Abstract: Integrated circuit assemblies may contain various mold, fill, and/or underfill materials. As these integrated circuit assemblies become ever smaller, it becomes challenging to prevent voids from forming within these materials, which may affect the reliability of the integrated circuit assemblies. Since integrated circuit assemblies are generally formed by electrically attaching integrated circuit dice on electronic substrates, the present description proposes injecting the mold, fill, and/or underfill materials through openings formed in the electronic substrate to fill voids that may form and/or to prevent the formation of the voids altogether.

Abstract: Techniques for verifying a reliability of map data are discussed herein. In some examples, map data can be used by a vehicle, such as an autonomous vehicle, to traverse an environment. Sensor data (e.g., image data, lidar data, etc.) can be received from a sensor associated with a vehicle and may be used to generate an estimated map and confidence values associated with the estimated map. When the sensor data is image data, images data from multiple perspectives or different time instances may be combined to generate the estimated map. The estimated map may be compared to a stored map or to a proposed vehicle trajectory or corridor to determine a reliability of the stored map data.

Abstract: A computer vision processor of a camera generates hyperzooms for persons or vehicles from image frames captured by the camera. The hyperzooms include a first hyperzoom associated with the persons or vehicles. The computer vision processor tracks traffic patterns of the persons or vehicles while obviating network usage by the camera by predicting positions of the persons or vehicles using a Kalman Filter from the first hyperzoom. The persons or vehicles are detected in the second hyperzoom. The positions of the persons or vehicles are updated based on detecting the persons or vehicles in the second hyperzoom. The first hyperzoom is removed from the camera. Tracks of the persons or vehicles are generated based on the updated positions. The second hyperzoom is removed from the camera. Track metadata is generated from the tracks for storing in a key-value database located on a non-transitory computer-readable storage medium of the camera.

Abstract: This disclosure provides methods, devices, and systems for implementing virtual assistants. The present implementations more specifically relate to virtual assistants with adaptive personality traits. In some aspects, a virtual assistant may store long-term notes about a user. The long-term notes may include information derived from a history of past interactions between the virtual assistant and the user. In some implementations, the long-term notes may include one or more personality traits adopted by the virtual assistant based on the past interactions. The personality traits (and other long-term notes) may be incorporated into prompts sent by the virtual assistant to a natural language processor (NLP) so that the learned personality of the virtual assistant is reflected in the responses returned by the NLP.
