Title: A METHOD AND A DEVICE FOR CONTROLLING AND POWERING A SMOKE GENERATOR
Abstract:
A smoke generator and driver circuit (46) for controlling and powering a smoke generating canister (38), said driver circuit (46) comprising a power output connected to said smoke generating canister (38) for activation thereof. It comprises a charging unit (50) providing after a charging process sufficient power for igniting and driving said smoke generating canister (38), a switching unit (52) connected to said charging unit (50) and to a first pole (56) of said smoke generating canister (38) for releasing power from said charging unit (50) to said smoke generating canister (38), and a connecting unit (54) connected to a second pole (58) of said smoke generating canister (38) for allowing power to flow through said smoke generating canister (38), wherein activation of both said connecting unit (54) and said switching unit (52) during an overlapping time period is required for activation of said smoke generating canister (38). A method comprises applying a charging signal a charging input of the driver circuit (46), applying a control signal to a connect input of said driver circuit (46), and applying a trigger signal at a trigger input of switching unit (52).
