Title: Method for determining optimal location and value of dispersion compensation modules in an optical network
Inventor: NG EDDIE KAI HO
IPC: H04B10/18
Filed: 2003-05-23
Granted: 2009-01-06
Abstract: A method for determining optimal locations and values of dispersion compensating modules (DCMs) in an optical network is provided. The method comprises repeatedly evaluating possible combinations of DCM values and locations and adding to the combination having the lowest score until a solution of DCMs is formed that satisfies the dispersion limits of the network. This method provides an optimal solution with, for example, the lowest value of DCMs necessary to meet dispersion specifications. In one embodiment, the method for determining the optimal location and value of the DCMs uses a priority queue to store the different combinations of DCM values and locations. Modifications to the method include variations in the score function, for example to minimize the total cost of the DCMs. In another embodiment, a series of priority queues are used to improve the efficiency of the method by reducing the amount of processing required to sort the priority queues.

Abstract: A needle shield (26) and needle shield assembly (20) are provided for preventing accidental needle sticks. The needle shield (26) includes opposing sidewalls and is pivotable between an open position that allows use of the needle cannula (30) and a closed position that covers at least the tip of the needle cannula (30). A locking member (60) extends from one of the sidewalls of the needle shield (26) and includes a relatively rigid base portion (60A) and a relatively flexible end portion (60B). The needle cannula (30) engages the relatively flexible end portion (60B) when entering the needle shield cavity (58), deflecting it with respect to the base portion (60A). Upon attempt to move the needle shield (26) from the closed position to the open position, the needle cannula (30) is directed by the locking member (60) towards the relatively rigid base portion (60A), thereby making it very difficult to reuse the needle cannula (30).

Abstract: An air flow producer mounted at the ceiling of a room generates an air flow toward the floor, reducing temperature gradients and improving heating and cooling efficiency. A housing defines a circular cylindrical, vertical flow passage that receives the air flow. A discharge chamber discharges the air flow through a grill toward the floor. The discharge chamber has a cross-section that expands progressively from the outlet of the flow passage to the outlet of the discharge chamber. The air flow through the housing is produced by a fan with a rotary blade assembly, and the blade assembly extends partially into the discharge chamber. The position of the blade assembly and the expanding cross-section of the discharge chamber cooperate to increase air flows through the housing. Optionally, an air intake chamber of generally inverted frustoconical shape may be mounted at the upper inlet end of the cylindrical flow passage to smooth flows further.
