Patent number: 11937048Abstract: An implantable hearing unit is provided that includes an implantable microphone, a rechargeable power storage device and a speech signal processor. The hearing unit further includes a signal coupling device that is adapted for electrical interconnection to an implantable auditory stimulation device, which is operative to stimulate an auditory component of a patient. Such a stimulation device may include cochlear implants, brain stem stimulation systems, auditory nerve stimulation systems, and middle or inner ear transducer systems. The signal coupling device is operative to provide processed drive signals from the signal processor to the stimulation device as well provide power from the power storage device to operate the stimulation device. In one arrangement, the signal coupling device is a wireless coupling between first and second coils. In such an arrangement, the hearing unit may be utilized with an existing implanted stimulation device to make that device a fully implanted hearing system.Type: GrantFiled: October 21, 2019Date of Patent: March 19, 2024Assignee: Cochlear LimitedInventors: James Frank Kasic, James R.

Patent number: 11039256Abstract: An implanted microphone is provided that allows for isolating an acoustic response of the microphone from vibration induced acceleration responses of the microphone. The present invention measures the relative motion between a microphone diaphragm, which is responsive to pressure variations in overlying media caused by acoustic forces and acceleration forces, and a cancellation element that is compliantly mounted within a housing of the microphone, which moves primarily in response to acceleration forces. When the microphone and cancelation element move substantially in unison to acceleration forces, relative movement between these elements corresponds to the acoustic response of the microphone diaphragm. This relative movement may be directly measured using various optical measuring systems.Type: GrantFiled: May 8, 2018Date of Patent: June 15, 2021Assignee: Cochlear LimitedInventor: James R. Easter

Publication number: 20100318167Abstract: An implantable neurostimulation electrode array may include a flexible, electrically non-conductive carrier, and a plurality of electrodes supportably interconnected to and spaced along a length of a carrier. In various embodiments, different ones of at least some of the plurality of electrodes may comprise corresponding contact surfaces having different areas. The different surface areas may be achieved by defining a different area per unit length of the carrier and/or by defining a different total length (e.g. as measured along a length of the carrier). In some embodiments, insulator portions having different corresponding lengths may be disposed between different adjacent ones of the electrodes. The insulated portions may be integrally defined with the carrier. Electrical connection lines may be embedded within the carrier. In a manufacturing method, a plurality of electrodes may be supportably interconnected to a first side of a sacrificial substrate and a carrier may be interconnected to the electrodes.Type: ApplicationFiled: April 19, 2010Publication date: December 16, 2010Applicant: Otologics, LLCInventors: Brian M.

Patent number: 5617311Abstract: An information system for a complex plant which clearly presents to the operator, in parallel as alarms, abnormal process changes which the operator can, at his discretion, manually respond to either to prevent conditions from deteriorating further to the point where automatic protective actuations will be initiated or where automatic protective actuations have not been completed because of a malfunction or were completed but have not been successful. Such alarms are displayed on a dedicated alarm display panel which spatially groups components and subsystems to show appropriate relationships, with the alarm messages shown in the associated area of the display so that possible disturbance propagation can be foreseen. Messages related to uncompleted automatic protective actuations may include a list of faults which prevented completion of those actuations.Type: GrantFiled: February 6, 1995Date of Patent: April 1, 1997Assignee: Westinghouse Electric CorporationInventors: James R. Easter, Albert J. Impink, Jr.

Patent number: 5032978Abstract: A display, a display method and an apparatus are disclosed which produce a summary display depicting function states using discrete state bars centered in one window of a two-window display. The other window on the summary display includes meters for the parameters along the active path of the status tree for the most relevant function as determined by the operator. Each meter indicates not only the current value of the parameter being monitored but the ranges of the different function states as they correspond to the parameter being displayed by the meter. Each meter also carries a data quality indicator. A second level display is provided which depicts the status tree with the active path highlighted allowing the operator to review the decision made by the status tree.Type: GrantFiled: September 28, 1989Date of Patent: July 16, 1991Assignee: Westinghouse Electric Co.Inventors: Craig D. Watson, Mary C. Eastman, David D. Woods, John P. Carrera, James R. Easter, Melvin H. Lipner, William C. Elm, A. Dean Mundy
