A multi-piece crankshaft having a shaft with two ends and in which the shaft is adapted to rotate about its shaft axis and a crankpin with at least one indentation. The housing is configured to receive an electrical device therein and has a plurality of the multiple exterior surfaces each having at least one mortise connection feature formed therein which is configured to receive a tenon associated with an accessory and to connect the accessory to the housing. When a bias voltage is applied between the drain and source with the negatively charged particles thus trapped and in-channel charged particles induced by them, the MISFET exhibits different threshold values for channel formation depending on whether it is a forward bias or a reverse bias. Also preferably, the viral vector further comprises one or more additional nucleic acid sequences encoding therapeutic substances other than PEDF. The accessory module may also be configured to include a taser andor a compact video camera. The data detection is determined in a receiver, wherein the received signal is based on a data symbol sequence angle-modulated at a transmitter and transmitted to the receiver.
