The method further includes decoupling the driving electrode and the ground electrode of the ultrasonic transducer from the power supply and the ground, respectively, to float the driving electrode and the ground electrode of the ultrasonic transducer during a second time period based on the received drive signal to store a charge between the driving electrode to the ground electrode.

The present invention provides a method for storing an ultrasonic scan image and an ultrasonic device. The ultrasonic device may include: an image acquiring unit configured to scan a target object to obtain an image; a buffer unit configured to store the obtained image; a processing unit configured to compute a similarity of a frame of the image; and a storage unit, wherein when it is determined that the computed similarity of the frame is less than a threshold, the processing unit stores frames with a similarity equal to or greater than the threshold previous to the frame in the storage unit. Therefore, the image may be stored automatically based upon the similarity information of the frame of the ultrasonic scanning image.

A flash lamp 32 excites a laser rod 31. A Q switch 35 which changes the loss of the optical resonator according to the voltage applied is inserted on the optical path of a pair of mirrors 33 and 34 forming the optical resonator. An optical path shutter 39 is provided on the optical path of laser emission light. In a first operation mode in which laser emission is performed, the optical path shutter 39 is opened and the voltage applied to the Q switch 35 is changed from a high voltage to, for example, 0 V to emit pulsed laser light after the flash lamp 32 excites the laser rod 31. In a second operation mode in which the laser emission is interrupted and waited for, the optical path shutter 39 is closed and the voltage applied to the Q switch 35 is, for example, 0 V.

A testing apparatus for an optoacoustic device includes a light pulse sensor operatively connected to a light output port of the optoacoustic device, the light pulse sensor being adapted to sense a pulse of light capable of generating an optoacoustic response in a subject and to distinguish between the light pulse and the at least one other light pulse on the basis of the predominant wavelength. The light pulse sensor outputs a trigger signal associated with the distinguished light pulse when such light pulse is sensed. A transducer signal simulator outputs a first plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a first wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a first wavelength. The simulator outputs a second plurality of electrical signals simulating those produced by a transducer array and reflective of an optoacoustic response in a subject to a light pulse at a second predominant wavelength in response to a trigger signal from the light pulse sensor associated with a light pulse having a second wavelength. Conductors carry the plurality of electrical signals output by the transducer signal simulator to the pins of a multi-pin connector.

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.

A method for non-destructive inspection of at least one test object on a workpiece includes the steps of: obtaining a theoretical position of each test object in relation to a testing robot; capturing an image of each test object to obtain image data; determining a real position of each test object in relation to the testing robot on the basis of the image data; and bringing a sensor carried by the testing robot in contact with each test object to obtain a respective test measurement. For the certain type of inspection where the test instrument needs to be brought in physical contact with the test object to be inspected, it is crucial to know the exact position of the test object. As soon as the approximate position of the test object is known an image of the test object can be captured, and the exact position of the test object can be extracted from the respective image data.

A method and apparatus for inspecting an object. The apparatus comprises a vibration generator and an acousto-optical sensor. The vibration generator is positioned relative to a surface of an object. The vibration generator excites the object at a location on the object such that the portion of the object vibrates. The acousto-optical sensor is coupled to the surface of the portion of the object. The acousto-optical sensor detects a vibratory response generated by the portion of the object in response to excitation of the portion of the object and generates an image of the portion of the object based on the vibratory response.
