A smoke detection device main body of a portable smoke detector can switch smoke detection sensitivity. At the start of operation, the smoke detection sensitivity of the portable smoke detector is equal to or higher than a smoke detection sensitivity of a fixed smoke detector that detects smoke in a monitoring area. At this time, switching of smoke detection sensitivity does not work. After the fixed smoke detector detects smoke generation, when the portable smoke detector is used to locate the smoke generation position while moving in the monitoring area, an operation is performed from an initial sensitivity. When a predetermined smoke detection signal is detected while using the portable smoke detector to identify the smoke generation position, the smoke detection sensitivity switching is activated, and the smoke detection sensitivity is changed accordingly. By lowering the smoke detection sensitivity, the smoke generation position is narrowed down and identified.

A sensor measures an environmental factor in an ambient environment immediately surrounding an information handling system. A processor determines that the information handling system is in a first location, provides a first sampling frequency of the sensor based upon the first location, determines that the information handling system is in a second location, and provides a second sampling frequency of the sensor based upon the second location. The first sampling frequency is different from the second sampling frequency.

A reassurance control system and method of use thereof are disclosed herein. The reassurance control system comprising a controller, such as a programmable logic controller, having one or more import ports, wherein each of the one or more ports is assigned a fluid identity. The system further includes a transducer coupled to a fluid and to the controller via a first port having a first fluid identity of the one or more ports. The transducer produces and transmits an identity signal and a pressure signal to the controller. The controller matches the assigned fluid identity of the first port to the identity signal. Wherein responsive to the assigned fluid identity of the first port matching the identity signal, the controller based upon the received identity signal instructs a display to display an identity of the fluid and wherein based upon the received pressure signal displays a pressure of the fluid.

The instructions are further executable to, for each time interval of a plurality of time intervals, determine a GHG emission amount based at least in part on the sensor data and store GHG emission data. The instructions are further executable to receive a request for a set of GHG emission data and in response to the request, output the set of GHG emission data.

An environmental alert system and method for an aerial device including a boom having both insulative and conductive members is disclosed. Temperature, moisture, and humidity sensors are employed on both sides of a location that the boom transitions from being constructed of metal to a dielectric. If environmental data is received indicating the possibility of breakdown in dielectric integrity of the insulative portion due to environmental conditions, warnings are issued to operators.

The present disclosure relates to a method for monitoring and alarming hydrogen leakage of a fuel-cell vehicle and a system thereof. The method comprises the steps of: acquiring the current hydrogen concentration of a fuel-cell vehicle; judging whether the current hydrogen concentration is 0, if not, acquiring the measured hydrogen concentration, the hydrogen pressure drop value and the normal pressure range generated when the current hydrogen concentration of the fuel-cell vehicle is 0; judging whether the hydrogen pressure drop value exceeds the normal pressure range, if so, determining the predicted hydrogen concentration according to the measured hydrogen concentration and the hydrogen pressure drop value; judging whether the predicted hydrogen concentration exceeds the hydrogen leakage alarm threshold, and if not, determining the hydrogen leakage and issuing an alarm. The hydrogen concentration alarm limit can be reached in advance, thereby shortening the time for monitoring and alarming hydrogen leakage.

A data analysis system includes a gas measuring device (2), providing current data and/or historical data, which are stored in a memory (3), and a data processing unit (1). The data includes information on a gas measuring device time of data acquisition. The device transmits data to an interface configured to receive the data and to feed data to the data processing unit and/or to an additional memory (5). A data identification unit (6) is configured to add a specific identifier to the data and add a piece of information on a system time during the data transmission and/or the gas measuring device time during the data transmission. The data processing unit is configured to process the data provided by the gas measuring device and/or by the additional memory such that the system time and the gas measuring device time are taken into consideration.

A process and system analyze data provided by a mobile gas measuring device (3a) for generating an alarm. An alarm management system implements the process and system. The measured data are transmitted to another gas measuring device and/or to a data processing unit (1) and are compared to a limit value. If a limit value violation is detected, an alarm control signal is generated for implementing an instruction for action. A hazard potential is determined and is assigned to the limit value violation in the gas measuring device, the other device, and/or in the data processing unit, taking into consideration weighted influencing variables. Upon a first limit value violation and a second limit value violation being determined, the hazard potentials of these violations are compared and a prioritization is determined based on the comparison. The generation of the alarm control signals is carried out based on the determined prioritization.
