  • Publication number: 20090315767
    Abstract: A tracking device is disclosed for communication of location coordinate information. In one embodiment, the tracking device includes a signal transceiver device, a location coordinate acquisition device, and a computational processor activated and deactivated in accordance with a subscriber service usage profile. The location coordinate acquisition device generates a position fix of the tracking device and a signal transceiver device reports the position fix to a location tracking server. A flash memory device stores a zone management map. In accordance with a fix reporting period based at least in part on a subscriber service usage application including or accessing the subscriber service usage profile, an internal clock activates or deactivates the signal transceiver device, the computational processor, and/or the location coordinate acquisition device.

  • Publication number: 20090279888
    Abstract: An algorithm is disclosed for performing alien-wavelength channel balancing on channels between optical network elements within an optic-fiber communications system. The algorithm determines initial values of various optimization parameters for each of the channels, such as the input launch power and operating conditions of optical amplifiers in the optical path, and calculates an initial total optimization offset for the channels based on the initial values of the optimization parameters for each of the channels. The algorithm then adjusts the optimization parameters to new values and calculates a new total optimization offset based on the new optimization parameter values. The algorithm repeats this process until the relative channel launch powers and optical amplifiers are optimized.

  • Publication number: 20090269055
    Abstract: An algorithm is disclosed for performing channel balancing on channels between optical network elements within an optic-fiber communications system. The algorithm groups at least a portion of the channels into channel pairs, differentially adjusts the transmitter output power level of each of the channel pairs until the bit error ratio (BER) of at least one channel in each of the channel pairs exceeds a threshold, and records a respective power margin for each of the channels as the difference between the initial and final power levels. From the recorded power margins, a mean power margin is determined that is used to shift the transmitter output power level of each of the channels.

    Abstract: A presentation system comprises a personal computer (PC) (1) and a display arrangement (3). The display arrangement (3) includes a large main monitor (5) and four small satellite monitors (7a-7d) arranged around the main monitor. Each monitor (5, 7a-7d) is a thin-film transistor liquid crystal display (TFT-LCD) and is separately connected to the PC (1) by a respective cable and video driver (not shown). An operating system is stored on the PC (1), as are two application programs, referred to herein as the interactive process visualisation (IPV) program and the multi-monitor support (MMS) program. The IPV program is an application which enables the user to show a presentation in the main monitor (5). This presentation can include a range of media, such as images, animations, video streams and so on. In addition, the IPV program is arranged to run an executable command which invokes one or more instantiations of the MMS program.

  • Publication number: 20080179325
    Abstract: A closure assembly for a tank includes a cap shell and a cylindrical insert connected by a lost motion connection defining a first stop and a second stop for relative axial movement. A dome extends inwardly from the cylindrical insert and includes an orifice defining a valve seat. A stem includes a mating edge for engaging the valve seat. The mating edge abuts the valve seat and displaces the dome axially to seal the orifice at the first stop, and is spaced from the valve seat to at the second stop. Opening the valve allows vapor to vent from the tank along a tortuous path defined through an aperture and between the cap shell and the cylindrical insert. The aperture is open or sealed with the valve depending on the relative position of the cap shell and cylindrical insert.

  • Patent number: 7373362
    Abstract: A coordinating push and user-initiated synchronization method and system. Initially, changes to a local application data store are detected and records affected by the change are identified. At some point, a record affected by a detected change is pushed to a remote system where it is ascertained whether the pushed record, in its current form as affected by the detected change, has already been replicated in or deleted from a remote application data store through user-initiated synchronization. If not, the pushed record is used to update the remote application data store. Instead, at some point it may be ascertained whether the identified record, in its current form as affected by the detected change, has been replicated in or deleted from the remote application data store through push synchronization as just described. If not, the remote application data store is synchronized with the local application data store.

  • Publication number: 20080065498
    Abstract: A technique is disclosed for interfacing business processes with telephony functions. Particularly, an orchestration engine is interposed between a business process engine that executes business processes and an enterprise telecommunications network that executes telephony functions. Acting as an intermediary between the business process engine and the telecommunications network, the orchestration engine decouples the atomic telephony functions that are required for a business application from the business logic that is used in features that comprise one or more business processes. Thus, a new protocol state, feature, or algorithm change is isolated to a single and easy-to-develop location in software.

  • Publication number: 20080018884
    Abstract: A method for intrusion detection in an optical fiber communication network. The method includes at a first location on an optical fiber segment, receiving a set of multiple optical signals having wavelengths differing from each other, measuring received signal power for each of the received multiple optical signals, and repeating the receiving and the measuring steps. Each optical signal in the repeated steps has same wavelength as corresponding received optical signal in the initial steps. The method further includes computing a signal power loss between each received optical signal in the repeated set and the corresponding optical signal in the initial set, fitting a curve of signal power loss vs. wavelength to the computed signal power losses using a statistical analysis, and if the signal power loss of the curve over a preselected wavelength band is at least as great as a preselected minimum loss level, providing intrusion notification.

  • Patent number: 7318687
    Abstract: An assembly comprises a male component and a female component which connect together to form a mechanical connection, the female component being adapted to at least partially receive an end portion of the male component. The female component has at least one bore which is adapted to receive a clamping pin which can be tightened to clamp the female component around the male component. A guide is provided which is carried by the male component and which defines at least one blocking region and one opening region, the opening region being aligned with the at least one bore in the female component to permit insertion of the clamping pin into the bore when the male component and female component are correctly aligned and the blocking region otherwise preventing insertion of the clamping pin when the male component is inserted into the female component with an incorrect alignment. The guide assists in achieving correct alignment of the male and female components during assembly.
