Abstract: A current measuring device has a current conductor and a differential magnetic field sensor. The differential magnetic field sensor has a connection frame and two sensor elements, wherein the sensor elements are arranged such in relation to an edge of a straight section of the current conductor, which is parallel to a direction of current flow through the current conductor, that one of the sensor elements overlaps the current conductor in a plan view of the current conductor and the other of the sensor elements does not overlap the current conductor in a plan view of the current conductor. The current measuring device further has a device for reducing distortions which are generated in an output signal of the differential magnetic field sensor due to eddy currents in the connection frame of the magnetic field sensor.

Abstract: A circuit includes a power transistor with a first and a second load electrode and a line connected to the first or the second load electrode and configured to carry a load current that causes a magnetic field around the line. The circuit further includes a magnetic field sensor arranged adjacent to the line to sense the magnetic field and provide a current sense signal, which represents the load current. The circuit further includes a protection circuit including a comparator, a latch, and a first electronic switch, wherein the comparator is configured to signal, at its output, that the current-sense signal exceeds a first threshold value. The latch is set based on an output signal of the comparator, and the first electronic switch is coupled to a control electrode of the power transistor and configured to discharge the control electrode when the latch is set to switch the power transistor off.

Abstract: 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.

Abstract: 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.

The sensor device further includes a unit configured to provide an output signal based on a difference or a sum including the first differential signal and the second differential signal.

Abstract: 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.

Abstract: The throttleable solid propellant system includes a substantially solid propellant, a shape-altering structure, and an actuation source. The shape-altering structure is at least partially disposed within the substantially solid propellant. The actuation source is to be coupled to the shape-altering structure. The actuation source is to be configured to actuate the shape-altering structure between a first position and a second position. Transitioning the shape-altering structure between the first position and the second position may crack and/or deform the substantially solid propellant. Cracking and/or deforming the substantially solid propellant may increase the burning surface area of the propellant, thereby altering the thrust produced from the throttleable solid propellant system.
