Abstract
A system and method of indicating the presence of mammalian blood or other mammalian bodily fluid includes receiving ambient air at an air inlet of a hand-held sensing device and sensing a chemical component of mammalian blood or other mammalian bodily fluid in the ambient air at a sensor disposed near the air inlet of the sensing device. The system and method includes using an electronic control circuit to determine the presence of the chemical component by discriminating the chemical component of mammalian blood or other mammalian bodily fluid from other odors in the ambient air and providing an audible and/or visual and/or vibrator indication when the presence of the chemical component is determined.
Claims20
A method of indicating the presence of mammalian blood or other mammalian bodily fluid, comprising:
- receiving ambient air at an air inlet of a hand-held sensing device;
- sensing a chemical component of mammalian blood or other mammalian bodily fluid in the ambient air at a sensor disposed near the air inlet of the sensing device;
- using an electronic control circuit to determine the presence of the chemical component by discriminating the chemical component of mammalian blood or other mammalian bodily fluid from other odors in the ambient air;
- providing an audible and/or visual and/or vibrator indication when the presence of the chemical component is determined.
The method of claim 8, further comprising swinging the hand-held sensing device back and forth over the ground to expose the sensor to airborne compounds from a wounded animal being trailed.
An apparatus for indicating the presence of mammalian blood or other mammalian bodily fluid, comprising:
- an elongated housing comprising a first portion configured to be held in a person's hand and a second portion opposite the first portion having an air inlet;
- a sensor coupled to the elongated housing and configured to receive air from the air inlet;
- a control circuit coupled to the sensor, wherein the control circuit is configured to use the sensor to detect the presence of a particular chemical component that indicates the presence of mammalian blood or other mammalian bodily fluid in the vicinity of the air inlet;
- wherein the control circuit is configured to provide an audible and/or visual and/or vibrator indication when the presence of the particular chemical component is detected;
- and
- a battery configured to provide power to the control circuit.
An apparatus for indicating the presence of mammalian blood or other mammalian bodily fluid, comprising:
- an elongated housing at least two feet long comprising a first portion configured to be held in a person's hand and a second portion opposite the first portion having an air inlet;
- a sensor configured to contact air from the air inlet;
- and
- a control circuit coupled to the housing and coupled to the sensor, wherein the control circuit is configured to use the sensor to detect the presence of a chemical component that indicates the presence of mammalian blood or other mammalian bodily fluid in the vicinity of the air inlet;
- wherein the control circuit is configured to provide an indication based on detecting the presence of the chemical component.
