  • Patent number: 9054783
    Abstract: Example methods, apparatus, and articles of manufacture to trigger preemptive maintenance of vectored digital subscriber line (DSL) systems are disclosed. An example method includes generating a trouble ticket for a first subscriber loop based on a result of a diagnostic test, the diagnostic test being performed on the first subscriber loop when a value representing crosstalk coupling between the first subscriber loop and a second subscriber loop exceeds a threshold. The first subscriber loop and the second subscriber loop belong to a vectored group of subscriber loops contained in a same cable binder. The example method includes submitting the trouble ticket.

  • Patent number: 8280549
    Abstract: An automated drug dispensing system includes a cabinet adapted to store a variety of prepackaged pharmaceuticals in a plurality of bins for filling patient prescriptions. Each bin stores a particular variety of packaged multiple-dose pharmaceutical. Each variety of pharmaceutical is associated with a particular code. A controller receives request signals and in response generates dispense signals. Each bin includes a dispenser coupled to the controller for dispensing the packaged pharmaceuticals therefrom in response to a dispense signal sent from the controller. After a package is dispensed, a code reader determines the code of the dispensed package and verifies whether the code on the dispensed package matches the code of the requested package.
