The support member comprises a parallel 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. An electronically sensitive and mechanically responsive ESMR film is disposed on the support member, one side of the ESMR film is mounted by the film contact surface, and the arched areas are parallel ridges and Align and place in between. The film contact surface mechanically separates each arched area of the ESMR film from the adjacent arched area. More particularly, the present invention relates to the use of a piezoelectric film as the emitter of an ultrasonic parametric transducer. For decades, sound reproduction devices have evolved from mechanical needles on tubes or vinyl discs to analog or digital reproduction via laser and many other electronic media forms. Today, advanced computers and software enable complex programming of signal processing and manipulation of synthesized sounds to create a new dimension of listening experience, including applications within movie and home theater systems.

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. We learned how sensory systems gather stimuli and transduce specific stimuli into action potentials. Photoreceptor cells rods and cones in the retina transduce incident light into neuronal impulses. We record action potentials from neurons , and then we transduce the signal and can extract information about intended movement from that. Avoiding common mistakes with verb patterns 2 March 06, March 11, Essential British English. Essential American English. English—Swedish Swedish—English.

This means that the same pressure in water can be achieved with lower stress on the element. Hydrophone sensitivity varies with frequency due to diffraction from the fiber tip. Transducer 意味 for fragmentation of a target in a body and method for monitoring the fragmentation of a target in a body, transducer 意味.

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.

Transducer 意味

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.

Essential American English. A metal filled epoxy resin which can have an appropriate acoustic impedance for the acoustic matching layer can be injected into the space surrounded by the offset pad prior to placing the crystal. It is possible. DEB4 en. By way of example, the transducer elements can be square, rectangular, elliptical, polygonal, concave, convex, etc. The element is sealed into a housing built on top of a rapid prototyping machine, with the concave side of the transducer in contact with the load medium the ultrasonic medium connecting the transducer to the target. For the modeled results, the properties for PZT-4 are used. CAA1 en. By maintaining precise control over each arched area of the film, such as provided by the mechanistic isolation technique of the present invention, the overall film shape can be made very uniform. The composite matching layer can be formulated and characterized to allow large transducer bandwidth and high pressure output. Due to its high density, a small volume of tungsten is required compared to other powders, which means that the combined mixture is of lower viscosity and is more easily vented.

However, the impedance curves were very consistent between the elements. At low frequencies, there is some model deviation from the measurement caused by the radial horizontal mode in the element, which is not taken into account in the 1-D KLM model. The XxYxZ-6 dB pressure beam width for the simulation was 1. USA1 en. The microtapered construction on which the array element ceramic is bonded can be filled with a suitable epoxy tungsten or other composite material that approximates the acoustic impedance of the ceramic. USA en. The delay circuit can be an active or passive delay. The ESMR film is mounted on a It usually takes 6 weeks to 6 months to get a transducer from a commercial company due to long-term manufacturing procedures. Several material types have been tested with such 3D printing machines. In fact, the inventor has generally experienced that attempts to apply conventional acoustic practices to parametric devices generally result in unsatisfactory results.
