Abstract: The invention provides for optical circulators which redirect light from port to port sequentially in one direction used to separate traffic in a bidirectional optical fiber transmission system. The invention provides for using two optical circulators in each span of bidirectional fiber so that the OSC channel can be transmitted in one direction opposite to the WDM channels.

Abstract: The invention is relevant to optical fiber transmission systems, and in particular, pertains to the transceiver cards in an optical fiber transport system. In particular the invention teaches an improved transceiver card architecture that allows high density, flexibility and interchangeability of functionality.

Abstract: A computer system and method for transmitting 10 Gigabit Ethernet (10GE) LAN signals over transport systems. Standard 10GE LAN signals are generated in any client IEEE 802.3 10GE LAN compliant interface. A transceiver receives the client 10GE LAN signal in the LAN format. The client 10GE LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client 10GE LAN signal to an internal electrical 10GE LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical 10GE LAN signal is then re-modulated into a second 10GE LAN signal. The second 10GE LAN signal is then transmitted to a transport system.

Abstract: A system generates a model of a workflow. The system begins by displaying on a computer screen a first flowgraph between two horizontal time lines representing two respective participants. The first flowgraph comprises a plurality of vertical directional line segments extending between the two horizontal time lines and representing respective communications or other actions between the participants. Next, the computer receives a selection of a second flowgraph for display between one of the two time lines and a third, horizontal time line representing a third participant. The second flowgraph comprises a plurality of vertical directional line segments extending between the one time line and the third horizontal time line and representing respective communications or other actions between the participants represented by the one and third time lines. Then, the computer displays the second flowgraph between the one and third time lines.

Abstract: Disclosed herein is a wrap for a sterile article. The wrap is a sheet which encases the article to be wrapped by means of at least two inward folds, forming panels atop the article to be shielded. One of these panels has attached to it a member which extends underneath the package from a point on the panel spaced from its inward fold line so that the article can be unwrapped by reaching under the wrapped article and grabbing the member. By pulling the member towards the user with the package oriented with the panel that is attached to the member away from the user, the package can be unwrapped without reaching over and contaminating the exposed sterile article.

Abstract: Apparatus and method for determining the water activity (Aw) of a water-caining composition, such as a food, within approximately 10 minutes, by rapidly establishing equilibrium between the water-containing composition and the atmosphere with which it is in contact while maintaining the temperature substantially constant and determining the dew point of this atmosphere, from which the water activity is calculable from the ratio of the partial water vapor pressure at the dew point to the vapor pressure of pure water at the temperature of the atmosphere with which the water-containing composition is in equilibrium.

Abstract: A single-use, nonwoven surgical gown having a bib at the chest area configured to provide a sterile hand support pocket in the aseptic zone and an additional barrier layer in the critical chest area to guard against microbial transmission. The bib may also be configured to provide a belt tunnel within which a wraparound belt may be attached and stored and which will allow for vertical adjustment of the belt while providing the surgical gown with a clear and unencumbered front. The bib is attached to the inside of the gown front with access to the hand support pocket and bib tunnel through appropriately located slits in the gown front.

Abstract: Bundles of fibres are sealed into gaps by surrounding them at the gap with a pool of a sealing material, and longitudinally vibrating the bundle to work the sealing material between the fibres. The fibres may be hollow fibres used for reverse osmosis.
