| 20090187381 | Novelty detection - A method and apparatus for detecting an abnormality in e.g. in operating characteristics or function of a machine, apparatus or system, the method including providing a data sample set comprising n values of a measured physical parameter associated with the apparatus or system generated by repeating a measurement of the physical parameter n times. An extremal measured parameter value is selected from amongst the data sample set, determining a probability of observing the selected parameter value (e.g. of observing a value not exceeding the selected parameter value) by applying the selected parameter value to an extreme value probability distribution function having a location parameter and a scale parameter. The value of the location parameter and the value of the scale parameter are each constructed using an integer value m (e.g. notionally representing the size of a sub-sample data set comprising m of said measured parameter values) in which m is less than n (i.e. m| 07-23-2009 | |

| 20100014761 | Methods And Systems For Discriminating Bands In Scalograms - The present disclosure is directed towards embodiments of systems and methods for discriminating (e.g., masking out) scale bands that are determined to be not of interest from a scalogram derived from a continuous wavelet transform of a signal. Techniques for determining whether a scale band is not of interest include, for example, determining whether a scale band's amplitude is being modulated by one or more other bands in the scalogram. Another technique involves determining whether a scale band is located between two other bands and has energy less than that of its neighboring bands. Another technique involves determining whether a scale band is located at about half the scale of another, more dominant (i.e., higher energy) band. | 01-21-2010 |

| 20090324034 | SYSTEMS AND METHODS FOR RIDGE SELECTION IN SCALOGRAMS OF SIGNALS - According to embodiments, systems, devices, and methods for ridge selection in scalograms are disclosed. Ridges or ridge components are features within a scalogram which may be computed from a signal such as a physiological (e.g., photoplethysmographic) signal. Ridges may be identified from one or more scalograms of the signal. Parameters characterizing these ridges may be determined. Based at least in part on these parameters, a ridge density distribution function is determined. A ridge is selected from analyzing this ridge density distribution function. In some embodiments, the selected ridge is used to determine a physiological parameter such as respiration rate. | 12-31-2009 |

| 20120035885 | METHOD AND APPARATUS FOR MONITORING AND ANALYZING VIBRATIONS IN ROTARY MACHINES - Vibration amplitudes are recorded as a function of rotation speed and of frequency and the data is analyzed to estimate a noise floor amplitude threshold for each of a plurality of different speed and frequency sub-ranges. On the basis of training data known to be normal speed-frequency areas which contain significant spectral content in normal operation are deemed “known significant spectral content”, so that during monitoring of new data points which correspond to significant vibration energy at speeds and frequencies different from the known significant spectral content can be deemed “novel significant spectral content” and form the basis for an alert. The estimation of the noise floor is based on a probabilistic analysis of the data in each speed-frequency area and from this analysis an extreme value distribution expressing the probability that any given sample is noise is obtained. | 02-09-2012 |

| 20110241782 | POWER AMPLIFIER - A power amplifier comprises a series stack of power amplifier devices, connected in parallel to the amplifier input for receiving an RF input signal, and having output terminals being connected in series to the amplifier output. An intermediate coupling capacitor is connected between each adjacent pair of power amplifier devices in the series stack of power amplifier devices for DC isolation of said power amplifier devices. This reduces the required DC supply voltage, as well as allowing shorting of individual power amplifier devices in response to variation in the DC supply voltage. | 10-06-2011 |

| 20120089874 | DIAGNOSING ENTITIES ASSOCIATED WITH SOFTWARE COMPONENTS - In one embodiment, a system includes a recording module adapted for recording event history information for one or more events associated with an entity, an evaluating module adapted for evaluating the event history information for each of the one or more events associated with the entity against a symptom rule, wherein the symptom rule defines a validity state of a diagnosis, an issuing module adapted for issuing a subscription to one or more subscribers, wherein the subscription enables the one or more subscribers to receive diagnosis information, and an indicating module adapted for indicating the validity state of the diagnosis to the subscriber, wherein the recording module and the evaluating module are independent such that the issuing module and the event history information are substantially decoupled. Other systems, methods, and computer program products are also described, according to various embodiments. | 04-12-2012 |

| 20100011177 | METHOD FOR MIGRATION OF SYNCHRONOUS REMOTE COPY SERVICE TO A VIRTUALIZATION APPLIANCE - A method, system, computer program product, and computer program storage device for receiving and processing I/O requests from a host device and providing data consistency in both a primary site and a secondary site, while migrating a SRC (Synchronous Peer to Peer Remote Copy) from a backend storage subsystem to a storage virtualization appliance. While transferring SRC from the backend storage subsystem to the storage virtualization appliance, all new I/O requests are saved in both a primary cache memory and a secondary cache memory, allowing a time window during which the SRC at the backend storage subsystem can be stopped and the secondary storage device is made as a readable and writable medium. The primary cache memory and secondary cache memory operates separately on each I/O request in write-through, read-write or no-flush mode. | 01-14-2010 |
