LiDAR is a complex technology that has gone through many adjustments and upgrades before becoming efficient and accessible for an average consumer. The bulky and expensive LiDAR has been dramatically improved as a consequence of continuous improvement. All of this was made possible via MEMS mirrors. Do you know how they can assist in lowering the cost of LiDAR?

While LiDAR systems struggled with its fundamental problems such as high cost, big size, limited edition, and low efficiency, technology has found a solution in the form of a MEMS scanning mirror.

1. What is LiDAR?

LiDAR is a light and range sensor or laser projection with distance detection. They became trendy after introducing the first uncrewed vehicles; for example, in uncrewed Yandex automobiles, the LiDAR sensor aids in orienting the vehicle in space.

The term LiDAR refers to the use of light to track the position of objects on a plane. The technology was developed in the 1960s. It was initially designed to track satellites and military targets. Later on, technology permeated other aspects of human life.

2. Key Challenges of LiDAR

Any technology sooner or later starts experiencing difficulties. LiDAR is no exception. Although, in theory, everything seems to be ideal, the reality shows that LiDAR struggles with the following issues, which limit its ability to be widely used and make it expensive:

Automated headlight control

  • It needs a mechanical mirror to deflect the laser beam;
  • Mandatory use of motor for rotation of mirror about its axis;
  • The engine consumes a significant amount of power;
  • The machine is substantial.
  • The high cost of mirrors;
  • Such an extensive system is frequently heavy and can only be integrated into large applications;
  • Many LiDAR applications necessitate a wide field of view.

3. What Are MEMS Mirrors?

MEMS (Micro-Electro-Mechanical Systems) are mechanical structures that can be miniaturized and fully integrated with electrical circuits. These microscopic electromechanical components can perform computational and communication functions while consuming very little power and tiny size.

4. Does LiDAR Work With Mirrors?

LiDAR sensors based on MEMS mirrors are a promising solution. MEMS mirrors have a well-developed silicon design that has proven to be effective in various automotive applications.

MEMS mirrors have many advantages for LiDAR, including:

No need for rotating components. As a result, the MEMS-based LiDAR system is more robust and more durable than the mechanical LiDAR system;

  • Market accessibility;
  • Compactness;
  • Small deflection angles.

A team of researchers from the University of Florida developed a prototype of the LiDAR system using the property of MEMS mirrors to deflect the laser. Not only does the novelty have a wide field of view, but it also consumes very little power. Moreover, due to its small size, it can be easily mounted in small applications.

In the LiDAR system, this feature of MEMS mirrors is used as a scanning element. As a result, the LiDAR device can be powered by a 9V battery charge. The LiDAR prototype also includes an infrared sensor, which is activated only when specific parameters are met.

The prototype has a simple design, but it is one of the bulkiest and energy-intensive components of LiDAR systems. As a result, it is ideal for residential and commercial applications that use intelligent environmental control systems. The developer team plans to improve the LiDAR system by reducing its size and power consumption.

The smaller volume and lower cost of the LiDAR will aid in its integration into a wide range of applications, such as various sensors and control systems that can display the immediate environment. We anticipate that consumer interest in future LiDAR based on MEMS scanning mirrors will increase.

7 Safety Tips for Ride-Hailing Users

Most people opt to ride-hail in the current generation because the service has proven efficient and effective in transporting people from one place to another. However, ride-hailing could incur some unwanted incidences as far as security is concerned. There have been reported abduction, rape cases, robbery, and death of ride-hailers, amongst others.

These cases are prone to occur if the ride-hailers are reluctant to verify their drivers’ identities. The latter makes it easy for the drivers to commit crimes without suspicion. Therefore, ride-hailers must be careful before boarding their rides by verifying that the ride drivers are who they expect them to be.

The following tips are essential for safety when using a ride-hailing service:

1. Check On The Reviews And Ratings Of The Ride-Hailing Company

There is usually a comment section for the users to leave behind their ride experience and ratings after every ride for most ride-hailing apps. The most reviewed and best-rated companies are sure enough to offer quality services. Over the years, there have been many companies you can choose from. Firms such as mobility SaaS Spare Labs and similar ones have made it easier for investors to develop and launch ride-hailing services.

Due to the many options available, going through the reviews provided ensures you’re requesting a reputable ride service. If the driver has many negative reviews, it’d be best to avoid that ride because you’ll most likely have the same experience.

2. Request Your Ride In A Safe Place (Preferably In Public)

In most ride-hailing apps, one can quickly identify the location of various ride drivers based on the proximity they are from your site. You can choose the driver to pick you up at your preferred location with that information. It is advisable to place a pick-up location in an open place to ensure your safety.

3. Verify With Your Rider

Asking your rider to identify you is an essential safety tip as this will help assure you if the rider is the one you were expecting. If the rider can identify you by your name, you can be confident that you are safe onboarding the ride. If the rider cannot identify you by your name, you should avoid boarding that car and communicate with the ride service provider for any suspicious acts.

Check On The Reviews And Ratings Of The Ride-Hailing Company

In most ride-hailing apps, the rides are usually identified by details such as the make of the car, the color, license plate, name, and photo of the driver. You should confirm that the information on the app matches that of the ride when it arrives.

4. Avoid Disclosing Personal Information

Avoid sharing your details with the driver at all costs. If there is a need to communicate, you should do so through the app. Desist from sharing information such as your other names, social media accounts, or physical address. It is wise to consider being dropped at a safe distance from your destination.

Thanks to technological advancements, you can make online payments. Thus, you’ll avoid disclosing personal information such as your phone number.

5. Make A Point To Inform Your Closest Associate Of Your Location

This tip will help to track your location and monitor your movement. It is a safety measure to account for your whereabouts. You can send the driver’s details to a close friend or family member to make it easy to track your ride.

It is terrible news for anyone with ill intentions to be under close watch. This is because they know that they would easily be caught if they committed a crime. If they are culprits, they will be hostile or rebel if you inform them that it is tracked. Therefore, it is wise to tell the driver that the ride is followed and observe their reactions. You can also make a call and inform your closest associate that you are now boarding the ride and you’ll be on your way.

6. Make A Wise Choice On Where To Sit

Most ride-hailing services say that sitting at the back seat enhances your safety than sitting at the co-driver seat. That is because there is a great distance between the ride-driver and the passenger. However, sitting at the co-driver seat comes in handy as it enhances a clear view of the driver and that of the path you’ll be riding on.

However, situations and vehicles may vary. It is advisable to take a seat that has a vast distance between you and the driver. Also, be cautious and consider it a warning if the driver demands that you take a specific seat.

7. Check To See That The Child Locks Are Not Engaged

When you enter the ride, please make a point of opening the door immediately after closing it. If the door does not open, make a fuss about dropping something you need to pick. Once out of the car, run to safety and request another ride.

Conclusion

There is a famous phrase that states, ‘safety first.’ Most people overlook these essential tips in guaranteeing your safety while ride-hailing. Be on the lookout for such tips next time you are ride-hailing.
