Abstract: Users of personalized messaging systems can encounter message fatigue, thereby reducing the efficacy of a message on its intended recipient. Message fatigue can result in wasted computational resources and bandwidth as messages transmitted over a network to the user's client device are not acted upon at the client device. For applications involving desired user interactions and responses, personalized messaging can be a tool to achieve user engagement targets. The systems and methods presented herein may address several of the technical challenges with personalized messaging.

Abstract: A LIDAR system includes a laser emitter configured to emit a laser pulse in a sample direction of a sample area of a scene. A sensor element of the LIDAR system is configured to sense a return pulse, which is a reflection from the sample area corresponding to the emitted laser pulse. The LIDAR system may compare a width of the emitted laser pulse to a width of the return pulse in the time-domain. The comparison of the width of the emitted pulse to the width of the return pulse may be used to determine an orientation or surface normal of the sample area relative to the sample direction. Such a comparison leads to a measurement of the change of pulse width, referred to as pulse broadening or pulse stretching, from the emitted pulse to the return pulse.

Abstract: Systems, devices, and method disclosed herein are generally directed to dynamic generation of dialog-based interactive content that emulates human-like behavior during a sequence of bilateral digital text-based exchanges with the user. The dialog-based interactive content can be grown in real-time based upon the user's interactions with another human entity, and can be specified wholly via a serialized representation, disclosed herein as a vDialog Markup Langua ge (vDML).

Abstract: A support assembly for supporting a rotating body may include first and second supports defining first and second longitudinal support axes and configured to support the rotating body, such that the rotating body is rotatable relative to the first and second supports. A rotation axis about which the rotating body rotates may be transverse to the first and second longitudinal support axes. The support assembly may also include a spine coupled to the first and second supports. The support assembly may also include a motor associated with at least one of the first or second supports and configured to supply torque to rotate the rotating body. At least one of the spine, the first support, or the second support may define a recess configured to receive at least one of an electrical conductor or a data signals link associated with operation of the rotating body.

Abstract: A LIDAR system includes one or more LIDAR sensor assemblies, which may be mounted to a vehicle or other object. Each LIDAR sensor assembly includes a laser light source to emit laser light, and a light sensor to produce a light signal in response to sensing reflected light corresponding to reflection of the laser light emitted by the laser light source from a reference surface that is fixed in relation to the LIDAR sensor assembly. A controller of the LIDAR sensor assembly may calibrate the LIDAR sensor assembly based at least in part on a signal from the light sensor indicating detection of reflected light corresponding to reflection of a pulse of laser light reflected from the reference surface.

Abstract: Techniques are described for aligning optical components within a LIDAR assembly. The techniques may be performed to align the optical components during manufacturing or assembly of the LIDAR assembly. For example, a first optical element (e.g., one of a light source or light sensor) may be installed in the LIDAR assembly. An optimal alignment for a second optical element (e.g., the other of the light source or light sensor) may be determined and the second optical element may be installed at the optimal alignment. The optimal alignment for the second optical element may be determined based on detected signals, for example, which may correspond to an alignment resulting in a strongest return signal, highest quality return signal, and/or minimal interference. Additionally or alternatively, techniques may be used to align optical components at runtime by using an actuator to move one or more components of the LIDAR assembly during operation.

Abstract: Systems and methods for dynamic generation of a user interface for display on a display device of a user are described herein. A first set of payload elements associated with a user interface element to be rendered on the user interface can be identified. The first set of payload elements can be filtered by comparing keywords of each payload element to a user interface keyword to generate a second set of payload elements. The second set of payload elements can be filtered by comparing logic of each payload element to user parameters. A final payload element can be selected based on weighted random selection. The user interface can be rendered on the display with the final payload element as the user interface element.

Abstract: A LIDAR system emits laser pulses, wherein each pulse is associated with a power level. A laser emitter is adjusted during operation of a LIDAR system using power profile data associated with the laser. The power profile data is obtained during a calibration procedure and includes information that associates charge duration for a laser power supply with the actual power output by laser. The power profiles can be used during operation of the LIDAR system. A laser pulse can be emitted, the reflected light from the pulse received and analyzed, and the power of the next pulse can be adjusted based on a lookup within the power profile for the laser. For instance, if the power returned from a pulse is too high (e.g., above some specified threshold), the power of the next pulse is reduced to a specific value based on the power profile.

Abstract: An open compiler system for the construction of safe and correct computational systems. This system allows a user to define multiple computational resources, each of which containing multiple computations, which, together, provide some desired functionality. This system generates the artifacts required to create such computational resources, may verify logical properties of such a system, may integrate user-defined programs in the process of compiling such artifacts, and may allow for the deployment, debugging, and monitoring of such computational resources.

Abstract: A LIDAR system emits laser bursts, wherein each burst has at least a pair of pulses. The pulses of each pair are spaced by a time interval having a variable duration to reduce effects of cross-talk. For example, certain embodiments may have multiple emitter/sensor channels that are used sequentially, and each channel may use a different duration for inter-pulse spacing to reduce the effects of cross-talk between channels. The durations may also be varied over time. The emitters and sensors are physically arranged in a two-dimensional array to achieve a relatively fine vertical pitch. The array has staggered rows that are packed using a hexagonal packing arrangement. The channels are used in a sequential order that is selected to maximize spacing between consecutively used channels, further reducing possibilities for inter-channel cross-talk.
