  • Publication number: 20190197030
    Abstract: Methods and systems for processing incoming data in real-time are described herein. The incoming data is processed in real-time to generate data records that may be improved over time, for example, by automatically correcting inaccurate data in the records. In some embodiments, when data is received, a real-time process is initially performed on the received data under a first time constraint to produce first data for a data record. Subsequently, one or more non-real-time processes are then performed on the received data under a second time constraint to produce second data for the data record. The second data may be used to update the data record, for example, to correct any inaccuracy caused by the real-time process of the received data. Preferably, the second time constraint is longer than the first time constraint.

  • Patent number: 9787969
    Abstract: Systems and methods for processing a pair of 2-D images are described. In one example, a stereoscopic set of images is converted into a collection of regions that represent individual 3-D objects in the pair of images. In one embodiment, the system recovers the 3-D point P for each point p that appears in both images. It estimates the 3-D orientation of the floor plane, and the image capture planes and their height from the floor. The system then identifies the collection B of points P that do not represent points on the floor and generates a projection C of B onto a plane parallel to the floor. It blurs the projection C and identifies peaks in the blurred image, then fits symmetric figures to the points in C around the identified peaks. The system projects the 3-D figures associated with the symmetric figures back onto the 2-D images.

  • Patent number: 9755427
    Abstract: A current clamp circuit based on BCD technology includes a current-outputting circuit, an output-current-sensing circuit, and a current clamp circuit. The current-outputting circuit outputs a current to the output-current-sensing circuit. The output-current-sensing circuit senses the output current. When the current actually output by the current-outputting circuit is greater than a clamp current, the current clamp circuit outputs a current clamp feedback control signal to the current-outputting circuit, so as to clamp the output current clamp at a set value.
