  • Patent number: 7714441
    Abstract: A microelectronic topography includes a dielectric layer (DL) with a surface higher than an adjacent bulk metal feature (BMF) and further includes a barrier layer (BL) upon the BMF and extending higher than the DL. Another microelectronic topography includes a BL with a metal-oxide layer having a metal element concentration which is disproportionate relative to concentrations of the element within metal alloy layers on either side of the metal-oxide layer. A method includes forming a BL upon a BMF such that portions of a first DL adjacent to the BMF are exposed, selectively depositing a second DL upon the BL, cleaning the topography thereafter, and blanket depositing a third DL upon the cleaned topography. Another method includes polishing a microelectronic topography such that a metallization layer is coplanar with a DL and further includes spraying a deionized water based fluid upon the polished topography to remove debris from the DL.

  • Patent number: 7702405
    Abstract: A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and any incoming data that follows that protocol will be sent onto the network. If the incoming data protocol does not match the network protocol, then the incoming data is not sent immediately to the network, but instead is sent to an input pin of a device upon the network specifically designed to receive that incoming data. The network, therefore, has ports that support both compliant and non-compliant incoming data, and the devices that produce such data.

  • Patent number: 7701959
    Abstract: Network devices of a digital network for communication between a plurality of devices have a source for transmitting data into the network, and sinks for receiving data from the network. Managers (logical controllers) to which priorities are assigned in a hierarchical order manage connections between sources and sinks. Before setting up a connection, a manager first queries a negotiation administrator to obtain a right to negotiate with other managers and to set up connections. When all other managers having higher priorities also have granted the connection, the manager connects sources and sinks.

  • Patent number: 7664214
    Abstract: A communication system, clock generation circuit, and method are provided for receiving jitter upon data and to generate a clock reference that does not contain the received jitter. The clock reference can be used either by a digital subsystem of a communication system node, or can be transmitted as substantially jitter-free data from that node to a downstream node of the communication system. Instead of recovering the clock reference from the data having jitter, a pattern is regularly defined within the data stream preferably at periodic, timed intervals. The data pattern may be made up of a series of non-transitions which, regardless of any jitter in the data itself, does not impute any jitter onto a phase-locked loop triggered from an edge of the non-transitioning data pattern. Using the edge as a reference point, a jitter-free clocking signal can be derived at the same frequency as a clocking signal which would normally be produced from the jitter-induced data.

  • Patent number: 7656167
    Abstract: An improved E-field generator including a slow-wave transmission line structure is provided herein. In some cases, the improved E-field generator may include an inductively-loaded slow-wave transmission line structure driven by a power source at one end of the structure and terminated by a load at the other end of the structure. In other cases, the improved E-field generator may include a capacitively-loaded slow-wave transmission line structure. In either case, the improved E-field generator provides a frequency-independent, significantly increased electric field at a distance spaced from the generator without altering the dimensions of the generator and/or the input power supplied to the generator. The increase in generated field intensity is achieved by decreasing the phase velocity of the electromagnetic wave propagating along the parallel elements of the generator.

  • Patent number: 7634694
    Abstract: A communication system for transmitting and receiving a sequence of bits, and the methodology for transferring that sequence of bits are provided. The communication system includes a transmitting circuit and a receiving circuit. Within the transmitting circuit is a scrambler that comprises a shift register, an enable circuit, and an output circuit. The shift register temporarily stores n bits within the sequence of bits, and the enable circuit enables the shift register to store bits that arise only within the payload section of a frame. The output circuit includes a feedback, and several taps within the n stages to scramble logic values within the sequence of n bits output from the shift registers thus effectively preventing in most instances the sequence of bits from exceeding n number of the same logic value. Within the receiving circuit is a descrambler also having a shift register, an enable circuit, and an output circuit. The descrambler recompiles the scrambled data back to its original form.

  • Patent number: 7620244
    Abstract: Various computer-implemented methods are provided. One method for signature recognition includes identifying a vertical element of a signature and determining a tilt angle of the vertical element. Tilt angle is defined by a line that is approximately parallel to the vertical element. In addition, the method includes determining a tilt factor. Tilt factor is defined as a horizontal offset between the tilt angle and a reference tilt as a function of distance from a signature baseline. The method further includes altering the signature using the tilt factor and comparing the altered signature to known signature(s) to determine if the altered signature matches one of the known signature(s). Another method includes altering the signature using a predetermined tilt factor and comparing the altered signature to known signature(s). If the altered signature does not match one of the known signature(s), these steps may be repeated with different predetermined tilt factors.

  • Patent number: 7609797
    Abstract: A communication system, clock recovery circuit, and method are provided for allowing data to be transmitted across a communication system and between clock recovery circuits absent a clock master specifically designed for one node of the communication system. Absent a clock master, the communication system is permitted to enter into an all slave mode, with periodic unlock conditions possibly rotating about the communication system ring topology. However, the unlock condition can be readily detected and if the received data bitstream formed into a recovered clock exceeds a threshold above or is less than a threshold below a reference clock generated during instances of unlock, then the clock recovery circuit will fix the synchronizing clock to the reference clock, and cause the bitstream to resynchronize to the reference clock before the reference clock is again disabled to allow the communication system to re-enter the all slave and rotating unlock condition.

  • Patent number: 7571389
    Abstract: A system and method are disclosed whereby two components within the Swing application program interface (API), JTextField and JPasswordField, are used to emulate the behavior of the TextField component in the abstract windowing toolkit (AWT). This allows legacy Java applications, based on the AWT, to be migrated to the platform-independent Swing API, without modification. In the AWT, a single TextField component could be used for ordinary text entry, as well as for password protected text entry. In the latter case, a prescribed echo character would be displayed as text was entered, to avoid displaying privileged information. According to the system and method disclosed herein, a JPasswordField component may be substituted for a JTextField component, or vice-versa, depending on whether an echo character has been specified. This substitution is performed at runtime, using an enhanced version of the Swing API, as disclosed herein. The enhanced version of Swing is referred to herein as AWTSwing.
