Patent number: 11943060Abstract: Methods and systems for managing an error correction mode at a first communications router. The first communication router transmits data packets to a second communications router and stores the first data packet in a local storage medium. When a delay inquiry message is received from the second communications router, the first communications router activates the error correction mode. When the error correction mode is activated, the first data packet is retransmitted to the second communications router and an error correction packet corresponding to the first data packet is also transmitted. When a back-to-normal message is received from the second communications router, the first communications router deactivates the error correction mode. The back-to-normal message indicates that the first communications router no longer needs to be in error correction mode.Type: GrantFiled: June 12, 2023Date of Patent: March 26, 2024Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Ho Ming Chan

Patent number: 11799686Abstract: The present invention discloses methods and systems for sending information packets from a first network node to a second network node. An aggregated tunnel is established between the first network node and the second network node. An information packet is determined whether to be sent according to profile condition(s) of the aggregated tunnel and then according to a selected policy. When a selected policy is selected and the information packet is sent through a tunnel according to the selected policy. When no policy is selected, the information packet is sent through one of a first group of tunnels. When no profile is selected, the information packet is sent through a network interface of the first network node.Type: GrantFiled: November 9, 2020Date of Patent: October 24, 2023Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Wan Chun Leung, Ho Ming Chan

Publication number: 20230263849Abstract: The efficacy in the use of probiotics is compromised due to their lack of survivability in gastric conditions (pH 1.5-3), leading to a large reduction in viable probiotic cells. The present disclosure describes cellulose nanocrystals (CNCs) modified with ferulic acid (FA) and shellac (SH) to produce two types of new coating materials, which are environment friendly and harmless to humans. These coating materials were developed and utilized to formulate Pickering emulsions (W1/O/W2 and W/O) for probiotic encapsulation. Based on their pKa values, greater than pKa, carboxyl groups from the CNCFA and CNCSH based Pickering emulsions were deprotonated, inducing phase separation and allow yeast releasing. This system could be further investigated for functionalized food-based applications to deliver active substances, such as probiotics, at high pH. Such delivery systems can be applied to human, animal, and aquatic systems.Type: ApplicationFiled: February 24, 2023Publication date: August 24, 2023Inventors: Michael Kam Chiu Tam, Jiyoo Baek, Mohankandhasamy Ramasamy, Gun-Hee David Cho

Patent number: 11582814Abstract: A method and system for a first node to transmit packets to a second none, comprising receiving a packet from a local area network (LAN) interface, inspecting the packet; determining whether the packet satisfies at least one packet condition; transmitting the packet through a predefined tunnel if the packet satisfies the at least one packet condition; transmitting the packet through a second tunnel if the packet does not satisfy the at least one packet condition. The predefined tunnel is a first tunnel and is established before the packet is received by the first node. The second tunnel belongs to a first tunnel group or a second tunnel group. The first tunnel, the second tunnel and other tunnels may together form an aggregated connection. Further, the use of predefined tunnel may be based on whether the packets satisfy a session condition.Type: GrantFiled: July 20, 2020Date of Patent: February 14, 2023Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kit Wai Chau, Kam Chiu Ng, Wan Chun Leung, Ying Kwan, Martin Langmaid

Publication number: 20220311701Abstract: Described in example embodiments herein are methods and systems for implementing sending packets from a first network node to a second network node. Packets belonging to the same session may be sent through the same or different tunnels. The second network node processes packets belonging to the same session using the same core. In accordance with an example embodiment, the first network node informs the second network code the core to process the packets. Optionally, selection of core at the second network node is assisted by a core identity created by the first network based on the session. The core identity may be stored in the header or payload of the packets. In an example embodiment, the second network determines the core for processing packet belonging to the same session.Type: ApplicationFiled: June 13, 2022Publication date: September 29, 2022Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai SUNG, Kam Chiu Ng, Wan Chun Leung

Publication number: 20220263681Abstract: The present invention relates to methods and systems for transmitting and receiving data packets between a first network node and a second network node through a bonded connection. At the first network node, a data packet, a session identification of the data packet and a time value of the data packet are encapsulated in an encapsulating packet. The first network node sends the encapsulating packet from the first network node to the second network node through the bonded connection. The second network node then stores the encapsulating packet after receiving it and determines an expiration time of the encapsulating packet. When the expiration time of the encapsulating packet expired, the second network node dequeues the encapsulating packet and forwards the data packet according to destination of the data packet.Type: ApplicationFiled: February 7, 2022Publication date: August 18, 2022Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai SUNG, Kam Chiu NG, Wan Chun LEUNG

Patent number: 11249813Abstract: Roughly described, a task control system for managing multi-scale simulations receives a case/task list which identifies cases to be evaluated, at least one task for each of the cases, and dependencies among the tasks. A module allocates available processor cores to at least some of the tasks, constrained by the dependencies, and initiates execution of the tasks on allocated cores. A module, in response to completion of a particular one of the tasks, determines whether or not the result of the task warrants stopping or pruning tasks, and if so, then terminates or prunes one or more of the uncompleted tasks in the case/task list. A module also re-allocates available processor cores to pending not-yet-executing tasks in accordance with time required to complete the tasks and constrained by the dependencies, and initiates execution of the tasks on allocated cores.Type: GrantFiled: November 22, 2019Date of Patent: February 15, 2022Assignee: Synopsys, Inc.Inventors: Stephen Lee Smith, Michael C.
