  • Publication number: 20230239663
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, a processing system that analyses, without user intervention, content of a first message directed from equipment of a sending user to equipment of a receiving user, to identify a task. The processing system determines that the receiving user is unable to perform the task according to biometric data of the receiving user. The biometric data is selected from one of heart rate, blood pressure, respiratory rate, and combinations thereof. According to the content of the first message and the biometric data obtained from the receiving user, the processing system determines that the task should be delegated to another user, and responsive thereto, provides a second message associated with the task to equipment of the other user. Other embodiments are disclosed.

  • Patent number: 11658843
    Abstract: Full-duplex communications are provided by modifying the Media Access Control sub-layer of communication node protocols. The modification allows communication nodes to communicate with one another in full-duplex, where each node transmits and receives data simultaneously with other nodes in a single frequency. A timing of the simultaneous data transmissions, acknowledgments, and short-interframe-space waiting periods can be determined based on network-allocation-vector data transmitted in association with request-to-send or clear-to-send signals.

  • Publication number: 20210273772
    Abstract: Disclosed herein are a systems and method for using frequency tones to schedule full-duplex communications between at least two full-duplex communication nodes. Communication nodes having data to transmit send, as part of two contention rounds, two separate and randomly selected frequency tones. In the first contention round, all nodes having data to transmit simultaneously transmit a frequency tone. Based on these first frequency tones, groups of nodes are formed. Each group of nodes in turn transmits a second set of frequency tones, and a schedule of full-duplex communications is created based on the second frequency tones.

  • Patent number: 10979205
    Abstract: Disclosed herein are systems, methods, and computer-readable storage devices for reducing inter-cellsite interference during full-duplex communication. A system receives a channel amplitude and a phase estimate between a first station and a second station, the first station and the second station creating inter-cellsite interference on a channel during full-duplex communications. The system calculates a level of the inter-cellsite interference between the first station and the second station based on the channel amplitude and the phase estimate and generates a cancellation signal based on the inter-cellsite interference. The system then communicates the cancellation signal to the first station for transmission with additional data during additional full-duplex communications.

  • Patent number: 10965490
    Abstract: A method includes dividing, at a cable modem termination system, a transmit stream into multiple data streams. The multiple data streams include a first data stream and a second data stream. Each of the multiple data streams has a lower bit rate than a bit rate of the transmit stream. The method includes transmitting, via the cable modem termination system, the first data stream over at least a first channel of a group of channels. The method also includes transmitting, via the cable modem termination system, the second data stream over at least a second channel of the group of channels. The group of channels supports traffic to a plurality of destinations. The first channel and the second channel are frequency-division multiplexed channels.

  • Patent number: 10966064
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, a processor that can maintain a first virtual task list associated with one of a sending user or a receiving user. A first message originating at equipment of the sending user is received and content of the first message is analyzed to determine a task. Behavior information is obtained associated with one of the sending user, the receiving user or both, and first virtual task list is adjusted to obtain a modified virtual task list according to the content of the first message and the behavior information. A second message is provided to one of the receiving user or another user according to the modified virtual task list. Other embodiments are disclosed.

  • Patent number: 10924256
    Abstract: Disclosed herein are systems, methods, and computer-readable storage media for enabling improved cancellation of self-interference in full-duplex communications, or the transmitting and receiving of communications in a single frequency band without requiring time, frequency, or code divisions. The system estimates the signal strength and phase of a self-interference signal, generates a cancellation signal based on this estimate, then uses the cancellation signal to suppress the self-interference before sampling received analog signal. After applying the cancellation signal, the system samples and digitizes the remaining analog signal. The digitized signal is then subjected to additional digital cancellation, allowing for extraction of the desired signal.

  • Patent number: 10779248
    Abstract: Incorporation of a mesh base station in a wireless network is presented herein. The mesh base station can utilize common wireless resource allocations as a corresponding wireless base station while transmitting to wireless subscriber stations during the same time period. The mesh base station obtains a data packet from the wireless base station over a backhaul link during a scheduled time period and transmits the data packet to the designated wireless subscriber station during another scheduled time period. The wireless base station and the mesh base station can also receive data packets from wireless subscriber stations during a same time period. A wireless network can be configured with two mesh base stations at an approximate boundary of two adjacent sector coverage areas, where a coverage area is supported by a wireless base station and each mesh base station supports wireless subscriber stations within a coverage radius.

  • Publication number: 20200143012
    Abstract: A method for digital rights management includes a digital agent for contacting a media host. Media content is compared to a user profile and an identification confidence level is assigned to the media based on the comparison. A digital agent contacts a host of the media based on the identification confidence level, the type of media, and the context of the media. The digital agent requests one or more actions of a media host based on user designations concerning information related to the media. The identification confidence level is generated based on a plurality of user characteristic confidence levels which are generated based on media being analyzed.

  • Patent number: 10592658
    Abstract: A password recovery technique for access to a system includes receiving a request from a first party to recover the first party's password to access the system, receiving a selection of a second party from the first party, sending a message to the second party requesting that the second party authorize the request to recover the first party's password, receiving authorization from the second party for the request to recover the first party's password, and resetting the first party's password responsive to receiving authorization from the second party.
