A computer-implemented method includes: determining, by a computing device, a location of an individual in a building relative to the location of an exit of the building; determining, by the computing device, the location of obstacles or hazards within the building; determining, by the computing device, a path from the individual to the exit based on determining the location of the individual relative to the exit and the location of the obstacles or hazards; generating, by the computing device, signaling instructions based on the path; and outputting, by the computing device, the signaling instructions to one or more signaling devices, wherein the outputting the signaling instructions control operations of the one or more signaling devices to guide the individual to the exit based on the path.

The invention relates to a hydraulic rescue device (1) for manual operation by one rescuer. The rescue device (1) comprises a hydraulic cylinder (5) comprising a cylinder tube (6) and at least one piston rod (7, 7) that can be adjusted relative to the cylinder tube (6), at least one first support surface (17) formed on the cylinder tube (6) for supporting the rescue device (1) in a load-transferring manner on first object surfaces that can be freely selected by a rescuer, at least one second support surface (19) for supporting the rescue device (1) in a load bearing manner on second object surfaces that can be freely selected by a rescuer, and at least one manually operable control valve (14). At least one or more markings (23, 23) are provided on the casing surface (22, 22) of the at least one piston rod (7, 7), which at least one marking (23, 23) is provided at least to signal a remaining stroke (24) that is still available and/or an adjusting stroke (25) already travelled of the at least one piston rod (7, 7) relative to the cylinder tube (6).

An emergency escape tool for quick escape from a crashed automobile includes a body member defining an interior area. The walls of the body member define a slot and a blade is mounted therein, the blade being capable of severing a seatbelt of the automobile. The emergency escape tool includes a hammerhead portion coupled to the upper end of the body member and having a conical shape and a tip extending away from the upper end that is operable to break the glass window of the automobile. An immersion sensor is coupled to the body member and operable to detect immersion in water. The body member may be coupled to a seat of the automobile. A discharge member is associated with the body member and is operable to release the body member away from a mounting portion if immersion in water is detected.

A multifunction flashlight includes a flashlight body defining opposing front and rear ends, a light source with a LED light mounted in the front end of the flashlight body, a light source switch mounted on the flashlight body near the front end, a focus adjustment device mounted on the flashlight body between the light source and the light source switch, multiple tools pivotally connected to the rear end of the flashlight body and receivable inside the flashlight body, an emergency exit hammer pivotally connected to the rear end of the flashlight body and receivable inside the flashlight body, a release switch mounted on the flashlight body near the rear end, a seat belt cutter, and a USB jack for battery charging.

A multi-purpose tool and a method for use thereof, where the multi-purpose tool includes a first component having a first shaft and at least one first tool affixed thereto and a second component comprising a second shaft having at least one second tool affixed thereto, the second shaft being substantially hollow and capable of slidably receiving the first shaft. The multi-purpose tool further includes a quick-securing mechanism disposed along the length of the second shaft including a dial that is rotatable relative to the second shaft and having a threaded portion affixed to the dial.
