Appl. No.:

13/368131

Assignee:

Telcordia Technologies, Inc. - Piscataway NJ

International Classification:

H04L 12/28
H04B 7/185
H04W 4/00
H04N 7/20

US Classification:

370400, 455 121, 455427, 725 63

Abstract:

In a distributed management scheme for LEO satellite networks interactions between a satellite and the designated fixed center occur according to a time schedule and only when the designated center is in the coverage area of the payload. For exception/alarm reporting and real-time configuration updates the interaction varies with time. Interactions of this type occur between a satellite and the management center that is “nearest” to the payload or satellite at the time instant at which the network event occurs or configuration upload is needed. The nearest management center for a payload is the center that can be reached from the payload with fewest number of crosslink hops. A central network operation center determines, prior to payload launch, the association between satellites and management centers for routine information exchange, and the nearest management center for the payload for different snapshots of time.

International Classification:

H04W 28/02

US Classification:

370225

Abstract:

A payload switching architecture for LEO satellite networks minimizes processing and storage requirements of payloads for deployment as small primary or secondary payloads, payloads perform only forwarding functions. Forwarding rules are provisioned in the payloads enabling them to reroute in case of failures or congestion without intervention from a ground station. Configuration rules are provisioned in the payloads enabling them to dynamically establish and remove interplane crosslinks without intervention from a ground station. The central network operations center on the ground computes forwarding rules and configuration rules for payloads and uploads the rules to the payloads.

International Classification:

H04L 12/26

US Classification:

370238

Abstract:

In Low Earth Orbit (LEO) satellite networks data routes for point to point and point to multipoint communication sessions in LEO satellite networks are determined by considering session bandwidth, priority, and the constantly changing terminal-satellite and satellite-satellite connectivity. Multiple routes are computed for a session to facilitate automatic adaptive rerouting by satellite payloads when they encounter network failures or congestion conditions.

International Classification:

B41J 508

US Classification:

400474

Abstract:

A low profile keyboard operating system in which a generally orthogonal matrix of mechanically movable row and column matrix members is disposed over the keyboard to be operated with the intersections of the matrix members adjacent to the keys, the arrangement being such that actuation of only one member at an intersection will not operate a key while operation of both members at an intersection actuates a key.

Inventors:

Avi Arad - New York NY
William Stephens - Hicksville NY

International Classification:

B05B 724

US Classification:

239315

Abstract:

An apparatus is provided which is adapted to be connected in communication with a single stream of water and which is constructed and arranged to divide the single stream of water into a plurality of streams of water. The apparatus defines a fluid stream through a fluid chamber into a mixing chamber and forms the plurality of streams by directing the water through a foraminous nozzle member. The apparatus also includes an additive chamber adapted to contain an additive and includes provision for mixing some of the water with the additive in the additive chamber and supplying the mixture of additive and water to the mixing chamber for formation, along with the plain water, into a plurality of streams of water through the foraminous nozzle, each containing the same amount of additive. The apparatus includes means for selectively controlling the introduction of water mixed with additive into the mixing chamber through rotation of the foraminous nozzle between normal and additive-blocking positions.

Appl. No.:

8/093447

Inventors:

William G. Stephens - Milwaukee WI

International Classification:

F04B 200

US Classification:

156 71

Abstract:

A method for the prevention of fire caused by the application to a flammable substratum of a modified bitumen roofing membrane involving concurrent flame heating of the roofing material and substratum during application. The method comprises applying an aqueous solution of fire retardant chemicals to all flammable surfaces to be roofed and adjacent thereto prior to the flame heating of the modified bitumen membrane and the substratum. The fire retardant solution may be applied by a variety of application techniques on the job site or to the roof components prior to construction assembly. Preferred fire retardant formulations and rates of application are disclosed.
