20100142381 | MECHANISMS FOR FAILURE DETECTION AND MITIGATION IN A GATEWAY DEVICE - A system and method of the present disclosure provides a block, or region, based error diffusion process for reducing artifacts in images. The system and method allows for the generation and the control of the spatial frequency of a masking signal, e.g., noise, in a way that it can be easily passed through the compression process. The system and method provides for selecting a block size of pixels of the image, adding a masking signal to the image, determining a quantization error for at least one block in the image, and distributing the quantization error to neighboring blocks in the image to mask artifacts in the image. An output image is then encoded with a compression function. | 06-10-2010 |
20100333174 | METHOD AND APPARATUS FOR SOFTWARE DOWNLOADS IN A NETWORK - Files associated with the operation of gateway and client devices in a network may be downloaded with minimal operator intervention. Accordingly, a method includes receiving data including a first file, a first authentication element, and a second authentication element, the first authentication element being unique to a client device associated with the gateway device. The method also includes determining if the second authentication element is valid for the gateway device and storing the first authentication element and the second file for the client device if the second authentication element is valid for the gateway device. An apparatus includes a receiver that receives data, a processor that determines if the second authentication element is valid for the gateway device, and a memory that stores the first authentication element and a portion of the data for the client device if the second authentication element is valid for the gateway device. | 12-30-2010 |

20100333150 | METHODS AND APPARATUSES FOR PROVIDING LOAD BALANCED SIGNAL DISTRIBUTION - Methods and apparatuses provide load balanced signal distribution to client devices in a network, such as a digital home network. According to an exemplary embodiment, one of the methods includes the steps of receiving a request from a client device for downloading video from one of a plurality of video sources, receiving respective load indicators from first and second video receiving devices capable of receiving the plurality of video sources, selecting one of the first and second video receiving devices according to the load indicators, and instructing the selected video receiving device to transmit the video from the one of the plurality of video sources using an address known by the client device. | 12-30-2010 |
20130254425 | DNS FORWARDER FOR MULTI-CORE PLATFORMS - In a multi-core platform in which secondary processor cores do not have direct WAN connectivity, methods and apparatus are described that enable the secondary cores to provide DNS resolution services to their network applications or to attached client devices. In an exemplary embodiment, a primary processor core having direct WAN connectivity includes a DNS forwarder which shares with the platform's secondary processing cores DNS server IP address information acquired from a WAN-side DHCP server. Each secondary core implements a compatible DNS forwarder client to request DNS information from the primary core DNS forwarder, receive the information, and make it available to its operating system's DNS resolver module. Additionally, or alternatively, the primary core DNS forwarder may push updated DNS server information to each secondary core following a primary core DHCP client lease renewal. | 09-26-2013 |
20130262637 | DNS PROXY SERVICE FOR MULTI-CORE PLATFORMS - In a multi-core platform in which secondary processing cores do not have direct WAN connectivity, methods and apparatus are described that enable the secondary processing cores to provide DNS resolution services to their network applications and/or client devices attached thereto. In an exemplary embodiment, a primary processing core having direct WAN connectivity and a DHCP client includes a DNS proxy service module which acts as a DNS server to the platform's secondary processing cores. Each secondary processing core sends DNS queries to the primary core DNS proxy service module. A primary core DNS resolver regenerates DNS queries based on the DNS queries from the secondary cores and forwards them for resolution to WAN-side DNS servers whose IP addresses were provided to the DHCP client in response to an IP lease request. The resolved IP addresses are returned by the WAN-side DNS servers to the primary processing core, which provides them to the requesting secondary core applications or client devices, via the DNS proxy service module. | 10-03-2013 |
20140198802 | METHOD TO SELECTIVELY ADD PRIORITY TAGGING TO NETWORK TRAFFIC - A gateway device communicates with a client device on a local area network. The gateway device receives a dynamic host configuration protocol (DHCP) request from the client device; wherein the DHCP request includes information indicating whether, or not, the client device supports quality of service (QoS) treatment; and if the client device supports QoS treatment, the gateway device sends packets destined for the client device with QoS priority tagging information; and if the client device does not support QoS treatment, the gateway device sends packets destined for the client device without QoS priority tagging information. | 07-17-2014 |
20140376551 | METHOD AND APPARATUS FOR NULL VIRTUAL LOCAL AREA NETWORK IDENTIFICATION TRANSLATION - A method and apparatus are described including setting a default virtual local area network identification number of a switch to 0, receiving a data packet from a local area network interface, applying a virtual local area network header with identification number 0, if the data packet is untagged, determining if a virtual local area network identification number in a header of the data packet is a first predefined value, translating the virtual local area network identification number to a second predefined value in the header of the data packet if the virtual local area network identification number is equal to the first predefined value and forwarding the data packet to a local area network protocol stack network interface. | 12-25-2014 |

20080276485 | POWER DRYING SYSTEM - A system configured to dry containers before a date coding process includes a blower assembly, an air manifold and a bracket assembly. The blower assembly includes a centrifugal air blower. The air manifold is connected to the blower assembly and includes a plurality of air nozzles. The air nozzles are configured to be positioned over a conveyor line, wherein the air nozzles are configured to expel air moved by the centrifugal air blower. The bracket assembly is configured to adjustably mount the air manifold over the conveyor line, wherein the bracket assembly allows the air manifold to be horizontally and/or vertically adjusted with respect to the conveyor line. | 11-13-2008 |
20090235672 | TWO-STAGE COOLING SYSTEM - A two-stage cooling system configured to cool an interior of an enclosure includes a cabinet, a first vortex tube secured within the cabinet, and a second vortex tube secured within the cabinet. The cabinet defines a venting chamber. The first and second vortex tubes each include a hot pipe within the venting chamber and a cool gas delivery pipe extending outwardly from the cabinet. The first and second cool gas delivery pipes are configured to deliver cold gas to the interior of the enclosure. A separate thermostat may be operatively attached to each vortex tube and extend outwardly from the cabinet to be positioned within the interior of the enclosure. Additionally, first and second dampening sleeves may be secured around at least a portion of the first and second hot pipes, respectively, such that the dampening sleeves dampen noise produced by the vortex tubes. | 09-24-2009 |
