The system enables business people to understand the impact of business transactions, changes and events in real-time using advanced rules and analytics to filter, categorize and interpret the significance of streams of real-time information. Most business performance analysis today is done manually and this process is a time consuming and skilled task leading to a time delay in producing the analysis. This time lag between the transaction or event happening and being able to take action on the analysis is measured in weeks or months at many companies. By blending real-time information with historical data and performance goals, this system enables business users to assess business events and collaborate within teams to drive optimal business performance. Using forecasting techniques enables business managers to predict the likelihood of achieving a particular goal without relying on manual analysis by a skilled analyst. The system automatically updates the forecast based on real-time changing data, enabling the business manager to have an up to the minute and statistically valid projection of future business performance.

Implantable medical devices (IMDs) for monitoring signs of acute or chronic cardiac heart failure by measuring cardiac blood pressure and mechanical dimensions of the heart and providing multi-chamber pacing optimized as a function of measured blood pressure and dimensions are disclosed. The dimension sensor or sensors comprise at least a first sonomicrometer piezoelectric crystal mounted to a first lead body implanted into or in relation to one heart chamber that operates as an ultrasound transmitter when a drive signal is applied to it and at least one second sonomicrometer crystal mounted to a second lead body implanted into or in relation to a second heart chamber that operates as an ultrasound receiver. The ultrasound receiver converts impinging ultrasound energy transmitted from the ultrasound transmitter through blood and heart tissue into an electrical signal. The time delay between the generation of the transmitted ultrasound signal and the reception of the ultrasound wave varies as a function of distance between the ultrasound transmitter and receiver which in turn varies with contraction and expansion of a heart chamber between the first and second sonomicrometer crystals. One or more additional sonomicrometer piezoelectric crystal can be mounted to additional lead bodies such that the distances between the three or more sonomicrometer crystals can be determined. In each case, the sonomicrometer crystals are distributed about a heart chamber such that the distance between the separated ultrasound transmitter and receiver crystal pairs changes with contraction and relaxation of the heart chamber walls.

System and method are provided where an occupancy sensor with a time delay function designed to dim the lights, for example as a warning, after a first period of time has expired without detecting room occupancy. The lights remain dimmed for a second period of time, and then are turned off after a third period of time has expired without detecting room occupancy. If occupancy is detected during the first period of time, the lights will remain on. If occupancy is detected during the second or third period of time, the lights will be turned on to, for example, previous brightness. A night light can be added to, and/or incorporated in, an occupancy sensor which includes the dimmer feature.

An in-vehicle monitor detects the occurrence of a meta-event related to the operation of a vehicle, such as the vehicle's operation over a maximum allowable speed, operation in a prohibited geographic area, operation during a specific time frame, or combinations thereof. The monitor signals a server via a wireless data link, and the server determines an appropriate deferred action to be taken by an in-vehicle controller, such as disabling the engine, limiting vehicle speed, and locking vehicle doors, upon occurrence of a second meta-event including conditions such as time delays, vehicle speed and direction, and vehicle location. The system can thereby allow orderly and safe control of vehicle functions for purposes such as terminating a pursuit, enforcing legal sentences and operator restrictions, and controlling fleet vehicle operations.

Methods and systems for editing media rich photo projects are disclosed.

A method of seismic surveying comprising the steps of actuating the or each vibrator in a first vibrator group at time T0, and subsequently actuating the or each vibrator in a second vibrator group at time T1 that satisfies T0<T1<T0+S1+L where S1 is the sweep time of the first vibrator group and L is the listening time. At least one of the first vibrator group and the second vibrator group comprises at least two vibrators. The first group and the second group of vibrators may be the same group, or they may be different groups. This method enables the time required to complete a seismic survey to be reduced compared to the prior art “simultaneous shooting” and “slip-sweep shooting” techniques.

In a case where the first group and the second group of vibrators are different, the method may further comprise actuating the or each vibrator in the first vibrator group at time T2, where T1<T2<T1+S2+L and S2 is the sweep time of the first vibrator group, and then actuating the or each vibrator in the second vibrator group at time T3 where T2<T3<T2+S1+L and where T3−T2≠T1−T0. The varying time delay between a shot of the first vibrator group and the corresponding shot of the second vibrator group means that harmonic noise will occur at different times in the shot records so that the noise may be eliminated by appropriately combining the shot records.

The invention relates to a method of preparing signals (X and Y) to be compared to establish predistortion at the input of an amplifier (12), the signals comprising a signal (X) before amplification and a signal (Y) after amplification by said amplifier. Preparation includes time aligning (22) the signal before amplification (X) with the signal after amplification (Y) before using them to establish said predistortion. The invention preferably operates in two stages, namely a stage of coarse time alignment, in which the signal before amplification (X) is subjected to a time delay comprising an integer number of first time units, and a stage of fine time alignment, in which a delay or advance value of a fraction of the first time unit is determined.

A two-dimensional focal plane array (FPA) is divided into sub-arrays of rows and columns of pixels, each sub-array being responsive to light energy from a target object which has been separated by a spectral filter or other spectrum dividing element into a predetermined number of spectral bands. There is preferably one sub-array on the FPA for each predetermined spectral band. Each sub-array has its own read out channel to allow parallel and simultaneous readout of all sub-arrays of the array. The scene is scanned onto the array for simultaneous imaging of the terrain in many spectral bands. Time Delay and Integrate (TDI) techniques are used as a clocking mechanism within the sub-arrays to increase the signal to noise ratio (SNR) of the detected image. Additionally, the TDI length (i.e., number of rows of integration during the exposure) within each sub-array is adjustable to optimize and normalize the response of the photosensitive substrate to each spectral band. The array provides for parallel and simultaneous readout of each sub-array to increase the collection rate of the spectral imagery. All of these features serve to provide a substantial improvement in the area coverage of a hyperspectral imaging system while at the same time increasing the SNR of the detected spectral image.

A method for determining if one audio signal is derived from another audio signal or if two audio signals are derived from the same audio signal compares reduced-information characterizations of said audio signals, wherein said characterizations are based on auditory scene analysis. The comparison removes from the characterisations or minimizes in the characterisations the effect of temporal shift or delay on the audio signals (5-1), calculates a measure of similarity (5-2), and compares the measure of similarity against a threshold. In one alternative, the effect of temporal shift or delay is removed or minimized by cross-correlating the two characterizations. In another alternative, the effect of temporal shift or delay is removed or minimized by transforming the characterizations into a domain that is independent of temporal delay effects, such as the frequency domain. In both cases, a measure of similarity is calculated by calculating a coefficient of correlation.
