A gate turn-off switch, also known as a gate-controlled switch (GCS) or gate turn-off thyristor (GTO), is similar to an SCR but can be turned off by a negative signal on the gate terminal. GTOs ...
In this paper, we present an all-optical XOR gate based on two-dimensional photonic crystals (PCs). The proposed gate is designed to be used in optical computing and all-optical logic applications, ...
The IDEM Skorpion rotary trapped key systems control access to running equipment with locks and rotary keys. To disable power to machinery and unlock a gate, the key is turned and removed from the ...
