International Classification:

H04B 1008

US Classification:

359110, 359117

Abstract:

A method is provided for verifying that optical signals are properly routed between inputs and outputs of an optical cross-connect according to the prescribed routing paths defined in the cross-connect map. More specifically, optical signals are independently tagged at the cross-connect input ports with connection verification messages containing identification information. Connection verification messages can include, among other information, a message identification, incoming and outgoing wavelength information, incoming and outgoing port information, a time stamp, user verification data, and so on. At the cross-connect output ports, the messages are retrieved (and optionally removed) from the optical signals so that the identification information from the retrieved messages can be compared to the routing defined in the cross-connect map. If an optical signal is verified as not being routed according to the prescribed connection defined in the cross-connect map, then remedial action, such as tearing down the connection, can be initiated. By applying the tag to the optical signal, cross-connections can be verified in cross-connect applications employing one optical signal (i. e.

International Classification:

H04J 1408

US Classification:

398 99, 398 75, 398 82

Abstract:

Station apparatus used at a Local Serving Office (LSO) and at one or more stations reduces contention for communication access over time slots and/or wavelengths and/or fibers of an optical facility. The station apparatus enables Space-Wavelength-Time Division Multiple Access (SWT-DMA) communications using a combination of two or more different communication modes selected from a group including (1) a space division multiplexed access (SDMA) mode which selects a fiber(s) of the optical facility, (2) a wavelength division multiplexed access (WDMA) mode which selects a wavelength(s) on a fibers, and (3) a time division multiplexed access (TDMA) mode which selects time slot(s) of a wavelength. Communication mode selection may utilize (1) out-of-band signaling, (2) optical tag signaling, or (3) time marker signaling over a wavelength of one or more of the optical fibers.

Abstract:

A system and method for automatically maintaining the security of an area. In one embodiment of the invention, several space area network elements may be placed near or in a circular pattern around an area to be kept space, such as a school. The space area network elements are devices including sensors to sense the presence of an unwanted object such as a gun. The space area network elements may also include a wireless communication unit so that when the presence of an unwanted object or gun is sensed, a third party entity such as a the police may be alerted. The space area network elements also include inter-element communication units that allow the space area network elements to share information and form a space area network. Additionally, the space area network elements may include a positioning system unit that obtains data related to the position of the space area network. By way of the positioning system unit, position information may also be communicated to the third party entity.

International Classification:

US Classification:

375259, 375377, 34031011, 340538

Abstract:

The present invention provides a burst mode power line data network system having at least one burst mode power line transmitter (BMPLT) and at least one burst mode power line receiver (BMPLR) for enabling signaling, telephony and data communications via power lines without using carrier frequencies. The BMPLT transmits line encoded bursts of information via a power line to the BMPLR which receives the line encoded bursts of information and has a maximum inter-packet idle time of only one bit between bursts. The invention permits the use of AC coupling in a receiver and results in outputting data with constant pulse widths irrespective of optical signal power levels, etc. In one embodiment, a receiver has a wide dynamic range, is highly stable, may be used over all frequencies of interest without developing high speed electronics or optical components, and has no sensitivity penalty as compared to existing burst mode/packet mode receivers. Because the receiver completely removes common signals, base line wander problems are also removed. The main advantages of the burst mode power line data network system of the present invention is that carrier frequencies and their harmonics are eliminated and therefore signals can be scaled at higher data rates; interference is minimized, since the total time the signals are present on the power line is dramatically reduced; and there is no need for clock recovery in homes and businesses, and therefore modules for implementing the system are inexpensive.
