3. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed:

FIELD OF INVENTION
The present invention relates to an improvement in or modification of the breath alcohol sensing device disclosed and claimed in Patent Application No. 859/MUM/2009. More particularly, the present invention relates to an improvement in or modification of the breath alcohol sensing device having a faster response time and better accuracy than the sensor or device disclosed and claimed in Patent Application No. 859/MUM/2009.
BACK GROUND OF THE INVENTION:
The presence of alcohol in the bloodstream impairs one's ability to operate vehicles safely and make sound judgments during driving. It has been scientifically found that alcohol was present in between 33% to 69% of fatally injured drivers and in between 8% to 29% of drivers involved in crashes that did not result into fatal injuries. It has further been experienced that young/adults with blood alcohol content greater than zero have 2.5 times the risk of crash compared to more experienced drivers. Moreover, alcohol consumption by the drivers puts pedestrians and riders of motorized two wheelers at risk.
Section 185 of the Motor Vehicles Act 1988 (India) prescribes a punishment of 6 months and/or fine of 2000 D for the first offense and a punishment of 2 years and/or fine of 3000 D for the second offense committed within three years. An amendment to this law enforced on 19 November 1994 prescribed a specified maximum of 30 mg/dL i.e. 30 mg/100 mL of alcohol detected in a test by a breath analyzer, beyond which a driver is liable to be prosecuted. However, enforcement remains a problem in India, in part due to the lack of reliable instruments in India and due to the non-availability of a proper system to efficiently prosecute such offenders due to lack of recognizable evidence. The traffic police officers in India often use portable breath-testing machines to test whether a suspected driver has a breath alcohol level above the legal limit. The reliability of such test procedures in prosecuting the regular offenders is further questionable due to corruption among

some pockets of the traffic police officers. Thus, there is a need for a system for examining and reporting the breath alcohol content of suspected drivers which does not provide any opportunity to the traffic police officer or the suspect to be misused or evaded in any manner.
The reference Reliability factor of different breath analyzers and its co-relation with blood concentration by GLC - A pilot study, IIJFMT 1(1) 2003, Raina et al, found that breath analyzers of different makers showed variation in comparison to the GLC results. The authors do not question the validity and correctness of the breath analyzers but stress the need for proper use, calibration and further studies on this subject to avoid any legal complications. The present invention meets this need in particular, among other needs described below.
An important requisite for a breath test report carried out at a road-side by a traffic police officer is that it should be capable of being exhibited as evidence in the court of law. Usually, a medical officer is also required to appear in the court of law to verify the report. Any variation in the readings from the sensing device or in the records of the traffic police officer or in the records of the police headquarters, which are usually handwritten and provide a window of opportunity of being fudged, may invalidate the report. Therefore, the strict legal scrutiny of the road-side examination conducted by a traffic police officer necessitates the need for the test report to be standardized and to be tamper proof.
Indian Patent Application No. 859/MUM/2009, filed by the instant applicant which is co-pending, discloses and claims a breath alcohol detection instrument. The disclosed instrument comprises a sampling system, a breath alcohol sensor and a display system. The sampling system is adapted to hold a received testing sample. The display system is adapted to display the breath alcohol content level received from said breath alcohol testing device. The breath alcohol sensor comprises at least a two electrode assembly and a multiple cup assembly. The two electrode assembly comprises at least one membrane electrode having catalytic material provided on at least two sides thereof.

The multiple cup assembly comprises at least an inner cup, a middle cup and an outer cup. The inner cup is adapted to hold the electrolyte and has an electrode support provided therein for supporting the membrane electrode. The middle cup is positioned surrounding the inner cup tightly and has two electrode pins disposed at the bottom portion. The electrode pins are conductively connected to top and bottom faces of the membrane electrode through two conducting leads that are capable of carrying electric current from the membrane electrodes to the electrode pins. The conducting leads are connected to the membrane electrodes at one end and are introduced within the middle cup through two leak-proof perforations provided at the middle portion of the middle cup such that the conducting leads thereby traverse through at least a portion of the middle cup prior to being connected to the electrode pins provided at the bottom portion of the middle cup. The outer cup is positioned surrounding said middle cup and has two perforations provided at the bottom portion, a gas dispensing disc and a cap fitting provided at the top portion thereof. The two perforations provided at the bottom portion of the outer cup enable the electrode pins disposed at the bottom portion of the middle cup to run through. The gas dispensing disc has a perforation provided therein so to allow a sample breath to traverse inside the sensing device. The cap fitting substantially covers the top portion of the outer cap so as to seal the sensing device in a fluid tight manner.
A need in the art remains for a system and method for examining and reporting the breath alcohol content of suspected drivers which does not provide any opportunity to the traffic police officer or the suspect to be misused or evaded in any manner. There exists a need in the art for reliable portable breath alcohol sensing system and method that is robust, leak-proof and is capable of offering consistently accurate results. The present invention meets this and other needs existing within the art.

DETAILED DESCRIPTION OF THE EMBODIMENT OF THE INVENTION:
The breath alcohol content measures the arterial blood alcohol content and is indirectly used to quantify the blood alcohol content, which determines the sobriety of an individual to drive a vehicle. The relationship between the breath alcohol content and the blood alcohol content is quantified as the apparent blood: breath ratio, which is based on the Henry's law. It has been calculated that an average venous blood: breath ratio of approximately 2300:1 applies for subjects in the post-absorptive state (range approximately equal to 1700-3000:1).
Thus, in a first aspect, the present invention provides a system for testing the breath alcohol content of an individual.
In an embodiment, the individual is a driver of an automated vehicle, who is suspected by the user of the system of the present invention to be driving under the influence of alcohol. The user of the system of the invention is typically a traffic police officer or any of his representatives designated to enforce the applicable traffic rules.
In an embodiment, the system of the present invention comprises at least one breath alcohol sensing device, at least one handheld wireless communication device, at least one printer and at least one remote storage server.
The breath alcohol sensing device of the present invention comprises at least one blowing means, at least one blow detector, at least one sampling pump, at least one alcohol sensor and at least one communication means.
According to an embodiment, the blowing means is preferably a blowing pipe or a sampling cup into which a suspected individual is requested to blow a breath sample. In an embodiment, the preferred blowing means is a blow pipe into which a suspected individual blows-in a breath sample. The blow pipe receives the

blown-in breath sample and communicates the received breath sample to a provided blow detector.
The blow detector is activated in response to the blowing effort by a suspected individual and measures the volume of breath sample that is blown-in by the suspected individual. The blowing-in of the sample breath, being greater than a minimum predetermined volume, actuates a provided sampling pump. Typically, the minimum volume of the breath sample that is required for initiating a test procedure is not critical and varies with the sensitivity of the alcohol sensor.
In a preferred embodiment, the minimum predetermined volume of the breath sample which is required to initiate a test procedure varies from about 0.8 L to about 1.2 L.
It has been frequently found that suspected individuals attempt to escape from being prosecuted by intentionally blowing in less breath sample, which therefore contains insufficient alcohol content to signal an alcohol-positive result. The present invention overcomes this deficiency by providing a blow detector that is adapted to determine whether a predetermined minimum quantity of air has been blown by the individual. In the event of a negative response by the blow detector, the system of the present invention displays a prompt requesting the suspected individual to repetitively blow into the blowing means until the predetermined minimum quantity of breath sample has been blown initiating a provided sampling pump.
The choice of a particular blow detector that is suitable in the system of the present invention is not particularly limiting. In an embodiment, the blow detector of the present invention may be any mass flow sensor-type detector that is conventionally known in the art. Preferably, the blow detector of the present invention is selected from vane meter sensor, hot wire sensor, coldwire sensor, Karman vortex sensor and membrane sensor although other sensors which may be convenient are not excluded.

In another embodiment, the blow detector is provided with a timer means, which measures the time for which an individual has blown into the blow detector. In an embodiment, the timer means is adapted to prompt the suspected individual to blow-in for a predetermined amount of time until a sufficient breath sample has been collected. The time for which a suspected individual should blow is not particularly limiting and depends largely on the sensitivity of the alcohol sensor.
In a non-limiting embodiment, the timer means of the present invention prompts an individual to blow for at least about 5 seconds. In the event that the timer means detects that the suspected individual has failed to blow-in for at least about 5 seconds, the timer means prompts the individual to blow for another 5 seconds until sufficient breath sample has been collected.
The provided sampling pump is activated when the blow detector detects that a sufficient quantity of breath sample has been collected. The sampling pump thereafter draws a predetermined volume of the collected breath sample from the blow pipe and communicates the sampled breath volume to a provided alcohol sensor.
The sampling pumps are conventionally known in the art per se. The advantage of including a sampling pump within the breath alcohol sensing device is that a fixed amount of the breath sample is exposed to alcohol sensor thereby improving the reliability and consistency of the sensing device of the present invention.
The sensing device of the present invention comprises a breath alcohol sensor. The breath alcohol sensor suitable for the present invention is the sensor as disclosed and claimed in Indian Patent Application No. 859/MUM/2009, the contents thereof being reproduced herein in its entirety.
In an embodiment, the breath alcohol sensor of the instant invention includes a single cup assembly. The single cup assembly comprises a bottom cup with grooves having sample gas inlet and/or outlet and a top cover. The provided

grooves help to disperse the gas on the electrode surface and the provided partition offers support to the current collector and the electrode. The provided top cover seals the sensor in an air tight manner.
In an embodiment, the sample gas inlet comprises at least another metal tube inserted therein to take sample from the sample path and extends up-to the sensing electrode in the sensor housing. This helps to avoid the dead volume since the tube is having very small inner diameter. This tube is inserted in the inlet tube of the sensor cup and sealed properly. The sample gas outlet tube is connected to the sampling pump via flexible tube. Grooves in the bottom cup are necessary to disperse the sampled gas uniformly on the sensing electrode surface. Partition in the bottom cup helps to give support to the current collector and the electrode. Bottom cup may have two annular rims for placement of the porous hydrophilic substrate printed on both side by using catalyst and the bare porous hydrophilic substrate (acid resistant). From the annular rim two current collector wires may be taken out and sealed them properly at the outside of the cup. The top cover of said bottom cup seals said sensing device in an air tight manner.
The electrode assembly comprises a plurality of electrodes assembled together. Preferably, the electrode assembly comprises a single porous hydrophilic substrate (acid resistant) imprinted with a catalytic material on the top and bottom faces thereof to form the sensing and counter electrodes respectively.
Preferably, the electrode porous hydrophilic substrate comprises polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) which is imprinted on the top and bottom surfaces with a catalytic material. The catalytic material may also be embedded on the said two surfaces of the membrane. The catalytic material suitable according to the present invention comprises platinum powder, one or more binders and/or one or more solvents. Alternately, other platinum group metals may also be conveniently used, which are not excluded.

The sensing electrode is the bottom surface of the electrode substrate that has been coated or imprinted or embedded with a catalytic material while the counter electrode comprises the top surface of the same electrode substrate which is also provided with a coating, imprint or embedding of the catalytic material.
The sensing electrode first comes into contact with the sample breath containing alcohol while the counter electrode, which is positioned on the electrode substrate at an opposite side to the sensing electrode, remains in contact with the bare porous hydrophilic substrate which is soaked with electrolyte.
The bottom cup comprises two electrode wires placed at the rim portion thereof. The two conducting lead wires are connected to the sensing and counter electrodes at one end through two conducting leads. Preferably, the conducting leads comprise SS wire, platinum strips connecting the sensing and counter electrodes to the electrode wires and are capable of carrying electric current between the sensing and counter electrodes to the electrode wires provided in the bottom portion of the bottom cup.
The conducting leads are preferably introduced within the bottom cup through two leak proof perforations in the rim portion of the bottom cup. These two perforations allow the electrode wires to protrude through the bottom wall of the bottom cup, which can thus be connected to an external circuit. The external circuit may be a device capable of measuring the electric current flowing through the circuit and correlating the measured electric current with the alcohol content of the sampled breath.
The electrode wires are connected to the porous hydrophilic substrate electrode through two conducting leads, which carry the electric current from the membrane electrode to the electrode wires. The conducting leads are preferably made of SS wires.
The first ends of the conducting wires are connected to the porous hydrophilic substrate electrode at its two ends, preferably on the two faces. The two faces of

the porous hydrophilic substrate electrode are the respective sensing and counter electrodes.
The second ends of the conducting wires are thereafter connected to the electrode wires at the bottom portion of the bottom cup. A substantial portion of the conducting wires is thereafter introduced within the bottom cup through leak-proof perforations situated at the rim portion of the bottom cup. The conducting wires are introduced within the bottom cup such that a major portion of the leads makes contact on the two surfaces of the electrodes placed within the bottom cup.
The cap fitting covers the top portion of the bottom cup preferably completely thus sealing the breath alcohol sensor to the external environment.
The alcohol sensor disclosed and claimed in Indian Patent Application No. 859/MUM/2009 is adapted in the sensing device of the present invention to receive a sampled volume of air from the sampling pump, to determine the breath alcohol content of the sampled breath volume as described in Indian Patent Application No. 859/MUM/2009 and communicates the determined breath alcohol content to a communication means.
The communication means provided on the sensing device connects the breath alcohol sensing device to a handheld wireless communication device. In a preferred embodiment, the communication means is a bluetooth adapter or bluetooth dongle that enables communication between the sensing device and the provided handheld wireless communication device.
The system for testing the breath alcohol content of the present invention comprises a wireless communication device. The wireless communication device, in an embodiment of the present invention, is a bluetooth enabled mobile phone.

and a printer using the bluetooth technology. Such networks are conventionally known in the art and are not intended to be particularly limiting.
The wireless communication device includes a set of programmed instructions recorded thereon for establishing network configuration between said breath alcohol sensing device, mobile communication device, printer and optionally remote storage server in accordance with a predefined protocol.
Preferably, the bluetooth protocol is a packet-based protocol with a master slave structure, wherein one master may communicate with up to seven slaves in a personal area network.

Upon successful authorization, the mobile application activates the bluetooth network and pairs the handheld wireless communication device with one or more slave devices available in the vicinity selected from the breath alcohol sensing device, wireless printer. GPS receiver which all together with the mobile communication device form a bluetooth network.
Upon successful formation of the bluetooth network, the mobile application queries the alcohol sensing device for the alcohol content in the tested individual's breath and determines whether the test result is positive or negative by comparing the received breath alcohol content with a predefined limit. In the event that the breath alcohol content is determined greater than the predefined limit, the test result is shown positive, or else it is shown negative.
In an embodiment, the mobile application prompts the user to photograph the tested individual and stores the photograph in the memory provided in the mobile communication device.
In another embodiment, the mobile application queries the paired GPS receiver for the GPS coordinates of the location at which the individual is tested and tags the received GPS coordinates with the photograph of the tested individual.

Preferably, said information includes the name of tested individual, the vehicle number being driven by the suspected individual and/or one or more identity proofs of the suspected individual including the driving license number, passport number, PAN card number or election commission card number etc.
Upon successful retrieval of the entered information, the mobile application generates a test report including a plurality of fields and prompts the user whether to save the generated report or to print the generated report. Upon receipt of appropriate input from the user, the mobile application saves the report on the mobile device, communicates the generated report to a paired printer via the

bluetooth network and simultaneously uploads the report to a central server via the mobile communication network. Preferably, the mobile communication network is the GSM network although other networks such as CDMA, TDMA. GPRS, EDGE, 2G, 3G and other wired networks are not excluded.
In an embodiment, the generated report is displayed on the screen of the mobile device, which is sent to the paired printer for printing and simultaneously uploaded to a central server. The central server is preferably located at a remote location, where it can be accessed after a successful password authentication. In an embodiment, the remote location is the traffic police headquarters, wherein the uploaded report may be tallied with the printed report and forwarded to one or more enforcement agencies for prosecuting the individual.

In an embodiment, the mobile application queries a predetermined website for the geographical name of the location corresponding to the received GPS coordinates, and upon receipt of the geographical location, includes the received geographical location into the test report.
The wireless printer is paired via bluetooth technology to the mobile communication device. It receives the test report from the mobile application and prints the report.
The printed test report is collected by the traffic police officer and the tested individual is prompted to sign the report at a provided place in the report. The

printed report is thereafter forwarded to the enforcement agencies e.g. a court of law or a magistrate via the traffic police headquarters.
In an embodiment, the mobile application includes a data storage means for storing a plurality of test reports including at least the identity of each tested individual along with the test results, date and time for upto 10000 test results. Additionally, the provided data storage means is capable of retrieving the stored information when prompted by the user.
