20100085040APPARATUS AND METHOD FOR DETERMINING SPEED AND DIRECTION OF SLOTTED TARGETS UTILIZING DUAL MAGNETIC SENSOR PACKAGING - A magnetic sensing apparatus and method that determines the speed and direction of gears or slotted targets. A magnet can be placed proximate to the slotted target to create a magnetic field. An integrated circuit is formed on a substrate containing two or more magnetoresistive sensors occupying the same area. This integrated circuit is biased from the magnet which is placed in close proximity. The magnetoresistive sensors are intertwined with the first magnetoresistive sensor, offset from the second magnetoresistive sensor. The magnetoresistive sensors produce phase shifted output signals representing magnetic flux flowing through the magnetoresistive sensors such that the magnetoresistive sensors are reactive to gap and angular changes in the circular track of the ferrous target. The phase shift of the signals needed to determine direction is sufficiently maintained for a variety of target feature sizes and spacing.04-08-2010
20100097051INCREMENTAL POSITION, SPEED AND DIRECTION DETECTION APPARATUS AND METHOD FOR ROTATING TARGETS UTILIZING MAGNETORESISTIVE SENSOR - An apparatus and method that determines the incremental speed, position and direction of rotating targets using magnetoresistive sensors. A magnet is mounted on a rotating target on the same axis of rotation such that the magnet spins with the target. A magnetoresistive sensor is positioned proximate to the magnet such that the changes in magnetic field are detected by the sensors. An interpolating integrated circuit divides signals into small angular increments and converts data to digital form. These signals can be used to determine the angular speed, position, and direction of the rotating target. This results in a much more accurate determination of angular speed, position and direction of a rotating target regardless of the composition of the target or the environment in which it operates.04-22-2010
