摘要:
A system and method for demonstrating or testing operation of on-board diagnostics in a vehicle include imitating performance degradation of a vehicle hardware component and/or associated vehicle system by dynamically modifying at least one control system parameter value associated with the hardware component in response to a request to demonstrate operation of a selected diagnostic function or a specified performance degradation. Embodiments modify at least one control system parameter value associated with the input/output signal of a sensor/actuator to imitate a specified performance degradation. The diagnostics independently monitor operation of various vehicle control systems and operate to detect the degraded performance without knowledge of, or distinguishing between, whether the performance degradation was caused by an actual hardware component, or by the requested modification to the control system parameter value(s) associated with a particular hardware component.

A method for operating an engine having a variable cam timing control system, for controlling a camshaft angle in such engine. The method includes deactivating the variable cam timing system and setting the camshaft angle to a predetermined angle for a predetermined duration after failure in a sensor used to control the variable cam timing system and then reactivating the variable cam timing system after such predetermined time. The deactivating continues during the predetermined duration in the presence of a subsequent failure of the sensor during the predetermined duration. The reactivating comprises driving the cam angle to a camshaft angle established by the variable cam timing system in a predetermined manner. The reactivating occurs over a predetermined reactivation time.

The embodiments disclosed herein is related to a system for optical coherence tomographic imaging of turbid (i.e., scattering) materials utilizing multiple channels of information. The multiple channels of information may be comprised and encompass spatial, angle, spectral and polarization domains. More specifically, the embodiments disclosed herein is related to methods and apparatus for utilizing optical sources, systems or receivers capable of providing (source), processing (system) or recording (receiver) a multiplicity of channels of spectral information for optical coherence tomographic imaging of turbid materials. In these methods and apparatus the multiplicity of channels of spectral information that can be provided by the source, processed by the system, or recorded by the receiver are used to convey simultaneously spatial, spectral or polarimetric information relating to the turbid material being imaged tomographically. The multichannel optical coherence tomographic methods can be incorporated into an endoscopic probe for imaging a patient. The endoscope comprises an optical fiber array and can comprise a plurality of optical fibers adapted to be disposed in the patient. The optical fiber array transmits the light from the light source into the patient, and transmits the light reflected by the patient out of the patient. The plurality of optical fibers in the array is in optical communication with the light source. The multichannel optical coherence tomography system comprises a detector for receiving the light from the array and analyzing the light. The methods and apparatus may be applied for imaging a vessel, biliary, GU and/or GI tract of a patient.

A method of controlling carbonaceous contamination of the surface of a mirror coated with a metal layer comprises the steps of supplying to the mirror a source of carbon for forming carbonaceous deposits on the mirror surface, and a source of a reactant for reacting with the deposits either reductively or by incorporation of hetero-atoms other than oxygen to produce a volatile product, and exposing the mirror to extreme ultra violet (EUV) radiation to activate the reaction. Controlling to the partial pressure ratio of the carbon source and the reactant source can enable the level of contamination of the mirror surface to be actively controlled.

A method for rapid thermal annealing of thin film layers is provided. The method directs a series of pulses or flashes of heat energy toward a targeted layer on a substrate. Each pulse may be at a first temperature range sufficient to anneal the targeted layer, but has a duration that is less than that necessary to render the targeted layer substantially annealed. Moreover, in succession, the series of pulses can incrementally raise the targeted layer to a temperature sufficient for annealing, while minimizing exposure of the remaining layers to the pulses of heat energy. A reactor for implementing the rapid thermal annealing process is also provided.

A method and system for release etching a micro-electrical-mechanical-systems (MEMS) device from a substrate. In one aspect, the invention is a method comprising (a) supporting at least one substrate having a sacrificial oxide and a non-sacrificial material in a process chamber at a pressure and at a temperature; (b) introducing a gas phase mixture comprising a halide-containing species and an alcohol vapor selected from a group consisting of ethanol, 1-propanol, and an aliphatic alcohol having four carbon groups into the process chamber, the gas phase mixture having a volumetric ratio of the halide-containing species to the alcohol vapor of approximately 2 or less; and (c) etching the sacrificial oxide with the gas phase mixture. In another aspect, the invention is a system for carrying out the method.

A method and system for communicating with a managed object. An operator utilizes a user interface tool to initiate communication with the managed object through a server in communication with the managed object. A syntax tree pertaining to the meta data file of the managed object is created in real-time. The syntax tree informs the operator of the required syntax for a command, and parses data entered by the operator for appropriate formatting and presentation. Accordingly, the user interface enables dynamic communication of syntax and response formatting between the operator and the managed object.
摘要:
A Fiber Channel circuit (150) has a Fiber Channel switch (152) that receives data frames on input ports (142) and writes the frames to a data storage device (158) from an output port (156) A port server (162) backs up the frames to a data storage backup device (160) by reading data volumes from the data storage device (158) and writing backup copies of at least some of the read data volumes to the data storage backup device (160) A data monitor (166) receives the frame data from the output port and applies it to the data storage device (158) The data monitor (166) also applies it to the port server (162) The port server (162) identifies frames in the volume that have been changed during the backup process. The identified frames are either reread from the data storage array (158), or from a memory (168) associated with the port server (162), and written to the data storage backup device (160).
