Abstract: The present disclosure relates to optical systems and methods for their manufacture. An example method includes coupling a first surface of a light-emitter substrate to a reference surface of a carrier substrate. The method also includes registering a mold structure with respect to the reference surface of the carrier substrate. Furthermore, the method includes using the mold structure to form an optical material over at least a portion of the light-emitter substrate. The optical material is shaped according to a shape of the mold structure and includes at least one registration feature. The method also includes coupling an optical lens element to the optical material such that the optical lens element is registered to the at least one registration feature.

Abstract: A vehicle having a communication system is disclosed. The system includes two electrical couplings, coupled by way of a rotary joint having a bearing waveguide. Each electrical coupling includes an interface waveguide configured to couple to external signals. Each electrical coupling also includes a waveguide section configured to propagate electromagnetic signals between the interface waveguide and the bearing waveguide of the rotary joint. Additionally, the rotary joint is configured to allow one electrical coupling to rotate with respect to the other electrical coupling. An axis of rotation of the rotary joint is defined by a center of a portion of the waveguides. Yet further, the rotary joint allows electromagnetic energy to propagate between the waveguides of the electrical couplings.

Abstract: In one example, a device includes a first platform having a first side and a second platform having a second side that overlaps the first side. The device also includes an actuator that rotates the first platform relative to the second platform. The device also includes a plurality of light sources mounted to the first platform in a substantially circular arrangement around the axis of rotation of the first platform. The plurality of light sources emit a plurality of light beams such that respective adjacent light beams intersect at least at a predetermined distance to the first side. The first side remains at least at the predetermined distance to the second side in response to the actuator rotating the first platform. The device also includes a light detector mounted to the second platform and positioned to at least partially overlap at least one of the plurality of light beams.

Abstract: A sensing device includes a stationary portion and a rotating portion. The rotating portion is spaced apart from the stationary portion by a gap and is configured to rotate relative to the stationary portion. The rotating portion includes one or more sensors that generate data. A communication interface in the rotating portion is configured to encode the data with error correction codes to provide encoded data, modulate a radio frequency (RF) signal that includes a plurality of sub-carriers with the encoded data to provide a data-modulated RF signal (e.g., an orthogonal frequency-division multiplexing (OFDM) signal), and transmit the data-modulated RF signal to the stationary portion via a wireless data transformer. The wireless data transformer includes a first conductive structure in the stationary portion and a second conductive structure in the rotating portion. The first and second conductive structures are inductively coupled together across the gap.

Abstract: The present disclosure relates to systems and methods for occlusion detection. One example method involves a light detection and ranging (LIDAR) device scanning at least a portion of an external structure within a field-of-view (FOV) of the LIDAR device. The LIDAR device is physically coupled to the external structure. The scanning comprises transmitting light pulses toward the external structure through an optical window, and receiving reflected light pulses through the optical window. The reflected light pulses comprise reflections of the transmitted light pulses returning back to the LIDAR device from the external structure. The method also involves detecting presence of an occlusion that at least partially occludes the LIDAR device from scanning the FOV based on at least the scan of the at least portion of the external structure.

Abstract: Aspects of the technology employ sensors having high speed rotating mirror assemblies. For instance, the sensors may be Lidar sensors configured to detect people and other objects in an area of interest. A given mirror assembly may have a triangular or other geometric cross-sectional shape. The reflective faces of the mirror assembly may connect along edges or corners. In order to minimize wind drag and torque issues, the corners are rounded, filleted, beveled, chamfered or otherwise truncated. Such truncation may extend the length of the mirror side. The mirror assembly may employ one or more beam stops, light baffles and/or acoustic/aerodynamic baffles. These sensors may be employed with self-driving or manual driven vehicles or other equipment. The sensors may also be used in and around buildings.
