Margaret A. Wilcox (1838 – March 30, 1912) was an American mechanical engineer and inventor best recognized for her late-nineteenth-century discoveries. The automotive heating system, her most famous invention, established the foundation for modern vehicle temperature control. She also contributed to the development of home appliance technology.
In 1800, Volta invented the first true battery, storing and releasing a charge through a chemical reaction instead of physically, which came to be known as the voltaic pile. The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth or cardboard soaked in brine (i.e., the electrolyte ).
360 Vis Nav. 2023. The Dyson 360 Vis Nav is a robot vacuum cleaner that was released in May 2023. It has a 360-degree vision system that uses time-of-flight sensors and a camera to map the home and navigate intelligently. It also has a full-width brush bar, a piezo sensor, a HEPA filter, a long-lasting battery, and a smart app.
A heater core is a radiator -like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
A gasoline heater is a small gasoline-fueled space-heater. Fixed versions were originally used mainly for supplemental heat for passenger compartments of automobiles and aircraft, with the latter still in production. Portable versions were also made. Gasoline heaters were commercially available on automobiles starting in the 1930s with ...
Block heater. Electrical cord for powering a block heater. A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block .
An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". Used on many cars in the early 20th century, ignition ...
Some color variation can be observed between types, caused by differences in the gas mixtures used. Longer-life tubes that were manufactured later in the Nixie timeline have mercury added to reduce sputtering resulting in a blue or purple tinge to the emitted light. In some cases, these colors are filtered out by a red or orange filter coating ...
