Definitions

  • the present invention relates to a digital situation indicator, especially a personal monitoring and alarm system as defined in the preamble of claim 1.
  • firefighters When entering a burning building, firefighters wear breathing apparatus consisting of an air tank, regulator, facemask and pressure gage. Typically, firefighters work in dense smoke, where the visibility may be only a few inches.
  • Firefighters carry a personal alert safety system (PASS) device, which activates an audible alarm, if they stop moving.
  • the PASS device has a "Pre- Alert” stage, which allows the firefighter a pre-specified number of seconds to move or to shake the PASS device, before the alarm is activated.
  • PASS personal alert safety system
  • firefighters need to know certain information about their constantly changing situation in order to safely and efficiently perform their work.
  • the firefighter also needs to know the ambient temperature, its time-dependent effect on his or her cumulative heat stress level, and whether flashover conditions are impending.
  • the firefighter Before opening a door inside a burning building, the firefighter needs to know whether there is a raging fire on the other side.
  • firefighters typically have to use axes to inspect inside walls, to ensure that no hidden fires exist.
  • Firefighters wear thick gloves, carry axes and water hoses, and need their hands free to be able to perform their work. Gages that attach to the air hose and hang from the firefighter's side are inconvenient to continuously pick-up and, in dense smoke, are almost impossible to read.
  • a helmet-mounted display system such as those used by military jet fighter pilots, which projects data onto the visor of the helmet, would offer firefighters a possible solution.
  • the cost of a single helmet could absorb an annual budget.
  • the cost to equip all firefighters worldwide would be staggering.
  • welders Another occupational group working with impaired visibility are welders.
  • certain amperage settings for the welds may be specificated in the manufacturing drawings, and it is necessary to the welder from time to time to check the amperage gage.
  • the welder has to work severeral meters away from the welding machine, and he has to flip up his helmet and walk back to read the gage. If the welder is working on a ladder or a scaffold, he has to climb down or ask someone else to read the amperage.
  • warfighters suffer from impaired visibility when chemical warfare agents (CWA) are present and they have to wear gas masks and protective clothing. Sometimes warfighters have to work in even more impaired visibility conditions, for example after a bombardment the battlefield is covered with smoke.
  • CWA chemical warfare agents
  • Warfighters carry CWA detection instruments, which indicate the presence of any chemical warfare agent.
  • the CWA detection instrument detects the presence of CWA, it activates an audible alarm, and warfighters put on their gas masks and protective clothing.
  • the CWA detection instrument continues to monitor the level of present CWA, and informs the warfighter when it is safe to take of the gas mask.
  • the CWA detection instrument also continuously measures the concentration of chemical warfare agents in the surrounding. To be all the time aware of the current concetration, warfighters need to look at the instrument frequently. Current instruments are handheld and warfighters need pick them up to read them, same time forcing him to release grip from his tools or weapon.
  • Displays of these current handheld instruments are small and they are not protected from mud and dirt. Also dense smoke can impaire the readability of the instrument. To improve the readability of these current CWA detection instruments their displays are often illuminated. This inturn can reveal the warfighter to the enemy. One detection instrument is also needed for each warfighter, which adds weight to the warfighter' s gear and increases costs.
  • the incident commander is in charge of all firefighters at the scene of the fire. Each firefighter gives the IC a personal accountability tag (PAT) upon arrival at the scene.
  • PAT personal accountability tag
  • the IC keeps track of the firefighters by the use of a unit identification pad (UIP) and a large marker board.
  • UIP unit identification pad
  • the drawback is that once the firefighters are inside the fire, the IC has no method of knowing how much air each firefighter has left, what temperature the firefighters are operating in, what is their heat stress level or PASS device status.
  • the commanding officer (CO) of a certain part of the battlefield is tracking the overall CWA concentration of that area. Warfighters report their instrument readings to the CO either using a radio or a courier.
  • the drawback is that the CO can not keep track of the CWA concentration or the dosage of an individual warfighter in realtime.
  • Firefighters, welders and warfighters are just examples for possible users of digital situation indicator of the invention. This kind of indicators can be utilised in many fields where personal monitoring and alarming are essential.
  • a primary object of the present invention is to provide a digital situation indicator, especially a personal monitoring and alarm system that will overcome the shortcomings of the prior art devices.
