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.
The iron blocks act as keepers by bridging between both poles. In the on position, the poles are each in one iron half, which then acts as an extension. The field is effectively passing across an air gap (at the base and top). If this gap is bridged with a piece of iron, it becomes part of the magnetic circuit and will be fixed to the structure.
An off line regulator, off-line regulator, or offline regulator is an electronic voltage regulation or current regulation device that is designed to directly accept electric power obtained from an alternating current utility power source. That is "off the mains voltage line".
The infinite switch itself was described in a 1975 patent of George F. Esker Jr. and Otto J. Cousins of the Harper Wyman Company. This switch would reset itself as the bi-metallic strip cooled, provided a cycle of calibrated opening and closing. It also provided an indicator light that remained on as long as the knob was not in the closed position.
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off ...
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1275 ahead. Let's start with a few hints.
Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.
When the transistors connecting to 0 turn off, this pull-up transistor determines the output to be 1 by default. In standard NMOS, the pull-up is the same kind of transistor as is used for logic switches. As the output voltage approaches a value less than Vdd, it gradually switches itself off.
