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.

Air purifier

An electrostatic precipitation air cleaner to reduce ozone output is provided. The electrostatic precipitation air cleaner includes a housing with an air inlet and outlet. Located in the housing are an air mover for moving a stream of air along an airflow path between the inlet and the outlet, an ion emitter electrode positioned in the airflow path downstream of the inlet for ionizing particulates entrained in the stream of air, a collector electrode having an inlet downstream of the ion emitter electrode, and an intermediate element intermediate the ion emitter electrode and the collector electrode. The collector electrode is comprised of a plurality of collector plates spaced apart in a direction transverse to the airflow path. The plates are electrically biased to create and maintain an electric field in the space therebetween to precipitate ionized particulates entrained in the stream of air onto a confronting surfaces of the plates.

A portable rechargeable personal ionic air purifier energizing a personal airspace and cleaning particulate pollutants therefrom in a manner that poses little or no personal shock risk and that minimizes battery drain to maximize battery life includes ionization means and ionization actuation means cooperative to provide ion bursts at regular intervals to energize and to clean particulates from the personal airspace. The ionization means includes an ion emitter and the ionization activation means includes means for providing a pulse train of predetermined frequency and duty cycle. The ion emitter may be removably mounted to a portable housing and/or to a facemask or other objects in the personal airspace via an elongated flexible cable.

A sound machine having a pseudo random white noise generator provides white noise sound therapy of selectable tone/texture, bandwidth and/or peak frequency to those suffering from tinnitus or others seeking noise-masking or sleep or relaxation. The sound machine having a pseudo random white noise generator includes a user input interface having a tone/texture user input control, a band pass user input control and a peak select user input control. The tone/texture user input control selects the tone/texture of the white noise sound generated, the bandpass user input control the bandpass of the white noise sound generated and the peak select user input control provides the ability to select frequency peaks of the white noise sound generated.

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.

Relaxation inducing sleep mask

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.

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.

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. It is mechanically stable and has high particulate collection efficiency because it's ionizer bars have a predetermined preferably air foil shape that provides improved ionization efficiency and that imparts improved torsion stability rendering it possible to provide taller electrostatic filter cartridges and/or greater cleaning power.
