Abstract
A combination smoke detection device and laser escape indicator provides a primary circuit that electrically connects a power source to a laser. The primary circuit has a smoke detector switch that is operably controlled by a smoke detecting means. When the smoke detecting means detects smoke, it closes the smoke detector switch, thereby activating the laser to produce a laser beam. The laser is mounted on a swivel arm that is pivotally connected to a primary housing, the primary housing being rotatably attached to a base housing. The swivel arm and the primary housing together can be adjusted so that the laser projects the laser beam in a desired direction. When the combination is installed in a structure, the laser is manipulated so that when the laser generates a laser beam, the laser beam directs people to an exit from the structure. The primary circuit is preferably also connected to a siren, so when the laser is triggered, an audible siren is also activated, providing people within the structure with a warning of the fire.

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.
