摘要： The present invention relates to a general purpose interface to a Fibre Channel array controller, more particularly to a gigabit interface converter (GBIC) or a gigabit link module (GLM) channel adapter, and to the use of a channel controller with associated general GBIC/GLM adapters to provide an ultra-high bandwidth bus. Specifically, the present invention provides an array controller. The array controller through programmable functionality causes a plurality of devices to appear as a single device. Moreover, the array controller provides a plurality of general purpose interfaces to allow connection of a plurality of heterogeneous devices. Thus, the present invention may allow an integrated storage system comprising disk drives, tape-units, CD-ROMs, optical drives, and/or the like. Alternatively, the array controller may be programmed to implement bus protocols. Thereby, the array controller may provide an ultra-high bandwidth bus by utilizing Fibre Channel connections and optical interfaces for connected devices.

摘要： Pattern detection methods and arrangements are provided for monitoring a Fibre Channel, a Gigabit Ethernet, or other like data stream for programmable trigger patterns. Upon detecting a trigger pattern, the pattern detection methods and arrangements will assert an output. The output is useful for triggering oscilloscopes to be able to properly display the signal and more importantly, for arming time interval analyzers and other like test instruments. The pattern detection methods and arrangements are capable of dealing with elasticity in the data transmission channel. For example, the trigger pattern can be uniquely configured to a frame header or frame contents and the test instrument can be set to limit its sampling to within the frame bounds. In this manner all of the variability of fill transmission words appearing or disappearing essentially becomes transparent to the test instrument.

摘要： The present invention involves hierarchical storage controllers which enable a scalable storage system. The scalable storage system is capable of causing a very large amount of discrete disk units to appear as a single drive. The scalable storage system is organized into a hierarchical structure by providing a series of disk arrays in parallel with a controller via Fiber Channel connections to form a “virtual disk.” The next level in the hierarchical structure is created by connecting a number of virtual disks and a higher level controller in parallel via higher bandwidth connections. This next assemblage of devices is configured to appear as a single drive. Also, the scalable storage system disposes increasingly sized RAM caches to increase system performance. Moreover, wave division multiplexing (WDM) may be utilized to communicate with a file server via a highest level controller.

摘要： With reference to FIG. 1, an active sound control system comprises a loudspeaker LS having an input qs and operable to generate sound waves for interference with unwanted sound so as to produce a region close to the user of the system in which the perceived sound is substantially reduced. A monitoring microphone ro is positioned closer to the loudspeaker LS than to the region of sound reduction. Loudspeaker control means for controlling the input qs to the loudspeaker LS operate to energise the loudspeaker such that the sound waves emitted by the loudspeaker substantially cancel the unwanted sound waves in said region. The loudspeaker control means includes a signal processing means (FIG. 3) arranged to simulate a microphone output that would be obtained if that microphone, instead of being positioned closer to the loudspeaker LS than the user, were to be positioned in a notional position ra relatively close to the user. The resulting simulated or virtual microphone output is then used to control the signal fed to the loudspeaker input qs.

摘要： To reduce noise inside a motor car passenger compartment, two loudspeakers 37.sub.1, 37.sub.2 are driven by signals derived from a reference signal x(n) by adaptive filtering carried out by a programmed microprocessor and memory unit 36 which adapts the filtering in dependence on error signals e.sub.l (n) from four microphones 42.sub.1, 42.sub.2, 42.sub.3 and 42.sub.4 distributed in the passenger compartment. Reference filtering coefficients are initially determined by analysis of finite impulse responses when white noise is acoustically coupled from the loudspeakers 37 to the microphones 42, a white noise generator 48 being coupled to the unit 36. The reference signal x(n) is restricted to one or more selected harmonics or subharmonics of the fundamental noise frequency by a filter 34 which tracks the selected frequency. The selected frequency may be obtained from a coil 31 in the ignition circuit of the vehicle.

摘要： In propeller of fan driven aircraft, cabin noise levels may be reduced by adjustment of the phase relationship between a reference propeller or fan and some or all of the other propellers or fans. An aircraft cabin (1) contains four microphones and two loudspeakers which form the active elements of a noise control system. The microphone outputs are fed via amplifiers to a digital signal processor (11) having an adaptation algorithm in a memory store. The processor generates an error signal which is used to adjust the synchrophase angle between the reference propeller and a synchrophased propeller, controlled by a synchrophaser. Thus the synchrophase angle is varied dynamically during flight to minimize propeller noise in the cabin over a range of flying conditions.
