Mechanical Televisions in the 1800s and Early 1900sPrior to electric televisions, we had mechanical televisions.
These early televisions started appearing in the early 1800s. They involved mechanically scanning images then transmitting those images onto a screen. Compared to electronic televisions, they were extremely rudimentary.

The cardiopulmonary aid system provides mechanical compression of the chest for patients with cardiac arrest. It is more commonly used in emergency medicine as an alternative to manual CPR because it provides constant compression at constant speeds in difficult transport conditions and reduces the physical strain on the person performing the CPR.

اجاق برقی یک دستگاه گرمایش الکتریکی یکپارچه برای پخت و پز است. اجاق‌های برقی به‌عنوان جایگزینی برای اجاق‌های سوخت جامد رایج شدند که کارکرد و نگهداری آن به نیروی کار بیشتری نیاز داشت. برخلاف اجاق‌های گازی، آنها شعله‌ای روی اجاق‌های برقی تولید نمی‌کنند. در عوض، جریان الکتریکی عنصر گرمایش را فعال می کند.

An electric stove is an integrated electric heating device for cooking. Electric stoves became popular as a replacement for solid fuel stoves, which required more labor to operate and maintain.Unlike gas stoves, they do not produce a flame on electric stoves. Instead, an electric current activates the heating element.
