摘要:
Method and apparatus for reducing intra-channel distortions of received data resulting from non-linear signal propagation includes parallel detection subcircuits for determining output values of sequentially provided optical data bits such that each of the sequentially provided optical data bits is processed by only one of the parallel detection subcircuits. Two parallel detection subcircuits process the input optical data bits according to even valued and odd valued clock signals. Each subcircuit has first and second signal analyzers to detect the value of the input optical data bit and a first memory unit and a second memory unit connected to the first and second signal analyzers. The input value of clock information provided to the first and second memory units of the first parallel subcircuit are 180° out of phase with input values indicative of a clock speed provided to the second parallel subcircuit.

Method and apparatus for data recovery in optical transmission systems include parallel detection subcircuits for determining output values of sequentially provided optical data bits such that sequentially provided optical data bits are alternately processed by respective ones of the parallel detection subcircuits. For example, in one embodiment of the present invention, clock values to be used for timing provided to the first parallel detection subcircuit are 180° out of phase with clock values provided to the second parallel detection subcircuit, such that the first parallel detection subcircuit and the second parallel detection subcircuit alternately process input optical data bits according to odd valued clock signals and even valued clock signals. Furthermore, the outputs of the parallel detection subcircuits are connected crosswise to provide control signals for their parallel counterparts. In principle, various decisions are made using decision circuits and desired output values are selected based on the previously decided bits.

摘要:
A multifunctional laundry sheet that comprises, and combines the benefits of, a color catcher, a fabric softener, and a fragrance is disclosed. The color catcher absorbs or traps loose dye in wash liquor during a typical wash cycle of a washing machine, thereby preventing the re-deposition of the dye to fabrics being washed therein, while the fabric softener enhances the appearance of fabrics during a typical drying cycle of an automatic dryer by decreasing static cling, increasing softness and fluffiness, or decreasing wrinkles, of the fabrics. Preferably, at least a portion of the catcher remains associated with the laundry sheet during the washing and imparts visual color change to the laundry sheet after the color catcher is affiliated with loose colorants in the laundry bath. It is also preferable that at least a portion of the fabric softener remains associated with the laundry sheet during the washing process so that the laundry sheet can be further used in a drying process to impart fabric conditioning benefits to the fabrics.

A nanomagnet having widely tunable anisotropy is disclosed. The disclosed nanomagnet is a magnetic particle with a convex shape having a first magnetically easy axis. The convex shape is modified to include at least one concavity to urge a second magnetically easy axis to form substantially offset from the first magnetically easy axis. In at least one embodiment, the convex shape is also modified to include at least one concavity to urge a second magnetically easy axis to form with a magnetic strength substantially different from the first magnetically easy axis.
