Patent number: 11100460Abstract: A system for replenishing a pick face includes a storage and retrieval machine (SRM) that traverses an aisle of a warehouse and monitors a replenishment position of each pick location of a pick face. The SRM transmits a message to the system indicating which ones of the replenishment positions are empty. The SRM delivers a replenishment load to a pick location that is indicated as empty in the message. Each pick location includes a flow lane configured to direct the motion of package loads sliding down to a picking position of the pick face. The flow lane includes a lever arm assembly that constrains and brakes the motion of package loads sliding down the flow lane. A bar stop of the lever arm assembly constrains a replenishment load, while a retainer bar of the lever arm assembly constrains a forward load. The replenishment load is behind the forward load.Type: GrantFiled: March 22, 2019Date of Patent: August 24, 2021Assignee: Dematic Corp.Inventors: Criston S. Stevens, Christopher Blackburn, Paul K. Gines, Max Weston

Patent number: 10472845Abstract: A fastener for fastening parts together. The fastener has a shaft, a head and movable members that spring outwardly from the shaft to firmly capture the parts between the members and the head upon insertion of the fastener into aligned holes in the parts. No threading step is necessary. The movable members may be retractable into the shaft to facilitate insertion into holes corresponding in size to the shaft. The members may have a contact surface sloping away from the head and forming a tapered space between the members and the head so that the outward spring bias tends to reduce the space and maintain tightness of the joint. The fastener may be operatively deployed by a single insertion step.Type: GrantFiled: December 18, 2015Date of Patent: November 12, 2019Assignee: Infinigy Solutions, LLCInventors: John S.

Patent number: 10400105Abstract: Extruded starch foams are well known as biodegradable alternatives to foamed polystyrene packaging materials. Extruded foams of unmodified starch replacing 1% to 20% of the starch with kraft lignin were prepared. At 10% lignin, there are no deleterious effects on foam density, morphology, compressive strength, or resiliency as compared to a starch extruded foam, yet the foam retains its integrity after immersion for 24 hours in water. At 20% lignin there is a decrease in compressive strength and resiliency. Addition of cellulose fibers restore the mechanical properties but with an increase in density.Type: GrantFiled: June 10, 2016Date of Patent: September 3, 2019Assignee: The Research Foundation for The State University of New YorkInventor: Eugene S. Stevens

Patent number: 10393024Abstract: A multi-air stream cooling system is provided. The multi-air stream cooling system may comprise an inner vane support, a flow guide, and a fastened inner duct. The inner vane support may partially define a first airflow path. The flow guide may couple to the inner vane support and may partially define a second airflow path. The fastened inner duct may couple to the flow guide and may partially define a third airflow path. The inner vane support may comprise a discharge slot to allow a first airflow into a blade rim cavity. The flow guide may comprise a tangential onboard injector (TOBI) to provide a second airflow through a cover plate. The flow guide may also comprise a bypass passage configured to enable a third airflow from the third airflow path.Type: GrantFiled: August 29, 2016Date of Patent: August 27, 2019Assignee: United Technologies CorporationInventors: Michael S.

Patent number: 10310994Abstract: A sequential asynchronous system and a method for operating the same. The method includes operating a first asynchronous finite state machine at a first clock rate and operating a second asynchronous finite state machine at a second clock rate. The method also includes generating, with fork logic, a fork request based on a first state of the first asynchronous finite state machine and receiving, with join logic, the fork request from the fork logic. The method further includes receiving, with the join logic, a communication request from the second asynchronous finite state machine based on a second state of the second asynchronous finite state machine and initiating, with the join logic, a state transition of the second asynchronous finite state machine. The method also includes providing, with the join logic, a join acknowledgement to the fork logic upon completion of the state transition.Type: GrantFiled: February 28, 2017Date of Patent: June 4, 2019Assignee: UNIVERSITY OF UTAH RESEARCH FOUNDATIONInventors: Kenneth S.

Patent number: 10301113Abstract: A method of filling orders and order fulfillment system includes storing inventory receptacles in an automated warehouse, some having a plurality of different types of inventory items. A queue of orders is maintained in a computer system, each including at least one inventory item. Each order is selected from the queue and assigned to a pick station. The computer system retrieves inventory receptacle(s) from the automated warehouse for the selected order and supplies the receptacle(s) to the pick station. The computer system identifies to an operator which inventory item is to be segregated with the selected order in at least one put receptacle. One or more of the put receptacles receives inventory items for at least one individual order and is directed to a secondary order processing station where items are separated into individual orders.Type: GrantFiled: February 16, 2017Date of Patent: May 28, 2019Assignee: Dematic Corp.Inventors: Criston S.
