  • Patent number: 12073024
    Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to detecting that a representation of a finger is located by a first input element: obtaining information regarding a first amount of force to actuate the first input element, and causing adjustment of a physical characteristic of an actuator so that a first amount of force directed to a component of the actuator activates the first input element. In response to detecting that the representation of the finger is located by a second input element, the method also includes: obtaining information regarding a second amount of force distinct from the first amount of force, and causing adjustment of the physical characteristic of the actuator so that the second amount of force directed to the component of the actuator activates the second input element.

  • Patent number: 10745164
    Abstract: Provided herein are solutions to automated material handling comprising systems that allow automated “each pick handling” without requiring the complexity of robotic grasping. Numerous examples of pre-configurable and reconfigurable transport containers, partitioning devices, and automated container configuration stations are described in addition to methods of use and associated material handling systems that utilize such containers. Further described are containers that are individually configured or customized according to specific lot sizes to more efficiently and optimally contain, store and distribute articles as a component of a picking system. Configurable containers or “totes” may be customized on a per-order basis to create optimally configured containers that maximize the use of space in a container, on a single-item-per-space basis, regardless of item quantity, size or volume, by customizing the size of each space within a container or tote.

  • Patent number: 10421613
    Abstract: A system to sort packages or parcels into chutes includes a package and parcel transporting component with a plurality of zones, each coupled to an electroadhesive material. The package and parcel transporting component is operable to move the plurality of zones. The electroadhesive material includes electrodes to exert an electroadhesive force and dynamically electrically couple to be energized by an applied voltage on demand. The system includes a controller to determine chutes into which to release packages or parcels and determine zones associated with packages or parcels. The controller selects zones associated with the packages or parcels to transport or release packages or parcels. The controller operates the electrodes to alter the electroadhesive material in the zones associated packages or parcels to transport and release the packages or parcels to one or more chutes.

  • Patent number: 10232383
    Abstract: A process for sorting materials using material-selective electroadhesive grippers is disclosed. At least one of an electroadhesive surface or a plurality of articles is manipulated such that multiple ones of the plurality of articles are at least intermittently proximate the electroadhesive surface. Voltage is applied to one or more electrodes in the electroadhesive surface to thereby cause the electroadhesive surface to selectively adhere to a subset of the plurality of articles based on the subset of the plurality of articles having different material properties than others of the plurality of articles. While the voltage is applied, the electroadhesive surface is moved with respect to the others of the plurality of articles to thereby separate the subset of the plurality of articles from the others of the plurality of articles.

  • Patent number: 10065326
    Abstract: Acquisition or pick-up tools that themselves aid in improving the ease with which images of an acquired substrate may be captured, and methods of operating such pick-up tools, are provided. The pick-up tools may include a pick-up surface adapted to interface with a foreign substrate and a light source integrated with the pick-up tool such that light emitted from the light source passes through the pick-up surface to the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface to create a silhouette of the foreign substrate. A vision system may be adapted for capturing the silhouette of the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface. The substrate pick-up surface may be formed of one of a transparent, a semi-transparent, or a translucent material such that light may at least partially pass there through.
