A police tester to detect the presence of a target substance includes a housing adapted to be mounted in a police cruiser; a chemical reservoir insertable into the housing; a test swipe in a disc or an automated cartridge, the test swipe adapted to receive a chemical from the chemical reservoir, the test swipe including one or more chemically treated pads; a camera to capture an image from the test swipe; a processor coupled to the camera to process the image to detect the target substance; and a transmitter coupled to the processor to transmit a test result to a remote computer at a police headquarter.

Explosive or drug detection reporting system

A portable chemical analytical apparatus to analyze a test swipe having a base; a chemically treated pad containing the swiped sample positioned in a white zone above the base; and a tab attached to one side of the base. The apparatus includes a heater to warm the test swipe to a predetermined temperature; a clamp to secure the test swipe to the heater; one or more pumps to dispense one or more chemicals onto the test swipe from a disposable cartridge; a fan to remove chemical vapors rising a predetermined distance from the test swipe; and a camera to capture an image of the test swipe for un-biased automated analysis, and displayed on an LCD screen.

Test swipe for portable explosive or drug detection system

Systems and methods are disclosed to automatically detect the presence of a substance on a test swipe by capturing a background image of the test swipe; applying one or more test chemicals to a test swipe; adjusting the temperature of the test swipe to a predetermined temperature range; controlling a variable speed fan to avoid fogging the camera's lens; capturing an in-situ image of the test swipe after the application of chemical at the predetermined temperature range; subtracting the background image from the in-situ image; generating a difference value from the two images; and searching a known database to identify the substance.

Variable fan for portable explosive or drug detection system

A portable tester to detect one or more analytes from explosives, drugs, or household chemicals, comprising: a plurality of chemical disposable, detachable reagent reservoirs storing reagents to induce a series of color reactions, wherein developed color depends on sequences of applied reagents to respective pads on a support base, reaction times and temperatures on said pad to create one or more color bar codes for a specific analyte. The tester comprises a piezoelectric dispenser coupled to each respective reservoir to dispense a mist of reagent onto respective test pads to increase sensitivity and reduce reaction heat and time; wherein piezoelectric dispenser is processor controlled to control dispensing time and volume in each step. The tester also includes a programmable digital camera system for imaging and data collection at specific times, temperature, and applied reagents for analysis by the processor, and a processor to interpret resulting changes in color codes of the test pads throughout the analysis occurring at specific times, temperature, and applied reagent and to identify or characterize the type explosive or class of explosives, clandestine drugs, or household chemicals.

Portable tester for detection explosives, drugs and chemicals based on created color bar codes for analytes

A test swipe for testing drugs, explosives or a chemical compound includes a base; and one or more swipe pads positioned on the base to receive one or more chemicals thereon, the one or more swipe pads displaying an array of colors after receiving the chemicals to uniquely identify a chemical compound.

A portable chemical analytical apparatus to analyze a test swipe includes a heater to warm the test swipe to a predetermined temperature; a clamp to secure the test swipe to the heater; one or more pumps to dispense one or more chemicals onto the test swipe from a disposable cartridge; a fan to remove chemical vapors rising a predetermined distance from the test swipe; and a camera to capture an image of the test swipe for automated analysis.

Method of analyzing a disposable test swipe

Systems and methods are disclosed to automatically detect the presence of a substance on a test swipe by capturing a background image of the test swipe; applying one or more test chemicals to a test swipe; adjusting the temperature of the test swipe to a predetermined temperature range; capturing an in-situ image of the test swipe after the application of chemical at the predetermined temperature range; subtracting the background image from the in-situ image; generating a difference value from the two images; and searching a known database to identify the substance.
