International Classification:

G11B 5/127

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.

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.

International Classification:

H04N 7/173

US Classification:

725110

Abstract:

System(s), method(s), and device(s) providing converged wireline and wireless services in part by employing a set-top box (STB) with machine-to-machine (M2M) communication are presented. The STB, associated with an access point, such as a femtocell, can be used to send/receive messages, including video, to/from user equipment (UE) via a core network. A monitoring system includes a sensor component that is triggered under specified conditions, and the STB records events in response to the trigger, where a recorded event can be sent as a message to the UE. The STB or associated remote control can indicate a received message to a user, who can view the message on the STB, remote control, or associated television. A meter component is associated with the STB via the femtocell or other desired connection. The STB can receive and store utility meter readings for validation or dispute by the user.

International Classification:

G06F 11/00

US Classification:

370225

Abstract:

System(s), apparatus(es), and method(s) are provided to for providing femtocell service through a secondary connection to a network gateway node that is part of a service provider network. The secondary connection can be established in response to at least one telecommunication performance condition of a primary connection to the network gateway node; the at least one performance condition includes connectivity state of the primary connection or quality of traffic delivery through the primary connection. The secondary connection can be established, in part, via a home gateway node that is alternative to a home gateway node associated with a femtocell access point (AP) that enables, in part, the femtocell wireless service. The main home gateway node or the femtocell AP can initiate establishment of the secondary connection. Home gateway node(s) or femtocell AP(s) that can provide femtocell service through the secondary connection can manage connectivity with the network gateway node.

Abstract:

The present application provides immune cells (such as T cells) comprising a chimeric antibody-T cell receptor (TCR) construct (caTCR) and a secretory secondary effector (SSE) construct. The caTCR comprises an antigen-binding module that specifically binds to a target antigen and a T cell receptor module (TCRM) capable of recruiting at least one TCR-associated signaling molecule, and the SSE is capable of enhancing an immune response mediated by the caTCR. Also provided are methods of making and using these cells.
