Abstract: Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor.

Abstract: Techniques of rendering sound for a listener involve determining, at a first position, a set of directions from which some specified fraction of the sound field energy originates and reconstruct the sound field at a second position based on the set of directions. Along these lines, a sound rendering computer may receive sound data representing sound emanating from positions on a sphere centered on a microphone. Nevertheless, only a small fraction of these points on the sphere contribute much of the sound field energy directed at the listener. The sound rendering computer determines such directions using a directional decomposition in which those directions having the highest fraction of the sound energy are identified. When the listener moves away from the microphone's position, the sound rendering computer, after identifying such directions, applies an amplitude and phase factor to the sound fields corresponding to those directions.

Abstract: Flow sensors are provided that can monitor flow conditions. The flow sensor includes a gauge that provides a first level of information about flow through the sensor, and an indicator associated with the gauge that can provided a second level of information about flow through the sensor. The indicator might be in the form of a dial that can rotate about the gauge and might include a locked position for monitoring flow and an unlocked position to rotate the dial about the gauge to reposition the dial. A twisted shaft with varying twist rate is provided to convert linear motion to rotational motion for the gauge.

Abstract: The present invention makes use of a modular Folded Tubular Photometer to measure the concentrations of gas-phase species and/or particles, including especially air pollutants such as ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and black carbon particulate matter, by means of absorbance of ultraviolet (UV), visible or infrared (IR) light. The optical bench makes use of modular components (tubes and mirror assemblies) that allow construction of path lengths of up to 2 meters or more while maintaining low detection cell volumes. The long path lengths, low cell volumes, and the innovation of pressure equalization during the absorbance measurements enable sensitive detection of ambient air pollutants down to low part-per-billion levels or less for gas species, and extinctions down to 1 Mm?1 or less for particulate matter, corresponding to ˜0.13 ?g/m3 or less for black carbon particulates.

Abstract: A method of encoding sound objects includes receiving a set of monophonic sound inputs. Each of the set of monophonic sound inputs includes position and orientation information of a sound object relative to a source position. The set of monophonic sound inputs are encoded into a higher order ambisonic (HOA) sound field in a spherical harmonics domain based on a spherical harmonics dataset including a subset of all spherical harmonic coefficients for a given subset of azimuth and elevation angles. Some embodiments include decoding the HOA sound field to generate a set of loudspeaker signals.

Abstract: A computing device includes a processor and a memory. The processor is configured to generate spectrograms, for example, using short-time Fourier transform, for a plurality of channels of reference and test ambisonic signals. In some implementations, the test ambisonic signal may be generated by decoding an encoded version of the reference ambisonic signal. The processor is further configured to compare, for each of the plurality of channels of a reference ambisonic signal, at least a patch associated with a channel of the reference ambisonic signal with at least a corresponding patch of a corresponding channel of the test ambisonic signal and determine a localization accuracy of the test ambisonic signal based on the comparison. In some implementations, the comparing may be based on phaseograms of the reference and test ambisonic signals.

The method includes sending a request for the transfer of control of the collaborative session in response to the received request to a second UE, and receiving, in response to the sent request to the second UE, an indication of acceptance of the transfer of control of the collaborative session. The method includes sending a notification of status to the first UE of the control of the collaborative session in response to receiving, from the second UE, the indication of acceptance.

Abstract: Techniques of performing binaural rendering involve combining left and right HRTFs from speakers symmetrically placed with respect to a forward axis of a listener's head. Because of the symmetry of the listening geometry, a decoded loudspeaker signal resulting from each speaker may be decomposed into symmetric and antisymmetric components according to whether a spherical harmonic associated with a respective ambisonic channel is symmetric or antisymmetric about the forward axis. The result involves rendering the left and right headphone speakers using the same sum and difference HRTFs rather than a different pair of HRFTs for each headphone speaker.
