  • Patent number: 11206163
    Abstract: The present disclosure includes a time-to-digital converter (TDC) based RF-to-digital (RDC) data converter for time domain signal processing polar receivers. Polar data conversion achieves better SNR tolerance owing to its phase convergence near the origin in a polar coordinate. The proposed RDC consists of a TDC for phase detection and an analog-to-digital converter (ADC) for amplitude conversion. Unlike the conversional data converter, the proposed ADC's sampling position is guided by the detected phase result from the TDC's output. This TDC assisted data-converter architecture reduces the number of bits required for the ADC. In addition, oversampling is no longer needed. With precisely controlled tunable delay cells and gain compensator, this hybrid data convertor is capable to directly convert Quadrature Amplitude Modulation (QAM) waveforms and Amplitude Phase Shift Keying (APSK) waveforms directly from the RF signal without down-conversion.

  • Patent number: 11166920
    Abstract: The devices, methods, and compositions disclosed herein accomplish robust cell encapsulation in polymer microparticles using a vertically oriented microfluidic device. A hydrophilic polymer precursor solution is flowed into a first inlet channel, which extends inward from an upper surface of the device housing. A hydrophobic fluid is flowed into a second inlet channel, which extends inward from a lower surface of the device housing. The two inlet channels meet at a junction, and an outlet channel extends away from the two inlet channels. When the two inwardly flowing streams meet at the junction, the polymer precursor solution disperses into the hydrophobic fluid. The dispersed precursor droplets are photopolymerized into microparticles as they travel through the outlet channel. The resulting microparticles are highly uniform, and are larger than conventionally formed microparticles. Cells of varying types can be encapsulated with high viability and spatial uniformity.

  • Patent number: 11140870
    Abstract: Vapor wake detection is a highly advantageous method and system for detecting explosives and other illicit substances. With vapor wake detection, a canine and a handler are used; however, unlike other detection schemes, the canine leads the handler. After the handler positions the canine in a desired location, the canine detects scents in the air that come to the canine. When the canine detects a trained scent, the canine leads the handler to or follows behind the carrier of the item with the scent. Once the carrier is identified by the handler, the proper personnel are contacted. To implement vapor wake detection effectively, specific rigorous training is utilized.

  • Patent number: 11069815
    Abstract: A thin-film transistor comprises an annealed layer comprising crystalline zinc oxide. A passivation layer is adjacent to the thin-film transistor. The passivation layer has a thickness and material composition such that when a dose of radiation from a radiation source irradiates the thin-film transistor, a portion of the dose that includes an approximate maximum concentration of the dose is located within the annealed layer. The annealed layer has a thickness and threshold displacement energies after it has been annealed such that: a) a difference between a transfer characteristic value of the thin-film transistor before and after the dose is less than a first threshold; and b) a difference between a transistor output characteristic value of the thin-film before and after the dose is less than a second threshold. The thresholds are based on a desired performance of the thin-film transistor.
