The invention provides seed and plants of the pepper hybrid 9942815 and parents thereof. An electrical interface includes a male connector fastened at its base to one of the leads, an insulate housing having an inner contour shaped to fittedly encompass therein the male connector and at least a portion of the lead, and a cement contact that fastens the housing to the lamp exterior without air gaps. The rocking body has a plurality of depressing parts radially projecting from the center thereof, and an operating shaft projecting upwardly therefrom. A blind signal separation processor forms a mixing matrix comprising at least kN different summations of the M source signals, and separates desired source signals from the mixing matrix. The electrically powered device includes: multiple stators structured to respectively have electromagnetic coils and position sensors; a shaft fastened to the multiple stators; and multiple rotors structured to respectively have permanent magnets and arranged to rotate around the shaft; wherein the multiple rotors are connected with a driven member driven by the electrically powered device. The multi-identity security environment enables one process that is spawned by another process to access resources security accessible to the one process, as well as resources security accessible to the another process.
