  • Patent number: 11361885
    Abstract: A method includes coating at least one conductive element of an electronic device with an electrically non-conductive thixotropic liquid. An electronic device includes a first layer including an upper conductive element, a second layer including a lower conductive element, and a spacer positioned between the layers. The first layer, the second layer, and the spacer define a sensing chamber in which the upper and lower conductive elements move to vary the resistance of the electronic device. A non-conductive thixotropic liquid is present within the sensing chamber. Movement of the layers toward each other displaces the thixotropic liquid from an initial state coating at least one of the conductive elements to permit contact between the conductive elements, and movement of the first layer and the second layer away from each other returns the thixotropic liquid to the initial state.

  • Publication number: 20060015799
    Abstract: This invention provides an efficient method of error tracking which quickly recovers the error packet of data. A side information is sent along with a normal video stream that can be used by an intermediate network node in order to improve the quality of the video transmission. The intermediate node receives the original video stream as well as the side information and uses the side information to reduce the error propagation. The error tracking is signaled from the intermediate node to the mobile phone device and the intermediate network node functions the error correction. The side information can then be used to refresh or update those areas that are affected by error concealment and error propagation.
