  • Patent number: 10060943
    Abstract: Apparatus and associated methods relate to maximizing a signal to noise ratio of an accelerometer by inhibiting signals arising from movements of a proofmass in directions perpendicular to a direction of intended sensitivity. The direction of intended sensitivity of the accelerometer is along an axis of the proofmass. The accelerometer is rendered substantially insensitive to lateral accelerations of the proofmass by making the accelerometer axially symmetric. Two axially-asymmetric acceleration sensing devices are axially engaged in such a manner as to render the coupled sensing devices substantially axially-symmetric. In some embodiments, each acceleration sensor has an axially-thin membrane portion extending from a proofmass portion. The two acceleration sensors can be engaged in an antiparallel fashion at projecting ends of the proofmass portions.

  • Patent number: 10054504
    Abstract: A load change detection apparatus is provided with a base member, an elastic member, a first plate, a fixing member and heat flow sensors. The elastic member deforms according to a changed load applied to the elastic member, received by the receiving member. The first plate supports a surface of the elastic member on a side of the base member. The fixing member fixes the lower plate and the elastic member to the base member. The heat flow sensors, provided between the base member and the lower plate, output signals according to heat flowing between the lower plate and the base member. The heat flows due to heat generated or heat absorbed when the elastic member changes the elasticity shape thereof. Stress occurring when the elastic member deforms, is shut off by the first plate, thus direct transmission of the stress to the heat flow sensors is avoided.
