  • Publication number: 20150245751
    Abstract: A liquid extraction cleaning device comprises a vacuum pump, a liquid pump, a cleaning solution tank, a recovery tank, first and second spray nozzles, a spray selection switch, a vacuum inlet port, an agitator assembly, and a handle. The spray selection switch controls whether liquid is expelled from the second spray nozzle when liquid is expelled from the first spray nozzle. The agitator assembly comprises first and second agitators. The first agitator is configured to rotate. The second agitator is configured to reciprocate. The handle is pivotally connected to the rest of the liquid extraction cleaning device and is lockable in several pivotal orientations. The handle can also be pivoted forward from a rearwardly extending direction to an extent that it extends forward horizontally.

  • Publication number: 20140035114
    Abstract: In one embodiment, a semiconductor package structure includes a substrate having a well region extending from a major surface. An interposer structure is attached to the substrate within the well region. The interposer structure has a major surface that is substantially co-planar with the major surface of the substrate. An electrical device is directly attached to the substrate and the interposer structure. The interposer structure can be an active device, such as a gate driver integrated circuit, or passive device structure, such as an impedance matching network.

  • Publication number: 20130314659
    Abstract: A liquid crystal panel includes a first substrate, a second substrate, a sealant layer, and a liquid crystal layer. The second substrate is disposed opposite to the first substrate. The sealant layer is disposed between the first substrate and the second substrate for combining the first substrate and the second substrate. A plurality of openings is defined by the first substrate, the second substrate, and the sealant layer. The liquid crystal layer is disposed between the first substrate and the second substrate. The openings are configured to inject a liquid crystal material into space between the first substrate and the second substrate to form the liquid crystal layer by capillarity.

  • Patent number: 7873367
    Abstract: Methods and systems are provided for determining the location of a first wireless device (e.g., a mobile unit) within a wireless network comprising a plurality of second wireless devices (e.g., access points). The method includes identifying an overlap area corresponding to the intersection of RF ranges for the one or more second wireless devices then computing a set of signal strength values, each associated with a measure of RF signal strength (e.g., RSSI) received by the plurality of second wireless devices from the first wireless device. A decision metric is evaluated for a plurality of locations within the overlap area based on the set of signal strength values. The location of the first wireless device is determined by selecting, from the plurality of locations, a location having the optimum value of the decision metric within the overlap area. The decision metric may utilize a minimum mean square error (MMSE) calculation.

  • Patent number: 7826862
    Abstract: Methods and systems are provided for determining the location of a first wireless device (e.g., a mobile unit) within a wireless network comprising a second wireless device (e.g., an access point). The method includes determining a signal strength contour associated with RF communication between the access point and the mobile unit, and adding a correction factor to the signal strength contour to produce a corrected signal strength contour, wherein the correction factor includes the sums of the differences between the transmit power and the antenna gain associated with the mobile unit and the access point. In an alternate scheme involving stored fingerprint data, a correction factor is introduced based on the differences between antenna gains and transmit power associated with the mobile unit under consideration and the mobile unit used for generating the fingerprint data. The systems and methods disclosed herein are applicable, for example, to networks operating in accordance with 802.
