Abstract: The invention relates to an arrangement and a method performing data exchange between various integrated circuits, IC, (3,4,5,6,7) in an automotive control system wherein the data are exchanged by a bus and has the object to enable ASIL C/D system coverage and to tie various ICs (clocks, regulators, memory interfaces, sensor signal conditioners, power management ICs etc.) This is solved the data are exchanged by a bus being ASIL C/D compliant and forming a common protocol to exchange information among the integrated circuits (3,4,5,6,7). The method is solved by functions implemented within the bus as setting the frequency of operation; arbitrating roles of the integrated circuits as master or slave device; checking integrity of exchanged data; frame repetition; detecting bus stuck-at failure modes; filtering or denouncing failures and warnings from peripheral devices; detecting remote out of specification local clock; and monitoring and predicting system reliability and profiling maintenance events.

Abstract: An apparatus includes a plurality of registers and a host interface comprising a plurality of pins. One of the plurality of registers may be a power state entry register configured to control entry to a low power state. One of the plurality of pins may be an enable pin. The apparatus may be configured to enter the low power state in response to setting the power state entry register to a first value and providing the enable pin a signal with a first level. The apparatus may be configured to exit the low power state in response to providing the enable pin the signal with a second level. The apparatus may enter an idle state after exiting the low power state. The low power state may consume less power than the idle state. The enable pin is implemented as an input configured to control a status of a plurality of regulators.

Abstract: An accurate position sensor is presented. The sensor operates over 360-degree motion angular motion and includes a coil structure formed on a substrate and a target mounted to be angularly moved over the coil structure, the target being formed of a conducting material in a shape of a spiral of Archimedes. The coil structure includes coils with an arc sufficient to operate over a 360 degree motion of the target, for example between 120 degrees and 360 degrees. Some embodiments include coils with a 180 degree arc. A method of operating the position sensor includes rotating a target formed of a conducting material in a shape of a spiral of Archimedes over a coil structure and providing a linearized and calibrated response indicating the angular position of the target relative to the coil structure.

Abstract: In a wireless power transfer operation, the operating parameters are adjusted to improve efficiency by reducing the transmit and receive coil currents as follows. First, the transmitter causes the receiver to reduce the receive coil current to the lowest value based on the transmitter/receiver communication while still delivering the same amount of power to the load as before the AC current was adjusted to the minimum value. Then the transmitter may change the operating parameters to increase or preserve the power provided to the receiver without decreasing efficiency or with only small decrease in efficiency, or with increasing the efficiency. For example, the transmitter may increase the VBRG voltage (the DC voltage powering the transmit coil) or the operating frequency to maintain or increase output power levels at lower or the same AC and DC current levels. Other features are also provided.

Abstract: An apparatus includes a transmit-receive switch circuit and a detector circuit. The transmit-receive switch circuit may be connected between an input port, an output port, and a common port, and configured to switch a transmit radio-frequency signal from the input port to the common port in a transmit mode and a receive radio-frequency signal from the common port to the output port in a receive mode. The detector circuit may be integrated within the transmit-receive switch and may be configured to generate a power detection signal in response to at least one of the transmit radio-frequency signal or the receive radio-frequency signal.
