Abstract: A full-duplex self-interference cancelling system operable in 28 GHz data rate levels, therefore well compatible with 5G systems such as massive MIMO transmitter-receiver radios and mm-waves, designed to include an antenna to improve signal-to-noise ratios (SNR) and elimination of self-interference-based noise and an adaptive, blind performing self-interference canceller module. In other words, the present invention comprises a self-interference canceller using variable-gin amplifiers to adjust a receiving signal post-dissection into in-phase and quadrant constituents thereof via an I/Q modulator, entire process of which is overseen and dictated by a digital control block.

Abstract: The present invention presents unit cell architecture for infrared imaging, which has two input stages covering for both low and high light levels, and automatic input selection circuitry inside to extend dynamic range. The invention mainly helps to extend dynamic range of near visible (NIR) and short wave infrared (SWIR) image sensors by improving SNR value. The idea is applicable to not only infrared bands including NIR, SWIR, MWIR and LWIR but also full spectrum light.

Abstract: The present invention is directed to methods and a bio-capacitor sensing device for the detection of toxic chemicals using bacteria. The sensing platform comprises gold interdigitated capacitor with a defined geometry, a layer of carboxy-CNTs immobilized with viable E. coli cells as sensing elements. Also included are methods of making the bio-capacitor device and methods for detecting toxic chemicals that induce cellular stress response. The present innovation discloses the development of a bio capacitor chips immobilized with carboxy-CNTs tethered E. coli bacteria. In addition, the present invention also includes determination of behavior and characteristics of chemically stimulated bacteria on biochip using electric field including frequency and/or amplitude as controlling parameters.

Abstract: The present invention proposes a CMOS sensor pixel with a pulse frequency modulated digital readout integrated circuit (DROIC) comprising a photon sensitive element for receiving a plurality of photons and providing a charge signal indicative of the received photons, an integration capacitor connected to said photon sensitive element for determining a cumulative signal based on the charge signal for a certain integration time and producing an integrator output signal based on the cumulative signal and a comparator connected to the integrator for producing a comparator output signal. Each of said pixels further comprises a DAC that switches at each clock cycle following the end of an integration time and two counters respectively counting number of resets of said integration capacitor and voltage difference between an integrator output residue signal and a reference voltage of said comparator.
