Title: Network address translation gateway for local area networks using local IP addresses and non-translatable port addresses
Inventor: SULTAN ISRAEL DANIEL
IPC: H04L12/66
Filed: 2000-11-23
Granted: 2002-07-11
Abstract: A network address translation gateway provides normal network translation for IP datagrams traveling from a local area network using local IP addresses to an external network, but suspends source service address (port) translation when the port is reserved for a specific protocol, such as the ISAKMP ""handshaking"" protocol that is part of the IPSec protocol model. ISAKMP exchanges require both source and target computers to use the same service address (port). By providing a network interface that does not translate the source service address (port), this gateway enables the initiation and maintenance of secure, encrypted transmissions using IPSec protocol between a local area network using local IP addresses and servers on the internet.

Title: Data transmission controller, information memory medium and electronic machine
Inventor: MATSUNAGA KOSUKE
IPC: H04L12/64
Filed: 2000-12-19
Granted: 2002-11-01
Abstract: The present invention provides a data transmission controller, an information memory medium and an electronic machine. The object is to clear the topology information of segments for eliminating the unmatched effect during resetting. In the data transmission controller with IEEE 1394 specification, when the bus is reset during data transmission and the ORB contents before and after resetting of the bust are the same, the data will be re-transmitted from the occurrence of resetting of the bus, so as to prevent the double printing of the printer. When the resetting of the bus is occurring during the data transmission, it will be labeled as ON state. After the resetting of the bus, the command block ORB containing the printing command transmitted initially is used as the reference of the ORB before the resetting of the bus. When the bus is reset and the ACK is not returned by the initialization program, the status will be transitioned as the standby state. During the data transmission for the scanner, the initialization program during the occurrence of the resetting of the bus will keep, rather than abandon, the transmission data to be transmitted.

The acoustic signal is provided to an acoustic processor. An output waveform is formed from the acoustic processor by adjusting the attenuation factor from a muted state to a first attenuation value associated with the non-muted state. After the attenuation factor is adjusted to the first attenuation value, the output waveform is formed by gradually changing the attenuation factor from the first attenuation value to a second attenuation value.

Abstract: The present invention proposes a vertical dual-transistor memory cell structure that contains a MOS transistor and an EPROM tunneling oxide (ETOX) memory cell. One of the drain and source of the MOS transistor is connected with the control gate of the ETOX memory cell, and the other one of the drain and the source of the MOS transistor is used as the control gate of the memory cell structure and is connected with a control line. Gate of the MOS transistor is used as the selection gate of the memory cell structure and is connected with a word line. Drain of ETOX memory cell is connected with the bit line, and source of the ETOX memory cell is grounded. A programmable process can be conducted onto the memory cell through the use of Fowler-Nordheim tunneling electron of channel region such that electron can penetrate channel region and tunnel oxide till reaching the floating gate. In addition, the problem of word line interference can be prevented through the control of the word line. The memory of the memory cell can also be erased through the use of Fowler-Nordheim tunneling electron of channel region such that the electron stored at the floating gate can be pulled out to penetrate tunnel oxide as well as channel region till reaching the substrate. Furthermore, the other conventional method can also be used to conduct the programmable process onto the invented memory cell, for example, by shooting hot electron or Fowler-Nordheim tunneling electron of drain to conduct programmable process, and using the methods such as negative gate voltage and source erasion or Fowler-Nordheim tunneling electron of drain to conduct the process of erasing memory.
