Transducer 意味

The support member comprises a transducer 意味 array of ridges extending along the x-axis and spaced apart by a predetermined separation along the y-axis. The ridge has a front film contact surface for supporting the emitter film in the desired film shape for the purpose of radiating parametric output.

In some embodiments, the custom transducer housing is manufactured using rapid prototyping methods to place multiple single-element, substantially flat transducers so as to share a common focus. Rapid prototyping methods can include, for example, hot melt lamination, 3D printing, and stereolithography. In some embodiments, the treatment system can include a plurality of transducer modules that can be inserted into the openings of the transducer housing. Each transducer module can include an acoustic lens, a substantially flat single element transducer, and a matching layer disposed between the lens and the transducer. Also described are methods of use and manufacture. Claimed benefit, the application of which is incorporated by reference as if set forth herein. The government has certain rights in the invention.

Word forms: regular plural transducers noun Electrical engineering : Computing and control A transducer is an electronic device that converts energy from one form to another, just as a microphone converts sound to electrical energy. The input device, with a transducer in it, senses the quantity under measurement and changes it to a proportional electrical signal. A transducer is a device that converts physical energy into an electrical voltage or current signal for transmission. A transducer is an electronic device that converts energy from one form to another, just as a microphone converts sound to electrical energy. Examples of 'transducer' in a sentence transducer.

Forget doing it or forget to do it? Avoiding common mistakes with verb patterns 2. Add to word list Add to word list. Lentivirus can effectively transduce both dividing and non-dividing mammalian cells. The same viral solution was used to transduce myoblasts in vitro prior to the ex vivo gene transfer to the same animal. The fact that we can transduce the cells with pseudotyped lentivirus indicates the potential for genetic modification of the cells in a therapeutic context. This approach avoids the need to transduce glioma cells from individual patients as it allows gene-based immunotherapy to be given immediately.

In one embodiment , the electroacoustic transducers are oriented so that the electroacoustic transducers emit the surround channel nearly upward. The input transducers , have the same polarity and the output transducers , have opposite polarities. This algorithm , which is the first stage of the algorithm for the minimization of transducers that we present , is independent of the notion of sequential transducers. An ultrasonic probe 11 has transmitting ultrasonic transducers UTt 27a and receiving ultrasonic transducers UTr 27b. Under one embodiment , Finite State Transducers are first combined based on a common core in the Finite State Transducers. Under one embodiment , the finite state transducers are first combined based on a common core in the finite state transducers.

This turnaround makes it difficult to iterate the design and make small changes in order to optimize the transducer. This is important in histotripsy, where short duration pulses cycles are required, preventing the media from heating and maximizing cavitation activity. The ultrasound treatment system of claim 1, wherein each of the plurality of transducers is disposed in a separate transducer module, and the rapid prototyping transducer housing comprises the transducer module. In contrast, low power devices such as electrostatic and other diaphragm type transducers are virtually unacceptable for high power requirements. The support members hold a parallel array of ridges extending along the x-axis and are spaced apart along the y-axis at a predetermined separation distance. In contrast to the well-accepted acoustic principle, the inventors have found that the opposite design criteria are preferred for parametric applications. Rapid prototyping methods can be used to design and build arbitrary geometric shapes, such as existing subtractive eg, machining or shaping eg, injection molding methods. This allows the transmission of most of the sound energy from the transducer to the load, and the construction of a high precision focusing acoustic lens. One transducer was connected to a function generator driven by a 1 MHz short burst. The application of these solder connections is generally not possible to be automated and requires skilled specialists for the assembly process, and over time, mechanical failure can occur during transducer operation.

Amaze your friends with your new-found knowledge! In contrast, low power devices such as electrostatic and other diaphragm type transducers are virtually unacceptable for high power requirements. Right Focus pressure estimated by adding all 8 recorded waveforms without phase error correction red and with phase error correction black. For example, the shape of the convex arched area shown in FIG. Moreover, other machine types especially those that use photopolymers , among others, require unique formulations that are incompatible with the properties of any conventional material, but encompass the same range as plastics. Note that the front surface of more microtapered constructs can be programmed into the fabrication process. Although this device was initially successful in generating cavitation in vivo, the required drive voltage was close to the mechanical failure limit for ceramics as determined above. Rapid prototyping has been accepted in engineering practice as an alternative to machining, as a way to evaluate functional and non-functional components in research. A miniature element endoscopic histotripsy transducer with electronically steerable focus. Instead, Desirets is as if the desired impedance should be realized at the center tap of the piezoelectric transmission line in the KLM model, and thus in addition to the actual matching layer, the first half of the element Forms an ideal matching layer as if it should be treated as a second matching layer.
