For example, if the data on the connected personal computer is inadvertently deleted or damaged, it can be

restored from the USB memory stick or downloaded from the internal SD card. Or, if the USB memory stick is

not available, it can be downloaded in the field and restored from the iBall Instrument’s Data Server Center.

It NOTE: The Bloodhound stores all job data to the internal SD storage media every 6 seconds. This SD card

can be found on the Brain board. It is a common camera type storage card and can be picked up just about

any electronics store. The Bloodhound comes with a 2 gigabyte storage. Typical storage size is about 500

Kilobytes of information a day. The collected Bloodhound data is primarily stored on this SD card. If a user

has a compatible USB memory stick installed in the Bloodhound USB front panel, the Bloodhound attempts to

also place data onto the memory stick, after it detects it.

It should be noted that a host personal computer is not required to use this equipment on a site that is

monitored only.

Further, the Bloodhound always operates in full range. No more data losses due to not having the correct

settings on the instruments. There are no settings to make or dilution valves to adjust. Further, the

Bloodhound Gas Detection System uses the most advanced Infrared sensor for the best accuracy and

longevity.

All connections to the equipment are made on the side of the case and all access controls are environmentally

protected within the case or can be locked to prevent tampering.

The Bloodhound uses fifth generation high-speed Infrared sensors for hydrocarbon detection as well as new

advanced custom materials used in the high-density packed chromatograph column for better separation of

sampled gases.

The equipment is set up to monitor and sense Methane and like type hydrocarbon based gasses, Oxygen,

Hydrogen Sulfide, and Carbon Dioxide.

2. BLOODHOUND DETECTION SYSTEM

A. Infrared Detector System

Currently most gas detection systems deployed in the exploration industry utilize either a hot-wire or a hot-

wire/TCD system. These types of hydrocarbon detection systems have been in operation for many decades

and are still in widespread use today. A simple linear calibration was easily possible both mechanically and

electrically.

An industry standard calibration technique calls for injecting a known percentage of methane gas, typically 1%,

into a hot-wire system. Because a hot-wire system is generally linear over its usable range, a known linear

scale for the hot-wire can be calculated using zero and a single-point of calibration. A third point of calibration

is sometimes employed to calibrate the high end scale utilizing 100% methane. This second point of

calibration is generally used on TCD type detectors in order to locate the point to where 100% of injected

methane is detected as raw natural gas, which is usually mostly methane.

Generally a system is deployed to allow the hot-wire and TCD to operate together and hand off the detection

duties as the concentrations change from low ranges to high ranges. Sometimes the system utilizes a type of

air dilution to keep the hot-wire from saturating and causing damage to the burning sensor if the concentration

gets above 5% in air.

Today’s infrared detectors have been shown to react to hydrocarbon based gases from zero to 100% in

concentration without air dilution. This feature garnered great interest within the petroleum geological

community as the benefits of infrared over the traditional hot-wire systems became obvious.

When the same hot-wire calibration technique was used to calibrate an infrared detector, problems were

quickly discovered because the overall output of the infrared detector is not linear. This linear calibration of a
