摘要： A method and system determines object orientation using a light source to create a shadow line extending from the light source. A camera captures an image including the shadow line on an object surface. An orientation module determines the surface orientation from the shadow line. In some examples a transparency imperfection in a window through which a camera receives light can be detected and a message sent to a user as to the presence of a light-blocking or light-distorting substance or particle. A system can control illumination while imaging an object in space using a light source mounted to a support structure so a camera captures an image of the illuminated object. Direct illumination of the camera by light from the light source can be prevented such as by blocking the light or using a light-transmissive window adjacent the camera to reject light transmitted directly from the light source.

摘要： A management server in communication with one or more object tracking devices is disclosed. The management server may receive location information, configuration information, and orientation information associated with the one or more object tracking devices. Based at least in part on the location information, the management server may receive weather information associated with the locations of the one or more object tracking devices. Based at least in part on the location information, the weather information, the configuration information, and the orientation information, the management server can determine power generated and power consumed by the one or more object tracking devices, which then can be used to determine estimated operation time for the one or more object tracking devices.

摘要： Analyzing electro-optical imagery from a telescope observing one or more satellites includes capturing one or more images of a plurality of stars and the one or more satellites, and sequentially or randomly selecting each one of a plurality of diagonal lines of pixels in the one or more images. The plurality of diagonal lines of pixels represent one of the plurality of stars in the one or more images. Additionally, a moving average filter is applied to the selected one of the plurality of diagonal lines of pixels to find a location of one of the plurality of start on an x- and y-axis coordinate. Furthermore, the location of the one of the plurality of stars is provided in the one or more captured images to be cross referenced with angular coordinates and radiometric quantities in stellar catalogs.

摘要： A solar tracking system comprises multiple solar panel modules forming a grid of solar panel modules, wherein the multiple solar panel modules are movable relative to a solar source independently of each other; and a control system configured to orient each of the multiple solar panel modules to the solar source independently of each other based on a performance model to optimize an energy output from the grid of solar panel modules, wherein the performance model predicts an energy output from the grid of solar panel modules based on a topography of the area containing the grid of solar panel modules and weather conditions local to each of the solar panel modules.

摘要： A monitoring system that is configured to monitor a property is disclosed. The monitoring system includes a sensor that is configured to generate sensor data that reflects an attribute of the property; a solar panel that is configured to generate and output power; and a monitor control unit. The monitor control unit is configured to: monitor the power outputted by the solar panel; determine that the power outputted by the solar panel has deviated from an expected power range; based on determining that the power outputted by the solar panel has deviated from the expected power range, access the sensor data; based on the power outputted by the solar panel and the sensor data, determine a likely cause of the deviation from the expected power range; and determine an action to perform to remediate the likely cause of the deviation from the expected power range.

摘要： Embodiments of the present disclosure disclose a measuring device of zenith angle, which relates to the technical field of angle measurement and is used to measure solar zenith angle. A light receiving member includes solar panels, a support frame with a regular pyramid structure, and a first counterweight member. Light intensity processing circuits are electrically connected to the solar panels and determine a rotation angle of the support frame based on intensity of light received by each solar panel; a direction adjusting member is electrically connected to the light intensity processing circuits to adjust angles of the support frame in both vertical direction and horizontal direction. The embodiments of the present disclosure have a simple structure, and can avoid limitations on placement angles of the device, measure a zenith angle quickly and accurately, reduce measurement costs, and be made into a small-sized device to facilitate outdoor carrying.

摘要： A device has a microphone array that acquires sound data and a camera that acquires image data. A portion of the device may be moveable by one or more actuators. Responsive to the user, the portion of the device is moved toward an estimated direction of the user. The estimated direction is based on sensor data including the sound data and the image data. First variance values for individual sound direction values are calculated. Data derived from the image data or data from other sensors may be used to modify the first variance values and determine second data comprising second variances. The second data may be processed to determine the estimated direction of the user. For example, the second data may be processed by both a forward and a backward Kalman filter, and the output combined to determine an estimated direction toward the user.

摘要： A tracking device broadcasts beacon signals that are separated in time by broadcast intervals. The tracking device determines the broadcast intervals based on a behavior model. The behavior model specifies one or more conditions, such as times of day within a 24-hour day, and associates a usage probability with each condition. A higher usage probability causes the tracking device to broadcast beacon signals at shorter broadcast intervals. A mobile device in communication with the tracking device can reconfigure the behavior model, either by modifying portions of the behavior model or by replacing the behavior model with a different behavior model. This allows the behavior model to adapt to different circumstances, such as different usage patterns during weekdays, weekends, and vacations.
