Device with opening detection

Abstract

Disclosed is a device comprising a housing that comprises components; a cover configured to be positioned on the housing to restrict access to the components when the cover is in the closed position; a capacitor and a fuse, the capacitor and fuse being dimensioned so that the fuse blows when the capacitor discharges through the fuse; a capacitor charging circuit configured to charge the capacitor when the device is powered up; a discharge circuit for discharging the capacitor through the fuse, said discharge circuit comprising a first switch cooperating with a part integral with the cover in order to prevent the discharging of the capacitor when the cover is in the closed position; and to allow the capacitor to discharge through the fuse when the cover is in the open position.

Dependencies are inferred from the claim text.
