  • Patent number: 12086511
    Abstract: Collision filtering for autonomous vehicle simulations is disclosed herein. A simulation system can be configured to identify a simulated collision involving a simulated autonomous vehicle and a simulated agent representing an obstacle with which the simulated autonomous vehicle may collide. For example, the simulated collision can be simulated based on logged data from a real-world autonomous vehicle. The simulation system can classify the simulated collision as unrealistic or realistic. For example, classification can involve considering a nature of the simulated agent (including, e.g., whether the simulated agent is a drivable obstacle), a nature of the collision, whether the collision is avoidable through an evasive maneuver, whether the collision is similar to a known false positive, and/or input from a human operator.

  • Patent number: 8188955
    Abstract: A source driving circuit adapted to drive a display panel is provided herein. The source driving circuit includes a first output buffer and a second output buffer responsible for enhancing signals with different polarities respectively. As for the first output buffer, the first output buffer includes a first differential input stage, a first output stage and a second output stage. The first output stage includes a first level adjustment circuit and a first self-bias providing circuit. The first level adjustment circuit provides a first level voltage according to input signals received by the first differential input stage, such that the second output stage thereby provides a first charge current and a second charge current to output a first output signal based on the first level voltage. The first self-bias providing circuit provides a first biased voltage associated with one input signal to control the first level adjustment circuit to operate.

  • Patent number: 7880514
    Abstract: An output buffer including a first differential input stage, a primary output stage, and a secondary output stage is provided herein. The first differential input stage respectively receives a first and a second input signals via a first and a second input terminals. The primary output stage includes a first and a second output stages. The first output stage provides at least one first level voltage according to the first and the second input signals, and the second output stage controlled by the first level voltage drives an output terminal of the output buffer to a target level. The secondary output stage includes a comparator and a third output stage. The comparator compares the induced currents in the first differential input stage, and thereby generates a control voltage. The third output stage controlled by the control voltage drives the output terminal of the output buffer to the target level.
