Abstract: A meter value that reflects the amount of genetic material stored in a reserve is stored in a database for each reserve in a bank. Meter values allow a user to track the amount of genetic material in the reserves of a bank without needing to physically measure or disturb the reserves unnecessarily. As users withdraw and deposit genetic material from and into a reserve, the meter value is changed to reflect the change in the amount of genetic material in the reserve. In certain embodiments, the use of meter values enables accurate and instant accounting of a large number of reserves of genetic material for a large number of individuals. Users and/or individuals may be notified when a meter value falls below a threshold. Notifications may prompt a user to generate additional genetic material from biological sample or an individual to provide additional biological sample.

Based on determining that the amount of radio frequency exposure exceeds a maximum permissible exposure, the UE reduces the amount of radio frequency exposure associated with the human tissue.
