    摘要: A strain gauge sensor system and method for measuring the strain in a member, such as a fiber rope, has a sensor target assembly having a plurality of magnets carried spaced apart by individual gauge lengths along the member. Position and trigger sensor devices are configured spaced apart along side a desired path of travel of the member. When the member is fed along the desired path of travel, the trigger sensor device, in response to magnetically sensing a passing magnet, triggers the position sensor device to read the position of an adjacent passing magnet. The strain in the gauge length is determined from the read position. RFID tags placed on the member between the magnets can be identified by an RF reader to identify a particular gauge length being measured. The system can include a deployment device for feeding the member along the desired path.

    摘要: A displacement sensor for providing an indication of the position of a first body relative to a second body, the first body being displaceable relative to the second body in a displacement direction. The sensor is composed of: two magnets that are spaced from one another in the displacement direction to define therebetween a region containing a magnetic field; a magnetic field sensing element mounted in the region; and components for coupling at least one of the magnets to one of the bodies and the magnetic field sensing element to the other of the bodies to produce a relative displacement between the at least one magnet and the magnetic field sensing element in the displacement direction in response to displacement of the first body relative to the second body.

    摘要: Described herein are magnetic sensors (e.g., force sensors) as well as methods of making and using thereof The magnetic sensors can employ a soft magnetic composite (e.g a composite comprising a population of magnetic particles dispersed within an elastomeric resin) paired with a magnetometer. These sensors can overcome many of the traditional shortcomings that have hampered the effectiveness of existing compression sensors in certain applications, including large size, a lack of 3-dimensional sensing capacity, need for sensors to incorporate rigid components, and/or signal quality issues associated with the orientation or deformation of soft composites under compression.

    摘要: A method of manufacture of a force sensor and a force sensor is provided. The force sensor can be used to measure contact forces. The force sensor includes a substrate with an electromagnetic sensing element for contactless sensing of a field formed by a target. The target is included in a flexible piece which receives the force, and can deform by it. The flexible piece is treated so that the force sensor is reliable and has long durability.

    摘要: 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.

    摘要: A magnetic load sensor is provided which is high in axial rigidity. The load sensor includes a pair of parallel plate coupled together by coupling pieces. The coupling pieces are inclined relative to the axial direction such that when an axial load is applied to the parallel plates, the parallel plates are displaced relative to each other in a direction perpendicular to the axial direction, due to deflection of the coupling pieces. A magnetic target is mounted to the parallel plate, and a magnetic sensor element is mounted to the parallel plate such that when the parallel plates are displaced relative to each other in the direction perpendicular to the axial direction, the magnetic target and the magnetic sensor element are displaced relative to each other in the direction perpendicular to the axial direction.
