Inventor: SOLIMAN SAMIR S
IPC: H04B7/26
Filed: 1999-11-30
Abstract: La présente invention concerne un procédé et un appareil permettant l'ajustement dynamique d'une boucle de réglage de puissance ayant pour fonction de maintenir, soit la puissance d'émission d'un signal envoyé par une station de base à une station mobile, soit le rapport signal-bruit d'un signal envoyé par la station mobile (300) à la station de base (400) au-dessus d'un seuil minimal et en-dessous d'un seuil maximal. Les données de position représentatives de la distance et de la morphologie entre la station mobile (300) et la station de base (400) et la vitesse de la station mobile (300) sont déterminées. Les seuils minimal et maximal de la boucle de réglage de puissance sont alors ajustés en fonction des données de position et de mobilité de manière que les seuils minimal et maximal varient à mesure que la distance et la morphologie entre la station mobile (300) et la station de base (400) et la vitesse de la station mobile (300) varient. De plus, la mesure utilisée pour augmenter ou réduire la puissance du signal d'émission est ajustée en fonction de la vitesse de la station mobile (300). Un émetteur envoie le signal à un niveau de puissance commandé par la boucle de réglage de puissance en fonction du seuil minimal ajusté.

Title: Cassette a usage limite
Inventor: SOLOMON MERRILL
IPC: G11B23/28
Filed: 1999-07-08
Abstract: L'invention concerne une cassette à usage limité contenant un bras suiveur fixé pivotant au boîtier au niveau d'une extrémité de sorte qu'il est contigu à la bande enroulée d'une bobine au niveau de son extrémité distale. Le bras suiveur ou un autre bras interdépendant constitue un mécanisme de limitation d'usage permettant de commander le rebobinage et/ou la lecture de la cassette en fonction de la position du bras suiveur et/ou de l'historique des positions. Dans un mode de réalisation, un second bras rotatif disposé en interférence contrôlée par rapport au bras suiveur entraîne le "verrouillage" de ce dernier après un nombre prédéterminé de cycles de lecture/rebobinage sans entraves. Dans d'autres modes de réalisation, le dispositif selon l'invention fait intervenir les dents de freinage existantes d'une bobine de cassette afin d'empêcher le rebobinage de la cassette après qu'une quantité prédéterminée de la vidéo a été visionnée. Dans d'autres arrangements, une position décentrée du bras suiveur utilisée conjointement avec un bras d'arrêt permet de bloquer la bande de façon à empêcher un rebobinage complet uniquement après que la vidéo a été complètement visionnée une fois. Dans d'autres modes de réalisation, une paire de bras est fixée pivotante sur le boîtier au niveau d'une extrémité, de sorte qu'au moins l'un de ces bras soit contigu à la bande enroulée de la bobine réceptrice au niveau d'une extrémité distale. Un des bras suiveurs entrave l'autre pendant une première période de lecture. Les second bras est ensuite libéré afin de suivre la bande réceptrice enroulée et/ou le second bras comprend un mécanisme de limitation d'usage qui est libéré afin de contrôler le rebobinage de la bande en fonction de la position de l'un des bras. L'invention concerne également d'autre modes de réalisation exemplaires.
