Current health parameters for a user are monitored at a personal health monitoring system. Current health parameters include multiple monitored physical parameters and multiple monitored environmental parameters. The current health parameters are compared with health allowances for the user. A control signal for transmission to a health control device that controls at least one parameter from among the multiple physical parameters and multiple environmental parameters is determined in response to determining that at least one of the current health parameters exceeds at least one of the health allowances, such that the at least one current health parameter that exceeds the at least one of the health allowances is adjusted by the health control device according to the control signal in order to balance the comprehensive health of the user.

Fiber-optic-based systems and methods for monitoring physical parameters using a remotely deployed circulator are disclosed. In a preferred embodiment the circulator is remotely deployed with respect to an optical source / detector and coupled thereto by two dedicated fiber optical cables: a forward line for passing light from the source through the circulator to fiber-optic-based sensors, and a return line for passing light reflected from the sensors through the circulator back to the detector. By using separate forward and return lines in conjunction with the circulator, backscattering phenomenon experienced on the forward line will not interfere with the reflected light signals coming from the sensors. The circulator, and hence the sensors, may therefore be remotely deployed from the source / detector present at a monitoring station, greatly expanding distances which optical sensing systems can span.

A wireless network having an architecture that resembles a peer-to-peer network has two types of nodes, a first sender type node and a second receiver / relay type node. The network may be used in a medical instrumentation environment whereby the first type node may be wireless devices that could monitor physical parameters of a patient such as for example wireless oximeters. The second type node are mobile wireless communicators that are adapted to receive the data from the wireless devices if they are within the transmission range of the wireless devices. After an aggregation process involving the received data, each of the node communicators broadcasts or disseminates its most up to date data onto the network. Any other relay communicator node in the network that is within the broadcast range of a broadcasting communicator node would receive the up to date data. This makes it possible for communicators that are out of the transmitting range of a wireless device to be apprized of the condition of the patient being monitored by the wireless device. Each communicator in the network is capable of receiving and displaying data from a plurality of wireless devices.

An improved system and method for producing replacement sensor signals for failed sensors, and inferred sensor signals for non-instrumented physical parameters, in processes and equipment having one or more sensors in place for monitoring physical parameters. A data history from a fully-instrumented prototype provides a representative data set of anticipated operating parameters for forming an empirical model in a computer module for generating “virtual” signals for a process or machine in real-time. Replacement or inferential sensor signals can be advantageously used in downstream control processing or analysis. A memory for storing the representative training set, or a transformation thereof, is coupled to a processor. The processor receives from an input data signals embodying real values from sensors actually on the process or machine, and may receive these in real-time. The processor is disposed to take a set of readings of the actual sensors from the input, mid generate an estimate of one or more desired inferred sensors, using a linear combination of the representative training set sensor data, as weighted by the result of a measure of similarity of the input sensor data to the representative training set sensor data.
