  • Patent number: 8151385
    Abstract: A shower curtain and support system employs an elongated rail supported at the shower or tub. The rail extrusion can be an extrusion with an inverted U profile, with an open slot or slots at its base. There are glides, e.g., nylon members with a ball, hemisphere, or other wide head portion and shaft that projects out through the slot from the open interior of the rail. The glides have one or two hook structures for attaching to a fabric curtain and a vinyl curtain liner. In one preferred version, there is a liner hook and spring retaining arm on one side that fits into the grommet at the top of the liner. On the other side is a short arm with a button that fits into a button hole on the cloth or fabric curtain. The curtain has blind button holes or grommets at its upper hem, so that the hook structure, e.g., button, does not show.

  • Patent number: 8149227
    Abstract: Systems for removing or attenuating friction and/or click noise generated during writing with a smart pen are disclosed. In a smart pen, the writing cartridge is biased towards a first side of the smart pen internal cavity by a low-force biasing system without affecting writing cartridge movement. For example, the writing cartridge is comprised of a magnetic material and a magnet is embedded into the first side of the smart pen internal cavity to bias the writing cartridge towards the first side. Alternatively, the material comprising the writing cartridge or smart pen internal cavity is modified, reducing friction between the components. As another alternative, a DSP method identifies analyzes one or more parameters of received audio data to differentiate click noise from audio data, and may receive data from a movement sensor indicating when the writing cartridge has moved to reduce power consumption for identifying click noise.

  • Patent number: 8109448
    Abstract: A system and method for combining an additive with a carrier fluid in a spray nozzle. The carrier fluid is fed to one or more nozzles that include an embedded Venturi. The Venturi includes an induction port connected to an additive supply. As the carrier fluid flows through the nozzle, the flow creates a vacuum or suction force that draws in the additive. Of particular advantage, the concentration of the additive combined with the carrier fluid can be maintained constant even if the flow rate of the carrier fluid varies. The system and process are particularly well suited for spraying fields, such as crop fields or orchards, with an agrochemical.
