A system and method are disclosed for configurable application access control. An application-access-control element is presented on a computing device and associated with a protected application. Upon activation, a challenge-logic engine presents at least one authentication challenge and evaluates a user response against a correctness criterion.

This application discloses a power input protection circuit, an automotive wiring harness, and an automotive system, relating to the field of automotive systems. Addressing the problem that current protection circuits directly cut off voltage output upon triggering protection actions, this application provides a power input protection circuit including multiple voltage-limiting protection circuits. Each voltage-limiting protection circuit can reduce the power input voltage to prevent damage to downstream loads when the power input signal exceeds a protection threshold due to voltage fluctuations. This voltage-limiting protection method ensures that the load can still receive power input, thereby guaranteeing the normal operation of the load equipment and not affecting the user experience. Furthermore, multiple voltage-limiting protection circuits correspond to different protection voltage ranges and different target voltage values, ensuring that regardless of the voltage value of the power input signal, there is always a suitable voltage-limiting protection circuit that can effectively limit its voltage, guaranteeing that the power supply voltage output to the load is not excessive and could damage the load equipment.

This application relates to triggering a refresh of non-volatile memory. A host system can communicate with a memory system, wherein the host system and the memory system may be contained within a vehicle (e.g., an automotive system). The host system can receive an indication that the vehicle is powered off and can enter a power-off state in response to the indication. The host system can detect a trigger event (e.g., usage time or temperature input) that switches back to a power-on state when the vehicle is powered off, the trigger event being associated with performing a refresh operation at the memory system. The host system can enter the power-on state and send a power-on command to the memory system. The memory system can perform the refresh operation on one or more memory cells while the vehicle remains in a power-off state.

In various scenarios such as industrial control, IoT, smart homes, and automotive systems, systems need to determine whether to respond to input information based on context. For example, when industrial sensors periodically report non-urgent data, the control system can remain silent to save computing power; a smart light bulb silently responds to a "turn on the light" command when it senses sufficient light during the day. However, existing technologies suffer from fixed response strategies, lack of learning ability, insufficient scene awareness, and resource waste. This application provides a context-aware interactive silent method, system, and computer-readable storage medium, aiming to solve the problems of fixed response strategies, lack of learning ability, and insufficient scene awareness in existing systems. It enables the system to dynamically decide whether to silently process input information based on its importance, processing capacity, and operating scenario, and to continuously optimize through feedback learning.

AI-Driven Computer Device for Mobile and Automotive System Monitoring

A system may receive information from a system under test, such as an automotive system under test, and capture multiple display streams from the system under test. The display streams may be processed and composited using virtual serializer / deserializer (virtual SerDes) operations that combine the multiple streams into a single super-frame format. The composited stream is then encoded and broadcast. The system may enable multiple users to simultaneously access and interact with the display streams remotely, with the virtual SerDes operations supporting numerous logical displays for software development and validation. The system may provide synchronized display viewing and allows dynamic switching between multi-display tiled views and single display views while preserving spatial and interleaved super-frame formats.
