  • Patent number: 9258620
    Abstract: Aspects of a method and system for controlling data distribution via cellular communications with an integrated femtocell and set-top-box (IFSTB) device are provided. In this regard, a cellular enabled communication device may detect when it is within cellular communication range of a femtocell. Upon detection of the femtocell, the cellular enabled communication device may communicate instructions to a content source instructing the content source to deliver multimedia content to the femtocell. In instances that multimedia content is already being delivered to the cellular enabled communication device prior to the detection, the instructions from the cellular enabled communication device may instruct the content source to redirect the multimedia content to the femtocell. In this regard, the multimedia content may be delivered from the content source to the cellular enabled communication device via the femtocell.

  • Patent number: 9258059
    Abstract: Methods, systems, and computer program products are provided for inserting the packet into a tail of a linked list buffer, and the linked list buffer includes a plurality of Buffer Descriptors (BD), a HEAD pointer pointing to a null Buffer Descriptor (NullBD) and a NULLBD pointer. The NULLBD pointer is switched to point to the NullBD and the HEAD pointer to point to a valid BD which represents a memory address of payload data in the packet to be transmitted. Upon transmission of the packet, the HEAD pointer is converted to point to the NullBD and the NULLBD pointer to point to the valid BD. The valid BD pointed by the NULLBD pointer is finally transferred to a free linked list buffer so that the NULLBD pointer points to no memory address.

  • Patent number: 9258152
    Abstract: A receiver is optimized by adapting parameters of a linear equalizer component within the receiver. Data decisions and error decisions are generated. These data decision and error decisions are used to derive an error rate of data by measuring the number of margin hits that occur. A balance value is also calculated from the data decisions and the error decisions. The balance value is used to update parameters of the linear equalizer. The updating of the parameter continues until the number of margin hits has been minimized.

  • Patent number: 9258846
    Abstract: A system can provide quality-of-service based network resource allocation and utilization in a dynamic network environment. A system may determine a current quality level of current media data presented to a user by a remote system in communication with the first system. The system may determine if it can provide subsequent media data to the remote system at a higher quality level than the current quality level. As one example, the system may identify a network connection with the remote system that supports providing the subsequent media data at the higher quality level to the remote system. The system may then obtain the subsequent media data at the higher quality level and send the subsequent media data at the higher quality level to the remote system.

  • Patent number: 9256734
    Abstract: Embodiments of the present disclosure provide systems and methods for implementing a secure processing system having a first processor that is certified as a secure processor. The first processor only executes certified and/or secure code. An isolated second processor executes non-secure (e.g., non-certified) code within a sandbox. The boundaries of the sandbox are enforced (e.g., using a hardware boundary and/or encryption techniques) such that code executing within the sandbox cannot access secure elements of the secure processing system located outside the sandbox. The first processor manages the memory space and the applications that are permitted to run on the second processor.

  • Patent number: 9258225
    Abstract: A system and method for efficient matching regular expression patterns across multiple packets. A deep packet inspection system can be embodied in a switch ASIC using a flow tracker and a signature matching engine. The flow tracker can be positioned in an ingress portion of the switch ASIC at a location where packets in a bi-direction flow can be observed and recorded. The flow tracker generates a signature match request that is forwarded to a signature matching engine in an auxiliary pipeline. The signature matching engine is enabled to perform cross-packet signature matching using signature matching state machines and reports the signature matching results to the flow tracker using a response packet that is sent to the ingress pipeline.

  • Patent number: 9258055
    Abstract: A wireless microphone and wireless earpiece each may exchange radio frequency (RF) signals with a base unit and render content contained within the exchanged RF signals to a user. This wireless earpiece further includes a wireless interface, a processor, a speaker, a user interface, and an authentication module. The wireless interface allows the earpiece to wirelessly communicate with the base unit. The processor recovers communications exchanged with the base unit that the speaker then renders audible. A user interface coupled to the processor may alert the user to any additional incoming audio communications. Having received the alert, the user may select between the communications. The authentication module allows the wireless earpiece and microphone to pair and register with the base unit.

  • Patent number: 9258287
    Abstract: A secure active network includes a plurality of secure elements which communicate with one another to share and log information such as identification, location, and user activity associated with each secure element. Secure elements exchange data with one another, and log data received. The periodicity of communication between secure elements, encryption of the information, and the operating frequency in which the information is transmitted and received may be changed if communication is lost between any of the secure elements or if a determination is made that a secure element has traveled outside a predetermined zone. The integrity of the secure network may be verified at any time by comparing the logged information to a reference network.
