Various techniques are provided to efficiently detect the position and angular velocity of an object relative to a compact radar system including a transmitter antenna array and a receiver antenna array. In one example, a method includes repeatedly scanning a transmitter antenna array and a receiver antenna array of an object sensing system through a plurality of designated transmitter and receiver channels over a period of time to generate a time series of measured channel responses corresponding to each one of the designated channels, determining a time series of directional vectors to or from an object scanned by at least one of the designated channels, and/or a corresponding time series of average phase differences, based, at least in part, on the time series of measured channel responses, and determining an angular velocity of the object from the time series of directional vectors and/or the corresponding time series of average phase differences.

Disclosed wireless tunneling system includes two wireless tunneling apparatuses that communicate with each other through the wireless link. A local wireless tunneling apparatus is coupled to a local processing apparatus through a wired connection and a remote wireless tunneling apparatus is coupled to the remote processing apparatus through another wired connection. The two processing apparatuses bi-directionally communicate with each other through the wireless link using the two wireless tunneling apparatuses as if the two processing apparatuses were connected through a wired connection.

Aspects relate to correcting Inphase/Quadrature (I/Q) imbalances across multiple wireless elements such as multiple receive elements or multiple transmit elements. In one example implementation, I/Q imbalances can be corrected using a digital circuit provided within a digital portion of a direct conversion wireless element (upconversion or downconversion) that implements only two multiplications and one addition per pair of I and Q samples.

A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a structured application layer message and identifies, in message classification requirements at the network device, a reference to a classification portion of the structured application layer message and an operation portion of the structured application layer message. The system extracts, based on one or more expressions, a portion of the message for classifying the structured application layer message and classifies the message using the extracted portion and according to the message classification requirements. At least in part by accessing information indicated by one or more location identifiers, at least one operation is performed on the classified structured application layer message.

An application framework may include a cloud-independent application manager, a cloud-independent content services manager, and cloud-independent content services servers. The framework may dynamically install and manage scalable, multi-tenant applications in a cloud, and may scale the applications, as needed. The application manager may receive and handle requests to install application domains and configurations thereof, and may receive and respond to requests for information about servers on which installed methods are available. The content services servers may execute installed methods, using underlying resources of the cloud, through a cloud-specific SPI. The content services manager and application manager may work together using shared cloud storage to provide scalable content services at a very large scale. In the context of the framework described herein, an 'application' may be defined by methods bundled into configurations, and by various cost-based and/or performance-based rules that specify how server instances providing those methods are to be managed.

A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

A method is disclosed for performing message payload processing functions in a network element on behalf of an application. According to one aspect, a network element intercepts data packets comprising network layer or transport layer headers having an address of a destination which destination differs from the network element. The network element determines whether information contained in layer 2-4 headers of the data packet satisfies specified criteria. If the information satisfies the specified criteria, the network element directs the data packets to a blade of the network element that performs processing based on an application layer message at least partially contained in the data packets. If the information does not satisfy the specified criteria, the network element forwards the data packets towards the destination without sending them to the blade.

A method is disclosed by which network elements such as packet routers and packet switches guarantee the delivery of application layer messages within a network. According to one aspect, a first network element retrieves an application layer message from a source message queue, adds a message identifier to the application layer message, encapsulates the application layer message into data packets, and sends the data packets toward a destination application. A second network element intercepts the data packets, determines the application layer message from payload portions of the data packets, determines the message identifier from the application layer message, stores the application layer message in a destination message queue, generates an acknowledgement message that contains the message identifier, and sends the acknowledgement message toward a source application. The first network element intercepts the acknowledgement message and concludes that the application layer message within the matching message identifier was successfully delivered.
