Abstract: A method for automatically switching a profile of a mobile phone includes measuring a current environmental noise value of ambient noise surrounding the mobile phone. The current environmental noise value is then compared to a predetermined noise value, and a noise difference is calculated. Next, the profile of the mobile phone is switched based on the value of the noise difference.

Abstract: A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.

Abstract: A universal medication port includes a cylindrical member having an internal bore with a plurality of radial passageways extending therefrom. A plunger is disposed within the internal bore of the cylinder, the plunger having an internal bore with a plurality of radial passageways extending therefrom. The plunger is movable in response to insertion of a needle-less hypodermic syringe into the internal bore of the cylindrical member so as to align the respective passageways in the plunger and the cylindrical member with one another to establish a fluid path from the syringe through the internal bore of the plunger and respective passageways in the plunger and the cylindrical member to a receptacle, such as a vial, an intravenous bottle or intravenous delivery system, in which the cylindrical member is inserted.
