摘要： The application describes devices, systems and methods related to an implantable device that is a stent or a heart valve. The implantable device includes a pressure sensor. The implantable device is for being introduced into a subject and for being wirelessly read out by an outside reading system. The pressure sensor comprises a casing with a diffusion blocking layer for maintaining a predetermined pressure within the casing and a magneto-mechanical oscillator with a magnetic object providing a permanent magnetic moment. The magneto-mechanical oscillator transduces an external magnetic or electromagnetic excitation field into a mechanical oscillation of the magnetic object, wherein at least a part of the casing is flexible for allowing to transduce external pressure changes into changes of the mechanical oscillation of the magnetic object.

摘要： A strain compensated temperature sensor includes a first, temperature dependent resistor, and a second, substantially temperature independent resistor connected in series with the temperature dependent resistor. At least one electrical contact allows an electrical potential difference to be applied across both resistors simultaneously. Both the temperature dependent resistor and the substantially temperature independent resistor are sensitive to mechanical strain. This permits temperature readings from the sensor to be corrected automatically for mechanical distortion of the sensor. The temperature dependent resistor and the substantially temperature independent resistor are of substantially similar construction, preferably being located adjacent one another in or on a common substrate, and hence have a similar response to a mechanical force applied to them.

摘要： The invention relates to a method of temperature determination independent of pressure by means of a metal membrane (1). A bridge circuit (5) with several resistances is (6, 7, 8, 9) mounted thereon. A resistance pair (10) of the resistances (6, 7, 8, 9) is located close to the centre, another resistance pair (11) of the resistances (6, 7, 8, 9) is located remote from the centre. The resistances (6, 7, 8, 9) are arranged on the metal membrane such that the tensile elongation (Δ1) of the resistance pair (10) of the resistances (6, 7, 8, 9) near the centre is of the order of the compression (-Δ1) of the resistance pair (11) of the resistances (6, 7, 8, 9) remote from the centre.

摘要： An analog sensor with digital compensation function includes a deformation part generating a deformation relating to a pressure sensed by the analog sensor; a strain gauge connected to the deformation part and generating a change in resistance relating to the deformation; a strain gauge bridge connected to the strain gauge and transferring the change in the resistance of the at least one strain gauge to output a first analog signal; and an analog-to-digital conversion module converting the first analog signal to a first digital signal, representative of weight. A signal processing and output circuit compensates the first digital signal and converts it into a second analog signal.

摘要： The invention relates to a device for determining the pressure and temperature in the suction pipe of an internal combustion engine with a temperature sensor (50) and pressure sensor (30) positioned in a common housing (10), said pressure sensor being fixed on a support (20), together with an evaluating circuit, with as few distortions possible. The aim of the invention is to improve the device in such a way that it is easy to produce and enables temperature to be measured precisely and especially pressure to be measured very precisely. To this end, it is suggested that a connection piece (40) attached to the housing (10) is provided for delivering a medium under pressure, as well as an intermediary piece (60) which is connected to both the support (20) and said connection piece (40) via seal bonds (61), said seal bonds neutralising mechanical distortions.

摘要： 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.

摘要： 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.
