The invention relates to an applet for a mobile computing device, comprising an element to detect user input and perform appropriate associated actions, and to provide a cognitive aid for users of the mobile computing device. One such BIST includes loading microcode instructions into a main microcode sequencer and loading subroutine instructions into a subroutine microcode sequencer on the memory. A cable is connected to the load sensor for transmitting a signal representative of the amount of torque to a transmission controller. Preparations are further treated with activated bipolar chemicals to change their chemical affinity, to make them applicable to synthetic and metallic substrates and surfaces as well. A plurality of blades 32 extends across the interior 17 of the body thereby cutting a food product biased against the blades 32 into a plurality of portions. In the case where a sapphire window is used, titanium or Invar may be used for the compression material.
