  • Patent number: 11916487
    Abstract: An asymmetric half-bridge converter is provided. The asymmetric half-bridge converter includes a switch circuit, a resonance tank, a current sensor, and a controller. The current sensor senses a waveform of a resonance current flowing through the resonance tank to generate a sensing result. The controller determines the sensing result. When the sensing result indicates that an ending current value of a primary resonance waveform of the resonance current is greater than a predetermined value, the controller performs a first switching operation on the switch circuit. When the sensing result indicates that the ending current value of the primary resonance waveform is less than or equal to the predetermined value, the controller performs a second switching operation on the switch circuit.

  • Patent number: 11916122
    Abstract: A method for forming a gate all around transistor includes forming a plurality of semiconductor nanosheets. The method includes forming a cladding inner spacer between a source region of the transistor and a gate region of the transistor. The method includes forming sheet inner spacers between the semiconductor nanosheets in a separate deposition process from the cladding inner spacer.

  • Publication number: 20110061144
    Abstract: The invention is related to a kind of foam mesh cap. The foam mesh cap has a foam layer that is composed of two pieces of cloth at outer sides and a piece of foam in the middle. Outside the foam layer there is an exterior fabric layer. The three parts are sewed together to form a pad. The two sides of the pad and multiple mesh sheets are sewed to form a cap body. The cap body is then sewed to a cap peak to make the foam mesh cap. As a result, the thick and firm pad can provide instant shape recovery and increase product durability by preventing water from getting into inner layer.

  • Publication number: 20100315996
    Abstract: A host apparatus, a transmission method and a tangible machine-readable medium storing a program of the transmission method for use in the host apparatus are provided. The host apparatus is for use in a wireless network which comprises a plurality of access points and a mobile node. The access points are wirelessly connected to the host apparatus. The host apparatus stores a statistics table relating to the mobile node. The host apparatus may be aware of the possible moving paths about the mobile node and proceed the data transmission with the mobile node via the access points in the possible moving paths, so as to save the resource of the wireless network.

  • Publication number: 20020091735
    Abstract: To facilitate location of establishment information, road map files are stored in a first memory, whereas establishment data for each of a plurality of establishments that are located in any of the road map files are stored in a second memory. The establishment data are classified geographically and include map location data that define a location of the corresponding establishment in any of the road map files. A third memory stores an establishment tag command for each of the establishments. A first processing unit receives a road map request from a user terminal. A second processing unit generates road map HTML that is provided to the user terminal so as that the latter can display a selected road map file according to the road map request and, if any one of the establishment data is encompassed by the selected road map file, so that the user terminal can display an index point at the location defined by the map location data of the encompassed establishment data.
