A smart refrigerator is a refrigerator that is able to communicate with the internet. [1] This kind of refrigerator is often designed to automatically determine when particular food items need to be replenished.
Food in a refrigerator with its door open. A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.

This is a common method of constructing cabinet doors and these are often referred to as a five piece door. When a panel will be large it is common to divide it into sections. Pieces known as mid rails and mid stiles or muntins are added to the frame between the panel sections.
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.
The interface dimensions for SMA connectors are listed in MIL-STD-348. [5] The SMA connector employs a 1 ⁄ 4 inch diameter, 36-thread-per-inch threaded barrel. The male is equipped with a hex nut measuring 5 ⁄ 16 inch (0.3125 inch / 7.9 mm) across opposite flats, thus taking the same wrench as a #6 SAE hex nut.
By comparison, with an inductor with a straight core, the magnetic field emerging from one end of the core has a long path through air to enter the other end. In addition, because the windings are relatively short and wound in a closed magnetic field, a toroidal transformer will have a lower secondary impedance which will increase efficiency ...
