Method and Apparatus for Providing Data Processing and Control in a Medical Communication System

A method for inline intrusion detection includes receiving a packet at a network gateway, storing the packet, and assigning an identifier to the packet. The method also includes transmitting a copy of the packet and the identifier from the network gateway to an intrusion detection system and analyzing the copy of the packet by the intrusion detection system to determine whether the packet includes an attack signature and communicating a reply message from the intrusion detection system to the network gateway. The reply message includes the identifier and is indicative of the results of the analysis. The size of the reply message is less than the size of the packet.

Systems and methods for providing dynamic changes to a packet flow in a communication network are described. The dynamic changes can include upgrading and downgrading quality of service (QoS), adapting the stream to a receiving device, modifying the stream to counter-act changes in an air interface, and modifying the stream to accommodate an inter-technology handover. These changes can be provided by inspecting packets at a gateway and setting up a proxy for multimedia stream packet flows. The proxy can coordinate transcoding to take place to change the stream. The gateway can also monitor conditions at the mobile node using a real time control protocol or other applicable protocols.

This letter presents the design for a low- profile planar inverted-F antenna (PIFA) that can be stuck to metallic objects to create a passive radio frequency identification (RFID) tag in the UHF band. The designed PIFA, which uses a dielectric substrate for the antenna, consists of a U-slot patch for size reduction, several shorting pins, and a coplanar waveguide feeding structure to easily integrate with an RFID chip. The impedance bandwidth and maximum gain of the tag antenna are about 0.3% at 914 MHz for a voltage standing wave ratio (VSWR) of less than 2 and 3.6 dBi, respectively. The maximum read range is about 4.5 m as long as the tag antenna is on a metallic object.

The present invention provides a Session Initiation Protocol (SIP)-based load balancing apparatus and method. The apparatus receives a message transmitted from a user at a position in front of a plurality of proxy servers each connected in parallel and decodes the received message. The apparatus selectively performs addition, renewal and deletion of user information according to an expiration field of a header and transmits the decoded message to a proxy server, if the decoded message is a REGISTER message, searches for a proxy server that will handle a destination address, increases a load of the proxy server and transmits the decoded message to the proxy server, if the decoded message is a INVITE message, and examines a proxy server of the destination address and transmits the decoded message to the proxy server, if the decoded message is a BYE message.

The present invention provides a method of providing Differentiated Service (DiffServ) based Quality of Service (QoS) to Voice over Internet Protocol (VoIP) packets through a router. In the QoS providing method, VoIP call session information including source and destination IP addresses, source and destination user datagram protocol (UDP) port numbers, and requested QoS information is provided to the QoS control server by the VoIP call control device. Source and destination routers are found using the VoIP call session information and the VoIP call session information requiring provision of QoS is sent to the source and destination routers by the QoS control server. The present invention can recognize VoIP packets, provide QoS to the VoIP packets, and transmit voice packets of high quality.

An RFID tag includes an antenna and a chip, and the antenna includes a first polygonal dielectric material, first and second microstrip lines partially formed in the first dielectric material, a second polygonal dielectric material stacked on the first dielectric material, and a third microstrip line partially formed in the second dielectric material. According to the present invention, the RFID tag can efficiently receive electromagnetic waves to thereby maximize a readable range.

Radio frequency identification tag and radio frequency identification tag antenna

A battery-powered RFID tag capable of reducing power consumption and a method of waking up the RFID tag are provided. The battery-powered RFID tag has an activated mode where a general command is detected by decoding a signal received from an RFID tag reader and the general command is executed and a standby mode where the general command is not detected. If a voltage of a continuous wave detected from the signal is equal to or higher than a predetermined voltage or if a wake-up command is detected from the signal, the state of the RFID tag is changed from the standby mode to the activated mode. In addition, the RFID tag is driven by a higher one between the voltage of the continuous wave and a voltage of a built-in battery.
