Abstract:
A fan assembly and impeller thereof. The fan assembly includes a plurality of blades and a hub. The hub includes an upper surface and a center point. The blades have bottom portions arranged in a circle on the upper surface with respect to the center point.
Abstract:
A composite heat-dissipating device is provided for significantly increasing the number and size of blades so as to enhance the heat-dissipating performance. The composite heat-dissipating device is constructed by a plurality of impellers, each of which includes a plurality of blades. When the plurality of impellers are assembled together, the plurality of blades are arranged around the hub of the composite heat-dissipating device and there is an overlapped region formed between every two adjacent blades.
Abstract:
A heat-dissipating module includes a heat sink and a fan device. The fan device may be disposed on the heat sink, or inserted into the heat sink to reduce the height. The fan device includes a first rotor blade and a second rotor blade. The first rotor blade and the second rotor blade are connected in series. The rotation speed of the first rotor blade is controlled by a first control circuit, and the second rotor blade is controlled by the second circuit. Thus, the second control circuit increases the rotation speed of the second rotor blades when the first rotor blades is failed.
Abstract:
A substrate cleaning apparatus includes a chamber having a substrate support capable of supporting and rotating a substrate in the chamber. A cleaning solution injector is provided to inject a cleaning solution onto the substrate in the chamber. A portion of the cleaning solution is thrown off the rotating substrate to form a cleaning solution mist in the chamber. A cleaning gas inlet introduces a cleaning gas into the chamber and an outlet exhausts the cleaning solution mist and cleaning gas from the chamber. This reduces the formation of residues from the cleaning solution mist on the substrate.
Abstract:
The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.
Abstract:
Antibacterial sol-gel coating solutions are used to form articles. The antibacterial sol-gel coating solution includes at least one Ti or Si-containing compound that is capable of hydrolyzing to form a base film; a regulating agent capable of regulating the hydrolysis rate of the Ti or Si-containing compounds, an organic solvent, water, and at least one soluble compound of an antibacterial metal, such as Ag, Cu, Mg, Zn, Sn, Fe, Co, Ni, or Ce.
Abstract:
One embodiment of the present invention provides a switch. The switch includes a local identifier associated with the switch, a receiving interface, a loop detection mechanism, and an interface control mechanism. The receiving interface identifies a loop-detection frame which includes an identifier associated with originating switch of the frame. The loop detection mechanism detects a loop based on a match of the identifier associated with the originating switch and the local identifier. The interface control mechanism is coupled to the loop detection mechanism and precludes, in response to detecting a loop, the receiving interface from forwarding frames corresponding to the loop.
Abstract:
One embodiment of the present invention provides a switch. The switch includes a local database, a packet processor, a data management module, and a tree construction module. The packet processor extracts spanning tree information associated with a remote switch. The data management module stores the extracted spanning tree information in the local database. The tree construction module assigns an interface state associated with a spanning tree to a local interface based on the extracted spanning tree information.
Abstract:
Disclosed are a method, device and system for establishing conversation relation, which relates to the field of internet and. The method comprises the following steps: local terminal recognizes the opposite terminal within a preset range and establishes NFC connection with the opposite terminal, both of local terminal and opposite terminal have NFC module installed and instant messaging application running; when touching is detected, local terminal initiates a NFC request to opposite terminal via NFC connection, obtain opposite terminal user ID and certificate, and sends request information to the server; the server establishes conversation relation between local terminal and opposite terminal according to request information. With the present invention, local terminal obtains opposite terminal user ID and certificate by touching, and sends request information which includes local terminal user ID, opposite terminal user ID and certificate to the server, so that the server can establish sessions between local terminal and local terminal without certification of both sides, it avoids the trouble of locating, verifying, establishing friendship via network before session between friends within touch effectively
Abstract:
Techniques for facilitating link redundancy using an enhanced version of Virtual Switch Redundancy Protocol (VSRP), referred to herein as VSRP2. In one set of embodiments, a group of Layer 2 and/or Layer 2/3 devices (switches) can act in concert as a VSRP2 virtual switch. A first switch in the group (a VSRP2 master switch) can forward, via a first link, data traffic to/from a network device in a connected Layer 2 network. A second switch in the group (a VSRP2 backup switch) can block, at a second link, data traffic to/from the same network device. If the first link fails or otherwise becomes unavailable, the VSRP2 backup switch can detect the link failure and begin forwarding, via the second link, data traffic to/from the network device. In this manner, redundancy can be provided at the link level between the VSRP2 virtual switch and the Layer 2 network.
