  • Patent number: 6894816
    Abstract: In a holographic digital data storage system, holographic page data has at least two concentric patterns with the optical information arranged within an outermost pattern of at least two concentric patterns. Since at least two concentric patterns in the holographic page data are deformed into at least two elliptic patterns in the diffracted beam caused by irradiation of the reference beam, at least two elliptic patterns are extracted from the diffracted beam and then at least two elliptic patterns are estimated to generate at least two estimated concentric patterns. A compensated vector between said at least two elliptic patterns and said at least two estimated concentric patterns is used to reconstruct the optical information from the diffracted beam.

  • Patent number: 6473455
    Abstract: A method compensates a phase delay of a clock signal used in a data communications system. First, a plurality of delayed clock signals are provided by modifying the amount of delay of the clock signal. In synchronization with one of the delayed clock signals, one or more test data signals and their address signals are sequentially issued and sent to a storage device. In synchronization with the original clock signal, each test data signal is stored in an area that its address signal indicates and then, upon receipt of the address signal at a predetermined time of the original clock signal, a data signal which corresponds to the address signal is read and sent to a controller. At a predetermined time of the delayed clock signal, a data signal is received from the storage device and it is checked whether or not each test data signal and the received data signal are the same.

  • Patent number: 6359795
    Abstract: A converter utilizing a multifilar transformer having its primary and auxiliary windings made simultaneously, a technique known as bifilar winding, provides high efficiency and low noise. The multifilar winding technique yields minimum leakage inductance between the windings and reduces the proximity effect to a minimum achievable using most well-known wires. The converter utilizes an improved soft-switcher topology which advantageously reduces the interwinding capacitance between the primary and auxiliary windings of the transformer. The topology includes a resonant LC circuit interposed in series with one leg of the auxiliary winding and the auxiliary switch. The other leg of the auxiliary winding is at ground. A controller is provided to control switch timing such that the converter optimizes switch loss and resonant pulse loss.
