  • Publication number: 20060156907
    Abstract: A system and method use an aligning device to align clock signals of two logic devices before data transfer between them. In this example, the aligning device aligns a clock signal of a sequencer with a clock signal of a storage device before the sequencer transfers data to the storage device. The aligning device includes a phase detector that receives a first reference clock signal, which is used to control the storage device, and a delayed signal, which is used to control the sequencer, and generates a comparison clock signal. The comparison clock signal is filtered before being used to control a phase of a second reference clock signal, which is related to the first reference clock signal. The phase controlled second clock signal is an aligning clock signal that is feed back to a delay device to produce one or more subsequent delay device clock signals that are aligned to the storage device clock or first reference clock signal.

  • Publication number: 20060077752
    Abstract: A system and method are used to allow high speed communication between a chip and an external device. The system and method include a PLL with multiple phased outputs configured to be controlled digitally, a deskew PLL configured to align a clock of controller circuitry to interface circuitry, and a phase interpolated voltage controlled delay line configured to phase shift incoming signals. Analog design techniques of phase interpolation accurately position clocks and strobe signals that are required for high speed interfaces. The high speed interface is for transmitting and receiving signals from the external device, for example, a DDR DRAM.

  • Patent number: 7023934
    Abstract: Method and apparatus for Min star calculations in a Map decoder. Min star calculations are performed by a circuit that includes a first circuit that performs an Min(A,B) operation simultaneously with a circuit that calculates a ?log(1+e?|A?B|) value. The sign bit of the A?B calculation is used to select whether A or B is a minimum. The A?B calculation is also used to select either ?log(1+e?|A?B|) or ?log(1+e?|B?A|) as the correct calculation. In order to hasten the selection of either ?log(1+e?|A?B|) or ?log(1+e?|B?A|) as the correct calculation the apparatus does not wait for the A?B calculation to complete. Any bit of the A?B calculation between the third bit and final (sign bit) can be used for the selection. If an incorrect value is selected a log saturation circuit may correct the value.

  • Publication number: 20050133486
    Abstract: A hand-held laser welding wand includes one or more removable filler media delivery extension tips. The wand is dimensioned to be grasped with a single hand, thus filler media of various types and forms may be supplied to the weld area on a workpiece using various types of delivery systems and methods, including fully automated, semi-automated, or manually. The filler media may be wholly or partially delivered via the filler media delivery passages. One or more of the extension tips may be inserted into the filler media delivery passages to efficiently, precisely, and robustly supply filler media of various types and forms to the workpiece weld area.

  • Publication number: 20050103755
    Abstract: A hand-held laser welding wand includes a reflection shield that reflects laser light that is reflected off a work piece surface away from the hand of a user of the hand-held laser welding wand. The shield also reflects the thermal radiation transmitted from the work piece toward the wand during the weld process. This will help guard against a user of the wand absorbing laser light that may be reflected off the work piece, as well as significantly reduce any heat that might be transferred to the wand as a result of the reflected laser light.

  • Patent number: 6886669
    Abstract: A method and device for suspending a wheel axle from a vehicle includes a unitary flexible member coupled between the vehicle and the wheel axle and to an electronic control unit. The flexible member is formed of a material that changes shape in the presence of electrical signals having a varying signal strength. The electronic control unit, upon receiving various suspension related inputs, transmits the electrical signals having the varying signal strength to the unitary flexible member to change the shape thereof in order to vary the stiffness of the flexible member and thus control the suspension of the vehicle.

  • Patent number: 6882117
    Abstract: An apparatus for producing multiple light displays comprises: a discrete light source emitting at least one primary color; a circuit for driving the light source; a flexible tether secured to the light source; a handle secured to the flexible tether; and a control actuator. The drive circuit produces each of multiple time-dependent drive signals. The handle enables a user to move the light source along a curvilinear path at the end of the tether, the time-dependent drive signal and movement of the light source together producing the light display. The control actuator enables the user, while moving the light source along the curvilinear path and without substantially interrupting movement of the light source, to (i) alter the time-dependence of the drive signal and/or (ii) select another of the time-dependent drive signals for driving the light source, thereby altering the light display.

  • Publication number: 20050015705
    Abstract: A method for parallel concatenated (Turbo) encoding and decoding. Turbo encoders receive a sequence of input data tuples and encode them. The input sequence may correspond to a sequence of an original data source, or to an already coded data sequence such as provided by a Reed-Soloman encoder. A turbo encoder generally comprises two or more encoders separated by one or more interleavers. The input data tuples may be interleaved using a modulo scheme in which the interleaving is according to some method (such as block or random interleaving) with the added stipulation that the input tuples may be interleaved only to interleaved positions having the same modulo-N (where N is an integer) as they have in the input data sequence. If all the input tuples are encoded by all encoders then output tuples can be chosen sequentially from the encoders and no tuples will be missed.

  • Publication number: 20040098662
    Abstract: Single stage implementation of min*, max*, min and/or max to perform state metric calculation in soft-in soft-out (SISO) decoder. This allows for calculation of state metrics in an extremely efficient, fast manner. When performing min or max calculations, comparisons are made using 2 element combinations of the available inputs. Subsequently, logic circuitry employs the results of the 2 element comparisons the smallest (min) or largest (max) input. The max or min implementations may be employed as part of the max* and/or min* implementations. For max* and/or min* implementations, simultaneous calculation of appropriate values is performed while determining which input is the smallest or largest. Thereafter, the determination of which input is the smallest or largest is used to select the appropriate resultant value (of the values calculated) for max* and/or min*. Various degrees of precision are employed for the log correction values within the max* and/or min* implementations.
