20110051645	SENSOR NETWORK SYSTEM AND COMMUNICATION METHOD THEREOF - Provided are a communication method and system for sensor network. In reporting event occurrence in a real-time sensor network application, a cycle time is divided into an event announcement period and a data transmission period to provide real-time transmission performance and energy efficiency. Each of the periods is again divided into the number of slots equal to the maximum depth of a network. Respective nodes sequentially operate according to their depths in a routing tree during the event announcement period to receive the signal transmitted from the lower node. To remove sleep delay, a slot next to the signal reception slot becomes a signal transmission slot. A node sensed an event transmits a signal informing event occurrence during its signal transmission slot, and this signal includes only the address of the transmission node. When a signal does not exist in the event announcement period, no traffic occurs in the data transmission period and the upper nodes maintain a sleep state. When a signal is transmitted during the event announcement period, nodes transmitting/receiving a corresponding signal operate during the data transmission period to transfer data packets.	03-03-2011
20090191524	Method and apparatus for analyzing pattern colorings and evaluating psychological status or disorders in art therapy - A method and apparatus for analyzing pattern colorings and evaluating various psychological symptoms or disorders in art therapy are disclosed.
