Abstract: An apparatus, system and method for asynchronously reducing power in a power domain. In one embodiment, the method includes: (1) receiving a sleep command for the power domain, (2) receiving, upon receiving the sleep command, an affirmative retention status signal denoting that a retention area in the power domain has stored data, (3) receiving, upon receiving the sleep command, an affirmative isolation status signal that denotes that an isolation of the power domain has occurred and (4) providing a power domain off command to the power domain upon receiving at least the sleep command, the affirmative status retention signal and the affirmative status isolation signal. In another embodiment, multiple enable signals are employed to generate a “glitch-free” control for a power switch.

Abstract: Text input data for an electronic record may be aggregated and mapped to create composite text input data. A semantic event in the composite text input data may be automatically detected, and a text mining result database may be updated by adding an entry identifying the detected semantic event and a triggering semantic rule. An indication for the electronic record may then be transmitted to a back-end application computer server that also determines at least one parameter corresponding to a characteristic of the electronic record. The computer server may then execute a computerized predictive model to predict a future performance characteristic indicator for the electronic record based on the at least one parameter and the indication received from the text mining platform, wherein the future performance characteristic indicator is indicative of a likelihood of an actual value of the electronic record differing from a predicted value of the electronic record.

Abstract: A digitizer with increased dynamic range is provided by applying varying gains/attenuations to an input signal and feeding the resulting scaled signals to several conventional analog-to-digital converters to be digitized. The digitized version of the largest scaled signal which does not result in its respective analog-to-digital converter from saturating is selected by a multiplexer to be fed through as the digitizer output. Each of the gains(attenuations) differ by multiples of approximately 6 dB, since one bit in an ADC represents this value. The multiplexer outputs a digital sample size which is larger than that of the analog-to-digital converters and with the selected digitized version being output as the appropriate subset of the larger sample size to account for the gain(attenuation) of the selected signal. Preferably, this is used in a wideband receiver to increase the dynamic range of the receiver.
Abstract translation: 通过对输入信号应用变化的增益/衰减来提供具有增加的动态范围的数字化仪，并将所得到的缩放信号馈送到要数字化的几个常规模数转换器。 不会导致其相应的模数转换器饱和的最大比例信号的数字化版本由多路复用器选择作为数字转换器输出。 每个增益（衰减）差值大约为6 dB，因为ADC中的一位表示此值。 多路复用器输出的数字样本大小大于模数转换器的数字采样大小，所选择的数字化版本作为较大采样大小的适当子集输出，以考虑所选信号的增益（衰减）。 优选地，这用于宽带接收机以增加接收机的动态范围。
