摘要： An electrical connector comprises an insulative housing, a printed circuit board retained in the insulative housing, and a limiting member. The insulative housing has a mating portion and a main portion extending backwards from the mating portion. The printed circuit board has a tongue portion exposed in front of the mating portion and a plurality of golden fingers disposed on the tongue portion for mating with a complementary connector. The limiting member defines a pair of first limiting plates parallel and opposite to each other. The first limiting plates are located in front of the mating portion entirely and on both sides of the tongue portion in a transverse direction, a first guiding slot is formed between each first limiting plate and corresponding lateral surface of the tongue portion in the transverse direction for leading the complementary connector to be plugged.

摘要： A service virtual machine provides service to any number of virtual machines on a hypervisor over a first communication channel. When an anomaly is detected within the provided service, any virtual machine using the first communication channel switches to a second communication channel and receives service from a second virtual machine. The second virtual machine may execute upon the same computer or on a different computer. Hooking points within the hypervisor provide a means for the service virtual machines to monitor traffic and provide service to the protected virtual machines. When a service virtual machine is suspended, it is repopulated, upgraded or rebooted, and then restored to service. Once restored, any protected virtual machine may be switched back to the restored service virtual machine. Virtual machines may be switched to a different communication channel by modifying a configuration file. Both communication channels may be in use at the same time.

摘要： Embodiments of the present invention generally relate to a method and system of channel feedback in wireless communications. Specifically, according to embodiments of the present invention, there is provided a two-stage Co MP feedback mechanism, such that different types of channel feedback are transmitted in each stage. Specifically, during the first stage, information regarding long-term features and/or wideband features of a channel is fed back; while during the second stage, information regarding short-term features and/or narrow features of channel is fed back. The first stage and the second stage may be periodically repeated. The information fed back during the first and second stages are used to calculate feedback information characterizing a joint-channel feature. In this way, overheads associated with channel feedback may be effectively reduced. Corresponding methods and apparatuses are also disclosed.
