Title: Audience survey system, and systems and methods for compressing and correlating audio signals
Inventor: KENYON STEPHEN C
IPC: G10L19/00
Filed: 2000-06-16
Abstract: A system and method are disclosed for performing audience surveys of broadcast audio from radio and television (1). A small body-worn portable collection unit (4) samples the audio environment of the survey member (5) and stores highly compressed features of the audio programming. A central computer (7) simultaneously collects the autio outputs from a number of radio and television receivers (6) representing the possible selection that a survey member may choose. On a regular schedule the central computer (7) interrogates the portable units (4) used in the survey and transfers the captured audio feature samples. The central computer (7) then applies a feature pattern recognition technique to identify which radio or television station the survey member (5) was listening to at various times of day. This information is then used to estimate the popularity of the various broadcast stations.

Title: Adjustable length handle for flat finishers
Inventor: MACMILLAN DONALD M
IPC: B25G1/04
Filed: 2002-03-05
Abstract: The primary structural parts of the handle are two telescopic tubes, the smaller diameter tube being an extrusion. A rib on the smaller tube engages a notch in a fitting attached to the larger tube to prevent relative rotation of the tubes. A box footplate is pivotally attached to the free end of the larger tube, the axis of the pivot being perpendicular to the axis of the tubes. The footplate is connected by a connecting link to the end of a tube which slides longitudinally in the handle and fits through a clamp mechanism installed in the overlapped end of the smaller tube and is operated by a clamp mechanism operating assembly attached to the free end of the smaller tube.  Operating a lever of that assembly engages the tube in the lock mechanism, preventing it from moving longitudinally and the footplate from pivoting on the handle. The length of the handle is manually adjustable and is set at a desired length by a lever operated lock assembly attached to the overlapped end of the larger tube.

Title: Means and apparatus for control of remote electrical devices
Inventor: FOSTER MICHAEL B
IPC: G05B19/00
Filed: 2000-06-30
Abstract: An apparatus to control remote devices or equipment via existing cellular telephone networks.      The apparatus receives information from a customer concerning a specific function, which the customer wants to perform at the remote equipment. A Central Control receives this information from the customer and correlates the function to a specific cellular telephone MIN number, which has been pre-programmed in a computer at the Central Control. The MIN number is then sent to a cellular provider. The cellular provider then transmits the MIN number to an antenna, which transmits the MIN number to a remote equipment controller at the remotely located equipment. The remote equipment controller then takes a part of the MIN and gives these numbers to a PLC at the remote equipment controller. The PLC then memory maps the part of the MIN to a specific function to be carried out by the remote equipment controller. Then the remote equipment controller carries out specified functions at the remote equipment.

Title: Self-terminating electrical connector
Inventor: PFIEFER DALE
IPC: H01R13/646
Filed: 2000-09-22
Abstract: The present invention relates to electrical connectors, and in particular to an electrical connector providing a means for establishing an automatic grounded termination point for the connector upon disconnection of the connector from an external signal source or receiving device. In the absence of an external electrical connection, the connector will be configured to establishing an automatic grounded termination point to eliminate the effects of stray capacitances, spurious extraneous signals and signal reflections on the circuitry connected to conductor. When coupled to an external connector, the connector ground connection will be broken to permit establishing a signal path for external circuitry. Also, a capacitive material can optionally be placed in series with the grounding resistive element assembly to block direct current to the resistive element in its grounded state that would otherwise overheat and damage the electrical resistor material.

Title: Procede et dispositif d'injection double de carburant dans un moteur a combustion interne
Inventor: ANCIMER RICHARD
IPC: F02D19/10
Filed: 2001-02-09
Abstract: Selon l'invention, deux carburants différents sont injectés dans la chambre de combustion d'un moteur à combustion interne. Un carburant principal est allumé par un carburant pilote ayant un pouvoir d'auto-allumage supérieur au carburant principal. Selon ce procédé, des conditions de charge sur le moteur sont contrôlées et des ensembles de conditions sont définies afin de constituer des conditions de charge faible et des conditions de charge élevée. Des modes de fonctionnement distincts sont définis pour chaque ensemble de conditions de charge. Sous des conditions de charge faible, un mélange homogène d'air et de carburant principal est trop pauvre pour assurer une combustion stable, par conséquent, le carburant principal est injecté sous haute pression immédiatement après injection du carburant pilote. Sous des conditions de charge élevée, le carburant est injecté en trois étapes. Dans la première étape, le carburant principal est mélangé à de l'air d'admission avant introduction dans la chambre de combustion, ou le carburant principal est injecté durant l'admission ou au début de l'admission.

Title: Method of determining resistivity and/or dielectric values of an earth formation as a function of position within the earth formation
Inventor: HAUGLAND SAMUEL MARK
IPC: G01V3/28
Filed: 2003-02-28
Abstract: A technique of estimating electrical parameters of an earth formation accounts for spatial inhomogeneities and frequency dispersion. The results are achieved using a model which is evaluated to generate predicted values for a plurality of electrical signals measured in a borehole in an earth formation as a function of a first set of model electrical parameters, a second set of model electrical parameters and model spatial coordinates of boundaries between regions of the earth formation. Transformations are applied to the measured electrical signals and the predicted values. The electrical parameters and spatial coordinates are selected to cause approximate agreement between the transformed measurements and the transformed predicted values. In some embodiments, the first set of electrical parameters is a set of conductivity values; the second set of electrical parameters is a set of dielectric constant values; and the spatial coordinates define regions of the earth formation where different values for the conductivity and dielectric constant apply.
