Thousands of process and equipment measurements are gathered by the modern digital process control systems that are deployed in refineries and chemical plants. Several years of these data are historized in databases for analysis and reporting. These databases can be mined for the data patterns that occur during normal operation and those patterns used to determine when the process is behaving abnormally. These normal operating patterns are represented by sets of models. These models include simple engineering equations, which express known relationships that should be true during normal operations and multivariate statistical models based on a variation of principle component analysis. Equipment and process problems can be detected by comparing the data gathered on a minute by minute basis to predictions from these models of normal operation. The deviation between the expected pattern in the process operating data and the actual data pattern are interpreted by fuzzy Petri nets to determine the normality of the process operations. This is then used to help the operator localize and diagnose the root cause of the problem.

The invention relates to a communication system comprising a first and a second communication device, each comprising transmit and receive units for establishing a wireless link between the devices, wherein the first device is a portable listening device. The invention further relates to a method, a data processing system and a medium. The object of the present invention is to control power consumption in a short range wireless link. The problem is solved in that at least the first communication device comprises a control unit for dynamically adjusting the transmit power of its transmit unit based on a measure of the quality of the link, wherein the system is adapted to use the dynamic transmit power regulation to implement a partial power-down mode of the system, when the two communication devices are expected NOT to be in a normal use, wherein the partial power-down mode at least comprises a power-down of the components related to the wireless link. This has the advantage of enabling an adaptation of the power consumption to the current needs. The invention may e.g. be used for wireless communication between (portable) low power devices, e.g. between a pair of hearing instruments.

A method and apparatus for ascertaining the cerebral state of a patient. The method/apparatus may find use in ascertaining the depth of anesthesia of the patient. In one embodiment, the entropy of the patient's EEG signal data is determined as an indication of the cerebral state. A frequency domain power spectrum quantity is obtained from the patient's EMG signal data. The latter quantity can be updated more frequently than the EEG entropy due to its higher frequency. The EEG entropy indication and the EMG power spectrum indication can be combined into a composite indicator that provides an immediate indication of changes in the cerebral state of the patient. In another embodiment, the frequency range over which the entropy of the biopotential signal from the patient is determined is broadened to encompass both EEG signal data and EMG signal data and the entropy so determined used as an indication of the patient's cerebral state.

A method of determining the cause of disease is described, which method uses the detection of “signature” or “fingerprint” volatile compounds in an emission, especially flatus, from a patient.

The present invention relates to a method and apparatus for reducing interference arising from signal propagation delay in multipath signal environments in wireless communication systems. The present invention provides a method of operating a mobile communications base station which receives multipath components of signals from a number of high mobility subscriber terminals, the method comprising: for each subscriber terminal signal received, determining a best signal component; determining the difference in time between reception of said best signal component and a reference time; transmitting to said terminal a transmission timing offset in order to receive said best component at substantially said reference time.

A brake pad measuring tool is disclosed and functions to provide a quick visual indicator for determining brake pad wear condition in motor vehicles. The brake pad measuring tool includes a plurality of rigid bars which are attached in a reciprocal and rotatable manner via a coupling ring. Each of the rigid bars has a free end provided with a color-coded bar segment. The rigid bars also have descending incremental widths which correspond to a specific color cast by each color-coded bar segment, thus serving as a quick visual indicator for pad wear condition. The brake pad measuring tool allows for a brake pad's condition to be determined while the vehicle wheel is still attached to the hub.

A detecting device and a detecting method for monitoring a battery module are provided. The battery module is electrically connected to a load and includes a first battery unit, a second battery unit and a connecting device. The connecting device connects the positive electrode of the first battery unit to the negative electrode of the second battery unit. The detecting device includes a shunt, a voltage detecting module and a control module. The shunt is serial connected between the battery module and the load to measures the load current. The voltage detecting module measures the voltage difference across the connecting device between the positive electrode and the negative electrode. The control module computes the equivalent resistance across the connecting device between the positive electrode and the negative electrode according to the load current and the voltage difference. Therefore, the hazard caused by aging of the electric circuit can be prevented by monitoring the equivalent resistance, which infers the change of the assembly quality.

A splatter indicator sight for use with a firearm taking one or more variables affecting the bullet trajectory under consideration to create a risk zone map of the different zones which can be hit after the user has aimed the firearm at a target. In embodiments of the invention, the boundaries of the most probable hit zones can be quickly indicated to the user by the risk zone map. The risk zone map is illustratively created by projecting a laser beam directly on the target.

The control system (10) utilizes an oxygen sensor (78) to sense an oxygen concentration within a burner exhaust (66) of a fuel processing system (40), wherein the burner device (44) utilizes an anode exhaust stream from a fuel cell (12) to supply heat to a reformer (48). If the anode utilization by the fuel cell (12) anode (14) exceeds an acceptable range, less hydrogen is available for the burner device (44) and more oxygen will therefore be sensed by the oxygen sensor. An oxygen sensor controller (80), in response to the increase in sensed oxygen, increases flow of a fuel feedstock (42) into the reformer (48) to provide more hydrogen fuel to the anode (14) to thereby return anode utilization to an acceptable anode utilization range. An opposite control sequence occurs if anode utilization falls below the acceptable range.
