  • Patent number: 11505982
    Abstract: A device for a closure drive assembly can include: a moveable trolley, the trolley configured for movement along a track or a rail under drive by a drive component to move a closure between an open position and a closed position, the trolley including a body having a guiding surface; a rotating body having one or more camming surfaces, rotation of the rotating body about a rotation axis being supported by the guiding surface; and a lever having a lever camming surface configured to engage with one or more of the camming surfaces of the rotating body, wherein the lever is associated with an engagement member such that rotation of the lever moves the lever camming surface along the one or more rotating body camming surfaces to displace the engagement member, and wherein the engagement member is arranged to provide selective engagement between the moveable trolley and the drive component.

  • Publication number: 20220235597
    Abstract: A tensioning device for a door operating system includes a pulley carriage on which a pulley of the door operating system is mounted for rotation, the pulley carriage being movable relative to a track of the door operating system. The tensioning device further includes an adjuster configured to move the pulley carriage relative to the track and thereby alter a level of tension in a longitudinal drive component of the door operating system, the adjuster of the tensioning device being accessible from an end of the tensioning device facing a track operator end of the door operating system. The tensioning device also includes a resilient member operatively engaged with the adjuster, the resilient member configured to provide damping of forces experienced by the longitudinal drive component.

  • Publication number: 20040137605
    Abstract: The present invention provides methods and apparatus for performing biological reactions on a substrate surface that use a low volume of sample fluid, accommodate substrates as large as or larger than a conventional microscope slide, accommodate a plurality of independent reactions, and accommodate a substrate surface having one or more hydrogel-based microarrays attached thereto. The invention further provides an apparatus that allows introduction of fluids in addition to sample fluid into each reaction chamber via standard pipet tips and associated pipettor apparatus. The invention further an apparatus that increases reaction reproducibility, increases reaction efficiency, and reduces reaction duration.

  • Publication number: 20040043479
    Abstract: The invention relates generally to methods and apparatus for conducting analyses, particularly microfluidic devices. In preferred aspects, the devices are fabricated using ceramic multilayer technology to form devices in which parallel, independently controlled molecular reactions, such as nucleic acid amplification reactions including the polymerase chain reaction (PCR) can be performed. Additionally, the devices can include and comprise micro-gas chromatographs similarly fabricated from ceramics.

  • Patent number: 5904955
    Abstract: An electronic device in a cavity in a mold is encapsulated by a composite plastic having two materials placed, respectively, in sequential locations in a reservoir in the mold. The first material has desirable properties when in contact with the surface of the device, e.g., better adhesion. The second and different material has other desirable properties, e.g., mechanical strength, low moisture permeability, etc. The first location is first in line in a direction through the mold chambers to the cavity. The two-part encapsulant is injected into the cavity without significant turbulence so as to avoid much mixing of the two materials. This creates a boundary layer of the first material which preferentially applies a coating to the device while the second material substantially fills the bulk of the space in the mold cavity. A composite encapsulation is formed having overall superior properties.

  • Patent number: 5065428
    Abstract: A secure answering machine allows both secure and non-secure information to be recorded by incorporating a digital signal processor (DSP) and both a secure and non-secure RAM. The secure RAM is powered entirely by battery. The battery is then connected to the housing of the answering machine such that when the housing is tampered with, the power from the battery is shut off eliminating all information stored on the secure RAM. The secure RAM is only accessed using an encrypting code.
