Filed:

Jul 17, 2000

Appl. No.:

09/618137

Inventors:

Tu Chen - Monte Sereno CA

International Classification:

G11B 566

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:

C08L 2300

US Classification:

525191, 525221, 525222, 525240

Abstract:

The present invention relates to compositions and preparative process of partially or fully neutralized mixtures of carboxylate functionalized ethylene high copolymers or terpolymers (Mw between 80,000 and 500,000) with carboxylate functionalized ethylene low copolymers (Mw between 2,000 and 30,000) and organic acid salts and injection or compression molded applications such as golf ball components thereof.

Abstract:

Thermoplastics with high resilience (high coefficient of restitution) and softness (low Atti compressions) and their use in golf ball components. Melt-processible, highly-neutralized ethylene acid copolymers and process for making them by incorporating an aliphatic, mono-functional organic acid in the acid copolymer and then neutralizing greater than 90% of all the acid groups present.

US Classification:

382164, 382173, 382242

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.
