A telecommunication control method for a heterogeneous network is provided. The liquid discharge method includes setting an arrangement pattern according to shapes and positions of the target discharge partitioned areas so that a number of the discharge nozzles selected to be used among the discharge nozzles capable of depositing the liquid in the target discharge partitioned areas is the same in each discharge timing. The electrical power generation unit includes a fraction alternator and a head-end-power alternator. A base mechanically and electrically connects at least the discharge tube arrangement in the outer envelope to a lamp-holder. Other embodiments are described and shown. Suitably, the devices are automated devices which require little if any operator intervention or sample handling, thereby reducing contamination, improving success rates and increasing efficiency.
