Abstract: The subject matter of this specification generally relates to modular vehicles including separable pod and base units. In some implementations, a computing system installed in a vehicle base identifies a vehicle pod that is detachably connected to a chassis on the vehicle base. In response to identifying that the vehicle pod is detachably connected to the chassis on the vehicle base, a communications link can be established between the computing system installed in the vehicle base and a computing system installed in the vehicle pod. Based on information obtained through the communications link, the computing system installed in the vehicle base can determine a particular configuration of the vehicle pod that is detachably connected to the chassis. The computing system can then verify that the vehicle base can safely transport the vehicle pod while the vehicle pod is detachably connected.

Abstract: An example method may include receiving, from a client computing device, an indication of a target drop-off spot for an object within a first virtual model of a first region of a delivery destination. A second virtual model of a second region of the delivery destination may be determined based on sensor data received from one or more sensors on a delivery vehicle. A mapping may be determined between physical features represented in the first virtual model and physical features represented in the second virtual model to determine an overlapping region between the first and second virtual models. A position of the target drop-off spot within the second virtual model may be determined based on the overlapping region. Based on the position of the target drop-off spot within the second virtual model, the delivery vehicle may be navigated to the target drop-off spot to drop off the object.

Abstract: A system includes: a light source; a detector configured to spectrally resolve light across an operative wavelength range; a retroreflector module including a reflector and an optical filter integrated with the reflector, the reflector being configured to retroreflect at least some of incident light across the operative wavelength range; an optical filter configured to filter light across the operative wavelength range, the optical filter having an angular-dependent optical characteristic for light across the operative wavelength range; and an electronic processing module in communication with the detector. The system is configured so that during operation the light source directs broadband light towards the retroreflector module, the detector detects filtered retroreflected light from the retroreflection module, and the electronic processing module determines information about an orientation of the retroreflector module with respect to the detector based on the spectral content of the filtered retroreflected light.

Abstract: An electronic display includes an array of pixels each including a light-emitting element, each light-emitting element having a maximum lateral dimension, Pd, in a plane of the display and each light-emitting element being separated from the light-emitting element in each adjacent pixel by a distance, D, wherein D≥5Pd, the light-emitting elements being arranged to emit light to a viewing side of the display. The electronic display also includes a panel supporting the light-emitting elements, wherein portions of the panel between the light-emitting elements are visible from the viewing side of the display, and the panel is switchable between different optical states. The electronic display further includes a controller in communication with the array of pixels and the panel, the controller being programmed to selectively activate the light-emitting elements to produce an image and to change an appearance of the panel by switching the panel between the different optical states.
