Abstract: A sensor cluster is disclosed comprising a first plurality of side surfaces of a first N-hedron structure, and a second plurality of side surfaces of a second N-hedron structure. A first plurality of a first type of sensor are mounted on the first plurality of side surfaces, and a second plurality of a second type of sensor are mounted on the second plurality of side surfaces. N is greater than three and the first plurality of side surfaces are interleaved with the second plurality of side surfaces.

Abstract: A computer system comprising N real sensors for generating N real sensor signals, and a multiplexer for selecting M of the real sensor signals from the N of real sensor signals, where M is less than N. The computer system further comprises a combiner for combining the M real sensor signals to generate a virtual sensor signal representing an output of one of the unselected N real sensors.

Abstract: A vehicle, and a balancing device and method of controlling a state of charge of a reference electrode in a battery. The balancing device includes a measurement circuit and a charging circuit. The measurement circuit is configured to obtain a measurement of a reference voltage of the reference electrode. The charging circuit is configured to adjust the reference voltage based on the measurement. The state of charge of the reference electrode is controlled based on the reference voltage.

Abstract: Dimensions of a disk resonator gyroscope along the radial line of a resonator can be varied to engineer radial stiffness. An apparatus may comprise: a resonator comprising a plurality of concentric circumferential segments and a plurality of slots formed between the concentric circumferential segments; and at least one support supporting the resonator, wherein a width, in a radial direction, of each of the concentric circumferential segments is varied depending on a distance from the at least one support to the each of the concentric circumferential segments. The apparatus may further comprise radial segments connecting between the concentric circumferential segments. The concentric circumferential segments may have a ring shape.
