摘要:
An actuating device (2; 26; 300) and projection and imaging systems (105; 205) using said actuating device are provided. The actuating device includes at least one actuator arm (16; 31, 33, 35, 39; 52, 54, 56, 58; 62, 64, 66; 302, 308) having a piezoelectric membrane. The actuator arm has a width 20 at least ten times its thickness. The actuating device also includes a moveable element (4; 40; 68 304; 70), connected to the actuator arm, such that actuation of the actuator arm causes movement of the moveable element.

An optical microphone arrangement comprises: an array of optical microphones (4) on a substrate (8), each of said optical microphones (4) providing a signal indicative of displacement of a respective membrane (24) as a result of an incoming audible sound; at first processor (12) arranged to receive said signals from said optical microphones (4) and to perform a first processing step on said signals to produce a first output; and a second processor (14) arranged to receive at least one of said signals or said first output; wherein at least said second processor (14) determines presence of at least one element of human speech from said audible sound.
摘要:
A method for detection and imaging of ultrasound contrast agents using multi-pulse transmit schemes, is described. The method is based on transmitting at least two pulses along each radial image line, where the purpose is to introduce a physical movement or a change in ultrasound scattering properties for the contrast agent. The image reconstruction is based on combining the received echoes resulting from at least two transmit pulses for suppression of tissue signal and detection and imaging of contrast agent signal.
