A paternoster in Prague Paternoster elevator in The Hague, when it was still in operation. A paternoster (/ ˌ p eɪ t ər ˈ n ɒ s t ər /, / ˌ p ɑː-/, or / ˌ p æ-/) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two people) that move slowly in a loop up and down inside a building without stopping.
Passengers inside the elevator will be notified with an alarm and indicator light to exit the elevator when the doors open. Once the elevator arrives at the floor, it will park with its doors open and the car buttons will be disabled to prevent a passenger from taking control of the elevator.

Many regional trains in Germany come with platform gap fillers, such as the Bombardier Talent 2. [1] On subway networks, they have also become more common, as evidenced by the Nuremberg U-Bahn whose 1970s first generation VAG Class DT1 do not have them but whose VAG Class DT3 of the 2000s and 2010s and VAG Class G1 of the 2020s come equipped with automatic gap fillers.
window detector circuit diagram. A window detector circuit, also called window comparator circuit or dual edge limit detector circuits is used to determine whether an unknown input is between two precise reference threshold voltages. [1] It employs two comparators to detect over-voltage or under-voltage. [2]
The edge direction angle is rounded to one of four angles representing vertical, horizontal, and the two diagonals (0°, 45°, 90°, and 135°). An edge direction falling in each color region will be set to a specific angle value, for instance, θ in [0°, 22.5°] or [157.5°, 180°] maps to 0°.
Reed switch diagrams from Walter B. Ellwood's 1941 patent, [4] Electromagnetic switch. It illustrates a single pole, double-throw (SPDT) device. Descriptions from the patent text are as follows: Fig. 1 - device shown in nonoperated position Fig. 2 - device shown in operated position Fig. 3 - cross-section 1 - glass envelope 2 - terminal
A functional specification is a kind of requirement specification, and may show functional block diagrams. [citation needed] A design or product specification describes the features of the solutions for the Requirement Specification, referring to either a designed solution or final produced solution. It is often used to guide fabrication ...
