  • Publication number: 20110128663
    Abstract: A connecting structure reduces noise effects on an electronic device when hot docking the electronic device to mitigate against malfunctions. When a first electronic device having a first EMI shield is docked with a second electronic device having a second EMI shield, an ESD contact portion, which is connected to the second EMI shield and has higher in impedance than an EMI connecting portion, comes in contact with the first EMI shield earlier than the EMI connecting portion. Electrostatic charge carried on the first EMI shield moves slowly to the second EMI shield due to the high impedance of the ESD contact portion.

  • Publication number: 20110116202
    Abstract: Aerodynamic effects are found when air flows over objects such as aircraft and motor cars moving through ambient air. The flow of air through the objects involves issues concerned with aerodynamics. Forced circulation of air through pipes presents numerous problems of aerodynamics because of the variable behavioural modes of operation generally in subsonic mode. Opposing forces then come into play and throttle the flows, thus reducing the effectiveness of a given diameter or cross section under particularly critical conditions in the flow of gases, generally air. The flow of gases or liquids close to the walls is slowed and opposes the overall flow, creating differential flow gradients between the centre of the flow and the peripheral edges thereof.

  • Patent number: 7822355
    Abstract: The present invention is related to preventing dust agglomeration on a sharp electrode which is used for generating corona. According to certain aspects, the invention includes a dust shroud which decreases or prevents dust accumulation on the sharp electrodes. The dust shroud changes the gas flow path so as to reduce the amount of gas passing near the sharp electrode. An advantage of the shroud is that it prevents dust from building up on the electrodes. The shroud is a simple, passive addition to the electrostatic pump, such that the pump is otherwise able to operate normally throughout its life. In embodiments, the shroud can be used to protect a corona electrode used in heat sink applications especially in electronics cooling. It can also be used in electrostatic precipitators for cleaning dust or chemical or microbe particles from air.

  • Patent number: 7821762
    Abstract: With a piezoelectric transformer formed of a ferroelectric element which generates a high voltage in a secondary section upon application of an AC voltage to a primary section, ground electrodes are attached to upper and lower surfaces of the secondary section of the piezoelectric transformer via a dielectric sheet for insulation in tight contact therewith such that a dielectric barrier discharge occurs around the ground electrodes to generate positive and negative ions, and an air flow is injected from an air nozzle to flow toward a neutralized subject across the ground electrodes.

  • Patent number: 7821765
    Abstract: A light to plug into a wall socket having a negative ion generator in the form of a pin. The pin design can be easily cleaned with a swab and cleaning solution such as rubbing alcohol, eliminating the need to trim or clean a brush electrode when corrosion or deposits form. The negative ion generator is always on and produces the negative ions to purify the air. The device can have a light sensor to activate the light when light is low. The device can also come with light emitting diodes which can be set to indicate the status of the various systems of the device. The device can come equipped with an air freshener that disperses vaporized perfume into the air.

  • Patent number: 7796370
    Abstract: A lightning protection device is provided. The device includes a lower field coupler, an upper field coupler, a lightning sensor, and a controller. The lightning sensor includes a differential voltage window comparator. The lower field coupler is capacitively coupled to the earth ground, and the upper field coupler is coupled to the local atmospheric electric field. If a ground potential rise (GPR) event occurs, the differential voltage window comparator trips. If the differential voltage window comparator trips or if a power line transient occurs, the controller disconnects the power phase, neutral, and ground wires to isolate sensitive equipment. In some embodiments, the controller also detects power line transients and disconnects the power, phase, neutral, and ground wires if a power line transient is detected.

    Abstract: Methods and apparatus (40) to neutralize the charge on a moving web (42) by splitting the field present on the web (42). One portion of the field is removed by a grounded element (55a, 55) proximate to, and optionally contacting, one side of the web (42). Proximate the opposite side of the web, the apparatus includes an ion source (57a, 57b, 57c), which provides ions to the web (42) to neutralize the charge remaining on the web (42), and a second grounded element (50a, 50b, 50c) positioned between the ion source (57a, 57b,57c) and the web (42). The methods provide a web (42) that is net neutralized and is also dual-side or bipolar neutralized.

  • Patent number: 7751170
    Abstract: Charge transfer is provided to or from an electrically isolated test body by AC modulation of the photoelectric effect. More specifically, a reference body is disposed near the test body without physical contact between the reference and test bodies. Facing surfaces of the reference and test bodies are illuminated by optical radiation having a sufficiently short wavelength that charged particles are emitted from the reference and test bodies. An electrical bias is established between the reference body and the test body. Both the optical radiation and the electrical bias are modulated at the same frequency. A magnitude and direction of a charge transfer rate between the reference and test bodies is set by selecting a phase relation between the optical radiation and the electrical bias.

  • Publication number: 20100139743
    Abstract: Systems and methods are disclosed for removing charge buildup/leakage from solar modules. A discharge controller may be coupled between a solar module and a string bus of a solar array. The discharge controller may be configured to disconnect the solar module from the string bus, and to connect a grounded frame to solar cells of the solar module. Since the grounded frame of the solar module may be grounded, connecting the grounded frame and the solar cells allows charge buildup/leakage to discharge into ground.
