| 20080201597 | WRITE-LEVELING IMPLEMENTATION IN PROGRAMMABLE LOGIC DEVICES - Circuits, methods, and apparatus for memory interfaces that compensate for skew between a clock signal and DQ/DQS signals that may be caused by a fly-by routing topology. The skew is compensated by clocking the DQ/DQS signals with a phase delayed clock signal, where the phase delay has been calibrated. In one example calibration routine, a clock signal is provided to a receiving device. A DQ/DQS signal is also provided and the timing of their reception compared. A delay of the DQ/DQS signal is changed incrementally until the DQ/DQS signal is aligned with the clock signal at the receiving device. This delay is then used during device operation to delay a signal that clocks registers providing the DQ/DQS signals. Each DQ/DQS group can be aligned to the clock, or the DQS and DQ signals in a group may be independently aligned to the clock at the receiving device. | 08-21-2008 |
| 20080291758 | READ-LEVELING IMPLEMENTATIONS FOR DDR3 APPLICATIONS ON AN FPGA - Circuits, methods, and apparatus for transferring data from a device's input clock domain to a core clock domain. One example achieves this by using a retiming element between input and core circuits. The retiming element is calibrated by incrementally sweeping a delay and receiving data at each increment. Minimum and maximum delays where data is received without errors are averaged. This average can then be used to adjust the timing of a circuit element inserted in an input path between an input register clocked by an input strobe signal and an output register clocked by a core clock signal. In one example, an input signal may be delayed by an amount corresponding to the delay setting. In other examples, each input signal is registered using an intermediate register between the input register and the output register, where a clock signal is delayed by an amount corresponding to the delay setting. | 11-27-2008 |

| 20090143786 | IMPLANTABLE DEVICE WITH ELECTROLYTICALLY DETACHABLE JUNCTION HAVING MULTIPLE FINE WIRES AND METHOD OF INTRODUCTION - Electrolytically detachable implantable devices and methods of delivering the same to a treatment site. An assembly includes an implantable device, such as a vaso-occlusive coil, a conductive deployment mechanism, such as a conductive pusher or wire, and a temporary connection between the deployment mechanism and the coil in the form of an electrolytically detachable junction. The detachable junction includes fine wires, e.g., stainless steel wires having a small diameter of about 0.00001″ to about 0.0025″, for example, about 0.0005″. The pusher or wire is used to deliver the implantable device through a catheter and to a desired location or treatment site. After the implantable device is properly positioned, electrical current is applied to the fine wires, thereby simultaneously disintegrating the fine wires and leaving the coil at the treatment site. | 06-04-2009 |
