Abstract: A system and method are for detecting and identifying underground tunnels by using: (i) bentonite-slurry for filling at least one essentially-vertical moat along a desired borderline, (ii) at least one detection device associated with the moat(s); and (iii) at least one control system connected to all detection devices.

Abstract: The present invention provides a system and method for detecting underground tunnels by using bentonite-slurry.

Abstract: A system and method for pressure locking a downhole tool in position during a drilling operation includes rotating the drill string to drill a borehole. A fluid is pumped through a passage of a drill string in the downhole direction wherein fluid undergoes a pressure drop at the downhole end of the drill string such that fluid in the passage of the drill string is under higher pressure than the fluid outside the drill string. While fluid is flowing, an uphole portion of the downhole tool, such as a MWD tool, is exposed to the higher pressure fluid and a downhole portion of the downhole tool to the lower pressure fluid, thereby seating the downhole tool in a receptacle member attached to the drill string in the passage. Ceasing flow easily eliminates the locking force created by differential pressure allowing the tool to be retrieved.

Abstract: A universal pot cover holder with spoon rest is an apparatus capable of placing hot dripping pot covers without having them on the counter top. A unit that sits the pot cover upright and also can accommodate up to two pot covers at same time and two stirring spoons. A unit that will bring organization around the stove, eliminate counter mess, accommodates any pot cover with any knob or handle. Unit is one continuous welded apparatus with the exception of a removable glass bowl.

Abstract: The subject matter discloses a computerized method for real time emotion detection in audio interactions comprising: receiving at a computer server a portion of an audio interaction between a customer and an organization representative, the portion of the audio interaction comprises a speech signal; extracting feature vectors from the speech signal; obtaining a statistical model; producing adapted statistical data by adapting the statistical model according to the speech signal using the feature vectors extracted from the speech signal; obtaining an emotion classification model; and producing an emotion score based on the adapted statistical data and the emotion classification model, said emotion score represents the probability that the speaker that produced the speech signal is in an emotional state.

Abstract: A torch wire feeder which includes a planetary feeder, an electrical motor and a handle. The feeder is characterized in that the electrical motor along with the planetary head is mounted to a back holder, and the goose-neck is mounted to a front holder, as the front and the back holders are assembled with the tubes for water-cooled and gas-cooled operation, as the back holder receives the wire from the conduit with holder thread nut. Furthermore, water tubes and a gas tube from the conduit are assembled to the back holder with a nut, and the front holder has distributor holes for gas and water cooling and also thread nut for transmitting the welding current, the water and the gas from the conduit to the neck, also contacting the holder to the thread nut with rubber seal, as all the parts are assembled to the handle with ergonomic form and also containing two potentiometers and start-stop switch and the hook, a all details and parts are included in ergonomic form body.

Abstract: A universal planetary feeder for feeding a wire which includes an elongate hollow body defining a wire feed axis and adapted for high speed rotation about the axis, and a pair of planetary rollers associated with the body so as to be rotatable together with the body about the feed axis and which are mounted about the feed axis in mutually skewed respective orientations. The planetary rollers define circumferential peripheral feed surfaces spaced from each other about the feed axis and are configured for simultaneous engagements with a wire along preselected lines of contact. Each of the feed surfaces is intersected at right angles by a plane which is offset from the feed axis by an offset angle.
