Methods, systems and devices for a waveguide pumping gain guided index antiguided fiber laser having a fiber selected for a refractive index crossover at a wavelength between a pump wavelength and a laser emission wavelength. A waveguide pumping system pumps a light having a pump wavelength into the fiber allowing a laser light to be captured by a gain guided process in the core while the pump light, propagating in the cladding is coupled to the core. The fiber selection includes selecting a fiber with a cladding material having a refractive index less than a core material refractive index for …

A disposable microsensor is designed, fabricated and tested for standard BOD (Biochemical Oxygen Demand) measurements. A transparent Cyclic Olefin Copolymer COC) substrate is used for sensor fabrication. Standard lithographic procedures in addition to techniques like screen printing and electroplating are used to fabricate the sensor. A microbial strain of Trichosporon Cutaneum is immobilized over one pair of sensor electrodes while the other is used as a reference. Depending on the respiratory activities of the microbial strain in different samples, the BOD values of the samples can be measured in terms of difference between the output signals. The sensor layer is …

High Efficiency Solar Power Fan, Danny Parker, Bart Hibbs
UCF Patents
Highly efficient ventilation fans for exhausting air out from underneath roofs, and/or for being portable in use and application. The fan can include optimized airflow blades having a twisted configuration that can move at a rotational speed operation of up to approximately 500 rpm. The approximately 15 inch diameter twisted blades can be premolded on a hub that together form a single molded unit of plastic. They can also be fabricated using metal. The unit can be mounted in an exhaust outlet having a conical diffuser on or adjacent to a roof. Alternatively, the fan can be portable for use …

Carbon Nanotube Reinforced Metal Composites, Quanfang Chen
UCF Patents
A carbon nanotube reinforced metal nanocomposite material includes a continuous metal phase, and a pluarlity of carbon nanotubes dispersed in the continuous metal phase. The metal phase extends throughout substantially an entire thickness of the nanocomposite material. The nanotubes are preferably single wall nanotubes (SWNTs). Carbon nanortube reinforced metal nanocomposites according to the invention provide thermal conductivity and electrical conductivity which are generally significantly higher than the pure metal continuous phase material, mechanical strength is 2 to 3 times greater than that of pure metal, and a tailorable coefficient of thermal expansion obtainable through changing the percentage of nanotubes in …

Method Of Applying Photocatalysts To Thermoplastic Surfaces, Clovis Linkous
UCF Patents
Thermoplastic surface modification is achieved with photocatalysts, such as titanium dioxide, tungsten oxide and mixtures thereof. A uniform coating of a powdered photocatalyst is applied to a thermoplastic surface that is wetted with an organic solvent. The coating is in a range between approximateiy 1.5 mg/cm2 to approximately 2.5 mglcm2. After the uniform coating of photocatalyst is dried, the thermoplastic surface is heated to a temperature above its softening temperature, usually in a range between approximately 80°C to approximately 130 OC; then, a mild pressure is applied to imbed the photocatalyst into the surface of the thermoplastic sheet. The method …

Orthogonal Frequency Coding For Surface Acoustic Wave Communication, Tag And Sensor Applications, Donald Malocha, Derek Puccio
UCF Patents
A secure apparatus, system, device and method for coding surface acoustic wave identification tags and sensors to enable unique sensor operation and identification for a multi-sensor environment. In an embodiment, a pseudo noise sequence is applied to the orthogonally coded signal for increased security. An orthogonal frequency coding technique is applied to the SAW tag using periodic reflector gratings for responding to an orthogonal interrogation signal to transmit the sensor identification and sensed data. A transceiver interrogates the sensor with a stepped up chirp corresponding to the orthogonal frequency coded chip frequency response, receives a response from the SAW device, …
