Patenting Life Saving DUI Technology

Drunk driving remains one of the leading causes of death among American adults and children; yet technology exists which could save lives.

DUI technology refers to the development and implementation of various technological advancements aimed at addressing and combating driving under the influence (DUI) offenses. DUI technology encompasses a wide range of tools, systems, and devices designed to prevent, detect, and deter individuals from operating a vehicle while impaired by alcohol or drugs.

When these technologies are invented, they must be patented. However, patentable inventions must fulfill certain criteria. They must involve an inventive step, be capable of industrial application and bring value to someone.

Ignition Interlock Devices

Ignition interlock devices are mandatory for anyone convicted of driving under the influence (DUI) of alcohol or drugs, preventing anyone with blood alcohol concentration of 0.02% or above from starting their vehicle and starting the ignition.

These devices, also referred to as breathalyzers, use breath samples taken from drivers to measure their Blood Alcohol Content level and must be installed in your car prior to driving again. A test must first be passed before continuing.

If your initial breath test fails, if necessary a rolling retest may be conducted at any point during your journey – you won’t know exactly when this will occur.

As part of the rolling retest, it is strictly prohibited for you to start your car; rather, you must pull over to the side of the road and breathe into a tube at a designated area on either side. Once completed, the device will record your results and submit them electronically back to your provider.

One downside of these devices is their susceptibility to being falsified by other individuals who try to blow into them; you should take steps to avoid doing this as doing so may lead to charges of DUI in Pennsylvania.

Tracking when to submit breath samples may also be difficult – particularly when in public settings. To help make things simpler, the system will send text or email notifications whenever it needs another one of your breath samples.

Ignition interlocks can also be programmed to conduct random retests at specific intervals – say every 30 minutes. These random tests give drivers time to pull over, perform the test, and resume their journey without incurring additional penalties.

In case of failure during a running retest, your device’s horn or lights will honk or flash to inform law enforcement of its presence and warn them. However, this can be dangerous as your car won’t stop and it could prevent you from calling for help when needed.

To address these problems, the present invention combines facial biometrics and ignition interlocks in order to permit drivers subject to court-ordered supervision to operate their vehicles while adhering to DUI restrictions. It includes a mechanical device for detecting an infrared scan of operator faces when sitting in vehicle; data processor that stores and controls facial biometrics; two-way communication component transmitting results back to service monitoring centers for reporting.


Breathalyzers are one of the key tools in identifying blood alcohol content (BAC), an essential measure in DUI cases. Law enforcement often use them as field sobriety tests or evidence collecting devices at point-of-arrest.

These devices employ breath analysis technology that detects when alcohol in the air evaporates into alveoli – tiny air sacs in your lungs containing microscopic air sacs – in your lungs, directly correlated with your blood alcohol content (BAC), enabling estimation via various means.

Some breathalyzers rely on the color change of a solution of potassium dichromate when you exhale, moving from red-orange to green as your breath evaporates and alcohol presence in the breath increases. This allows it to measure how much ethanol there is without having to sample your blood with needle or syringe.

Portable breath testers (PBTs), designed specifically to be carried around on police officers’ belts, allow quick and simple on-the-spot analysis of an individual’s blood alcohol concentration level (BAC) by collecting samples of their breath as they blow into a mouthpiece and sending it directly into a device.

If a police officer administers the breath test incorrectly or a subject has any substances in their mouth that could alter results, inaccurate readings could occur and lead to false positive results that result in DUI charges being laid against them.

Ignition Interlock Devices use breathalyzer technology to test drivers for alcohol before beginning their engine. Approved by the National Highway Traffic Safety Administration (NHTSA), such devices may be required following a conviction for impaired driving.

Patenting these devices has made it easier for law enforcement agencies to detect drivers under the influence of alcohol, leading to decreased DUI-related deaths and injuries and creating changes to laws regarding drunk driving restrictions across North America.

Alcohol Sensors

Drunk driving is the leading cause of fatal road accidents. By mandating technology into all new cars by 2024, new technology would help deter drunk drivers from operating vehicles, thus decreasing drunk driving incidents and accidents.

Alcohol sensors that monitor a driver’s blood alcohol concentration (BAC) could become one of the most promising DUI lifesaving technologies over the coming years. They could be installed in every vehicle on the road to deter people from driving while impaired, and assist police in apprehending those driving impaired.

These devices work by employing a sensor to measure both alcohol molecules in a driver’s breath and carbon dioxide exhaled from them, with this sensor placed near them but in an unobtrusive location so it does not impede with car operation.

The system could also be used to keep intoxicated individuals from driving cars with sensors on them; should one attempt to drive, the sensors would immediately shut off and stop him or her.

There are various alcohol detection devices on the market today. Some devices utilize finger sensors to assess BAC levels while others work by sampling air from specific locations or parts of a person’s body.

These devices could eventually be integrated with apps that send alerts directly to a driver’s phone or alert the police electronically when someone suspected of drinking and driving is detected. Although such technologies aren’t foolproof and sometimes require human interaction to function effectively, they remain an integral part of fighting drunk driving.

Researchers are exploring various methods for detecting alcohol consumption within drivers’ bodies, including sniffers that detect its smell and skin sensors that measure how much has been absorbed by their bodies.

Most promising technologies include those that can be integrated with an app to notify drivers if their blood alcohol concentration exceeds certain limits, thereby saving countless lives over time. Such technologies should become increasingly mainstream over the next several years and could save many more lives than otherwise possible.

Driver Monitoring Systems

Driver monitoring systems monitor drivers to detect when their attention wanders from the road and alert them if their eyes wander off of it, their head nods forward, or they appear drowsy. Driver monitoring systems can also detect when drivers engage in activities that divert their focus away from driving such as talking on cell phones or engaging in other distractions that divert it.

Driver monitoring systems could play a vital role in helping prevent accidents that would have otherwise resulted in death or severe injury, helping reduce fatal crashes caused by distraction and fatigue. These systems could make an invaluable contribution toward eliminating road deaths.

Driver monitoring systems are safety features that use cameras and sensors to assess driver attentiveness. They can alert the driver to their level of vigilance or initiate intervention if their attention lapses too frequently.

Consumer Reports notes that this technology makes an excellent complement for partially automated vehicles such as those equipped with adaptive cruise control or lane centering features, helping prevent drivers who are fatigued from abusing these assistance features and remaining focused on driving their vehicle and staying alert on the road.

One key component of a driver monitoring system is an infrared camera capable of tracking eye and facial movement, providing information that identifies each driver and provides audio and visual alerts when they stop paying attention.

Soon to hit the market and an integral component of many cars, partially automated vehicles require drivers to reengage and prepare for certain functions, such as controlling their car when it detects an impending collision. With such systems becoming more widespread soon enough, their importance becomes ever more obvious.

Driver monitoring systems can be patented as technologies. Their versatility enables them to serve various functions – protecting the environment and saving lives on the roads are among them.

These systems not only prevent drowsy or distracted driving, but can also help decrease the risk of accidents caused by medical issues, fatigue or intoxication – as well as help avert crashes and save hospitals money in the process.

Use of Smartphone Apps

Smartphone apps have emerged as a powerful tool in the realm of DUI technology, offering innovative solutions to combat impaired driving. These apps leverage the capabilities of smartphones, such as sensors and algorithms, to provide users with valuable information and tools related to assessing and preventing impaired driving.

One way smartphone apps contribute to DUI technology is by providing educational resources and raising awareness about the dangers of driving under the influence. These apps offer informative content, statistics, and interactive features that help users understand the impact of impaired driving on themselves and others. They may include visual simulations, quizzes, or interactive games that demonstrate the effects of alcohol or drugs on driving performance, serving as a preventive measure by promoting responsible decision-making.

Moreover, some smartphone apps utilize the built-in sensors, such as accelerometers and gyroscopes, to estimate a user’s level of impairment. These apps employ algorithms that analyze data from the sensors to assess factors like balance, coordination, and reaction times. By comparing the user’s performance against baseline measurements, these apps can provide a rough estimation of impairment levels. While they are not as accurate as official testing methods, they can serve as a reminder of the potential risks associated with driving under the influence.

Additionally, some apps offer features that enable users to connect with designated drivers or ride-sharing services, promoting alternative transportation options and reducing the likelihood of impaired individuals getting behind the wheel. These apps may provide quick access to taxi services, ride-sharing platforms, or designated driver networks, helping users make responsible choices when they are not fit to drive.

While smartphone apps cannot replace official testing methods or ignition interlock devices, they serve as valuable tools in the DUI technology landscape. By leveraging the widespread use of smartphones and their capabilities, these apps contribute to the overall goal of preventing impaired driving, raising awareness, and providing users with resources to make informed decisions and prioritize road safety.
