| 20090041029 | METHOD AND SYSTEM FOR MANAGING TRAFFIC IN FIBRE CHANNEL SYSTEMS - Method and system for routing fibre channel frames using a fibre channel switch element is provided. The method includes, inserting a time stamp value in a fibre channel frame that is received at a receive segment of the fibre channel switch element; determining if a timeout occurs after a frame arrives at a receive buffer; and processing the frame if the timeout occurred. The method also includes, determining if a delta time value, which provides an accumulated wait time for a frame, is present in frame data; subtracting the delta time stamp value from a global time stamp value and using the resulting time stamp value to determine frame timeout status in the fibre channel switch element. A timeout checker circuit declares a timeout after comparing a time stamp value that is inserted in a fibre channel frame with a programmed time out value and a global counter value. | 02-12-2009 |
| 20090046736 | METHOD AND SYSTEM FOR KEEPING A FIBRE CHANNEL ARBITRATED LOOP OPEN DURING FRAME GAPS - A method and system for keeping an arbitrated loop open during a frame gap using a fibre channel switch element is provided. The switch element includes a port control module having a receive and transmit segment, wherein the transmit segment activates a timer whose value determines a duration during which the arbitrated loop remains open; determines if a last frame from a sequence of frames from a source port has been transmitted; modifies the timer value if a higher priority frame for transmission is unavailable; and keeps the arbitrated loop open until the timer reaches a certain value. If a higher priority frame is available for transmission before the timer value is modified then the higher priority frame is transmitted and the timer value is re-initialized. | 02-19-2009 |
| 20090290584 | METHOD AND SYSTEM FOR CONFIGURING FIBRE CHANNEL PORTS - A fibre channel switch element for routing fibre channel frame is provided. The switch element includes a fibre channel port that can be configured to support plural data transfer rates. The data transfer rate may be 1 G, 2 G, 4 G, 8 G or 10 G. The switch element includes a clock configuration module for providing a clock signal that is based on the data transfer rate. A receive segment of the fibre channel port sends a signal to a transmit segment to avoid an under flow condition. The receive segment also waits for a certain frame length after a fibre channel frame is written and before the fibre channel frame is read, depending upon a data transfer rate of a source port. Multiple lanes may be configured as a single 10G multi lane port or as multiple individual ports. | 11-26-2009 |
| 20090296715 | METHOD AND SYSTEM FOR PROGRAMMABLE DATA DEPENDANT NETWORK ROUTING - A method and system for routing fibre channel frames using a fibre channel switch element is provided. The switch element includes, a look up table that is indexed by domain, area, a virtual storage area number and/or AL_PA values of frames entering the fibre channel switch element; and logic for generating a column select signal that is used to select a column from the look up table for frame routing information The switch element also includes logic for validating a frame route by performing word depth match. A register is used to load look up table entries and column entries are selected based on the column select signal. The method includes, indexing a look up table with plural fibre channel frame header values; selecting a table value for routing a fibre channel frame based on a column select signal; and routing the frame if a route is valid. | 12-03-2009 |
| 20100128607 | METHOD AND SYSTEM FOR BUFFER-TO-BUFFER CREDIT RECOVERY IN FIBRE CHANNEL SYSTEMS USING VIRTUAL AND/OR PSEUDO VIRTUAL LANES - A method and system for distributing credit using a fibre channel switch element is provided. The switch element includes, a wait threshold counter that is used to set up a status for a port that has to wait for certain duration to send a frame due to lack of buffer to buffer credit; a credit module that controls buffer to buffer credit for a transmit segment of the fibre channel switch element; and a virtual lane credit module with a counter that is incremented every time a frame assigned to a virtual lane is sent and decreased every time a VC_RDY is received. The method includes, determining if a VC_RDY primitive is received; and allocating credit to a virtual lane that is not at its maximum credit, after the VC_RDY primitive is received. | 05-27-2010 |

| 20090077736 | Lavatory System - A lavatory system is disclosed to include one or more integrated hand washing stations. Each hand washing station includes a basin, a faucet, a solenoid valve configured to control water flow to the faucet, and a electric hand dryer located adjacent the basin and the faucet so that the user of the washing station may use the faucet and the electric hand dryer without leaving the washing station. The electric hand dryer preferably includes an outlet to direct air across the associated basin so that any water that drips from the user's hands will fall within the basin. A control system may be provided to control activation of the fixtures such as the solenoid valve, the electric hand dryer, and/or soap dispenser. The control system may be configured, for example, to inhibit simultaneous activation of the solenoid valve and the hand dryer. A photovoltaic system may be provided to provide power to one or more of electrical fixtures. | 03-26-2009 |
| 20090321539 | SHOWERHEAD FOR EMERGENCY FIXTURE - An apparatus for controlling a flow of fluid in an emergency fixture is disclosed. The apparatus comprises a first control element at least partially located in the body and configured to impart rotation into the fluid flow. The second control element comprises an inlet that receives fluid, and an outlet that divides the fluid flow into at least a first portion and a second portion. The outlet comprises a first outlet portion and a second outlet portion. The first outlet portion guides the first portion of the flow out of the flow rotation element as an axial flow, and wherein the second outlet portion provides rotation to the second portion of the flow relative to the axial flow. | 12-31-2009 |
| 20100320292 | SHOWERHEAD FOR EMERGENCY FIXTURE - An apparatus for controlling a flow of fluid in an emergency fixture is disclosed. The apparatus includes a body and a control element at least partially located in the body and configured to impart rotation into the fluid flow. The control element includes an inlet that receives the fluid flow. The control element also includes a first outlet portion configured to guide a first portion of the fluid flow out of the control element as an axial flow and a second outlet portion configured to provide rotation to a second portion of the fluid flow relative to the axial flow. The first portion of the fluid flow exits the control element at a position downstream from the position that the second portion of the fluid flow exits the control element. | 12-23-2010 |
