Abstract: The present invention relates to a radiation inspection apparatus for object security inspection, comprising: a ray generator configured to emit a ray, a collimator configured to collimate the ray emitted from the ray generator, and a detector configured to receive the collimated ray collimated by the collimator, wherein the collimated ray forms an irradiated area on the detector included by an effective detect area of the detector. The present invention also relates to a method of performing a security inspection to a body using a radiation inspection apparatus. With the above technical solutions, the present invention can achieve a low single inspection absorptive dose and a micro dose inspection while meeting inspection requirements to improve public radiation security.

Abstract: A method and apparatus for dealing with a request from a user for leaving and zapping a multicast service channel in a network access apparatus, which supports the multicast service, are provided in this invention. A new state, i.e. unused state, is introduced to implement a slow leaving mechanism. When the last user of a multicast group leaves the group, the group will be set into the unused state instead of being deleted immediately, and a period of reserve time is set for the specific group. If there is any user requesting for joining the group within the period of reserve time, the group will be set back into the active state, otherwise the group will be deleted. This mechanism avoids frequent switching requests from the network access apparatus to the network, relieves the heavy load of the network due to the users' frequent zapping requests and hence improves the network performance.
