摘要： In a method and system for inspecting the condition of a structure, the structure is scanned with a three-dimensional (3D) scanner. The 3D scanner includes a sensing system having one of a radar sensing device or an ultrasonic detection device. The sensing system detects 3D information about a subsurface of the structure, and the 3D scanner generates 3D data points based on the information detected by one or more of the radar sensing device and the ultrasonic detection device. A 3D model is constructed from the 3D data and is then analyzed to determine the condition of the subsurface of the structure.

摘要： A ranging function is implemented using a collection of core independent peripherals (CIPs) in a microcontroller without software overhead to the central processor during operation thereof. A pulse width modulation (PWM) peripheral generates a high frequency drive signal, a counter to set the duration of the PWM drive signal (pulse), and a second timer coupled to a comparator to measure the time it takes to receive back a reflection of the ranging signal from an object. The ranging peripheral starts ranging with ultrasonic pulses, and when corresponding reflected ultrasonic pulse are receives an interrupt signal is provided when the ranging measurement is complete. Time dependent sensitivity and/or gain adjustments are contemplated. The ultrasonic ranging peripheral uses on chip resources for most of its functions and therefore requires very few external components. It's set and forget nature may be based on CIP based timers, signal generators and configurable logic cells.

摘要： 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.

摘要： Technologies are generally described for an integrated circuit that is designed to serve as the basis of SONAR sensors that provide high sensitivity, low noise, low cost, and electronically adjustable gain in a small package may incorporate transducer drivers and signal sensing functions. Electronically programmable gain of the circuit may provide flexibility in system designs for gain management, and eliminate a need for manual gain adjustments in production. Power may be supplied to the sensor(s) over a power line of the circuit from a direct current source through a resistor. The same line may also be used for communicating with the sensor(s). Data from the microcontroller may be transmitted to the sensor(s) using an open-drain driver transistor and received through another transistor isolating the micro-controller's input from potentially high voltages present on the power line.

摘要： 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.

摘要翻译： 脉冲波（PW）多普勒具有相同的发射和反射脉冲频率，因为它在接收到先前反射的脉冲之后发射下一个超声波脉冲。 但是，正向血流将与发射的超声脉冲相互作用并缩短其飞行时间（TOF），从而在计算的TOF和检测到的TOF之间产生正的TOF位移。 如果前进速度太快，导致TOF偏移量超过计算出的TOF的一半以上，反射超声波脉冲被认为是来自具有较长TOF的先前发射脉冲，这将显示负的TOF偏移，并被误解为混叠。 无论前进流速如何快速，这种混叠TOF移位可以完全纠正到正确的配准。 因此，TOF移位理论的优点可以更好地量化解释PW多普勒频谱特征，更准确地计算流速。
