Donald, Glenda, Michael and Christina Hilliard, all from Oxnard, Calif., won a patent for a jacket with a sensor that "transmits a pulse in the direction of travel of a user and receives reflections from any obstacle in the path".
About 15 minutes before sunrise, powerful radar started receiving reflections from over the horizon while the asteroid was still thousands of kilometers above the Pacific Ocean.
With the method, the reservoir boundary was detected and the distance between it and the drilling tool was measured through transmitting directional high-frequency electromagnetic waves and receiving reflection waves, in process of measurement while drilling (MWD) in the horizontal well drilling.
4) "To Listen": to truly open to receive the reflections of our loved one; to receive their apology, their self-reflection, and their intention.
In SA techniques, a minimum of three non-collinear receiving antennas are used to receive partial reflections from the D region.
The microphones placed at the back of a directional source receive mainly reflections, and hence, do not provide a reliable contribution to deduce the location of sound emission.
Two light transmitting antennas (TAs) and two light receiving antennas (RAs), realized by means of grating couplers, are set in the measurement arms to send light out of the chip and receive back reflections, respectively.
To receive the reflection of the emitted wave, the sonar has the receptor.
The following assumptions are introduced in the considered setting: A1: In the measurement model in (3), it is assumed that the targets act as transmitters and each sensor will receive one reflection of the signal emitted from the targets.
When the listener receives room reflections in addition to the direct signal, which is usually the case, the pattern of reflections depends on the directivity of the source [15].
