20100246846 | Personal Acoustic Device Position Determination - Apparatus and method for determining an operating state of a personal acoustic device by receiving a signal from one or more movement sensors indicating movement detected by the one or more movement sensors, wherein the one or more movement sensors are disposed on portions of the personal acoustic device structured to be worn on a user's head to enable the one or more movement sensors to detect rotational movements of a user's head when the personal acoustic device is in position on the user's head such that a casing of the personal acoustic device is adjacent an ear of the user. | 2010-09-30 |
20100246847 | Personal Acoustic Device Position Determination - Apparatus and method for determining an operating state of a personal acoustic device by receiving signal from first and second movement sensors indicating movement detected by each, wherein the first movement sensor is disposed on a portion of the personal acoustic device structured to be worn on a user's head to enable the first movement sensors to detect movements of a user's head when the personal acoustic device is in position on the user's head such that a casing of the personal acoustic device is adjacent an ear of the user, and wherein the second movement sensor is disposed on a portion of the personal acoustic device structure to not be worn on a user's head. | 2010-09-30 |
20100246848 | MOTIONAL FEEDBACK SYSTEM - An audio amplifier is operated in an audio system with optimized source impedance to minimize distortion in a loudspeaker that is paired with the audio amplifier. The audio amplifier provides an amplified audio signal to drive the loudspeaker. A variable output impedance of the audio amplifier is controlled using a feedback control loop to allow negative output impedance at low frequencies that changes to positive output impedance at higher frequencies. The change from negative output impedance to positive output impedance occurs at a determined threshold frequency or determined transitional frequency band. | 2010-09-30 |
