A sensor synchronization system for an autonomous vehicle is described. Upon initializing a master clock on a master processing node for a sensor apparatus of the autonomous vehicle, the system determines whether an external timing signal is available. If the signal is available, the system synchronizes the master clock with the external timing signal. Based on a clock cycle of the master clock, the system propagates timestamp messages to the sensors of the sensor apparatus, receives sensor data, and formats the sensor data based on the timestamp messages.

Formatting sensor data for use in autonomous vehicle communications platform

Image processing systems can include one or more cameras configured to obtain image data, one or more memory devices configured to store a classification model that classifies image features within the image data as including or not including detected objects, and a field programmable gate array (FPGA) device coupled to the one or more cameras. The FPGA device is configured to implement one or more image processing pipelines for image transformation and object detection. The one or more image processing pipelines can generate a multi-scale image pyramid of multiple image samples having different scaling factors, identify and aggregate features within one or more of the multiple image samples having different scaling factors, access the classification model, provide the features as input to the classification model, and receive an output indicative of objects detected within the image data.

FPGA device for image classification

A window shutter for securing windows. The window shutter comprises at least one first shutter and at least one second shutter. The first shutter is coupled to the second shutter via hinges. The first shutter is affixed to a wall and adjacent to a window frame. The second shutter is operable to swing about a pivot axis of the hinges. The second shutter is used to secure windows provided in the window frame.

Embodiments of the present invention include multi-sensory stereo vision sensors suitable for use in robotics, navigation, machine vision, manufacturing, and other applications. In some cases, a sensor includes a stereo camera that produces image data for use in generating disparity maps to determine the positions of objects in the scene and/or the position of the sensor itself. The stereo sensor may include image sensors that are fastened to a unitary frame to prevent undesired drift and a thermal pad that wicks heat away from a processor. The processor may provide an efficient means to directly compute stereo disparity maps onboard the sensor. A sensor can also include a laser rangefinder that provides range data suitable for calibrating the stereo camera and for improving its accuracy in certain environments. In some cases, the laser is coupled to a spindle, which in turn is driven by a geartrain through a slipping clutch.

A sensor synchronization system for an autonomous vehicle is described. Upon initializing a master clock on a master processing node for a sensor apparatus of the autonomous vehicle, the system determines whether an external timing signal is available. If the signal is not available, the system sets the master clock using a local timing signal from a low-power clock on the autonomous vehicle. Based on a clock cycle of the master clock, the system propagates timestamp messages to the sensors of the sensor apparatus, receives sensor data, and formats the sensor data based on the timestamp messages.

A sensor interface for an autonomous vehicle. The sensor interface generates a plurality of sensor pulses that are each offset in phase relative to a local clock signal by a respective amount. The sensor interface receives sensor data from a sensor apparatus and formats the sensor data based at least in part on the plurality of sensor pulses to enable the sensor data to be used for navigating the autonomous vehicle. For example, the sensor interface may add a timestamp to the sensor data indicating a timing of the sensor data in relation to the local clock signal.

A sensor synchronization system for a sensor apparatus. The system synchronizes a local clock signal with an external timing signal. For example, the external timing signal may correspond to a pulse per second (PPS) signal received from a global positioning system (GPS) receiver. The system further generates a plurality of sensor pulses that are each offset in phase relative to the local clock signal by a respective amount. The system then receives sensor data from the sensor apparatus, and determines a timing of the sensor data in relation to the local clock signal based at least in part on the plurality of sensor pulses.
