  • Publication number: 20240123222
    Abstract: A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.

  • Patent number: 11954919
    Abstract: Systems and methods are provided for developing/updating training datasets for traffic light detection/perception models. V2I-based information may indicate a particular traffic light state/state of transition. This information can be compared to a traffic light perception prediction. When the prediction is inconsistent with the V2I-based information, data regarding the condition(s)/traffic light(s)/etc. can be saved and uploaded to a training database to update/refine the training dataset(s) maintained therein. In this way, an existing traffic light perception model can be updated/improved and/or a better traffic light perception model can be developed.

  • Patent number: 11303682
    Abstract: A resource such as a server derives multiple streams of data based on particular content. Each of the multiple streams of data is encoded to enable play back of the content according to a different level of quality. The server transmits the multiple streams of data of differing levels of quality on a multicast link downstream to one or more intermediate nodes that, in turn, distribute the streams of data to end users. For example, an intermediate node retrieves a respective stream of data from the multiple streams of data and forwards the selected stream of data over a second portion of the multicast link to a respective client device. The intermediate node can transmit a different stream of data to the respective client device depending on available bandwidth. The client device plays back the transmitted stream of data to produce a rendition of the particular content.

  • Patent number: 10116994
    Abstract: Methods and apparatus for providing a supervisor such as a parent or guardian with a way to monitor and control the delivery of content, e.g., video and audio programs, to users of devices within a home. Exemplary embodiments include methods and apparatus for operating a home network monitoring device located in a home including detecting delivery of content to one or more users in the home, storing, in the home, portions of content delivered to a first user, presenting some of the stored portions of content to a person responsible for setting content restrictions applicable to the first user, and subjecting further content delivery to the first user via the home network to restrictions established by the person responsible for setting content restrictions applicable to the first user. Some embodiments also detect and report potential attacks, e.g., cyber attacks, on the home network.

  • Patent number: 9451337
    Abstract: Techniques disclosed herein include systems and methods for transmitting TV program related content to IP connected devices on a home network, or other local area network. Users can watch television while simultaneously receiving content related to TV programs currently being displayed on a television. TV centric and TV program related content can be transmitted to IP connected devices. Moreover, this TV program related content can be displayed at the same time as a television program is being displayed on a television. As such, the system can provide media synchronization within home network using the set-top box as a gateway for delivering the content. Users can watch TV at home, and at the same time receive TV program related content on a laptop, tablet computer, mobile phone, etc.

  • Patent number: 9210476
    Abstract: Methods and apparatus for supplying unbound applications with data via in-band program channel signaling are described. Unbound applications are STB or other customer premise device applications which continue to run when a tuner in the device changes between program channels. Applications executed in a STB, in accordance with the present invention, e.g., eBIF applications, continue to run despite changes in program channels with data being supplied via in-band signaling, out of band signaling, or a combination of in-band and out of band signaling. The methods and apparatus are well suited for supporting delivery of program catalog information relevant to an individual program channel using in-band signaling reducing or eliminating the need to delivery a multi-channel program catalog via out of band signaling to support various VOD applications.
