Roller based accelerometer

Abstract

A roller-based accelerometer (100) is disclosed and includes an enclosure (1). A hub (2) is defined at a center of the enclosure (1), concentric to an inner surface (1a) of the enclosure (1). A bearing (3) is rotatably housed in the hub (2). An arm (4) is fixedly connected to the bearing (3). The arm (4) is configured displace within the enclosure (1). A plurality of sensors (6) is mounted on the enclosure (1). A roller (5) is positioned at a free end of the arm (4), contacting the inner surface (1a) of the enclosure (1). The roller (5) traverses the inner surface of the enclosure and over the plurality of sensors (6). The arm (4) angularly oscillates when the accelerometer (100) is accelerated and is dependent on the position of the roller (5) over one of the plurality of sensors (6) to indicate the acceleration of the accelerometer (100).

Dependencies are inferred from the claim text.
