The Real Power Output Capability of a USB Port

which USB port you select on your computer and across various devices, encompassing power adapters utilized for charging. But what is the actual power that can be delivered through USB?

The current maximum attainable power output for consumer USB is 240 watts via USB PD 3.1 over USB-C. The abbreviation “PD” represents power delivery, a charging standard launched alongside the widespread use of USB-C connectors. It is fundamentally the subsequent evolution of USB, facilitating quicker and more dependable charging for high-demand devices such as contemporary smartphones and computers.

Beyond that, the output gets reduced. The highest output is 100 watts through USB-C 3.0, 15 watts through standard USB-C, and 4.5 watts through USB 3.0. The output is even lower for older standards, with USB 2.0 and USB 1.0 providing 2.5 watts or even less. Connecting a new smartphone equipped for fast charging to an older USB port or using incompatible USB cables may lead to a decrease in charging speed overall, potentially insufficient to keep up with power consumption. Devices such as the iPhone 15 and most newer smartphones necessitate USB-C Power Delivery for charging that can handle 7.5 watts or greater.

The Most Remarkable Aspect of Your Apple TV Is Not Connected to Streaming

A quick scan on Amazon reveals a variety of [accessories to enhance your Apple TV experience](https://www.bgr.com/1933478/apple-tv-accessories-on-amazon/). For example, a Bluetooth keyboard can make it quicker to search for the title of your favorite series without incessantly pressing the remote. In addition, noise-cancelling earbuds are perfect for private listening when you wish to avoid disturbing your housemates.

While external devices provide convenient enhancements, one of the most enjoyable aspects of your Apple TV comes from a built-in option: screen savers. Streaming devices and modern televisions frequently come with integrated screen savers that prevent image retention. This occurs when images become permanently displayed on the screen due to prolonged inactivity. Aside from safeguarding your display, screen savers serve as a simple method to integrate your TV into your living area seamlessly. Instead of appearing as an empty and dull black spot on the wall, your television can transform into a piece of art featuring gallery-quality visuals, a digital photo frame showcasing your cherished moments, or an exhibition of stunning landscapes and cityscapes from around the world.

For your Apple TV, you can choose from four screen saver styles: Aerials, which feature videos of scenic locations; Memories & Slideshows that display photos from your iCloud Photo Library; Portraits, which show digital clocks with your selected images in the background; or Snoopy, which includes themed videos featuring Peanuts characters Snoopy and Woodstock. The screen saver is adjustable and configurable, making it simple to tailor it to your taste. Here’s how to set up and utilize screen savers on your Apple TV.

### How to set up screen savers on your Apple TV

By default, Apple TVs come with screen savers enabled. The device will automatically rotate through all available Aerial videos after five minutes of inactivity. You can easily customize your Apple TV’s screen saver settings according to your preferences. Here’s the process:

1. Navigate to Settings.
2. Select Screen Saver.
3. Change Current Selection to the desired type of screen saver you wish to display.
4. Adjust Start After to your preferred delay period between your last interaction with the TV and the activation of the screen saver.
5. Turn off Show During Music and Podcasts to disable the screen saver while music or a podcast is playing.

You can further personalize each screen saver type directly from the Settings too:

1. Go to Settings, then Screen Saver.
2. To customize Aerials:
– Under Screen Saver Preferences, click on Aerials.
– Set the Download Frequency (how often Aerial videos are downloaded) to Daily, Weekly, Monthly, or Never.
– Choose one of the themes (Cityscape, Earth, Landscape, or Underwater) to show.
3. To customize Memories & Slideshows:
– Select Memories & Slideshows.
– Under Your Photos, click on Memories.
– Choose All Memories to include all images, or Favorites to display only your selected favorites.
– Go to Albums to select specific albums, just your favorite pictures, or your recently shared album.
– Under Other, select Music Albums to utilize album art from your Apple Music library.
– Whenever available, go to Style and choose your preferred transition style.
4. To customize Portraits:
– Press Portraits.
– Select which options (People, Pets, Nature, and Cities) to include.
– Adjust the update frequency to your desired time interval for portrait transitions.

Remember that for Memories & Slideshows and Portraits, you need to set up iCloud Photos on your Apple TV first.

### How to control your Apple TV screen saver

While you can determine the inactivity period before the Apple TV screen saver activates, you also have the option to manually turn it on. This is one of the

The Requirement for an Additional Traffic Signal in the Age of Robotaxis and Autonomous Vehicles

Waymo is already employing self-driving vehicles, and you can now experience a ride in a robotaxi in various cities across the U.S. The roadway infrastructure may require modifications to accommodate the increasing number of autonomous vehicles (AVs) anticipated in the coming years. A group of transportation engineers at North Carolina State University has been focused on one component of this infrastructure since 2020: incorporating a fourth traffic signal, which they propose could be white (although it could actually be any new hue).

When the white traffic signal activates, human drivers will understand that they need to perform a single action: Follow the vehicle in front and mimic its movements until the signal changes. This concept arises from the capability of AVs to interact with one another as well as with traffic signals. The white signal would illuminate only if a sufficient number of AVs are present at a busy intersection. When a human-operated vehicle reaches the intersection, it would adhere to the actions of the AVs. Drivers would continue to obey conventional traffic light regulations until the fourth signal activates, but if a certain threshold of human-operated vehicles is present at the intersection, they would revert to the traditional traffic light system.

The underlying idea is that AVs linked to a smart traffic light could enhance traffic flow and diminish fuel consumption. The initial proposal suggested a single computing system to gather data regarding the quantity of AVs nearby, in conjunction with managing traffic at the intersection. In 2023, the researchers introduced a new distributed computing system.
