  • Magnetic field sensor and related techniques that provide an angle correction module
    Patent number: 9400164
    Abstract: A magnetic field sensor provides an angle error value to correct errors of the magnetic field sensor. The angle error value is a function of temperature and magnetic field strength and is used to correct a measured magnetic field angle. Associated methods are also described.

  • Signaling Between Master and Slave Components Using a Shared Communication Node of the Master Component
    Publication number: 20150236869
    Abstract: A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may include an address to identify the network slave device on the network. It may also include a communication circuit configured to process a command received by the transceiver and generate a reply for transmission over the communication bus if an address included in the command matches the address of the slave device. A master device communicating on the network may send commands including the address of the slave device in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.

    Publication number: 20150236746
    Abstract: A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may have an address to identify the network slave device on the network. It may also have a communication circuit configured to process a series of commands received by the transceiver and respond to a command if a position of the command in the series of commands corresponds to the address of the network slave device. A master device communicating on the network may send the series of command in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.
