Abstract: An alarm system uses the menacing sounds of a dog to scare away intruders. The alarm system includes a microphone for detecting noise, a comparator for comparing the detected noise level to a reference level so as to determine whether the detected noise is a potential intruder, sound recordings of different excited dogs, and a speaker for broadcasting a user-selected recording. A controller initiates broadcasting of a selected recording if the comparator determines that a detected noise is an intruder.  The controller varies the volume of the broadcast recording to simulate movement of a dog about the interior of a dwelling or enclosure.

Abstract: A horizontal combined air intake and combustion gas vent terminal assembly is provided having improved wind pressure response and anti-recirculation characteristics. The terminal has a vent conduit disposed inside an air intake conduit. A scoop assembly is provided at the intake conduit inlet to increase the intake air pressure at the inlet. The vent conduit is nozzle-like to throttle combustion gases, thereby accelerating the gases and permitting the terminal to project the gases away from the intake conduit terminal. Vent conduit is disposed asymmetrically with intake conduit to further discourage mixing of intake air and combustion gases. The terminal may also be provided with a static pressure measuring means to provide an intrinsic safety shut down system within the terminal in case of blockage of the intake or vent by snow, ice or other debris.

Abstract: A hydraulic pump assembly (10) for powering a hydraulic torque wrench (24) i s air-powered and has hydro-pneumatic control circuitry (39) which continues operation of an air motor (18) which drives t he hydraulic pump (16) for a post-advance period after an advance actuator (55) is deactuated. Operation of the pump (16) is continued for a period sufficient to retract a double-acting torque wrench (24), to permit subsequent advances of the wrench (24) within the post-advan ce period without restarting the pump (16) or to permit a single acting wrench to be moved from one fastener to the next within the po st- advance period without restarting the pump (16). Operation of the pump (16) is terminated when the post-advance period expires if the advance actuator (55) is not reactuated, so as to conserve energy and avoid unnecessary heating of the hydraulic fluid.

Title: Portfolio structuring using low-discrepancy deterministic sequences
Inventor: TRAUB JOSEPH F
IPC: G06Q40/00
Filed: 1999-08-18
Granted: 2003-01-21
Abstract: In securities valuation, in setting the initial offering price of a financial instrument, or in later revaluation as financial parameters such as interest rates may change, an estimate of the value of the instrument may be represented as a multi-dimensional integral. For evaluation of the integral, numerical integration is preferred with the integrand being sampled at deterministic points having a low-discrepancy property. The technique produces approximate values at significant computational savings and with greater reliability as compared with the Monte Carlo technique. Further to estimating the value of a complex security, sampling at points of a low-discrepancy deterministic sequence can be used in estimating value at risk in portfolio structuring.

Abstract: L'invention concerne un dispositif de balayage lumineux destiné à l'excitation et à la détection de lumière secondaire, notamment de lumière fluorescente, sur un échantillon, comportant un dispositif émetteur de lumière pour émettre de la lumière d'excitation présentant une longueur d'onde appropriée pour exciter de la lumière secondaire sur ou dans ledit échantillon, une unité de balayage pour balayer au moins une surface partielle de l'échantillon avec la lumière d'excitation, et une unité de détection de la lumière secondaire émise lors de l'excitation de l'échantillon, comprenant une optique de détection et un détecteur. Lors de l'utilisation de détecteurs ponctuels ne permettant pas une résolution élevée, le détecteur doit être lu et ré-initialisé à chaque fois qu'un point de balayage sur l'échantillon a été éclairé, ce qui nécessite un temps d'attente avant de pouvoir refocaliser le faisceau de balayage. Pour éviter cet inconvénient et accroître la vitesse de lecture et en même temps améliorer la résolution locale sur l'échantillon, le dispositif décrit utilise un dispositif détecteur avec une pluralité d'éléments détecteurs positionnés dans un champ à des coordonnées locales prédéterminées. Ces éléments détecteurs placés dans un plan d'imagerie de l'optique de détection convertissent en signaux électriques la lumière détectée avec une haute résolution.

The apparatus includes a mechanism for determining whether the pressure of the fluid in the pipe has negatively deviated from an expected pressure-temperature relationship of the fluid in the pipe. A method for detecting a fluid leak in an isolated segment of a pipe: The method consists of five steps: Step 1, measure the average propagation velocity of the fluid in an isolated segment of the pipeline at time t1. Step 2, measure the pressure of the fluid in the isolated segment of the pipe at time t1. Step 3, measure the pressure of the fluid in the isolated segment of the pipe at time t2 and calculate the change in pressure occurring between t2 and t1. Step 4, measure the average propagation velocity of the fluid in an isolated segment of the pipe at time t2 and determine the corresponding change in average temperature. Step 5, calculate the amount of pressure change due to temperature changes and the amount due to probable leaks.

Abstract: A phase-modulated signal such as a quadrature phase-shift-keyed (QPSK) signal in a wireless communication system is demodulated using sample timing based at least in part on frequency information generated by frequency demodulating the phase-modulated signal. The phase-modulated signal is separated into first and second portions, the first portion is phase demodulated to generate demodulated symbols, and the second portion is frequency demodulated to generate, e.g., a measure of the instantaneous frequency of the phase-modulated signal. The instantaneous frequency measure is processed to identify one or more symbol transitions, and the identified transitions are used to establish the sample timing such that proper sampling of the symbols is ensured.

Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source, and an orifice ring forming a second orifice vertically spaced beneath and aligned with the first orifice. A chamber surrounds the second orifice and communicates with the second orifice through a metering gap between the first and second orifices. Casing glass is delivered from a second source to the chamber, such that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. A heater ring of refractory material is disposed beneath the orifice ring, and includes at least one electrical heater embedded in the refractory material of the heater ring. The electrical heater is thus disposed external to the casing glass chamber for adding heat to casing glass flowing through the chamber to the metering gap. The heater ring in the preferred embodiment of the invention underlies and is contoured for facing engagement with the entire undersurface of the orifice ring for transferring heat energy through the orifice ring to glass in the casing glass chamber.
