  • Patent number: 10099878
    Abstract: Baseline values for metal detection readings associated with an item inserted into an infeed mouth of a depository are obtained before the item is pinched on a pathway of the depository. The baseline values are adjusted by additional readings obtained when the item is pinched on the pathway for transport. The adjusted baseline values are processed with calculated values from ongoing and fluctuating current readings to determine at least one final value. A determination is made as to whether the item includes at least some metal based on comparison of the at least one final value and a predefined value.

  • Patent number: 9914212
    Abstract: Disclosed is a tactile sensing and integrated vision system that surmounts problems of existing systems. The tactile sensing skin can be formed into any shape, size, or form factor, including large areas. Computer-implemented algorithms can detect position-orientation and force-torque at landmark points for a given object set. The result is a modular sensing system that is highly scalable in terms of price, quantity, size and applications. Such skin technology and associated software can comprise a sensing package that integrates tactile and visual data with accompanying software for state estimation, situational awareness, and automatic control of machinery. The addition of tactile data can serve to constrain and/or augment visual pose estimation methods as well as provide pose estimation to visually occluded objects.

  • Patent number: 9805299
    Abstract: A radio-frequency identification tag that includes a ground plane made of an electrically conductive material, and an actuator made of a transducer material adapted to convert a variation of a physical quantity into a mechanical displacement of the ground plane between first and second positions when the physical quantity crosses a predetermined threshold in order to indicate this event to the reader. The transducer material is a thermal shape-memory material or a magnetostrictive material or a magnetic shape-memory material. The transducer material is also an electrically conductive material. The ground plane and the actuator are both formed by a single strip made of the transducer material and a mobile portion of which moves relative to an antenna between the first and second positions when the physical variable crosses the predetermined threshold.

  • Patent number: 9678051
    Abstract: The present invention is a method for distinguishing, classifying and measuring soft and hard inclusions in a liquid metal that includes obtaining a flow through cell disposed on a tube with a top to allow the liquid metal to flow through the flow through cell and into the tube. There is also a mounting and a vacuum system disposed on top of the tube to draw the liquid metal through the flow through cell and into the tube that utilizes a pair of electrodes set inside and outside of the tube to apply an electric current to the liquid metal passing through the flow through cell. An electric resistance change is then measured and an electric resistance pulse is applied to the liquid metal to measure deformed behavior of the inclusions. The resistance pulse method can be used with liquid droplets, steel slag, bubbles and other deformable inclusions.
