The present disclosure illustrates a non-contact measurement device for a radius of curvature and a thickness of a lens and a measurement method thereof. The non-contact measurement device utilizes a non-contact probe to integrate a motor, an optical scale and an electronic control module, so as to achieve measurement for the radius of curvature and the thickness of the lens. The present disclosure adopts astigmatism to achieve fast and precise focusing. To overcome the spherical aberration problem, thickness measurement can be implemented by the non-contact measurement device through a formula calculation and utilization of a correction plate, wherein single one probe is used for the measurement herein. For the thicker lens, the non-contact measurement device can be extended to use dual probes, so as to detect the top and bottom sides of the lens.

A method for post-authenticating user equipment (UE), a controller and a network system are disclosed. The method includes: determining whether an external channel quality of at least one gateway is higher than a threshold when UE connects to an access point (AP) routed by the gateway; when the external channel quality is not higher than the threshold, authenticating the UE incompletely and controlling the AP to limit a network capability providing to the UE; estimating a future channel capacity of the gateway; calculating a priority weight of each UE; selecting candidate UE from the UEs according to the future channel capacity and the priority weight of each UE; arranging an authenticating mechanism for completely authenticating the candidate UE at a timing point corresponding to the future channel capacity.
