摘要:
A system that includes an implanted medical device such as an auditory prosthesis having a capacity to conduct communications on two channels to establish an association for communication with another electronic device. One of the channels is preferably a short range or near field channel, and the other channel is a broadcast channel. A method of asynchronous communication using both channels for establishing the association is also described.
摘要:
An active medical device, including an input receiver configured to receive a frequency-varying input signal, and a functional component that reacts to the input signal and consumes power at a rate dependant on the frequency of portions of the input signal to which the functional component reacts, wherein the active medical device is configured to adjust one or more portions of the input signal corresponding to portions of the input signal where the functional component consumes power at a rate that is greater than that of other portions of the input signal.

A BTE prosthetic device for use in a medical system or prosthesis comprises a connector configured to mechanically attach an auxiliary device of the system to the BTE prosthetic device. The connector is electrically connected to a transceiver of the BTE prosthetic device. The connector operates as an electromagnetic antenna for transmitting and/or receiving signals between the BTE prosthetic and other components of the medical system.

Methods, systems, and devices for receiving a data signal and a power signal by a hearing prosthesis are disclosed. An input signal is received at a first unit of a hearing prosthesis. The first unit receives the input signal at a wired interface module that conforms to a standardized interface. The first unit identifies a data signal and a power signal included in the input signal. The first unit transfers at least a portion of the power signal to a second unit of the hearing prosthesis. The second unit is implanted in a body and is configured to stimulate an auditory organ, allowing a user to perceive at least a portion of a sound.

A system includes an earhook having a connector for coupling to a behind-the-ear component of a hearing prosthesis. The earhook further includes a transducer and combined electromagnetic (EM) and magnetic induction (MI) antenna circuitry coupled to the transducer. The combined EM and MI antenna circuitry also includes an electrically conductive portion of the transducer and at least one inductor.
摘要:
A communication system for an active implantable medical device. The communication system includes an isolation transformer a coil coupled to the isolation transformer, and first and second communication components each coupled to the isolation transformer such that the first and second communication components are electrically isolated from the coil, and such that the isolation transformer enables the first and second communication components to communicate, via magnetic induction (MI) using the coil, with at least one external component.

Systems, methods, and apparatuses may be used to charge battery-powered devices using a charging device. Such battery-powered devices include the external portions of auditory prostheses or other medical devices. The charging device prioritizes the charging requirements of a number of batteries and transfers power to one or more batteries. The charging device also sends a signal to activate an indicator on each external portion.
摘要:
An external device of an implantable medical system includes a coil that is substantially disposed in an XY-plane. When a first AC electrical signal is passed through the coil, the coil generates an alternating magnetic field that represents the AC electrical signal. The electrical signal can include at least one of power or data. The device also includes a cylindrical shaped permanent magnet with base substantially parallel to the XY-plane. The magnet can be is used to position the external device with respect to an implantable device. Further, the device has a printed circuit board that includes at least a portion that is substantially orthogonal to the XY-plane and the portion can also include an electrical ground plane. In addition, the device can include at least one sensor that is coupled to the portion of the substrate and to the ground plane.
摘要:
Methods, systems, and devices for determining a data rate for a communication between bilateral hearing prostheses are disclosed. A first hearing prosthesis transmits a first signal to a second hearing prosthesis during a first transmission interval. The second hearing prosthesis transmits a second signal to the first hearing prosthesis during a second transmission interval. The first signal includes an indication of a data rate for the second signal.
