Abstract: Accurate and effective methods for measuring cardiovascular and respiratory parameters are provided. The method for deriving a depth-specific photoplethysmography (PPG) signal from multi-wavelength PPG signals includes choosing light wavelength combinations, calibrating a multi-layer light-tissue interaction model referring to a physiological signal, and generating the depth-specific PPG signal from the multi-wavelength PPG signals based on the calibrated light-tissue interaction model. The disclosed method for cuff-less blood pressure measurement includes recording a physiological signal and multi-wavelength PPG signals of a predetermined body part, deriving the depth-specific PPG signal reflecting the arterial blood volume with the physiological signal as a reference, calculating the pulse transit time (PTT) from the physiological signal and the derived arterial blood PPG signal, and calculating the blood pressure from the calibrated PTT and blood pressure relationship.

Abstract: Systems and methods for designing RF pulses using a technique that directly controls temperature rise via a compression model that is based on virtual observation points (“VOPs”) are provided. Thermal pre-simulations are first carried out for a given RF exposure time, coil, and subject model in order to obtain complex temperature matrices, after which the compression scheme follows. As one example, the thermal model employed can be Pennes' bio-heat equation. Focusing design constraints on the temperature rise instead of the absolute temperature allows for uncertain parameters to be dropped from the thermal model, making it more robust and less prone to errors. In some embodiments, the algorithm used for RF pulse design is the active-set (“A-S”) method.

Abstract: A device is described having a first surface having a plurality of first areas and a second surface having a plurality of second areas. The first surface and the second surface are opposed to one another and can move relative to each other from at least a first position where none of the plurality of first areas, having a first substance, are exposed to plurality of second areas, having a second substance, to a second position. When in the second position, the plurality of first and second areas, and therefore the first and second substances, are exposed to one another. The device may further include a series of ducts in communication with a plurality of first second areas to allow for a substance to be disposed in, or upon, the plurality of second areas when in the first position.

Abstract: System and method based upon an OFDM symbol, including a cyclic prefix (CP), that is received after being transmitted over a multiple access channel, wherein the CP is removed, and a Hann window is applied to the symbol. FFT is then applied to the Hann windowed symbol to obtain the frequency domain subcarriers. The pilot symbols are filtered accordingly to obtain Hann windowed pilots to estimate effective channel. Inter-carrier interference is calculated and removed.
Abstract: A method includes a mobile device receiving data from a first beacon in a plurality of beacons, wherein the data indicates a plurality signals strengths of signals received by the first beacon from the other beacons in the plurality of beacons. The mobile device uses multivariable regression based on the data received from the first beacon and signal strengths of signals received by the mobile device from the other beacons in the plurality of beacons to determine distances from the mobile device to the beacons. The mobile device determines a location of the mobile device based on the determined distances.
Abstract: Apparatuses, systems, ambient RF backscatter transceivers, and methods for communicating using MIMO and spread spectrum coding of backscattered ambient RF signals are described. An example system may include an ambient RF backscatter transceiver that include an antenna configured to receive a backscattered ambient radio frequency (RF) signal, and a receiver coupled to the antenna. The receiver may be configured to demodulate the backscattered ambient RF signal using one of multiple input, multiple output multiplexing demodulation or spread spectrum code demodulation to retrieve the first data. The backscattered ambient RF signal may be generated by backscattering an ambient RF signal at a first frequency. The ambient RF signal may be configured to provide other data at a second frequency.
