Abstract: A pressure sensing unit comprises a membrane and two permanent magnets inside the cavity. One magnet is coupled to the membrane, and at least one magnet is free to oscillate with a rotational movement. At least one magnet is free to oscillate with a rotational movement. The oscillation takes place at a resonance frequency, which is a function of the sensed pressure, which pressure influences the spacing between the two permanent magnets. This oscillation frequency can be sensed remotely by measuring a magnetic field altered by the oscillation. The pressure sensing unit may be provided on a catheter or guidewire.

Abstract: A method of detecting temperature of an electrical terminal. The method includes: applying a material patch to a surface of the electrical terminal, the material patch containing a polymer matrix with a polymeric positive temperature coefficient material which contains a mixture of electrically conductive magnetic particles, whereby the material patch does not appreciably increase the electrical resistance or thermal capacitance of the electrical terminal; and remotely sensing a change in the material patch with an electrically isolated circuit which is external to the electrical terminal to determine if the electrical terminal is operating at a safe temperature to optimize current flow across the electrical terminal.

Abstract: The invention relates to a marker device and a tracking system for tracking the marker device, wherein the marker device comprises a rotationally oscillatable magnetic object and wherein the rotational oscillation is excitable by an external magnetic field, i.e. a magnetic field which is generated by a magnetic field providing unit 20, 31 that is located outside of the marker device. The rotational oscillation of the magnetic object induces a current in coils, wherein based on these induced currents the position and optionally also the orientation of the marker device is determined. This wireless kind of tracking can be carried out with relatively small marker devices, which can be placed, for instance, in a guidewire, the marker devices can be read out over a relatively large distance and it is possible to use a single marker device for six degrees of freedom localization.

Abstract: The application describes embodiments including, e.g., a measurement device comprising: a casing, a first magnet arranged within the casing such that it is rotatable out of an equilibrium orientation responsive to an external magnetic torque acting on the first magnet, a second magnet to provide a restoring torque to force the first magnet back into the equilibrium orientation responsive to an external magnetic torque rotating the first magnet out of the equilibrium orientation, allowing for a rotational oscillation of the first magnet, which is excited by the external magnetic torque, with a resonant frequency, and a temperature sensitive magnetic material to modify the resonant frequency.

Abstract: Devices and methods are provided for determining the temperature of an object. Such devices and methods incorporate first and second thermally conductive members, with a heating member associated with the first thermally conductive member. The second thermally conductive member is positionable adjacent to the object. The heating member is heated to a known temperature and a probe member is alternately brought into contact with the first and second thermally conductive members. When the probe member is in contact with one of the thermally conductive members, it will send an input to the controller. The controller compares the inputs to each other and, if they are not substantially equal, changes the temperature of the heating member, and the probe member is again alternately brought into contact with the thermally conductive members. When the inputs are substantially equal, the controller generates an output based on the temperature of the heating member.

Abstract: A thermomagnetic temperature sensor, a temperature measurement system and a method of measuring temperature employ a temperature-dependent resonant frequency of a thermomagnetic resonator to measure temperature. The thermomagnetic temperature sensor includes a thermomagnetic inductor and a capacitor connector to form the thermomagnetic resonator. The thermomagnetic inductor includes a ferromagnetic material having a temperature-dependent magnetic permeability to determine the temperature-dependent resonant frequency. A predetermined relationship between the temperature-dependent resonant frequency and temperature in a range between a maximum magnetic permeability value and a Curie temperature provides the measurement of temperature.
