摘要:
A beam steering system for a free-space laser communication system in a satellite includes a laser that emits a laser beam, a liquid lens assembly with at least one liquid lens to change the direction of the laser beam, and an amplifying optic to amplify the change in direction of the laser beam. The beam steering system may be used to steer a laser beam transmitted to another satellite or received from another satellite. In one example, a satellite may include two beam steering systems, disposed at opposing ends of a frame, where each steering system is configured to cover a hemisphere such that together, the steering systems can transmit and/or receive a laser beam over a 4π steradian sphere. The beam steering system may include a transmit feedback system and a reception system to monitor the direction and signal of the transmitted beam and the received beam, respectively.

An apparatus and a method for detecting, classifying and tracking road users on frames of video data are provided. An object detection unit identifies an object in a frame of the video data. A pre-filtering unit determines whether the identifier associated to an object corresponds to another identifier associated to the same object in the same frame of the video data when the identifiers overlap. A tracking unit matches the identified object to a corresponding object in another frame of the video data, such that a path of the sequence of matched objects is tracked throughout the frames of the video data. A scenario unit determines a safety indicator that is a function of the risk indicators indicating interactions between road users.

A data augmentation machine may form all or part of a data augmentation system that is configured to augment data. The data augmentation machine may be configured (e.g., by one or more software modules) to access data (e.g., by crawling one or more public or private networks), extract metadata based on the data (e.g., from the data and its source), create a link to additional data (e.g., based on the extracted metadata), and augment the extracted metadata (e.g., by storing augmented metadata with the extracted metadata). Such augmented metadata may be presented (e.g., within a user interface), published publicly (e.g., on a webpage), published privately (e.g., in a report available only to premium subscribers of a data augmentation service), or any suitable combination thereof.

A logistics system manages the shipments of goods supplied from a plurality of different shippers by a plurality of carriers. It has a variety of modules integrated with each other to perform various functionalities. For example, it may have a purchasing module evaluating proposals by shippers for respective shipments of goods and awarding contracts for the shipments to the plurality of carriers. It may have an optimization module analyzing the proposals and informing the purchasing module if an opportunity exists for at least some of the shipments to be consolidated, in which case at least one contract awarded by the purchasing module is for a consolidated group of the shipments. It may have a contract administration module maintaining information relating to the status of proposals received and contracts awarded by the purchasing module. It may have a scheduling module scheduling shipments according to the awarded contracts. It may also have a shipment management module tracking the status of shipments awarded by the purchasing module and scheduled by said scheduling module. It may further have a financial module authorizing payments according to the status of shipments tracked by the shipment management module are passed between first and second asynchronous clock domains.

A cam for a brake is provided that allows for greater brake shoe travel and thicker brake linings while providing the same or greater mechanical force as compared to conventional cams. One or more lobes of the cam include multiple portions having varying profiles in axial cross-section. The variation in the cam profiles results in a cam in which the outermost ends or tips of the lobes are longer than in conventional cams yet retain the same mechanical strength.

A method and system allows any peer to efficiently distribute content to all other peers in a peer group using existing propagation mechanisms. According to the invention, binary contents are broadcast over existing propagation mechanisms such as propagation pipes using a generic capability that can be used by any application that wants to multicast binary contents. According to the invention, the binary contents are broken up into file blocks that are then sent over existing propagation mechanisms such as propagation pipes. According to the present invention, the receiving peers negotiate among themselves to make up any file blocks they may have missed from the original broadcast. When each peer has all the file blocks associated with a given parent file, they store the content.
