Abstract:
The present invention relates to elastic nonwoven materials comprising an elastic layer formed from a polymer blend comprising a propylene-based polymer and a minor amount of an ethylene-based polymer. The propylene-based polymer may comprise from about 75 to about 95 wt % propylene and from about 5 to about 25 wt % ethylene and/or a C4-C12 α-olefin, and may have a triad tacticity greater than about 90% and a heat of fusion less than about 75 J/g. The ethylene-based polymer may comprise from about 65 to about 100 wt % ethylene and from 0 to about 35 wt % of one or more C3-C12 α-olefins.

A magnetic recording head includes a trailing surface and a plurality of bonding pads arranged on the trailing surface and in a row adapted for both bonding and testing. Each of the bonding pads has at least one side portion being coated with electrically conductive solder nonwettable coat to prevent short circuit between the adjacent bonding pads. The invention also discloses a head gimbal assembly with the magnetic recording head and a disk drive unit having such head gimbal assembly.
Abstract:
A pulse width modulation (PWM) signal generator generates multiple output PWM signals from an input PWM signal. The output PWM signals are synchronized to synchronization events. Each output PWM signal has a duty ratio substantially equal to the duty ratio of the input PWM signal, and each output PWM signal has a fixed phase-shift in relation to the other output PWM signals. The PWM signal generator samples an input PWM cycle to determine sample parameters representative of its duty ratio. The sample parameters are then used to generate a corresponding output PWM cycle for each of the output PWM signals. In response to a synchronization event, the PWM signal generator prematurely terminates the current PWM cycle and initiates the next PWM cycle while ensuring that the portion of the current output PWM cycle completed by the leading output PWM signal up to the point of the premature termination is replicated for the corresponding output PWM cycles of the other non-leading output PWM signals.
Abstract:
A pulse width modulation (PWM) frequency converter converts an input PWM signal to an output PWM signal having a different frequency while maintaining a substantially equal duty ratio. The PWM frequency converter samples the input PWM signal for a PWM cycle using a sampling clock. A filter module filters the resulting set of one or more PWM parameters to compensate for noise introduced by potential clock mismatch, clock jitter, ambient variations, and other non-deterministic issues, thereby generating filtered PWM parameters. The sampling employed by the filter module compares a difference between the one or more current PWM parameters and previous (or historical) PWM parameters from an earlier sampled PWM cycle to a predetermined change threshold in determining a filtered set of one or more PWM parameters. The filtered set of one or more PWM parameters then is used to generate one or more corresponding PWM cycles of the output signal.
Abstract:
A photoluminescent or electroluminescent system and method of making a non-luminescent nanostructured material into such a luminescent system is presented. The method of preparing the luminescent system, generally, comprises the steps of modifying the surface of a nanostructured material to create isolated regions to act as luminescent centers and to create a charge imbalance on the surface; applying more than one polar molecule to the charged surface of the nanostructured material; and orienting the polar molecules to compensate for the charge imbalance on the surface of the nanostructured material. The compensation of the surface charge imbalance by the polar molecules allows the isolated regions to exhibit luminescence.
