Abstract: An obstruction marking method includes generating a first echo curve using an electronic level gauge (ELG) coupled to a tank from a first reflected signal (echo signal) received when a material in the tank is at a first level. The ELG includes a radar-based obstruction detection algorithm stored in a memory coupled thereto. A processor implementing the obstruction detection algorithm identifies at least a first feature in the first echo curve to provide at least one suspected obstruction along with its position (first feature position). A second echo curve is generated from a second reflected signal when the material is at a second level. A third echo curve is generated from a third reflected signal when the material is at a third level. The suspected obstruction at the first feature position is stored in the memory as a verified obstruction with its first feature position.

Abstract: A system and a method for measuring a signal propagation speed in a liquid contained in a vessel or in a gaseous medium contained in the same vessel above the surface of the liquid are proposed. A transmitter transmits a first signal in a first direction which is at an acute or right angle to a first reflective surface, wherein the first reflective surface reflects the first signal so that it travels in a second direction is received by a first acoustic or electromagnetic receiver. The transmitter transmits a second signal in a predetermined third direction which is at an acute angle to the first direction, where the first or a second reflective surface reflects the second signal so that it travels in a predetermined and angular fourth direction with respect to the first or second reflective surface and is received by the first or a second acoustic or electromagnetic receiver. The speed of sound is then determined under the assumption that both the first and the second signals travel at the same average speed.

Abstract: A method and system for cancelling body movement effect for non-contact vital sign detection is described. The method begins with sending on a first electromagnetic wave transceiver a first electromagnetic signal with a first frequency to a first side of a body, such as a person or animal. Simultaneously using a second electromagnetic wave transceiver a second electromagnetic signal is sent with a second frequency to a second side of a body, wherein the first frequency and the second frequency are different frequencies. A first reflected electromagnetic signal reflected back in response to the first electromagnetic wave on the first transceiver is received and a first baseband complex signal is extracted. Likewise a second reflected electromagnetic signal reflected back in response to the second electromagnetic wave on the second transceiver is received and a second baseband complex signal is extracted. The first baseband complex signal is mathematically combined with the second baseband complex signal to cancel out a Doppler frequency drift therebetween to yield a periodic Doppler phase effect.

Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

Abstract: A radar object detection system includes a first sensor and a controller. The first sensor emits a first radar signal toward a first area about a vehicle, and outputs a first signal indicative of detected targets proximate to the vehicle. The controller receives the first signal from the first sensor, determines when a trailer is connected to the vehicle based on the first signal, defines a shadow-zone that corresponds to a first portion of the first area obstructed by the trailer from being viewed by the first sensor, and ignores detected targets within the shadow-zone that are indicated by the first signal.

Abstract: A method for angle estimation verification, adapted for verifying an estimated angle calculated by an electronic apparatus having an angle estimator and at least three antennas, is provided. The estimated angle is extracted from the angle estimator. An autocorrelation matrix is generated according to a signal vector formed by a plurality of measurements of a received signal received by each of the antennas so as to obtain a plurality of eigenvalues. Among phase difference data generated by a plurality of antenna groups formed by all different combinations of two of the antennas, a plurality of possible estimated angles corresponding to the phase difference data not caused by a coterminal angle effect are calculated. According to the eigenvalues and the possible estimated angles, whether the received signal corresponds to a single target or multiple targets is determined so as to verify the reliability of the estimated angle.
