Abstract: A vapor dispensation system includes a base having a vaporizing element, a cylindrical vapor tube extending along a longitudinal axis, a mouthpiece connected to the vapor tube opposite the base, a vial body surrounding the vapor tube from the base to the mouthpiece, and a cartridge dimensioned to fit within the vial body. The cartridge has a frangible seal ruptured by the seal penetrating element when the cartridge is enclosed in the vial body between the mouthpiece and base. A method of filling a vapor dispensation system includes disengaging a mouthpiece, removing a spent cartridge, inserting a fluid containing cartridge with a frangible seal of the cartridge oriented toward the vapor dispensation system, rupturing the frangible seal upon full insertion, and engaging the mouthpiece onto the longitudinal end of a vapor dispensation system.

Abstract: Containers suitable for storing pressurized fluids at cryogenic temperatures of ?62° C. (?80° F.) and colder are provided and comprise a self-supporting liner and load-bearing composite overwrap, whereby means are provided for substantially preventing failure of the container during temperature changes.

Abstract: A telephone handset has a flat satellite antenna mounted thereon, the antenna being movable between a first position, in which the antenna is parallel to and contacting a main portion of the handset, and a second position, in which the satellite antenna faces in generally the same direction as a top surface of the main portion. A cover portion is mounted on a side of the main portion opposite to the satellite antenna and movable between an open position and a closed position to provide, with the satellite antenna, a compact three-fold configuration.

Abstract: In cellular telephone handset having an upper casing and a lower casing, liquid crystal display screens with touch sensitive overlays are provided on each casing. In one mode of operation, the screen on the lower casing will display a telephone keypad and the telephone handset will respond to the touching of the keys from the telephone keypad to dial telephone numbers and will display information on the screen on the upper casing. In a second mode of operation, the screen on the upper casing will display function keys and the telephone handset will respond to the touching of the function keys and will display information on the screen on the lower casing.

Abstract: A secure method for transmitting data on an isochronous network in which data is spread in successive frames in a manner known to the sender and receiver but unknown to other nodes on the network. In one embodiment, some or all bits which comprise a byte are transmitted in different channels (i.e. time slots) so that the bits which comprise a byte are spread over several channels in a pattern known to the sender and receiver but not to unauthorized parties on the network. This bit spreading can be performed in real time and without latency or performance problems. In another embodiment, the channel or channels assigned for communication between two nodes on the network change in a sequence known to the sending and receiving nodes but not known to unauthorized parties.

Abstract: A server, and a number of client stations interconnected by a token ring network, specifically an FDDI-II network. The FDDI-II ring is connected in a star-ring topology, with the server and the clients preferably connected to the network through a wiring closet, as is the usual practice for such a topology. The server has separate physical connections to the single FDDI-II ring with each physical connection to the ring providing access to a separate physical domain. This partitions the same ring into different physical domains, so that an increase in the total effective bandwidth of the network is achieved by the server reallocating the same isochronous bandwidth in each of the domains for reuse by the server. An allocation of bandwidth in an isochronous channel in one domain can be reused by the server in another physical domain.

Abstract: A ring network with dual homing connections to the network from one or more nodes via physically separated concentrators.

Abstract: The invention provides a method and apparatus by which the usage of an existing ring network is extended by implementing spatial reuse of the network bandwidth. By spatial reuse we mean that specific portions of the ring network may reuse the same bandwidth. Essentially, the invention is based on the realization that each station rarely needs to communicate with all the other stations that share its ring. Under normal conditions, a station requires the ability to send messages only to a subgroup of the total number of stations. If the ring network is thought of as a circle and if the communicating stations are contiguous, then these stations occupy only an arc on the circle. Outside this arc, the bandwidth assigned to these stations is not in use. Accordingly, the bandwidth can be reassigned to stations which form other, non-overlapping arcs.

Abstract: A multi-media network bus (MMN-Bus) and Controller (MMNC) serve as a distribution medium between a single high-speed network and multiple user network interfaces (UNIs). The MMNC allocates multiple isochronous channels and packet channels for distribution to the users over the MMN-Bus. The MMNC sends information in standard time segments or master cycles. Following transmission of a start signal, a series of control blocks is sent. The first type of control block is used for communication from the MMNC to each UNI. The second type of control block is used for transmissions from each UNI to the MMNC. Both types of control blocks are used for call setup, call acknowledgement, channel allocation, call end and packet data request. Following transmission of both sets of control blocks, a signal is sent to indicate the beginning of a sequence of isochronous transfers. Each UNI tracks the number of signals, identifying those signals which it should either receive or transmit.

Abstract: A method and system for call set-up and channel resource allocation between a plurality of parties in a multi-media conference call that consists of receiving notice that a Sender (the initiator of the conference) wants to commence a video conference. At that point, the number of channels required by the proposed call is determined. Subsequently, each requested participant is identified as available, busy, or no answer. If the receiver is available and sufficient channels are available, the call is set-up and the present members of the conference are notified of what channel each should transmit on and what channel(s) to listen to for the other participants. As each receiver is added, the Sender may conference with the present Receiver. If it is decided at this point, that the receiver will not participate in the conference, the call to that receiver may be terminated, and the procedure continues for other receivers until the full conference is set up. Individuals may leave the conference at any time.
