A system, computer program product and method including delivering an initial promotion to a customer, determining a status of the initial promotion delivered, selecting a related promotion based on the status of the initial promotion determined, and delivering the related promotion to the customer. The related promotion is selected based on the status of the initial promotion determined by selecting a predetermined related promotion associated with the status of the initial promotion determined. Moreover, the initial and related promotions may be delivered through an electronic or hard delivery medium, and the status of the initial promotion delivered may be determined by determining a status of the initial promotion based on electronic feedback from the customer or based on predetermined status criteria assigned to the initial promotion. Promotions may be delivered primarily through an effective delivery medium for a particular customer which is determined by applying a predetermined effectiveness criteria which includes one of determining the number of occurrences of a predetermined status within a delivery medium and determining the frequency of the customer's use of the delivery medium.

A fuel control system uses a fuel pump powered by a variable speed pump motor controlled by a closed loop electronic feedback system that tracks motor speed and corrects fuel pump motor speed so that the fuel pump delivers flow according to a desired flow schedule based on the pressure feedback from the manifold.

A wavelength selective switch architecture for ROADMs for switching the spectral channels of a multi-channel, multi-wavelength optical signal between input and output ports employs a biaxial MEMS port mirror array for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander for expanding input optical signals to create an elongated beam profile, a diffraction grating for spatially separating the spectral channels, an anamorphic focusing lens system, an array of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The bi-axial channel micromirrors are rotatable about one axis to switch spectral channels between ports, and are rotatable about an orthogonal axis to vary the coupling of the spectral channel to an output port and control attenuation of the spectral signal for complete blocking or for a predetermined power level. The architecture affords hitless switching, near notchless operation, ITU channel alignment, high passband, stability over a broad temperature range, and minimum insertion loss through the optimal optical coupling efficiency enabled by the feedback control system.

In nuclear magnetic resonance experiments, Cartesian electronic feedback is used to reduce substantially in transmission and / or reception the deleterious effects of sample-mediated and direct interactions between coils in an array of transmitting and / or receiving coils. The feedback is also used with single or multiple coils to maintain at essentially constant values the relationship between an input transmitter voltage and the magnetic resonance flip angle, and the relationship between transverse nuclear magnetisation and the strength of the free induction decay signal presented by a receiver for analysis, regardless of factors such as sample electrical conductivity.

The field of the invention is that of light boxes used for illuminating optical-valve displays, especially matrix liquid-crystal displays (or LCDs). The illumination from light boxes can at the present time be produced by light-emitting diodes that emit in various spectral bands so as to reconstruct white illumination. For a number of applications, in particular aeronautical applications, it is necessary to maintain the photometric and colorimetric characteristics of this illumination independently of the environmental and ageing conditions of the components. The invention provides an electronic feedback control device for maintaining the photometric and colorimetric characteristics of this illumination at given setpoint values without introducing disturbing optoelectronic devices into the light box. Several possible technical solutions are described.

A hearing aid device (2) is disclosed. The hearing aid device (2) is configured to be sealingly inserted into the bony region (20) of the ear canal (16). The hearing aid device (2) comprises a receiver (12) and at least one microphone (4, 6) and means for processing sound signals detected by the at least one microphone (4, 6). The hearing aid device (2) comprises means for carrying out electronic feedback suppression by applying a frequency shift (ΔF) and / or a time delay to the detected sound signals. A method for providing electronic feedback reduction in a hearing aid device (2) is also disclosed.

A replacement handle for rowing exercise machines. The rowing machine handle described herein is a simple tool which can be added to existing machines to give the user greater feedback and control over training and exercise sessions, on a variety of rowing exercise machines, than is currently available. It is easy to use, and with included applications for mobile devices will help the user to create more effective training sessions and training programs. Said rowing machine handle can be used effectively by a wide range of users. Current rowing machine handles do not provide electronic feedback about the rowing motion or exercise performance. The above replacement handle will provide direct and immediate feedback to the user about his exercise session, including information about his rowing motion (technique) and his exercise performance (physiology).
