  • Patent number: 9376275
    Abstract: An automatic stack feeder having a moveable stack or product guide is disclosed. The automatic stack feeder may be configured to receive a stack of articles and a container enclosing a stack of articles. To ensure the stack of articles is properly supported following unloading from the container, the stack guide is moveable between a first and a second position, wherein the stack guide is in contact with the stack of articles while in the first position, and not in contact with the stack when in the second position.

  • Publication number: 20160001985
    Abstract: Embodiments of a system and method for shingulating, singulating, and synchronizing articles in an article feeder system are disclosed. The article feeder system may include a shingulating device configured to receive a stack of articles and to produce a positively lapped stack of articles, a plurality of picking devices configured to pick one or more articles from the positively lapped stack of articles and to produce one or more singulated articles, and one or more synchronization devices configured to deliver the one or more singulated articles to one or more sorter windows.

  • Publication number: 20150251221
    Abstract: Embodiments of a system and method for unloading articles from a container of items for use in an automatic stack feeder are disclosed. The automatic stack feeder may comprise a belt, a moveable lower paddle, and a moveable upper paddle, wherein the lower paddle is configured to partially extend through a belt of the automatic stack feeder. The movement of the belt, the lower paddle, and the upper paddle are coordinated such that there is no need to interrupt the operation of the automatic stack feeder to unload the container.

  • Publication number: 20150251862
    Abstract: A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.

  • Publication number: 20070183930
    Abstract: A self-contained, optical hand-held diagnostic device is provided with a body having a pocket-sized form factor sized and shaped for engagement by a user's hand. The body includes an integral power supply and an integral display. A channel receives reagent sample media in an indexed fit. The sample media has a plurality of spaced test areas which change color according to an amount of a constituent or property in the sample. Imagers are located within the body so that each of the imagers is superposed with one of the test areas when the sample media is indexed within the channel, to capture an image thereof. A processor is coupled with the imagers to analyze the captured images. The processor also derives a diagnosis value from the analysis, and generates an output corresponding thereto. The display is configured to receive and display the output.

  • Publication number: 20050237531
    Abstract: A miniature readhead for a photometric diagnostic instrument includes a housing of hand-held form factor, configured for receiving reagent sample media therein. The sample media has a plurality of test areas configured to react with, and change color, according to an amount of an analyte in a sample. The holder is sized and shaped for forming an indexed fit with the sample media and includes an array of light sources coupled to the housing, each of the light sources configured to emit light onto a respective one of the test areas. An array of chambers respectively containing an array of light detectors, is configured to enable each of the light detectors to receive diffuse, non-specular reflections of the light from the test areas, while substantially preventing the light detectors from receiving specular reflections of the light.
