  • Publication number: 20230117848
    Abstract: A method, system, and device for mobile robot operations. The method comprises a mobile robot comprising at least one sensor configured to capture data related to the robot's surroundings traveling on a pedestrian pathway. The method also comprises the mobile robot using the sensor to collect data relating to moving objects in the robot's surroundings. The method further comprises detecting at least one pedestrian within the collected data, said pedestrian moving with a motion pattern. The method also comprises analyzing the pedestrian's motion pattern to determine and output the pedestrian's intent. The system comprises at least one mobile robot configured to travel on pedestrian pathways. The robot comprises at least one sensor configured to capture data related to the robot's surroundings and to collect data relating to moving objects in said surroundings. The system also comprises at least one pedestrian detector.

  • Patent number: 9955047
    Abstract: Method and device for acquiring stream of the precisely time-stamped images, including the modulated light source, controlled by the absolute global real-time-base (e.g. provided by global navigation satellite system (GNSS) controller) and the image acquisition and processing unit, decoding the light modulation waveform and determining the time-stamp for every image frame. The GNSS time and position messages can be used to provide the full time- and location stamps for each frame. Multi-element light sources can be used to have more informative light modulation in the time domain. For time-stamping of several image streams (e.g. from several cameras) multiple light sources with the same modulation can be used.

  • Patent number: 8854030
    Abstract: A method is provided for measuring a frequency response of an object, the method involving: generating an excitation signal having relatively fast changing frequency, defined by a time-domain function; generating at least one reference signal, having a waveform corresponding to the excitation signal; introducing the excitation signal into the object, receiving a response signal from the object; analyzing said response signal in a signal analyzer by correlating the response signal with at least one reference signal during a relatively short sliding time-domain window.

  • Publication number: 20140189491
    Abstract: According to the invented method, web pages are rendered on virtual PC's using different combinations of operating systems and browsers. Rendered web pages are stored as digital color images. For each picture a specific set of features are calculated and compared against the feature of a baseline image. Regions containing differences are marked and stored. Detected differences are displayed as transparent windows on top of browser under test. Transparent windows are sections of baseline browser images. These sections comprise regions where feature error threshold has been exceeded.
