METHOD AND APPARATUS FOR CONTROLLING VARIABLE TRANSMITTANCE GLASS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18417873 titled 'METHOD AND APPARATUS FOR CONTROLLING VARIABLE TRANSMITTANCE GLASS

Simplified Explanation

The method described in the patent application involves controlling variable transmittance glass based on the elevation angle and yaw angle of a light source, as well as the location of a target object. Here are some key points to explain the innovation:

• Obtaining elevation and yaw angles of a light source in relation to a target vehicle
• Obtaining location information of a target object within the target vehicle
• Calculating the projection area of the target object on the variable transmittance glass based on its location and the angles of the light source

Potential Applications

The technology could be used in automotive sunroofs or windows to automatically adjust the tint based on the position of the sun and other objects around the vehicle.

Problems Solved

This technology solves the problem of glare and heat from the sun by dynamically adjusting the tint of the glass to optimize visibility and comfort for the occupants of the vehicle.

Benefits

The benefits of this technology include improved visibility, reduced glare, and increased comfort for passengers in vehicles equipped with variable transmittance glass.

Potential Commercial Applications

• "Smart Tinting Glass Technology for Automotive Applications"

Possible Prior Art

There are existing technologies for automatic tinting windows, but this specific method of controlling variable transmittance glass based on the position of a light source and target object is a novel approach.

How does this technology impact energy efficiency in vehicles?

This article does not address the potential energy savings that could result from using variable transmittance glass in vehicles. By reducing the need for air conditioning to combat heat from the sun, this technology could potentially improve the overall energy efficiency of vehicles.

What are the safety implications of using this technology in vehicles?

The safety aspects of using variable transmittance glass in vehicles, such as visibility in different lighting conditions and potential distractions caused by changing tints, are not discussed in this article. Further research and testing would be needed to assess the safety implications of implementing this technology in vehicles.

Original Abstract Submitted

Embodiments of this application provide a method for controlling variable transmittance glass. The method includes: obtaining an elevation angle and a yaw angle of a light source, where the elevation angle indicates an included angle between a direction in which light of the light source is emitted to the target vehicle and a horizontal plane, and the yaw angle indicates an included angle between a connection line between a projection of the light source on the horizontal plane and a centroid of the target vehicle, and a driving direction of the target vehicle; obtaining location information of a target object; obtaining a projection area projected by the target object on the variable transmittance glass based on the location information of the target object, and the elevation angle and the yaw angle of the light source, where the target object is located in the target vehicle.
