摘要:
Methods and systems for permitting a rendering device, such as a printer, to be automatically configured at the time of device driver installation, regardless of the means utilized to install the driver are disclosed. In general, a device driver (e.g., a printer driver) is associated with the rendering device. The device driver includes a driver default configuration. The driver default configuration can be initially set in the rendering device via an embedded network server (e.g., an embedded web server) in the rendering device. The driver installer can then query the driver default configuration as set on the rendering device. The driver can then be automatically adjusted prior to the installation of the driver, in response to querying the driver default configuration by the driver installer. The rendering device can be implemented as a printer, a scanner, a multi-function device, a photocopy machine, and the like.

A method that allows a space vehicle to determine navigation information represented by the contents of a state vector. The method includes the steps of intermittently receiving navigation signals, initializing the state vector with an estimate of the navigation information, and generating a predicted state vector that represents the predicted values for the navigation information after a predetermined time increment in the future. The method further determines whether a navigation signal has been received within a predetermined window of time from a navigation beacon. If a navigation signal has been received, the method updates the state vector and the contents of the state vector are propagated forward in time to provide an estimate of the navigation information after a predetermined time increment. In some instances, however, a navigation signal is not received within the predetermined window of time. In such situations, the method simply propagates the contents of the predicted state vector forward in time. Thus, the predicted state vector maintains an estimate of the current navigation information even in the absence of a navigation signal.

An autonomous control system supports autonomous operation of the a spacecraft in carrying out mission objective commands. The control system also provides autonomous fault detection, isolation and recovery. Performance problems and anomalies are detected and accounted for in the carrying out mission objectives. A mission manager module analyzes all incoming mission objective commands to verify that sufficient system resources are available and not already dedicated to other pending mission objective commands. A command processor is included to translate acceptable mission objective commands into lower level command sequences for delivery to a flight manager controlling the underlying spacecraft systems. The mission manager reanalyzes all pending mission objective commands whenever unexpected performance or fault conditions are detected. The mission objective commands can be constructed in a hierarchical fashion, with many sequences predefined within the spacecraft. All portions of the autonomous control system, including software and associated data, can be readily replaced, supplemented or disabled at any time before, during or after launch.

A light fixture includes a base on which rests a translucent housing having a pair of end pieces for securing the housing to the base. A pair of mirror image brackets, received by the base, are provided to secure the light fixture to a supporting surface. The brackets are positioned on the surface in a spaced-apart relationship for mating with a backplane of the light fixture. The backplane along with the elements of the light fixture supported thereon, have two rotational orientations supported for mounting on the mirror image brackets. The two rotational orientations provide distinct positional orientations of the light fixture with respect to its supporting surface.

A system for installing a printer driver for a printer connected on a network includes a printer driver for the printer; an installer, located on a host device connected on the network, responsive to activation, for listening for the printer's identification, and responsive to receipt of the printer's identification, for installing the printer driver on the host device; and a beacon, located at the printer, responsive to an input, for broadcasting the printer's identification on the network.
摘要:
A fault identification, isolation and fault recovery system autonomously controls spacecraft operational systems. A fault detection and isolation module monitors the operational systems, identifies faults via such monitoring and attempts to isolate component causing the fault. Isolation may constitute a plurality of hierarchically arranged techniques that enhance speed and maximize the likelihood of identifying a correct hypothesis regarding the actual failure. The fault isolation and fault recovery modules are bounded by a severe fault override module which places the spacecraft operational systems in a safe mode or state. Thus, the override module ensures rapid entry into the safe mode while preventing an erroneous hypothesis serviced by the fault recovery module from driving the system beyond acceptable limits. A high level command processor receives command sequences from remote ground support stations and from the on-board fault recovery module. A ground based test bed attached to a ground support systems is used to generate verified high level fault recovery scripts before and during a mission to bolster fault recovery capabilities.
