Title: Routing system for linear add-drop multiplexer
Inventor: TAKATSU KAZUO
IPC: H04J3/08
Filed: 1992-03-13
Granted: 1997-08-19
Abstract: A routing system for a linear add-drop multiplexer (ADM) having two drop switches, operates to establish paths according to a relatively simple process and to establish paths according to a program that is relatively small in scale and in-expensive to develop.  The routing system includes a first selection switch for selecting one of several channels connected to a first transmission line and for outputting a signal transmitted through the selected channel.  A first selector selectively outputs and inhibits the signal transmitted from the first selection switch.  The first selection switch and the first selector are provided in one of the drop switches.  A second selection switch selects one of several channels connected to a second transmission line and outputs a signal transmitted through the selected channel.  A second selector inhibits the signal transmitted from the second selection switch when the first selector outputs the signal, and outputs the signal when the first selector inhibits the signal.  The second selection switch and the second selector are provided in the other of the drop switches.          The signals are transmitted from the first and second selectors to a transmitter/receiver for lower signal levels.  The routing system of the invention operates to establish paths in a relatively simple, inexpensive manner.

Title: Apparatus and method for adaptively filtering a time-varying signal using multiple filtering algorithms
Inventor: BAKER JAMES C
IPC: H04L25/03
Filed: 1992-08-27
Granted: 1996-12-10
Abstract: The present invention presents an apparatus and method for recovering symbols in a data packet (101) transmitted to a receiver (201) from a remote signal source (202) in a time-varying channel using multiple adaptive filtering algorithms.  The symbols in the data packet (101) are recovered using an adaptive filter 203 responsive to a recursive least squares (RLS) filtering algorithm followed by a least-mean  squares (LMS) filtering algorithm.  The RLS filtering algorithm is used first for its fast training  and fast recovery characteristics. The LMS filtering algorithm is used second for its low complexity and high stability characteristics.  The switch between the RLS and the LMS filtering algorithms may be at a fixed point in time to ensure minimal filter complexity or may be adaptive responsive to the quality of an error  signal (ek) processed in a coefficient determinator (307 or 309) to ensure maximum bit error rate performance and stability.

Granted: 1996-11-12
Abstract: The breathing system comprises a canister (12) carrying layered filter-ing material, including activated carbon granules, a desiccant, a catalyst for the catalyzation of carbon monoxide to carbon dioxide, and electrostatically charged filters between the layers of filtering material. A mouthpiece (28) carrying a noseclip (33) and inhalation and exhalation check-valves and a whistle is disposed within a flexible, substantially completely transparent hear-through hood (34), both the mouthpiece (28) and hood (34) being dis-posed in the canister (12) between the filtering material and a cover for the canister. In use, the cover is removed, air inlet apertures are uncovered, and the hood (34) is drawn about an individual's head and substantially sealed about the neck. With the mouthpiece (28) in the individual's mouth, and no-seclip (33) closing off the user's nose, inhalation causes air to flow through the filtering material and the inhalation check valve and past the exhalation check valves. When exhaling, the exhalation check valves open to permit ex-haled air to flow into the hood. The inhalation valve closes during exhala-tion to prevent backflow of air through the filtering material. By exhaling in-to the hood (34), a slight positive pressure within the hood is established to prevent noxious gases, smoke particles and the like from entering the hood (34) through the neck opening (44).

Title: Dynamic access control for an atm network
IPC: H04Q3/00
Filed: 1994-08-22
Granted: 1999-03-09
Abstract: A facility is provided in an ATM network to track whether data traffic from a source is being admitted into the network in accord with associated traffic parameters. Such parameters are used to control the admission of traffic and aredynamically changed based on the level of congestion along an associated connection carrying such data. The level of congestion along the connection is determined by launching a particular type of cell over the connection and waiting to see if the destination and intermediate points along the connection return the cell to the sender, thereby indicating that the route of the connection is not congested. If the cell is not returned, then the facility concludes that the route is congested.

Granted: 1999-05-18
Abstract: A ball  louver  assembly  for  controlling  the  direction  of pressurized  air passing  through  the  openings  of  a  ball  shaped louver.  The ball louver mechanism comprises a ball louver liner, which holds the ball louver and liner inside and between front and rear retainer rings. An inner ring attached to the back edge of the front retainer ring allows the ball louver with its attached liner to be turned in any rotational direction to direct the forced air as desired. The structure of the ball louver and the liner allows the ball louver to be turned into a position to close, reduce or select the direction of the pressurized air leaving the air conditioner through the openings in the ball louver body.  This structure is similar to basic gyroscope axis principles in its mobility of the ball louver in any direction by incorporating a new liner with or without  spring-like  compression  effects  and/or  with  or  without notch-bump presence to help hold the ball louver in the last desired position  without  vibration  or  forced  air  being  able  to  cause movement of the ball louver from its last desired set position. Another feature in the liner gives compression spring-like increased coefficient of friction to the axle of the rotational ball louver to hold in the desired set position.

IPC: C12P21/02
Filed: 1994-05-03
Granted: 2004-09-28
Abstract: The hypervariable region (E2HV) of the putative hepatitis C virus (HCV) glycoprotein F2/NS1, between about amino acid 384 to about amino acid 414, is a rapidly evolving region of HCV, and is likely to be under positive immune selection. A newly discovered motif within this hypervariable region is immunogenic and conserved with respect to the character of the amino acids. In many isolates, this motif falls between amino acids 401 to 406 or 407. The discovery of this motif allows for additional materials and methods to treat and diagnose HCV.
