Abstract: A sensing device exhibits a tunneling magneto-resistive (TMR) effect, and changes electrical resistance in response to a magnetic field. A first current carrying conductor is positioned in proximity to the TMR sensing device, such that upon an application of a sufficient current, a magnetic field is generated. The magnetic field is sufficiently strong and properly oriented so as to cause a magnetization of a soft magnetic layer of the TMR sensing device, thereby causing a change of the TMR sensing device from one bi-stable state to another bi-stable state.

Abstract: A method and apparatus for enabling chemical identification of individual particles, cells of molecules by obtaining a Raman spectrum of a particle, cell or molecule as it flows past a sensing point in a flow cytometer. The particles, which may be cells or molecules, are associated with a suitable noble metal colloid or colloidal aggregate. Cellular particles may be associated with gold or silver colloidal particles by ultra-sonic sonification while in a sample preparation reservoir containing the gold or silver colloidal suspension. The colloid associated particles are then hydrodynamically focused into a single file by a fluid control module. The surface-enhance Raman Spectrum of individual particles are obtained by illuminating the particle with a laser as the particle flows past a sensing point and gathering the light that is non-elastically scattered (Raman scattered) by the particle. The surface-enhanced Raman spectrum is then analyzed to identify the particle.

Abstract: A thermal fluid flow sensor and method of forming same. The flow sensor has an integrated circuit substrate, such as a silicon substrate, and a region of low thermal conductivity material carried on the top surface of the integrated circuit substrate. One or more pairs of temperature sensing elements are disposed on the low thermal conductivity region together with a heating element so that a robust flow sensor can be provided at low cost. Signal conditioning circuitry is disposed on the same surface as the temperature sensing elements and connected to the sensing elements thereby further reducing costs and improving the flow sensor sensitivity.
