  • Publication number: 20170076736
    Abstract: A system for providing an acoustic environment recognizer for optimal speech processing is disclosed. In particular, the system may utilize metadata obtained from various acoustic environments to assist in suppressing ambient noise interfering with a desired audio signal. In order to do so, the system may receive an audio stream including an audio signal associated with a user and including ambient noise obtained from an acoustic environment of the user. The system may obtain first metadata associated with the ambient noise, and may determine if the first metadata corresponds to second metadata in a profile for the acoustic environment. If the first metadata corresponds to the second metadata, the system may select a processing scheme for suppressing the ambient noise from the audio stream, and process the audio stream using the processing scheme. Once the audio stream is processed, the system may provide the audio stream to a destination.

  • Publication number: 20170054813
    Abstract: An architecture that can employ a control plane for managing communications with respect to a set of sensors is provided. By utilizing a control plane, a distinction between control messages and data messages can be provided in a standardized way and the set of sensors can benefit from additional functionality and configurability. For example, the control plane can be employed to modify parameters associated with the set of sensors, which can be effectuated in real time and in situ as opposed to at the time of fabrication or deployment. Moreover, such modifications can relate to both the sensing portions of a particular sensor as well as the communication portions of a particular sensor.

  • Publication number: 20170019857
    Abstract: Energy consumption of cellular interfaces on multihomed mobile devices, such as smartphones, tablets and laptops can be improved by adjusting the inactivity timer of the cellular interface of the mobile devices based on the on/off status of non-cellular interface(s) on the mobile devices. Possible near-future data packets can be transmitted or received on the non-cellular interfaces that co-exist on the mobile devices and thus the inactivity timer of the cellular interface may be dynamically and more efficiently adjusted, based on the on/off status of non-cellular interface(s). If the non-cellular interface is available on the mobile device, then the inactivity timer can be set to be shorter than if only the cellular interface is available.

  • Patent number: 9544843
    Abstract: Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.

  • Patent number: 9521690
    Abstract: An arrangement and a method that, for a given pair of nodes that wish to intercommunicate with a high QoS measure, converts a portion of the contention-based network into a contention-less subnetwork by sending a reservation message and a confirmation message between the given pair of nodes. All nodes that are on the paths used for communicating between the pair of nodes are protected from interference by causing all nodes that potentially can interfere to enter a non-transmitting state.

  • Patent number: 9504051
    Abstract: Intra-cell upstream data forwarding can be utilized in a wireless network such as a wireless local area network. A network forwarding path can be determined based on the signal strength of an access point signal received at client stations within the network, referred to as the observed access point signal strength (OASS). In particular embodiments, a station that is either originating or forwarding a frame can insert its own OASS into the frame before transmitting it and a client station that receives a frame can forward it only if its own OASS exceeds the frame-enclosed OASS, by at least a predetermined amount.

  • Publication number: 20160324419
    Abstract: Devices, systems and methods are disclosed which relate to remotely monitoring the health of an individual. The individual wears a health monitoring device, with an attached strap, capable of sensing characteristics of the individual. These characteristics may include voice level and tone, movements, blood pressure, temperature, etc. The device allows individuals to constantly monitor their health without having to physically visit a doctor or other health care professional. Wireless communication, for instance with an Internet Protocol Television (IPTV) set-top box, allows measurements to be made and evaluated by a computerized healthcare service provider. For a more accurate evaluation, measurements are sent over the INTERNET to a service. The device communicates with services in order to diagnose the individual based upon the characteristics.
