Animated books combine three elements: story, colored illustrations which include text, and "two or more animated illustrations with their movement mechanisms working between a doubled page". [2] In 1938, Julian Wehr 's animations for children's books were patented as "moving illustrations" that move the picture up and down and horizontally at ...
Help! I'm Trapped... is a series of 17 books written by Todd Strasser, published by Scholastic Press. With worldwide sales of over 10 million copies, the plots mainly center around a group of children and a machine that has the power to switch bodies. The first of the series, Help!

A laptop that has an embedded security switch is stolen. The security switch detects a lack of communication from a specific external source for 12 hours, and responds by disconnecting the screen, keyboard and other key components, rendering the laptop useless, with no possibility of recovery, even with a full format.
An example is a light switch. SPST-NO. Form A [4] Single pole, single throw, normally open A simple on-off switch. The two terminals are normally disconnected (open) and are closed when the switch is activated. An example is a pushbutton switch. SPST-NC Form B [4] Single pole, single throw, normally closed A simple on-off switch.
The most widely used electronic switch in digital circuits is the metal–oxide–semiconductor field-effect transistor (MOSFET). [2] The analogue switch uses two MOSFET transistors in a transmission gate arrangement as a switch that works much like a relay, with some advantages and several limitations compared to an electromechanical relay.
Animation of a lever tumbler lock mechanism. A lever tumbler lock is a type of lock that uses a set of levers to prevent the bolt from moving in the lock. [1] In the simplest form of these, lifting the tumbler above a certain height will allow the bolt to slide past.
The most common form of safety mechanism is a switch, button or lever that when set to the "safe" position, prevents the firing of a firearm. [1] Manual safeties are as varied as the designs of firearms themselves, but the two most common mechanisms are a block or latch that prevents the trigger and/or firing mechanism from moving, and a device ...
The lever is jammed between the back of the notch and its pivot point, stopping movement in that direction against any force that the materials used can withstand. The wheel has little resistance moving in the direction desired, other than that required to lift or push the lever over the next notch.
