Patent number: 11922366Abstract: Provided are systems and processes for optimizing assignments of deliveries for perishable goods. In one aspect, a method is provided for pairing a set of created orders with a set of available couriers. The set of created orders may include orders confirmed by the merchant and the set of available couriers include couriers that are online with an active status. Feasible pairings are generated between each courier and each created order. Infeasible pairings are eliminated based on factors such as transportation mode. Possible routes for each pairing are generated and scored based on weighted factors. The scores are optimized to achieve a set of routes with a maximum score. The routes are then offered to the corresponding courier if the courier will arrive at or after the created order is completed by the merchant. A neural network may be implemented to recognize the optimal score for a given duration.Type: GrantFiled: February 3, 2022Date of Patent: March 5, 2024Assignee: DoorDash, Inc.Inventors: Rohan Balraj Chopra, Richard Hwang, Jeff Ning Han

Publication number: 20210166318Abstract: The invention relates to an engine that generates client profile-based sales decisions. An embodiment of the present invention is directed to providing new insights to strengthen opportunities to provide additional services to clients. The system is directed to developing client profile-based recommendations for trade ideas. For example, the innovative engine may recommend opportunities, such as new trade ideas, to a particular client based upon the client's transaction history, as well as other data and factors. The system may generate an account profile based upon client data and use this profile to score a potential new trade idea.Type: ApplicationFiled: June 3, 2016Publication date: June 3, 2021Inventors: John TANG, Ashleigh Ann THOMPSON, Benjamin F.

Patent number: 9690323Abstract: A portable electronic device includes a main body, a protective foldable cover, a membrane keyboard and a folding means. The protective foldable cover is attached structurally in a foldable manner to the main body and further has a foldable leaf to cover the main body. The membrane keyboard is mounted to the foldable leaf by facing the main body and is connected signally with the main body. The folding means is to provide at least one stand state for the main body to stand on the foldable leaf of the protective foldable cover and thus to present the membrane keyboard completely to a position in front of the main body.Type: GrantFiled: May 11, 2016Date of Patent: June 27, 2017Inventor: Richard Hwang

Patent number: 9662443Abstract: An alert device for use with an intravenous drip, comprises two induction ends and a control unit. The control unit comprises a circuit module, an alarm module and a power module. The two induction ends are located on a pipe of the intravenous drip and are contacting with an injection solution inside the pipe. The two induction ends are electrically connected to the control unit by wires. The circuit module detects the induction ends to determine whether the induction ends are in an open-loop status or not. The circuit module connects to the alarm module. The power module supplies power for the control unit. The induction ends uses the injection solution as a conducting means to form an electrically closed loop; when the induction ends do not contact with the injection solution, the induction ends become an open-loop, and thus the alarm module generates alarm signals.Type: GrantFiled: January 6, 2014Date of Patent: May 30, 2017Inventor: Richard Hwang

Publication number: 20170103296Abstract: A wireless input device comprises a plurality of RFID tag units and keys. Each RFID tag unit is coupled with two conductive wires. Only when the two conductive wires are in a closed-loop status, the RFID tag unit can generate a responsive RF signal corresponding to a scanning signal generated by a host device. Each key is formed with a switching mechanism connectable to the conductive wires of at least one of the RFID tag units. When any one of the keys is pressed, the conductive wires connectable to the pressed key will be switched to the closed-loop status from an open-loop status, and when that pressed key is released, the conductive wires connectable to the released key will be switched back to said open-loop status. Therefore, the wireless input device can be operated without the need of internal electric power.Type: ApplicationFiled: October 7, 2015Publication date: April 13, 2017Inventors: Richard Hwang, Memiee L.

Publication number: 20170020493Abstract: An organism paracentesis device comprises a first tube member and a second tube member. The first tube member comprises an injection tube filled with a medicament, a piston and a first syringe needle. The second tube member comprises a sampling tube and a second syringe needle. Both ends of the second syringe needle are in the form of syringe needle. Using one end of the second syringe needle to penetrate a cover of the sampling tube which is vacuumed, such that the second syringe needle's the other end which is penetrating into an organism will extract a sample from the organism because of the vacuumed sampling tube. The medicament filled in the injection tube is ejected both when the first and second syringe needles are penetrating into and pulled out of the organism, so as to avoid the cells of sampled organism being spread to other places.Type: ApplicationFiled: September 30, 2016Publication date: January 26, 2017Inventor: Richard Hwang

Publication number: 20160101140Abstract: A method for processing rosaceous kernels includes the steps of preparing a predetermined amount of rosaceous kernels, heating the rosaceous kernels to a predetermined temperature range for a predetermined time, lowering a temperature of the rosaceous kernels to a normal temperature, and making the rosaceous kernels edible for users to intake Vit B17 contained in the rosaceous kernels. Through the heating process, the beta-glucosidase contained in the rosaceous kernels can be destroyed completely, but the Vit B17 still stays in the rosaceous kernels.Type: ApplicationFiled: October 15, 2014Publication date: April 14, 2016Inventor: Richard Hwang

Patent number: 9258396Abstract: A hand-held electronic device having a rolled-up screen comprises a flexible screen which can be partially received within a casing by a reeling mechanism in such a manner that the displaying function can still be performed by the flexible screen partially exposed outside the casing. When the flexible screen is pulled out and entirely exposed outside of the casing, the entire flexible screen can be used for image-displaying. Thus, advantages in both the high displaying quality of a large screen and excellent portability of a small-sized hand-held electronic device can be attained.Type: GrantFiled: January 6, 2014Date of Patent: February 9, 2016Inventor: Richard Hwang
