摘要:
DETECTING AND IDENTIFYING MOSQUITOES CAN BE FACILITATED BY USING AN ELECTRICAL MOSQUITO DETECTOR (1) CAPABLE OF RECORDING THE SOUND GENERATED BY THE FLAPPING OF THE WINGS OF FEMALE MOSQUITO DURING FLIGHT. THIS WING BEAT FREQUENCY IS A CHARACTERISTIC OF INDIVIDUAL SPECIE OF MOSQUITO. IN THE PREFERRED EMBODIMENT, THE MOSQUITO DETECTOR (1) COMPRISES A SENSOR (10) TO DETECT WING BEAT SOUND, A BAND PASS FILTER (11) TO FILTER OUT UNWANTED SIGNALS, AN AMPLIFIER (12) WITH HIGH GAIN AND LOW NOISE, A FREQUENCY COMPARATOR (13) AND AN ANNUNCIATOR (15). WHEN THE COMPARATOR (13) DETERMINED THAT THERE IS A MATCH BETWEEN THE FILTERED SIGNAL AND THE EQUIVALENT SIGNAL FOR A CORRESPONDING WING BEAT FREQUENCY OF A FEMALE MOSQUITO, THE OUTPUT OF THE COMPARATOR TRIGGERS AN ANNUNCIATOR (15) TO PROVIDE BOTH AUDIO ALARM AND VISUAL DISPLAY OF THE SPECIE OF MOSQUITO DETECTED. THE USER CAN RESET THE ANNUNCIATOR (15) AFTER NOTING THE RESULT AND TAKE APPROPRIATE ACTIONS TO PREVENT THE MOSQUITO FROM CAUSING HARM. FIG. 1
