Abstract: In some implementations, a computer system may initiate a method comprising: the method comprising: initiating communication between a tag and a reader; initiating a first program; determining a communication time period by starting a timer when the tag and the reader are within a communication range and stopping the timer when the tag and the reader are no longer within the communication range; comparing the communication time period to a first threshold time period; and when the communication time is greater than the first threshold time period, initiating a second program different from the first program.

Abstract: A mobile computing device includes: a battery compartment configured to removably secure a first battery pack; an output device; and a processor configured to: detect a second battery pack in proximity to the mobile computing device; responsive to detecting the second battery pack, place the mobile computing device in a low-power operational mode; control the output device to generate a battery swap readiness notification; and responsive to securing of the second battery pack in the battery compartment in place of the first battery pack, return the mobile computing device to a full-power operational mode.
