  • Publication number: 20210002421
    Abstract: In one or more embodiments, the present invention is directed to a novel method for synthesizing Mg(BHT)2(THF)2 catalyst, which has several advantages over previous methods. Dry toluene or pentane are not required for synthesizing the catalyst, and the reaction is done in a bulk solution of BHT and THF. Further, because the Mg(BHT)2(THF)2 is made in a one-step (“one-pot”) synthesis, the time required for synthesizing and drying the catalyst is reduced. Using the new method of the present invention, the Mg(BHT)2(THF)2 is pure after removing excess THF, thereby eliminating the need for washes and recrystallization.

  • Patent number: 10875015
    Abstract: Methods for making porous materials having metal alloy nanoparticles formed therein are described herein. By preparing a porous material and delivering the precursor solutions under vacuum, the metal precursors can be uniformly embedded within the pores of the porous material. Once absorption is complete, the porous material can be heated in the presence of one or more functional gases to reduce the metal precursors to metal alloy nanoparticles, and embed the metal alloy nanoparticles inside of the pores. As such, the metal alloy nanoparticles can be formed within the pores, while avoiding surface wetting and absorption problems which can occur with small pores.

  • Patent number: 10849710
    Abstract: An imaging and display system for guiding medical interventions includes a wearable display, such as a goggle display, for viewing by a user. The display presents a composite, or combined image that includes pre-operative surgical navigation images, intraoperative images, and in-vivo microscopy images or sensing data. The pre-operative images are acquired from scanners, such as MRI and CT scanners, while the intra-operative images are acquired in real-time from a camera system carried by the goggle display for imaging the patient being treated so as to acquire intraoperative images, such as fluorescence images. A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.

  • Patent number: 10816415
    Abstract: A flexible sensor for monitoring operating parameters, including pressure and temperature, of a flexible structure, such as a tire, provides electrodes and an active area that are formed of flexible materials. In particular, the active area may be formed from an elastomeric piezoresistive material, such as an ionic liquid-polymer. The flexible properties of the sensor allow it to be readily incorporated into the body of a tire during manufacture. This allows the operating parameters of the tire to be monitored, such as in real-time, while the tire is in operation. Furthermore, the sensor is formed of materials that allow the sensor to be formed using additive manufacturing techniques, such as 3D (three-dimensional) printing. As such, the sensor may be 3D printed together with another structure, such as a tire tread, so that the sensor is integrated therein.

  • Patent number: 10809170
    Abstract: A dynamic mechanical analysis system provides an actuator that imparts expansion and contraction forces (e.g. shear force) to a viscoelastic material at high frequencies. Such high frequency analysis allows for the direct and accurate measurement of the characteristics of the material at high expansion/contraction frequencies directly, without the use of additional predictive analysis techniques, such as time-temperature superposition. The system also utilizes a clamping system, whereby two different sections of the viscoelastic material are held in place between by a pair of fixed clamps and a force member that is moved by the actuator. As such, the system is able to subject the viscoelastic material sample to simulated “road” conditions to identify various performance properties associated with the material sample.

    Abstract: An optical imaging system to image a target object includes a light source configured to emit one or more light rays to illuminate the target object and an image detector configured to capture a three-dimensional topography image of the target object when emitted light is emitted from the target object in response to being illuminated by the light rays emitted by the light source. A fluorescence image detector captures a fluorescence image of the target object when fluorescence is emitted from the target object in response illumination by light rays emitted by the light source. A controller instructs the image detector to capture the 3D topography image and the fluorescence image detector to detect the fluorescence image of the target object intraoperatively and to co-register and simultaneously display intraoperatively the co-registered topography and fluorescence information to the user via a display.
