  • Patent number: 11412952
    Abstract: A low complexity, low powered, non-invasive, and wearable system for detecting pulmonary edema and emphysema by estimating an average dielectric constant includes a radio frequency (RF) sensor array, which is fabricated along a flexible substrate, a data collection unit, a body area network (BAN), and a post-processing unit. The flexibility of the flexible substrate allows the RF sensor array to worn around the chest region. A plurality of ports of the RF sensor array is used to measure a set of transmission coefficients. The data collection unit accumulates and transfers the set of transmission coefficients to the post-processing unit, wherein the BAN is used during the transfer process. At the post-processing unit, the average dielectric constant is estimated. Since the average dielectric constant can be used as a measure of fluids and air within the lungs, pulmonary edema and emphysema may be detected using the average dielectric constant.

  • Patent number: 11394467
    Abstract: A method for optical communication between first and second transceivers over a channel in a free-space medium involves receiving a binary string of uniformly distributed bits and converting them into probabilistically-shaped unipolar M-pulse amplitude modulated (M-PAM) symbols using distribution matching. The probabilistically-shaped unipolar M-PAM symbols are mapped into a binary bit stream, which are used to generate, at a forward error correction rate, parity bits. The parity bits are mapped to uniformly-distributed unipolar M-PAM parity symbols. The probabilistically-shaped unipolar M-PAM symbols and the uniformly-distributed unipolar M-PAM parity symbols are multiplexed to form a codeword that is used to modulate the intensity of a laser so as to transmit the codeword.
