Personal safety device
First Claim
1. A personal safety system including a personal safety device including at least one housing containing a quantity of a marking substance that includes a unique chemical identifier that contains synthetic DNA, a propellant, a triggering apparatus including an initiator which is operative to activate the propellant to propel the marking substance from the housing to mark the area surrounding the device, and transceiver operable to transmit an RF distress signal that is of a unique frequency or character, so that the actual device transmitting the signal may be identified, the system further including a remote receiver to receive the transmitted distress signal, and a remote transmitter for transmitting an actuating signal to the personal safety device, the transceiver receiving the remotely transmitted actuating signal and transmitting the distress signal in response.

3. A personal safety device including at least one housing containing a quantity of a marking substance, an explosive charge, and a triggering apparatus including an ignitor which is operative to detonate the explosive charge to propel the marking substance from the housing to mark the area surrounding the device wherein the ignitor is actuated by moving one component relative to another component, to produce spark ignition by friction;
- wherein the housing includes a first housing part and a second relatively moveable housing part, movement of the second housing part relative to the first housing part to operate the triggering device; and
wherein the triggering device includes a cord attached to one or other of the triggering apparatus'"'"'relatively moveable components, the one component being moved relative to the other by a user moving the second housing part away from the first housing part to pull on the cord. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
