An emergency lighting monitoring and control system controls and monitors the emergency lights in a building. A central control unit automatically schedules self tests for each of the emergency lights and stores the results of the tests in memory. The self tests include tests of the backup power source and the lamp. Some failures are predicted prior to actual failure. Failures are diagnosed and repairs are suggested. Light output is automatically monitored and adjusted. The central control unit generates a report of the self tests and notifies an operator of failures. An operator views test reports, controls the emergency lights, and schedules tests. The system automatically detects newly installed emergency lighting units.

Electronic self-test and/or self-diagnostic systems particularly useful with emergency lighting fixtures, including exit signage having light emitting diodes as light sources and unit emergency fixtures powered with lead-acid batteries, the systems perform testing and diagnostic functions on the circuitry, power supply, charger and lamping of such fixtures either by manual or automatic initiation. Testing functions are provided through use of a programmable microprocessor, the diagnostic circuitry not only monitoring operation of charger/transfer circuitry but also controlling the charger/transfer circuitry to enable alternate strategies for alleviation of a given failure. In emergency mode of a light emitting diode exit sign, a microprocessor-controlled two-stage inverter is employed not only to power the LED light source, but also to efficiently power the microprocessor. Power to the microprocessor is controlled by the microprocessor itself and can therefore be discontinued after appropriate operation until mains power is restored, thereby effectively reducing power consumption to zero. System operation can be flexibly configured through use of a two-wire serial link between modular elements of the system. Incandescent emergency unit fixtures due to high drain rates and output loads require emergency mode operation through use of lead-acid batteries, thereby requiring voltage controlled charging and relay transfer, the self-test and/or self-diagnostic circuitry of the invention used with emergency unit fixtures thus differing in various respects from the circuitry employed for the LED exit signage fixtures and primarily in the need to measure both charge and discharge currents, the circuitry having a larger dynamic range in addition to a capability of measuring both positive and negative currents.

The present invention can guarantee that the constant-current drive unit can output current for driving LEDs to work and light normally even though alternate current fails.

Housings for emergency unit luminaires may be configured to receive both fixed and movable optical assemblies for mounting, allowing for the manufacture of a single housing for production of differing lighting products or lamp assemblies. Additionally, structural elements of a housing may support printed circuit boards, electronics, test devices, and the like, as well as permit electrical connections to be accomplished during assembly of front and back portions of the housing without the need for fasteners requiring tools.

A method and system includes the ability for individuals to set up an ad hoc digital and voice network easily and rapidly to allow users to coordinate their activities by eliminating the need for pre-entry of data into a web or identifying others by name, phone numbers or email. This method is especially useful for police, fire fighters, military, first responders or other emergency situations for coordinating different organizations at the scene of a disaster to elevate conventional communication problems either up and down the chain of command or cross communication between different emergency units. The method and system provides that the users are only required to enter a specific Server IP address and an ad hoc event name, a password and perhaps the name of the particular unit. The system therefore defines the method of accomplishing the ad hoc network by providing all responding personnel that need to communicate with PC's or PDA's which are interconnected to the IP Server using cellular or other communications. Additional communications can be established between users that have RFID tags.

The present invention provides a system and a method for emergency notification that combines the incorporates the RDS/RDBS capability of selected FM radio stations, as well as a specialized addressable receiver with appropriate audio, visual and vibrating signaling capabilities. These elements are combined with a reliable and survivable communications channel to permit activation of the emergency notification signal from a software based tool provided in a command unit. This enables accurate recording of both the status of the emergency units and emergency personnel as well as permits secure notification of the emergency related information to all involved personnel in substantially real-time.

Described is a method of identifying if a subject is to be admitted to the hospital or intensive care unit, the method comprising a) determining the amount of GDF 15 in a sample of the subject, and b) comparing the amount of GDF 15 determined in step a) to a reference amount, whereby a subject to be admitted to the hospital or intensive care unit is to be identified. Also described is a method for predicting the risk of mortality based on determining the amount of GDF 15 in a subject. Also described are devices and kits for carrying out the aforementioned methods.

The invention provides an emergency ballast system which comprises a ballast unit, a signal preparation unit and an emergency unit, wherein the ballast unit is provided with a DC/AC inverter and is used for supplying power to a load which is connected to the emergency ballast system when a common power supply works normally by using the common power supply; the signal preparation unit is connected to the common power supply and is used for detecting the working condition of the common power supply, generating a detection signal for reflecting the working condition of the common power supply and outputting the detection signal to the emergency unit; and the emergency unit comprises an emergency power supply module. When the common power supply has a fault, the emergency unit is used for responding to the detection signal for reflecting the fault, and an emergency power supply which is connected to the emergency unit is used for supplying power to the DC/AC inverter.

The invention belongs to the emergency technology field of nuclear power plants of millions of kilowatts and provides a nuclear emergency unit state diagnosis and accident consequence comprehensive assessment method. According to the method, a nuclear emergency unit is divided into N rings from inside to outside from a reactor core. The method includes the following steps that: whether the secondring breaks is judged, and if the second ring breaks, a next step is executed, otherwise, monitoring is strengthened; whether the breakage occurs in a containment is judged, if the breakage occurs inthe containment, a next step is executed, otherwise, whether the fourth ring to the N-th ring are abnormal is judged; whether abnormal leakage occurs on the third ring is further judged, if abnormal leakage occurs on the third ring, the fourth ring to the N-th ring are directly warned against an abnormality, and monitoring is strengthened; and if the abnormal leakage does not occurs on the third ring, attention is paid to the pressure parameters of the containment until the pressure of the containment reaches a preset value, the leak rate of the containment is set, and from this movement, a warning is given about the abnormality of the fourth ring to the N-th ring, and at the same time, monitoring is strengthened. With the method of the invention adopted, multi-ring joint derivation is realized, automatic error correction can be realized after one ring or a plurality of rings are wrongly misdiagnosed, and therefore, the analysis and early warning of the consequences of nuclear accidents can be greatly enhanced.
