| 164 | TIME OF FLIGHT RANGE FINDING WITH AN ADAPTIVE TRANSMIT PULSE AND ADAPTIVE RECEIVER PROCESSING | US14710360 | 2015-05-12 | US20150323667A1 | 2015-11-12 | Richard Przybyla; Andre Guedes; Stefon Shelton; Meng-Hsiung Kiang; David Horsley |
| A rangefinding apparatus and method are disclosed. The apparatus may include at least one processor and memory operably connected to the at least one processor.

The target-tracking process may include steering an optimized ultrasonic pulse toward the target, listening for an echo corresponding to the optimized ultrasonic pulse, and calculating, based on the echo, an updated location for the target. | ||||||
| 165 | CALCULATION OF DETECTING DEPTH AND MOVING SPEED OF OBJECTS WITH CODED PULSES BASED ON SPEED CHANGES OF ULTRASOUND/SOUND | US14645475 | 2015-03-12 | US20150185318A1 | 2015-07-02 | Hai Huang; Tony Huang |
| During transmission, a speed of ultrasound pulses gradually reduces due to their energy loss from acoustic impedance. A thickness and a density of piezoelectric (PZT) elements and a sound speed in the PZT elements decides energy of the ultrasound pulses and their detecting depth. A speed of moving objects and an angle of the moving objects with the ultrasound pulses may change a speed of reflected ultrasound pulses and affect their time of flight (TOF) and TOF shift. A method of Coding ultrasound pulses combines advantages of a continuous wave ultrasound and a pulsed wave ultrasound. So, it can be used to obtained the TOF and the TOF shift and calculate the depth and the moving speed of the detecting objects, which also avoids a problem of an aliasing for highly moving speed of the objects. | ||||||

| 169 | Correcting Aliasing of Pulsed Wave Doppler of Diagnostic Ultrasound | US13341928 | 2011-12-31 | US20130016583A1 | 2013-01-17 | Hai Huang |
| Pulsed wave (PW) Doppler has the same emitted and reflected pulse frequency because it emits the next ultrasound pulse after receiving the previously reflected one. But, the forward blood flow will interact with the emitted ultrasound pulse and shorten its time of flight (TOF), which creates a positive TOF shift between the calculated TOF and detected TOF. If the velocity of forward flow is too fast and causes the TOF shift more than half of the calculated TOF, the reflected ultrasound pulses are considered as from the previously emitted pulses with longer TOF, which will show negative TOF shift and be misinterpreted as aliasing. This aliasing TOF shift can be completely rectified to its correct registration no matter how fast the forward flow velocity will be. So, the advantages of TOF shift theory can better quantitatively explain the spectral characteristics of PW Doppler, and more accurately calculate the flow velocity. | ||||||

| 173 | Method for operating an ultrasonic sensor, and corresponding ultrasonic sensor | US12315660 | 2008-12-05 | US08059488B2 | 2011-11-15 | Martin Reiche |
| In a method for operating an ultrasonic sensor in duplex mode, a transmission trigger for triggering an acoustic transmitted signal is transmitted from a control device for controlling the ultrasonic sensor to the ultrasonic sensor via a first duplex channel at a multiple of a resonance frequency of an ultrasonic converter in the ultrasonic sensor. The transmission trigger is subsequently divided down to the resonance frequency of the converter in the ultrasonic sensor. At least one acoustic received signal which corresponds to the acoustic transmitted signal and which is delayed with respect to the reflection at an object due to the acoustic propagation time is converted by the ultrasonic sensor, using the converter, to an electrical received signal which is transmitted from the ultrasonic sensor to the control via a second duplex channel at the resonance frequency of the ultrasonic converter in the ultrasonic sensor. | ||||||
