  • Patent number: 11164327
    Abstract: Techniques are provided for estimation of human orientation and facial pose, in images that include depth information. A methodology embodying the techniques includes detecting a human in an image generated by a depth camera and estimating an orientation category associated with the detected human. The estimation is based on application of a random forest classifier, with leaf node template matching, to the image. The orientation category defines a range of angular offsets relative to an angle corresponding to the human facing the depth camera. The method also includes performing a three dimensional (3D) facial pose estimation of the detected human, based on detected facial landmarks, in response to a determination that the estimated orientation category includes the angle corresponding to the human facing the depth camera.

  • Patent number: 11039009
    Abstract: A system and method for facilitating real-time communication with a caller without a user accepting a call, wherein the system or method: receives a notification of the call; obtains information about the user and the caller from one or more data sources; determines the user's temporal status at a given point in time and the caller's identity based on the information; generates a context-specific message based on the user's temporal status and the caller's identity, wherein the message summarizes the user's temporal status; and provides the message to the caller. Alternatively, the message is a generic message, when the caller's identity cannot be determined.

  • Patent number: 10986713
    Abstract: A retrofit lamp is to be used with a ballast. A shunt switch is provided in parallel with an output load and is adapted to shunt input terminals of the lamp using pulse width control so as to tune the current through the lighting element. This current control is used to enable compatibility with different ballasts and to provide dimming control. A detection circuit is used to detect an abnormal drive condition of the retrofit lamp and the pulse width control of the shunt switch can then be overridden by holding the shunt switch at a stable state for a certain duration. This prevents overload conditions and avoids DC signals in the event of component failures.

  • Patent number: 10915472
    Abstract: A computer system with programmable serial presence detection (SPD) data is disclosed. The computer system uses a user-programmable memory to store virtual SPD data which includes the configuration information of the memory module. The virtual SPD data is stored separately from the system boot code of the computer system. A computing unit uses a memory driver to drive the memory module. The memory driver accesses the user-programmable memory through a virtual SPD module to acquire the configuration information of the memory module.

  • Patent number: 10740912
    Abstract: Techniques are provided for detection of humans in images that include depth information. A methodology embodying the techniques includes segmenting an image into multiple windows and estimating the distance to a subject in each window based on depth pixel values in that window, and filtering to reject windows with sizes that are outside of a desired window size range. The desired window size range is based on the estimated subject distance and the focal length of the depth camera that produced the image. The method further includes generating classifier features for each remaining windows (post-filtering) for use by a cascade classifier. The cascade classifier creates candidate windows for further consideration based on a preliminary detection of a human in any of the remaining windows. The method further includes merging neighboring candidate windows and executing a linear classifier on the merged candidate windows to verify the detection of a human.

  • Publication number: 20200151255
    Abstract: Providing cognitive responses with an electronic message system includes predicting an urgency level corresponding to an electronic message received by the system based on detecting pre-defined features within the message and assigning a classification to the message based on the detected features. The message and corresponding urgency level can be mapped to a response action based on the classification assigned to the message. A notification of the response action and corresponding urgency level can be generated.
