  • Patent number: 11742958
    Abstract: A method of using a HBC device includes enabling electro-quasistatic communication on a transmitter, wherein the enabling electro-quasistatic communication includes receiving an activation signal through an input. The enabling the electro-quasistatic communication additionally includes transmitting a digital data signal to a transmitter logic circuit. The enabling the electro-quasistatic communication further includes modulating an electro-quasistatic carrier signal by the digital data signal using a modulator, thereby producing a modulated electro-quasistatic signal. Additionally, the enabling the electro-quasistatic communication includes transmitting the electro-quasistatic signal from the transmitter logic circuit to a general purpose input output circuit. Furthermore, the enabling the electro-quasistatic communication includes coupling the electro-quasistatic signal on a human body through an electrode, thereby enabling electro-quasistatic communication. The transmitter includes the electrode.

  • Patent number: 11374602
    Abstract: A communication interference rejection system comprising a receiver operatively connected to a device connected to a body of a user. The receiver is configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, the interference component due to human body antenna effect. The receiver is configured to integrate the signal using a relatively low-gain analog integrator and then digitally differentiate the output of said integration.
