International Classification:

G11B 5/127
G11B 21/21
G11B 5/39

US Classification:

360323, 3602353, 2960314

Abstract:

According to an embodiment of the present invention, a slider design is presented that provides improved protection for the head/sensor of the slider. In one embodiment, the design of the slider is such that ESD protection is provided during the slider wafer process, the “back-end” processes (e. g. , when the completed slider/head is incorporated into an HGA), and during operation in a disk drive or the like. In this embodiment, a conductive film is provided that surrounds the insulating-material slider substrate. The conductive film provides a grounding path during the wafer fabrication processes. This conductive layer may be further patterned during head fabrication to provide a ground path for back-end fabrication processes. A conductive stripe may be added for discharging debris in the slider-to-disk interface.

US Classification:

455558, 455415, 455418, 4554351

Abstract:

Systems, methods, and computer program products are for managing access to a femtocell coverage area. An exemplary method includes storing in a memory component a first identifier corresponding to a subscribed service of a communication device and a second identifier corresponding to a user of the communication device, and granting access to the femtocell coverage area using the second identifier.

US Classification:

370394, 370219, 370243, 370244, 370401

Abstract:

Systems and methods are disclosed for synchronizing sequence numbers in a packet flow. One such method includes receiving a sequence number synchronization request from a redundancy peer. The sequence number synchronization request is associated with a packet flow. The method also includes incrementing by a fixed amount a packet sequence number for the packet flow, after the sequence number synchronization request. The method also includes transmitting a next packet including the incremented packet sequence number to the communication peer.

US Classification:

514440000, 435248000, 435261000, 549037000

Abstract:

This invention relates to dietary compositions and to methods for modifying cellular metabolism, metabolic production of reactive oxygen species and the resulting level of reactive oxygen species. The invention is drawn to a composition comprising a combination of carnitine, lipoic acid and polyphenol, which has the effect of enhancing metabolism and reducing oxygen species at the same time. When the composition is fed to older animals, the animals will have improved metabolism at the cellular level and a reduction of oxidative stress. The invention is also drawn to a method of oral administration of carnitine, lipoic acid and polyphenol to a mammalian host, at an effective dose necessary to affect enhanced metabolic processes and reduced oxygen species in animals including humans.
