Patent Images
1. Headwear comprising a covering for enclosing at least a portion of the head of a user, said covering including:
- a plurality of sensing devices, including at least one first sensing device constructed and arranged to detect a linear force and at least one second sensing device constructed and arranged to detect a rotational force, said plurality of sensing devices each being constructed and arranged to generate a signal in response to a sensed acceleration greater than a threshold acceleration; and
a signalling device connected to said plurality of sensing devices and being constructed and arranged to generate a perceivable signal in response to a signal received from either one of said plurality of signalling devices.

Abstract
A signalling device is installed in headwear, such as an athletic helmet, and includes sensing devices for detecting linearly and rotationally directed impacts above a selected magnitude. The sensing devices trigger the signalling device so as to produce a perceivable signal, thereby alerting observers that a potentially injurious impact has occurred.
