    • An ultra sensitive method for detection of biomolecules includes the step of providing a plurality of bioreceptor functionalized nanoparticle probes. The nanoparticles can include metal, semiconductor, radioactive isotope or fluorescent dye molecules. A sample solution suspected of including the target is contacted with the probes, wherein if present, the target binds to the bioreceptor. After such binding a separating step follows. In the separating step, probes having the target bound thereto are separated from probes not having the target bound thereto. In one embodiment probes having the target bound thereto are then decomposed to generate ions, or broken into discrete radioactive isotopes or fluorescent dye molecules to form a solution including a large plurality of metal ions, radioactive isotopes or dye molecules. A concentration of ions, radioactive isotopes, or dye molecules in the solution is then determined and using this information the concentration of the target in the original sample solution is determined.
    • 用于检测生物分子的超灵敏方法包括提供多个生物受体官能化纳米颗粒探针的步骤。 纳米颗粒可以包括金属,半导体,放射性同位素或荧光染料分子。 将涉及包含目标物的样品溶液与探针接触,如果存在,则靶标与生物受体结合。 在这种结合之后,分离步骤如下。 在分离步骤中,将与其结合的靶的探针从不具有与其结合的靶的探针分离。 在一个实施方案中,将与其结合的靶标的探针然后分解产生离子,或者分解成离散的放射性同位素或荧光染料分子,以形成包含大量金属离子,放射性同位素或染料分子的溶液。 然后确定溶液中离子,放射性同位素或染料分子的浓度,并使用该信息确定原始样品溶液中靶的浓度。

    • Method and apparatus for generating a random number, such as for use in a security protocol to control access to a data processing system. A processor generates the random number in relation to a back electromotive force (BEMF) value. The BEMF value is preferably obtained in response to application of current to a circuit. The circuit preferably comprises a coil and the application of current preferably induces a relatively small movement of the coil. The random number is preferably a multi-bit digital value, and each bit of the random number is determined in relation to whether the corresponding BEMF value is even or odd. The coil preferably comprises a coil of a voice coil motor (VCM) used to position a transducer adjacent a rotatable storage medium, and the random number is preferably generated while the medium is in a non-rotatable state.

    • A method for generating a velocity command for an actuator assembly is provided. The actuator assembly includes an actuator arm, which is to move over a plurality of surfaces. The method begins by providing a compensation torque for each of the plurality of surfaces. A position of the actuator arm is determined so that it may be mapped to one of the plurality of surfaces, which is the present surface over which the actuator arm is moving. A target velocity is then provided for the actuator arm and input to a controller, which generates a velocity command from the target velocity and a selected compensation torque, which is the compensation torque of the present surface.

    • Apparatus in a disc drive for improving resistance of a disc drive disc stack to radially directed mechanical shocks. A disc is disposed about a rotatable spindle motor hub. Opposing first and second disc support members (such as a disc clamp, disc spacers, or a hub flange) circumferentially extend about the outer hub surface and cooperate to apply a clamping force to the disc to secure the disc relative to the spindle motor hub. The disc support members each comprise a circumferentially extending ring of high friction material having a contact surface that axially extends toward the disc. The clamping force applied to the disc is localized at the rings and at nodes extending from the disc support members so that respective gaps are formed between the disc and remaining portions of the disc support members, thereby reducing radial disc slip, increasing disc dampening, and reducing the likelihood of disc coning and warping.
    • 磁盘驱动器中的装置,用于改善盘驱动盘堆叠对径向定向机械冲击的阻力。 盘围绕可旋转的主轴电机集线器设置。 相对于第一和第二盘支撑构件(例如盘夹,盘间隔件或轮毂法兰)围绕外毂表面周向延伸并且协作以将夹紧力施加到盘以相对于主轴电机毂固定盘。 盘支撑构件各自包括周向延伸的高摩擦材料环,其具有朝向盘轴向延伸的接触表面。 施加到盘的夹紧力定位在从盘支撑构件延伸的环和节点处,使得在盘和盘支撑构件的剩余部分之间形成相应的间隙,从而减小径向盘滑动,增加盘衰减,以及 减少光盘锥形和翘曲的可能性。
