Publication number: 20140016791Abstract: Loudness control systems or methods may normalize audio signals to a predetermined loudness level. If the audio signal includes moderate background noise, then the background noise may also be normalized to the target loudness level. Noise signals may be detected using content-versus-noise classification, and a loudness control system or method may be adjusted based on the detection of noise. Noise signals may be detected by signal analysis in the frequency domain or in the time domain. Loudness control systems may also produce undesirable audio effects when content shifts from a high overall loudness level to a lower overall loudness level. Such loudness drops may be detected, and the loudness control system may be adjusted to minimize the undesirable effects during the transition between loudness levels.Type: ApplicationFiled: March 15, 2013Publication date: January 16, 2014Applicant: DTS, Inc.Inventors: Brandon Smith, Aaron Warner, Jeff Thompson

Publication number: 20130182852Abstract: There is disclosed methods and apparatus for decomposing a signal having a plurality of channels into direct and diffuse components. The correlation coefficient between each pair of signals from the plurality of signals may be estimated. A linear system of equations relating the estimated correlation coefficients and direct energy fractions of each of the plurality of channels may be constructed. The linear system may be solved to estimate the direct energy fractions. A direct component output signal and a diffuse component output signal may be generated based in part on the direct energy fractions.Type: ApplicationFiled: September 12, 2012Publication date: July 18, 2013Inventors: Jeff Thompson, Brandon Smith, Aaron Warner, Zoran Fejzo, Jean-Mar Jot

Publication number: 20130161545Abstract: An electromagnetic valve for use in controlling fluid flow between first and second passageways in a hydraulic valve block includes a valve body. The valve body defines a central axis, has a central opening therethrough, and has a lower end adapted to be inserted into a bore of the valve block. A hollow valve dome is attached to an upper end of the valve body. An armature is axially moveable within the valve dome. A spring biases the armature in one axial direction. A closing element is coupled to a lower end of the armature. An electromagnetic coil coaxially surrounds the armature and is operable to effect axial movement of the armature in an axial direction opposite the one axial direction. A valve seat member is carried by a lower end of the valve body and has an orifice providing fluid flow between the first and second valve block passageways. The valve seat member defines a valve seat that surrounds the orifice and cooperates with the closing element for selectively closing the orifice.Type: ApplicationFiled: February 3, 2011Publication date: June 27, 2013Applicant: KELSEY-HAYES COMPANYInventors: Leon Leventhal, Peter J.

Publication number: 20120005884Abstract: Provided herein are methods, apparatuses and systems for fabricating photovoltaic cells and modules. In certain embodiments, the methods, apparatuses and systems involve coating ferromagnetic substrates with thin film solar cell materials and using magnetic force to constrain, move or otherwise manipulate partially fabricated cells or modules. According to various embodiments, the methods, apparatuses and systems provide magnetically actuated handling throughout a photovoltaic cell or module fabrication process, from forming photovoltaic cell layers on a substrate to packaging the module for transport and installation. The magnetically manipulated processing provides advantages over conventional photovoltaic module processing operations, including fewer mechanical components, greater control over placement and tolerances, and ease of handling.

Patent number: 8058874Abstract: A system for detecting a buried conductor comprises a transmitter for producing an alternating test current in the buried conductor and a receiver for detecting an electromagnetic field produced by the test current in the buried conductor. A communication link is provided between the receiver and the transmitter. The receiver measures the signal to noise ratio, SNR, of the electromagnetic field produced by the test current and if the SNR is below a threshold then the receiver controls the transmitter to set frequency and/or power characteristics of the test current.Type: GrantFiled: March 2, 2009Date of Patent: November 15, 2011Assignee: Radiodetection LimitedInventors: John Mark Royle, Jeff Thompson

Patent number: 7403012Abstract: A detector for detecting a buried current carrying conductor includes a digital signal processor, magnetic sensors, and a power supply unit. The power supply unit is a switched mode power supply which incorporates a proportional integral differential controller feedback algorithm and which is managed by the digital signal processor. The load and source voltage are monitored by the digital signal processor and a look-up table is used to control a pulse width modulator, which drives a single ended primary induction controller. The digital signal processor processes and compares signals received from the sensors to calculate a depth of a buried conductor. The self-generated noise of the power supply unit does not interfere with the frequency bands of detection of the detector.Type: GrantFiled: June 20, 2006Date of Patent: July 22, 2008Inventors: Robert Worsley, Jeff Thompson, Richard Pearson, Mark Royle

Patent number: 7339379Abstract: A detector 1 for detecting a current carrying conductor has a pair of vertically spaced antennae 3, 5 to detect the magnetic radiation produced by a current carrying conductor as a result of one or both of the mains power supply or an electromagnetic signal which is induced in the conductor by a dedicated signal transmitter. The detector 1 continuously calculates the depth of a buried conductor and if the buried conductor is above a predetermined minimum depth then the detector 1 triggers an audio and/or visual alarm. By reducing the sensitivity of the antennae 3, 5, the lateral offset range for which the alarm sounds is reduced and the location of a buried conductor can be determined.Type: GrantFiled: June 20, 2006Date of Patent: March 4, 2008Assignee: Radiodetection LimitedInventors: Jeff Thompson, Richard Pearson, Robert White
