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:

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.

Cheng Liu - Richmond CA, US

International Classification:

G01N 33/574
G01N 33/566

US Classification:

435 723, 435 72

Abstract:

Methods for detecting antibody dependent cellular cytotoxicity (ADCC) are described herein. The methods are label-free, and can be performed in real time on adherent cells. The methods can include, for example, (a) monitoring the impedance between electrodes on a non-conducting substrate that supports the growth of target cells in an assay medium; and (b) adding effector cells and an antibody that binds to the target cells to the assay medium; wherein any decrease in the impedance between the electrodes on the substrate following addition of the effector cells and the antibody is indicative of ADCC function having been effected in the assay medium.

International Classification:

G06F 15/00

US Classification:

702190

Abstract:

One example embodiment includes a testing device. The testing device comprises a signal reception element, an out-of-band detector and testing logic. The signal reception element is configured to receive a physical layer signal from a communication module via a physical link and to produce an incoming double modulated signal, the incoming double modulated signal including a high-speed data signal and an out-of-band data signal. The out-of-band data signal comprises diagnostic data of the communication module. The out-of-band detector is coupled to the signal reception element and is configured to extract the out-of-band data signal from the incoming double modulated signal. The testing logic is coupled to the out-of-band detector and is configured to extract and analyze the diagnostic data from the out-of-band data signal.
