<p>The cushion device mainly contains a flat body member containing a pad on top of a base. The base has an indentation on a top side for accommodating a pressure activation member. The pressure activation member contains a first disc resiliently supported on a top side of a second disc by a number of resilient elements. A number of sensitive switches are also provided on the top side of the second disc. The switches turn on a timing element by the descent first disc and then turn the timing element off when the first disc is restored to its original position by the resilient elements. A number of reminding elements such as a vibrator, a sound generator, and a light generator are connected to and commanded by the timing element to produce vibrations, sounds or voices, or lighting after a preset period of time.</p> |
