    Abstract: A cured concrete and stone bore working tool and method of forming radially oriented discontinuities in a bore or perforation Ruined in a cured concrete or stone material such that, after use or application of the tool, the perforation formed in the cured concrete or stone material is configured to provide a non-planar adhesive interface and isolate a properly sized anchor or fastener from direct contact with the wall of the bore. Fasteners or anchors adhesively secured in bores previously treated with the bore treating tool exhibit improved creep failure performance as compared to fasteners adhesively secured to untreated bores.

    Abstract: An infant sleep pod providing passive and/or active safety features. The infant sleep pod provides a safe sleeping environment for infants sharing sleep areas with adults. The infant sleep pod provides a firm, flat, separate, portable, and dedicated sleep space for an infant. The infant sleep pod includes a base with a bed and sidewall, and a bridge extending across the bed. The bridge covers a head portion of the bed, while a foot portion of the bed is left open for inserting and removing the infant. The bridge prevents pillows and blankets from covering the bed and infant. The infant sleep pod also includes electronics for monitoring the sleep pod. The electronics include a sensor unit in the bridge and a control unit in communication with the sensor unit. The control unit and sensor unit are operable to detect unsafe conditions and, in response, generate alerts.

    Abstract: A camera assembly for use in a MRI machine. The camera assembly includes a Faraday cage defining a shielded cavity and an optical path mount constructed of a highly stiff, dense, and non-electrically-conductive material in the shielded cavity. The camera imager and lens are mounted to the optical path mount. The camera assembly includes a capacitor-based power regulation circuit. The optical path mount is not subject to eddy currents because it is non-electrically-conductive. The capacitor-based power regulation circuit includes very little ferrous material and is within the shielded cavity, to reduce eddy currents. The resulting camera assembly reduces vibrations and shaking in the magnetic field environment of the MRI machine.

    Abstract: A composition of graphene-based nanomaterials and a method of preparing the composition are provided. A carbon-based precursor is dissolved in water to form a precursor suspension. The precursor suspension is placed onto a substrate, thereby forming a precursor assembly. The precursor assembly is annealed, thereby forming the graphene-based nanomaterials. The graphene-based nanomaterials are crystallographically ordered at least in part and configured to form a plurality of diffraction rings when probed by an incident electron beam. In one aspect, the graphene-based nanomaterials are semiconducting. In one aspect, a method of engineering an energy bandgap of graphene monoxide generally includes providing at least one atomic layer of graphene monoxide having a first energy bandgap, and applying a substantially planar strain is applied to the graphene monoxide, thereby tuning the first energy band gap to a second energy bandgap.

    Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker (30), preferably a retro-grate reflector (RGR), is placed on the head or other body organ of interest of a patient (P) during a scan, such as an MRI scan. The marker (30) makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track motion of the organ of interest. A detector, preferably a camera (40), observes the marker (30) and continuously extracts its pose. The pose from the camera (40) is sent to the scanner (120) via an RGR processing computer (50) and a scanner control and processing computer (100), allowing for continuous correction of scan planes and position (in real-time) for motion of the patient (P). This invention also provides for internal calibration and for co-registration over time of the scanner's and tracking system's reference frames to compensate for drift and other inaccuracies that may arise over time.
