    • The present invention provides a method for determining consumption of appliances within a surveyed household in which there are no sensors for measuring consumption of specific appliances. The method comprises - pre-processing historical consumption of appliances in a group of sampled household, based on measurements performed by sensors associated with said appliances, in relation to profiles of households, including characteristics of each household and/or lifestyle of the occupants and environmental time dependent parameters, - detecting presence of an appliance in a surveyed household based on correlations between the household profile and consumption patterns based on sampled measurement taken at predefined discrete time periods such 1 minutes, - detecting periodic activation in the surveyed household based on detection of presence of each appliance, identified correlations to household profile and consumption pattern and - estimating consumption of each appliance is the surveyed households based on detection of periodic activation of each appliance, identified correlations to households profile and consumption pattern.

    • A current source is provided with two resistor banks, and digital potentiometers are used to control how much each resistor bank affects the resulting output current. Furthermore, when the digital potentiometers are at a particular setting such that a particular resistor bank does not affect the resulting output current (i.e., the resistor bank is "inactive"), the resistance of that resistor bank can be switched without affecting the output current, thus minimizing or eliminating discontinuities in the output current during a current sweep operation. Thus, for example, when a resistor bank meets its threshold and becomes inactive, the resistance of the inactive resistor bank may be switched, and then the digital potentiometer setting may be changed to facilitate smoothly reactivating that resistor bank, with the new resistance.
    • 电流源设有两个电阻组,数字电位器用于控制每个电阻组对结果输出电流的影响。 此外,当数字电位器处于特定设置时,使得特定的电阻器组不影响所得到的输出电流(即,电阻器组为“无效”),可以切换该电阻器组的电阻而不影响输出电流 ,从而在电流扫描操作期间最小化或消除输出电流中的不连续性。 因此,例如,当电阻器组满足其阈值并变为无效时,可以切换不活动电阻器组的电阻,然后可以改变数字电位器设置,以便利用新的电阻平滑地重新激活该电阻器组。

    • An audio fidelity meter (10) includes a scale (12) which uses colors to visually represent the fidelity of an encoded digital audio file based at least on its extracted bit rate. The bit rate is one of several digital audio quality descriptors. Other descriptors include format, source, bit width, and sample rate. The extracted bit rate is fed into a lookup table (18) for processing. One or more of the other descriptors can also be extracted and fed in combination with the extracted bit rate into the lookup table (18) for processing. The lookup table (18) stores information on various digital audio formats, sources and associated bit rates, bit widths and sample rates in the form of a database. The input bit width, sample rate, format, originating source and/or bit rate is/are compared against the database to generate a digital audio quality output. The output may be visually displayed via the scale (12), a fidelity meter needle (14) and an associated numerical bit rate display (16).
    • 音频保真度计(10)包括标尺(12),其使用颜色来至少基于其提取的比特率来视觉地表示编码的数字音频文件的保真度。 比特率是几个数字音频质量描述符之一。 其他描述符包括格式,源,位宽和采样率。 提取的比特率被馈送到查找表(18)中用于处理。 还可以提取一个或多个其他描述符并将提取的比特率结合进入查找表(18)以进行处理。 查找表(18)以数据库的形式存储关于各种数字音频格式,源和相关比特率,比特宽度和采样率的信息。 将输入位宽度,采样率,格式,发源和/或比特率与数据库进行比较以生成数字音频质量输出。 可以通过刻度(12),保真度计针(14)和相关联的数字比特率显示(16)来可视地显示输出。
