SYSTEM AND METHOD FOR CALIBRATION OF ECHO SOUNDING SYSTEMS AND IMPROVED SEAFLOOR IMAGING USING SUCH SYSTEMS
A system and method are provided for increasing the resolvability of an echo sounding system by acquiring multiple survey lines under one or more different conditions to produce overlapping swaths of seafloor data. The difference conditions may include one or more of acquiring the survey lines along adjacent paths that are offset by less than a swath width, acquiring survey lines at different headings, and acquiring survey lines at different speeds.
Autonomy first route optimization for autonomous vehicles
Embodiments herein can determine an optimal route for an autonomous electric vehicle. The system may score viable routes between the start and end locations of a trip using a numeric or other scale that denotes how viable the route is for autonomy. The score is adjusted using a variety of factors where a learning process leverages both offline and online data. The scored routes are not based simply on the shortest distance between the start and end points but determine the best route based on the driving context for the vehicle and the user.

Trailer safety system and methods of use thereof
The present invention concerns systems, a kit and methods for monitoring coupling of a vehicle and a trailer or a trailer and another trailer. The system includes two sensors associated with a turntable of a towing vehicle, said sensors consisting of: a contact sensor configured to detect when a skid plate of a vehicle to be towed is in contact with the turntable; and a locking sensor configured to detect when the locking mechanism is in a locked configuration. The system further including a controller operatively connected to the two sensors and configured to receive output signals from the contact sensor and the locking sensor and to determine whether safe coupling has been achieved based on the output signals.
Ultrasound diagnostic apparatus and operation method of ultrasound diagnostic apparatus
In an ultrasound diagnostic apparatus and an operation method of the ultrasound diagnostic apparatus of the invention, a control circuit performs polarization processing on a plurality of ultrasound transducers in a non-diagnosis period, during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, in a case where the cumulative driving time of the plurality of ultrasound transducers for performing the ultrasound diagnosis becomes equal to or longer than a specified time. A transmission circuit generates a first transmission signal having a driving voltage for performing ultrasound diagnosis using a pulse generation circuit in the case of performing the ultrasound diagnosis, and generates a second transmission signal having a polarization voltage for performing polarization processing using the same pulse generation circuit as in the case of generating the first transmission signal in the case of performing the polarization processing.
Automatic egress/ingress detection in an acoustic positioning system
A method for finding door location in an automated way based on observations of people that are equipped with a device whose position is determined acoustically. By observing positioning transitions across internal structures such as walls, the location of doors can be automatically identified.

Two dimension and three dimension imaging based on speed changes of sound/ultrasound
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.
