Abstract: An electronic device includes a hand held base assembly that includes circuitry including memory and firmware executed by a processor or microcontroller of the circuitry; and a cartridge assembly that includes memory that is read by the firmware of the handheld base assembly. The cartridge assembly and the handheld base assembly are configured to removably couple together to define the electronic device for producing an aerosol for inhalation by a person. An enclosed air passageway is defined by the cartridge assembly and by the handheld base assembly, which isolates the airflow from the electronics of the device. The enclosed air passageway extends between the opening of the mouthpiece for taking a breath and a diaphragm of the handheld base assembly, movement of the diaphragm changing the air pressure within an enclosed interior space having a pressure sensor for trigging the pressure sensor when a breath is taken.

Abstract: The present invention relates to proppants which can be used to prop open subterranean formation fractions. Proppant formulations are further disclosed which use one or more proppants of the present invention. Methods to prop open subterranean formation fractions are further disclosed. In addition, other uses for the proppants of the present invention are further disclosed, as well as methods of making the proppants.

Abstract: In a method of encapsulating information in a database, a message may be partitioned into a plurality of object class entries within the database. Each of the object class entries may constitute a portion of an object class from a plurality of object classes having a given hierarchy within the database. One or more pointers may be generated; the pointers point to at least one of the plurality of object class entries. The object class entries may be stored in non-adjacent storage locations within the database, with at least one of the plurality of object class entries stored in association with the generated at least one pointer such that the at least one pointer points to a higher-level object class entry, as determined by the object class hierarchy, than the at least one object class entry stored in association with the pointer.
