  • Publication number: 20030209420
    Abstract: An air-transporter conditioner device includes a housing defining an inlet and an outlet. An electro-kinetic system is disposed in the housing to create an airflow moving from the inlet to the outlet. A timer measures a time period corresponding to the electro-kinetic system and causes an indicator light to illuminate when the measured period reaches a threshold. An arc sensing circuit detects arcing between the first and second electrode arrays of the electro-kinetic system. The electro-kinetic system is turned off in response to arcing being detected by the arc sensing circuit. An indicator light can also specify that arcing has been detected.

  • Publication number: 20030206840
    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: 6615770
    Abstract: An electronic device detects the presence of an animal such as a pet in a protected area and outputs a deterrent signal that preferably includes the voice of the pet's owner admonishing the animal. The animal is detected by sensing at least one of sound, heat, vibration, and motion. The deterrent signal may include loud noises, and signals audible to the animal but not to humans. The deterrent signal may also include bursts of light. The device can vary the nature and quality of the deterrent signal if the animal remains near the protected area for a predetermined time.

  • Patent number: 6604022
    Abstract: A robot which incorporates a body, arms with a hand grip, legs, several sensors, light elements, an audio system, and a video system. The sensors allows the robot to interact with objects in the room, and prevents the robot from traveling off an edge or bumping into obstacles. The light elements allow the robot to express moods. The audio system allows the robot to detect and transmit sounds. The video system allows a user to remotely view the area in front of the robot. Additionally, the robot may operate in a plurality of modes, including modes that allow the robot to operate autonomously. The robot may operate autonomously in an automatic mode, a security mode, a greet mode, and a monitor mode. Further, the robot is manipulated remotely.

  • Patent number: 6581797
    Abstract: A programmable vitamin and pill dispenser that is capable of storing multiple pill groups. The dispenser provides reminders to an individual when it is time to ingest the next serving. The serving is dispensed into a cup upon depressing a dispenser button. By loading the individual compartments specific to each serving, an individual does not have to create the serving each time.
