Abstract
A signaling system comprises a portable signaling unit, a remote alarm switch device, a central dispatch station, and a wireless communication system such as a cellular or telephone system, etc., and a GPS or alike system. The portable signaling unit and the remote alarm switch may be adapted to be worn at different locations on the person's body. The remote alarm switch may be concealed in the form of a wristband or in the form of any other object such as a broach, pendant, or keychain. When the person in distress activates the remote alarm switch or when the remote alarm switch is removed from the individual by a forceful or unauthorized action or when the signaling unit is removed from the proximity of the remote alarm switch, the portable signaling unit sends a data transmission which includes its location to the central dispatch station. The portable signaling unit also has manual alarm trigger capabilities so it can be used without the remote alarm switch unit. The central dispatch station receives the data transmission and accurately displays the user identification, stored personal information, nature of the alarm; in addition the location of the portable signaling unit is superimposed on a digitized map at a position corresponding to the location of the person wearing the portable signaling unit. The portable signaling unit can be remotely activated from a central dispatch station to determine and monitor the location of the portable signaling unit.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
