Abstract: A current distribution system, a current distribution method, and a computer system thereof are disclosed. The current distribution system includes a main control unit, a first power supply device, and a second power supply device. The main control unit is used for generating a first control command and a second control command. The first and the second power supply devices are used for receiving a first and a second power signals from a first and a second power input ends. The first and the second power supply devices adjust the first and the second power signals to a first and a second power shunt signals base on the first and the second control command and output to a load device, then the main control unit distributes a proportion of the first power shunt signal to the second power shunt signal accordingly.

Abstract: A directory server provides a media session channel for communication of real time streaming media data from a remote client to a client served by an address translation firewall. The directory server includes a client registration module for receiving a registration datagram originated by the client, source network address and a source port number from the registration datagram, and providing a session signaling message from the remote client to the client utilizing the extracted source network address and source port number.

Abstract: A device provides for sending datagrams representing real time streaming media frames to a client independent of whether the client is served by a network address proxy. The device receives a datagram originated by the client that includes an indicated network address and an indicated port number for receipt of the datagrams representing real time streaming media frames, extracts a source network address and a source port number from the datagram originated by the client, and compares the indicated network address to the source network address. The device addresses the datagrams representing real time streaming media frames to the source network address and source port number if the indicated network address and the source network address are not the same.

Abstract: A method for communicating real time media data between a first client and a second client across a packet switched data network is provided. The method includes receiving an indication of a first client network address for use as a destination network address for sending media datagrams to the first client. A media datagram originated by the first client is also received. A comparison between the first client network address and a source network address extracted from the media datagram originated by the first client is made. A media datagram is sent to the first client using the source network address if the source network address and the first client network receiving address are not the same and the media datagram is sent to the first client using the first client network address if the source network address and the first client network address are the same.

Abstract: A method of audio communication between a first telephony client located behind a network address translation (NAT) server and a remote second telephony client is disclosed. A calibration datagram is sent from the first telephony client to the second telephony client on a user datagram protocol (UDP) channel identified for sending audio data. The second telephony client extracts the source address and port number to identify a reverse UDP channel for sending audio data to the first telephony client.

Abstract: An Internet Protocol (IP) appliance and a method of using such appliance is disclosed. The IP appliance includes an IP telephone, an IP appliance universal connector and a network connector. A handheld device can be operationally connected to the IP appliance via the IP appliance universal connector to transmit and receive data over an IP network and/or a PSTN network.

Abstract: The present invention relates to displaying caller ID information, and more specifically, to displaying caller ID information in an environment with broadband telephony service. The invention provides a method and apparatus for receiving caller ID information from a service provider and providing the caller ID information for display as an overlay over a television programming image provided by the service provider and displayed on a television.

Abstract: A tunneling address translation engine enables a Internet protocol packet audio conversation to be maintained between two device. At least one of the devices may be behind a firewall or behind a network address translator, or proxy server. The tunneling address translation engine routes frames of audio data to an intended destination utilizing unreliable data protocols which do not include source address information. An audio conversation may be maintained through a sequence of tunneling address translation engines.

Abstract: By providing subpixel accuracy in the detection of the position of an element of a pixel data image, the invention makes possible reductions in scanner and storage resolution of the order of 65 percent or greater for two-dimensional applications. Methods use normalized gray level values to determine the extent of coverage of an image cell by individual pixels. By then applying such gray level values of a plurality of successive pixels to a preconstructed lookup table, ambiguities are resolved to determine the position of cell edges. The cell edge data can be used to determine cell position or used directly in edge-based bar code decoding techniques. Cell position data is used for construction of a virtual image of a bar code or other dataform of interest and virtual image information may then be used for purposes of decoding the bar code or other dataform.

Abstract: A portable non-contact label imager captures an image of two-dimensional information indicia on a label. The captured image data is decoded by a decoder. The label imager forms a part of a data terminal, which includes a keypad, display and signature capture pad. Upon receipt of a start signal from the data terminal's circuitry, the label imager automatically carries out the steps required to capture the label information indicia. The label imager provides aiming indicia to allow the user to properly aim the camera. A position sensing device determines when the target label is within the camera's depth of field. At that time, the label imager determines the shutter speed required for a correct exposure by measuring the light reflected from the label. The label imager then captures the label image, which is decoded by the decoder. Corresponding output data is then provided to the data terminal.
