摘要： Systems and/or techniques associated with active control of electronic package warpage are provided. In one example, a system includes an electronic package and an integrated circuit. The electronic package includes a patterned structural material associated with a mechanical characteristic that changes in response to an applied condition. The integrated circuit controls the applied condition associated with the patterned structural material based on sensor data associated with a status of the electronic package.

摘要： A system that integrates camera images and quantity sensors to determine items taken from, placed on, or moved on a shelf or other area in an autonomous store. The items and actions performed may then be attributed to a shopper near the area. Shelves may be divided into storage zones, such as bins or lanes, and a quantity sensor may measure the item quantity in each zone. Quantity changes indicate that a shopper has taken or placed items in the zone. Distance sensors, such as LIDAR, may be used for shelves that push items towards the front. Strain gauges may be used for bins or hanging rods. Quantity changes may trigger analysis of camera images of the shelf to identify the items taken or replaced. Images from multiple cameras that view a shelf may be projected to a vertical plane at the front of the shelf to simplify analysis.

摘要： A method for detecting radial deformation in a winding of a transformer may include synthetic aperture radar (SAR) imaging of the winding using ultra high frequency (UHF) electromagnetic signals in a first instance of the winding to obtain a first image of the winding; SAR imaging of the winding using UHF electromagnetic signals in a second instance of the winding to obtain a second image of the winding; and comparing the first image of the winding and the second image of the winding to detect a radial deformation in the winding. The UHF electromagnetic signals may be transmitted as a plurality of successive sinusoidal signals, where frequencies of the successive sinusoidal signals gradually change from a first frequency to a second frequency.

摘要： The present invention relates to a force measurement device that includes mechanical amplification of linear elastic deformation along the axis of loading by estimating the quasi-linear incremental displacement between two points on arcs inscribed due to angular movements of a pair of cantilever arms located on opposite quadrants on a closed contour load sensing element to improve the sensitivity, and hence the resolution, of the force measurement device.

摘要： A microelectronic chip device includes a semiconductor substrate and multiple on-chip strain sensors (OCSS s) constructed on the substrate at various locations of the substrate. The OCSSs may each include multiple piezoresistive devices configured to sense a strain at a location of the various locations and produce a strain signal representing the strain at that location. A strain measurement circuit may also be constructed on the semiconductor substrate and configured to measure strain parameters from the strain signals produced by the OCSSs. The strain parameters represent the strains at the various location. Values of the strain parameters can be used for analysis of mechanical stress on the chip device.

摘要： Methods and systems suitable for fabricating multi-layer elastic electronic devices, and elastic electronic devices formed thereby. A method of fabricating an elastomer-based electronic device includes printing a first liquid material and then a second liquid material on a fabric substrate that comprises fibers. The first and second liquid materials are sequentially printed with a three-dimensional printer that directly prints the first liquid material onto the fabric substrate so that the first liquid material wicks through some of the fibers of the fabric substrate and forms a solid matrix of an elastomer-based composite that comprises the matrix and the fabric substrate, after which the three-dimensional printer directly prints the second liquid material on the elastomer-based composite to form a film thereon. The elastomer-based composite and film are electrical components of the elastomer-based electronic device.

摘要： A sensor for measuring movement of an object relative to a fluid has a housing fixed to a surface of the object and a spring on the housing formed by a plurality of blades each having an outer end fixed to the housing and an inner end connecting to a hub, with the plurality of blades defining a plane. Respective strain gauges are carried on the blades. A rigid pin is mounted on the hub of the spring, extends in a direction generally perpendicular to the plane, and projects from the surface of the object and into the fluid.
