Abstract: An eye mask for use to wake up and/or to go to sleep provides ease of cleaning or replacement without damaging electrical or optical components; different user selectable sunrise and sunset illumination modes respectively having blue-shifted and red-shifted spectra simulating natural sunrises and sunsets to assimilate the sleep/wake cycle to the natural rhythms of day and night; sunset and/or sunrise illumination modes that oscillate with fixed period or sequentially changing periods that correspond to brainwave frequencies that respectively facilitate going to sleep and/or waking and synergistically co-operate with corresponding sunset or sunrise light fields to help the user to fall into restful sleep or to awake refreshed and alert; and audio tone programming of illumination mode and treatment time and/or duration of therapy by a remote tone control generator.

Abstract: A relaxation inducing sleep mask includes a comfortable eye mask and a sleep module carried by the eye mask providing audible and/or visible patterns each intended to promote relaxation and to induce sleep.

Abstract: A high cleaning efficiency room air cleaner with a slim profile providing a clean air delivery rate sufficient to clean any ordinary size room includes a flat-panel housing having an internal chamber sized to receive conventional large area flat-panel furnace filters of standard size and a fan array preferably of high efficiency, low power axial computer fans mounted to the flat-panel housing. The room air cleaner may include a scent cartridge and a UV lamp assembly.

Abstract: A hairbrush includes a control panel, an interior vibratory element for providing massage therapy and a plurality of LEDs carried by the brush head for providing light therapy at a preselected wavelength selected to be of benefit to the hair and/or scalp. In response to user control input mode selection, the light and massage multi-therapy hairbrush selectively provides phototherapy, massage therapy, and combined massage and phototherapies.

Abstract: The disclosed electrostatic precipitator cartridge for a tower air cleaner in accord with the present invention is low-cost, because it is constructed of injected molded plastics material and stamped and extruded metal components. It is easy to clean, not only because it's constitutive metal parts and plastic components are machine washable but also because the cartridge as a whole is machine washable, the pieces and components are designed and arranged to prevent intracartridge fluid buildup or retention after washing, thereby eliminating any electrical shorting or arcing or other undesirable phenomena resulting therefrom that could interfere with the operation of the electrostatic filter cartridge.

Abstract: In one embodiment, an improved-customizability digital sound relaxation system having a sound card receiving port and a collectable sound card are cooperative to play prerecorded natural or other sounds by depressing one of a plurality of sound selector switches and a sound card selector switch. The new sounds of each collectable sound card customize the library of available sounds to individual taste. In another embodiment, an improved-flexibility digital sound relaxation system having at least two (2) prerecorded sounds stored at first and second memory locations of internal or external/internal memory devices may be selected and combined for concurrent and/or individual replay by depressing one of a plurality of sound selector switches and a combine switch, or by depressing one of a plurality of sound selector switches, a sound card selector switch and a combine switch.

Abstract: The sound pillow is sanitary and does not need to be discarded and replaced if it becomes soiled from use or accident, because it is constructed to be machine washable, and, among other things, it privately delivers good quality stereo audio for rest, learning, enjoyment or other purposes while being as easy and convenient to use as conventional bed pillows of standard size. The sanitary and easy to use sound pillow includes a speaker receiving pocket nested inside and open to a pillow casing and stereo speakers removably insertable into the speaker receiving pocket.

Abstract: An air cleaner is described wherein an ion wind is generated by an ionizing element and directed to pass over a dust collector surface. By proper design and adjustment of the ionizing element and collector, the unit can be operated without emitting charged particles, if any, in other than the direction of orientation of the dust collector surface and thus avoiding smudging of the surrounding walls. The collector may be cylindrical in form and may be separately detachable, rendering it readily available for cleaning.

Abstract: A portable, refillable water dispenser serving batches of water purified of organic and inorganic pollutants includes a portable, refillable and hand-holdable vessel for holding and pouring water having a spout and, inside the portable, refillable and hand-holdable vessel, moving water and still water processing module cooperative to remove inorganic and organic pollutants from water received batchwise by the vessel.

Abstract: A filter cartridge for a standalone point of use water purification device includes tandem first and second flow passageways containing flowthrough filter media that cooperate to provide opposing flow directions in the first and second flow passageways that reduce, if not eliminate, channeling, and provide self-wetting of the flowthrough filter media contained in the tandem first and second flow passageways, eliminating the need for post-use wetting steps.

Abstract: A duster cleaning member derives its suction power from a vacuum cleaner to which it is operatively coupled. A duster made of any material received thereby is cleaned by the filtration system of the vacuum cleaner which captures the dust and exhausts cleaned air back into the home or office environment.

Abstract: A multi-station RF thermometer and alarm system measures temperatures and/or percent relative humidity at remote locations by RF weather stations, and displays received temperature and/or other weather data telemetry on a multi-station base station that provides out-of-bounds alarm signal indications whenever temperatures are outside of user-selectable minimum and maximum values. Randomized transmission times in one embodiment and two-phase unique transmission schedules in another lessen the possibility of on-going collisions between two or more transmitters contending for the base station at the same time. Redundant data transmission lessens the possibility of environmental noise interference.
