Microwave signals are transmitted into the container and their fractions reflected back to the fill-level measuring device. These are received as received signals. Echo functions are derived, which show amplitudes of the received signals as a function of a position corresponding to their travel time traveled in the container. A container floor echo is detected at a position, which lies in an earlier determined, both sides limited, empty echo position range, in which the container floor echo occurs in the case of empty container, at an empty echo position dependent on a shape of the container and an installed position of the fill-level measuring device. | 03-14-2013 |

A fill level is measured taking into consideration a phase relationship between the transmitted and received signals related physically with the fill level to be measured. In each measuring cycle, based on the received signal, an auxiliary signal is derived reflecting amplitude and phase information in the received signal as a function of travel time, based on the auxiliary signal, a travel time of a signal fraction reflected on a surface of the substance is determined as fundamental travel time are determined, based on the travel times of the zero crossings of the auxiliary signals determined in the current and in a plurality of preceding measuring cycles, a phase appearance-frequency distribution is derived as a function of travel time, which gives appearance-frequencies, with which zero crossings were present on the respective travel times in the associated auxiliary signals, a travel time of a maximum of the frequency distribution lying nearest the fundamental travel time is determined as fill level travel time, and the fill level is determined based on the fill level travel time. | 12-11-2014 |

20110170744 | VIDEO-BASED VEHICLE DETECTION AND TRACKING USING SPATIO-TEMPORAL MAPS - Systems and methods for detecting and tracking objects, such as motor vehicles, within video data. The systems and method analyze video data, for example, to count objects, determine object speeds, and track the path of objects without relying on the detection and identification of background data within the captured video data. The detection system uses one or more scan lines to generate a spatio-temporal map. A spatio-temporal map is a time progression of a slice of video data representing a history of pixel data corresponding to a scan line. The detection system detects objects in the video data based on intersections of lines within the spatio-temporal map. Once the detection system has detected an object, the detection system may record the detection for counting purposes, display an indication of the object in association with the video data, determine the speed of the object, etc. | 07-14-2011 |
