Active Noise cancellation (ANC) is a process that eliminates unwanted environmental audio by identifying unwanted sound waves and creating precisely inverted signals to neutralize the original sound, thereby reducing distracting background noise to the greatest possible extent.
ANC is the most known type of noise cancellation and has mostly been used in over-ear headphones. This technology has become so small and battery efficient, as now it can be used in true wireless in-ear earphones.
The system is based on microphones that “listen” to the sounds outside and inside of the earphone, an ANC chipset inverting the soundwaves, and a speaker inside the earphone canceling the outside sound by the neutralizing soundwaves.
As of now, Huawei launched a number of wearables equipped with Active Noise Cancellation technology to offer the optimal noise-reducing performance. The list of product includes:
Moreover, Huawei FreeBuds Pro delivers the best noise-canceling performance yet on a Huawei audio product with an industry-leading noise cancellation rating of 40dB.
Active Noise Cancellation (ANC) modes:
Smart Dynamic Mode: The earphones automatically adjust the appropriate noise reduction mode based on external noise.
Cozy Mode: In a quiet environment like libraries, this feature helps you reduce the noise of air conditions, computers, and other machines to the right degree of noise reduction, which comfortable and natural.
Standard Mode: When you in the street or cafe and want to stay away from the noise and immerse yourself in music and games, this is a perfect mode for an improved user experience.
Ultra Mode: While taking a flight or subway, this feature effectively reduces the heavy low-frequency noise and allows you to enjoy peace and quiet.
Huawei smart car tech can measure water accumulation to avoid incidents
On the 23rd of July 2021, Huawei released a new patent for determining the depth of inert water, which was applied by the company on the 3rd of March this year. This new patent will be proved another significant step towards the company’s strategy of making more advanced smart vehicles.
This new patent is entitled the “method and device for determining the depth of inert water” has the publication number CN113168535A. It is designed to identify the depth of the water accumulation area to avoid any possible mishappening.
Although, the automotive industry has developed many advanced technologies, which brings extra convivence for the users. But, when it comes to crossing through water accumulated areas, only the driver’s knowledge is considered to be safe.
To reduce any vulnerability in the water accumulated area, Huawei introduced this new technology. As per the patent description, this method will follow the below-mentioned procedure to gain the desired result-
- First, capture the images of the present inert water road
- Then, analyzes the image to extract valuable information
- Now, obtain the spatial location of the edge of the inert water
- Afterward, obtain the road slope angle
- Thereafter, determines the inert water and road position corresponding to the maximum water depth of the area using the recommended algorithms
Hence, the spatial location, road slope angle, and position, maximum water depth, and maximum inert water depth are determined.
The Huawei inert water patent method will specifically provide help for the autonomous driving system and contributes to more enhanced in-vehicle capabilities. Furthermore, it’ll cover the internet of vehicles that includes-
- V2X: vehicle outreach
- LTE-V: long-term evolution of vehicle communication technology
- V2V: Vehicle-Vehicle
Huawei autonomous driving control solution with identified signals
Last January, Huawei applied for a new patent for a driving controlling method in smart cars, devices, and related equipment, which was published on July 23 with announcement number CN113160590A in China.
For a long time, Huawei is securing its new ideas, methods, and technologies mainly related to smart cars in the form of patents. The Chinese tech giant’s new aim is to become a leading technology supplier in the automobile industry.
According to the patent document, this method of driving controlling method of the smart car according to the detected signal recognition to improve the safety.
Let’s take a look over the patent method for controlling driving of the smart car:
- When the controller first recognizes the signal display device and calculates the target value of the acquisition parameter of the image acquisition device in the smart car.
- The acquisition parameter of the image acquisition device is used to indicate the acquisition period and warm light to collect the image the number of times, exposure duration, and interval duration.
- After that, it sends an instruction to the image acquisition device and adjusts the acquisition parameters.
- According to the image acquisition device to obtain the image identification signal identification, and control the smart car to drive according to the identified signal identification.
In this way, the probability that the signal identification in the image collected by the image acquisition device is in the complete state is increased.
Also, the probability that the result recognized by the controller according to the image is consistent with the new result of the actual signal identification table. As a result, it improves the identification of smart car control accuracy and safety.
Huawei has a new emergency calling feature with intelligent number selection
At the beginning of 2020, Huawei has developed a method and electronic device for emergency calls and filled the patent registration to secure this innovation. This method aims to quickly help the users in emergency situations.
According to the China Intellectual Property database, this patent was published on July 23, 2021, with announcement number CN113163052A in China.
The patent application describes that an emergency call method, which is applied to the electronic device (mobile phone). However, the patent method working includes:
When the mobile phone is in a locked state, the first operation of the user is detected on the display screen. In response to the first operation, the phone displays the emergency call interface through the display screen.
The emergency call includes one or more emergency call numbers and after the first preset time period expires. It automatically makes a call to the first emergency number, and the one or more emergency numbers include the first emergency call number.
After the first preset time period expires, if the mobile phone does not detect the user’s operation on the display screen, it will automatically alert after the call is disconnected between the mobile phone and the alarm station.
The smartphone displays a lock screen interface through the display screen. The realization of the present application helps a user to quickly initiate an emergency call in an emergency situation.
Importance of emergency call:
The emergency call is a very useful feature for asking for help through the mobile phone when you are in danger, in critical or emergency conditions.
In emergency situations such as emergency medical assistance, traffic accidents and natural disasters, the importance of emergency calls is increasing, and the laws and regulations of various countries have created a constant requirement for emergency calls.
