Description
SYSTEM FOR DtSQUAUFYING tNTOXCATED MACHINE OPERATORS
FIELD OF THE INVENTION
The present invention relates to a system for disquafying intoxicated machine operators. More specffically the present invention relates to a system for preventing operators under the influence of alcohol or drugs from operating machines.
BACKGROUND OF THE INVENTION
Miflions of people a around the world drive motor vehicles under the to influence of alcohol and drugs. Such drivers are very dangerous on the roads and cause numerous road accidents and loss of human life. Some of the reasons that make these drivers dangerous on the roads are described as follows. Inebriated drivers' reflexes are impaired, discretion is damaged, and some feel more energetic and impulsive while the others feel more tired and slow than usual. A detection for drowsiness for a vehicle driver or machine operator is disclosed, for example, in U.S. Patent number US631 3749, wherein a vehicle driver or machine operator drowsiness monitor, configured as a self-contained module, for steering wheel or dashboard mounting, provides for individual driver/operator interrogation and response, combined with various objective sensory inputs on vehicle condition and driver control action, and translates these inputs into weighing factors to adjust a biological activity circadian rhythm reference model, in turn to provide an audio-visual drowsiness warning indication. A sobriety inter'ock of the type connectab'e to a machine such as a vehide and normaUy operating to disab'e the machine from starting unless a breath sobriety test is passed is disclosed, for example, in U.S. US491 2458.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention wi be understood and appreciated more fuy from the foUowing detaUed description, taken in conjunction with the drawings in which: Fig. I is a flow chart describing a method in accordance of the present invention for preventing operators operating machines under influence of acoho or drugs.
to Fig. 2 is a system in accordance with the preferred embodiment of the present invention for preventing operators operating machines under influence of acoho or drugs.
Fig. 3 is an exemp'ary graph describing the behavior characteristics of 4 different operators under influence of acohoI or drugs.
DETAILED DESCRIPTION OF THE PRESENT INVENTION
In accordance with some embodiments of the present invention, a reference voice of a machine operator is compared with a current voice sample of the same operator. It should be noted that term operator used throughout the specffications and claims, operates a machine. Examples of such operators are, drivers, pots, crane operators, fork lift operators and operators of sensitive systems in which a drunk/druged operator may cause harm, such as an operator positioned in a nudear station or other sensitwe facity. Examples of such machines are vehicles, aircraft, trains, watercraft, cranes etc. The embodiments of the invention are applicable to any type of machinery that the operation of which is potentiay dangerous and/or associated with high expenses.
A comparison of a reference voice samp'e with that of a current voice samp'e is made in order to find out if the operator is currently under the influence is of alcohol or drugs. A flow chart describing a method in accordance with the preferred embodiment of the present invention for preventing operators from operating a machine under the influence of alcohol or drugs is described in Fig. I to which reference is now made. At step 30 the system of the invention verifies the subscription status of an accessing operator to the system users. If a non subscribing operator has accessed, an enrollment procedure of a new operator may start, depending on the service provider's policy. The enrollment procedure starts at step 32 by first recording several voice samples of the operator when he or she is in his sober state. At step 34 the sampled voice is analyzed and the identffiers and features are extracted from the voice samples. The extracted features are used for a voice template or voiceprint which is stored at step 36 in the system's database and at step 37 the enroment procedure is terminated.
The term voiceprint used in this document is a biometric identification of person's voice, uniquely characterizing the indMdual speakers. Examples of voiceprint are disclosed in copending application Serial. No. US 200510058262 and in copending application Serial. No. US 2007/0263846.
If the operator accessing the machine is a subscriber to the system, a procedure for checking whether an operator is under influence of alcohol and/or to drugs is started. At step 38 several operator voice samples are recorded. The sampled voice is analyzed at step 40 and the identffiers and features are extracted from the voice samples. The extracted features are used for a voice template which is stored at step 42 in the system's database. The stored voiceprint of the operator in the enrollment stage and the voice print in the machine activation stage are compared at step 44. In the comparison step, several operator features are compared such as difference in speed of operator speech, difference in voice frequency and/or spectrum, difference of operator speech tone, etc. The result of this comparison is a numerical score, indicating the likelihood that the operator is under influence of alcohol or drugs. Comparing this numerical score with a threshold value, yields a binary accept/reject decision. If the operator is sober than the operator is authorized to activate machine at step 46. If the operator is not sober, such as under influence of drugs or alcohol the system of the invention can then decide at step 48 on alerting the operator or another entity such as operators' control center about his state and the machine is disabled at step 50. In some embodiments of the present invention the sobriety of the operator is sent to an operator's control center through a communications means.
It should be noted that some steps of the above described process can be combined, executed repeatedly, omitted and/or rearranged.
A system in accordance with the preferred embodiment of the present invention for preventing operators operating machines under influence of alcohol or drugs is described in Fig. 2 to which reference is now made. The system of the invention for disqualifying unfit machine operators (SDUMO) operating, to preventing their operating under the influence of alcohol or drugs 60 includes speaker 62 used in order that the operator, not shown, can hear the voice messages sent from SDUMO 60. Microphone 64 is used in order that the operator be able to send voice messages. The SDUMO further includes display 66 for displaying to the operator messages, for example messages that alert him is about his state of soberness. In some embodiments of the present invention the display is a touch screen. Voice verification subsystem (VVA) 68 includes dialogue module 70 and voice processing module (VPM) 72. The dialogue module is a set of questions or sentences sent to the operator through speaker 62 or display 64. The operator answers the question through microphone 64 and his answers are sampled and further processed in the voice processing module and compared with operator template stored in database 74. Central processor unit (CPU) 76 is used, but not limited for comparing voice parameters of accessing operator with at least stored voice parameters of same operator. The processor further used to manage database 74, control VPM 72 and display 66.
Power supply 78 s used for supplying energy to the system components.
The system of invention can also be employed in car audio/video, ceUular phones, GPS receivers and personal digital assistants (PDAs).
BENEFITS OF THE PRESENT INVENTION
The system of the present invention can detect in addition to operators who are drunk also operators who are drugged. The majority of the systems known in the art detect only one of these influences separately. The system of the present invention can detect an operator who is under influence of drugs to and/or alcohol without invading his fher privacy, i.e. there is no need for example requesting from an operator to give blood or urine in order to verify whether an operator is under influence of drugs or alcohol.
After the system of the present invention detects an operator that is drunk or drugged, the operator can not operate the relevant machine, thus is drastically reducing chances for accidents.
The method of the present invention is relative and not absolute.
Meaning, most of the devices known in the art measures the amount of alcohol in the blood of an operator. Such amounts do not necessarily indicate if the operator is drunk or sober. For example, a person with a low tolerance of alcohol will be drunk from a small amount of alcohol while an operator with a high tolerance to alcohol will remain sober with the same amount of alcohol or even much more. An exemplary graph showing the behavior of 4 operators under the influence of acoho is described in Fig. 3 to which reference is now made.
Vertica' axis 100 designates the amount of acoho dose each operator drinks.
The amount is in ascending order designated in the figure as re'ative doses DO-Dl 2. Horizonta' axis 102 designates the influenced behavior of each operator under a certain amount of a'cohoL Graphs 104,106,108,110 designate the behavior of operator A, B, C and D respectiv&y, under certain amount of acoho dosage. From the graphs it can be seen that operator A is most influenced by a'cohoL Operator A becomes inebriated from dose D3 and above. n contrast, operator B becomes inebriated from dose Dli and above. Doub'e headed arrow to 112 designates the region where the operators are ntoxicated.
