| 20100003499 | Automated layer by layer spray technology - The present invention comprises an automated apparatus capable of spray depositing polyelectrolytes via the LbL mechanism with minimal or no human interaction. In certain embodiments, the apparatus sprays atomized polyelectrolytes onto a vertically oriented substrate. To counteract the effects of irregular spray patterns, the substrate is preferably slowly rotated about a central axis. In certain embodiments, the apparatus also includes a forced pathway for the droplets, such as a pathway created by using a vacuum. In this way, a thicker or three-dimensional substrate can be coated. In certain embodiments, the apparatus is designed so as to be scalable. Thus, through the use of multiple instantiations of the apparatus, a large or irregularly shaped substrate can be coated. Rolls of textile can therefore be coated using the apparatus. Additionally, the present invention includes a method to uniformly coat a substrate, such as a hydrophobic textile material, using aqueous solutions of polyelectrolytes. | 01-07-2010 |
| 20110064936 | Method of Asymmetrically Functionalizing Porous Materials - One aspect of the invention relates to a method for installing coatings of different morphology and function within a single textile membrane. Remarkably, the methods described herein enable one to engineer the properties of a material at the nanoscopic level and produce the material in commercially viable quantities. For example, by simply controlling the flow rate of charged species passing through an electrospun material during spray-assisted Layer-by-Layer (Spray-LbL) deposition, individual fibers within the matrix can be conformally functionalized for ultra-high surface area catalysis, or bridged to form a networked sublayer with complimentary properties. | 03-17-2011 |

| 20100061097 | LED INGROUND LIGHT - Systems and devices are disclosed that can be aimed by external adjustment devices/features/means without the need to open the sealed LED module. Heat from the LEDs and/or LED mounting assembly can be transferred to the outside air while the module is tilted, e.g., up to 15 degrees, or more, from vertical. Additionally, the modular structure of the inground LED light can allow for upgrade/renewal of associated electronics with only minor disassembly. Moreover, the thermal dissipation/management afforded by the designs of embodiments can allow for an increase of the LED useful service life. The sealing of the inground light unit can preclude the chance of an end user (e.g., service technician) from causing the unit to leak and thereby cause premature failure. | 03-11-2010 |
