Method and system for measuring vehicle speed based on movement of video camera

Номер: US20120026329A1
Автор: Michael Y. Vorobiev
Принадлежит: Topcon Positioning Systems Inc

A digital video camera is placed on a vehicle. The video camera is attached to the vehicle and is directed to a surface at a certain angle to the surface. The camera angle can change while vehicle is in motion. The camera angle is constantly measured by angular sensor (i.e., inclinometer). Images of the surface are projected onto a video matrix and transformed into a sequence of digital frames that are formed at a pre-set time interval. A speed of the video camera relative to the surface is calculated as a ratio of an off-set between the adjacent frames and the time interval between the frames. Then a known relative speed of the vehicle can be corrected by multiplication of the height of the camera (above the surface) by a coefficient that equals a ratio of the known vehicle speed and the measured camera speed.

Method for calibrating a propagation-time-based localization system

Номер: US20120122484A1
Автор: Alejandro Ramirez, Christian SCHWINGENSCHLÖGL, Maksym Marchenko
Принадлежит: SIEMENS AG

In a method for calibrating a propagation-time-based localization system in a computer-assisted manner, the position of a mobile object in a predetermined environment can be determined by detecting propagation-time-based variables of multiple base stations, wherein the propagation-time-based variable of a base station represents the propagation time of a signal between an object radio unit and the base station. The object is moved and the variables of the base stations are detected in the process at multiple measuring times. The minimum value of the variables of a base station is associated with a predefined minimum distance between the object and base station and the maximum value with a predefined maximum distance. A predefined dependence of the distances between the object and base station is scaled to the association of the minimum and maximum value. The scaled dependence is then used when determining the position of the mobile object.

The invention relates to a method and a radio device for detecting a movement of at least one receiver, wherein the radio signals are sent from at least one stationary transmitter to the at least one receiver and the received signals are evaluated for determining a movement. The radio signals are designed as a specified bit sequence modulated onto a high-frequency carrier and are demodulated by the receiver to form a receiving sequence that is correlated to determine correspondence with the specified bit sequences stored as a reference sequence. Dependent on the correspondence or errors that can be determined by the correlation, quality indicators for the receiving field strength of the received radio signals are determined, wherein the radio signals having the specified bit sequence are sent from the transmitter having at least two different transmission powers in a series. The series is repeated at temporal intervals and the quality indicators of the received sequences of the series are evaluated to determine a movement of the receiver in relation to the transmitter.

A mobile communications device contains at least two microphones. One microphone is located away from the handset receiver and serves to pick up voice of a near end user of the device for transmission to the other party during a call. Another microphone is located near the handset receiver and serves to pick up acoustic output of the handset receiver (a far end signal). A signal processor measures the frequency response of the receiver. The signal processor performs spectral analysis of the receiver frequency response to determine whether or not the device is being held at the ear of the user. On that basis, the device automatically changes its operating mode, e.g., turns on or off a touch sensitive display screen during the call. Other embodiments are also described.

The present invention relates to processing information generated by GNSS receivers received signals such as GPS, GLONASS, etc. GNSS receivers can determine their position in space. The receivers are capable of determining both coordinates and velocity of their spatial movement. When a receiver is used in any machine control systems, velocity vector heading (in other words, velocity vector orientation) should be determined along with velocity vector's absolute value. Angle, determining velocity vector orientation, is calculated based on velocity vector projections which are computed in navigation receivers. The accuracy of velocity vector orientation calculated based on velocity vector projections strongly enough depends on velocity vector's absolute value. To enhance the accuracy, a method of smoothing primary estimates of velocity vector orientation angles using a modified Kalman filter has been proposed. The bandwidth of this filter is varied depending on current estimates of velocity vector's absolute value which were calculated based on the same velocity vector projections.

Methods and Apparatus for Sensing Organic Tissue

In exemplary implementations of this invention, a radio signal is transmitted between a transmitter and a receiver. Either the transmitter, or receiver, or both, have a directional antenna. When organic tissue passes between (or is stationary between) the transmitter and receiver, the tissue causes a reduction of the received signal strength (RSS) of the signal, as compared to a baseline RSS. The larger the amount of tissue, the greater is the reduction of the RSS. By analyzing the degradation of the signal, information about organic tissue between the transmitter and receiver may be determined. For example, the number of persons passing through a physical threshold may be determined. Or the fact that one person is walking faster than, and catching up with, a second person as they pass between the transmitter and receiver may be determined.
