Abstract: Example embodiments relate to medication compliance alert devices. An example embodiment includes a method. The method includes capturing information about a medication label associated with a medication. The method also includes analyzing, by a first computing device, the information about the medication label to extract medication information. Further, the method includes generating, by the first computing device, a medication schedule for a corresponding patient associated with the medication.

Abstract: In one embodiment, a first router determines whether an interface coupling the first router to one or more second routers is transit-only. When the interface is transit-only, the first router generates an Open Shortest Path First (OSPF) Link State Advertisement (LSA) that includes an address for the interface and a designated network mask. The designated network mask operates as a transit-only identification that indicates the address should not be installed in a Routing Information Base (RIB) upon receipt of the OSPF LSA at the one or more second routers. When the network is not transit-only, the first router generates an OSPF LSA that includes the address for the interface but does not include the designated network mask, to permit installation of the address in a RIB upon receipt of the OSPF LSA at the one or more second routers.

Abstract: In one embodiment, a Link State Advertisement (LSA) is received from a first router in a network at a second router in the network. The LSA advertises an address of an interface of the first router. The second router determines whether the LSA includes a transit-only identification that indicates the interface of the first router is a transit-only interface. If the LSA does not include a transit-only identification, the second router installs the advertised address of the interface of the first router in a Router Information Base (RIB) of the second router. If the LSA does include a transit-only identification, the second router declines to install the advertised address of the interface of the first router in the RIB of the second router.

Abstract: In one embodiment, a network node of a secondary network receives a message from a multi-homed network. The message includes a block of network addresses allocated to the multi-homed network. It is determined that a primary network has advertised an aggregated route including the multi-homed network's allocated block of network addresses. Advertisements of the multi-homed network's allocated block of network addresses are suppressed, after a determination that the primary network has advertised an aggregated route including the multi-homed network's allocated block of network addresses. It may be later be determined that the multi-homed network has lost network connectivity via the primary network. Advertisements of the multi-homed network's allocated block of network addresses are unsuppressed, after a determination that the multi-homed network has lost network connectivity via the primary network.

Abstract: A system for hiding transit-only interfaces in a network. When a routing system is advertising a transit-only interface, the advertisement is marked to indicate the address is a transit-only interface. A routing system receives the advertisement and detects the identifier of the transit-only interface and does not store the address in the Router Information Base of the routing system.

Abstract: Systems and methods for obtaining corrected time information in a GPS-enabled device connected to a mobile handset via a short-range wireless network, such as a Bluetooth™ Piconet™. The mobile handset includes a GPS time and a network clock synchronized with a network clock in a short-range wireless network interface in the GPS-enabled device. The GPS-enabled device may send requests for time information to the mobile handset. The mobile handset receives the request and latches the network clock time and the GPS time. The captured network clock time and GPS times are sent to the GPS-enabled device in response to the request. The GPS-enabled device subtracts the captured network clock time from its own network clock time and adds the difference to the captured GPS time to obtain a corrected GPS time.
