Abstract:
A multiple application switching platform includes a switch having a distributed open architecture and incorporating redundancy for enhanced fault tolerance. The switch includes at least one shelf having a midplane ( ) containing message buses and TDM data buses (A and B). Shelves may be interconnected to form a group wherein various circuit cards are connected to each shelf midplane. The circuit cards ( and ) perform call processing wherein each card within a group accessing a data bus is pre-assigned a unique set of time slots for each data bus within which that card may transmit onto that data bus. Each circuit card further includes an identification number that enables each card an opportunity to transmit onto a message bus (A and B). The circuit cards ( and ) include line or trunk switch cards that function as an independent switch to interface line or trunks to a shelf midplane. Communications between lines or trunks connected to any group shelf is facilitated by switch cards communicating with each other via messages sent over the message buses (A and B).
Aircraft Data And Voice Communications System And Method
Jon Gilbert - LaJolla CA, US Scott Boden - LaJolla CA, US Roger Atkinson - El Cajon CA, US
International Classification:
H04Q007/20
US Classification:
455/427000, 455/428000, 455/430000
Abstract:
Satellite and terrestrial voice and data communications are included within a communications server system, preferably for an aircraft. The system collects and logs data concerning the aircraft and flight via various sensors. The data may be delivered to a ground facility in real time via a packet data satellite link. Alternatively, the data may be cached and transmitted in bursts via a circuit or short burst message network, or transmitted after an aircraft has landed via a terrestrial or satellite data link. The system includes connections for computers and enables access to databases on the ground and to electronic mail and the Internet. A GPS receiver is included in the system for recording the aircraft location, while approximate altitude information is available using differential GPS. The system includes a satellite voice terminal to facilitate voice communications and interfaces to headsets and to ordinary telephones.
Prepayment System For Power Distribution Using Rfid Technology

International Classification:
G01R011/56 G06F017/00 G01R021/133
US Classification:
705/412000
Abstract:
A prepayment system for electric power or other utility commodity distribution uses radio frequency identification (RFID) tag technology to store and transfer value (money or KWh) from the retail vendor to the customer, and deliver power to the customer from the power distribution system. The customer purchases power at a retail outlet in the form of a credit to his Card containing an RFID tag. The Card is credited for the amount purchased by the store clerk, using the store's Sales Terminal. The customer takes this Card to his residence or small business and holds it up to the RFID reader/writer sealed into the face of the System Controller. This System Controller is installed at a convenient location near, on or within his premises. Alternatively, he may use an optional Remote Terminal installed inside his premises. In either case, the display associated with the reader/writer indicates to the customer the amount of power remaining. The System Controller then stores the new deposit in the Meter/Contactor associated with the particular customer's circuit. Mounted at the top of the pole, on the building or inside the building, the Meter/Contactor measures usage, decrements the customer's credit, and shuts off power if the credit is depleted.
Wireless Digital Communication System Having Hierarchical Wireless Repeaters With Autonomous Hand-Off
In a wireless communication system, a base unit transmits outgoing TDM signals within a base transmission coverage area at a first frequency. Repeaters in the base coverage area receive the outgoing signal and retransmit it within respective repeater coverage areas at respective frequencies, maintaining the same time slot orientation in TDM format. Several levels of repeaters form a hierarchy covering an expanded range. Remote subscriber units located in a coverage area receive the strongest outgoing frequency signal from a repeater/base unit in a time slot assigned to that unit for a particular call, which time slot is maintained for that call through successive levels of repeaters. Incoming TDMA signals from remote units use the same time slots used in received outgoing signals. The base unit transmits outgoing signals and receives incoming signals at the same frequency, but at different times. Each repeater receives outgoing signals from a lower level repeater (or from the base unit) at the transmission frequency of that lower level repeater, and immediately retransmits the signal in its own coverage at a different frequency.
