Energy saving device (10) associated with a portable electronic apparatus (11), and comprising activation/de-activation means (17, 18) associated with said apparatus (11) and able to memorize a determinate reference position and/or functional condition ( f<SUB>a</SUB>; ?f<SUB>a</SUB>) of said apparatus (11), to detect an instantaneous position and/or functional condition (f<SUB>w</SUB>; ?<SUB>w</SUB>) of said apparatus (11) relative to the operator (12), to command the automatic activation of said apparatus (11) when said instantaneous position and/or functional condition (f<SUB>w</SUB>; ?<SUB>w</SUB>) substantially corresponds, with a desired margin of tolerance (?f; ?? ) to said ; reference position and/or functional condition (f<SUB>a</SUB>; ?<SUB>a</SUB>), and to command the automatic de-activation, even complete, of said apparatus (11) when said instantaneous position and/or functional condition (f<SUB>w</SUB>; ?<SUB>w</SUB>) is different, with a desired margin of tolerance (?f; ?? ), from said reference position ; and/or functional condition ( f<SUB>a</SUB>; ?<SUB>a</SUB>). |
