摘要： Methods, devices, and systems are described for free space optical communication. An example device can comprise a defocuser configured to receive an optical signal from a laser and control a beam divergence of the optical signal. The device can comprise a controller configured to cause the defocuser to adjust the beam divergence based on an operational mode of the laser.

摘要： A system may be configured to provide a main body, configured to house a plugin card, and a card connector, including a first printed circuit board (PCB) having a backplane configured to electrically couple to the plugin card, a third PCB having a plurality of ruggedized connectors configured to couple to an external system, and a second PCB interposed between the first and third PCBs. The processor may be mounted on the second PCB and may determine a state of at least a portion of the system based on a sensor output, an input signal and/or an output signal, and an internal data value. The state may comprise at least one of operational, less than operational, tampered, needing maintenance, needing repair, and not working. And the determination may be performed via one or more criteria being satisfied.

摘要： Methods, systems, and apparatuses, among other things, may detect and store activity in videos based on a spatiotemporal graph representation. Spatiotemporal proximity graphs may be built based on one or more received tracks and may include one or more nodes and each node may include one or more attributes associated with a corresponding entity. One or more spatiotemporal relationships may be identified between the entities based on each spatiotemporal proximity graph one or more activities of the entities may be identified based on the spatiotemporal relationships.

摘要： A system may be configured to predict total electron content (TEC) in an ionosphere. Some embodiments may: provide a machine learning (ML) model; obtain a dataset; input the dataset into the ML model; predict, for a predetermined number of days, the TEC using the ML model; and observe a performance improvement over the obtained dataset based on the prediction, the prediction being made for a region having a number of ground transmitters satisfying a sparseness criterion.

摘要： The present application is directed to a method for enhancing security. The method includes a step of sending a request to a cloud provider to create a server on a cloud. The method also includes a step of receiving a notification from the cloud provider that the requested server is available on the cloud. The method also includes a step of embedding the server with a VPN service. The method further includes a step of sending a credential of the server to an entity on the network. Yet further, the method includes a step of reviewing a list of servers created by the cloud provider. Yet even further, the method includes a step of evaluating progress of server generation by the cloud provider and one or more additional cloud providers. The application is also directed to system for enhancing security on a cloud server.

摘要： Methods, devices, and systems are described for free space optical communication. An example method can comprise generating a first linearly polarized optical signal and converting the first linearly polarized optical signal to a first circularly polarized optical signal. The first circularly polarized optical signal can be output into free space. The method can comprise converting a second circularly polarized optical signal, received via free space, to a second linearly polarized optical signal. The second linearly polarized optical signal can have a linear polarization different than a polarization of the first linearly polarized optical signal. The method can comprise directing, via a polarizing beam splitter, the second linearly polarized optical signal to a first path separate from a second path from which the polarizing beam splitter received the first linearly polarized optical signal.

摘要： A system may be configured to collect geospatial features (in vector form) such that a software application is operable to edit an object represented by at least one vector. Some embodiments may: generate, via a trained machine learning model, a pixel map based on an aerial or satellite image; convert the pixel map into vector form; and store the vectors. This conversion may include a raster phase and a vector phase. A system may be configured to obtain another image, generate another pixel map based on the other image, convert the other pixel map into vector form, and compare the vectors to identify changes between the images. Some implementations may cause identification, based on a similarity with converted vectors, of a more trustworthy set of vectors for subsequent data source conflation.

摘要： A system may be configured to detect an unseen object. Some embodiments may: train a machine learning (ML) model, with training data and with both a positive-support content item and a negative-support content item; and predict, via the trained ML model, presence, within a region, of an object in a newly-obtained content item. The object may (i) not have previously been used to train the ML model and (ii) be among a background and a candidate object present in the newly-obtained content item.
