  • Publication number: 20090277451
    Abstract: A facial mask for filtering ambient air is formed from a pre-form of a multilayer flexible flat filter member with solid plastic side ribs of a size to extend the filter member over the mouth and nostrils of the user. The flat pre-form filter member can have a trapezoidal perimeter with an endless band of a hypoallergenic adhesive tape encircling a perimeter opening of the filter member and operable for sealing with the user's skin to prevent leakage over extended use. Portions of the adhesive tape can self-seal to form a structural base for maintaining a central concavity by cantilevering the side ribs to ensure a large filtration area offset from the nostrils and mouth of the user. The flexible filter material can further include an activated carbon layer.

  • Publication number: 20080110469
    Abstract: A facial mask for filtering ambient air is formed from a pre-form of a multilayer flexible flat filter member of a size to extend over the mouth and nostrils of the user. The flat pre-form filter member can have an ovoid perimeter with an endless band of a hypoallergenic adhesive tape encircling a perimeter of the filter member and operable for sealing with the user's skin to prevent leakage over extended use. Portions of the adhesive tape can self-seal during a sizing step to form structural paths for maintaining a central concavity to ensure a large filtration area offset from the nostrils and mouth of the user. The flexible filter material can further include an activated carbon layer.

  • Patent number: 6127940
    Abstract: An infra-red secure remote controller having a xenon gas discharge tube which is ignited and pulse modulated with a code impressed on the resultant xenon plasma arc. Each pulse modulated code represents a channel formed of a short pulse burst train of a plurality of high-energy optical pulses. The optical pulses are repeated about 10 to 15 times in a pulse burst train, so that the actual pulse burst train duration will comprise the pulses plus the dark interval time between pulses. Both the pulse length, the dark interval time, and the pulse burst train length are used by circuitry in a receiver for the controller to identify and distinguish an actual transmission from other interfering transmissions. The infra-red remote controller utilizes pulse burst length factors to enhance the reliability of the transmission and increase the possible number of separate codes available.

  • Patent number: 6042637
    Abstract: A miniature air purifier produces a corona discharge surrounding a needle-like emitter point connected to a negative DC power supply. The power supply operates from a nine volt battery and contains a step-up voltage inverter having a single transformer outputting high voltage spikes with a voltage multiplier operating on the output of the inverter. The production of high voltage spikes of about 200 Hz rather than a sinusoidally varying voltage significantly reduces current consumption. The needle-like emitter point is located about 1/4-inch from an 80% open mesh metallic grid held at ground potential. Corona discharge at the emitter point ionizes the air and creates ozone, and nitric oxide both of which combine with direct electron impact decomposition to detoxify and destroy a wide variety of airborne pollutants including pathogens, chemicals and allergens.

  • Patent number: 5484472
    Abstract: A small, battery-powered air purifier can be clipped to a wearer's front shirt pocket or worn suspended from a cord about the wearer's neck. The device includes a housing containing a compact circuit that transforms direct current provided by the battery into a negative high voltage pulsating current which is connected to a sharp metal point contained within a chamber inside the hollow housing. A corona discharge forms on the sharp point, ionizing air molecules and any particulates, and generating ozone. An opening into the chamber is covered by a noncorrosive metal grid connected to the positive terminal of the battery. The negative ions are attracted to this grid, thereby completing an electrical circuit. Movement of the ions to the grid results in mass movement of air which causes a stream of air to emerge through the grid. As the air passes the grid, negatively charged particulates are deposited on the grid.

  • Patent number: 5436531
    Abstract: A flash triggering system inductively coupled to a flash tube assembly's flash tube of a through-the-lens (TTL) strobe unit. The flash trigger monitors the electromagnetic field directly surrounding the strobe to which it is affixed using an electromagnetic inductive sensor. The photographic flash trigger is positioned by the mounting mechanism adjacent the flash tube so that the flash monitor detector is responsive to the excitation of a flash tube. The detector provides a detection signal indicative of whether or not the flash tube properly fired. A delay circuit delays any response for a predetermined time to allow for the main TTL flash cycle. Then, the activation circuit enables a separate transmitter to trigger the slave strobes while the camera shutter is still open.

  • Patent number: 5422543
    Abstract: A flash monitor alarm system is provided for detection of emergency vehicle flashers or for detection of flashes in photography. For emergency flasher detection the unit is positioned in a vehicle within a direct line of sight of potential emergency flashers. When emergency flashers are detected, an alarm is activated to warn the vehicle's occupants. For a photographic monitor alarm system, a detector is inductively coupled to a flash tube assembly's flash tube or tube power cable for activating a pulsating flash monitor indicator perceptible to the photographer when the flash tube has properly fired. The flash monitor alarm system includes flash monitor electronics and a power source, both of which are built into a compact housing.

  • Patent number: 4566085
    Abstract: A high intensity ultrasonic sound generator for producing bursts of ultrasonic frequency and a method of controlling vermin and pests by projecting such bursts into a space from which such vermin and pests are desired to be eradicated. The apparatus has a transformerless power supply employing a voltage divider with a low leakage input capacitor and an output capacitor having a significantly larger capacitance than that of the input capacitor, and wherein the load is voltage dependent so that the greater the charge on the output capacitor, the greater the load and, therefore, the output capacitor is prevented from excessively charging. Ultrasound frequency is generated by two astable multivibrators one of which duty cycles the other and means are provided to vary the frequency within each burst and the burst interval.

  • Patent number: 3956692
    Abstract: A radio frequency oscillator circuit has its tuning circuit coil mounted so as to conveniently receive an object to be tested in preselected precisely defined positions proximate to the windings thereof. A "standard" metal object is placed in a predetermined position proximate to the coil windings and the oscillator activated. The output of the oscillator is detected to produce a DC which is a function of the size, shape, specific gravity and metallic content of the piece being tested. This DC output is amplified and fed to a meter. A nulling circuit is utilized to "null" the meter circuit with the "standard" or reference object in position proximate to the oscillator coil. An object to be tested is then placed proximate to the coil in precisely the same position that was formerly occupied by the "standard" and the meter observed for deviations from the "null" position.
