Inexpensive, and easy to use self cleaning mixtures that use photoactive agents such as titanium dioxide(TiO.sub.2) and tungsten oxide(WO.sub.3) along with mixing the agents with co-catalysts such as carbon(C), Fe(iron), Cu(copper), Ni(nickel) and CO.sub.2 P. In addition, the co-catalyst loading can include up to approximately 5% carbon to maximize the inhibiting algae growth. The mixtures can be used to inhibit various growth organisms such as but not limited to algae, fungus, bacteria and mold...

A device for both warming substances and for providing a nightlight. The device can have a single opening in a upper lid portion for allowing various sized containers of substances to be inserted therein. The substances can include lotions, creams, pastes, gels, liquids, and the like. Controls such as rheostats can be adjusted to select desired nightlight intensity levels and desired temperature levels. Timers can adjust when the rheostat settings are to be turned on and off. Visual and/or audib...

Detachable bottle and food holding subtrays and clamps for attaching onto the raised ridge edges on trays used in highchairs, strollers, booster chairs, and activity chairs. The clamps can be a single component having a curved upper flange for fitting about the raised ridge of the existing tray, and an upper bent flange having an end which abuts against a lower surface of the tray. Dual cylindrical bottle subtray holders and flat planar food subtray holders can snap onto the clamp leaving the bo...

A device for isolating dryer exhaust lines. The device can be attached between a dryer exhaust and an exterior dryer vent. The device has a door that slides between an upper position allowing the air passage duct between the dryer exhaust and the exterior vent to be open and a closed position which closes the air passage duct. A rod slidable within eye type slits has a handle at one end and is attached to the sliding door at the opposite end. A user can push the rod downward which slides the doo...

A method and apparatus using the worldwide web portal site to provide, publish and maintain a database for missing/stolen items and missing persons/fugitives. The method and apparatus further utilize this database as a backbone for an internet portal, providing for automated contact of interested parties, automated e-commerce for replacement of assets, and immediate distribution of published information. The invention allows for extracting information from entered police reports to create an all...

A dual-purpose device that can be used to both carry a pair of skis and be used to lock skis. The device has a main line with looped ends, and a second line attached to a midsection of the main line having one exterior looped end. One of the looped ends of the main line is slipped over a pair of skis behind a foot support, and second line is wrapped about the skis and the other looped end of the main line is passed through the second line exterior loop, and can be draped over a shoulder of a use...

An attachable and detachable wheelchair tray with an adjustable work surface is disclosed. The adjustable work surface has two parts connected with a hinge. Part one is a horizontal stationary supporting base and part two is a movable top portion which can be tilted in an angular range of from 90 degrees to 180 degrees in relationship to the horizontal base. There is also an extendible auxiliary supporting rack attached to the movable top portion that allows the user to enlarge or reduce the wor...

The eye-tracking system is based on the reflection of four light emitting diodes (LED)s at the cornea of user's eve. The LEDs emit infrared light at 900 nanometers and the virtual images formed behind the cornea as well as a near infrared image of the pupil are displayed on a charged couple device (CCD) sensor. The optical system used to display virtual environments is also used to conjugate the virtual images of the LEDs to the CCD sensor. This optimizes the integration of eyetracking system in...

A useful optical device to provide continuously variable rotation of polarization of linearly polarized light in a wavelength-independent manner. This device features a cell of twisted nematic liquid crystal sandwiched between an input window and a rotatable output window, both with surfaces prepared so as to orient the nematic liquid crystal molecules. This optical device has different applications such as: variable-angle polarization rotator; using broad band polarizers as an energy attenuator...
