US Classification:

2041922, 427128, 427129, 427130, 427131, 428694 T, 428900

Abstract:

A Co-Pt based magnetic alloy which has been doped with a relatively high amount of nitrogen, e. g. , or above 1 at. % is obtained having high coercivity, for example in the range of 1400 Oe or above, and an increased signal-to-noise ratio as compared to the same Co-Pt based alloy which has not been doped with nitrogen. The alloy is vacuum deposited, for example, by sputtering, and the nitrogen may be introduced from the sputtering gas or from the sputtering target. Other low-solubility elements providing the grain uniformity and isolation include: B, P, S, C, Si, As, Se and Te.

Abstract:

A repeater, useable for connecting switches in a data communication network, is provided in a distributed and/or modular fashion. The repeater includes a plurality of separate and distinct components or modules connected to or at least partially housed in, the various switches which the repeater modules couple. The distributed and/or modular repeater facilitates accommodating various switching or repeater needs as a network grows or contracts. A light pipe, preferably integral with a module case, conveys indicator lights to a position visible when viewing a switch front panel. A heat spreader unit receives and/or conveys heat and/or protects against undue EMI. A collision-handling state machine transmits modified collision fragments so as to avoid reduction in interpacket gaps, e. g. by downstream repeater modules.

International Classification:

H01R 13514

US Classification:

439701, 439676

Abstract:

A modular connector having a housing with one or more compartments, each compartment being structured and arranged to receive a plug. Within the housing are one or more conductive planes. Preferably, there are two conductive planes, a voltage source plane and a voltage ground plane. These source and ground planes are provided on a printed circuit board within the housing. The source and ground planes create a low impedance path for the source and ground connections by directly connecting the source and ground planes to a system printed circuit board of the equipment unit by a common voltage source pin and a common voltage ground pin, each of which extend from the housing. The voltage source connections and the voltage ground connections for each RJ jack are respectively connected to the voltage source plane and the voltage ground plane such that each of the RJ jacks share a common voltage source and ground. Accordingly, when multiport RJ connectors are formed, the use of the common source and ground planes operates to reduce the number of pins in each RJ unit by requiring only one voltage source pin and one voltage ground pin regardless of the number of RJ jacks in the multiport connector.

Abstract:

An image segmenter uses one or more techniques to accurately segment an image, including the use of a progressive flood fill to fill incompletely bounded segments, the use of a plurality of scaled transformations and guiding segmentation at one scale with segmentation results from another scale, detecting edges using a composite image that is a composite of multiple color planes, generating edge chains using multiple classes of edge pixels, generating edge chains using the plurality of scaled transformations, and/or filtering spurious edges at one scale based on edges detected at another scale.
