A pivotable andor flexible razor cartridge is provided. During the shorted mode of operation, a pair of electrical contacts extend from the cam housing to operably engage the electrical contacts electrically connected to a energy storage device such as a capacitor, while the electrical contacts are retracted and rotated within the cam housing during the open mode of operation. The optical coupler may be fabricated using wafer polishing technology or grayscale photolithography. The cluster model is updated from the database records brought into the rapid access memory.
