Low-intensity ultrasonic waves can remotely and nondestructively excite central nervous system (CNS) neurons. While diverse applications for this effect are already emerging, the biophysical transduction mechanism underlying this excitation remains unclear. Recently, we suggested that ultrasound-induced intramembrane cavitation within the bilayer membrane could underlie the biomechanics of a ra...

Traveling Wave Ultrasonic Motor (TWUM) is a compact, precise, and silent actuator generating high torque at low speed without gears. Moreover, the TWUM has a high holding torque without supply, which makes this motor as an attractive solution for holding position of robotic arms. However, their nonlinear dynamics, and the presence of load-dependent dead zones often limit their use. Those issues...

Mouse ultrasonic vocalizations (USVs) are often used as behavioral readouts of internal states, to measure effects of social and pharmacological manipulations, and for behavioral phenotyping of mouse models for neuropsychiatric and neurodegenerative disorders. However, little is known about the neurobiological mechanisms of rodent USV production. Here we discuss the available data to assess whe...

The contact interface variables are difficult to measure for an ultrasonic motor. When the motor works under different preloads, error between traditional efficiency model and real output is quite large. In order solve these two problems, we propose a novel model. It takes measured preload feedback voltage data as input, which may offer better accuracy on-line ability. Firstly, effect of on dri...

The system fishcake machine available in the market cannot be controlled by its motor speed based on desired speed. In addition, this uses PLC which causes production cost of to increase, use components that have a small voltage such as 5V and indirectly makes difficult component integrate all types one only. So, paper, we will develop program using MAXI Automation Controllino for control can c...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

This paper designs and implements an automatic parking system for car-like robot. The car-like robot uses Arduino micro control unit as the core for system integration and data computation. It controls peripheral hardware of the car body, including DC motor and driver module, servo motor, ultrasonic range sensor, and Bluetooth module. The image processing often fails in an outdoor setting due t...

This paper presents a new design for a linear ultrasonic piezo motor for precision positioning developed by Physik Instrumente (PI). The stator of the ultrasonic motor consists of a rectangular piezoceramic plate. Two sliders, bonded to a spring which presses them against the stator, move along guides integrated in the stator. These motors are characterized by their extremely simple constructio...
