  • Publication number: 20170154066
    Abstract: An approach to enable subscription to a remote content repository without a native subscription service based on a change monitor deployed near the remote content repository. The change monitor takes advantage of a change log associated with the content repository to determine when changes to the repository occur and compares the changes from the change log to a subscription list provided from a subscription datastore. When changes in the repository match the subscription list then the change monitor sends a change notice toward the subscriber. The change monitor manages the subscription list based on polling the subscription datastore and replies to change notices indicating notices for subscribed objects are no longer necessary.

  • Patent number: 9171197
    Abstract: A facial tracking method for detecting and tracking at least one face image in a region during a time period. The facial tracking method includes a step of performing an image acquiring operation, a step of performing a facial detecting operation to detect whether there is any face image in the entire of a current photo image, and at least one step of performing a facial tracking operation. For performing the facial tracking operation, plural tracking frames are located around a face image of the current photo image, and a similarity between the face image of the current photo image and the image included in each tracking frame in order to judge whether the face image exists in the next photo image. By the facial tracking method of the present invention, the time period of tracking face images is largely reduced.

  • Publication number: 20110158546
    Abstract: A system and a method are provided for generating a control instruction by using an image pickup device to recognize a user's posture. An electronic device is controlled according to different composite postures. Each composite posture is a combination of the hand posture, the head posture and the facial expression change of the user. Each composite posture indicates a corresponding control instruction. Since the composite posture is more complex than peoples' habitual actions, the possibility of causing erroneous control instruction from unintentional habitual actions of the user will be minimized or eliminated.

  • Patent number: 7744250
    Abstract: An LED lamp includes a heat sink (10), a plurality of heat pipes (20) mounted on outer sidewalls (120) of the heat sink, and a plurality of LED modules (30) attached on the outer sidewalls of the heat sink with a portion of each LED module contacting a corresponding heat pipe directly. A plurality of fins (14) extend inwardly from an inner wall of the heat sink in a manner such that a through hole (16) is enclosed by the fins, thereby providing an airflow passage axially through the heat sink. By the use of the heat pipes, heat generated by the LED modules can be transferred to the heat sink evenly, whereby the heat can be dispersed to ambient air efficiently and rapidly.
