  • Publication number: 20180130138
    Abstract: Systems, methods, and software described herein enhance the management of users and groups within a social media context. In one implementation, a user may request a generation of a new user group in a social media service. In response to the request, the social media service may receive attributes that the user desires to share with other members of the group. Once received, the social media service may identify one or more other users that share the attributes with the user, receive a message from the user to confirm the generation of the new user group, and provide the message to the one or more other users that share the attributes with the user.

  • Patent number: 9965865
    Abstract: Devices and techniques are generally described for segmentation of image data using depth data. In various examples, color image data may be received from a digital camera. In some examples, depth image data may be received from a depth sensor. In various examples, the depth image data may be separated into a plurality of clusters of depth image data, wherein each cluster is associated with a respective range of depth values. In some further examples, a determination may be made that a first cluster of image data corresponds to an object of interest, such as a human subject, in the image data. In various examples, pixels of the first cluster may be encoded with foreground indicator data. In some further examples, segmented image data may be generated. The segmented image data may comprise pixels encoded with the foreground indicator data.

  • Patent number: 9961012
    Abstract: The customization of a communication pipelines having multiple stages. For each stage, a set of agent(s) is/are identified as available for adding to that stage. Furthermore, any stages that already have an agent assigned are identified. In response to receiving a user selection of an agent to be assigned to a particular stage, that does not already have an agent assigned, the selected agent is assigned to the stage. An enforcement agent enforces that there be only one agent assigned at most to each stage. Assignments of agents are made per stage. This allows the functionality of the agent to be simplified more towards augmenting the functionality of the stage. Accordingly, the logic of the agent is simplified, thereby making it more likely that there will be a healthy quality of agents available to select from for each stage.

  • Publication number: 20180115815
    Abstract: Disclosed is a signal processor for headphone off-ear detection. The signal processor includes an audio output to transmit an audio signal toward a headphone speaker in a headphone cup. The signal processor also includes a feedback (FB) microphone input to receive a FB signal from a FB microphone in the headphone cup. The signal processor also includes an off-ear detection (OED) signal processor to determine an audio frequency response of the FB signal over an OED frame as a received frequency response. The OED processor also determines an audio frequency response of the audio signal times an off-ear transfer function between the headphone speaker and the FB microphone as an ideal off-ear response. A difference metric si generated comparing the received frequency response to the ideal off-ear frequency response. The difference metric is employed to detect when the headphone cup is disengaged from an ear.

  • Patent number: 9935779
    Abstract: In some embodiments, a switch module is configured to receive from a first edge device a multicast data unit having a VLAN identifier. The switch module is configured to select a set of port modules based on the VLAN identifier. The switch module is configured to define an unmodified instance of the multicast data unit for each port module from the set of port modules. The switch module is configured to send the unmodified instance of the multicast data unit to each port module from the set of port modules, such that each port module applies a filter to the received instance of the multicast data unit to restrict that received instance of the multicast data unit from being sent to a second edge device via that port module if the second edge device is associated with a VLAN domain different than a VLAN domain of the first edge device.
