Publication number: 20110270124Abstract: A method and apparatus for utilizing the benefits of encoded signal transmission and reception to enhance the performance of medical testing devices (100) adapted to evoke and measure biological response signals such as auditory evoked potentials (AEP), and the auditory brainstem response (ABR) signals in particular. Auditory stimuli, such as clicks, are presented to the ear of a human patient, in a predetermined encoded sequence, resulting in the generation of auditory responses and bio-electric response signals in the human patient. These response signals from the patient are acquired and observed, and are processed according to the predetermined encoded sequence in which the auditory stimuli were presented to the patient's ear in order to extract the desired auditory evoked potential signals or ABR signals.Type: ApplicationFiled: July 11, 2011Publication date: November 3, 2011Applicant: EVEREST BIOMEDICAL INSTRUMENTS CO.Inventor: Elvir Causevic

Publication number: 20100185115Abstract: Apparatus (10) for evoking and recording bio-potentials from a human subject and methods of use are described. The apparatus (10) includes a flexible member (18) with a layer of conductive material (12) disposed thereon for contacting a skin surface on the human subject. The dimensions and shape of the flexible member (18) are adapted for conforming contact between the conductive material (12) and the skin surface. A stimulus delivery element (28) is coupled to the flexible member (18) for delivering a sensory stimulus to the subject to evoke bio-potentials, which are detected and received through the layer of conductive material (12).Type: ApplicationFiled: February 23, 2010Publication date: July 22, 2010Applicant: Everest Biomedical Instruments, Co.,Inventors: Elvir Causevic, Christian Christiansen, Eldar Causevic

Publication number: 20080243021Abstract: An apparatus for monitoring bioelectric signals of a patient which includes a processing system and an interface for receiving external electrical signals representative of a condition of the patient. The interface is configured to convey a representation of the received external signals to the processing system, and includes a common mode cancellation amplifier circuit which is adapted to reduce common mode signal noise present in the external signals.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Applicant: EVEREST BIOMEDICAL INSTRUMENTS CO.Inventors: Elvir Causevic, Randall J. Krohn

Patent number: 7054453Abstract: A method and apparatus for de-noising weak bio-signals having a relatively low signal to noise ratio utilizes an iterative process of de-noising a data set comprised of a new set of frames. The method separately performs a non-linear de-noising operation on each of the component frames and combines the resultant de-noised frames to form a combined resultant de-noised input signal. The method is preferably carried out in a digital processor.Type: GrantFiled: March 29, 2002Date of Patent: May 30, 2006Assignee: Everest Biomedical Instruments Co.Inventors: Elvir Causevic, Eldar Causevic
