Abstract:
The invention relates to a method for measuring and indicating a true direction of a tracked object. The invention also relates to an apparatus and a tracking system utilizing the method. The invention also relates to a direction determination circuitry and to a computer readable storage medium comprising computer readable code, which is utilized in the direction determination circuitry. In the method a radio-bearing device shows all the time on a display true directions wherefrom a radio-bearing have been taken. The direction of the maximum signal strength measurement is highlighted on the display.
Abstract:
The memory indicia system allows to make a distinctive alignment range on an optical scope of a firearm. The system comprises a basic indicia indicator, which is to be attached to the alignment turret of an optical scope, and one or more additional indicia components to be attached on the basic indicia indicator. Both the basic indicia indicator and additional indicia component have at least a range value indicating the alignment distance, an alignment mark, and a cartridge code as indication of the type of cartridge used. The basic indicia indicator and the additional indicia component are film-like components the one side of which has a film adhesive covered by a removable protective film. The components are attached to the rim of the optical scope's alignment turret after the firearm has been aligned. The memory indicia system also comprises a separate cartridge item indicator to be attached to a cartridge box.
