Relating to the technical field of batteries, and provided are a battery fault detection method, a battery fault detection system, a terminal, and a computer-readable storage medium. The method comprises: by means of a vibration generation device, sequentially applying a preset number of vibration signals of different frequencies to a battery to be tested (301); collecting response signals of the battery by means of a response collection device (302), the response signals comprising a preset number of vibration response amplitudes of the battery, wherein the preset number of vibration response amplitudes are separately generated by the battery under the action of vibration signals of different frequencies; and according to the response signals, determining whether the battery is faulty (303). By means of the described method, it is possible to quickly and non-destructively detect whether a battery is faulty.

A battery is subjected to ultrasound waves, and resulting re-emitted ultrasound waves are recorded. Based upon how the waves are distorted or reflected, a state of pores within the battery can be evaluated. This evaluation can be used to verify a rating of the battery included in received data regarding the battery.

Proactively identifying and interdicting transport of commodities associated with illicit nuclear materials and nuclear weapons shielded by high Z-number materials, such as lead, can help ensure effective nuclear nonproliferation. In an embodiment, a method for imaging an object on a surface includes exciting a surface with ultrasonic excitation from an ultrasonic transmitter having an ultrasonic transducer in contact with the surface. The method further includes imaging, at a processor, a two-dimensional representation of the object acoustically coupled to the surface based on the ultrasonic reflections received at an ultrasonic receiver via a receiving transducer in contact with the surface. This method can complement existing x-ray screening systems to increase the odds of detecting radiological materials.

A system for monitoring fruit growth including: a vibration exciter that imparts predetermined vibration to a stem or a branch between a fruit and a stalk growing on a plant; a vibration sensor that detects vibration of the stem or the branch caused by the vibration imparted by the vibration exciter; and a detector that detects a weight or weight change of the fruit based on a frequency of the vibration detected by the vibration sensor.

Systems, apparatuses and methods for growing marijuana plants, particularly for regulated purposes, for example medical purposes or in some jurisdictions recreational purposes, have automated subsystems with sensors to provide feedback information about system, apparatus and plant growth parameters to one or more controllers so that the one or more controllers can alter one or more parameters to provide optimal conditions for the growing and harvesting of the marijuana plants. In particular aspects, the systems, apparatuses and methods provide for control of odors produced during the growing of marijuana, root management of the marijuana plants and control over important levels of chemicals provided to the plants, for example enzymes and flavor additives.

Systems and methods of determining a tension of an anchor embedded in a dam are described. A dynamic impulse response of the dam is empirically obtained in such that a portion of the empirical dynamic impulse response is dominated by a dynamic behavior of the anchor. Furthermore, a set of modeled impulse responses that map to a set of tension values for the anchor are obtained. Next, a closest matching modeled impulse response from the set of modeled impulse responses that is a closest match to the portion of the empirical dynamic impulse response that is dominated by the dynamic behavior of the anchor is determined. Finally, a tension value from the set of tension values is selected, which is the closest match to the portion of the dynamic impulse response dominated by the dynamic behavior of the anchor. As such, the tension value of the anchor can be determined.

An additive manufacturing apparatus according to one embodiment includes a manufacturing unit, an elastic wave generation unit, an elastic wave detection unit, and an inspection unit.
