  • Publication number: 20240114458
    Abstract: The present invention provides a wireless communication method, wherein the wireless communication method includes the steps of: controlling the electronic device to operate in an active mode and communicating with an access point; after a traffic between the electronic device and the access point ends, controlling the electronic device to operate in a first mode, and transmitting a null frame to notify the access point that the electronic device enters a power saving mode; and during the first mode, controlling the electronic device to leave the power saving mode and transmitting at least one query signal to the access point to ask data.

  • Patent number: 11929418
    Abstract: A gate structure includes a substrate divided into an N-type transistor region and a P-type transistor region. An interlayer dielectric covers the substrate. A first trench is embedded in the interlayer dielectric within the N-type transistor region. A first gate electrode having a bullet-shaped profile is disposed in the first trench. A gate dielectric contacts the first trench. An N-type work function layer is disposed between the gate dielectric layer and the first gate electrode. A second trench is embedded in the interlayer dielectric within the P-type transistor region. A second gate electrode having a first mushroom-shaped profile is disposed in the second trench. The gate dielectric layer contacts the second trench. The N-type work function layer is disposed between the gate dielectric layer and the second gate electrode. A first P-type work function layer is disposed between the gate dielectric layer and the N-type work function layer.

  • Publication number: 20240080117
    Abstract: The present invention provides a wireless communication method of an electronic device, wherein the electronic device includes a first radio and a second radio, a maximum bandwidth or a maximum. NSS supported by the first radio is different from a maximum bandwidth or a maximum NSS supported by the second radio. The wireless communication method includes the step of: using the first radio to communicate with another electronic device; determining if parameters of the electronic device satisfy a condition; and in response to the parameters of the electronic device satisfying the condition, enabling the second radio and using the second radio to communicate with the another electronic device, and disabling the first radio.

  • Publication number: 20210206662
    Abstract: A water sterilizing tube includes a shell, an outer tube, an inner tube and a UV lighting module. The shell has a first end, a second end and an annular wall. The first end is provided with a water inlet and a water outlet. The outer tube is coaxially disposed in the shell. An end of the outer tube communicates with the water outlet. An air gap is formed between the outer tube and the annular wall. The inner tube is coaxially disposed in the outer tube. An end of the inner tube communicates with the water inlet. An extended channel is formed between the outer and inner tubes. The UV lighting module has a UV light corresponding to the outer tube. An axis line of the outer and the inner tube and a direction of light emitting of the UV light are superposed with each other.
