Cabin situation alert system

   
   

Each flight attendant would carry a small portable receiver/transmitter device, similar in size to a pager, and a central receiver/transmitter located in the cockpit. Each portable receiver/transmitter has a numerical designation (1, 2, 3, etc.) which is unique to that one device. The portable receiver/transmitter has two buttons (yellow alert and red alert), a numerical display, indicator lights, and a vibrator. In a developing situation, a nearby flight attendant presses either the yellow or red alert button (depending on the severity of the situation), producing a radio frequency (RF) signal. The central receiver/transmitter receives, processes, and re-broadcasts the signal to all other portable receiver/transmitters worn by flight attendants. The portable receiver/transmitters vibrate to alert the wearers to the situation. A light (either red or yellow) illuminates on all portable receiver/transmitters, and the numerical designation of the sending receiver/transmitter appears on the displays. In addition, a light corresponding to the sending receiver/transmitter's numerical designation appears on the central receiver/transmitter, as well as an audible alarm sound.

Chaque préposé de vol porterait un petit dispositif portatif de receiver/transmitter, semblable dans la taille à un pagineur, et à un receiver/transmitter central situé dans l'habitacle. Chaque receiver/transmitter portatif a une désignation numérique (1, 2, 3, etc...) ce qui est unique à ce un dispositif. Le receiver/transmitter portatif a deux boutons (alerte alerte et rouge jaune), un affichage numérique, les voyants de signalisation, et un vibrateur. Dans une situation se développante, un préposé de vol voisin appuie sur le bouton alerte jaune ou rouge (selon la sévérité de la situation), produisant un signal de la fréquence par radio (rf). Le receiver/transmitter central reçoit, des processus, et re-annonce le signal à tout autre receiver/transmitters portatif porté par des préposés de vol. Les receiver/transmitters portatifs vibrent pour alerter les porteurs à la situation. Une lumière (rouge ou jaune) illumine sur tout le receiver/transmitters portatif, et la désignation numérique du receiver/transmitter d'envoi apparaît sur les affichages. En outre, une lumière correspondant à la désignation numérique d'envoi de receiver/transmitter's apparaît sur le receiver/transmitter central, comme un bruit d'alarme sonore.
