In another mode of operation, the acoustic stethoscope substantially provides only acoustic ... 03/15/07 - 20070058818 - Stethoscope apparatus [Means for Solving]A stethoscope apparatus 10 according to the embodiment integrally mounts a speaker 9 and a microphone 8; accordingly, the speaker 9 can reproduce sounds obtained with the microphone 8. For instance, when a physician explains the pathology and so on to a patient with the patient allowed hearing ... 12/21/06 - 20060285696 - High noise environment stethoscope A stethoscope having noise suppression features that make it suitable for use in high noise environments. The stethoscope includes ear pieces connected to signal processing components connected to a transducer in a chest piece that includes at least one suppression barrier extending from it. In at least one embodiment, the ... 11/02/06 - 20060245597 - Detection of coronary artery disease using an electronic stethoscope The disclosure describes an electronic stethoscope system that automatically detects coronary artery disease in patients. The system uses an electronic stethoscope to record acoustic data from the fourth left intercostal space of a patient. A processing technique is then applied in order to filter the data and produce Fast Fourier ... 10/12/06 - 20060227979 - Contact type electronic stethoscope with a noise interference resisting function for auscultation The present invention describes a contact type electronic stethoscope with a noise interference resisting function for auscultation, and the stethoscope includes a chest piece for contacting a patient's body, a contact type microphone installed in the chest piece for receiving sounds of patient's organs, and an elastic member disposed on ... 09/21/06 - 20060210090 - Personal hearing evaluator A hand-held device includes an audio transducer (i.e., speaker) for delivering acoustic test stimuli to a test subject within the direct sound field range of the device. The device accurately delivers multi-level and multi-frequency test stimuli for the subjective response by the test subject holding the device. An ultrasonic position ... 09/07/06 - 20060198533 - Method and system for continuous monitoring and diagnosis of body sounds A method and system is invented for automated continuous monitoring and real-time analysis of body sounds. The system embodies a multi-sensor data acquisition system to measure body sounds continuously. The sound signal processing functions utilize a unique signal separation and noise removal methodology by which authentic body sounds can be ... 05/11/06 - 20060098825 - Electronic adaption of acoustical stethoscope A stethoscope adapter receives and converts a stethoscope transducer signal using a predetermined inverse function. The adapter then transmits the converted signal as an acoustical signal through a tube connector. With this arrangement, the adapter converts the signal to compensate for undesirable non linear transmission effects through known stethoscopes. The ... 03/16/06 - 20060056641 - Method and system for physiological signal processing A method and system for processing of physiological signals is provided. The system processes information signals in subband-domain associated with the physiological signals in time-domain. The information signals are obtained by one or more over-sampled filterbanks. The method and system possibly synthesizes the subband signals obtained by subband processing. The ... 01/26/06 - 20060018487 - Transducer for sensing body sounds The structure and method of manufacture of diaphragms for use in electronic body sound transducers is described. The diaphragm is a critical element in shaping the overall amplitude and frequency response of such transducers. Various embodiments of novel diaphragms are described, each of which offers particular advantages in shaping the ... 10/20/05 - 20050232434 - Transducer for bioacoustic signals In well-known electronic stethoscopic transducers the sensitive element is influenced by signals transmitted via the skin, and the rear side is enclosed in a housing to prevent airborne noise from reaching the sensitive element. According to the invention, an improved signal-to-noise ratio is obtained by letting the transducer be a ... 09/15/05 - 20050201566 - Electronically amplified stethoscope [e.a.s] (with optional recoding and data transfer capability) The nature of the technical disclosures of my invention is that a battery powered electrical amplifier is combined with the typical stethoscope, such that by the use of a mini-microphone placed within the membrane of the stethoscope's drum, those sounds heard by the stethoscope are detected by the microphone, then ... 08/25/05 - 20050185799 - Method of monitoring equipment and alert device A device and method that interfaces between a medical device and a call alert system. The device includes a microphone that senses an audio signal generated by the medical device when the medical device alarms. ... 07/21/05 - 20050157888 - Electronic stethoscope with piezo-electrical film contact microphone The present invention discloses an electronic stethoscope with a Piezo-Electrical Film contact microphone comprising a stethoscope head with a Piezo-Electrical Film contact microphone inside, and the stethoscope head is electrically connected to a circuit and a microcontroller unit (MCU). The microcontroller unit is connected to a front-end operational amplifier (OP-amp) ... 07/21/05 - 20050157887 - System for outputting acoustic signal from a stethoscope Disclosed is an output system for displaying an auscultatory sound signal such as heartbeat or respiratory sounds generated from the interior of a body in real time. The output system includes a stethoscope and a computer. The stethoscope includes at least a) a diaphragm to he brought into contact with ... 06/30/05 - 20050141729 - Ear-attaching type electronic device and biological information measuring method in ear-attaching type electronic device An ear-attaching type electronic device includes: a body part supported in a vicinity of a lower part of an occipital part when the device is attached; a pair of arm parts extending from the body part, to which a connecting member is placed therein; and a pulse sensor section for ... 06/16/05 - 20050129253 - Portable audio device with body/motion signal reporting device A portable audio device includes an audio signal generating device for generating an audio signal, a body/motion signal detecting device for detecting and generating a body/motion signal, a signal loop selecting circuit which is coupled to the body/motion signal detecting device, a timer control circuit which generates a loop selection ... ### FreshPatents.com Support |
