Abstract: An overhead ceiling device for vehicles, such as airplanes. The device includes a faceplate, keypad, PCB, body, light module, and an outer mounting compression ring body. The faceplate includes lens for lights and holes for buttons. Keypad includes buttons that can protrude from the holes in the faceplate. The keypad is seated over the PCB, wherein the PCB includes indicator lights and key input modules for the buttons. The PCB is seated over the flanged plate of the body. The faceplate, keypad, PCB and the body have a central hole for receiving the light module. The light module includes a reading light.

Abstract: A drag-reducing anticollision light for aircraft that includes a base that has convex-shaped left and right sides. A light housing that has suitable LEDs is mounted to the base, wherein the light housing is multistoried. A PC cover of an aerodynamic shape covers the light housing, and an upper base secures the PC cover to the base. Compared to conventional anticollision lights in aircraft, the anticollision light offers significantly less drag, thus saving fuel costs.

Abstract: An embodiment of an exhaust collection system for collecting exhaust from a marine vessel includes an exhaust cleaning assembly including a tank. In addition, the exhaust collection system includes a vent hood in fluid communication with the tank of the exhaust cleaning assembly. The vent hood includes a frame including one or more extendable frame members, and an outer covering that covers the frame to define an enclosure with an opening configured to receive an exhaust stack of the marine vessel therethrough, the one or more extendable frame members to extend and retract to adjust a size of the opening.

Abstract: The invention provides for a medical instrument (100, 300, 400, 500) comprising a magnetic resonance imaging system (102). The medical instrument further comprises a subject support (120) with a support surface (121) configured for supporting at least a portion of the subject within an imaging zone (108). The subject support comprises a radar array (125) embedded below the support surface. The medical instrument further comprises a radar system (124) for acquiring a radar signal (144) from the subject. The medical instrument further comprises a motion detection system (122) configured for acquiring a movement signal (146).

Abstract: Silica polyamine composites (SPC) made from silanized amorphous nano-porous silica gel and poly(allylamine) (BP-1) were functionalized with phosphorus acid using the Mannich reaction, resulting in a phosphonic acid modified composite (BPAP). Zirconium (IV) was immobilized on BPAP. Arsenate anions strongly adsorbed on the ZrBPAP composite in the pH range 2 to 8, while arsenite only adsorbed well at pH 10. Regeneration of the resin was carried out successfully for As(V) and As(III) using 2M-H2SO4. Four adsorption/desorption cycles were performed for As(V) at pH 4 without significant decrease in the uptake performance. ZrBPAP capture capacity and kinetics for arsenate were tested for longevity over 1000 cycles with only a marginal loss of performance.

Abstract: Methods of producing semiconductor materials via polymerization techniques are provided. The methods include reacting a precursor compound containing a metalloid semiconductor element, such as silicon or germanium, with a catalyst to form a polymer composition. The polymer precursor is then decomposed to form an electrically conductive hydrogenated composition containing silicon or germanium. The methods employ relatively safe raw materials and products and result in high yield reactions. Moreover, the polymers can be applied in liquid form and can be used as an “ink” or liquid to selectively coat a substrate.
