Scent delivery device and method of simulating scent in a virtual environment

A scent delivery cartridge comprising:

• a scent reservoir having a basin, a lid and a scented material placed in the basin, wherein the lid has scent passages;
• a housing fixably connected to the scent reservoir and defining an enclosure with an opening;
• a valve fixably connected to the lid of the scent reservoir and variably covering a portion of the scent passages, wherein the valve is connected to a motor which is connected to a computer via a first motor controller, and wherein the position of the valve is controlled by a signal received from the computer;
• and
• a fan connected to the housing and positioned at least partially inside the housing such that, when operating, the fan directs air from within the housing to the outside of the housing, through the opening, wherein the fan is electrically connected to a motor and a speed control circuit, and the speed control circuit and the motor are each connected to a computer via a second motor controller, and wherein the rotational speed of the fan is controlled by a signal received from the computer.

A scent delivery system comprising:

• a base adapted for holding at least one or more scent cartridges;
• one or more scent cartridges detachably fixed to the base, each one or more scent cartridges having a scent reservoir and a valve, wherein the scent reservoir includes a basin, a scented material placed in the basin, and a lid containing scent passages, and wherein the valve is fixably connected to the lid of the scent reservoir and variably covers a portion of the scent passages;
• a communication board detachably fixed to the base, containing a controller and a microprocessor, wherein the microprocessor is capable of receiving input signals from a signal generator through an electronic connection, processing the input signals, and transmitting output signals through the controller to the valve for scent release;
• and
• a power supply detachably fixed to the base, providing power to the scent cartridges and the communication board.

A method of simulating a virtual reality environment, comprising:

• providing a visual and acoustic representation;
• providing a wearable scent delivery system comprising one or more scent cartridges, each cartridge containing a different scent;
• and
• releasing one or more scents from one or more cartridges in a pre-determined order for a pre-determined duration at a pre-determined intensity in synchronism with the visual and acoustic representation.
