Title: Method of making coated mat online and coated mat products
Inventor: JAFFEE ALAN MICHAEL
IPC: D21H23/28
Filed: 2002-08-06
Abstract: New coated nonwoven fibrous mats having properties particularly suited for a facer on gypsum wallboard and other substrates and in laminates of various types, and the method of making the coated mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The coating is preferably permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous coating methods, the coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.

Title: Apparatus for detecting arcing and overcurrents in dc electrical systems subject to cyclic disturbances
Inventor: SCHMALZ STEVEN CHRISTOPHER
IPC: H02H1/04
Filed: 2002-08-23
Abstract: Arcing in do electrical systems (1) subject to cyclic disturbances is detected by a current sensor (13), and a bandpass filter (17) sensitive to arcing noise, which filters the sensor current. The absolute value of the bandpass filtered signal (19) is integrated aver repetitive intervals in a resettable analog integrator (27). A  low cost microprocessor (25) samples and resets the analog integrator (17) at a frequency below the pass band and generates a time attenuated accumulation of the samples that produces an arcing signal if it reaches a predetermined limit. To improve nuisance immunity, the sensed do current (15) is compared in a high speed comparator (37) to the average sensed do current (35), and only samples taken by the microprocessor (25) during a predetermined time period after the sensed do current (15) exceeds the average sensed do current (35) in a predetermined manner are accumulated. The average sensed do current (35) is also used by the microprocessor (25) to provide overload protection.

Inventor: SCHMALZ STEVEN CHRISTOPHER
IPC: H02H1/00
Filed: 2002-12-18
Abstract: Tripping of a circuit breaker by an arc fault detector is blocked by a disable circuit upon detection of a transient associated with cold turn-on of an incandescent bulb powered by a dimmer. The peak value of pulses generated by the bandpass filter of the arc detector in response to step increases in the ac current is decayed approximately exponentially. The amplitude of each pulse is compared with upper and lower percentage limits of the decaying peak value. If the amplitudes of the pulses remain below the upper threshold for about 3 to 4 half cycles and exceed the lower threshold each half cycle, a dimmer transient is identified and logic is set to block generation of a false arc signal.

Abstract: A dual band multimode coaxial antenna feed has an inner section of longitudinal hollow waveguide having first and second orthogonal mode transducers that interface first and second orthogonally polarized cylindrical waveguide TE11 mode signals lying in a first upper (e.g.,Ka) frequency band.  An outer coaxial waveguide section has a Potter horn surrounding the inner waveguide section, which terminates at a polyrod. The outer section includes third and fourth orthogonal mode transducers that interface orthogonally polarized coaxial waveguide TE11 mode signals lying in a second lower (e.g.,X) frequency band. A tracking port coupled to the outer coaxial waveguide section provides an output representative of the difference pattern of the radiation profile produced by transverse electromagnetic TEM mode signals generated and propagating in the outer coaxial waveguide. A mode supressor in the outer waveguide section adjacent its two orthogonal mode transducers locally supresses TEM signals in their vicinity.

Abstract: L'invention concerne un procédé et un dispositif permettant d'établir des corrélations entre un paramètre donné et l'erreur propre à une mesure de pseudo-distance. On crée une base de données dans laquelle il est possible de déterminer l'estimation d'erreur correspondant à des mesures de pseudo-distance par rapport à une balise. On définit des groupes à cet effet. Chaque groupe est associé à une gamme de valeurs pour le paramètre considéré. On associe ensuite les mesures avec un groupe particulier sur la base de la valeur du paramètre considéré au moment (ou à-peu-près au moment) de l'exécution des mesures de pseudo-distance. Avec l'accumulation des estimations relatives aux mesures de pseudo-distance, il est possible de réduire la taille des groupes (c'est-à-dire la gamme des valeurs du paramètre considéré). La corrélation entre le paramètre considéré et les erreurs propres aux mesures de pseudo-distance fait qu'une réduction de la taille des groupes permet de réduire la variance des estimations d'erreur. La valeur moyenne des estimations d'erreur permet de corriger l'erreur dans les mesures ultérieures de pseudo-distance.
