  • Fiber optic connector and method
    Patent number: 7891883
    Abstract: A fiber optic connector including a ferrule surrounding an optical fiber and a hub engaging the ferrule. The hub includes a front portion having first and second opposing surfaces and first and second tapered regions extending from the first and second opposing surfaces to a front face. A housing includes an anti-rotation seat configured to engage the first and second opposing surfaces, the anti-rotation seat including parallel first and second contact lines positioned at a front of the anti-rotation seat. A spring within a chamber of the housing biases the ferrule through a bore in the front of the housing. The first tapered region of the hub engages the first contact line and the second tapered region engages the second contact line when the hub and ferrule are in a first rotational position so that the optical fiber is maintained at a known orientation with respect to the connector.

  • On chip local MOSFET sizing
    Patent number: 7895550
    Abstract: A method for reducing variation in a desired property between transistors in an integrated circuit that is fabricated with a given process. The process is characterized to form a mathematical model that associates changes in polysilicon density and active density in the integrate circuit with changes in gate length and gate width in the transistors, and associates changes in the gate length and the gate width to the desired property. The integrated circuit is laid out with space sufficient to adjust the gate length and the gate width of the transistors without violating design rules of the transistors. The integrated circuit is divided into portions, and for at least a given one of the portions of the integrated circuit, the polysilicon density and the active density of the given portion is measured.

  • Method, device and computer-readable storage medium for network address association recovery
    Patent number: 7895318
    Abstract: Techniques for reestablishing network address associations upon recovery of a passive optical network (PON) disablement rely on storage address association information. A network node stores address association information in non-volatile memory upon detecting a network disablement. Upon recovery of the PON from the disablement, the network node associates network addresses to clients in accordance with the address association information. The network node may further verify the associations by sending ARP queries for the network addresses to the associated clients. Alternatively, the network nodes may reestablish the address associations by tracking the length of time of the network disablement, and updating address association information in accordance with the length of the disablement.

  • Secure payment card transactions
    Patent number: 7891563
    Abstract: Payment card transactions at a point of sale (POS) are secured in certain embodiments by intercepting, with a POS security layer installed on a POS terminal, payment data from the POS terminal, transmitting the payment data from the POS security layer to a server security application installed on a POS server, and providing false payment data from the POS security layer to a POS terminal application installed on the POS terminal. The false payment data in various embodiments is processed as if it were the payment data, such that the POS terminal transmits an authorization request to the POS server using the false payment data. In addition, the authorization request may be transmitted from the POS server to a payment gateway.

    Patent number: 7892639
    Abstract: Multi-layer, edge ingress, tamper- and solvent-indicating labels comprise a top film layer coated over a solvent, e.g., water, hydrocarbon, etc., and dye absorbing layer. The solvent and dye absorbing layer can be on top of a porous layer comprising a binder, pigment and particles of a solvent-soluble dye. The porous layer can be on top of an edge-wicking layer which itself is on top of a pressure-sensitive adhesive (PSA) layer. The edge-wicking layer both absorbs and transports solvent thus serving as a means for transporting solvent to the solvent-soluble dye.
