Abstract: A method coordinates access points having coverage areas each subdivided into an exclusive sub-area supplemented by an interference sub-area where they overlap and forming part of an optical wireless network. The method includes a procedure including, for each time channel, a first sub-procedure wherein each interface device located in an exclusive sub-area of an access point is allocated an authorized free time slot in the time channel, a second sub-procedure wherein, as long as there remains an interface device without an allocated time slot in an interference sub-area, for each free time slot: a set of interface devices compatible with it is determined, if this set is not empty, an interface device is allocated this free time slot which is compatible with an available access point according to a chosen heuristic, otherwise the time slot is not free, the second sub-step is performed again.

Abstract: A web-based medical diagnostic system predicts diseases via the use of likelihood ratio calculations. Likelihood ratios are multiplied against pre-test odds for diseases to predict post-test odds that will guide a physician to a diagnosis. Each likelihood ratio is calculated on the basis of statistically accrued data and in response to questions and answers directed to patients or test results. Likelihood ratios are scaled infinitely beyond a simple 2×2 matrix, with an independent likelihood matrix created for individual patient responses or test results which are treated as independent variables in the system. The number of predicted diseases and diagnostic outcomes is also infinitely scalable.

Abstract: There is disclosed a process and an apparatus for (1) facilitating patient and professional health care provider interaction and communication about a diagnosis that requires a professional decision, and (2) providing patients with a means for making their own health care decisions by empowering patients with the means for potential self diagnosis of symptoms.
