Implementations described and claimed herein include bottle cleaning devices and methods. An exemplary bottle cleaning device comprises a drive system. A shaft is releasably connected to the drive system. The shaft rotates in response to operation of the drive system. A brush system is provided on the shaft to rotate in response to operation of the drive system. The brush system includes at least one brush conforming to an inner side-wall of a bottle.

Bottle cleaning device and methods of operation

A system and method is provided for seamlessly switching between different network access technologies without interrupting active network applications or sessions. A Network Access Arbitrator (NAA), which contains a virtual network adapter driver, resides between a Data Link Layer and a Network Layer of the standard OSI-7 Layer Protocol Stack for controlling necessary switching between different network access technologies. Since all network applications are controlled by layers residing on or above the Network Layer, all applications using network services provided by the Network Layer will continue their active network sessions or applications without disruption, as the NAA switches between different network access technologies.

Method and system for switching between two network access technologies without interrupting active network applications

A communications architecture for enabling IP-based mobile communications includes a Local Service Function (LSF) component configured to serve as an IP-based serving area network for a set of x-Access Networks, and a Network Service Function (NSF) component configured to serve as an IP-based home network by managing a MN's subscription and associated profile so that the MN is authorized to use the resources of the LSF. An x-Access Network (xAN) is interconnected to the LSF and NSF for providing heterogeneous Layer 2 access for MNs irrespective of access technology.

An apparatus, system, and method are provided for interworking the public telephone network and the IP network. The public telephone network transports a TCAP message in a first format, and the IP network transports an encapsulated TCAP message in a second format. A first interface communicates with the public telephone network, and exchanges TCAP messages therewith. A second interface communicates with the IP network, and exchanges encapsulated TCAP messages therewith. A processor operably connected to at least one of said first interface and said second interface translates TCAP messages in the first format to/from the encapsulated TCAP message in the second format. The processor is further adapted for forwarding TCAP messages in both formats to the respective network. The first format can be an SS7 protocol format, while the second format can be an IP protocol format as used in the IP network. Various message structures and encapsulation techniques are provided. Network addressing and routing functions are included. An apparatus for exchanging encapsulated TCAP messages with the IP network is provided. A system for interworking a public telephone network and an IP network is provided. The system comprises a first network node, a second network node, and at least one interworking apparatus having a processor adapted for exchanging TCAP messages with the public telephone network and the IP network, as described. Related methods for interworking between the IP network and the public telephone network are provided.

A system and method for route optimization in a wireless Internet Protocol (IP) network. The system and method send, to a home agent, a data packet; transmit, to a mobile node, the data packet using a first address; maintain a list of correspondent nodes associated with the mobile node; send, to the correspondent node, a binding update message; and transmit, directly to the mobile node, subsequent data packets using the first address. The system and method additionally: transmit, to a home agent, a registration request comprising a new address; transmit, to a mobile node, a registration reply in response to the registration request; compare the new address to an old address; if the new address and the old address are not equal, transmit, to the correspondent node, a binding update message; transmit, to the home agent, a binding acknowledgment in response to the binding update message; and transmit, to the mobile node, all subsequent messages via the new address.

Computer program products, related methods, and a protocol for interworking services between a public telephone network, including an Intelligent Network, and an internet protocol network are provided. A public telephone network transports a TCAP message in an SS7 protocol format, and an internet protocol network, or IP network, transports an encapsulated TCAP message in an IP protocol format. A STIPP (Simple TCAP-IP Interworking Protocol) protocol, represented as a computer data signal including a plurality of bits, is used for exchanging TCAP messages between IP network entities. The computer data signal comprises an internet protocol portion, a transport portion, and a STIP (Simple TCAP Interworking Part) portion. The STIP portion includes a STIP header for encapsulating the TCAP message therein for transmission between IP network entities. Various computer data signal embodiments are provided. A computer program product for an interworking gateway exchanging TCAP messages with a public telephone network and encapsulated TCAP messages with an internet protocol network is provided. Further, a computer program product for an IP network entity exchanging encapsulated TCAP messages with an internet protocol network is provided. Message encapsulation, extraction, and decapsulation are provided. Various embodiments and functions are included for each computer program product. A method for exchanging TCAP messages between a public telephone network and an internet protocol network for services interworking is included. Further, a method for exchanging encapsulated TCAP messages with an internet protocol network, such that TCAP messages can ultimately be exchanged with a public telephone network through an internet protocol network is provided.

A guard for an electrical receptacle uses a rotating cover to mask the slots in the receptacle. Catch pins engage the cover and hold it in its closed position. Springs means, or similar, automatically return the cover to the closed position. In the preferred form, the catch pins engage the same slots which provide access to the slots in the receptacle, allowing the pins to be released by partially inserting the electrical plug. The cover can then be rotated by turning the plug to align with the receptacle slots. The catch pins move with a certain amount of independence, requiring that both be released separately to allow the cover to turn. The guard may be implemented using a modified housing on the receptacle or as a retrofit cover usable with an existing receptacle.
