Abstract: A shock fatigue testing device for a powertrain mount includes: a main frame having a guide support vertically extending from a base plate and a mounting plate coupled to the guide support; a first mount jig mounted to the mounting plate and configured to support the upper portion of a mount member; a second mount jig mounted to a lower portion of the mount member and configured to support the lower portion of the mount member; a weight portion fixed to the second mount jig and configured to apply a load to the mount member; and a vibration portion configured to continuously provide vibration to the base plate to vibrate the weight portion using the main frame, the first mount jig, and the second mount jig as media.

Abstract: A method for efficiently processing traffic in an intermediate access point such as a relay station is disclosed. To process traffic directed from one or more terminals to a base station, an intermediate access point supporting two or more communication scheme receives traffic from the one or more terminals according to a first communication scheme, measures a congestion level of the received traffic, transmits a first traffic being part of the received traffic to a second intermediate access point according to a second communication scheme, if the congestion level is equal to or higher than a predetermined threshold, and transmits a second traffic being remaining traffic of the received traffic except the first traffic to the BS.
