Granted: 1999-12-07
Abstract: In a wireless communication network a method for locating and tracking status of a plurality of radio ports comprises the steps of: determining a coordinate position of one of the plurality of radio ports; and transmitting the coordinateposition to a control center. The method can further comprise the step of removably interfacing a GPS receiver to one of the plurality of radio ports. Transmitting the coordinate position to the control center can utilize a wired connection. Additionally, the coordinate position can be stored at the control center. The coordinate position is integrated into a map of the plurality of radio ports. A nonresponsive radio port can be identified by a corresponding coordinate position and the wireless network traffic can be routed appropriately.

Title: Statistical database correction of alphanumeric account numbers for speech recognition and touch-tone recognition
Inventor: ROSINSKI RICHARD R
IPC: H04M11/06
Filed: 1997-11-19
Granted: 2002-03-05
Abstract: A method and apparatus for recognizing an identifier entered by a user. A caller enters a predetermined identifier through a voice input device or a touch-tone keypad of a telephone handset. A signal representing the entered identifier is transmitted to a remote recognizer, which responds to the identifier signal by producing a recognized output intended to match the entered identifier. The present invention compares this recognized identifier with a list of valid reference identifiers to determine which one of these reference identifiers most likely matches the entered identifier. In performing this determination, the present invention employs a confusion matrix, which is an arrangement of probabilities that indicate the likelihood that a given character in a particular character position of the reference identifier would be recognized by the recognizer as a character in the corresponding character position of the recognized identifier. This determination yields an identifier recognition probability for every reference identifier, and the present invention selects the reference identifier with the highest identifier recognition probability as most likely corresponding to the entered identifier.

Abstract: A method and apparatus permits concentration of a water-miscible organic liquid in a mixture of such liquid and water, with recovery of a desired concentrate of the water-miscible organic liquid and water, and a relatively clean water containing only a very low content of the water-miscible organic liquid which enables disposal of the water in sewage systems, the method and apparatus thus enhancing the ability to satisfy environmental concerns; the method has particular application to the recovery of a reusable glycol/water mixture from diluted spent aircraft deicer fluid (ADF).      The diluted spent ADF is heated in a plate heat exchanger with steam to form a hot frothing mass of liquid and steam which is delivered to a cyclone concentrator, the hot frothing mass in the plate heat exchanger and the cyclone concentrator are maintained at a first pressure and a steam phase including steam bubbles in the hot frothing mass is efficiently separated from and withdrawn from a hot liquid phase which represents a more concentrated glycol/water mixture. The steam withdrawn from the hot frothing mass is compressed to a second pressure higher than the first pressure and cycled back to provide the steam input of the plate heat exchanger.      After start-up the operation proceeds, with maintenance of the pressure differential, exploiting the heat of the compressed steam with no requirement for external heating. The method and apparatus may be applied to other aqueous fluid mixtures.

Abstract: A burner controller ( 10) for safe operation of a furnace has a an electromechanical latch (34) for holding first and second fuel valves (41, 42) open responsive to an enable signal. The latch comprises an armature (32) attached to the second valve (42) and an electromagnet assembly (33) attached to the first valve (41). When the electromagnet assembly (33) receives the enable signal and the armature (32) is attracted to the electromagnet assembly (33), the magnetic force opposes force of a spring (27) urging the first and second valve (41, 42) simultaneously closed. When the enable signal is not present, the spring forces (27) both valves (41, 42) into their closed position. An auxiliary valve (58) in series flow arrangement with the second valve (42) opposes flow of fuel passing through the second valve (42) in certain situations.

Abstract: Puits quantique d'AlxGA1-xAs/GaAs/Al Gxa AS1-x à transition à absorption inter-sous-bande, liée à quasi-liée. La transition-liée à quasi liée apparaît lorsque le premier état excité a la même énergie que le "sommet" (la barrière d'énergie supérieure) du puits quantique. La barrière d'énergie pour l'émission thermionique est ainsi égale à l'énergie nécessaire pour l'absorption inter-sous-bande. L'augmentation de cette manière de la barrière d'énergie permet de réduire le courant d'obscurité. La quantité de photocourant générée par le puits quantique est maintenue à un niveau élevé.

Abstract: A flexible package for a product includes a resealable closure for resealing one portion of the package to an opposing portion of the package. The resealable closure is formed by applying a layer of pressure-sensitive adhesive on the inner surface of at least one of the opposing portions of the package, and applying a layer of cohesive to the inner surface of both of the opposing portions so that the pressure-sensitive adhesive layer is covered by a layer of cohesive. The pressure-sensitive adhesive has a greater affinity for adhering to the cohesive than to the inner surface of the package. Accordingly, pressure-sensitive adhesive is detached from the inner surface of the package when the opposing portions are pulled apart, and the portions can be resealed by pressing the portions back together to cause the pressure-sensitive adhesive to adhere to the portion from which is was detached.
