Gesture-based control uses sound waves to recognize movements or gestures. By sending and receiving these sound signals, a device can identify specific actions made by the user. This allows people to control the device without using their voice or hands. Such a system is useful in many situations, as it lets users operate devices discreetly. It also helps individuals with disabilities or physical challenges to interact with technology more easily. more»
A new method helps make processing video and text data easier and faster. It works by breaking down video frames into smaller pieces called patches and creating tokens for these patches. By analyzing motion information, it can identify which patches have movement and which do not. The system then removes the tokens for patches without motion, which helps reduce the amount of data the model needs to handle. This process lowers the energy and memory used while still keeping the accuracy of predictions like object detection or actions. more»
A new system uses brain signals and position data from an extended reality (XR) device to predict what will happen next in a virtual environment. It collects information about brain activity through a brain machine interface (BMI) and the device's location. Then, it calculates where the device will be in the future. Based on this prediction, it creates a pre-frame, which is a preview of the upcoming virtual experience. Finally, this pre-frame is sent back to the XR device to enhance the user's experience. more»
A surgical stapling system has two jaws that can open and close to place surgical fasteners. One jaw holds a cartridge filled with these fasteners. An electric motor helps to push the fasteners into place when the jaws are closed. The handle has a mechanism that both closes the jaws and starts the motor. A safety feature ensures that the motor only works when the jaws are fully closed, preventing accidental firing when they are open. more»
An excitation laser system operates by checking the power of its laser beam to ensure it meets a certain level. If the power is too low, the system measures the light spectrum emitted from the laser's gain medium to analyze its composition. Based on this analysis, adjustments can be made to improve the gain medium's composition. The system includes a device that captures the light spectrum and a gas supply unit that manages the gas needed for the gain medium. This setup helps maintain the laser's performance, especially in applications like extreme ultraviolet photolithography. more»
A method has been developed to help keep personal information safe in images. It starts by capturing or receiving an image. Then, it checks if there is a need to hide any personal details in that image. After that, the image is processed to remove or blur those details. Finally, the modified image can be saved or sent to others. more»
A rear lamp for a vehicle has several key components. It includes a housing that fits at the back of the vehicle and a lens that covers an opening in this housing. Inside, there is a light source that shines light, creating a holographic image when turned on. An emblem is also part of the lens, adding a decorative touch. Additionally, a bezel is placed inside the housing to support the structure. more»
Hierarchical key management helps securely transfer files between different cloud regions. It uses three types of keys: one for the original location, a temporary session key for the transfer, and another for the new location. This system ensures that each region has its own security measures in place. Additionally, different files can have their own unique keys, enhancing security further. Overall, this approach improves the safety and efficiency of moving data across cloud infrastructures. more»
