Emergency information management system
Issued: February 26, 2008
A wide-area emergency information management system includes a broadcasting entity (10) and delivers content to authorized receiver clients (20), such as PC’s, laptops, wireless devices, etc. The specific content (26), which can include voice, text, video or any other information content related to a planned response to a given crisis or emergency such as enemy attack or natural disaster, is prepared in advance (28), tailored to the class of recipient receiver client and/or user (44), securely downloaded (32,36) and stored locally in a secure cache (21). In response to a small control file from a centralized emergency management authority, the receiver client system accesses the cache (21), decrypts the content (26), and delivers it to the end-user.

United States Patent: 5784742, Giuliani, et al.

Toothbrush with adaptive load sensor
Issued: July 28, 1998
An electric toothbrush (10) with an adaptive load sensor (12) is disclosed. The toothbrush of this invention includes a brush head (16) that is vibrated by a drive assembly (18). The load sensor monitors the current drawn by the drive assembly to determine the mechanical load to which the toothbrush is exposed. The load sensor assembly produces an adaptive threshold signal that represents the instantaneous maximum pressure load. If the sensed load voltage exceeds the adaptive threshold signal, the load sensor assembly de-energizes the drive assembly and generatesan alarm signal so as to give the user a warning that the toothbrush has been excessively loaded.

Pacing toothbrush
Issued: August 13, 1996
A vibrating toothbrush, which includes a handle member, an elongated arm which has a brush head at the distal end thereof, and a drive assembly for moving the brush head at a selected velocity. Responsive to an on/off switch on the toothbrush is an on/off variable, which enables a master clock to produce a drive signal, the on/off variable being reset by a 120-second timer. A quadtimer variable, when in the enabled state, is responsive to the on/off switch to produce an audible signal and a difference in brush velocity at 30-second intervals within the 120-second period.
