A magnetic sensor package comprising a magnetic multi-turn sensor die and a magnetic single turn sensor die, in which both sensor dies are packaged on the same lead frame. A method of manufacturing the magnetic sensor package is also provided. A magnetic sensor system comprising a rotating magnet and the magnetic sensor package, where the sensor package is arranged so that both sensor dies sit within a homogenous magnetic field, thereby ensuring that the output signal of each sensor is not corrupted by any stray fields.

Magnetic sensor package and magnetic sensing system

Magnetic sensor package

A system includes a multiturn counter that can store a magnetic state associated with a number of accumulated turns of a magnetic field. The multiturn counter includes a plurality of magnetoresistive elements electrically coupled in series with each other and a reference element. The plurality of magnetoresistive elements are formed in a magnetic strip. The reference element is separate from the magnetic strip. A strip width of the magnetic strip and a strip width of the reference element are similar. The plurality of magnetoresistive elements and the reference element can be coupled to a matrix of electrical connections.

Multiturn sensor arrangement

Aspects of this disclosure relate to controlling one or more vehicle systems based on a determined weather condition. In some embodiments, a radar system can be mounted on a vehicle and can collect weather data by receiving electromagnetic signals. A weather condition can be determined based on the collected weather data, and a vehicle system can be controlled based on the determined weather condition, such as vehicle lighting, windscreen wipers, or cruise control. In some embodiments, weather conditions can include fog, sleet, or smog. The weather condition can be determined by analyzing scattered reflections from incident microwaves and/or radio waves to determine a level of attenuation of the scattered electromagnetic energy indicative of a presence or absence of particles. A map can be displayed displaying the weather condition and controlling vehicle navigation systems. The collected weather data can be compared with data from a LiDAR or camera system for reliability.
