A light bulb (10) includes a translucent housing (12) and a base (24). The housing (12) includes a plurality of LEDs (14a, 14b, 14c, and 15) positioned so as to emit light through the housing (12). The base (24) is configured to mate with a light socket. The base (24) also includes a compartment (23) for receiving and securing a replaceable active ingredient cartridge (22), and an active ingredient dispenser (20) for emitting an active ingredient from the cartridge (22) when the cartridge (22) is secured in the compartment (23). A fluorescent light source (30) may also be provided in the housing (12) as a source of illumination.

LED light bulb with active ingredient emission

A novel apparatus for producing combined presentation of light and aroma to produce a desired overall sensory effect. The includes a fragrance dispenser (31), a light source (42), an audio system (52), and a microprocessor (99). The fragrance dispenser (31) is refillable and controllable, so as to adjust the rate at which the fragrance dispenser dispenses a fragrance. The light source (42) comprises a plurality of LEDs (40a-40c) of at least two different colors and is controllable so as to adjust the operation of the plurality of LEDs (40a-40c). The audio system (52) controls sounds to be emitted from the apparatus. The microprocessor (99) controls the rate at which the fragrance dispenser (31) dispenses fragrance and the operation of the light source (42) and audio system (52).

Coordinated emission of fragrance, light, and sound

An oubdoor light system (75) comprising a plurality of light elements (.10) linked. to a central controller (23). Each light element include a translucent shell (11) and' a plurality of LEDs (15,16,17) positioned so as to emit a light show through the shell (11). A compartment for receiving a replaceable volatile active cartridge (27) and.a heater (24) ' for, enabling the device to. emit an active ingredient from the cartridge (27). A white light source (18,18a) may be provided in each device along with the LEDs (15,16,17). The devices can be used as white light sources,. for displaying a coordinated colored light shows, for displaying colored light schemes and for volatile active emission. The devices of the disclosed system may include an acoustic transducer (33), a light sensor (25a), a motion detector (25a) and/or a acoustic receiver (26a) thereby enabling light and sound shows to be dependent upon ambient light intensity, motion detection and/or ambient noise. The system is suitable for outdoor home lighting, porch and deck lighting and path/driveway lighting.

Color changing outdoor lights with active ingredient and sound emission

A light element includes a translucent shell and a base. The base supports a plurality of LEDs positioned so as to emit a light show through the shell. The device also includes a compartment for receiving and securing a replaceable volatile active cartridge and a heater for enabling the device to effectively emit an active ingredient from the cartridge when the cartridge is secured in the compartment. A white light source is provided in the shell as a source of illumination along with the LEDs. The device can be used as a white light source, for displaying a colored light show, for displaying colored light schemes and for volatile active emission. The device may include an acoustic transducer for producing light and sound shows. The device may also include a light sensor, a motion detector and/or a microphone or acoustic receiver thereby enabling the light and sound show to be dependent upon ambient light intensity, motion detection and/or ambient noise.

Color-changing light devices with active ingredient and sound emission for mood enhancement

A powering subassembly for a portable electronic device includes a main battery, a converter, a backup battery, and a controller. The main battery provides a main voltage and the backup battery can provide a backup voltage. The converter receives the main voltage and increases the main voltage to at least one operating voltage. The controller receives the operating voltage from the converter, monitors the voltage of the main battery, and compares the monitored main battery voltage to a main battery low voltage threshold. The controller transmits a disconnect signal to decouple the main battery from the converter if the monitored voltage from the main battery is less than the main battery low voltage threshold. The controller transmits a connection signal to couple the backup battery to the converter if the monitored voltage is less than the main battery low voltage threshold. The backup battery provides the power for a predetermined minimum amount of time.

Method and apparatus for predicting end of battery life

An air freshener dispenser is taught having plug-through capability as well as a night light. The dispenser is a plug-in diffuser for such active materials as fragrances and air fresheners, and eliminates the consumer problem of loss of an electrical outlet, by providing a receptacle into which another plug may be inserted. The dispenser uses replaceable cartridges of material to be dispensed, and provides a night light for those who desire such.
