Problems solved by technology

[0007] Another problem affecting the performance of prior art devices is that false triggers are issued due to high and low frequency environmental conditions that should be ignored, but instead are interpreted as being detected as movement in the room

Embodiment Construction

[0020] figure 2 A room 20 is shown, which includes a fluorescent light source 22 and a window 24 through which sunlight enters the room 20. The device 26 is placed in the room 20, which is image 3 Shown more specifically in. The device 26 is suitable for dispensing the contents of the aerosol container 28 and is preferably one of the devices described in U.S. Patent Application No. 11 / 725,402 by Carpenter et al., which is fully incorporated herein by reference. The device 26 includes a housing 30 which is adapted to contain an aerosol container 28 and a battery 32. The device 26 also includes a sensor, such as a phototransistor 34, which detects changes in ambient light conditions in its sensing path. In this embodiment, the detected changes in the ambient light level, for example from a person 36 entering the room 20 and crossing the sensing path of the phototransistor 34, represent movement near the device 26 and cause the phototransistor 34 to produce A signal to initiat...

Abstract

The present invention relates to a dispensing device including a dispenser configured to dispense a volatile material, a sensor configured to detect an environmental condition, and a nonlinear circuit element coupled to the sensor to establish a bias point. A voltage level at the bias point varies nonlinearly with respect to a current that flows through the sensor, wherein the current that flows through the sensor represents the environmental condition. The dispensing device further includes a controller coupled to the bias point. The controller controls the dispenser to dispense the volatile material in response to the environmental condition.

Description

Technical field [0001] The present invention generally relates to a sensor device, and more specifically, to a device that dispenses volatile substances in response to detection of environmental conditions. Background technique [0002] Diffusion device or dispenser, used to distribute volatile substances, such as perfume, deodorant, insecticide, insect repellent, etc. Many of these devices are passive diffusion devices that distribute volatile substances only when the surrounding air is circulating, while others are active diffusion devices. Active diffusion devices come in various forms, some include fans and / or heaters that help volatile substances diffuse, others drive the valve stems of aerosol containers to distribute the volatile substances contained in them, and some use ultrasonic sensors to Break down liquid volatile substances into droplets and eject them from the device. There are also combinations that include any of the above or any other known types of active diff...
