  • Transformer shielding
    Patent number: 7477120
    Abstract: An electrical transformer having a core with two core portions having a shield for electrically shielding one core portion from the other core portion.
    Type: Grant
    Filed: August 13, 2001
    Date of Patent: January 13, 2009
    Assignee: Bose Corporation
    Inventors: Wenjian Gu, Robert P. Parker, James A. Sozanski
  • Tracking power supply controlling
    Patent number: 6535399
    Abstract: The output voltage of the output of a power supply for providing power to an audio amplification and transduction system having a plurality of channels with each channel transmitting an audio signal includes monitoring the amplitude of the audio signals and providing a highest amplitude signal representative of the contemporary highest amplitude of the audio. AC electrical power has a variable frequency controlled by the highest amplitude signal and is converted to DC voltage having the output voltage related to the variable frequency. This DC voltage is delivered to the channels.
    Type: Grant
