Abstract: A portable space heater is provided having a heating assembly that includes at least one heating element positioned in front of a fan (defined by the direction of the air flow with the air blowing toward the front) such that the heating element is in linear alignment with the fan along the axis of rotation of the fan. The fan and the at least one heating element may be further positioned within a duct assembly that narrows as it approaches a front grill of the portable space heater.

Abstract: A tower fan is provided that includes a fan body having a double cross fan blower centered in the body of the fan with a motor positioned between the fan blowers in the center of the fan body. The tower fan is capable of being oriented in both the horizontal and vertical directions. The fan body may further include first and second ends and at least two supports. At least a first support is coupled to the first end of the fan body and a second support is removably coupled to the least second end of the fan body. The first and second ends of the fan body each have a groove for each receiving at least one of the at least two support members where each groove extends entirely around the fan body. The at least two supports may both be removably coupled to the fan body or one of the at least two supports may be permanently coupled to the first end of the fan body.

Abstract: An improved fan design with an impact absorbing structure is provided. The improved fan design includes a lower fan assembly connected to an upper fan assembly using a mounting bracket. The lower fan assembly may include a fan base having multiple supporting legs which are preferably rotatably connected to the lower fan assembly. The upper fan assembly of the present invention may include a fan motor and fan blades enclosed within a protective structure. The protective structure of the present invention may preferably include an outer fan cover, a fan grille, an external cage and a perimeter shock absorbing ring extending around the circumference of the outer fan cover. The perimeter shock absorbing ring may include an inner surface, an inner absorption layer and an outer surface. The inner absorption layer may preferably include one or more flexible ribs.

Abstract: A mobile device-based human pathogen rapid response diagnostic test system providing a partially disposable test kit and a system functioning within a mobile device software application. The diagnostic test system combines surfaces chemistry, thermochemical detection and automated histological digital imaging to reduce cradle-to-grave testing time relative to the state-of-the-art PCR methods.

Abstract: The present invention provides an improved portable steam humidifier. According to a preferred embodiment, the improved humidifier of the present invention preferably includes a spiral mixing chamber connected to a steam chamber, a spiral outlet duct, an inlet duct and an outlet grill. According to a preferred embodiment, the inlet duct preferably receives air from an inlet fan and directs the air into the spiral mixing chamber where the air is mixed with water vapor from the steam chamber. According to a further preferred embodiment, the air is further directed from the spiral mixing chamber through the spiral outlet duct out through the outlet grill.
