Abstract: A method of determining a position of a first object includes receiving a first component and a second component of a vector field jointly generated by the first object and by a second object. The method further includes using the second component of the vector field to provide a compensation quantity indicating a contribution of the second object to the first component of the vector field. Further, the method includes determining the position of the first object using the first component of the vector field and the compensation quantity.

Abstract: A sensor device includes a first sensor element that generates a first sensor signal based on a varying magnetic field; a second sensor element that generates a second sensor signal based on the varying magnetic field; a signal processing circuit configured to generate a first pulsed signal based on the first sensor signal and generate a second pulsed signal based on the second sensor signal; a fault detector that detects a fault and generates an error signal indicating the fault; and an output generator that receives the error signal based on a first condition that the fault detector detects the fault, and simultaneously outputs a first output signal and a second output signal. In response to the first condition being satisfied, the output generator maintains the first output signal in a steady state and outputs the second pulsed signal as the second output signal.

Abstract: A control stick may include a magnet and a three-dimensional (3D) magnetic sensor. The 3D magnetic sensor may determine a twist angle of a handle of the control stick based on a strength of a magnetic field at the 3D magnetic sensor. A twisting of the handle may modify an air gap between the 3D magnetic sensor and the magnet. The strength of the magnetic field may be based on strengths of first, second, and third magnetic field components. The 3D magnetic sensor may determine a tilt angle of the handle based on a ratio of the strength of the first magnetic field component to the strength of the third magnetic field component. A tilting of the handle in a direction corresponding to the first magnetic field component may modify the ratio of the strength of the first magnetic field component to the strength of the third magnetic field component.

Abstract: The described techniques address deadlocking issues associated with interconnected hardware devices that share bus lines associated with a digital communication interface. A watchdog-based solution is described that may be implemented internally within the interconnected hardware devices or, alternatively, as an external component. The watchdog circuity may monitor a logic state of one or more internal connections of a hardware device and cause one or more portions of the hardware device to reset when a deadlock condition is detected using this internal monitoring.

Abstract: This disclosure is directed to techniques that may accurately determine the amount of current flowing through a power switch circuit by measuring the voltage across the inherent impedance of the circuit connections. One connection may include a low impedance connection between the power switch output and ground, where the low impedance connection may be on the order of milliohms. By using a four-wire measurement, the sensing connections are not in the current path, so the measured value may not be affected by the current. The connection that makes up the current path can be accomplished with a variety of conductive materials. Conductive materials may have a temperature coefficient of resistivity that may impact a measurement of electric current as the temperature changes. Measuring the temperature of the current path, along with the voltage across the connection, may allow a more accurate current measurement.

Abstract: A slave device may receive a clock signal from a master device via a bus. The slave device may detect a first pulse of the clock signal. The first pulse indicates that a bit is to be written to a slave shift register of the slave device. The slave device may identify a timeout threshold associated with the clock signal. The slave device may determine that the timeout threshold expired without a second pulse from the clock signal being detected. The slave device may reset, based on the timeout threshold expiring, the slave shift register to synchronize the slave shift register with a master shift register of the master device.

Abstract: A device may determine a sensor identifier corresponding to a sensor integrated circuit (IC) associated with a sensor system. The device may provide the sensor identifier corresponding to the sensor IC. The device may receive, based on providing the sensor identifier, compensation parameter information associated with the sensor IC. The device may cause a set of compensation parameters, associated with the compensation parameter information, to be stored on a controller associated with the sensor system. The set of compensation parameters may include one or more parameters associated with correcting a measurement performed by the sensor IC or a safety result provided by the sensor IC.
