Title: Multiple wavelength laser source
Inventor: ATIEH AHMAD
IPC: H04J14/02
Filed: 2001-03-21
Abstract: A simple and flexible WDM laser source is disclosed using a loop erbium-doped fiber amplifier (LEDFA) configuration. The loop serves as a mirror and as an amplification medium. The laser cavity was made from the loop mirror and a set of fiber Bragg gratings (FBGs) which select the proper lasing wavelengths. The FBGs can be placed either in parallel or in series at the output of the loop configuration. Optical attenuators are placed in front of the FBG to control the flatness of the laser source output and determine the required lasing condition for each wavelength to avoid competition of the different lasing wavelengths. This configuration is flexible for adding any number of wavelengths as long as enough amplified spontaneous emission (ASE) is generated in the loop. Signal to noise ratio as high as 55-dB can be achieved.

Abstract: A system and method for controlling a damping system. The system has at least two dampers for damping between sprung (207) and unsprung masses (202, 204, 206) in the compression and rebound directions. Sensors generate signals based on position (224) and other parameters of motion representative of the displacement between the sprung and unsprung masses. The process determines the appropriate compression and rebound forces to be applied at the wheels (202). A regulator responds to at least one of the independent compression and rebound control signals for adjusting, respectively, at least one of compression and rebound resisting forces of the dampers between the masses.  Compliance for the dampers is emulated with software to produce the desired compliance forces. The distributed controller includes a processor that is responsive to signals representative of the position signals for forming the compression and rebound control signals for the regulator as a function of motion between the masses or a motion of a vehicle in which the dampers are located. The system has the capability of locking the suspension when parked.

Title: Gas conducting system with filter for moisture removal
Inventor: BINDER WALTER
IPC: B01D46/42
Filed: 2001-08-09
Abstract: A gas conducting system, particularly a compressed air system for a motor vehicle, which includes a filter containing a desiccant for removing moisture from a gas passed therethrough. The housing structure of the filter is provided with a seal with a weakened area 18, which specifically causes any overpressure to be reduced through failure of the weakened area if the pressure inside exceeds a permissible maximum. This process can be repeated multiple times until the seal with the weakened area 18 must be replaced due to aging. The weakened area can be used as a substitute for a pressure relief valve or as supplemental protection in case the pressure control valve fails, e.g., due to ice. This can prevent, for instance, bursting of the filter housing which could present a safety risk.

Title: Wrap around booster
Inventor: FERGUSON MARK ALLEN
IPC: F24D17/00
Filed: 2001-11-14
Abstract: The present invention relates to a wrap around booster (10), and more specifically, the present invention relates to a wrap around booster (10) for use with a high temperature dishwashing machine (40). The wrap around booster (10) heats the water of the dishwashing machine (40) from approximately 110-140°F to at least 150°F in the wash tank (11) and at least 180°F in the rinse tank (26). This is accomplished by keeping a relatively constant volume of water in the rinse tank (26) containing the wrap around booster (10), which maintains the rinse tank water at least 180°F. The rinse tank water surrounds the wash tank (11). The warmer water in the rinse tank (26) surrounding the wash tank (11) therefore heats the water contained in the wash tank (11) through convection. Therefore, one heating system does the work of two heating systems. Because there is no heating system inside the wash tank (11), the entire tank of water can be dumped and then the water is replenished with the water used during the rinse step.
