Abstract: Systems and methods for operating autonomous vehicles are described. An autonomous vehicle may detect strategy modes and/or actions of other vehicles in a local environment. The autonomous vehicle may then select a strategy mode for its operations based on the detected strategy modes and/or actions of other vehicles, and based on an operational goal for the autonomous vehicle. The strategy modes may include an uncoupled strategy mode, a permissive strategy mode, an assistive strategy mode, and a preventative strategy mode. The autonomous vehicle may further select an action for its operations based on the selected strategy mode.

Abstract: An imaging device may be configured to monitor a field of view for various objects or events occurring therein. The imaging device may capture a plurality of images at various focal lengths, identify a region of interest including one or more semantic objects therein, and determine measures of the levels of blur or sharpness within the regions of interest of the images. Based on their respective focal lengths and measures of their respective levels of blur or sharpness, a focal length for capturing subsequent images with sufficient clarity may be predicted. The imaging device may be adjusted to capture images at the predicted focal length, and such images may be captured. Feedback for further adjustments to the imaging device may be identified by determining measures of the levels of blur or sharpness within the subsequently captured images.

Abstract: Diagnostics may be performed on imaging devices such as digital cameras that are provided in large numbers, or mounted in arrays or networks, by providing imaging data captured from such devices to a machine learning system or classifier that has been trained to recognize anomalies based on imaging data. The machine learning system or classifier may be trained using a training set of imaging data previously captured by one or more imaging devices that has been labeled with regard to whether such imaging devices encountered any anomalies when the imaging data was captured, and if so, which anomalies were encountered. Additionally, a perceptual score which represents the quality of a given image or imaging data may be calculated and used to rank or define the image or imaging data in terms of quality, or determine whether the image or imaging data is suitable for its intended purpose.

Abstract: Depth information may be encoded into pixels of visual imaging data according to steganographic techniques. The depth information may be captured simultaneously with the visual imaging data, and one or more representative pixels may be identified within a region or sector of the visual imaging data according to a pixel traversal strategy. The depth information corresponding to the region or sector may be encoded into one or more least significant bits of the representative pixels, and a modified set of imaging data including the visual imaging data with the depth information encoded into the representative pixels may be stored in a data store and used for any relevant purpose.

Abstract: A reflected light identification (RLID) system uses light to communicate stored information across long distances with minimal interference. The RLID system may include a light source that directs an incident light signal to an RLID structure, which then transmits an encoded light signal to a sensor. The RLID system may include a passive RLID structure (i.e., a structure that does not include power source) such as an RLID reflection surface that includes layered reflective films that reflect the incident light signal back in multiple reflections that serially encodes data. The RLID system may also include an active RLID structure (i.e., a structure that includes power source) that uses energy harvesting to extract and accumulate power from an incident light signal, and then uses the harvested energy to transmit a return signal.

Abstract: Disclosed are various embodiments for obtaining environmental data and operational data from autonomous vehicles in a roadway. A vehicle state of the autonomous vehicles can be updated using data that is obtained from nearby vehicles or other vehicles that are on the roadway. The roadway management system can also generate updates to the vehicle state based upon data obtained from sources external to autonomous vehicles.

Abstract: Preferred points or regions in space for performing a task at a location, e.g., the delivery of an item to the location, may be defined based on sensed positions obtained during the prior performance of tasks at the location. The sensed positions may be identified using a GPS sensor or like system. Vectors including coordinates of the sensed position, and uncertainties of such coordinates, may be clustered into groups at the location. Subsequently identified vectors including coordinates and uncertainties may further refine a cluster, or be used to generate a new cluster. A preferred point or region in space may be identified based on such location hypotheses and utilized in the performance of tasks. Some preferred points or regions may be used for routing vehicles to the location, while others may correspond to delivery points for items at the location.

Abstract: Blur metrics may be calculated for each of the image pixels of a digital image of a scene captured using an imaging device. The blur metrics may be indicative of the level of blur expressed in the digital image, and a blur image representative of the blur metrics may be generated. Subsequently, when another digital image is to be captured using the imaging device, pixel sensors corresponding to high blur metrics may be digitized at a high level of priority, or at a high rate, compared to pixel sensors corresponding to low blur metrics, which may be digitized at a low level of priority, or at a low rate. The blur images may be updated based on changes in blur observed in subsequent images, and different pixel sensors may be digitized at higher or lower levels of priority, or at higher or lower rates, based on the changes in blur.

Abstract: Optical networks may store information or data therein by maintaining the information or data in motion. The optical networks may include optical fiber rings configured to receive optical signals comprising the information or data and to circulate the optical signals within the optical fiber rings. The optical signals and the information or data may be transferred out of the optical fiber rings in order to amplify the optical signals (e.g., to overcome losses due to attenuation within the optical fiber rings), to analyze the optical signals according to one or more processing techniques, or to transfer the information or data to another computer device upon request. If continued storage of the information or data is required, an optical signal including the information or data may be transferred back into the optical fiber rings and may continue to circulate therein.

Abstract: Methods and devices for measuring attributes of objects such as containers and container content without opening the containers are disclosed. Measurements of containers are obtained during conveyance via conveyor. For example, a sensor, such as a pressure sensing system, may measure pressure or contact between the container and the conveyor conveying the container. The measurements may be analyzed to determine characteristics of the container such as the weight, weight distribution and/or dimensions of the container. The conveyor may be configured to jostle the container such that an inertial property of the container and/or container content may be measured and analyzed. The measurements obtained may be used to ascertain a problem or characteristic of the container and/or container content without opening the container, such as damage, packing condition, number of units, presence of liquids, and the like. The method and device may be used through a materials handling facility.
