    • The invention provides methods and systems that control the application of a material onto micro-rough implant surfaces. Thus, the present invention provides method of applying crystalline nanoparticles onto the surface of an implant to produce an implant with a crystalline nanoparticle layer on its surface, the method comprising: providing an implant substrate body; applying crystalline nanoparticles onto the surface of the implant; and rotating the implant, to produce an implant with a crystalline nanoparticle layer on its surface. This method of nanoparticle application is designed to promote the integration of implants, such as dental and orthopedic screws, into living tissue, and offers the ability to control the thickness and uniformity of the nanoparticle layer, in one or several layers, while simultaneously retaining the microroughness of the implant. Further provided are systems for applying crystalline nanoparticles onto the surface of an implant and implants having a crystalline nanoparticle layer on their surfaces.
    • 本发明提供了控制材料在微粗植入物表面上的应用的方法和系统。 因此,本发明提供了将结晶纳米颗粒施加到植入物的表面上以在其表面上产生具有结晶纳米颗粒层的植入物的方法,所述方法包括:提供植入物基底体; 将结晶纳米颗粒施加到植入物的表面上; 并旋转植入物,以在其表面上产生具有结晶纳米颗粒层的植入物。 这种纳米颗粒应用方法旨在促进植入物(如牙科和矫形螺钉)与活组织的整合,并提供一个或多个层面控制纳米颗粒层的厚度和均匀性的能力,同时保留 植入物的微粗糙度。 还提供了将结晶纳米颗粒施加到植入物的表面上的系统和在其表面上具有结晶纳米颗粒层的植入物。

    • A method and apparatus taught herein provide a digital-to-analog converter (DAC) for use in a conversion feedback path of a sigma-delta type analog-to-digital converter (ADC). The DAC uses current pulse shaping to generate a conversion feedback signal in each feedback cycle of the ADC that provides a consistent charge transfer for accurate digital conversion and has a controlled current pulse shape. In one or more embodiments, the DAC includes a capacitor circuit for charge storage and transfer and a (series) resistive circuit having variable resistance for current pulse shape control. In at least one embodiment, current pulse control limits a peak current of the conversion feedback signal, thereby reducing DC power consumption and gain-bandwidth (GBW) and slew rate requirements of the ADC's integration amplifier, and limiting residual (ending) current in each feedback cycle, which yields commensurate gains in (feedback cycle) clock jitter insensitivity.
    • 本文教导的方法和装置提供了用于Σ-Δ型模数转换器(ADC)的转换反馈路径中的数模转换器(DAC)。 DAC使用电流脉冲整形在ADC的每个反馈周期中产生转换反馈信号,提供一致的电荷转移以实现精确的数字转换,并具有受控的电流脉冲形状。 在一个或多个实施例中,DAC包括用于电荷存储和传输的电容器电路和具有用于电流脉冲形状控制的可变电阻的(串联)电阻电路。 在至少一个实施例中,电流脉冲控制限制了转换反馈信号的峰值电流,从而降低了ADC集成放大器的直流功耗和增益带宽(GBW)和压摆率要求,并限制了每个 反馈周期,其在(反馈周期)时钟抖动不敏感性中产生相当的增益。
