Abstract: An Automatic Supplemental Oxygen Control unit, a portable device that automatically monitors and adjusts the flow of supplemental oxygen to the subject in response to the oximetry and other readings derived from sensors attached to the subject and the oxygen source and provides programmed responses to physical inputs from such sensors to provide a closed loop oxygen delivery system.

Abstract: A system and method are disclosed for verifying spare capacity in a communications network comprising a database containing the configuration of switching elements within the network and a plurality of instructions resident on a memory device for operating a control computer, wherein the plurality of instructions includes a code segment for generating alarms on the switching elements, a code segment for receiving the alarms from the switching elements, and a code segment for updating the database to reflect the spare capacity based upon the alarms.

Abstract: A system and method for dynamically restoring communications within a network following an outage comprising a database containing the current configuration of switching elements within the network and a plurality of instructions resident on a memory device for operating a control computer wherein the plurality of instructions includes a code segment for receiving alarms from the switching elements identifying an outage, a code segment for selecting restoration switching elements based upon the configuration of the switching elements in the database, and a code segment for implementing a restoration route utilizing the restoration switching elements to restore communications within the network are disclosed.

Abstract: A method and system for excluding restoral routes from use in bypassing a failed component. Prior to failure of a segment, the restoration system identifies each path in the communications network. A path is a unique sequence of installations that a segment traverses. The restoration system then creates a mapping of the ports of the restoration nodes to the paths of the segments connected to each port. The restoration system then identifies for each path the set of paths that are interdependent. A pair of paths are interdependent when both paths traverse a common pair of installations. Following failure of a segment, the restoration system uses the port on which the failure was detected and uses the mapping to identify the path of the segment that failed. The restoration system then excludes each restoral route that includes a segment that has a path that is interdependent with the identified path.

Abstract: A real-time device data management (RTNDD) system for managing access to data describing devices in a telecommunications network. The RTNDD system maintains a partition data structure for each device. The partition data structure has a header section and a port data section. The header section contains data elements describing the device (e.g., number of ports and device type). The port data section has a port data structure for each port of the device that contains data elements describing the port (e.g., current cross-connect and actual port address for device). The RTNDD system also provides a standard interface through which external systems access the device data. The standard interface has functions for reading and writing to the partition data structures. Each read function reads multiple data elements of a header section or a port data structure at a time, and each write function writes a single data element of a device at a time.
