The invention relates to a nuclear magnetic resonance imaging radio frequency-receiver (), the receiver () being adapted to receive analog signals from at least one radio frequency receiver coil unit (), the radio frequency receiver () comprising: an analog-digital converter () to convert the analog pre-amplified magnetic resonance signal into a digital signal, means () for digital down converting the digital signal and a first communication interface () adapted for transmitting the down converted digital signal via a communication link (e.g. wireless, optical or wire-bound).

The present invention provides a magnetic biosensor device comprising a sensor cartridge for receiving an assay to be tested, an electromagnetic unit for producing a magnetic field at a sensor surface of the sensor cartridge, and detection means for detecting the presence of magnetic particles close to the sensor surface. The electromagnetic unit is adapted to periodically produce a magnetic field having at least a first and a second magnetic field strength, the ratio of the amount of time of applying the first magnetic field strength to the amount of time of the period of applying the first and the second field strength being varied during the measurement. The invention further provides a method for applying a magnetic field to a sensor surface of a magnetic bio sensor device.

Mixed actuation protocol for a magnetic biosensor device

In an example embodiment, a magnetic sensor has a magnet and a magneto-resistive, arranged on a substrate such that magnetic field lines through the magneto-resistive element are substantially parallel to a plane of the substrate. Movement of a movable magnetically permeable element MMPE near the substrate is detected as it alters the number of field lines through the element. The MMPE can be more sensitive than devices arranged with perpendicular field lines, and can be easier to manufacture and integrate. Applications include analog pointers, pressure sensors and microphones. The MMPE can use magnets placed either side of the element to detect changes in size of a gap above the element. As the gap closes, less of the parallel oriented field passes through the magneto resistive element.
