  • Patent number: 10844405
    Abstract: A method for the in vivo production of 1,3-butadiene from 2,4-pentadienoate is described (FIG. 1). Enzymes capable of decarboxylating 2,4-pentadienoate to 1,3-butadiene have been discovered. Recombinant expression of these newly discovered enzymes has resulted in the engineering of microorganisms capable of producing 1,3-butadiene when cultured in the presence of 2,4-pentadienoate. 1,3-butadienoate is an important monomer used in the manufacturing of rubbers and plastics. This invention will help to enable the biological production of 1,3-butadiene from renewable resources such as sugar, for example.

  • Patent number: 10839189
    Abstract: Methods, apparatuses, systems, and implementations of an ultra-compact RF (30 GHz-10 THz) imaging sensor topology that provides a new insight into the human skin are disclosed. The skin tissue is the largest organ in the body—both in weight and surface area—and stores valuable information that can revolutionize security biometrics and mobile health monitoring. The proposed compact sensor enables, for the first time, portable and wearable devices to perform superior biometric authentication compared to current fingerprint methods. Additionally, these devices could probe into the skin to monitor vital signs in real-time and enable mobile health monitoring.

  • Patent number: 10835184
    Abstract: A microelectromechanical device and method for neuroprosthetics comprises microactuators and microelectrodes. The microelectrodes are to be positioned in a nerve bundle and bonded with the microactuators through an interconnect. The position of each of the microactuators can be individually tuned through control signals so that the microelectrodes are implanted at desired positions in the nerve bundle. The control signals are transmitted to the microactuators and generated with a open-loop or closed-loop control scheme that uses signals acquired by the microelectrodes from the nerve bundle as feedback.

  • Publication number: 20200358396
    Abstract: Solar array fault detection, classification, and localization using deep neural nets is provided. Embodiments use a cyber-physical system (CPS) approach to fault detection in photovoltaic (PV) arrays. Customized neural network algorithms are deployed in feedforward neural networks for fault detection and identification from monitoring devices that sense data and actuate at each individual module in a PV array. This approach improves efficiency by detecting and classifying a wide variety of faults and commonly occurring conditions (e.g., eight faults/conditions concurrently) that affect power output in utility scale PV arrays.

  • Patent number: 10828800
    Abstract: Systems and methods are described for controlled crack propagation in a material using ultrasonic waves. A first stress in applied to the material such that the first stress is below a critical point of the material and is insufficient to initiate cracking of the material. A controlled ultrasound wave is then applied to the material causing the total stress applied at a crack tip in the material to exceed the critical point. In some implementations, the controlled cracking is used for wafering of a material.

  • Publication number: 20200349247
    Abstract: A smart hardware security engine using biometric features and hardware-specific features is provided. The smart security engine can combine one or more entropy sources, including individually distinguishable biometric features, and hardware-specific features to perform secret key generation for user registration and authentication. Such hybrid signatures may be distinct from person-to-person (e.g., due to the biometric features) and from device-to-device (e.g., due to the hardware-specific features) while varying over time. Thus, embodiments described herein can be used for personal device authentication as well as secret random key generation, significantly reducing the scope of an attack.

  • Patent number: 10823728
    Abstract: A method and system for analysis of protein interaction kinetics in microarray or whole-cell based formats includes positioning a sensor chip on a prism. The sensor chip is spotted with a plurality of target molecules. A movable printer head deposits a plurality of analyte droplets on predefined regions of the sensor chip surface. A light source transmits light through the prism to excite surface plasmon resonance on the sensor chip surface, whereby the plurality of target molecules bound to the upper surface are changing the SPR resonance angle and therefore the intensity of the reflected beam. A detector receives reflected light transmitted through the prism from the bottom surface. Signals from the detector are received and processed into kinetic data and microarray labeled data to determine molecular interactions and binding kinetic properties for the plurality of analyte droplets.
