Abstract: A mouth guard comprises a base member configured to fit inside the mouth of a user, and at least one shock-sensing and indicating device coupled to the base member. In one exemplary embodiment, the shock-sensing and indicating device is a passive shock-sensing and indicating device that detects a shock substantially along a selected axis with respect to the base member. In another exemplary embodiment, the at least one shock-sensing and indicating device detects a shock substantially along a plurality of selected axes with respect to the base member, each selected axis being substantially orthogonal from another selected axis. The shock-sensing and indicating devices can be configured to detect different levels of shock. In one exemplary embodiment, the shock-sensing and indicating device comprises a multi-component chemical-reaction system, such as a chemi-luminescent reaction system.

Abstract: A system and a method for a controllable power-assisted application of pressure includes a force sensor capable of sensing a user-applied force; and a force generator responsive to the sensed user-applied force and capable of generating a force that is applied to a pressure-applying device. A force magnitude of the force applied to the pressure-applying device is based on a magnitude of the sensed user-applied force. One embodiment provides that the force applied to the pressure-applying device by the force generator exerts a predetermined amount of pressure against a surface. Another embodiment provides that the force magnitude is greater than a magnitude of the sensed user-applied force. Yet another embodiment provides that the force magnitude is proportional to a magnitude of the sensed user-applied force.
