  • Patent number: 6911186
    Abstract: An electro-kinetic air conditioner for removing particulates from the air creates an airflow using no moving parts. The airflow is subjected to UV radiation from a germicidal lamp within the device. The conditioner includes an ion generator that has an electrode assembly including a first array of emitter electrodes, a second array of collector electrodes, and a high voltage generator. The device can also include a third or leading or focus electrode located upstream of the first array of emitter electrodes, and/or a trailing electrode located downstream of the second array of collector electrodes, and/or an interstitial electrode located between collector electrodes, and/or an enhanced emitter electrode with an enhanced length in order to increase emissivity.

  • Patent number: 6902070
    Abstract: A high capacity motorized rack holds a plurality of jewel case enclosed CDs in holders flexibly inter-connectable with each other to form a rotatable continuous loop. The loop is rotatably retained within a vertical rack housing and is driven by a motor, disposed within the housing, under user control such that the loop is rotated until a desired CD is moved to the top region of the belt. A rack may hold two or more such loops of inter-connected holders. In one embodiment a holder retains a single jewel case, and comprises two independent loops that are rotated with a single motor. A preferred embodiment employs inter-connectable holders that each retain two jewel cases in a side-by-side configuration. A lamp and/or barcode scanner may be disposed on the housing for ease of CD selection. The housing base preferably is detached during shipping to permit transporting the rack in a smaller volume container. User control can include voice commands to direct loop rotation and speed.

  • Patent number: 6647988
    Abstract: A nail care system which contains a portable case, drying compartments and drying compartment covers. The drying compartments are vertically oriented on opposite sides of the portable case. The drying compartment covers are pivotally mounted to the portable case and open and close like a gull-wing type door. The vertically oriented drying compartments allow the user to place their hands in a comfortable, vertical position in front of them during the drying process. The vertical orientation also reduces the footprint of the portable case. Further, the nail care device may be adapted to dry toenails.
