    • A sigma-delta analog-to-digital converter (10) having DEM (14) facilitated data weighted averaging to select specific unit elements of a negative feedback loop digital-to-analog converter (15), which DEM (14) is comprised substantially of transmission gates that contribute little to propagation delay. As a result, the feedback signal provided by the feedback loop is not more than one clock cycle behind the present coded output of the ADC (10) itself. As a result, higher resolution converters can be realized. The DEM (14) utilizes a repeating sequence to select specific unit elements. In some embodiments the direction of sequence usage is reversed in various ways to aid in reducing harmonic distortion.
    • 具有DEM(14)的Σ-Δ模数转换器(10)便于数据加权平均以选择负反馈回路数模转换器(15)的特定单元,该DEM(14)基本上包括 对传播延迟贡献很小的传输门。 结果,由反馈回路提供的反馈信号在ADC(10)本身的当前编码输出之后不超过一个时钟周期。 因此,可以实现更高分辨率的转换器。 DEM(14)利用重复序列来选择特定的单元。 在一些实施例中,序列使用的方向以各种方式颠倒以帮助减少谐波失真。

    • Embodiments of the present invention generally provide a plasma source apparatus, and method of using the same, that is able to generate radicals and/or gas ions in a plasma generation region that is symmetrically positioned around a magnetic core element by use of an electromagnetic energy source. In general, the orientation and shape of the plasma generation region and magnetic core allows for the effective and uniform coupling of the delivered electromagnetic energy to a gas disposed in the plasma generation region. In general, the improved characteristics of the plasma formed in the plasma generation region is able to improve deposition, etching and/or cleaning processes performed on a substrate or a portion of a processing chamber that is disposed downstream of the plasma generation region.

    • Correcting a temperature measurement of a target sensed at one temperature sensor in an asset tracking device by using another temperature sensor. The asset tracking device includes at least one heat source that affects the temperature sensor for sensing the temperature of the target. The other temperature sensor measures temperature at a location in the asset tracking device. The relationships between an actual temperature of the target and the temperature measured at the two sensors are established through experiments or model. Using the relationships, the measured temperature of the target can be corrected to obtain a corrected temperature of the target.
    • 通过使用另一个温度传感器来校正在资产跟踪装置中的一个温度传感器处感测到的目标的温度测量。 资产跟踪装置包括影响温度传感器以感测目标温度的至少一个热源。 另一个温度传感器测量资产跟踪设备中某个位置的温度。 通过实验或模型确定目标实际温度与两个传感器测得的温度之间的关系。 使用这些关系,可以校正目标的测量温度以获得目标的校正温度。
