Abstract: A capacitive sensor device includes first and second sensor capacitors coupled in series, a clock signal generating part, an operational amplifier, a feedback capacitor, a compensating capacitor, and a compensating signal generating part. The clock signal generating part generates a first clock signal and the second clock signal applied to the first and second sensor capacitors, respectively. The compensating signal generating part generates a compensating signal applied to the compensating capacitor. The first clock signal and the second clock signal have the same frequency and the same amplitude and have phases being opposite each other. The compensating signal has a frequency same as the first clock signal and the second clock signal, has a phase same as one of the first clock signal and the second clock signal, and has an amplitude that is adjustable.

Abstract: The application describes methods and apparatus for distributed fibre sensing, especially distributed acoustic/strain sensing. The method involves launching interrogating radiation in to an optical fibre and sampling radiation backscattered from within said fibre at a rate so as to acquire a plurality of samples corresponding to each sensing portion of interest. The plurality of samples are divided into separate processing channels and processed to determine a phase value for that channel. A quality metric is then applied to the processed phase data and the data combined to provide an overall phase value for the sensing portion based on the quality metric. The quality metric may be a measure of the degree of similarity of the processed data from the channels. The interrogating radiation may comprise two relatively narrow pulses separated by a relatively wide gap and the sampling rate may be set such that a plurality of substantially independent diversity samples are acquired.

Abstract: A method and a device are for an automated comparison of at least two sets of measuring values. The measuring values of the two sets are assigned respectively to one class from a finite number of classes defined by indices so that a frequency distribution is defined respectively for each of the two sets, which frequency distribution indicates for each class a frequency of the measuring values assigned to this class. A distance measure reflecting a similarity or dissimilarity between the two sets of measuring values between these frequency distributions is calculated as a function of a final value of a first auxiliary value termed here match by way of example. The first auxiliary value match is calculated by an algorithm using two sets of variables in that, with a given maximum distance dmax≧1 for all integral distances d with 0≦d≦dmax, beginning with d=0 and continuing to larger distances d, respectively for all indices i and j at a distance from each other by the distance d. A current value of a further auxiliary value is defined as m=min (qi′, vj′), m stands for the further auxiliary value, qi′ for the variables of a first of the two sets of variables and vj′ for the variables of the second set of variables, the variables of the two sets of variables being defined at the beginning of the algorithm as qi′=qi, vj′=vj, wherein qi stands for the frequencies from a first of the two frequency distributions and vj for the frequencies of the second frequency distribution. Respectively the variables qi′ and vj′ are defined again by subtracting the current value of the further auxiliary value m and the current value of the further auxiliary value m, multiplied by a matrix element ai, j, is added to a current value of the first auxiliary value match defined originally as match=0, the matrix elements ai, j forming a similarity matrix with ai, i=1 for all indices i and 0≦ai, j≦1 for all indices i and j at a distance of at most dmax with i≠j.

Abstract: Embodiments of the present disclosure are directed to MEMS-based medical devices including a flexible housing that forms a chamber for encapsulating a fluid or liquid. The devices also include encapsulated electrodes, portions of which are exposed to the fluid or liquid within the chamber for sensing and/or physical actuation (controlled movement). Such medical devices can function specifically as: contact force sensors; and/or out-of-plane actuators. Device function is enabled by the encapsulation of liquid within the microchamber. Depending on the kind of electrical input applied, the encapsulated electrodes can function as electrochemical sensing elements; and/or electrolytic generation electrodes. Devices according to the present disclosure can have a fluidic coupling to the external environment or can be isolated. Fluidic isolation from the surrounding environment can be accomplished by the inclusion of an annular-plate stiction valve within the device. Related methods of use and fabrication are also described.

Abstract: A system for measuring a capacitor (CSENj) precharges a CDAC (23) in a SAR converter (17) to a reference voltage (VAZ) and also precharges a first terminal (3-j) of the capacitor to another reference voltage (GND). During a measurement phase, the CDAC is coupled between an output and an input of an amplifier (31) and the capacitor also is coupled to the input of the amplifier, so as to redistribute charge between the capacitor and the CDAC. The amplifier generates an output voltage (VAMP) representing the capacitance being measured. The output voltage is stored in the CDAC. The SAR converter converts the output voltage to a digital value representing the capacitance being measured.
