Description

451 221 2 Tack vare störundertryckningen'genom bi a en differentieiï mätmetod, är det också möjiigt att genomföra dylika mätningar i vaniig inomhus- miijö med 50/60 Hz fäit etc. 451 221 2 Thanks to the noise suppression by a different measurement method, it is also possible to carry out such measurements in a standard indoor environment with 50/60 Hz fäit etc.

En SQUID innebär sâiedes en möjiighet att direkt via magnetfäït samman- länka en människa och en apparat. f» Genomeatt-appiicera känd teknik nämiigen hypersensitiva magnetometrar (typ SQUID) päflëet kiassiska probiemet med siummerövervakning, t ex genom att ha en sådan detektor monterad i biitaket ovanför förarpïatsen, är det möjiigt att åstadkomma en ny typ av siummerdetektor viiken både är praktisk för användaren och omedeibar och exakt i sitt svar.A SQUID means that it is possible to link a human being and an apparatus directly via magnetic force. By applying known technology, namely hypersensitive magnetometers (type SQUID) to the chiase probiem with siummer monitoring, for example by having such a detector mounted in the ceiling above the driver's seat, it is possible to provide a new type of siummer detector using both and omedeibar and exactly in his answer.

Priset för en SQUID, idag åtminstone, är dock antagiigen tyvärr för högt för massappiikation.However, the price for a SQUID, today at least, is probably too high for mass application.

Emeiiertid pâgâridagett intensivt forsknings- och utveckiingsarbete inom sensor-teknik och häribiand då även magnetometrar. Därför existerar det faktiskt också idag, på prototypstadiet, magnetometrar viika bygger på en kombination av fiberoptik och nya, magnetostriktiva legeringar viika har en kansiighet på 1u'12 - 1o'13 iesia. penna känsiighet bör 1 princip räcka för siumerdetektering och troïigt pris på denna typ av magnetometer är mycket iågt.Emeiiertid has been conducting intensive research and development work in sensor technology and this includes magnetometers. Therefore, in fact, even today, at the prototype stage, magnetometers viika are based on a combination of fiber optics and new, magnetostrictive alloys viika have a probability of 1u'12 - 1o'13 iesia. pen sensitivity should 1 principle suffice for siumer detection and troïigt price of this type of magnetometer is very low.

Därför är det rimiigt att anta att inom en nära framtid en siummerdetektor av här beskriven typ skuiie kunna göras tiiigängiig för massappiikationer. fal (f.Therefore, it is reasonable to assume that in the near future a siummer detector of the type described here may be made available for mass applications. fal (f.

451 221 PATENTKRAV451 221 PATENT REQUIREMENTS 1. Sätt vid detektering av insomning, k ä n n e t e c k n at av att en hypersensitiv magnetometer (typ SQUID) anbringas på detekteringsavstånd i närheten av den person som skall slummer- övervakas, varvid den signalbild, som de svaga magnetfälts-u variationerna i personens hjärna ger upphov till, kontinuer- ligt detekteras, - att förloppet för den detekterade signalbilden, i en signal- behandlingsenhet jämföres med ett signalförlopp som är karak- täristiskt för insomning/medvetslöshet, - att en förutbestämd likhet mellan detekterat signalbilds- förlopp och det för insomning/medvetslöshet karaktäristiska signalbildsförloppet bringas ge upphov till en signal, som påkallar personens uppmärksamhet.A method of detecting insomnia, characterized in that a hypersensitive magnetometer (type SQUID) is placed at a detection distance in the vicinity of the person to be monitored, the signal image given by the weak magnetic field variations in the person's brain caused, is continuously detected, - that the course of the detected signal image, in a signal processing unit, is compared with a signal sequence which is characteristic of insomnia / unconsciousness, - that a predetermined similarity between detected signal image sequence and that of insomnia / Unconsciousness characteristic signal image process is brought to give rise to a signal, which calls for the person's attention.
