Microwave excited ultraviolet lamp system with data logging and retrieval circuit and method

A power supply for a lamp head including a microwave excited ultraviolet lamp, the power supply comprising:

• a main control board configured to supply power to said lamp head;
• and
• a data logging and retrieval circuit operatively coupled to said lamp head and including:
• a first memory configured to store data representative of at least one of:
• a lamp head pressure and a lamp head temperature;
• a processor coupled to said first memory for periodically receiving said data representative of the at least one of:
• the lamp head pressure and the lamp head temperature;
• a first data port configured to:
• transfer data to an external device when the external device is interfaced with said first data port, and
• receive power from the external device when the power supply lacks power so that the data is transferred to the external device using the power supplied from the external device;
• a second memory for receiving the data from said first memory and for storing the data for a second time period that is longer than the first time period and that includes at least a portion of the first time period;
• the processor being coupled to said second memory for periodically transferring the data stored in said first memory to said second memory;
• a second data port configured to transfer data to the external device when the external device is interfaced with the second data port;
• a data port controller configured to manage traffic on the first data port and the second data port, wherein the data port controller, based on determining that one of the first data port and the second data port is interfaced with the external device, copies data from at least one of the first memory and the second memory to the respective one of the first data port and the second data port that is interfaced with the external device,
• wherein at least one of said first memory and said second memory is removable from said data logging and retrieval circuit;
• and
• a time keeping device operatively coupled to said first memory for providing a time stamp to the data representative of the at least one of:
• the lamp head pressure and the lamp head temperature.

A data logging and retrieval circuit for a microwave excited ultraviolet lamp system, the data logging and retrieval circuit comprising:

• a processor configured to receive data from the microwave excited ultraviolet lamp system representative of at least one of:
• a lamp head pressure and a lamp head temperature;
• a first memory operatively coupled to said processor and configured to store the data representative of the least one of:
• the lamp head pressure and the lamp head temperature for a first time period;
• a second memory operatively coupled to said processor and configured to receive the data from said first memory and to store the data for a second time period that is longer than the first time period and that includes at least a portion of the first time period;
• a first data port and a second data port operatively coupled to at least one of said first memory and said second memory;
• and
• a time keeping device operatively coupled to said first memory for providing a time stamp to the data representative of the at least one of:
• the lamp head pressure and the lamp head temperature, wherein:
• said data logging and retrieval circuit is configured to transfer the data stored in said first memory or said second memory to an external device when the external device is interfaced to said first data port or said second data port,
• said data logging and retrieval circuit is configured to receive power from the external device when the system lacks power so that the data is transferred to the external device using the power supplied from the external device,
• said data logging and retrieval circuit comprising a data port controller configured to manage traffic on the first data port and the second data port, wherein the data port controller, based on determining that one of the first data port and the second data port is interfaced with the external device, copies data from at least one of the first memory and the second memory to the respective one of the first data port and the second data port that is interfaced with the external device,
• at least one of said first memory and said second memory is removable from said data logging and retrieval circuit.
