A method includes receiving an ultrasound signal at an ultrasound receiver from an ultrasound transmitter. The method also includes detecting movement of at least one object based on the received ultrasound signal and at least one previously received ultrasound signal. The method further includes ...

the new Echo Show needs room to do its spinning dance. You can limit the range of motion it has depending on where you place it, and if the Show hits an obstacle while moving, it will ask if you want it to remember that obstacle is there and limit its movement accordingly. But if ...
or a combination of the two [6]. It is useful to classify the mechanism of valve insufficiency into one of three subtypes: Type I AR is characterised bynormalcusp motion within the context of aortic dilatation or cusp perforation; Type II describesexcessivemotion such as cusp prolapse...

Depending on the dimensions of the void and the wavelength of the radar used for detection, it is not unusual to find ringing (echo effects) from a subsurface air gap which can often be a clue to the presence of the void. Fig. 4.2 shows an example of two possible voids below the floo...
Amazon also announced the new Stick Up Cam. It works indoors and outdoors and can run off its battery, plugged into a wall, or from a solar powered accessory. It’s got everything that the original Stick Up Cam has —1080p HD video, motion detection, night vision — all for 30...
For this example, BC(b)=0.583 and BChom(b,bNN)=0.667, which shows how the measure BChom enhances the echo chamber detection by encoding it into the bimodality of the rotated distribution. A consensus scenario (C) has unimodal distributions in both axes, which should not be significantly ...
with lower cutoff frequencies requiring larger filters. The 30 kHz filter we designed was small enough to fit in the available space while still providing enough noise attenuation at the 200 kHz working frequency of the echosounder. We could not fully characterize the impedance of the load,...
On the test dataset, the model identified abnormal wall motion in individual wall segments with an AUC ranging from 0.837 to 0.901, sensitivity from 79.1 to 85.9%, and specificity from 72 to 81%. Among patients without RWMAs at the time of the index ECG, those classified as positive by ...
