Described is a spring mechanism. The spring mechanism includes a leaf spring housing with leaf springs radially disposed within the leaf spring housing. The leaf springs being flexible between a rest state and tension state. A winding mechanism is engaged with the leaf springs for causing the leaf springs to flex from the rest state to the tension state. The winding mechanism includes a pushing pin wheel with a plurality of pushing pins protruding therefrom that rest against the leaf springs. The pushing pin wheel is rotatable such that rotation of the pushing pin wheel causes the leaf springs to flex from the rest state to a tension state. Release of the tension (i.e., when the leaf springs return to the rest state from the tension state) causes rotation of the leaf spring housing, which causes rotation of a corresponding release gear set and output drive.

Spring mechanism

A resource allocator (108) receives, from a first communication unit, a request to establish secure communications with at least a second communication unit. A key identifier is retrieved by the resource allocator and transmitted to at least the second communication unit. Based upon the transmitted key identifier, the second communication unit retrieves an identified encryption key and, at least when the identified encryption key is corrupt, transmits a corrupt key indication to the resource allocator. In response, the resource allocator can assign a default key identifier for use in the secure communication. In this manner, missed communications due to encryption key failures are reduced.

Method for identifying corrupt encryption keys within a secure

In a secure trunked communication system that includes a central controller, communication between a distribution panel and a limited number of console interface units may be achieved in the following manner. At power up or upon a reset condition, the distribution panel transmits a status check message to each console interface unit in the system. Console interface units that are active respond by transmitting an acknowledgement. Upon receiving the acknowledgement, the distribution panel transmits the addresses of the active console interface units to the central controller. When the distribution panel receives secure information from the central controller, it interprets the information to identify a target console interface unit and transmits the received secure information to the target console interface unit.

Method for providing communication between a distribution panel and

In a secure trunking communication system, limited secure service is provided during periods of limited service or failsoft operations using the following method. When the limited service or failsoft condition is detected, a limited secure service message or a failsoft service message, respectively, is transmitted to those system components utilizing encryption keys, including console interface units (CIU) (106-107) and communication units (111-113). Upon reception of the limited secure service message, the communication units load at least one limited service key. Simultaneously, the console interface units also load the at least one limited service key. Upon reception of the failsoft service message, the console interface units load at least one failsoft key. Simultaneously, the communication units also load the at least one failsoft key. The communication units and the CIUs use the limited service keys or the failsoft keys until normal operation is restored.

Method for providing limited secure services in secure trunking

A pouring nozzle for a soft drink, milk or liquor bottle, carton, or the like, which has a feature in that when the container is in an upright position, the nozzle automatically closes to seal off the container. The nozzle includes an internal ball which floats on liquid trapped in the nozzle to close and seal the nozzle when the container is upright. However, the ball is forced into a cavity in the nozzle when the container is tilted over to permit liquid to flow freely from the container through the nozzle.
