    • A disk drive includes a drive circuitry, a storage disk and a slider. The storage disk has a data surface, and the slider magnetically interacts with the storage disk to transmit a signal between the storage disk and the drive circuitry. The slider includes a leading surface, an opposed trailing surface, a data transducer positioned near the trailing surface, and a piezoelectric element. The piezoelectric element receives a driving voltage from the drive circuitry to adjust a distance between the data transducer and the data surface. The piezoelectric element can form a portion of the trailing surface. The slider includes a slider body that forms a portion of the trailing surface, and a portion of the piezoelectric element can be coplanar with the portion of the trailing surface formed by the slider body. Further, at least a portion of the piezoelectric element can be constrained by the slider body. The piezoelectric element can include an exposed surface that is substantially parallel with the leading surface. The slider body can have an element cavity that completely receives the piezoelectric element. In one embodiment, the piezoelectric element has only one substantially planar exposed surface.
    • 磁盘驱动器包括驱动电路,存储盘和滑块。 存储盘具有数据表面,并且滑块与存储盘磁性地相互作用以在存储盘和驱动电路之间传输信号。 滑块包括前表面,相对的后表面,位于后表面附近的数据换能器和压电元件。 压电元件从驱动电路接收驱动电压,以调整数据传感器与数据表面之间的距离。 压电元件可以形成后表面的一部分。 滑块包括形成后表面的一部分的滑块主体,并且压电元件的一部分可以与由滑块体形成的后表面的部分共面。 此外,压电元件的至少一部分可以被滑块体约束。 压电元件可以包括基本上与前表面平行的暴露表面。 滑块体可以具有完全接收压电元件的元件空腔。 在一个实施例中,压电元件仅具有一个基本平坦的露出表面。

    • A game controller operates in both a wired mode and a wireless mode, and is able to switch between these two modes without permanent disruption to an ongoing game. During a transition from one mode to another, a host gaming system detects when the controller is physically disconnected (for wired mode to wireless mode) or connected (for wireless mode to wired mode). Upon detection, the host gaming system stores the game data and user information and the game controller stores an identifier in its nonvolatile memory. The host gaming system and game controller then establish a new communication link. The game controller retrieves the identifier and submits it to the host gaming system, which uses the identifier to reassociate the game data and user information with the game controller as it begins operating in the new mode. This allows the player to continue game play without interruption.
    • 游戏控制器在有线模式和无线模式下操作,并且能够在这两种模式之间进行切换,而不会持续中断正在进行的游戏。 在从一种模式转换到另一模式的过程中,主机游戏系统检测控制器何时被物理断开(用于有线模式到无线模式)或连接(用于无线模式到有线模式)。 一旦检测到,主机游戏系统存储游戏数据和用户信息,并且游戏控制器将标识符存储在其非易失性存储器中。 主机游戏系统和游戏控制器随后建立了新的通信链路。 游戏控制器检索标识符并将其提交给主机游戏系统,主机游戏系统在新游戏开始运行时使用该标识符将游戏数据和用户信息与游戏控制器重新关联。 这允许玩家继续游戏,而不会中断。

    • Systems and methods for controlling the rise and fall times of USB signals for USB devices and peripherals are provided. The rise and fall times of USB peripherals can be controlled, or changed, in order to match the electrical characteristics of the USB peripheral to a USB host. By sweeping through a range of rise and fall times, and testing the reliability of USB output, optimal rise and fall times for the characteristics of a USB peripheral can quickly be determined. In one embodiment, the controllability of the rise and fall times is provided in firmware that changes at least one characteristic of the USB peripheral that affects the amount of current flowing during USB signaling.
