    摘要： An extension to the Universal Serial Bus (USB) protocol that utilizes reserved bits in the OHCI Endpoint Descriptors to signal which root hub port(s) should transmit the data. Typically, all ports transmit (broadcast) data. The present invention encodes transmission information that can be used by the hardware to effectively control which port(s) need to be tri-stated. However, by setting, the “on” bits for all the ports, the present invention retains standard USB functionality. Also provided is a method to increase the bandwidth of low speed devices connected to the USB bus by increasing the data payload for such devices.

    摘要： A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of spiral tracks, wherein each spiral track comprising a high frequency signal interrupted at a predetermined interval by a sync mark. An offset r0 representing a difference between an axial rotation of the disk and an axial rotation of the spiral tracks is estimated. Radial dependent timing compensation values are generated in response to the estimated r0. A phase error is generated in response to the sync marks in the spiral track crossings. A control signal is generated in response to the phase error and the radial dependent timing compensation values, and a frequency of an oscillator is adjusted in response to the control signal.

    摘要： A composite nanoparticle, for example a nanoparticle containing one or a plurality of cores embedded in another material. A composite nanoparticle can be formed by a one step process that includes: ejecting material from a bulk target material using physical energy source, with the bulk target material disposed in a liquid. Composite nanoparticles are formed by cooling at least a portion of the ejected material in the liquid. The composite fine particles may then be collected from the liquid. A product that includes composite fine particles may be formed with laser ablation, and ultrashort laser ablation may be utilized so as to preserve composite nanoparticle stoichiometry. For applications of the composite fine particles, optical properties and/or magnetic properties may be exploited for various applications.

    摘要： A microactuator reference limit used to prevent over-accumulation of internal states may be set based on the microactuator's mechanical properties and is applied at the reference point to the microactuator servo subsystem. A microactuator variable input limit to prevent over-accumulation of internal states may be dynamically determined based on the difference between a signal corresponding to the maximum physical stroke of the microactuator and an estimated motion of the microactuator. Either configuration of servo system automatically ensures that all the internal states of the microactuator controller will not over-react and cause excessive overshoot, sluggish response, and/or saturation.
