Abacus •
An abacus is a calculator used first by the Chinese since about 500 BC, for addition, subtraction, multiplication, and division, as well as fractions and square root.
•
The inventor is unknown. However, the abacus as we know it today did not appear in China until about 1200 A.D.
•
Contests have been held between users of the Japanese abacus and an electric calculator.For addition and subtraction the abacus user was much faster than the calculator user, but for multiplication and division the advantage of the abacus was less decisively demonstrated.

BioControl Systems (BCS) • BCS development efforts utilize five different types of bioelectric signals: Electrooculogram (EOG), Electromyogram (EMG), Electroencephalogram (EEG), Electrocardiogram (EKG), and Galvanic skin response (GSR) • The essence of the biocontroller interface involves three processes: (1) bioelectric signal acquisition, (2) signal processing for pattern recognition or extraction of desired elements of the biosignal, and (3) mapping the results of the signal processing algorithm to some desired output code - which controls external electronic devices.
