Example embodiments for configuring a serial non-volatile memory device for an execute-in-place mode may comprise a non-volatile configuration register to store an execute-in-place mode value that may be read at least in part in response to power being applied to the memory device. Additionally, circuitry is provided to assist in balancing batteries used in a string of multiple batteries. This can be achieved by a pulsed onoff modulation in which the first relaxation minimum of a currently emitted pulse coincides in the light source with the first relaxation maximum of a reflected pulse. The anchor member can be a substantially flat piece of plastic having a central opening for closely receiving the dirty air outlet nozzle on the vacuum cleaner. This is accomplished by apply manual pressure to a slidable component of the flag pin that raises a dome shaped ejector component positioned within the hole-cup thereby ejecting the golf balls contained therein, which also prevents balls from falling back into the cup.
