  • Publication number: 20210195067
    Abstract: An example system includes an imaging device and an enclosure substantially separating the imaging device from an outside environment. The enclosure includes an air intake to force air into the enclosure and an aperture to allow air to escape the enclosure. The air intake and the aperture maintain an air pressure level in the enclosure greater than an air pressure of the outside environment.

    Abstract: The invention relates to a novel pharmaceutical sustained release formulation of guaifenesin. The formulation may comprise a hydrophilic polymer, preferably a hydroxypropyl methylcellulose, and a water-insoluble polymer, preferably an acrylic resin, in a ratio range of about one-to-one (1:1) to about nine-to-one (9:1), more preferably a range of about three-to-two (3:2) to about six-to-one (6:1), and most preferably in a range of about two-to-one (2:1) to about four-to-one (4:1) by weight. This formulation capable of providing therapeutically effective bioavailability of guaifenesin for at least twelve hours after dosing in a human subject. The invention also relates to a modified release product which has two portions: a first portion having an immediate release formulation of guaifenesin and a second portion having a sustained release formulation of guaifenesin.

  • Patent number: 9487934
    Abstract: A hydrant drainage boot is installed around a water supply line and a frost-free hydrant to prevent dirt and debris from blocking the drainage port, and ensures unobstructed drainage of the hydrant. The frost-free hydrant has a linear riser pipe having a pipe top end and a pipe bottom end, a pivoting operating lever having a spigot a valve having a drain port, and a pipe connector. The hollow boot body has a first housing and a second housing attached to form a boot body with a boot cavity, base drainage slots, side drainage slots, water drainage louvers, raised louvers, and input and output ports. The hydrant drainage boot is enclosed around at least the valve, the pipe connector, a water supply line and a portion of the riser pipe of the frost-free hydrant.

  • Patent number: 9221262
    Abstract: Operation of a carriage is controlled to actuate a mechanism. The carriage is controlled according to a feed forward term and a feedback term, to compensate interaction of the carriage with the mechanism. Thus, the carriage is to engage the mechanism at a reduced velocity for quiet operation, and fully and reliably actuate the mechanism without stalling the carriage.

  • Patent number: 7692399
    Abstract: A method of controlling a DC motor is presented. In a determining action, a thermal power dissipation is determined from a motor input and a motor velocity. In another determining action, a motor temperature is determined based on a thermal model using the thermal power dissipation.

  • Patent number: 6942406
    Abstract: A media handling system for handling sheets of media. The system includes a pick roller having a circumferential media-contacting surface and arranged for rotation about a roller axis to contact and pick a sheet from an input source. A drive roller rotates about a drive roller axis, with a media path extending between the pick roller and the drive roller. A first guide structure is positioned along a first longitudinal edge of the media path and providing a first media guide surface. A second guide structure is positioned along a second longitudinal edge of the media path and provides a second media guide surface. The first and second guide surfaces are positioned to constrain the movement of a media sheet in the media path between the pick roller and the drive roller, thereby alleviating trailing edge print defects.

  • Patent number: 6682167
    Abstract: A method for reducing a servicing noise is provided. In a measuring action, a servicing position is measured using a full pushing force of an actuator applied to a service station. In a disengaging action, the actuator is disengaged from the service station. In a reducing action, the pushing force is reduced to a minimum value. In an engaging action, the service station is engaged with the actuator. In a monitoring action, a position of the actuator is monitored during the engagement. In a comparing action, the actuator position is compared to the stored servicing position. In an increasing action, the pushing force is increased for future engagements if the servicing position has not been reached. A printing mechanism configured to employ such a method is also provided.

  • Patent number: 6675561
    Abstract: A semi-automatic round baler having an “auto kick” or “auto wrap” mode. In the auto kick mode, at the conclusion of the forming cycle the baler will stop and await the operator's signal to continue. Once the operator has signaled to continue, the baler will wrap the bale and will immediately proceed to the ejecting cycle. In auto wrap mode, the baler will automatically enter into and complete the wrapping cycle (after a short delay) following completion of the forming cycle. At the conclusion of the wrapping cycle in the auto wrap mode, the baler will await the operator's signal before ejecting the completed bale.
