  • Patent number: 11929071
    Abstract: A method operates a hearing device system which has a hearing aid and a peripheral device which provides a voice-controlled digital assistant. A microphone signal from the hearing aid is examined for own voice components of the wearer of the hearing aid. If own voice components are detected by the hearing aid the microphone signal is examined for a pre-defined activation command for the digital assistant. If the activation command is recognized, a portion of the microphone signal representing the activation command and a subsequent speech sequence is processed by the hearing aid for a speech recognizer of the digital assistant using an algorithm. The processed portion of the microphone signal is transmitted to the peripheral device.

  • Patent number: 8314218
    Abstract: The present invention relates to methods for synthesizing macrolide compounds which are known to have antibacterial activity, and are useful in the therapy of bacterial infections in mammals. More specifically, the invention relates to methods for synthesizing the macrolide antibiotic, gamithromycin utilizing a novel configuration of catalysts, chemical structures, and/or methods. An embodiment of the present invention may include allowing multiple chemical reactions to proceed without the isolation of chemical intermediates. Thus, multiple reactions may occur in one reaction vessel allowing for a considerable decrease in the cycle-time. The present invention also provides a novel method for inhibiting degradation while isolating a structure of a pharmaceutical composition.
