Signal processing apparatus.

Abstract: The present invention involves method and apparatus for analyzing two measured signals that are modeled as containing primary and secondary portions. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, the present invention involves utilizing a transformation which evaluates a plurality of possible signal coefficients in order to find appropriate coefficients. Alternatively, the present invention involves using statistical functions or Fourier transform and windowing techniques to determine the coefficients relating to two measured signals. Use of this invention is described in particular detail with respect to blood oximetry measurements.

Signal processing apparatus and method

Abstract: A method and an apparatus to analyze two measured signals that are modeled as containing desired and undesired portions such as noise, FM and AM modulation. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, a transformation is used to evaluate a ratio of the two measured signals in order to find appropriate coefficients. The measured signals are then fed into a signal scrubber which uses the coefficients to remove the unwanted portions. The signal scrubbing is performed in either the time domain or in the frequency domain. The method and apparatus are particularly advantageous to blood oximetry and pulserate measurements. In another embodiment, an estimate of the pulserate is obtained by applying a set of rules to a spectral transform of the scrubbed signal. In another embodiment, an estimate of the pulserate is obtained by transforming the scrubbed signal from a first spectral domain into a second spectral domain. The pulserate is found by identifying the largest spectral peak in the second spectral domain.

Progressive skyline computation in database systems

Abstract: The skyline of a d-dimensional dataset contains the points that are not dominated by any other point on all dimensions. Skyline computation has recently received considerable attention in the database community, especially for progressive methods that can quickly return the initial results without reading the entire database. All the existing algorithms, however, have some serious shortcomings which limit their applicability in practice. In this article we develop branch-and-bound skyline (BBS), an algorithm based on nearest-neighbor search, which is I/O optimal, that is, it performs a single access only to those nodes that may contain skyline points. BBS is simple to implement and supports all types of progressive processing (e.g., user preferences, arbitrary dimensionality, etc). Furthermore, we propose several interesting variations of skyline computation, and show how BBS can be applied for their efficient processing.

Method and system for processing internet payments using the electronic funds transfer network

Abstract: A system and method for effectuating Electronic Funds Transfer credit messages. The main structural components of the system include a Payment Portal Processor (PPP), an Internet Pay Anyone (IPA) Account, a Virtual Private Lockbox (VPL) and an associated Account Reporter, the existing EFT networks, and a cash card for accessing a VPL or IP account. The PPP is a software application that provides a secure portal for accessing (linking to) either the user's Demand Deposit Account (DDA) or an IPA account and can be combined with the functionality of a traditional digital Wallet. Consumers use a PPP enhanced Wallet to fund their account, shop on the web, pay bills, pay anyone, store electronic receipts and transaction history, and check their recent PPP enhanced Wallet activity. The IPA account is a special purpose account with limited functionality for making electronic payments in the form of EFT credit messages. The VPL is a limited function receive only account for receiving electronic payments through the EFT. The Account Reporter is a portal to view transaction history and balance of IPA and VPL accounts, provide online, real-time transaction reports, and to reconcile accounts receivable/purchase records against incoming EFT payment records. A physical card can be associated with either an IPA or VPL account in order to provide PIN debit capability.

Organizational culture and knowledge sharing: critical success factors

Abstract: Purpose – This research aims at investigating the role of certain factors in organizational culture in the success of knowledge sharing Such factors as interpersonal trust, communication between staff, information systems, rewards and organization structure play an important role in defining the relationships between staff and in turn, providing possibilities to break obstacles to knowledge sharing This research is intended to contribute in helping businesses understand the essential role of organizational culture in nourishing knowledge and spreading it in order to become leaders in utilizing their know-how and enjoying prosperity thereafter Design/methodology/approach – The conclusions of this study are based on interpreting the results of a survey and a number of interviews with staff from various organizations in Bahrain from the public and private sectors Findings – The research findings indicate that trust, communication, information systems, rewards and organization structure are positively related to knowledge sharing in organizations Research limitations/implications – The authors believe that further research is required to address governmental sector institutions, where organizational politics dominate a role in hoarding knowledge, through such methods as case studies and observation Originality/value – Previous research indicated that the Bahraini society is influenced by traditions of household, tribe, and especially religion of the Arab and Islamic world These factors define people’s beliefs and behaviours, and thus exercise strong influence in the performance of business organizations This study is motivated by the desire to explore the role of the national organizational culture on knowledge sharing, which may be different from previous studies conducted abroad
