  • Patent number: 11264699
    Abstract: An antenna structure includes a metal mechanism element, a ground element, a first radiation element, a second radiation element, and a dielectric substrate. The metal mechanism element has a slot. A notch is formed on an edge of the metal mechanism element. The notch and the slot are connected to each other. The ground element is coupled to the metal mechanism element. The first radiation element has a feeding point. The second radiation element is coupled to the first radiation element and includes a first extension portion. The second radiation element extends across the slot. The first extension portion is parallel to the slot. A vertical projection of the first extension portion at least partially overlaps the slot. The dielectric substrate is adjacent to the metal mechanism element. The first radiation element and the second radiation element are disposed on the dielectric substrate.

  • Patent number: 10819632
    Abstract: A router including a communication device, a first controller, a storage device, and a second controller is provided. The communication device receives a plurality of first packets of a connection and at least one second packet of the connection subsequent to the first packets. The first controller analyzes the first packets to determine a plurality of transport-layer parameters associated with the connection. The storage device stores the transport-layer parameters. The second controller performs traffic management on the second packet according to at least part of the transport-layer parameters stored in the storage device.

  • Patent number: 7056105
    Abstract: A unit utilizing current to control reciprocation for pushing fluids, including a chamber, a magnet, a coil connected with a circuit, a first inlet, a first outlet, a second inlet, a second outlet, a first valve and a second valve. The magnet is slidably disposed in the chamber. The coil is disposed around the chamber for driving the magnet to reciprocally move. The first inlet and first outlet are disposed at one end of the chamber. The second inlet and second outlet are disposed at the other end of the chamber. The first valve is disposed between the first inlet, the first outlet and the chamber. The second valve is disposed between the second inlet, the second outlet and the chamber. The magnet can drive the first and second valves to suck a fluid into the first and second inlets and push a fluid out of the first and second outlets.
