Abstract: The present disclosure provides a method of providing quadrant information to a magnetic sensing device comprising a magnetic angle sensor, and in particular, a magnetic angle sensor configured to provide 180° absolute angle measurements, such as a 180° anisotropic magnetoresistive (AMR) angle sensor, such that the magnetic sensing device outputs an analog signal encoded with 360° information. In this respect, magnetic sensing device is provided with a magnetic angle sensor and a quadrant detector, which may be provided on the same substrate or two separate substrates, wherein the signal from the quadrant detector is encoded into the analog sine and cosine voltage outputs from the magnetic angle sensor such that the two analog outputs provide 360° angle information.

Abstract: A serial interface, such as a serial peripheral interface (SPI), with improved diagnostic coverage is disclosed. The serial interface includes a data verification module that selects an error detection value in response to a mode signal indicating if the transmitting device is in user mode or test mode. For example, the data verification module computes a cyclic redundancy check (CRC) value and selects either the computed CRC value or its inverse based on the mode. The receiving device can determine the mode of the transmitting device based on the error detection value used. The serial interface further includes a read detector for clearing the transmit data buffer after data is read out. The serial interface may further include a loopback circuit for verifying that the data output from an output pin matches the data from the transmit data buffer.

Abstract: Aspects of the present disclosure include using particles in phase change materials to track temperature change of an object. The particles may be initially disposed at specific locations within the phase change materials. As the phase change materials transition from the solid state to the fluid state, the particles may move from the initial locations to different locations. The change in locations of the particles may be detected magnetically, electrically, optically, and/or visually. Such change may indicate that the object experienced a temperate above at least one phase transition temperature of the phase change materials.
