1. A protection device to protect an electronic apparatus, the protection device comprising:
- a motion-detection device, to supply at least one alert signal in response to conditions of motion of the protection device;
a counter;
a first logic circuit, to increment the counter in a presence of a first value of the alert signal, in a first operating condition; and
a second logic circuit, to generate a protection signal on a basis of a count value of the counter;
wherein the first logic circuit is configured to decrement the counter in a presence of a second value of the alert signal, in the first operating condition.

Abstract
A device for protecting an electronic apparatus includes: a motion-detection device, for supplying at least one alert signal in response to conditions of motion of the protection device; a counter; a first logic circuit, for incrementing the counter in the presence of a first value of the alert signal, in a first operating condition; and a second logic circuit, for generating a protection signal on the basis of a count value of the counter. In addition, the first logic circuit is configured for decrementing the counter in the presence of a second value of the alert signal, in the first operating condition.

12. An electronic apparatus, comprising:
-
a microprocessor; a peripheral unit controlled by the microprocessor; and a safety device coupled to the microprocessor to supply a protection signal, the safety device including; a motion-detection device to supply at least one alert signal in response to a condition of motion; a counter coupled to said motion-detection device; a first logic circuit coupled to said counter, to increment the counter in response to a first value of the alert signal, in a first operating condition; and a second logic circuit coupled to said counter, to generate said protection signal based on a count value of the counter; wherein the first logic circuit is configured to decrement the counter in response to a second value of the alert signal, in the first operating condition. - View Dependent Claims (13, 14, 15)

16. A method for protecting an electronic apparatus, the method comprising:
-
detecting conditions of motion of the electronic apparatus; incrementing an index in a presence of the conditions of motion, in a first operating condition; generating a protection signal on a basis of the index; and decrementing the index in an absence of the conditions of motion, in the first operating condition. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An electronic apparatus, comprising:
-
means for detecting a condition of motion; means for changing an index to increment said index in response to detected presence of said condition of motion, in a first operating condition; and means for generating a protection signal based on a value of the index, wherein said means for changing decrements the index in response detected absence of said condition of motion, in the first operating condition. - View Dependent Claims (28, 29, 30)
