All About Stepper Motors - Adafruit Industries
cdn-learn.adafruit.comNov 15, 2021 · Simple Unipolar Driver The simplest type of driver can be built with a handful of transistors. These are simply switched on and off in sequence to energize the phases and step the motor. Unipolar drivers are relatively inexpensive to build, but only work with unipolar motors. There is an excellent tutorial on how to build one at the Arduino site.
Standard of Care: Total Hip Replacement
www.brighamandwomens.orgA hip hemiarthroplasty can be either a unipolar or bipolar prosthesis. The most common form of partial hip 1replacement is unipolar . In a unipolar prosthesis the head is fixed to the stem. In a bipolar prosthesis there is an additional polyethylene bearing between the stem and the endoprosthetic 5head component . Hip Resurfacing
Burden of disease: DALYs - World Health Organization
www.who.intthree diseases (unipolar major depression, adult-onset hearing loss and alcohol use disorders) for which direct mortality is low. Unipolar depression makes a large contribution to the burden of disease, being at third place world-wide and eighth place in low-income countries, but at first place in middle- and high-income countries.

SAR ADC Input Types - Analog Devices
www.analog.comA pseudo-differential unipolar ADC digitizes the differential analog input voltage (IN+ – IN–) over a span of 0V to V FS. In this range, a single-ended unipolar input signal, driven on the IN+ pin, is measured with respect to the signal ground reference level, driven on the IN – pin. The IN+ pin is allowed to swing from GND to V
Stepper motor controllers - STMicroelectronics

www.electronicasi.comEl transistor de efecto de campo (FET) es un ejemplo de un transistor unipolar. El FET tiene más similitudes con un transistor bipolar que diferencias. Debido a esto casi todos los tipos de polarización acerca de los transistores bipolares se aplican a los transistores de efecto de campo con ciertas restricciones.
