  • Patent number: 8769654
    Abstract: A method is provided, including (a) upon a standard small form-factor pluggable (SFP) module being inserted into an SFP jack on a network host device, determining if the SFP module is a legacy device or a smart device, (b) upon determining that the SFP module is a legacy device, receiving a magic code from the SFP module and determining if the magic code is a valid magic code, and (c) upon determining that the SFP module is a smart device, performing a smart authentication process with the SFP module. Associated apparatuses and additional methods are also provided.
    Type: Grant

  • Patent number: 8340123
    Abstract: In one embodiment, a networking device may include a network port and be configured to receive a transceiver module card in the network port. The networking device may detect whether the transceiver module card is a single channel card or a multi-channel card, where the single channel card includes a single transceiver module and the multi-channel card includes multiple transceiver modules. The networking device may transmit data to the transceiver card either as a single channel de-multiplexed over multiple lanes or as multiple independent channels corresponding to the multiple lanes based on whether the transceiver module card is the single channel card or the multi-channel card. The networking device may transmit data over each of the lanes at one data rate regardless whether of the transceiver module card is the single channel card or the multi-channel card.

  • Patent number: 6301590
    Abstract: A method and apparatus are used to format and display data on the Web. A request is received on an application server from a Web client, a connection is established to a data repository via the application server, the data is retrieved from the data repository, formatted on the application server in a predetermined reporting format, and displayed on a display device coupled to the Web client.

  • Patent number: 5583507
    Abstract: A method and apparatus for passive identification includes a series of elements preferably in the form of strips, bars or other geometric shapes, or as dipole antennas made of a material having variable EM retro-reflectivity characteristics. By varying the characteristics of individual elements (i.e. spatial, polarization, frequency response and angular extent of retro-reflection), the elements form an alterable pattern which can be used for identification. The characteristics can be changed remotely, the ability of the device to understand and implement the change being a criterion for identification.
