  • Publication number: 20230222799
    Abstract: Identifying activity in an area even during periods of poor visibility using a video camera and an audio sensor are disclosed. The video camera is used to identify visible events of interest and the audio sensor is used to capture audio occurring temporally with the identified visible events of interest. A sound profile is determined for each of the identified visible events of interest based on sounds captured by the audio sensor during the corresponding identified visible event of interest. Then, during a time of poor visibility, a subsequent sound event is identified in a subsequent audio stream captured by the audio sensor. One or more sound characteristics of the subsequent sound event are compared with the sound profiles associated with each of the identified visible events of interest, and if there is a match, one or more matching sound profiles are filtered out from the subsequent audio stream.

  • Patent number: 11191432
    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.

  • Patent number: 10572960
    Abstract: Methods, systems, and products measure health data related to a user. Often times a weight scale, blood pressure monitor, or other medical measurement device is shared among a group of users. A time-stamped physiological measurement is compared to a time-stamped message from a mobile device. If the timestamps are contemporaneous, then the physiological measurement is bound to the mobile device.

  • Patent number: 10244291
    Abstract: In an embodiment, a system and method permit a network subscriber to display on a channel of the network video data from a subscriber video database. The system may include, in addition to the network and the subscriber database, a server and a set top box. The set top box is configured to receive commands causing the set top box to retrieve video data from a network subscriber database, display the video data on a display unit; and to transmit the video data over the network to the server. The server is configured to transmit the video data from the server over the network such that the video data is displayable on a channel of the network.

  • Patent number: 10032118
    Abstract: A system that incorporates teachings of the present disclosure may operate, for example, obtaining a number of blogs including an initial set of annotated blogs and unannotated blogs. The initial set of annotated blogs are annotated as being either relevant to a selected media program or not relevant to the selected media program. A set of features is determined associating the selected media program with the unannotated blogs and a trained classifier is generated based on the set of features. The trained classifier is applied to the blogs to identify a subset of blogs relevant to the selected media program. An analysis is performed on the selected blogs to determine a trend related to the selected media program and a graphical user interface is presented that concurrently presents the selected blogs, the trend, and the selected media program. Other embodiments are disclosed.
