Patent number: 11399649Abstract: Package-receiving-lockers (PRLs) may have a collapsible-locker portion and door-attachment-structure. PRLs may exist in a substantially collapsed configuration for storing the given PRL or for otherwise minimizing a footprint of the given PRL; and these PRLs may exist in a substantially deployed (expanded) configuration for acting as a secure object storage location. Regardless of configuration (deployed or collapsed), PRLs may be removably attached to side-hinged-doors with the door-attachment-structure, in such a way so as not to impair operation of the given door. The PRLs may have various electronics for facilitating access (e.g., locking and unlocking the collapsible-locker), delivery confirmation, and mitigating theft. These electronics, along with specialized software, may allow an intended recipient (e.g., a buyer), a shipper/delivery person (or shipping/deliver robot), and/or a seller/vendor to access the PRL in a controlled and documented manner.Type: GrantFiled: July 3, 2020Date of Patent: August 2, 2022Assignee: Securum Capsa, Inc.Inventors: Carlos Raphael, Jason Scott Altman, Jeff Harlan

Method of determining a relative decrease in catalytic efficacy of a catalyst in a catalyst solution
Patent number: 11203651Abstract: The present disclosure provides a method of determining a relative decrease in catalytic efficacy of a catalyst in a test sample of a catalyst solution with unknown catalytic activity. The method includes (a) mixing the test sample with a test solvent to form a test mixture and (b) measuring the increase in the temperature of the test mixture at predetermined time intervals immediately after forming the test mixture. A predetermined feature is used to determine both a test value in the increase in temperature measured in (b) and a control value in a known increase in temperature of a control mixture of the test solvent with a control sample of a control catalyst solution. The relative decrease in catalytic efficacy of the catalyst in the test sample having the unknown catalytic activity is then determined from: Relative Decrease in Catalytic Efficacy=Control Value?Test Value/Control Value.Type: GrantFiled: June 1, 2018Date of Patent: December 21, 2021Assignee: Univation Technologies, LLCInventors: Ian M.
