Abstract: A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion and edge coupled end portions. Broadside coupling provides balanced pairs for very high frequency operation, while edge coupling provides a high density interconnection system at low cost. Each module has separately shielded signal conductor pairs. The shielding is shaped to avoid or suppress undesirable propagation modes within an enclosure formed by shielding per module. Lossy material is selectively placed within and outside the shielding per module to likewise avoid or suppress unwanted signal propagation.

Abstract: A modular electrical connector with separately shielded signal conductor pairs. In some embodiments, the connector is assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. In some embodiments, the modules have projecting portions, of conductive and/or dielectric material, that are shaped and positioned to reduce changes in impedance along the signal paths as a function of separation of conductive elements, when the connectors are separated by less than the functional mating range.

Abstract: An electrical connector designed for high speed signals. The connector includes one or more features that, when used alone or in combination, extend performance to higher speeds. These features may include compensation for tie bars that are used to hold conductive members in place for molding a housing around the conductive members. Removal of the tie bars during manufacture of the connector may leave artifacts in the conductive members and/or housing, which may degrade electrical performance. However, that degradation may be avoided by features that compensate for the artifacts. The conductive members, for example, may include regions, adjacent tie bar locations, that compensate for portions of the tie bar that are not fully removed.

Abstract: 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 client 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 client and the second client is established based on the secure computer network address.

Abstract: A direct-connect orthogonal electrical connection system with improved high frequency performance is provided. A conductive member is provided between first and second components, each having signal and ground conductors. The conductive member is electrically coupled to ground conductors of both the first and second components and may also have openings through which signal conductors of the first and second components may connect. As such, signal conductors may be positioned relative to the conductive member such that a uniform impedance is maintained along a signal path throughout the interconnection, reducing noise and reflections. The signal conductors may be formed with multiple beams of different lengths to create multiple points of contact distributed along an elongated dimension. For example, a third beam may be fused to a mating portion to allow a tolerance for deviations in alignment between two directly connected connectors.

Abstract: 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.

Abstract: A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to “hopping” of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes.
