Title: Method and apparatus for data transmission
Inventor: OKUNEV YURI
IPC: H04J11/00
Filed: 2000-07-13
Abstract: A method of providing a high bit rate DMT signal includes providing information on a plurality of DMT tones, with at least two of the plurality of DMT tones sending information in parallel. Of the tones sending information in parallel, at least one has a SNR too low to be individually used for the number of bits it is transmitting. Accordingly, the tones are coherently "combined" at the receiver in order to generate a SNR sufficient together to carry, at the desired BER, the number of bits being transmitted in parallel.  Two or more tones which alone cannot carry a single bit of information may be used together to provide a sufficient SNR at the receiver to transmit one or more bits. Similarly, two or more tones which alone cannot carry two bits of information, may be used together via parallel transmission to provide a sufficient SNR at the receiver. Further, the bit-carrying capacity of a first tone which can carry one or more bits may be increased by transmitting an increased number of bits in parallel with one or more additional tones which cannot carry any bits of information. According to another embodiment of the invention, rather than sending two or more DMT tones in parallel, one or more DMT tones are repeated over a plurality of DMT symbols, and "combined"  coherently in order to generate a SNR sufficient together to carry the number of bits being carried by the repeated tone.

Title: Anti-obesity material
Inventor: TAKEBE MINORU
IPC: A23L1/30
Filed: 2001-07-09
Abstract: Obesity inhibitory materials which are absorbed in the body via oral administration or dripping and affect causes of overeating. Thus, they can regulate food intake and thus promote the metabolism of lipids and inhibit t he accumulation of body fat without suppressing immune functions. At the same time, they can inhibit an increase in blood pressure, thereby surely inhibiting body weight gain (obesity). Such obesity inhibitory materials hav e never been reported hitherto. These obesity inhibitory materials having the above-described excellent effects are largely characterized by containing isoflavone aglycons and/or isoflavone glycosides.

Title: Parallel reactor with internal sensing and method of using same
Inventor: VAN BEEK JOHANNES A M
IPC: B01J19/18
Filed: 1999-08-12
Abstract: Devices and methods for controlling and monitoring the progress and properties of multiple reactions are disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight. Computer-based methods are disclosed for process monitoring and control, and for data display and analysis.

Title: A tcp proxy providing application layer modifications
Inventor: DOLSON DAVID
IPC: H04L29/06
Filed: 2002-06-27
Abstract: The invention disclosed is a Transmission Control Protocol (TCP) transport handler for a network intermediary. The handler examines all segments in a TCP/IP data Stream between two nodes. The handler maintains a list of changes made by an application module to a data segment within a data scream and utilizes that list to ensure that the sequence numbers for both receiver and transmitter refer to the same segments of data. The list of changes is also used to reapply changes to retransmitted packets. Data segments are not acknowledged until the receiver acknowledges a segment, eliminating the requirement of buffering data segments.

Abstract: In an electric or hybrid electric vehicle, a voltage monitor (102) is directly coupled to a traction motor (38) and/or generator motor (30) to detect a permanent magnet induced voltage within the motor at a predetermined speed and no load condition (300). A controller (100) compares the detected permanent magnet induced voltage with an expected reference voltage that represents an expected permanent magnet induced voltage at full magnetization and the predetermined speed (302). The controller produces an indication of magnetization based on the reference voltage, the detected permanent magnet induced voltage, and the predetermined speed.  If the indication of magnetism reaches a predetermined threshold, the motor is made inoperable and/or a current to the motor is limited to prevent damage to components (306, 308, 310, 312, 314). Preferably, a user of the vehicle is made aware of these actions by an audible and/or visual indicator (308, 314). If available, another source of motive power is substituted for the motor that is made inoperable (316).
