Abstract: Provided is a walking supporting apparatus for supporting a user walking by using a multi-sensor signal processing system that detects a walking intent. A palm sensor unit detects a force applied to a palm through a stick to generate a palm sensor signal. A sensor unit detects a force applied to a sole through the ground to generate a sole sensor signal. A portable information processing unit checks a user's walking intent by using the palm sensor signal, and if it is checked that the user has a walking intent, the portable information processing unit generates a driving signal in response to the sole sensor signal. A walking supporting mechanism includes a left motor attached to a user's left leg and a right motor attached to a user's right leg to support the user's walking when the left and right motors are driven in response to the driving signal.

Abstract: A network communication system and a method of controlling the network communication system are provided. The network communication system includes: a member reading at least one piece of data stored in an access point (AP); a member giving priority to the data; a member re-transmitting the data having the priority to the AP; and a member processing the data in the AP according to the priority. Thus, data can be efficiently processed according to predetermined priority using a low-end type AP as a high-end type AP is used.
