  • Publication number: 20200259307
    Abstract: An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.

  • Publication number: 20200257291
    Abstract: An automotive vehicle includes an actuator configured to control vehicle steering, a sensor configured to detect a yaw rate of the vehicle, and a controller. The controller is configured to estimate a yaw rate and lateral velocity of the vehicle via a vehicle dynamics model based on a measured longitudinal velocity of the vehicle, calculated road wheel angles of the vehicle, and estimated tire slip angles of the vehicle. The controller is configured to receive a measured yaw rate from the sensor, and to calculate a difference between the measured yaw rate and the estimated yaw rate. The controller is configured to apply a model correction to the vehicle dynamics model using a PID controller based on the difference, and to estimate a vehicle position based on the estimated lateral velocity and the measured longitudinal velocity. The controller is configured to automatically control the actuator based on the vehicle position.

  • Publication number: 20200250523
    Abstract: In some examples, given an AI model in floating point, a system may use one or more artificial intelligence (AI) chips to train a global gain vector for use to convert the AI model in floating point to an AI model in fixed point for uploading to a physical AI chip. The system may determine initial gain vectors, and in each of multiple iterations, obtain the performance values of the AI chips based on the gain vectors and update the gam vectors for the next iteration. The gain vectors are updated based on a velocity of gain. The performance value may be based on feature maps of an AI model before and after the converting. The performance value may also be based on interference over a test dataset. Upon completion of the iterations, the system determines the global gain vector that resulted in the best performance value during the iterations.
