Title: Round-trip delay optimization of multiplexed speech channels
Inventor: VALKO ANDRAS
IPC: H04L12/56
Filed: 1998-05-16
Granted: 2001-11-21
Abstract: Data packets are transmitted in forward and backward directions via a multiplexed communications medium, wherein each of the data packets is associated with a corresponding one of a plurality of connections. Transmission is performed by, for each connection, assigning a forward delay limit and a corresponding backward delay limit, wherein the sum of the forward and backward delay limits is equal to a round-trip delay bound for the connection. The assigned forward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the forward direction. Similarly, the assigned backward delay limits are used to determine the order in which the data packets supplied by the plurality of connections will be transmitted in the backward direction. One embodiment accomplishes the forward the backward delay limit assignments by maintaining forward and backward lists of connection identifiers sorted in, for example, ascending order based on time of connection establishment in the forward direction, and in descending order based on time of connection establishment in the backward direction. In another embodiment, transmission order is determined by sorting arriving data packets at the time of their corresponding connection identifiers, wherein the forward and backward sorting rules are selected so that a sum of a forward transmission delay limit and a backward transmission delay limit is less than or equal to a round-trip delay bound for each connection.

Title: Gateway allowing coexistence of virtual network and physical network and the control method thereof
Inventor: LIN JIUN-NAI
IPC: G06F15/173
Filed: 1998-05-19
Granted: 2001-09-21
Abstract: The present invention relates to a gateway allowing coexistence of virtual network and physical network and the control method thereof where only a single physical port is required for the connection with the virtual network and the physical network in the local network. Conceptually, the physical port can provide two logical ports, wherein one is set as the address of the virtual network's Internet Protocol (IP) and the other is set as the address of the physical network's IP. No matter it is in the virtual or the physical network, the gateway is set as a default gateway by the host. The present invention will automatically determine whether a data packet is transmitted from the host of the virtual network or the physical network. If it is a data packet transmitted from the host of the virtual network, the gateway will carry out network IP address translation (NAT) before transmitting it to the Internet. If it is a data packet transmitted from the host of the physical network, the gateway will only forward it to the Internet. Besides, through the gateway, data packets may be transmitted between the host of the virtual network and the host of the physical network.

Granted: 2002-07-11
Abstract: It is desired to prevent disalignment of the edges of a folded sheet by smoothly feeding the sheet while keeping tension fluctuactions to a minimum when the sheet is unwound from a paper roll set in a paper feed unit to a packaging unit even though, the paper roll diameter decreases gradually as the sheet is unwound. A sheet length measuring sensor or rotary encoder is provided in the paper feed path through which the packaging sheet unwound from the paper roll is fed toward the packaging unit. An angle sensor is provided which comprises Hall element sensors provide on a support shaft and magnets provided on a core pipe of the paper roll. Any change is the signals from one of these sensors relative to the signal from the other sensor is used to calculate the paper roll winding length, and the sheet tension is adjusted to an optimum, constant level by controlling the sheet braking force stepwise according to the roll diameter measured by the sensors.

Filed: 1999-04-23
Granted: 2000-11-01
Abstract: To provide a conducting path between the metal_0 layer and a metal_1 interconnect layer, two layers with conducting plugs were necessary in the prior art. In the present invention, the conducting regions (14') electrically coupling two regions of the integrated circuit are formed at the same time as the formation of the conducting plugs (14) coupling selected portions of the integrated circuit with the metal_1 interconnect layer (27). The conducting regions (14'), as with the conducting plugs (14), extend to surface of the insulating layer (12) upon which the metal_1 interconnect paths (27) are patterned. Using this technique, process steps required in the prior art can be eliminated. This process has the limitation that metal_1 interconnect layer can not be formed over the conducting regions.

Title: Authentication system and method
Inventor: KOSTRZEWSKI ANDREW A
IPC: G06E3/00
Filed: 2000-08-01
Granted: 2002-04-21
Abstract: An authentication system using a correlator that correlates an input with a reference wherein at least one of the input and reference comprises a phase volume mask having structures, preferably points, that are each less than about six microns in size and can have an aspect ratio (AR) greater than 1:1 so as to produce a phase encoded random pattern having millions of combinations in a mask that is as small as one square millimeter. The random pattern can be convolved with a second pattern, such as a biometric pattern, to produce a phase convolved mask. The correlator preferably is a nonlinear joint transform correlator that can use ""chirp"" encoding to permit the input to be located in a different plane than the reference. The correlator optically Fourier transforms images of the reference and input that are thereafter nonlinearly transformed and inverse Fourier transformed by a processor to determine the presence or absence of a correlation spike indicative of authenticity. A spatial light modulator (SLM) can be used as an input or reference and preferably is a liquid crystal panel having pixels or elements whose phase or grey scale intensity can be selectively controlled by a processor. The SLM can be used to display a biometric pattern, preferably scanned in real time from a person, that is correlated against an input or reference that can comprise a label on a card, a tag, or another object.
