Title: Monitoring of a fluid in an open channel
Inventor: MICHAEL AINGER
IPC: G01P5/26
Filed: 2016-07-28
Abstract: A method of monitoring fluid flow in an open channel 2 using a sensing optical fiber 10 extending along the channel below the surface of the fluid 4. The method comprises sending light pulses into the sensor optical fibre, receiving backscattered light from the sensor optical fibre, and analysing properties of the backscattered light to obtain data relating to strain along the sensor optical fibre. The strain data may be processed to derive information about fluid flow parameters such as fluid depth, flow velocity and flow volume. There may be a plurality of measuring points along the length of the sensor optical fibre. A temperature in the conduit may be measured and used to compensate the measured strain. The Rayleigh backscattered light may be analysed using optical time domain reflectometry (OTDR) or optical frequency domain reflectometry (OFDR). The fibre may be protected by a containment system that converts the fluid pressure to a strain in the fibre and that thermally insulates the fibre. The method is utilized in flows with a free surface such as sewers, rivers, drains, culverts and levees.

Title: Magnitude compensation technique for processing single-bit wide data
Inventor: DYLAN A HESTER
IPC: H03M1/66
Filed: 2016-06-21
Abstract: Droop caused by a filter may be compensated by applying a pre-filter to the audio signal that cancels out, at least in part, the droop caused by the filter. The pre-filter may implement magnitude compensation that causes an approximately flat passband response when the pre-filtered signal is passed through the filter. The pre-filter may be applied to one-bit wide data streams, such as high-fidelity direct stream digital (DSD) audio data or other one-bit wide data such as pulse-density modulation (PDM) encoded data. The pre-filtering and filtering may be implemented in components of an audio processor, such as in a digital-to-analog converter (DAC). The pre-filtering may include upsampling the one-bit wide data to form symbols and substituting an eighth bit of the symbol with an inverted version of an earlier-received bit.
