Abstract: An apparatus and method to determine a position of a mobile wireless transceiver. The invention merges GPS position location and wireless communication technologies to achieve a precise position location i n dense urban and other environments when line-of-sight to the satellites is somewhat obscured. The inventive apparatus and method use signals from only two GPS satellites (60, 70, 80, 90) and the serving terrestrial base station. In a most general sense, the inventive method includes the steps of receiving at a base station (10) a first signal transmitted from a first GPS satellite and a second signal transmitte d from a second GPS satellite. The mobile's transmitter (200) and receiver (100) are adapted to receive these GPS signals as well and transmit a third signal to the base station in response thereto. The base station (10) receives the third signal and uses it to calculate the position of the wireless unit (20).

Abstract: A gas cooking appliance, having burner units mounted on an upper cooktop and an oven cavity arranged below the burner units, incorporates a fan for generating a flow of cooling air within the appliance, with the cooling air extending along an at least back and top wall portion of the oven cavity. The cooling air exists the appliance through a frontal gap formed between a door of the oven cavity and an upper frontal portion of the appliance. The burner units have associated combustion air inlets which are isolated from the flow of cooling air by being disposed in a chamber formed by sealing an isolation pan beneath the cooktop. The cooktop is formed with a plurality of openings for permitting a flow of combustion air to be drawn into the chamber for mixing with a regulated flow of combustion gas. With this arrangement, the gas burner units are isolated from the flow of cooling air within the appliance to enhance the operation of the burner units, particularly during low or simmer settings.

Title: Abnormalities detection with acoustic monitor
Inventor: RADOMSKI JAMES V
IPC: G01M99/00
Filed: 1999-07-14
Granted: 2007-05-22
Abstract: Monitor for detecting abnormalities and thus determining the operating condition thereof by continuously computing the power spectrum of the monitored sound and has two modes of operation: learn and operate. The monitor is placed in the learn mode during a time when the machine or process to be monitored is known to be operating normally. During the learn mode, the maximum and minimum acoustic power output from each of a plurality of digital bandpass filters is continuously maintained and updated in data memory as the acoustic signature of the machine or process being monitored. During the operate mode, the monitor continuously compares the real-time filter outputs with the acoustic signature stored during the learn mode and activates a panel lamp and relay if the output of any of the bandpass filters deviates from the upper or lower decibel limits of the acoustic signature by more than the setting of the corresponding front panel sensitivity selector switch. Two alarm levels are provided by the monitor: warning, to indicate a developing fault, and danger, to indicate a situation requiring immediate corrective action.

Abstract: L'invention se rapporte à un processus et à un système de récupération par pyrolyse de constituants souhaitables à partir de morceaux de pneus de véhicules. Ledit système inclut une section de pyrolyse qui est divisée en une pluralité de zones de chauffage individuelles. Chacune des zones de chauffage est amenée à une température de fonctionnement distincte qui est indépendante de la température de fonctionnement des autres zones de chauffage. Des morceaux de pneus de véhicules sont introduits dans la section de pyrolyse au niveau de son extrémité d'alimentation par un cylindre d'alimentation rotatif qui possède un filet de type vis en saillie à partir de la paroi interne du cylindre d'alimentation. Lorsque le cylindre d'alimentation tourne, le filet dirige les morceaux de pneus en entrée vers l'extrémité d'alimentation de la section de pyrolyse. La section de pyrolyse comprend un four tournant qui est divisé en une pluralité de zones de chauffage. Les morceaux de pneus sont acheminés à travers la pluralité des zones de chauffage du four tournant, de son extrémité d'alimentation vers son extrémité d'évacuation, de sorte que les morceaux subissent une pyrolyse lorsqu'ils traversent ce four tournant. Un trommel rotatif, qui est couplé à l'extrémité d'évacuation du four tournant, est conçu pour décomposer les morceaux de pneus pyrolysés en leurs constituants souhaitables.

Title: Method of determining the salt content of liquids and device for practicing the method
Inventor: OHM KLAUS
IPC: G01N33/18
Filed: 2000-04-26
Granted: 2008-12-02
Abstract: Known methods use the temperature of the water bath which surrounds the liquid sample as the adjusting parameter. The aim in these methods is to maintain the water bath at a constant temperature in order to fulfill the prerequisites for calibration.  In contrast, in the inventive method a measurement is determined for the maximum permissible drift (.alpha.max) in the temperature of the water bath ('B) which is measured as the equivalent of the sample temperature ('P). This greatly simplifies the problem of adjusting the temperature which primarily arises as a result of the delays in the control circuit. The adjusting element need only recognize a drift (.alpha.) and correct the sum of the thermal currents which have occurred, to zero, allowing for a residual error (P restmax) which results from a permissible contouring error ('B, 'P).  The release of heat from the mixing propeller (Q) is used to obtain a rapid compensation. In addition, a number of improvements have been made to the construction of a device for carrying out the inventive method. Overall, said inventive method results in much more accurate measurement results. The method and device can be used in all fields in which the determination of the salt content of liquids is of interest, for example, in oceanography and in this particular field, in polar research.

Granted: 2010-04-06
Abstract: A quick connecting universal electrical box system for the mounting of electrical sockets, switches or any electronic or communication component that is typically installed into a wall is disclosed. The system comprises a mounting frame and an electrical box, which can be pre-wired with any socket unit or component, such that installation of the electrical box into a wall is greatly simplified. The mounting frame is first inserted into a wall, followed by insertion of the electrical box into the mounting frame. The action of inserting the electrical box into the mounting frame forces flaps in the mounting frame to engage and lock the mounting frame into the wall. Retaining studs formed on flexible side panels of the electrical box then engage with corresponding openings in the mounting frame to secure the electrical box within the mounting frame. Secure installation of this electrical box is simple and quick without the need for any tools or fastening screws.
