A technique dynamically utilizes a plurality of multi-homed Virtual Private Network (VPN) tunnels from a client node to one or more enterprise networks in a computer network. According to the technique, a VPN client node, e.g., a “spoke,” creates a plurality of multi-homed VPN tunnels with one or more servers/enterprise networks, e.g., “hubs.” The spoke designates (e.g., for a prefix) one of the tunnels as a primary tunnel and the other tunnels as secondary (backup) tunnels, and monitors the quality (e.g., loss, delay, reachability, etc.) of all of the tunnels, such as, e.g., by an Optimized Edge Routing (OER) process. The spoke may then dynamically re-designate any one of the secondary tunnels as the primary tunnel for a prefix based on the quality of the tunnels to the enterprise. Notably, the spoke may also dynamically load balance traffic to the enterprise among the primary and secondary tunnels based on the quality of those tunnels.

The invention relates to an air conditioner and a defrosting control method thereof. According to the defrosting control method, whether defrosting control needs to be conducted or not is judged by the way of judging the relation between outdoor environment temperature and outdoor coiled tube temperature, and the optimization time point for entering in the defrosting control can be accurately judged. After the defrosting control is conducted, the frequency of a compressor is changed, and after switching frequency is reached, a four-way valve is directly switched to conduct defrosting control. After defrosting is completed, the frequency of the compressor is changed, and after the switching frequency is reached, the four-way valve is directly switched so that defrosting operation can be achieved. By means of the air conditioner and the defrosting control method thereof, the precision for entering in and exiting out of defrosting can be guaranteed, meanwhile, due to the fact that halting can not occur to the compressor in the defrosting process, heating capacity attenuation caused by halting of the compressor is reduced, the defrosting cycle is shortened, and the heating comfort and the heating performance of the air conditioner are improved.

The present invention relates to curing light devices for use in dentistry. Specifically, this invention relates to curing light devices generating convergent and uniform light with high intensity. The curing light device has a handle portion and a front portion wherein a light module is located in a desirable position in the interior of the front portion. The light module may include a light source comprising at least three LEDs in a compact manner, an optical element adapted to direct and/or focus the LEDs, and a lens cap to protect the LEDs and the optical elements. The lens cap may include a peripheral groove extending more than half of the periphery of the lens cap, which provides a longer engagement portion and thus a more secured attachment when “over-centeredly” engaging with a receiving edge on the light emitting end. A substantially precise alignment is achieved between the LEDs and corresponding lenses on the optical element to minimize heat dissipation and to increase the runtime and intensity of the curing light device. The curing light has an effective beam diameter of at least about 9 mm with output homogeneity of up to about 6 mm away from the emitting end.
