The present disclosure provides an electromechanical actuator comprising an actuator drive unit housing, a relief formed in the actuator drive unit housing, a column defined by the relief positioned adjacent to a second relief, and a load cell comprising the column and a strain gauge coupled to the column.

A method of reading and quantifying pressure points or bumps or a product outline to extract a pattern that, when decoded, uniquely defines a product or class of products by defining the theoretical centers of applied pressure, determining the spatial relationship between more than one center or a product outline to define which pattern belongs to which product, and correlating each pattern with templates of stored patterns to determine what product is represented by each respective pattern.

A load cell to measure displacements transferred by a fifth wheel to the load cell includes an elongated mounting base portion configured to attach to a support structure of a tractor, a coupling portion configured to pivotally support a fifth wheel, a middle portion disposed above the elongated mounting base portion and below the coupling portion, the middle portion including a hollow interior section with an opening into the hollow interior section, and a post extending from the elongated mounting base portion and protruding into the hollow interior section of the middle portion.

An information output device that can output the position of a load applied to the pedal is provided. A strain gauge is provided on the inner face of a crank of a bicycle and detects strain occurring in the crank. A cycle computer display unit displays an image showing the center position of the load applied to the pedal connected to the crank based on the tangential force and the torsional torque calculated based on the output values of the first strain gauge to the sixth strain gauge.

An electronic measurement unit for a polymorphous device, comprising a number of lateral structures, each lateral structure including: a support structure; at least one sensor constrained to the support structure and generating an electrical signal indicative of a deformation of the support structure; and a coupling structure that constrains a corresponding external covering element to the support structure in a releasable manner, so that when the external covering element is constrained to the support structure and an external force acts on the external covering element, the electrical signal is indicative of the external force.

A load can be applied to a beam and a property of the load can be calculated. In one example, a first shear gauge can be configured for positioning on a neutral axis of a beam on one side of a force that the beam is subjected to. Similarly, a second shear gauge can be configured for positioning on the neutral axis of the beam on an opposite side of the force to the first shear gauge. A calculator can be configured to identify a characteristic of the force through use of an output of the first shear gauge and through use of an output of the second shear gauge.

For measuring tensile and/or compressive loads force measuring systems are provided for measuring a tensile and/or compressive load of a structure have a first force measuring sensor assigned to the structure, and a second force measuring sensor assigned to the structure. To provide a force measuring system that enables high measuring accuracy, the first and the second force measuring sensor differ in such a way, that the first force measuring sensor is designed to measure a nominal load range, and the second force measuring sensor is designed to measure a sub-range of the nominal load range.

Various sensor systems are described herein, including inserts having sensors thereon, which are configured to be received in an article of footwear. The inserts may be connected to a sole member of the footwear, or may function as a sole member. The sensors may be piezoelectric sensors in some configurations. The system may also include an electronic module that is overmolded into the sole structure and includes a connector for external access.

A robotic vehicle may include control circuitry configured to execute stored instructions to direct operation of the robotic vehicle on a defined area, and an electrical resistance sensor in communication with the control circuitry. The electrical resistance sensor may be configured to detect motion indicative of a lift event and a collision event using a single sensor.

A pressure reading assembly including a housing defining a conduit configured to transmit bodily fluid therethrough and a receiving tube having a first opening and an inner cylindrical surface. The pressure reading assembly further includes a sensing apparatus which includes a sensor disposed on a substrate and an engagement member including a generally columnar sealing member configured to engage an inner cylindrical surface of a receiving tube within the housing connected to the substrate about the sensor. The sealing member defines an axial bore extending from a proximal end to a distal end and includes an outer sealing surface defining one or more engaging elements configured to non-adhesively engage the inner cylindrical surface of the receiving tube to resist removal of the sensor assembly so that a pre-sterilized sensor assembly can be removed from a clean sealed packaging and joined directly with the housing.
