Fermentation product monitoring systems and associated methods. A fermentation product monitoring system comprises an ultrasonic transmitter configured to transmit a transmitted ultrasonic signal through a fluid; an ultrasonic receiver configured to receive a received ultrasonic signal; an automated valve configured to regulate a flow of the fluid; and a signal generation and analysis assembly configured to actuate the automated valve responsive to detecting a transition from a first fluid comprising a slurry to a second fluid comprising a non-slurry. A method of using a fermentation product monitoring system comprises transmitting a transmitted ultrasonic signal through a fluid; receiving a received ultrasonic signal; processing a received electrical signal; and actuating an automated valve to regulate a flow of the fluid responsive to a detecting that the fluid within the primary ultrasonic signal path has transitioned from a first fluid comprising a slurry to a second fluid comprising a non-slurry.

Provided are acoustic quick response codes and piezoelectric quick response (PQR) codes. Examples of the disclosure leverage acoustics and vibrations for information storage and retrieval. Applications of examples of the disclosure may include the development of embedded product tags, tamper-evident seals and/or tags, and/or an additional layer of information storage used in conjunction with other existing information storage technologies. Examples further provide for the use of acoustic quick response codes or piezoelectric quick response codes as embedded sensors for damage detection and/or monitoring.

Piezoelectric and acoustic quick response codes

A method of and system for producing a Bessel-like collimated sound beam frequencies below 1 MHz, and a device for sound (acoustic) imaging. A flat disk piezoelectric transducer having a large diameter/thickness ratio may be configured to exhibit radial vibration modes in the desired frequency range according to one or more parameters, including the diameter/thickness ratio, materials, electrode coverage, etc. The transducer may be driven by a waveform generator at one or more radial mode excitation frequencies.

Simple bessel-like collimated sound beam generator

A multi-frequency signal may be used to induce voltage difference across a portion of a pipe. The voltage difference may be induced to take multi-frequency measurement of impedance characteristics of fluid inside the pipe. The multi-frequency measurement of the impedance characteristic of the fluid inside the pipe may be used to determine a characteristic of the fluid inside the pipe. This may be achieved by active integration of experimental data with high-resolution multi-frequency electrical impedance tomography (MFEIT) modeling.

Characterization of fluid inside pipe using multi frequency electrical signal

Apparatus includes a plurality of geological subsurface electrical line sensors spaced apart from each other proximate a predetermined geological subsurface region of interest, with at least one of the electrical line sensors situated as a line source to produce a multi-frequency electrical impedance tomography source signal, and with at least one of the electrical line sensors situated as a line detector to receive the multi-frequency electrical impedance tomography response signal associated with the source signal that propagates through the predetermined geological subsurface region of interest, and a controller including a processor and a memory configured with instructions that, when executed by the processor, cause the processor to determine an electrical mapping over the predetermined geological subsurface region of interest based on the multi-frequency electrical impedance tomography source signal, response signal, and the spatial positions of the geological subsurface electrical line sensors.
