Title: Packet data communications system having a malfunction list
Inventor: PONTUS LINDQVIST
IPC: H04L12/56
Filed: 1997-04-28
Granted: 1997-10-11
Abstract: A packet switching network having a malfunction list is provided to reduce network congestion. According to an exemplary embodiment, each node in the network includes a malfunction list which stores an unavailability value representing a state of unavailability of certain addressees in the network. Before sending a packet to an addressee, the node consults its own malfunction list to determine the unavailability value of the addressee. A packet addressed to an unavailable addressee is selectively returned to the sender by the node rather than travelling through the network to the addressee and back through the network to the sender. Packets can be returned to the sender with a probability proportional to the unavailability value of the addressee so that transmission is gradually resumed after a state of unavailability as the unavailability value decreases over time.

Title: Method for simulating a computer storage device
Inventor: BEELITZ ALAN E
IPC: G06F9/445
Filed: 1998-07-27
Granted: 2000-09-01
Abstract: A system and method for re-mapping a logical reference to a computer storage device to another storage device. The computer includes a processor for running operating system code, RAM, and a hard drive memory device. The computer does not, however, have a floppy disk. The hard drive, which can be accessed by the processor, includes at least two partitions. When the computer boots up, operating system code running on the processor includes a first logical reference to the first partition of the hard drive and a second logical reference to the non-existing floppy disk. The logical references are stored in a table, located in RAM. If software routines running on the processor ever use the second logical reference, an error would normally occur. However, a reference-changing routine is provided for changing the logical reference from the non-existing floppy disk to the second partition of the hard drive. The reference-changing routine does this by altering the table with data from the second partition so that when the logical reference to the second storage device is used, the second partition of the first storage device is accessed.

Title: A super-lattice negative-differential-resistance transistor
Inventor: LIOU WEN-CHAU
IPC: H01L29/66
Filed: 1998-07-27
Granted: 2000-03-11
Abstract: The present invention relates to a super-lattice negative-differential-resistance transistor as a novel, high-speed, low power resonant tunneling device which functions as negative-differential-resistance (NDR) transistor. The device has both characteristics of the transistor amplification and remarkable negative-differential-resistance. In the device, the emitter area includes the super-lattice negative-differential-resistance transistor having 5-cycle periods of GaInAs/AlInAs). Because the emitter-base is a homogeneous junction, the compensation voltage of collector-emitter, V<CE, offset>, may be reduced significantly. Furthermore, using valence band discrete value, <delta>(EV), as an effective barrier of electro-hole, provides significant reduction of base current, while improving the emitter injection efficiency of emitter so as to achieve high current gain. On the other hand, using multi-potential barrier model and transmission matrix, to discuss the carrier transmission in GaInAs/AlInAs super-lattice resonant tunneling layer to suggest the existence of a subband in the super-lattice area. The test result shows that under room temperature, the invention would perform perfectly in forward-active as a sound transistor, the N-shaped NDR would be found in saturation region. Therefore, the invented device has excellent transistor amplification effect in forward-active area; furthermore, the N-shaped NDR is also discovered in saturation area. Thus, the invented device can be immediately applied in microwave, high speed and low power, multi-value logic and amplifier circuits.
