Switches that turn the power off when the connected device goes into standby, [30] or that turn other outlets on or off when a device is turned on or off are also available. Switches can be activated by sensors. Home automation sensors, switches and controllers can be used to handle more complex sensing and switching. This produces a net saving ...
Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by ...
A modern "useless machine" about to turn itself off. A useless machine or useless box is a device whose only function is to turn itself off. The best-known useless machines are those inspired by Marvin Minsky's design, in which the device's sole function is to switch itself off by operating its own "off" switch.
Degradation in pinch-off voltage. This is a common failure mode for gallium arsenide devices operating at high temperature, and primarily stems from semiconductor-metal interactions and degradation of gate metal structures, with hydrogen being another reason. It can be hindered by a suitable barrier metal between the contacts and gallium arsenide.
Viera Cast is a Smart TV platform by Panasonic that makes it possible to stream multimedia content from the Internet directly into select Viera HDTVs and Blu-ray players.

Some broadcasters that have ceased signing on and signing off in favour of 24-hour broadcasting may perform a sign-off sequence at a certain time in the night (usually between 10:00 p.m. and 1:00 a.m.) as a formality to signify the end of its operating day (in the United States, the broadcast logging day ends at 12:00 midnight local time).
Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.
