Abstract: This document describes methods by which a system determines a pickup/drop-off zone (PDZ) to which a vehicle will navigate to perform a ride service request. The system will define a PDZ that is a geometric interval that is within a lane of a road at the requested destination of the ride service request by: (i) accessing map data that includes the geometric interval; (ii) using the vehicle's length and the road's speed limit at the destination to calculate a minimum allowable length for the PDZ; (iii) setting, start point and end point boundaries for the PDZ having an intervening distance that is equal to or greater than the minimum allowable length; and (iv) positioning the PDZ in the lane at or within a threshold distance from the requested destination. The system will then generate a path to guide the vehicle to the PDZ.

Abstract: Self-mixing interferometry (SMI) sensors can be used for generation of content using an input device without requiring a touch-sensitive surface. In some examples, the SMI sensors can be used to detect characteristics of the input device including position, orientation, and/or motion of the input device and/or force applied by the input device (e.g., force applied by a stylus tip). In some examples, some or all of the characteristics of the input device can be used in processing to generate content, including textual character input and three-dimensional objects. In some examples, the generation of content can use information from one or more additional sensors for the input device and/or from additional devices in combination with the characteristics of the input device based on the SMI sensors for generation of content.
