  • Patent number: 10666306
    Abstract: A technique is presented for correcting phase distortion in a digital wireless transmitter. The technique includes: receiving an RF signal in an analog domain by a digital-to-RF modulator; amplitude modulating, the RF signal in accordance with a digital input code; and introducing delay in a signal path traversed by the RF signal before the digital-to-RF modulator using a delay circuit. The duration of the delay depends upon the value of the digital input code and substantially cancels out the phase distortion introduced by the digital wireless transmitter.

  • Patent number: 10656062
    Abstract: The disclosure relates to an irreversible dosimetric shock-detection substrate as well as related articles and methods. The shock-detection substrate incorporates a plurality of microcapsules serving as an irreversible means for detecting impact on the substrate. A shock above a characteristic threshold level experienced by the substrate induces an irreversible detectable change associated with the microcapsules upon shock-induced rupture. The irreversible detectable change provides a tamper-proof and non-electronic means for detecting a shock or impact. The shock-detection substrates can be incorporated into a variety of articles and used in a variety of settings, for example to monitor personal safety, to monitor article integrity, to monitor the end of the useful life of the shock-detection substrate itself, or in any other setting where it is desirable to irreversibly detect and/or localize a shock event.

  • Patent number: 10645886
    Abstract: The disclosure relates to a plant growth apparatus and related system to grow and maintain plants under controlled biotic conditions, for example to grow axenic (microbe-free) plants, gnotobiotic (defined microbiota) plants, and holoxenic (complex, or undefined microbiota) plants. This system allows aseptic bottom irrigation with water, soluble nutrients, chemicals, and/or microbiota. Plants can be inverted for dipping and/or vacuum infiltration. The system also allows for passive (gravity) drainage, thereby allowing for gas exchange and preventing root anoxia. A variety of plant growth substrates can be used within the plant growth apparatus as a plant growth medium. The plant growth apparatus, containing the growth substrate medium, can be completely flushed via the drainage port to remove potential toxic byproducts of the sterilization processes. The entire system is suitably constructed using autoclavable material.

  • Publication number: 20200138305
    Abstract: Current oscillometric devices for monitoring central blood pressure (BP) maintain the cuff pressure at a constant level to acquire a pulse volume plethysmography (PVP) waveform and calibrate it to brachial BP levels estimated with population average methods. A physiologic method was developed to further advance central BP measurement. A patient-specific method was applied to estimate brachial BP levels from a cuff pressure waveform obtained during conventional deflation via a nonlinear arterial compliance model. A physiologically-inspired method was then employed to extract the PVP waveform from the same waveform via ensemble averaging and calibrate it to the brachial BP levels. A method based on a wave reflection model was thereafter employed to define a variable transfer function, which was applied to the calibrated waveform to derive central BP.
