    Abstract: A method of forming a coating that includes depositing a multicomponent glass layer on a polymer substrate and depositing a heat absorbing layer on the multicomponent glass layer. Inducing spinodal decomposition of the multicomponent glass layer by annealing the heat absorbing layer, and etching at least one of a phase separated component of the multicomponent glass layer. The spinodal decomposition may be achieved through a pulse thermal or electromagnetic assisted annealing process. The coating may then be used as a hydrophilic surface, or may be fluorinated using conventional methods to produce the superhydrophobic coating.

    Abstract: A terahertz (THz) spectral imaging system includes a THz 2D imaging camera, a tunable THz bandpass filter before the THz camera, and a broadband THz light source. The tunable THz bandpass filter includes a visible or infrared laser source, a spatial light modulator modulating the light to generate a spatially structured light pattern, and a semiconductor plate onto which the light pattern is projected. The light pattern generates carriers in the semiconductor plate to turn it into a metamaterial THz bandpass filter, which is tunable by changing the light patterns. A controller controls the light patterns and the THz camera in a timing sequence to acquire multiple 2D THz images at different THz frequencies. Such THz spectral image data can be further combined with visible images and LiDAR images in a security surveillance system to automatically detect security threats using image fusion and deep learning techniques.

    Abstract: An ultrasonic transmitter includes a piezoelectric integrated thin film transistor (PITFT). The transistor includes a top gate electrode, a bottom gate electrode, and a piezoelectric layer. The piezoelectric layer generates vibrations in response to a voltage applied across the top gate electrode and the bottom gate electrode. The transistor includes micro-electrical-mechanical systems (MEMS) mechanically coupled to the PITFT. The MEMS includes a resonator that transmits ultrasonic pressure waves based on the vibrations.

    Abstract: A method for 3D printing an object, based on a 3D printable model of the object, includes scanning, by a first LiDAR sensor of a plurality of LiDAR sensors, a portion of the object while the object is being printed by a printer head. The method also includes generating an image of at least the portion of the object based on scanning the portion, generating a comparison by comparing the image with the 3D printable model, and sending a feedback signal that adjusts the printer head based on the comparison.

    Abstract: A device for producing polarized light includes a plurality of photonic crystal grid structures on a substrate. The plurality of photonic crystal grid structures includes one or more structured regions for the transmission of polarized blue light, polarized green light, and polarized red light. A green quantum dot layer is substantially positioned on the one or more structured regions for the transmission of polarized green light and a red quantum dot layer is substantially positioned on the one or more structured regions for the transmission of polarized red light. A blue light emitting diode array is disposed on the polarized light device such that the emission from the blue light emitting diode array facilitates the emission of red and green light from the red and green quantum dot layers.

    Abstract: A method for manufacturing a three-dimensional printed (3D-printed) object on a base plate. The method includes: depositing at least one block of a first material in a first layer directly onto the base plate; and depositing at least one block of a second material either in the first layer adjacent to the one or more blocks of the first material, or in a second layer directly onto the at least one block of the first material in the first layer. The first material is one of a non-auxetic structure or an auxetic structure, and the second material is the other one of the non-auxetic structure or the auxetic structure.

    Abstract: A video surveillance system with real-time object re-identification capabilities, which employs an object re-identification algorithm and an edge computing architecture. An operator monitors video images from the multiple cameras, and when a target object is observed, a target image containing the object is transmitted to all video cameras for object re-identification. Each video camera has dedicated processing circuitry that performs an object re-identification algorithm to identify the target in video images captured by that camera in real time. The algorithm calculates a frequency domain similarity measure between the target image and test images captured by the camera. The similarity measure in the frequency domain is calculated as a dot product of the 1D discrete Fourier transforms of the target image data and of the test image data. The multiple cameras also transmit object re-identification results to each other to achieve more efficient and intelligent object re-identification.
