摘要： The invention is based on speed changes of sound/ultrasound pulses and a fixed detecting depth between a transducer and sampling points to collect information of the detecting depth and/or a velocity of motionless and/or moving objects from the sampling points to construct two-dimension or three-dimension images of the sampling points. By taking advantages of a pulse ultrasound and a continuous ultrasound, a method of coded sound pulses can simultaneously collect the information of the detecting depth and the velocity from the sampling points, which improves imaging quality. Calculating a speed of the moving objects by simultaneously detecting time-of-flight (TOF) and TOF shift at same site from two separated piezoelectric (PZT) elements improves testing results with accuracy, simplification and reproducibility. An aliasing can be rectified based on the TOF and the TOF shift.

摘要： An ultrasound array for acoustic wave transmission comprising at least one capacitive micro-machined ultrasound transducer (CMUT) cell (6), wherein the CMUT cell comprises a substrate (4); a first electrode (7); a cell membrane (5) having a second electrode (7′), which opposes the first electrode and the substrate with a cavity (8) there between, wherein the membrane is arranged to vibrate upon the cell activation; and an acoustic window layer (13), overlaying the cell membrane, and having an inner surface opposing the cell membrane and an outer surface. The acoustic window layer comprises a first layer comprising molecules of antioxidant and a polymeric material (47) with insulating particles (41) embedded therein, wherein the polymeric material consists of hydrogen and carbon atoms and has a density equal or below 0.95 g/cm3 and an acoustic impedance equal or above 1.45 MRayl. This acoustic window layer provides an improved acoustic performance, such as wide bandwidth and low attenuation, in application with the CMUT based array.

摘要： An array of micromachined ultrasonic transducers (MUTs). The array has first and second rows, the MUTs in the first row being equally spaced by a horizontal pitch in a horizontal direction, the MUTs in the second row being equally spaced by the horizontal pitch in the horizontal direction. The MUTs in the second row are shifted along the horizontal direction by a first horizontal distance relative to the MUTs in the first row and shifted along a vertical direction by a first vertical distance relative to the MUTs in the first row. The first horizontal distance is greater than zero and less than the horizontal pitch. The first vertical distance ranges from one tenth of a horizontal width of a MUT to a half of a vertical height of a MUT.

摘要： Techniques are disclosed for systems and methods to provide three dimensional target selection for use when operating mobile structures. A three dimensional target selection system includes a logic device configured to communicate with a user interface and receive volume data from a volume data source. The logic device is configured to render a first perspective of a three dimensional representation of the volume data on a display of the user interface, determine a first viewpoint vector within the 3D representation based, at least in part, on a first user input received by the user interface; and identify an object or position within the volume data based, at least in part, on the first viewpoint vector and the first user input.

摘要： A system for managing material accumulation relative to ground engaging tools of an agricultural implement may include a ground engaging tool and an acoustic sensor configured to generate data indicative of an acoustic parameter of a sound produced as the ground engaging tool engages the ground when a ground engaging operation is performed within a field. Additionally, the system may include a controller communicatively coupled to the acoustic sensor. The controller may be configured to monitor the data received from the acoustic sensor and determine a presence of material accumulation relative to the ground engaging tool based at least in part on the acoustic parameter.

摘要： To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and a high-speed serial data module may be used to move data for all received channels off-chip as digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. Various novel waveform generation techniques, transducer configuration and biasing methodologies, etc., are likewise disclosed. HIFU methods may additionally or alternatively be employed as a component of the “ultrasound-on-a-chip” solution disclosed herein.

摘要： An image processing device according to an aspect of the embodiment includes a display controller and a determining unit. The display controller generates a synthesized image when viewing a perimeter of a vehicle from a virtual viewpoint based on an image from an image capturing device and causes a display unit to display the synthesized image. The determining unit determines, in a case where a screen other than a virtual viewpoint screen including the synthesized image is displayed on the display unit, whether a switching condition to a notification screen for notifying an occupant of presence of an obstacle is satisfied when the obstacle is detected by a detector. The display controller causes the display unit to display the notification screen obtained by superimposing a predetermined notification image on the virtual viewpoint screen, when the determining unit determines that the switching condition is satisfied.
