Patent number: 12355723Abstract: Methods and related systems are presented that relate to automatically avoiding address conflicts when establishing a secure communications link over a public network between a local computer, associated with a local network, and a remote device, located outside the local network. Local network addresses on the local network reserved for use, and a block of local network addresses that do not conflict with the reserved local network addresses, are identified. At least one local network address is selected from the block and assigned as an address of the local device for use in communicating with the remote device securely over the public network. Communication is facilitated with the remote device using the network driver based on the assigned at least one local network address.Type: GrantFiled: March 25, 2022Date of Patent: July 8, 2025Assignee: VirnetX, Inc.Inventors: Robert Dunham Short, III, Michael Williamson, Victor Larson

Publication number: 20250149819Abstract: A modular electrical connector with modular components suitable for assembly into a right angle connector may also be used in forming an orthogonal connector or connector in other desired configurations. The connector modules may be configured through the user of extender modules. Those connector modules may be held together as a right angle connector with a front housing portion, which, in some embodiments, may be shaped differently depending on whether the connector modules are used to form a right angle connector or an orthogonal connector. When designed to form an orthogonal connector, the extender modules may interlock into subarrays, which may be held to other connector components through the use of an extender shell. The mating contact portions on the extender modules may be such that a right angle connector, similarly made with connector modules, may directly mate with the orthogonal connector.Type: ApplicationFiled: January 13, 2025Publication date: May 8, 2025Applicant: Amphenol CorporationInventors: Allan Astbury, John Robert Dunham, Marc B. Cartier, JR., Mark W. Gailus, Daniel B. Provencher

Publication number: 20250141160Abstract: A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.Type: ApplicationFiled: December 6, 2024Publication date: May 1, 2025Applicant: Amphenol CorporationInventors: Marc B.

Publication number: 20250038435Abstract: A modular high speed, high density electrical connector configurable for use in multiple configurations, including a direct attach orthogonal configuration. The connector is assembled with modules that include shielded pairs of signal conductors with mating ends that are rotated approximately 45 degrees with respect to intermediate portions of the signal conductors. The connector may have a mating interface with receptacles in one connector and pins in the mating connector. The pins may be small diameter and may be implemented with superelastic wires so as to resist damage despite having very small effective diameter. A compact mating interface resulting from small diameter mating contact portions may enable other portions of the connector, including the shielding surrounding the signal conductors to be smaller, which may raise the resonant frequency of the connector and extend its bandwidth.Type: ApplicationFiled: August 2, 2024Publication date: January 30, 2025Applicant: Amphenol CorporationInventors: Marc B.

Publication number: 20240291814Abstract: Systems and methods are provided for establishing a secure communication link between a first client and a second client. One exemplary computer-implemented method for establishing a secure communication link between a first diem and a second client includes accessing, from a storage, identification information of a user of the first client. The method further includes receiving a Domain Name Service (DNS) request from the first client requesting a secure network address corresponding to a secure domain name associated with the second client. The method further includes authenticating the user based on the user identification information. The method also includes transmitting the secure computer network address in response to the DNS request based on a determination that the user has been authenticated. A secure communication link between the first diem and the second client is established based on the secure computer network address.Type: ApplicationFiled: March 4, 2024Publication date: August 29, 2024Applicant: VirnetX, Inc.Inventors: Robert Dunham Short III, Nathaniel Jackson Short, Michael Glenn Williamson

Publication number: 20240014609Abstract: A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector may be assembled with multiple subassemblies, each of which may have multiple pairs of signal conductors. The subassemblies may be formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, may establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material may be positioned between the pairs in a subassembly and/or may contact the reference conductors of the subassemblies, and the lossy material of the subassemblies may in turn be connected with a conductive structure.Type: ApplicationFiled: May 12, 2023Publication date: January 11, 2024Inventors: Marc B.

Publication number: 20230420874Abstract: An electrical interconnect for passing high speed signals through an electronic system with a high density of signals and high signal integrity. The interconnect includes an electrical connector and a transition portion of a printed circuit board to which the connector is mounted. Signal conductors are connected to pads on the surface of the PCB using edge-to-pad mounting. The pads align with intermediate portions of the signal conductors such that transitions within the connector that could degrade signal integrity are avoided. The signal conductors may be positioned as individually shielded broadside coupled pairs extending in rows within the connector. Surface traces on the PCB connect the pads to signal vias aligned for vertical routing out of the connector footprint. Ground planes underlying the surface traces facilitate a transition from the signal paths in the connector to those in the PCB with low mode conversion avoiding resonances in the connector shields.Type: ApplicationFiled: April 24, 2023Publication date: December 28, 2023Applicant: Amphenol CorporationInventors: John Robert Dunham, Marc B.

Patent number: 11824311Abstract: A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.Type: GrantFiled: June 21, 2021Date of Patent: November 21, 2023Assignee: Amphenol CorporationInventors: Mark W.
