Methods of operating and logging the usage of a photo-thermal epilation apparatus
provide for the logging of usage information as the apparatus is employed for each
epilation session. The operational information may be applied to determine when
calibration is required, if additional usage funds must be paid before additional
sessions may be conducted, and or when and who conducted epilation sessions with
the apparatus. A usage log may be stored within a database that contains entries
of operation or usage information. Each usage log entry may include information
associated with a client, an operator, as well as other useful information related
to the usage of the apparatus. The apparatus may further be configured to communicate
with at least one remote computer. The communication with the remote computer may
be included for enabling operation and usage of the apparatus to be metered, monitored,
and or purchased in pre-determined usage allotments.
