Abstract: A handheld ultrasound detection apparatus includes a portable housing with a flexible tube that extends from the housing and includes a sound cup and an ultrasound receiver for converting received ultrasound energy into an electronic signal. A gain/active filter includes four amplifiers each having an associated gain range. The apparatus is programmed based on a size of the electronic signal, to direct the electronic signal along a linear scale through one or more amplifiers and apply an appropriate gain to the signal, and to generate a percentage value corresponding to the gain and with respect to the linear scale. In a manual mode, data is generated corresponding to a particular gain range and a percentage value from 0-100% with respect to the particular gain range, while during an automatic mode data is generated corresponding to a percentage value from 0-400% with respect to a collective gain range.

Abstract: A handheld ultrasound detection apparatus of the present disclosure has a housing comprising a display device and a flexible tube attached at its distal end to the housing, the flexible tube housing an ultrasound receiver for receiving ultrasound energy and converting the ultrasound energy into an electronic signal. The handheld ultrasound detection apparatus further has logic configured to receive the electronic signal and convert the electronic signal to digital data, the logic further configured to display data indicative of the digital data to the display device.

Abstract: A leak detection apparatus has a transducer arranged for detection of sound, the transducer translating the sound into an analog signal and a display device. In addition, the leak detection apparatus has logic configured to detect the analog signal and display to the display device a gain range corresponding to the signal.
