Abstract:
A process for the preparation of an antimicrobial coating solution is described. The process comprises the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating described is visible light activated. The coating is applied to surfaces and then heat treated to form a transparent layer on the surface. This is particularly advantageous where the surface is glass.
Abstract:
This present application relates generally to the science of fluid flow measurement and provides a multi-directional fluid velocity measurement device (FVMD) employing a plurality of pitot tubes arranged in a 3D configuration and extending from a spherical main body in which measurement sensors are provided.
Abstract:
Systems methods and apparatus provide a temporal analysis framework that models how the IEEE 802.11 MAC mechanism wins transmission opportunities when nodes communicate data over a plurality of communication channels. At each node, data packets transmitted by adjacent remote nodes are captured for a predetermined time interval. The capacity utilization of each adjacent node may be calculated from captured packets as the ratio of a network bandwidth used by a node for transmitting its data load and a network bandwidth available under the load conditions. Capacity utilization may be compared against a threshold parameter for determining a saturated condition. Each node communicates data representative of the saturation determination in beacon frames to one or more of the adjacent nodes, which may take preventive actions to avoid deterioration of data communications. Each network node passively monitors the performance of adjacent or “neighboring” nodes in order to detect if saturation is occurring.
Abstract:
A method for producing a multi-layer anodic coating on a metal is described. The method comprises the steps of (i) placing the metal in a first electrolytic solution and applying a current to form a first anodic layer having a barrier region; (ii) reducing the applied current to cause a reduction in thickness of the barrier region; and (iii) placing the metal in a second electrolytic solution and applying a current to form a second anodic layer.
