  • OC3 delivery unit; low level maintenance bus
    Patent number: 6389013
    Abstract: A method of providing a back up communications link for control messages within a delivery unit. The primary means of transport for both network data and control data within the delivery unit is by means of ingress and egress buses between application modules of the delivery unit. However, control messages from a unit controller can also be delivered by means of a separate link, typically to a bus control module.

  • Teste masked pharmaceutical particles
    Publication number: 20020031552
    Abstract: Taste masked particles and chewable tablets made therefrom are disclosed. The taste masked particles comprise a core containing an active ingredient and a polymeric coating covering said core, said coating comprising a mixture of a) an enteric polymer; and b) an insoluble film forming polymer, the surface of said particle being free of active ingredient. The chewable tablets provide immediate release of the active ingredient.

  • OC3 delivery unit; unit controller
    Patent number: 6275499
    Abstract: A unit controller for a delivery unit that interfaces telecommunications media to a switching matrix. The unit controller is partitioned into “generic” units, that can be easily configured for use as a line/trunk processor in an OC3 delivery unit. The same unit controller can be adapted for use in other types of delivery units, as well as for higher level controller applications.

  • Microcrystalline cellulose particles having active core
    Patent number: 6149943
    Abstract: The present invention provides a core of predominately microcrystalline cellulose, on which an active drug is layered onto the core via solution coating. The coated particles have a narrower particle size distribution than coated granules provided by other processes. An optional final coating of a pharmaceutically acceptable polymeric coating is provided to provide tastemaking or controlled release, and protection of the drug-layered particles.
