  • Patent number: 7498949
    Abstract: A status information determining and outputting means updates the oldest data stored in a memory using a captured A/D value, finds a average value of six stored data items by calculation, and stores the calculated value in the memory as a current sensitivity. A status information transmitting means determines which grade of sensitivity level within a sensitivity tolerance range the current sensitivity data matches, sets a pulse spacing corresponding to the matched grade of sensitivity level, and make two pulses emit from a sensitivity data transmitting light-emitting element using the set pulse spacing.
    Type: Grant
