  • Method and system for configuring fibre channel ports
    Patent number: 8005105
    Abstract: A fiber channel switch element for routing fiber channel frame is provided. The switch element includes a fiber 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 fiber 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 fiber channel frame is written and before the fiber channel frame is read, depending upon a data transfer rate of a source port. Multiple lanes may be configured as a single 10 G multi lane port or as multiple individual ports.

  • Modulated semiconductor DFB laser array with a MEMS-based RF switch
    Patent number: 8000368
    Abstract: Many approaches to tunable lasers use an array of DFBs, where each element of the array has a different wavelength. In some operations one element of the array is activated at a time depending on the desired wavelength. For modulated applications, an RF voltage is applied to a specific element of the DFB array, generally using an RF switch. In standard configurations, the demands on the switch are relatively difficult, generally requiring low RF insertion loss and good high frequency performance to 10 GHz. The DFB arrays are generally common cathode or common anode, depending on the type of the substrate used to fabricate the devices. Described herein is an array with a common cathode or anode configuration using a MEMS based switch that shorts the selected laser to RF ground. With this topology, preferably the off-state capacitance should be low with the MEMS switch.

  • Method and system for using extended fabric features with fibre channel switch elements
    Patent number: 7990975
    Abstract: A fibre channel switch element and method for routing fibre channel frames is provided. The switch element includes a receive segment that can add a virtual storage area network (“VSAN”) tagging header to frames that are received by the receive segment; and strip the VSAN tagging header before frames are sent to ports that do not support virtual fabric capability. The receive segment includes a table used for matching fabric extension parameters. An incoming frame's VSAN identity value is compared to a control word entry to generate a value used for routing the incoming frame. The table is used to determine if a frame is part of a virtual fabric. The routing table for each port is used to route frames and the routing table includes entries for supported virtual fabrics.

  • Multi-imaging automated inspection methods and systems for wet ophthalmic lenses
    Patent number: 7990531
    Abstract: A method for inspecting lenses, especially wet contact lenses provided in a volume of liquid inside a container is described. A first image of the lens at a first position in the container is obtained, the lens then being moved to a second position within the container where a second image is obtained. A computer algorithm processes the first and second images to compare features that have moved with the lens to those features that have not moved with the lens whereby lenses are rejected if a feature has moved with the lens but is not a normal feature of the lens.

  • Multilayer wave springs with different properties
    Patent number: 7985105
    Abstract: A circular or plate wave spring that maintains high conductivity under high operating temperatures is provided herein. This is possible due to, at least in part, the conductor being made from a bi-metallic or multi-metallic material which can include a high tensile strength material, such as steel, that maintains strength properties at elevated temperatures cladded with a layer of highly conductive metal, such as copper. The high tensile strength material helps maintain the contact force needed for good conductivity since highly conductive metals and alloys tend to lose their tensile properties at elevated temperatures. The connector is presented here as a wave spring providing inward or outward protrusions for a conductive pin and housing.

  • Enhanced polling method for preventing deadlock in a wireless communications system
    Patent number: 7974259
    Abstract: A method of polling in a wireless communications system includes prohibiting polling within a predetermined period and triggering a poll function while polling is prohibited. After the predetermined period has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that the poll function was triggered by a “Every Poll_SDU SDU” trigger, and selects a PDU to schedule for re-transmission to fulfill the poll function.

  • Spring clip safety IV catheter
    Patent number: 7972313
    Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

  • Use of surfactants in extraction procedures for silicone hydrogel ophthalmic lenses
    Patent number: 7968018
    Abstract: Methods of producing silicone hydrogel ophthalmic lenses include contacting one or more delensed silicone hydrogel ophthalmic lens with a liquid composition that contains alcohol, water, and a surfactant. The methods can be steps of an extraction/hydration procedure used in the production of silicone hydrogel contact lenses. In some examples, contacting silicone hydrogel ophthalmic lens products with a liquid composition that contains alcohol, water, and a surfactant can significantly reduce or prevent surface distortion of the ophthalmic lens resulting from the extraction procedure. Some methods include subsequently contacting the silicone hydrogel ophthalmic lens with a liquid composition consisting essentially of water and a surfactant.
