Publication number: 20240004356Abstract: Embodiments of the present disclosure provide functionality for creating a sustainable dynamic reduced-order model (SDROM) for operating a real-world industrial process. The model is based upon a reduced order model (ROM) trained using data obtained from simulations performed using a first-principles model (FPM) of the real-world industrial process. The trained ROM is divided into multiple-input, single-output (MISO) sub-models, which are partitioned into component terms for incorporation of respective gain factors. The SDROM is deployed online to operate the real-world industrial process with one or more optimization objectives and the SDROM is periodically calibrated and validated using historical operation data.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Inventors: Hong Zhao, Christopher Quan, Shu Wang, Melisa Morales Cárdenas

Patent number: 11101020Abstract: Computer-implemented methods of characterizing chemical composition of a sample containing crude oil or a petroleum fraction are presented. The methods can include, in a processor, receiving assay data of the sample, and particularly molecular-level data obtained using advanced analytical techniques, and processing this data in view of a model library of compounds, including reconciling compound compositions, to form a characterization of the chemical composition of the sample.Type: GrantFiled: April 24, 2018Date of Patent: August 24, 2021Assignee: ASPEN TECHNOLOGY, INC.Inventors: Suphat Watanasiri, Shu Wang, Lili Yu, Christopher Quan

Patent number: 10719801Abstract: An inventory receptacle can include a body that includes a plurality of walls arranged to at least partially bound a storage volume. A computer-readable identifier connected with the body may be associated with an electronically-stored record about items registered as being present in the storage volume. A cover may be detachably coupled with the body so as to at least partially bound the storage volume in an arrangement that blocks access to the computer-readable identifier and to the storage volume. The cover may be configured for detachment from the body so as to allow access to the computer-readable identifier and the storage volume.Type: GrantFiled: September 30, 2016Date of Patent: July 21, 2020Assignee: Amazon Technologies, Inc.Inventor: Adrian Christopher Quan

Publication number: 20190093777Abstract: Fluid & Gas Purged & Injected Safely is a product that allows the end-user to either purge or inject fluids and gases into mechanical systems without exceeding the systems designed limits. The built-in adjustable pressure relief valve is set in the field by the user, or is factory set, to release excess pressure before it exceeds the engineered design. This safety precaution product prevents stresses on mechanical systems, which in many cases go unnoticed. System failures due to over pressurizing a system have caused serious injuries and deaths in the moment of the design breach and after the fact. In some cases: it can take years for a concealed section of a mechanical system to reveal there is a problem and by that time there are irreparable structural damages, adverse health issues, and in worse cases death.Type: ApplicationFiled: December 11, 2017Publication date: March 28, 2019Applicant: Water Heater DepleterInventor: Jason Christopher Quan

Patent number: 10163071Abstract: Techniques for providing a removable and reusable tracking device feature in an inventory management system may be described. For example, the inventory management system may associate a reusable tracking device with an item based on first identification information from the reusable tracking device and second identification information from the item in response to an inventory transfer request for the item. Instructions may be provided to attach the reusable tracking device to the item and deliver the item and the associated reusable tracking device to a user based on the inventory transfer request for the item. A notification may be generated based on a signal received from the reusable tracking device. The notification may be provided to a user device of the user and indicate that a subsequent order for the item should be placed on behalf of the user.Type: GrantFiled: September 24, 2015Date of Patent: December 25, 2018Assignee: Amazon Technologies, Inc.Inventors: Adrian Christopher Quan, Kimberly Anne Lewis, Jamie Marie Holland, Allan Scott Bathurst, Wesley Scott Lauka, Ryan Scott Russell

Publication number: 20180002734Abstract: This invention relates to methods for molecular detection, particularly to methods utilizing target-specific molecular probes. In exemplary embodiments, target-specific molecular probes include single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) aptamers. In general, the molecular probe may bind with relatively high specificity to a given target. In one aspect, a method for molecular detection comprises a molecular probe paired to a reporter molecule wherein the molecular probe impairs the amplification of the reporter molecule in the absence of the target molecule.Type: ApplicationFiled: June 27, 2017Publication date: January 4, 2018Inventors: George Jackson, Christopher Quan

Patent number: 9715674Abstract: Features are disclosed for using location awareness, bin capacity, and environmental cues to provide in context guidance to the associate when stowing items such as at a fulfillment center. In accordance with aspects of the present disclosure, the associate may scan an item he or she may want to stow. In response, lights on the bins in the associate's vicinity are illuminated to indicate bins in which the item can be stowed (e.g., because the item fits in the bin) without breaking stow etiquette. For example, in order to prevent mix up, stow etiquette may indicate that two types of erasers should not be stored in the same bin. As yet another example, stow etiquette may indicate that an item should not be stowed in a bin, even if it fits and there is room, so that a total weight for the bin is not exceeded.Type: GrantFiled: March 20, 2017Date of Patent: July 25, 2017Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Adrian Christopher Quan, Jamie Marie Holland, Kimberly Anne Lewis, Benjamin Lee Farrow

Patent number: 9552569Abstract: Techniques for providing a removable and reusable tracking device feature in an inventory management system may be described. For example, an inventory transfer request may be received for transferring inventory within a facility. A first indication may be received that indicates one or more reusable tracking devices are associated with the inventory included in the inventory transfer request. Information about the inventory transfer request may be mapped to the association of the one or more reusable tracking devices and the inventory. In an embodiment, a location of the inventory may be determined based on location information provided by the associated one or more reusable tracking devices. The mapping between the inventory transfer information to the one or more reusable tracking devices and the inventory may be removed based at least in part on the location information indicating that the inventory is located at a particular location within the facility.Type: GrantFiled: September 24, 2015Date of Patent: January 24, 2017Assignee: Amazon Technologies, Inc.Inventors: Adrian Christopher Quan, Kimberly Anne Lewis, Jamie Marie Holland, Allan Scott Bathurst, Wesley Scott Lauka, Ryan Scott Russell
