  • Patent number: 11032237
    Abstract: A communication device of a first wireless network determines that a first value of a first basic service set (BSS) color identifier is the same as a value of a second BSS color identifier corresponding to a neighboring second wireless network. In response, the communication device determines a second value of the first BSS color identifier. The communication device transmits one or more packets that each include i) an indication that the first BSS color identifier is changing, ii) the second value of the first BSS color identifier, and iii) a respective integer number of remaining beacon intervals corresponding to a start time when the second value of the first BSS color identifier will supersede the first value of the first BSS color identifier. Based on the start time, the communication device begins to use the second value of the first BSS color identifier with communications in the first wireless network.

  • Patent number: 11029774
    Abstract: The present disclosure relates to a touch panel and a touch screen. In the touch panel, the cathode is reused. In the touch control stage, each of the cathodes serves as a touch electrode, and normal display and touch functions of the touch panel can be realized by a time-division driving manner. Specifically, in the display stage, the pixel circuit controls the light emitting state of each pixel point (each pixel point has a light emitting device including a cathode); in the touch control stage, touch control signals are applied onto all control signal terminals of the pixel circuit and the cathodes at the same time. By doing so, on the basis that the touch control function can be realized, the synchronous driving of the touch control electrodes and the electrodes corresponding to the touch control electrodes can be realized.

  • Patent number: 11027140
    Abstract: The invention provides an implantable vagal nerve stimulator having a “passive” generating power source that harvests the stomach's movements to transform kinetic energy to electrical charge without the need for a battery. In this regard, the invention is self-powering and is automatically timed to stomach peristalsis. While sporadic stimulation to the vagal nerve would seem too infrequent to cause weight loss effects, electrical stimulation delivered at the optimal time (e.g., during food consumption) has been found to optimize the effects of vagal nerve stimulation, giving the user's brain a “full stomach” signal before the user over-consumes food.
