French to English translations [PRO] Tech/Engineering - Engineering (general) / Elevators/lifts
French term or phrase:badge à longue impulsion
From specifications for a lift/elevator control system.
"Maintenir le bouton palier appuyé est sans conséquence : traitement activation de la fonction maintenant sur front montant pour compatibilité avec clé au palier / **badge à longue impulsion**"
Explanation: I'm pretty sure that's the sense, though I'm not sure if this is really the 'official' term — if indeed there is one!
But this text seems to be saying that the system, because it reacts (as is normal) only to a rising edge, is insensitive to the LENGTH of the pulse that follows — whether that is someone holding a button in too long, or a keycard that is specifically designed to emit long pulses (presumably to create a greater 'window' for activation)

Most modern access-control 'badges' of this keycard type actually have passive RFID devices, and when they come within range of their target, the RFID circuit is powered and triggers a 'pulse', which can be of varying length, either for coding purposes, or more usually, simply to allow a longer 'window' in which the access control circuit can be triggered — to account for varying distances and the way people may "wave" or "swipe" (etc.) the card past the terminal.

It's really very simply: some keycards emit only a short pulse (all that ought to be necessary!), while others emit a longer pulse (possibly for the reasons already mentioned above); this is a point that rarely needs to be discussed, so isn't often mentioned.
As shown there are a lot of questions about the strange term « badge à longue impulsion ». It may be a wrong translation from another language. I would ask the client for its signification.
Below, I summarize all arguments against « longue-pulse keycard» :
- No Ghits for "badge à longue impulsion", hence highly questionnable - Literal translation of questionable term, unproven - Electromagnetic pulses are always short by definition - Only the rising edge activates the lift - The pulse width is irrelevant, and has no effect - A long waiting time prior to the elevator start is undesired by passengers
Ou Par l'intermédiaire d'une oscillation de plasma, l'énergie d'une longue impulsion laser de pompe peut être transférée à une impulsion courte (« seed »). https://hal-polytechnique.archives-ouvertes.fr/tel-01467094/ (i.e. une série d’impulsions).
Please check the number of Ghits for each particle of the term to translate or the 'translation' and consider how much Ghits you should expect for the compound. What to conclude from the effective frequency?
Je me répète : Les longues impulsions n'existent pas. Les impulsions sont toujours courtes. Ce terme est faux. Voir aussi la définition d'impulsion :
En électricité/électronique, une impulsion est une variation brève et rapide d'un état électrique généralement utilisé comme signal. https://fr.m.wikipedia.org/wiki/Impulsion
Same in English: A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value https://en.wikipedia.org/wiki/Pulse_(signal_processing)
Ce fait devrait être connu de tous les collègues ayant au moins une formation secondaire et qui ont suivies le cours de physique attentivement.
Thank you for this piece of information. Your badge has surely a magnetic stripe.
Credit cards have a magnetic stripe conforming to the ISO/IEC 7813. Many modern credit cards have a computer chip embedded in them as a security feature. https://en.wikipedia.org/wiki/Credit_card A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. https://en.wikipedia.org/wiki/Magnetic_stripe_card
Example: You wouldn’t translate "The driver drove an angry car" as this is pure nonsense, but modify the phrase to "The angry driver drove the car" as angry cars doesn’t exist. It’s the same with "badge à longue impulsion". "pulse" refers to the electronic (also to a card chip, if embedded), not to the badge (identity card). Only the circuit and/or the reader exchange electromagnetic signals, treated by the IT system.

mine, to enter my building, is a rather thin magnet, no card, applied flat against a receiver set on the wall next to the door
Well said that man! I have had arguments in the past with people who refused to believe in the existence of a term of which i had 100% certain knowledge, simply because it didn't happen to have made it onyo Google yet. There is a vast body of knowledge out there that, for one reason or another has not yet found its way onto the 'Net.
Yes, this is more comprehensible. The landing key/button will also activate the system on the first moment of contact as the key card on the rising edge.
I think a "palier" is a landing (i.e. a level where the lift stops and its door opens) and a "bouton palier" is the button you press for the lift to go to a particular landing.
I suppose that the "palier" is the same as "front montant", a rising edge (une flanc montée). But what is "bouton palier"? A button activated by the rising edge?
In essence, 'long pulse' key-card — it is saying it doesn't matter how long (or short) the pulse is: the system responds only to the initial rising edge.
Unfortunately, I could not found a link describing a rising edge issued or generated by a key card or the reader. I found some links for readers communicating to an IT system for verification of the key card using rising edge technology, but not related to the key card as such. I therefore propose to circumscribe the term as following:
"Keeping the button pressed has no consequence: The function is now activated on the rising edge in order to harmonize the selection of the landing either by the key switch contact or the rising edge generated by the key card."
In this case the term "generated by the key card" is also valid if the reader issues the pulses as this is prompted by the card.
