A pallet safety system includes one or more of a pallet bed monitoring system, a pallet height monitoring system, and a pallet interface monitoring system, each of which provide an emitter and a detector. The safety system may be configured to be retrofit to an existing pallet system and is enabled to monitor the presence of unwanted obstructions at various regions proximate to the pallet bed opening, including a plane region above and parallel to the pallet beds, a region proximate to an interface between the pallet system and a material processing system, and a region between an upper and lower pallet.

An acoustic imaging system includes a controller. The controller may be configured to receive a signal from a microphone and reverberation channel data, update latent variables, latent labels, a source amplitude, and a phase estimation based on an optimization of the signal and reverberation channel data to obtain updated latent variables, updated latent labels, an updated source amplitude, and an updated phase estimation, generate, via a conditional generative adversarial network (cGAN) of the updated latent variables and the updated latent labels, an acoustic source map tuned via the updated source amplitude and the updated phase estimation, optimize the acoustic source map, and output the optimized acoustic source map.

A portion of a line from a line laying vessel to a touchdown support point on or near to the seabed is imaged with a 3 dimensional sonar imaging system to produce coordinates of a series of touchdown points using a time sequence of sonar images, and the time series of touchdown points is recorded.

Trajectory estimate for a sub-sonic projectile can be derived from sampling a wake contribution of an acoustic signal detected at a multi-detector array. The wake contribution is sampled, in time, and the samples are processed to determine a bearing estimate for the projectile from which the acoustic wake derives.

Reflected sonar signals arising from one or more possible unknown objects are distinguished according to a first criterion, and possible shapes each having a defined unique associated point are assigned each of the possible unknown objects. Then the three dimensional points are tracked by the sonar system.

The invention concerns a tank (1) of fluid (4) for a motor vehicle (3), comprising a body (5) arranged to receive the fluid (4) and a system (9) for measuring a parameter of the fluid (4) in the tank (1) from an acoustic wave. According to the invention, the acoustic wave (6) is generated by another system (7), the main function of which is not that of emitting an acoustic wave.

Disclosed is a positioning system and a node network. A terminal included in the present invention is characterized by an invisible light sensing unit that detects invisible light signals, that were emitted from one or more signaling nodes with the same intensity, carrying the location data of each signaling node; and a controller that calculates the user's position based on the location data included in one or more invisible light signals and their received signal strength.

An electronic device, a method thereof, a non-transitory computer-readable recording medium, and a chipset are disclosed. The electronic device includes a sensor module including a plurality of sensor arrays for scanning a target object located in a predetermined vicinity of the electronic device; and a control module configured to determine a direction in which the target object is located, based on a first signal that the sensor module outputs with respect to the target object, and scan the target object located in the determined direction, wherein the sensor arrays are spaced apart from each other.

An echo processor (117) for an ultrasound imaging device (102) includes a frame processor (118) that aligns a plurality (N) of sequentially received frames of echoes based on a set of motion displacement fields for the plurality of frames and combines the aligned plurality of sequentially received frames, thereby forming a compounded frame. A method includes obtaining a set of frames of echoes acquired at different times, determining a motion displacement field based on at least two of the frames of the set, motion-compensating all of the frames of the set based on the displacement field and previously determined displacement fields, and generating a compounded frame based on the motion-compensated frames.
