A gas monitor configured to monitor at least one target gas in an environmental mixture, by separating and concentrating the target gas and then adjusting for the concentration factor. The adjustment may also take into account sensor sensitivities to other gases. Methods for adjustment of target gas results and increasing accuracy of monitoring are described.

The invention relates to a personal sensing device (1A, 1B) to be worn by a person (2A, 2B) on a site (3), comprising: a gas sensor (4) for measuring a gas concentration of a gas; a communication system (5) for communicating an alarm/event or operational condition, such as the gas concentration, to a computer system (6), wherein the computer system (6) is arranged for processing the communicated alarm/event and/or triggering an alarm/response in response to the communication of the operational condition, for instance when the computer system determines that the gas concentration exceeds a pre-determined limit; characterised in that the computer system (6) is configured for distribution, preferably intelligent distribution, of one or more alarm/event instructions in response to the alarm/event or operational condition.

An extension cord includes a plurality of electrical conductors. A plug is configured to electrically couple a first respective end of the plurality of electrical conductors with an electrical receptacle of a power source. An outlet assembly is coupled with a second respective end of the plurality of electrical conductors. The outlet assembly may include one or more outlet receptacles configured to provide electrical power from the power source. A power meter may be configured to measure an electrical draw through the outlet assembly and to provide a user perceptible output based upon the measured electrical draw. A carbon monoxide monitor may be configured to detect an environmental carbon monoxide level proximate the outlet assembly and to provide a user perceptible indication when the detected environment carbon monoxide level exceeds a threshold.

A wireless sensing device for environmental monitoring of a location is provided. The sensing device includes an electronic system and a housing for securing and protecting the electronic system in a cavity therein. The housing includes a vented top portion defining the cavity, and a wicking base portion including wicking material attached to and covering an exposed underside of the top portion. The electronic system includes: a temperature and humidity sensor for sensing a current temperature and humidity of the location and converting the sensed temperature and humidity to temperature and humidity signals; a wireless transmitter for periodically wirelessly transmitting the temperature and humidity signals from the location to an external computing device; an alerting device for providing an audible, visual, or tactile signal from the location in order to alert a user of a condition of interest; and a microcontroller for controlling the electronic system devices.

The present invention relates to a smart gas monitoring system configured at a confined space. The smart gas monitoring system measures concentration of hazardous gases at regular intervals and generates an alarm if concentration of a gas increases beyond a pre-defined value. The smart gas monitoring system also generates an alert to a number of laborers on their electronic devices, along with measuring their health conditions.

A watercraft safety lighting system includes one or more light sensors for measuring ambient light levels, which are operatively connected to an electronic controller, such as a programmable logic controller or any suitable programmable computing device. The navigation lights are operatively connected to the electronic controller, as well as docking lights, interior lights, and instrument panel lighting, such as the lighting for gauges, instrument panels, video screens, GPS monitors, and the like. When ambient light levels reach a predetermined level of low light (as darkness is setting in, for example), the electronic controller is programmed to switch on the navigation lights, and to adjust other lighting to appropriate levels for night-time operations. The system may also shut off docking lights at a predetermined speed after dark, and may include alarms to warn the boat captain of improper lighting settings in low-light conditions.
