Title: Magnetoresistive sensor based on the spin valve effect
Inventor: DIENY BERNARD
IPC: G11B5/00
Filed: 1991-10-31
Granted: 1994-05-03
Abstract: MAGNETORESISTIVE SENSOR BASED ON THE SPIN VALVE EFFECT          ABSTRACT OF THE DISCLOSURE      A magnetoresistive (MR) sensor comprising a first and a second thin film layer of a magnetic material separated by a thin film layer of a non-magnetic metallic material.  The first  ferromagnetic  layer  is  magnetically  soft.   The magnetization  direction  of  the  first  layer  of  magnetic material   is   set   substantially  perpendicular  to  the magnetization of the second layer of magnetic material at zero applied field, and the magnetization direction of the second layer of magnetic material is fixed.  A current flow is produced through the MR sensor,  and the variations in voltage across the MR sensor are sensed due to changes in resistance of the MR sensor produced by rotation of the magnetization in the first layer of magnetic material as a function of the magnetic field being sensed.  The variation of the resistance with the angle between the magnetizations of the first and second layers of magnetic material has been defined as the spin valve (SV) effect.   It is also shown that, by a suitable direction of the current with respect to the fixed magnetization, the (SV) magnetoresistance can be added    constructively    to    the  usual    anisotropic magnetoresistance.

Filed: 1993-08-09
Granted: 1999-03-30
Abstract: A vehicular collision avoidance radar system using digital signal processing technique including a transmit section (202) that generates a two channel transmit frequency. An antenna (210) both transmits the transmit signal and receives a reflected receive signal. A Schottky diode mixer (208) generates a difference signal having a frequency equal to the transmit frequency minus the receive frequency. A signal switch (304) in a front end electronics section (300) time demultiplexes and samples the channel 1 and channel 2 signals. The samples are coupled to a two-channel analog to digital (A/D) converter (310). A digital electronics section (500) receives the digital information and performs a Fast Fourier Transform (FFT) on each channel of digital data to determine relative speed and range of a target based upon the frequency and the difference in phase of the two channels. The digital electronics section also receives information regarding the status of vehicle operation and/or controls to determine the degree of danger presented by an identified target.
