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

Publication number: 20240080920Abstract: The present disclosure provides systems and methods which increase the throughput of a TCP-based communication between a first network node and a second network node. First, the first network node sent a first plurality of TCP segments to the second network node. Second, when the second network node receives a second plurality of TCP segments, which is all or part of the first plurality of the TCP segments, the second network node responds by sending one or more TCP acknowledgements to the first network node with the last sequence number of a last segment among all TCP segment within the second plurality of TCP segments. The present disclosure are able to increase the throughput of a TCP connection while decreasing its reliability.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Wan Chun Leung

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: 20230296526Abstract: Provided is a portable biosensor that includes a sample filter cartridge, a filter collector, an optical sphere, an electromagnetic radiation emitter, a photo-detector, a processor, a signal display, a vacuum pump, and a power supply. The sample filter cartridge selectively removes small molecules to minimize spectral interference in the detection signal. The sample is concentrated onto the filter collector and subjected to illumination by the electromagnetic radiation emitter, producing Raman-scattering. The optical sphere collects and distributes the Raman-scattering shifts, which then pass through a spectral filter to produce spectral filtered scattering, which is then reflected by the concave holographic flat-field grating onto the photo-detector. The data is displayed graphically to provide the Raman-scattering shift data. The data is compared with a database for sample identification. The device is contained within a housing that is small enough to be easily transported for field use.Type: ApplicationFiled: March 20, 2023Publication date: September 21, 2023Applicant: The United States of America, as represented by the Secretary of the NavyInventors: Kin Chiu Ng, Subrata Sanyal

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: 11092545Abstract: The present invention relates to the design, construction, and operation for a diode-turret. Exemplary embodiments comprise several tens of laser diodes to function as a multiple-line radiation source. The invention further describes the construction for a socket-turret; this socket-turret will flexibly fit any numbers (limited only by the number of sockets available) of laser diodes. The invention further describes two radiation coupling-optics for the output from the turret of laser-diodes, one with an integrating sphere and another with a collimating scope. One operation method allows its user to set for any number of diode, functioning one diode at a time, sequentially, hopping from one diode to another, as a single-line radiation source for the spectrometry. Another operation method permits its user to set a group with any number of diodes, functioning several diodes simultaneously at a time, as a multiple-line radiation source for spectrometry.Type: GrantFiled: July 17, 2020Date of Patent: August 17, 2021Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Kin Chiu Ng, Subrata Sanyal
