Abstract:

Disclosed is a media access controller for transferring data along a computer network. The media access controller includes a transmit media access controller that is configured to process out-going packet data received from an upper layer for transmission to a lower layer. A receive media access controller that is configured to process in-coming packet data received from the lower layer for transmission to the upper layer. A transmit multi-packet queue FIFO for receiving the out-going packet data from the upper layer before being passed to the transmit media access controller. A receive multi-packet queue FIFO for receiving the in-coming packet data that is received by the receive media access controller. The media access controller further including a media access controller manager interfacing with the transmit and receive media access controllers. The media access controller manager being responsible for managing the flow of packet data through the transmit and receive multi-packet queue FIFOs.

International Classification:

B01D 59/44
H01J 49/00

US Classification:

250282, 250281

Abstract:

Relative quantitative information about components of chemical or biological samples can be obtained from mass spectra by normalizing the spectra to yield peak intensity values that accurately reflect concentrations of the responsible species. A normalization factor is computed from peak intensities of those inherent components whose concentration remains constant across a series of samples. Relative concentrations of a component occurring in different samples can be estimated from the normalized peak intensities. Unlike conventional methods, internal standards or additional reagents are not required. The methods are particularly useful for differential phenotyping in proteomics and metabolomics research, in which molecules varying in concentration across samples are identified. These identified species may serve as biological markers for disease or response to therapy.

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709223, 709229

Abstract:

A system for providing single view of content in a network of devices includes a communication module that detects devices connected to the network, a directory module that discovers content in each detected device via the communication module and maintains a directory of such available content providing a single view of the discovered content for access thereto, and a content manager that provides access to the single view.

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709223, 709202, 709227

Abstract:

A system and method for managing a group of networked, heterogeneous devices, wherein the group of devices are regarded as a logically single “device”. This method separates the state management aspect from control aspect, such that applications using this method need not manage the devices and data directly, and as a result can interact with a simplified, single ‘device’, or focus on controlling the simplified, single ‘device.

Assignee:

Samsung Electronics Co., Ltd. - Suwon

International Classification:

G06F 15/16

US Classification:

709249, 709227

Abstract:

A method of aggregating control in a first network and a second network, the first network having first devices and the second network having second devices. A communication channel is established between the first and second networks; from the first network the second devices in the second network are discovered through the communication channel; and from the first network one of the second devices in the second network is controlled through the communication channel. The first and second network can be connected but isolated. Further, the first and second networks can implement different network protocols, or the same network protocol.

International Classification:

G06F 15/173
G06F 15/16

US Classification:

709246000, 709223000

Abstract:

A synchronization controller in a network of devices, provides content synchronization between the available content in the network and the content on another device. When the synchronization controller identifies the device for content synchronization with the home network, the synchronization controller attempts to match the device's content with content available in the home network. When there is a mismatch, the content manager starts a content session to transfer content from the device to the home network, or vice versa. During this process, the device need not know which home device it synchronized to, nor does it need to know what kind of format the content is stored in.

International Classification:

H04L 12/28

US Classification:

370392000, 370401000

Abstract:

A method of maintaining persistent unique identifiers for devices interconnected in a network. Information is obtained from a device and a fingerprint generated from that information. It is then determined if the fingerprint is previously associated with an identifier in the network. If the fingerprint is not previously associated with an identifier in the network, then a new identifier associated with the fingerprint is generated, and the fingerprint and the associated new identifier is stored in a memory, wherein the new identifier forms a persistent unique identifier (PUID) for that device. Otherwise, if the fingerprint is not previously associated with an identifier in the network, then the associated identifier stored in the memory is used as the persistent unique identifier (PUID) for that device.

International Classification:

H04L 9/00

US Classification:

713182000

Abstract:

An authentication method and system is provided for asynchronous eventing between a client and a server over the Internet. In a subscription phase, the client sends a subscription request to the server to express interest in receiving notifications associated with one or more particular events that may asynchronously occur on the server. The client authenticates the server by checking the identity of the server, and if the client determines that the server can be trusted, the client subscribes the notifications, otherwise, the client does not subscribe. After a successful subscription, in a notification phase, the server notifies each client that has subscribed for a particular type of event. Each client upon receiving a notification, authenticates the server by verifying that the received notification is sent by the server with which the client subscribed for the notification.
