  • Publication number: 20100018982
    Abstract: A heating and cooling cup includes a cup body, a stirring device, a heating and cooling chip, and a heat sink module. A heat conductive block is disposed under the cup body, the heat conductive block abuts against the heating and cooling chip, the stirring device has a stirring rod disposed in the cup body, and a bottom surface of the heating and cooling chip abuts against a heat conductive block of the heat sink module. A temperature of the cup body is changed through the heating and cooling chip, for cooling or heating liquid food in the cup body, and the liquid food is forced to generate convection through the stirring rod for accelerating a temperature variation process.

  • Publication number: 20100006131
    Abstract: An automatic folding tent includes at least a plurality of main brackets, auxiliary brackets, connecting rod groups, elevation devices, and a tent cloth. After the main brackets and the auxiliary brackets are pivoted, the connecting rod groups for supporting the auxiliary brackets to unfold are disposed between the main brackets and the auxiliary brackets. The auxiliary brackets are gathered at a top block, the elevation device is disposed on a top end of the main bracket and is power-connected to the connecting rod group, and the tent cloth is wrapped on top of the main brackets and the auxiliary brackets. Accordingly, the elevation devices are controlled to synchronously operate through a remote controller, so as to actuate the main brackets to ascend and descend, and to actuate the auxiliary brackets to unfold or fold, thereby automatically operating the tent to fold and unfold.

  • Publication number: 20080141359
    Abstract: A method for preventing unauthorized connection in a network system mainly includes adding an authentication key in the LLDP (link layer discovery protocol) transmitted in accordance with the 802.1ab communication protocol so as to proceed with security mechanism under the structure of 802.1ab communication protocol. The method for preventing unauthorized connection includes receiving a LLDP packet satisfying the 802.1ab communication protocol transmitted from a second network device by a first network device in a network system; analyzing the LLDP packet and checking whether the LLDP packet contains a legitimate authentication key; and if the authentication key does not exist or is illegitimate, then block all packets transmitted from the second network device so as to prevent the unauthorized second network device from using the network transmission service provided by the first network device.

  • Publication number: 20080130517
    Abstract: A method and apparatus for intelligent automatic reconfiguration of a network system basically implements an automatic reconfiguration apparatus to acquire the configuration of every network device and generates a topology of the network devices. Afterward, the automatic reconfiguration apparatus can detect the status of the network devices. When some network device is replaced by a new network device due to a breakdown or other factors, the automatic reconfiguration apparatus can detect the changed status and check the hardware version as well as the corresponding location in the topology of the former network device. If the e hardware version of the new network device is identical to the hardware version of the corresponding former network device in the topology, the disclosed apparatus can automatically load the stored prime configuration into the new network device for performing automatic configuration to the network device.

  • Publication number: 20080130573
    Abstract: A method for automatically allocating channels of a wireless network system comprises the steps of: actuating one of access points (APs) for collecting channel status information, such as channel numerals and Received Signal Strength Incident (RSSI), of the other of the access points near by that access point; calculating an accumulated RSSI value of each of the access points according to the collected channel numerals and the RSSI value via a Network Management Server (NMS); calculating the accumulated RSSI value of each of the access points by weighting to obtain a weighted RSSI value thereof; and switching an operation channel of the actuated access point into the better channel having a relatively lower weighted RSSI value for improving the overall efficiency of the wireless network system.

  • Publication number: 20080123529
    Abstract: A method for providing load balance to a wireless network system is disclosed, wherein a network management server (NMS) is used to group a plurality of access points into a plurality of groups. Each of the access points is pre-set with a plurality of water level values corresponding to an acceptable load thereof, and each of the water level values is pre-set with a corresponding trap up value. Only when the real-time load of one of the access points is up to the trap up value thereof, the access point actively sends a signal of a corresponding load status thereof to the NMS. Meanwhile, the NMS checks the water level values of the other access points belonged to the same group of the access point.
