20110075872 | System and Method for Optimizing the Strength and Orientation of the Inductive Field of a Hearing Aid Compatible Device - A system and method provides optimization of the strength and orientation of the inductive field of a hearing aid compatible (“HAC”) device, relative to a telecoil in a user's hearing aid. One aspect provides control of the drive level of a transmitting telecoil contained in the HAC device. Other aspects provide steering of the inductive field of the device by using a telecoil array and controlling the amplitude or phase of the signals transmitted by each telecoil in the array to create a composite field. Another aspect provides a plurality of transmitting telecoils arranged such that each telecoil has a different orientation, and a plurality of switches for controlling which transmitting telecoil is active. The user may then select the telecoil having a preferred orientation. Another aspect allows a transmitting telecoil to be physically oriented to an optimal position by embedding the telecoil in a substantially spherical element. | 03-31-2011 |
