Abstract: 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.

Abstract: 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.

Abstract: A remote emergency light system provides a base unit that is electrically coupled to one or more remote emergency light fixtures using cables. The base unit may provide power to each of the remote emergency light fixtures using the cables to activate the remote emergency light fixtures during an emergency condition. Alternatively, the base unit may provide a trickle charge to one or more remote emergency light fixtures when each of the remote emergency light fixtures includes an energy charging device. The base unit may be configured to communicate with the remote emergency light fixtures and determine when a trickle charge should be sent to a remote emergency light fixture, when a trickle charge should be stopped for a remote emergency light fixture, and/or when an energy charging device needs to be replaced. The cables can meet the requirements for Class 2 circuits as defined by the National Electric Code.

Abstract: An electrical system can include a power supply that provides primary power, and a light fixture having at least one light source, where the light fixture is coupled to the power supply, where the at least one light source illuminates when the light fixture receives the primary power. The electrical system can further include an energy storage unit having at least one energy storage device that charges using the primary power. The electrical system can also include a controller that determines an initial charging period during which the at least one energy storage device is charged using a constant supply of the primary power, where the controller changes the constant supply of the primary power to a trickle charge of the primary power at the end of the initial charging period to maintain a minimum charge level of the at least one energy storage device.

Abstract: 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.

Abstract: 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.

Abstract: Exit and egress lighting, emergency lighting or emergency light fixture, having internal supercapacitor power sources are recharged after a power outage using a staggered power up process. For example, once an emergency light fixture detects a power-on transition from power being unavailable on a power source to power being available from the power source, the fixture waits a predetermined time to recharge a supercapacitor based on a charge time delay value. The predetermined time may be selected to be unique for one or several emergency light fixtures so as to distribute a combined peak power demand of the fixtures. After the predetermined time has expired, the supercapacitor is electrically coupled to a power source to in order to recharge the supercapacitor.
