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.

International Classification:

C07K 16/32
C07K 16/30

Abstract:

The present disclosure relates to an anti-WT-1/HLA/A2 antibody with enhanced antibody dependent cell-mediated cytotoxicity (ADCC) function due to altered Fc glycosylation. The antibody, which has reduced fucose and/or galactose, was compared to its normally glycosylated counterpart in binding assays, in vitro ADCC assays, and mesothelioma and leukemia therapeutic models and pharmacokinetic studies in mice. The antibody with normal glycosylation mediated ADCC against hematopoietic and solid tumor cells at concentrations below 1 μg/ml, but the reduced fucosylated antibody was about 5-10 fold more potent in vitro against multiple cancer cell lines, was more potent in vivo against JMN mesothelioma, and effective against SET2 AML and fresh ALL xenografts. ESKM had a shortened half-life (4.9 vs 6.5 days), but an identical biodistribution pattern in C57BL6/J mice. At therapeutic doses of ESKM, there was no difference in half-life or biodistribution in HLA-A2.1+ transgenic mice compared to the parent strain. Importantly, therapeutic doses of ESKM in these mice caused no depletion of total WBCs or hematopoietic stem cells, or pathologic tissue damage.
