Acceleration sensor
First Claim
1. An acceleration sensor arrangement, an acceleration sensor comprising a first body portion, a second body portion, an interconnecting element making the first body portion integral with the second body portion and detecting means arranged for giving an indication when the second body portion damages the detecting means, characterized in that the acceleration sensor arrangement comprises a group of at least two said acceleration sensors arranged on one carrier, at least two of the sensors responding to different forces:

Abstract
A low-cost breakable inertial threshold sensor using mainly micro-machining silicon technology constructed on a silicon-wafer or on some other brittle material according to the MEMS process. The sensor comprises a first body portion, a second body portion, and detecting means for giving an indication if the second body portion has damaged the detecting means. The status of the sensor can be read in various ways. In one embodiment the status is remotely readable.

- 22. A handheld terminal, characterized by an acceleration sensor arrangement comprising a group of at least two acceleration sensors, at least two of the sensors responding to different forces, an acceleration sensor comprising a first body portion, a second body portion, an interconnecting element making the first body integral with the second body, and detecting means arranged for giving an indication when the second portion damages the detecting means and further giving an indication to the terminal user of the event.
- 24. A method in an acceleration sensor arrangement comprising a group of at least two acceleration sensors, an acceleration sensor comprising a first body portion, at least one second body portion and an interconnecting element making the first body portion integral with the at least one second body portion, the method comprising giving an indication when a second body portion of at least one acceleration sensor of the arrangement damages at least one detecting means.
