Patent number: 8125317Abstract: A portable device includes an RFID reader for detecting a tag information of an RFID tag, a memory for storing the tag information detected by the RFID reader, and a controller. When a read command for the RFID tag is input and the tag information is valid, the controller controls the RFID reader to retrieve the tag information of the memory. If the tag information is invalid, the controller controls the RFID reader to re-read the RFID tag. The controller can determine whether the tag information is valid using the time and location. Because unnecessary operation can be omitted to read tags, power consumption is reduced and tag information check time is shortened.Type: GrantFiled: March 14, 2006Date of Patent: February 28, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Hyung-min Yoon, Kyung-ho Park, Woo-shik Kang

Patent number: 7660860Abstract: A method for determining a transmission time of collected context information at a sensor node in a communication system that includes a client, at least one sensor node collecting context information, and an access point (AP) forwarding the context information received from the sensor node to the client. The communication system operates in a session layer of protocol layers of open systems interconnection (OSI). The sensor node calculates a transmission period in which the collected context information is transmitted, and randomly determines a transmission time at which the context information is transmitted within the calculated transmission period. Since the collected context information is transmitted at the transmission time randomly determined by the sensor node, the load on the AP can be balanced.Type: GrantFiled: November 14, 2005Date of Patent: February 9, 2010Assignee: Samsung Electro-Mechanics Co., LtdInventors: Hyung-min Yoon, Tack-don Han, Beom-seok Kang, Kyung-ho Park, Woo-shik Kang
