  • Publication number: 20190381324
    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.

  • Publication number: 20190214700
    Abstract: A power divider/combiner circuit with coupled inductors is provided. With coupled inductors, the new circuit topology exhibits broader bandwidth for insertion loss, port matching and isolation compared with traditional power divider/combiner circuit topologies. The coupled inductors can be implemented for single-stage low-pass networks, multi-stage low-pass networks, or multi-stage wide-band networks. For example, the power divider/combiner circuit includes a first coupled inductor circuit coupled to an input terminal that provides a first signal path to a first output terminal, and a second coupled inductor circuit coupled to the input terminal that provides a second signal path to a second output terminal. Each of the coupled inductor circuits include multiple inductors that are tightly and positively magnetically coupled to one another.

  • Patent number: 10128947
    Abstract: This application discloses a method for an optical drive chip to control a light-emitting device and an optical drive chip thereof. A receiving unit of the optical drive chip obtains to-be-sent data, and transmits the to-be-sent data to an execution unit of the optical drive chip; and the execution unit converts the to-be-sent data into a drive signal according to a control parameter set, where the drive signal is used to control a light-emitting device to emit visible light. Because the optical drive chip converts the to-be-sent data into the drive signal according to the control parameter set so as to control the light-emitting device, rather than obtaining a single control parameter one by one to control the light-emitting device, no delay problem occurs in a process of controlling the light-emitting device by the optical drive chip. In addition, the to-be-sent data is encoded, which ensures data transmission reliability.

  • Patent number: 9930575
    Abstract: A scalable medium access control (“MAC”) module is provided that avoids conflict resource reservation so that network performance does not degrade as the number of hops or nodes in a wireless network increases. The MAC also provides different access schemes for traffic with different quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized. Furthermore, the resource allocation scheme determines the routing path as resources is allocated for data traffic, thereby achieving more robust layer-2 routing at the MAC layer. Finally, the scalable MAC is compliant with both WiMedia MAC and IEEE 802.15.3 MAC.
