  • Patent number: 9200979
    Abstract: The present invention is directed an ultrasonic frequencies fault detecting apparatus. The present invention uses high frequency ultrasonic energy signals to analyze bearings and determine the presence of faults therein. The ultrasonic return signals are heterodyned (by amplitude demodulation) into the audio spectrum for purposes of audio detection. In addition, a FFT spectrum of the signal is displayed on a monitor for more accurate results. According to the present invention software is used to automatically analyze the FFT spectrum by comparing the current spectrum with stored spectrums of known bearing conditions as modified based on the rotary speed of the bearing and the number of balls. Once a defect in a bearing has been located in this manner using automated FFT analysis, an operator can then use a device, such as a calibrated lubricant dispenser, to effectuate maintenance and/or repair.

Such monitoring is particularly useful for both diagnosing and prescribing preventive medical treatment, and is particularly suited for the field of cardiovascular health care. Preferred methods and devices include using a sensitive acoustic device, such as an electret, to analyze a patient's cardiovascular functions from a location such as a public computer kiosk, a doctor's office or a patient's home computer. The data may be downloaded from the acoustic device to a central database located, for example, on the Internet. The data may be retrieved by the patient, or upon instructions from the patient, may be transferred to or accessed by doctors for purposes of diagnosis, monitoring and treatment.

  • Publication number: 20060029199
    Abstract: A system provides messages from deceased relatives and friends, which messages are readily accessible. Before death a person records various messages for loved ones. The system stores these messages at a location and associates PIN numbers with each individual for whom there is a message. Either the intended recipient is given information about the message or leaving of a message by a symbol located in a conspicuous place, e.g., on the headstone of the deceased. The person then calls a 900 number or logs onto a specific website. In response to the correct answers to certain questions, the intended recipient is given their PIN. Using the PIN, the person can contact the system and received the recorded message at any time, e.g., by cell phone at the grave site. Alternatively, the grave site itself can be wired to provide the message, e.g., from a tape recorder over headphones or at special kiosks at the cemetery.

  • Patent number: 6996030
    Abstract: A focal point reflector is used in conjunction with a dual heterodyne circuit to reduce reception nulls that can occur when performing ultrasonic measurements. The focal plane reflector is a flat non-porous or reflective material, such as printed circuit board (PCB) that is placed behind and in parallel with an ultrasonic array of piezoelectric transducers. In accordance with the invention, the addition of the focal point reflector to the array of piezoelectric array permits the reflection of ultrasonic energy that may “fall” between the crystals in the array and then back into the crystal elements.

  • Patent number: 6804992
    Abstract: A system and method for eliminating confusion associated with checking valves, wherein additional test points are added to the measurement of a valve for ensuring the verification of the actual sources of leaks or turbulence. A base line measurement for the valve is established by measuring the level of ultrasonic sound at the two points upstream from the valve. The level of the ultrasound at two downstream points is then measured. The value of the ultrasound at the downstream test points is compared to the values of the ultrasound at the upstream test points. If the values of ultrasound at the downstream test points are higher than the values of the ultrasound at the upstream test points, then the valve is leaking. If the values of the ultrasound at the downstream test points are close to or lower than the values of the ultrasound at the upstream test points, then the valve is not leaking, i.e., the valve is good.

  • Patent number: 6707762
    Abstract: A method and apparatus for detecting leaks and mechanical faults by way of an ultrasonic device. An output from a variable gain amplifier is supplied to a pair of heterodyning circuits, i.e., a dual heterodyning circuit. At each respective heterodyning circuit, the output signal from the variable gain amplifier is multiplied by a local oscillator that is internal to each circuit. The dual heterodyning circuit is used to provide an enhanced input transducer signal for spectral analysis. This permits the capture of low level frequency components for extraction during spectral analysis. The dual heterodyning circuit of the present invention to provide the enhanced spectrum to thereby permit an easy determination of whether the resonance is mechanical or electrical becomes clear. In addition, fault frequencies are also more easily discernable. In other words, the enhanced signal output provides a lower signal to noise ratio such that the ease with which frequency components are analyzed is increased.

  • Patent number: 6655214
    Abstract: An externally-powerable sensor is described for detecting ultrasonic energy and for providing an accurate indication of the level of such energy to an external monitoring device over a wide dynamic range. A first electrical signal proportional to the detected ultrasonic energy is chopped by the output of a free-running multivibrator to generate a signal having a frequency differing from the frequency of the first signal by an amount within the audio frequency range. Such difference signal is selectively amplified to concentrate the spectral energy of the difference component in a lower portion of the audio range. A low pass filter extracts, from the so-concentrated difference signal, a modified audio signal whose frequency content is at the lower end, illustratively 0-6 KHz, of the spectrum of the concentrated difference signal. The output of the low pass filter is processed to generate a DC output current that is proportional to the detected ultrasonic energy level.
