, bus system, and methods

A motor drive circuit provides a drive signal to an electronically commutated motor. A control circuit the motor drive circuit based on calibration data. The calibration data indicate a relationship between an actual angular position of a rotor of the motor in response to the drive signal and an expected angular position of a rotor of an ideal motor in response to the drive signal.
