Abstract: In one general aspect, a composite foam comprises a non-layered mixture of a polymeric foam with a plurality of voids; and a plurality of conductive fillers disposed in the polymeric foam. The conductive fillers are disposed in an even manner from outer surface to outer surface. In some implementations, the conductive fillers are up to 25% by weight of the composite foam. In some implementations, the composite foam may be used as padding. In some implementations, the composite foam may be used as a strain gauge. In some implementations, the foam may be in contact with a voltage detector.

Abstract: A weight sensor comprises a sensing system including a target piece and a sensing element, configured to provide changes of a magnetic field, being generated by motion of the target piece. The sensing element senses these changes and provides a signal representative of the position of the target piece. An integrated circuit with processing means can process signals from the sensing element. The flexible piece receives a force stimulus, so that upon exerting a force on the flexible piece by a product due to the weight of said product, the displacement of the target piece with respect to sensing elements can be sensed.

Abstract: Disclosed are devices and systems designed to assist an examiner in assessing the level of pain sensitivity in a patient, along with methods of using of the devices and/or systems. The device contains a tip for applying pressure to a point of the patient's body; a pressure sensor used to measure the pressure; a displacement sensor used to measure the depth of probing; and an optional third sensor used to measure temperature. The device can therefore simultaneously measure the pressure applied by the probe and the distance travelled by the tip of said probe (i.e. the displacement achieved). The device can be included in a system, which receives the data from the aforementioned sensors, and the patient's perceived pain value on a scale of 1-10. These values can be analyzed over time (i.e. over multiple applications of the device) to permit the examiner to use the data obtained to assess potential changes in the level of pain or discomfort and/or amount of healing of the patient.

Abstract: A measuring element for registering forces includes a first measuring arm extending in a longitudinal direction of the measuring element, a second measuring arm extending in the longitudinal direction, a deformation section connecting the first measuring arm and the second measuring arm to one another in an elastically deformable manner, and a transformer unit arranged on a first side or a second side of the deformation section. The first measuring arm and the second measuring arm can be deflected relative to one another in a direction perpendicular to the longitudinal direction. The transformer unit responds to deformation and is situated fully within the deformation section.

Abstract: Methods of measuring a force using a tracking system are disclosed. A first vector is determined between a first tracking array and a second tracking array on a tool. The tool has a flexible portion that has a known modulus of elasticity and moment of inertia. A force is applied to the tool, and a second vector is determined between the first tracking array and the second tracking array. An amount of deflection is determined for the tool, and the magnitude and direction of the applied force are determined based on at least the amount of deflection, the modulus of elasticity and the moment of inertia. Information pertaining to the magnitude and direction of the applied force is provided to a user.
