20160033085 | COMPRESSED GAS STORAGE UNIT AND FILL METHODS - Embodiments are directed to compressed gas storage units exhibiting one or more safety features. Particular embodiments employ a pressure relief mechanism to rapidly yet safely vent the contents of the tank in the event of a fire. The mechanism may comprise an internally piloted relief valve in communication with temperature-sensitive element(s) present along the tank dimensions. Under high temperature conditions indicative of a fire, the element communicates a signal to open the internally piloted relief valve. In some embodiments the element is configured to communicate a heat signal (e.g., by thermal conduction). In certain embodiments the element is configured to communicate a pressure change signal (e.g., pneumatic, hydraulic). In other embodiments the element may communicate different signal types, such as electric (e.g., thermoelectric) or mechanical (e.g., shear or tension forces). Also disclosed is a module incorporating a plurality of tanks to offer enhanced storage capacity. | 02-04-2016 |

20140140246 | MONITORING OF CALL FORWARDING DESTINATION - Monitoring of the final Call Forwarding destination of a terminal that has activated the call forwarding feature. An application server, in an IMS network, checks if the user of the forwarded-to-terminal has activated the call forwarding feature and the application server sends a notification to the (originating) user, indicating that the user of the forwarded-to-terminal has activated the call forwarding feature. The originating user subscribes to the service of receiving the notification and the originating user receives the notification when the user of the forward- to-terminal has the call forwarding feature activated already or attempts to forward his call's at a later point of time. Feature is known as communication diversion notification (CDIVN). | 05-22-2014 |

20140254584 | NOTIFICATION OF TOO MANY "NO ANSWER" OF FORWARDED TO NUMBER - Method and system for notifying subscribers of calls missed by forwarded to number. The present invention relates to services provided by interne protocol multimedia subsystem and more specifically to a system and method of notifying a subscriber about the performance of selected forwarded number. When an call is forwarded to a forward to identity the application server increments a counter in case the call is not answered by the forward to identity. Once this counter reaches a certain threshold, the subscriber is sent a notification of the number of calls missed by selected forward to identity. | 09-11-2014 |
