Abstract: A driving device includes two rotor assemblies, a stator assembly, and a positioning assembly. Each rotor assembly includes a rotation axis and a rotor. The rotor includes a hollow chamber. The two rotor assemblies include a first rotor assembly and a second rotor assembly, a rotation axis of the first rotor assembly is parallel with a rotation axis of the second rotor assembly, a rotor of the first rotor assembly is at least partially embedded in a chamber of a rotor of the second rotor assembly. The stator assembly is surroundingly disposed at an outer side of the two rotor assemblies and drives a rotor. The rotor driven by the stator assembly causes another rotor of one of the first rotor assembly and the second rotor assembly to rotate. The positioning assembly is located outside of the rotors, and limits the rotors to rotate around corresponding fixed rotation axes.

Abstract: Disclosed are techniques for scanning an optical beam in two dimensions (e.g. azimuth and elevation) and for increasing or decreasing a field-of-view (FOV) of the scanned beam. Scanning may be performed by various configurations of prisms, rotatable mirrors, and/or rotatable polygonal mirrors. In some configuration, changes to the FOV of the scanned beam may be performed by prisms positioned with a predetermined angular relationship and may include other optical components, as well. Depending on the predetermined angular relationship, the prisms can expand the FOV along one or more axis and/or may compress the FOV along one or more axis.

Abstract: Hollow motor apparatuses and associated systems and methods for manufacturing the same are disclosed herein. In representative embodiment, a hollow motor apparatus includes a rotor assembly rotatable about a rotation axis, a stator assembly positioned adjacent to the rotor assembly and coaxially with the rotor assembly relative to the rotation axis, and a bearing assembly operably coupled to the rotor assembly. The rotor assembly has an inner portion around an opening configured to receive at least a portion of a payload. The bearing assembly is disposed outside the inner portion of the rotor assembly and is configured to maintain a position of the rotor assembly relative to the stator assembly.

Abstract: The present disclosure provides a distance detection device. The distance detection device includes a light source configured to emit pulse light beams sequentially; and a scanning module including a first optical module, a second optical module, and drivers. The first optical module and the second optical module are sequentially positioned on an optical path of the light beams emitted by the light source, the drivers drive the first optical module and the second optical module to move to sequentially project the light beams emitted by the light source to different directions and form a strip-shaped scanning range after being emitted from the scanning module.
