Higher-Frequency Ultrasonic Welding System Designed for Mini Part Manufacturers have little control over operating frequency, which can only be changed by changing the ultrasonic stack. For many years, the most common system frequency was 20 kilohertz. That’s no longer the case.   At present more customers are using 15-kilohertz systems because they need to weld larger parts. Altras...

What is Point-of-Care Ultrasonography? Point-of-care ultrasound refers to the use of portable ultrasonography at a patient’s bedside for diagnostic (e.g., symptom or sign-based examination) and therapeutic (e.g., image-guidance) purposes. Kendall et al. defined the characteristics of point-of-care (emergency) ultrasound . Characteristics of Point-of-Care Ultrasound  E...
