      11122,664
    • Appl. No:
      17/031011
    • Application Filed:
      September 24, 2020
    • Abstract:
      Exemplary embodiments are directed towards safety systems associated with ultra-fast fault signal pulses to increase the fault signal pulses from milliseconds to seconds to energize external devices (e.g., LED lights). This is turn will alert the operators that the system is operational or a fault was detected. The fault signal width pulses are extended to drive or trigger external devices, such as external relays, which in turn completes a circuit to energize any external devices.

    • Claim:
      1. A fault signal system comprising: a timing delay circuit; at least one delay circuit relay; a first and a second connection point; and a switch relay; wherein the first connection point is configured to connect to a device under test; wherein the at least one delay circuit relay forms a closed delay circuit when the device under test experiences a fault; wherein a default signal is provided to the switch relay when the delay circuit relay is open; wherein a delay signal is provided to the second connection point when the delay circuit relay closes.
    • Claim:
      2. The system of claim 1 , further comprising a first and a second display section, wherein the first and second display sections are coupled to the switch relay.
    • Claim:
      3. The system of claim 2 , wherein the first display section comprises a green light emitting diode (LED) and the second display section comprises a red LED.
    • Claim:
      4. The system of claim 1 , the timing delay circuit comprising a delay extender circuit comprising a delay resistor, wherein the resistance of the delay resistor determines the duration the delay circuit remains active.
