Motion control assembly with battery pack

A battery-powered motion control assembly for use with a mobile computing device, the motion control assembly comprising:

• a motion control device comprising an emission module, including an illumination source, and a detection module, including a sensor;
• a battery pack connected to the motion control device to supply power thereto, the battery pack being capable of powering the motion control device;
• a coupler electrically connecting the motion control device to the mobile computing device for at least data transmission therebetween;
• the motion control device capable of determining from an input power level to the mobile computing device from the battery pack when a low power required condition exists so that any operation needs to be a low power mode of operation;
• and
• the motion control device further
• detecting the existence of objects including objects sufficiently large to meet a threshold for reduced power consumption;
• and
• instructing at least one of the emission module and the detection module to enter a low power mode of operation upon the detection of said sufficiently large objects.
