  • Publication number: 20100165699
    Abstract: Techniques and circuitry are disclosed for efficiently implementing programmable memory array circuit architectures, such as PROM, OTPROM, and other such programmable non-volatile memories. The circuitry employs an antifuse scheme that includes an array of memory bitcells, each containing a program device and an antifuse element configured with current path isolation well and for storing the memory cell state. The bitcell configuration, which can be used in conjunction with column/row select circuitry, power selector circuitry, and/or readout circuitry, allows for high-density memory array circuit designs and layouts.

  • Patent number: 7630852
    Abstract: A method for analyzing IC system performance. The method includes receiving system variables that correspond to an IC system; normalizing the system variables; using an infinite dimensional Hilbert space, modeling a system response as a series of series of orthogonal polynomials; and, solving for coefficients of the series of orthogonal polynomials. A system equation or a simulated response may be used to solve for the coefficients. If a simulated response is used, the coefficients may be solved by using the statistical expectance of the product of the simulated system response and the series of orthogonal polynomials. Alternatively, a simulated system response may be used to generate coefficients by performing a least mean square fit.

  • Patent number: 7593364
    Abstract: A method is disclosed to operate a wireless network (20) with a MS (100) and includes, in response to detecting that the MS has changed its location in the wireless network, registering the MS with a BS (45) to indicate the current location of the MS and, in response to the MS registering with the BS, triggering the sending of messages in the wireless network until information that is indicative of the current location of the MS is recorded by an AAA server (80). The AAA server can be subsequently queried to obtain the current location of the MS, such as when a network initiated data session (NIDS) for the MS is initiated. Also disclosed is a method to page a MS by, in response to the initiation of a NIDS for the MS, querying a home AAA server for a current BS/PCF/PDSN affiliation of the MS and sending a page message to the MS in accordance with the current BS/PCF/PDSN affiliation of the MS.

  • Patent number: 7333454
    Abstract: A system for handing off a mobile node includes a mobile node and a target foreign agent. To effectuate a handoff of the mobile node from an anchor foreign agent to the target foreign agent, a tunnel can be established therebetween such that data packet(s) sent between the mobile node and a correspondent node pass between the target foreign agent and the anchor foreign agent through the tunnel. After the tunnel is established, the mobile node can register with the target foreign agent to thereby bind the mobile node to the target foreign agent such that data packet(s) sent between the mobile node and the correspondent node pass through the target foreign agent to the correspondent node independent of the anchor foreign agent and the tunnel. Thereafter, the target foreign agent can close the tunnel between the target foreign agent and the anchor foreign agent.

  • Publication number: 20070091900
    Abstract: A method is provided for transmitting data, wherein control packets are given priority with respect to application data packets. In general, this is accomplished by establishing a separate, distinct link flow over which only control packets (e.g., TCP control packets) will be transmitted. A higher priority is associated with this link flow. In addition, the reliability of control packets sent over the dedicated link flow can be improved upon by increasing the number of retransmissions associated with the control packets and/or decreasing the window of time before the retransmissions are sent. A system, mobile terminal, network entity, and computer program product for implementing the method are also provided.

  • Publication number: 20070079995
    Abstract: A drill bit includes a bit body having a face on which two different types of cutting elements are disposed, the first type being cutting elements suitable for drilling at least one subterranean formation and the second type being cutting elements suitable for drilling through a casing bit disposed at an end of a casing or liner string and cementing equipment or other components, if such are disposed within the casing or liner string, as well as cement inside as well as exterior to the casing or liner string. The second type of cutting elements exhibits a relatively greater exposure than the first type of cutting elements, so as to engage the interior of the casing bit and, if present, cementing equipment components and cement to drill therethrough, after which the second type of cutting elements quickly wears upon engagement with the subterranean formation material exterior to the casing bit, and the first type of cutting elements continues to drill the subterranean formation.

  • Patent number: 7197026
    Abstract: A method and system for improving the efficiency of radio communication by optimizing at the radio link protocol (RLP) layer. When TCP segments are passed down from the TCP layer at a sending device, they are accompanied by TCP segment information such as TCP segment length or TCP segment number. The RLP layer receiving the data stores the TCP-segment information along with the data, and divides the data into frames for transmission. Using the TCP information, when the RLP layer receives a NAK indicating loss of an RLP frame for which retransmission will not occur, the RLP layer drops not only that frame, but also any other buffered frames associated with the same TCP segment with which the lost frame was associated, regardless of whether the other frames have been transmitted.
