Abstract: A dual integrator system (200) comprises two integrators (220A-B), an output stage (270), and a switching network (240 A-D). The first and second integrators receive a differential Hall sensor signal (205, 210) and a reference voltage (210). The first integrator outputs a first integrator signal (225A) based on the differential Hall sensor and the reference voltage. The second integrator outputs a second integrator signal (225B) based on the differential Hall sensor signal and the reference voltage. The first integrator comprises a first offset cancellation feedback loop (235 A), and the second integrator comprises a second offset cancellation feedback loop (235B). The switching network is coupled to the first and second integrators and to the output stage, and alternates which of the first and second integrators is coupled to the output stage. In some embodiments, the first and second integrators each perform a reset operation, a sampling operation, an integration operation, a differential to single-ended conversion operation, and a holding operation.

Abstract: A metrology device (1) for determining metrological characteristics of a sample (S) is provided that comprises a probe (20), a scanning mechanism (30), a radiation source (40), an optical sensor (50) and a signal processor (60). In operation the scanning mechanism (30) displaces the probe relative to the sample, along a surface of the sample. The probe (20) has a diamond tip (21) with one or more nitrogen-vacancy (NV) centers and is irradiated by the radiation source (40) with photon radiation to therewith excite the tip to emit fluorescent light. The optical sensor (50) provides a sense signal indicative of an intensity of the emitted fluorescent light and the signal processor (60) processes the sense signal to compute at least one characteristic of a feature present in the sample.

Abstract: A soft magnetic sensor comprising a soft material containing randomly distributed magnetic microparticles and a magnetometer that can estimate force and localize contact over a continuous area. A reference magnetometer can be used to filter motion and ambient noise. Methods for locating contact and determining force comprise data analysis of the magnetometer output. In some embodiments, the sensor can localize an object prior to contact.
