    • A direct conversion radio-frequency (RF) receiver includes a controller and an adaptive continuous-time filter. The adaptive continuous-time filter receives a multiple-bit control signal generated by the controller to adjust a characteristic of the continuous-time filter. The controller generates the multiple-bit control signal in response to process variation in the semiconductor material used to implement the controller and the adaptive continuous-time filter. A method for tuning an adaptive continuous-time filter comprises determining a RC time constant, converting the RC time constant to a digital word, comparing a select bit of the digital word to a respective bit of a predetermined reference word to generate a control bit, applying the control bit to an adjustable element to modify the RC time constant, repeating the determining, converting, comparing and applying steps until the control bits generate an output word and providing the output word to the adaptive continuous-time filter.
    • 直接转换射频(RF)接收机包括控制器和自适应连续时间滤波器。 自适应连续时间滤波器接收由控制器产生的多位控制信号,以调整连续时间滤波器的特性。 响应于用于实现控制器和自适应连续时间滤波器的半导体材料中的工艺变化,控制器产生多位控制信号。 一种用于调整自适应连续时间滤波器的方法包括:确定RC时间常数,将RC时间常数转换为数字字,将数字字的选择位与预定参考字的相应位进行比较以产生控制位, 将控制位应用到可调元件以修改RC时间常数,重复确定,转换,比较和应用步骤,直到控制位产生输出字并将输出字提供给自适应连续时间滤波器。

    • The anterior composite matrix dental restoration system provides a matrix for holding a composite filling material in place as it cures, and a tool for holding the matrix in place during the curing of the filling material. The matrix comprises a thin, flat, flexible, and transparent sheet of plastic material with parallel tubular extensions on the opposite ends. The distal ends of the specialized forceps tool are inserted into the tubular ends of the matrix and used to install, hold, and remove the matrix. The relatively small and narrow tool greatly increases the comfort of both patient and dentist or dental technician by precluding need to insert and hold the fingers in the mouth of the patient to install, hold, and remove the matrix. The matrices may be provided in different sizes, with at least the tubular end components being optionally color coded to indicate the corresponding size.
    • 前组合基质牙齿修复系统提供了一种用于在复合填充材料固化时保持复合填充材料的基质,以及用于在填充材料的固化期间将基质保持在适当位置的工具。 该基质包括薄的,扁平的,柔性的和透明的塑料材料片,其两端具有平行的管状延伸部分。 专用钳子工具的远端插入矩阵的管状末端,用于安装,保持和移除矩阵。 相对较小和狭窄的工具通过排除需要将患者的手指插入并保持在患者口中以安装,保持和移除基质,从而大大增加了患者和牙医或牙科技师的舒适度。 矩阵可以以不同的尺寸提供,至少管状端部件可选地被颜色编码以指示相应的尺寸。
