Abstract: In one implementation, a footfall detection assembly comprising a sensor underlayment unit and a data analysis device is provided. The sensor underlayment unit comprises a sensor having a unique sensor identifier and a plurality of zones, wherein the sensor is configured to measure zone capacitance in of the plurality of zones, and a processing unit operably connected to the sensor. The processing unit is configured to receive the measured zone capacitance values from the sensor upon the occurrence of a change in measured zone capacitance of the sensor and generate and transmit a data packet comprising at least the unique sensor identifier and measured zone capacitance values upon occurrence of a change in capacitance of at least one of the plurality of zones of the sensor. The data analysis device is configured to receive the data packet, compare the measured zone capacitance values of the data packet to previously-measured zone capacitance values associated with the sensor underlayment into and generate a result therefrom.

Abstract: Device with isotropic planar compliance comprising a floating body (2) positioned between a first (3) and second frame (4), said floating body having an extended portion (21) protruding through the first frame, at least a row of caged balls (5) supporting the floating body, at least one elastic element (6) positioned over the extended portion of the floating body, compressed between and connecting the floating body and the first frame. Said caged balls allow the at least one elastic element to laterally deform, so that their axis bends, while the ends of said at least one elastic element lay on two parallel planes, which remain at constant distance while sliding one with respect to the other. The device comprises also at least one displacement sensor (10), for measuring the displacement of the floating body with respect to the first or second frame.

Abstract: An on-chip strain measurement device that uses precision frequency measurements to precisely extract sub-nm displacements, allowing residual strain measurements in a given structural film. Strain-induced gap changes to resonance frequencies use differential strategies to remove bias uncertainty, allowing measurement of sub-nm displacements. Gap-dependent electrical stiffness is used to shift resonance frequencies as structural elements stretch or shrink to relieve strain. An output based on differential frequencies between two proximal structures with unequal stress arm lengths removes uncertainty on the initial gap spacing. The ability to precisely measure the frequency of the high-Q structures allows lifetime stress correction of micromechanical circuits, such as oscillators and filters.

Abstract: An electrode structure is an electrode structure that is wound around a rim of a steering wheel and includes: a base material including a first region disposed on a front surface side of the rim and a second region disposed on a back surface side of the rim; a first sensor electrode disposed in the first region; and a second sensor electrode disposed in the second region. When the steering wheel is in a neutral position, in a lower-limb facing portion of the rim that faces a lower limb of a driver, neither the first sensor electrode nor the second sensor electrode is disposed, or only one of the first sensor electrode or the second sensor electrode is disposed.

Abstract: In a sensor assembly (30), a sensor electrode (34) and a sensor electrode (36) are stacked on one another, and the sensor electrode (36) is disposed inward of the sensor electrode (34) in a radial direction of a rim portion (16). Further, an outer side, in a radial direction of a steering wheel (14), of the sensor electrode (36) is covered by the sensor electrode (34), and projecting margin portions (40) that are exposed from the sensor electrode (34) on the radially inner side of the steering wheel (14) are formed in the sensor electrode (36). As a result, in the sensor assembly (30), a structure for a palm to come into contact with the sensor electrode (34) and for a finger of a driver to come into contact with the projecting margin portions (40) of the sensor electrode (36) when the driver grips the steering wheel (14) is simplified.
