20080233551 | WIRELESS LEARNING SYSTEM - In one embodiment, the present invention provides a wireless learning system that includes a master control unit and a plurality of trigger units. Each trigger unit is able to wirelessly communicate with the master control unit and the other trigger units. Each trigger unit further includes at least one trigger switch and can provide an indication when that trigger unit is the first one of the trigger units to have its trigger switch actuated. | 09-25-2008 |
20090309307 | Toy dart assembly and method - Embodiments of the invention include a method for engaging a dart with a net. A dart is thrown toward a net. When the dart hits the net, the nose of the dart passes through an opening in the net for subsequently, lodging strands of the net in a recess situated behind the nose of the dart. Embodiments further include a recreational toy assembly having in combination a net and a dart. One or more strands of the net lodge in a recess behind the nose of the dart for coupling the dart to the net. The dart remains engaged to the net until the dart is removed from engagement with the net. For disengaging the dart from the net, the strand(s) is/are removed from the recess such that the nose of the dart may be passed out of opening in the net. The strands of the net provide the boundary or perimeter of the opening. | 12-17-2009 |
20100051777 | Collapsible Top Hanger Easel - A folding and collapsing easel that includes one or more retainer devices or attachments that can be coupled to the top of the display material. The easel includes a top portion and a bottom portion, each portion having three legs that are coupled together to form a stand. The top portion of the easel includes two elongated members that are pivotally coupled to two of the legs and further coupled to each other at adjacent ends, such that the elongated members may form a āVā shape when extended. The easel further includes one or more chart holding pins with retainer springs to secure display materials to the easel. | 03-04-2010 |
20130025045 | LAVATORY WASH STATION WITH INTEGRATED SINK AND SANITIZING HAND DRYER - A lavatory wash station includes a wash station housing, a sink basin connected to a front of the housing, wherein the sink basin has a rim, and a sanitizing hand dryer assembly having an air intake and an exit nozzle at the front of the housing. The air intake and the exit nozzle are connected by a dryer flow path and the exit nozzle is disposed at the front of the housing above the rim, where the exit nozzle provides air flow in a substantially downward vertical direction into the sink basin and the sanitizing hand dryer includes an ion generator that treats the air passing through the hand dryer. | 01-31-2013 |
20130031799 | SANITIZING HAND DRYER - A sanitizing hand dryer comprises a dryer housing having an inlet air channel and an outlet air channel. A blower draws air into the dryer housing through the inlet air channel, and directs the air out of the dryer housing through the outlet air channel A sanitizing system sanitizes the air within the inlet air channel and the air within the outlet air channel, wherein the sanitizing system within the inlet air channel includes at least one of a first air filter, a first ozone generator, a first sanitizing light source, a first photocatalytic oxidation system, a first ion generator, and a first electrostatic precipitator. The sanitizing system within the outlet air channel includes at least one of a second air filter, a second ozone generator, a second sanitizing light source, a second photocatalytic oxidation system, a second ion generator, and a second electrostatic precipitator. | 02-07-2013 |
20150361926 | INCREASED DIESEL ENGINE EFFICIENCY BY USING NITROUS OXIDE AS A FUEL ADDITIVE - A diesel engine fuel delivery system is equipped for addition of N | 12-17-2015 |
20150361930 | IMPROVED DIESEL ENGINE EFFICIENCY BY TIMING OF IGNITION AND COMBUSTION USING ULTRAVIOLET LIGHT - An exemplary embodiment of a UV light injector assembly is used to apply intense light that includes short wavelength UV to the interior of an engine cylinder near the desired time of fuel ignition. In an example embodiment, the light is produced by a short-arc xenon flash lamp. This flash lamp includes an integral reflector (e.g., a parabolic reflector) to collimate the majority of its light into parallel rays. The assembly includes a window for passing UV light into the cylinder. To direct the collimated rays of light from the flash lamp through the window a UV-transparent condensing lens is used to focus the light from the flash lamp onto the window. | 12-17-2015 |
20160032873 | REDUCING FUEL CONSUMPTION OF SPARK IGNITION ENGINES - Atomic oxygen is provided for the purpose of promoting reliable ignition and smooth combustion in a spark ignition internal combustion engine is to disperse a low concentration of an atomic oxygen precursor, such as nitrous oxide (N2O), into the flammable mixture of air and gasoline vapor prior to the time of ignition. The introduction of N2O may take place in the intake manifold, in the stream of exhaust gas being returned as part of the EGR process, or directly into the combustion chamber (for example through a small orifice in the base of the spark plug or through a small nozzle located elsewhere in the cylinder head). Introduction of N2O directly into the combustion chamber may be continuous, or it may be pulsed so as to occur at the time of or shortly before, spark ignition. | 02-04-2016 |
