Abstract: Device and method for locating leaks in pipelines, overhearing even weak sounds, from leaking fluid especially in pipelines made of material with limited sound conductivity such as plastic. The device includes a first thin diaphragm (1) with one side (3) in contact with the fluid, whereby vibrations are transferred from the fluid to a second diaphragm (5) joined to the opposite side of the first diaphragm (1).   The second diaphragm (5) is made of a preferably sound-sensitive piezo-electrical plastic-foil, the diaphragms being able to co-vibrate with frequencies from one to a few thousand Hertz. The first diaphragm (1) protects against the inner pressure in the liquid lint and moderates any sympathetic vibration.   The low-frequency A.C. that is generated by the vibration in the second diaphragm (5) is amplified and transposed to a range of frequencies that is audible for the human ear.

Abstract: A reverse wiring indicator for a GFCI receptacle alerts the installer in the event that the AC source has been improperly wired to the load or feedthrough terminals of the receptacle rather than to the source or input terminals. The reverse wiring indicator operates by open-circuiting one of the load or feedthrough terminals of the receptacle, and may take the form of a removable barrier which inhibits conduction through one of the power contact sets of the GFCI circuit breaker until the receptacle has been installed and successfully tested. The contact set through which conduction is inhibited is the one other than that to which the TEST switch is connected, and the other contact set is allowed to conduct in the normal manner.      The removable barrier prevents a current path from being established through the load or feedthrough terminals of the receptacle in the event that the receptacle has been miswired, thereby preventing the TEST switch from falsely tripping the circuit breaker in that situation, but does not prevent the TEST switch from operating normally to trip the circuit breaker if the receptacle has been properly wired. The removable barrier may be provided in the form of a thin strip of electrically insulating material (such as Mylar tape] which is held between one set of closed power contacts and protrudes through the front of the receptacle housing so that it is conspicuous and easily removable.

Abstract: A method for the rapid estimation of hyperplastic and hypertropic changes in animal airways is an assay which specifically measures acidic and neutral mucoproteins in a linear fashion from 0.5 µg to at least 10 µg. The assay comprises exposure of a test animal to a suspected metaplastic inducer, removal of the lungs, homogenization in an appropriately buffered solution containing reducing agents and protease inhibitors removal of particulate matter, and size-fractionation of the SDS treated soluble extract. The high molecular weight material is immobilized and stained for either acidic or neutral mucosubstances and the specific staining is quantitated. The changes observed are consistent with those seen in histological sections of the exposed tissues. The assay is useful in confirming the metaplastic potential of suspected compounds, in determining what neurohumoral mediator(s) are involved in mucus cell metaplasia in animal models for chronic obstructive pulmonary disease, and in identifying compounds which might ameliorate these effects.

Title: High gain acoustic transducer
Inventor: FENNER THOMAS CLARK JR
IPC: H04R7/12
Filed: 1994-11-23
Granted: 2005-02-08
Abstract: A high gain acoustic transducer is formed of a voice coil and a magnetic material housed within a transducer housing. The transducer housing includes two symmetrical dome halves formed of a flexible material. Vibrations of the transducer induce a current in the voice coil as the magnetic material is caused to translate relative to the voice coil. Alternatively, electrical signals applied to the voice coil induce vibrations in the transducer. The voice coil is supported by a first of the two dome halves by way of a first support assembly, and the magnetic material is supported by a second of the two dome halves by way of a second support assembly. The first and second support assemblies are positioned against similarly- dimensioned portions of the first and second dome halves, respectively. Resonating surfaces of the two dome halves are of substantially similar dimensions. The housing forms a watertight enclosure, and the transducer may be utilized in underwater applications.

Abstract: A personal computer (PC) incorporates a speaker/microphone peripheral, which includes a digital-signal-processor (DSP) based acoustic echo canceler and supports a plurality of modes of operation. One mode is a video/telecommunications mode. In this mode, the acoustic echo canceler is enabled and the speaker/microphone peripheral provides a monaural dual speaker and microphone for use in video, internet telephony, etc., communications. Another mode of operation is a multi-media, or wide-band stereo, mode. In this multi-media mode, the acoustic echo canceler is disabled and the stereo loudspeakers provides high fidelity stereo output signals. In addition, in this latter arrangement an optional sub-woofer may be additionally coupled to the stereo loudspeakers. The speaker/microphone peripheral switches between the operating modes by detecting a predefined sequence of dual-tone-multi-frequency (DTMF) digits. The DTMF sequences are played from wave-type files stored on the PC.
