Filed:

Sep 7, 2000

Appl. No.:

09/657258

Inventors:

William P. Brown - Bellevue WA, US
Michael B. Mathews - Kirkland WA, US

Assignee:

YottaYotta, Inc. - Edmonton

International Classification:

G06F011/00

US Classification:

714 6, 714 5, 714 9, 714 11, 714 12

Abstract:

Multiple Array Management Functions (AMFs) are connected to multiple redundancy groups over a storage area network (SAN), such as a fiber-channel based SAN. The multiple AMFs share management responsibility of the redundancy groups, each of which typically includes multiple resources spread over multiple disks. The AMFs provide concurrent access to the redundancy groups for associated host systems. When a host requests an AMF to perform an operation on a resource, the AMF synchronizes with the other AMFs sharing control of the redundancy group that includes the resource to be operated on, so as to obtain a lock on the resource. While performing the operation, the AMF send replication data and state information associated with the resource such that if the AMF fails, any of the other AMFs are able to complete the operation and maintain data reliability and coherency.

US Classification:

701209, 701200, 701201, 701213, 340995

Abstract:

The present invention provides for distributed navigation and route guidance using networked computing devices. A computing device may host one or more navigation functional components. The location of a navigable object is sensed and communicated to associated navigation components in a communication network. The navigation components collectively provide guidance information to a navigable object controller. A navigable object controller directs the movement of an navigable object using guidance information to keep it on a specified route. The navigable object controller interacts with the distributed navigation system through an interface, which provides the appropriate presentation of guidance information and functions for the particular type of navigable object controller (e. g. , human-machine interface, or system to system). The present invention provides the structures and methods for a flexible navigation and guidance system supporting a variety of network capabilities and computing devices using the same software implementation.

US Classification:

718104, 718102, 709201, 709202

Abstract:

The system and methods of the present invention provide a processing function that is useful for controlling any type of transaction between providers and consumers of information services. The invention provides a transaction framework that dynamically integrates a plurality of service providers and consumers based on transaction context data. Transactions between services are described using a transaction definition. A transaction definition specifies the details of the transaction using a uniform specification model, where services are classified through a standardized taxonomic structure. The processing function analyzes service classification during a transaction to determine the appropriate configuration and processing strategy.

Peter F. MacDoran - Sanford FL, US

Assignee:

Loctronix Corporation - Woodinville WA

International Classification:

H04B 7/185

US Classification:

34235714

Abstract:

The present invention relates to a system and method for providing location determination in a configured environment in which Global Navigation Satellite System Signals may not be available. In this regard, local beacon systems generate spread spectrum CDMA signals that are received by spectral compression units that derive physically meaningful observations without a requirement for correlation of the intercepted energy by means of the known spreading codes. The invention can coexist with communication assets already in place, and the design allows for self calibration, which simplifies installation and usage. The invention has utility in applications in which GNSS signals are unavailable or limited, for example, in warehouse inventory management, in search and rescue operations and in asset tracking in indoor environments.
