Abstract: An electric toothbrush (10) and method of operating an electric toothbrush. The electric toothbrush includes a handle portion (14) having a shaft (38) configured to receive a brushing load from a bristled end (18) of a brush head (12). A sensor assembly (30) is configured to determine a deflection proportional to the brushing load with respect to a first direction (24) associated with the brushing load. The sensor assembly includes an air gap (32) and is configured to determine the deflection based on changes in the air gap. A mounting bracket (50) is connected between opposite sides of the air gap, the mounting bracket having a first bending stiffness with respect to the first direction, and a second bending stiffness with respect to a second direction (28) generally opposite to the first direction. The first bending stiffness is greater than the second bending stiffness.

Abstract: This invention concerns devices, systems, and methods to induce motion in cantilevers for actuation and sensing applications. Motion is induced by applying current to a ferromagnetic, magnetostrictive cantilever subject to bending stress, and hence strain (deflection), having both elastic and magnetoelastic components. The applied current creates a magnetic field that reorients the magnetoelastic strain component, changing the total strain and thus the total deflection. Changing deflection can be harnessed for actuation or work. Moreover, considering both static and dynamic deflection, measureable parameters that are associated with beam deflection, vibration frequency, and/or amplitude can be measured.

Abstract: The present invention relates to an arrangement for measuring a force and/or a torque (Mt) on a machine element extending along an axis, using the inverse magnetostrictive effect. The machine element has at least two magnetization areas for magnetization purposes, extending circumferentially around the axis. In addition, there are magnetically neutral areas, each area being arranged axially between the magnetization areas and/or axially next to the magnetization areas. The arrangement further includes at least one first magnetic sensor, a second magnetic sensor and a third magnetic sensor, each of which is designed to individually measure a direction component of a magnetic field caused by the magnetization and also by the force and/or torque (Mt) and each of which lies in a different axial position. According to the invention, the third magnetic sensor lies in an axial position of one of the magnetically neutral areas.

Abstract: A device includes a first sensor and a second sensor. The first sensor is configured to generate a first signal corresponding to a detected first force. The second sensor is configured to generate a second signal corresponding to a detected second force. The first force and the second force has a substantially common direction. The device includes a processor configured to determine a measure of tension using the first signal and using the second signal. The measure of tension corresponds to displacement of an elongate member.

Abstract: A robotic sensing and touch apparatus detects gradual deformations in a resilient surface, in contrast to conventional rigid member displacement. Hall effect sensors coupled to rare-earth magnets in a deformable base allow sensing of surface curvature and compression against grasped objects. The deformable base, such as a silicone mold or other resilient encapsulation, fixes a magnetic source and an opposed Hall effect sensor. Calibration of a received magnetic field is defined by a sensor element voltage in an “at rest” (undeformed) state, and at successive degrees of deformation resulting from compression of the deformable base that draws the magnet in different orientations relative to the Hall effect sensor. An array of magnet and sensor element pairs allows relative sensing over an area for detecting curvature of a translated or articulated member, or engagement with a curved surface.
