Various aspects of the disclosure generally relate to a collapsible storage container with multiple sleeves. In some implementations a two-sleeve variant is described. In some implementations a three-sleeve variant is described. Both variants may be used to contain appropriately sized and shaped objects, for example bread, maps, posters, blueprints, plans, etc.

Methods and systems for facilitating distribution of ringback files to caller devices are provided. A ringback file server may receive a request to associate a ringback file with a callee device and a caller device. Responsively, the ringback file server transmits a copy of the ringback file to the caller device, thus enabling the caller device to play out the ringback file when the caller device subsequently initiates a call to the callee device. Preferably, the ringback file is a high quality audio or video file. Thus, locally storing the ringback file at the caller device facilitates playout of high quality ringback media and also avoids requiring that the ringback file server stream ringback media in-band to the caller device.

In accordance with the teachings of the present invention, a system and method for extending reach in a passive optical network (PON) is provided. In a particular embodiment, a method for extending reach in a PON includes transmitting traffic at a first wavelength from a transmitter at a first optical network unit (ONU) in a PON and transmitting traffic at a second wavelength from a transmitter at a second ONU in the PON. The method also includes receiving the traffic in the first wavelength at a first input port of a multiplexer at a distribution node in the PON and receiving the traffic in the second wavelength at a second input port of the multiplexer at the distribution node. The method further includes forwarding the traffic in the first wavelength and the traffic in the second wavelength to an optical line terminal (OLT) in the PON.

A wastewater treatment includes an elevated aeration system. The aeration system is used to provide air and nutrients to biological growth in a wastewater treatment vessel, and to promote circulation of the support media used for the biological growth. The aeration system is elevated from the bottom of the reactor vessel by supports that extend from sidewalls of the vessel, or from suspension systems that hang the aeration system at a desired height. Silt, debris and sludge may be removed from the free space between the elevated aeration system and the vessel floor. Mechanical collection or removal devices may be positioned between the elevated aeration system and the reactor floor.

In accordance with the teachings of the present invention, an upgradeable passive optical network is provided. In a particular embodiment, an upgradeable optical network includes an upstream terminal and a distribution node. The upstream terminal is operable to forward a downstream signal comprising traffic in a first wavelength, the traffic in the first wavelength transmitted by a first transmitter at the upstream terminal. The distribution node is communicatively coupled to the upstream terminal and is operable to communicate the downstream signal from the upstream terminal to a first plurality and a second plurality of downstream terminals. The distribution node comprises a primary power splitter configured to create a plurality of copies of the downstream signal for communication to the downstream terminals. The distribution node is configured to facilitate the addition of a wavelength router at a section of the distribution node such that the wavelength router may be added to the distribution node without interrupting the communication of traffic through the network and such that the addition of the wavelength router allows for routing of traffic in a second wavelength transmitted by a second transmitter to be added at the upstream terminal, the traffic destined for the first plurality of downstream terminals; and routing of traffic in a third wavelength transmitted by a third transmitter to be added at the upstream terminal, the traffic destined for the second plurality of downstream terminals.
摘要:
A method and apparatus is described for determining the probability that an item will be available at a particular location at an expected time of transaction for the item. Variances for both reported and unreported sales rates of the item may be calculated. Probability distributions may be generated for these sales rates and a convolution performed to obtain the probability that the item will be available at the expected time of transaction.

The invention, as embodied herein, comprises an improved portable maritime scoring and simulation system that comprises three or more buoys that are deployed in an area of water selected for maritime combat training. Attached to each buoy are a global positioning system receiver, an RF radio system, an acoustic analysis system, and a microprocessor. The acoustic analysis system is designed to capture an acoustic signature of ordnance impacting the water with predetermined characteristics. The system includes an RF radio repeater system linked to a system controller to control and monitor the elements of the system. In operation, when an acoustic signature is captured by the acoustic analysis system, the RF radio system, in one embodiment, transmits the time of the capture along with the GPS location of the buoy to the RF radio repeater system linked to the system controller. When three or more buoys transmit a captured acoustic signature, the system controller computes the location of impact using a location process. The invention also includes an improved method of controlling the system.
摘要:
A method and apparatus for maintaining the voltage level of data signals supplied to an integrated circuit, such as a PCMCIA card, at the same level as power also provided to the integrated circuit. Circuitry for maintaining the voltages at the same level is preferably embodied within a system having a card controller integrated circuit, a power supply, and a peripheral card socket for receiving a removable PCMCIA card. The power supply is controlled by the card controller to provide power to the PCMCIA card through the card socket at a voltage level matching internal voltage requirements of the PCMCIA card. The card controller is connected directly to the PCMCIA card by a signal transmission line. Circuitry is provided for ensuring that the voltage of data signals transmitted along the data bus line to the PCMCIA card substantially match the voltage of power provided from the power supply to the PCMCIA card along a power supply line. In this manner, damage resulting from a power mismatch within the PCMCIA card is avoided.
