Chips that include one or more particle manipulation mechanisms, or force transduction elements, provided at specific locations to manipulate and localize particles proximal the substrate surface. In one embodiment, individually addressable magnetic control mechanisms such as electric coils are provided at specific locations to create a magnetic field to attract magnetic particles, such a magnetic or magnetizable beads, to those specific locations. In another embodiment, electrostatic control mechanisms such as electrodes are provided to attract and manipulate electrically charged micro-particles. A location may include a crater or well formed in the substrate, or it may include an element on the surface of the substrate. In some embodiments, one or more sensors are located proximal specific locations, e.g., specific craters, so as to analyze specific conditions at each location. In other embodiments, multiple locations share one or more sensors.

A device and method for indicating if a fastening element upon fastening to a piece has reached a tensile yield limit load. The fastening element includes a threaded shaft having a magnetostrictive material. The device includes a mechanism for generating an alternating magnetic field that penetrates the shaft, a mechanism for measuring a physical quantity that depends on the momentary magnetic susceptibility of the shaft and a control unit adapted to detect a significant change of the physical quantity and determine and indicate if the shaft of the fastening element has reached the tensile yield limit load.

The invention concerns a system for measuring the alignment error of two axles provided with a first and a second coupling part by means of a biaxial orthogonal magnetic sensor system comprising a sensor and a magnet, wherein said sensor is designed to be placed on the first coupling part with its one direction of sensing oriented in one direction of magnetization of said magnet, which magnet is designed to be placed on the other coupling part and means for reading off an angle error and offset error independently of each other during the rotation of the axles on-line. The system moreover includes a reference sensor for determining said angle error and offset error orientation relative to a known direction.

A device for detecting a magnetic field response or changes in a magnetic response of at least one magnetic particle in a carrier fluid, the detection comprising measuring the magnetic particles characteristic rotation period, and the measurement involving measurement of a Brownian relaxation in the carrier fluid under influence of an external pulsed magnetic field. The device includes means for generating the pulsed magnetic field, at least two substantially identical detection coils connected in gradiometer coupling to detection electronics for measuring the differential induced voltage which is dependent on the frequency dependent susceptibility or the magnetization change.

A magnetic separator unit for the selective separation of at least one component from a fluid mixture is described. The unit can include at least one mandrel-shaped magnet unit and tubing wrapped around it. Fluid containing magnetisable particles can be passed through the tubing to allow attraction of the particles to the magnet unit.

Magnetic separator

A method for detecting changes of magnetic response of at least one magnetic particle provided with a external layer in a carrier fluid, comprising measuring the characteristic rotation time of the magnetic particle with respect to the external layer, and measuring Brownian relaxation in the carrier fluid under the influence of an external alternating magnetic field. The method implies that upon modification of the effective volume of the particle or its interaction with the carrier fluid, a hydrodynamic volume of the particle changes, which implies a change of the frequency (&fnof; ) at which an out of phase component of the magnetic susceptibility has its maximum.
