摘要： A pressure regulating earplug for regulating the rate of change of pressure inside an ear to minimize the pressure differential between the middle ear and a volume of the external ear cavity adjacent the ear drum is made of an ear plug adapted to fit tightly within the external ear cavity with no or minimal air leakage, and disposed within the earplug is a pressure regulator with a slow leak rate. Examples of the material which causes the pressure regulation include porous metal and porous ceramic material.

摘要： A low-cost, four-channel cochlear stimulation system utilizes a completely passive, implantable receiver/electrode array that is inductively coupled to an external wearable processor. The receiver/electrode array is formed in a silicone rubber carrier adapted to be implanted in a deaf patient. At one end of the receiver/electrode array, positioned subcutaneously near the surface of skin above the ear, four receiving coils are arranged in an appropriate pattern. Such receiving coils are held within an hermetically-sealed titanium case. At the other end of the receiver/electrode array, which may be pre-formed in a spiral to match the basal turn of the cochlea, and which is inserted in the cochlea, four ball electrodes are spaced apart along an inner radius of the spiral. Each electrode is electrically connected to a respective receiving coil. Each receiving coil is also electrically connected to a reference electrode typically located near the receiver-coil end of the array. The wearable processor senses audible sounds, converts the sensed sounds to corresponding electrical signals, and splits the electrical signals into four frequency bands or channels. A speech processing strategy applies the processed signals of each channel to each of four external coils, as a series of biphasic current pulses. The four external coils are aligned, using a suitable headpiece, with corresponding coils of the receiver/electrode array, thereby inductively coupling the biphasic current to a respective electrode of the implanted electrode array.
摘要翻译： 低成本的四通道耳蜗刺激系统利用完全无源的，可植入的接收器/电极阵列，其被感应耦合到外部可佩戴的处理器。 接收器/电极阵列形成在适于植入聋患者的硅橡胶载体中。 在接收器/电极阵列的一端，皮下放置在耳朵上方皮肤表面附近，四个接收线圈被布置成适当的图案。 这种接收线圈保持在密封的钛壳体内。 在接收器/电极阵列的另一端，其可以被预先形成为螺旋以匹配耳蜗的基部转弯并且被插入耳蜗中，四个球电极沿着螺旋的内半径间隔开 。 每个电极电连接到相应的接收线圈。 每个接收线圈也电连接到通常位于阵列的接收器线圈端附近的参考电极。 可穿戴处理器感测可听见的声音，将感测到的声音转换为相应的电信号，并将电信号分解成四个频带或频道。 语音处理策略将每个通道的处理信号应用于四个外部线圈中的每一个，作为一系列双相电流脉冲。 四个外部线圈使用合适的头部与接收器/电极阵列的相应线圈对准，从而将两相电流感应耦合到注入电极阵列的相应电极。

摘要： Improved approaches are disclosed to update existing hearing devices by downloading software resources over a network from a remote server to a local client. The software resources are then stored in the existing hearing devices, thereby upgrading the functionality or operation of the existing hearing devices. Accordingly, existing hearing devices are able to be upgraded at convenient locations in a largely automated fashion. The invention is particularly useful for hearing aids or other sound systems for the hearing impaired.
