Title: Active invisible liquid crystal display screen
Inventor: SMITH JEREMY J
IPC: G02F1/1335
Filed: 2000-11-07
Abstract: A liquid crystal display is traditionally optimized for viewing at wide angles in normal lighting conditions. This renders the information being viewed open to all within those viewing parameters. By removing the uppermost polarizing film layer that information becomes invisible to the casual observer and visible only to parties equipped with an external polarized viewing filter. This gives added viewing security in sensitive viewing situations (such as handheld computer use and automated teller machine use).

Title: Multiple wireless units using same telephone number
Inventor: DUERK PAUL BRIAN
IPC: H04M1/725
Filed: 2001-02-22
Abstract: A technique allowing more than one wireless unit (e.g., a plurality of mobile phones) to share a single telephone (i.e., directory) number is disclosed. One telephone number is assigned to more than one wireless unit, where each wireless unit has a different electronic serial number. The mobile switching center (MSC) tracks the current location of each wireless unit and stores this information in a location registration database. Each time an active wireless unit moves out of a cell (or sector) and enters a new cell (or sector), it registers with the MSC which updates its location registration database with the current location of the wireless unit. When the MSC receives an incoming call for a telephone number shared by multiple wireless units, the MSC accesses the location registration database and forwards the incoming call to all the wireless units assigned to the shared telephone number. When one of the wireless units answers, the MSC connects the call between the calling party and the wireless unit. At the same time, the MSC transmits a signal to the remaining wireless units assigned to that telephone number indicating that another wireless unit is conducting an active call. One or more remaining wireless units (i.e., other than the one that answered the call) may join the call-in-progress. Each time a new wireless unit joins the call-in-progress, the wireless units already participating in the call are notified by the MSC.  Similarly, when one of the wireless units originates an outgoing call, the MSC connects the caller to the called party and transmits a signal to the remaining wireless units assigned to the shared telephone number indicating that one of the wireless units is conducting an active call. The other wireless units have the option to join the call-in-progress, and any time a new wireless unit joins the call-in-progress, the wireless units already participating in the call are notified.

Abstract: La présente invention concerne un système et un procédé de gestion de réseau destinés à gérer un réseau dans lequel des voies d'acheminement entre des paires de points d'extrémité prennent différents chemins. Le procédé consiste à collecter, à partir du réseau, une information d'état de niveau de dispositif et de performance, et à les transformer en information de chemin et de voie d'acheminement, puis à partir de cette information à calculer des paramètres qui caractérisent l'état de chacune des voies d'acheminement, et enfin à afficher graphiquement les paramètres de chacune des voies d'acheminement. L'utilisateur obtient ainsi une identification visuelle rapide de l'état, individuellement et en relation l'une à l'autre, de toutes les voies d'acheminement dans le réseau. L'invention concerne aussi un procédé d'interface graphique utilisateur de gestion de réseau dans lequel une représentation de trois axes est affichée en 3D. Chaque axe se rapporte à un paramètre respectif de trois paramètres de voie d'acheminement. Pour chaque voie d'acheminement, un point de paramètre représentant les paramètres des voies d'acheminement est affiché sur ces trois axes en fonction du temps. Une direction et un rythme de changement instantanés sont calculés pour chaque paramètre. Chaque point de paramètre est affiché sous la forme d'un cône dont l'axe central pointe dans la direction instantanée du point de paramètre, et dont la longueur est proportionnelle au rythme de changement du point de paramètre correspondant.
