  • Patent number: 7867576
    Abstract: A method for monitoring the quality of a pattern of fluid beads applied to a moving substrate measures time delays between the passage of a reference point on a substrate element and leading and trailing edges of a bead, the quality of which is to be measured. A time delay ratio is generated, and compared to a reference ratio. The result of the comparison is indicative of variations in the quality of the measured bead. The invention has utility in a variety of industries, including industries in which adhesive beads are applied to a substrate, such as the envelope and box industries. An apparatus in accordance with the invention may conveniently utilize non-contact sensors to monitor the passage of the substrate and beads, and further may advantageously monitor the leading edge of the substrate and leading and trailing edges of the beads.

  • Publication number: 20080081350
    Abstract: In vitro-differentiated retinal ganglion cells can be produced by exposing a mammalian retinal ganglion cell line to a protein kinase inhibitor. The differentiated retinal ganglion cells can be used to identify agents that protect retinal ganglion cells in vivo or in vitro from cell injury (including cell death) and agents that affect retinal ganglion cell ion channel activity.

  • Patent number: 4598982
    Abstract: An extendible mirror bracket housing is fastened onto the rear view mirror in the interior of a motor vehicle. The bracket housing slidably carries a bracket within an elongated channel formed in the housing. An extension mirror is pivotably fastened by a hinge to the bracket and may be extracted from the channel. Stop members preclude extraction of the bracket member from the channel. An additional extension mirror may be provided at the rear of the first mentioned extension mirror.

  • Patent number: 3967251
    Abstract: A memory module containing addressable memory devices, and the circuits necessary to address and drive these devices, is configured so that a trade-off between memory size and word length can be made by rewiring the backplane. Thus, a single memory module design can be used for a variety of computer memory applications. This is accomplished by incorporating on the module a complete set of addressing and signal driving circuits, and allowing for the control of these module components through a system of control lines wired through the backplane.
