Abstract: In accordance with this invention, a system and method of presenting and selecting information on providers of goods or services via a voice interactive device based upon a consumer's location are provided. A wireless indication of a consumer's location passed to such a system along with a detailed provider request. The system is then able to locate nearby providers that match said detailed provider request. Next, the nearby providers are prioritized according to a predetermined criteria, such as by distance, travel time, sponsorship or other possible criteria. The prioritized listing of nearby providers is then sent to the consumer. The consumer may then select a provider, whereupon the system, would return detailed information on the provider to the consumer. Additionally, the system may also respond with directions from the consumer's location to the selected provider.

Abstract: An adaptive digital filter is provided to obtain improved measurement accuracy in an electronic instrument which has a front-end circuit for coupling to an input signal to be measured. An analog to digital converter converts the input signal received through the front-end circuit into a stream of measurement values during the measurement phase. The stream of measurement values are then provided to the adaptive digital filter which mathematically operates on them to remove the frequency response effects of the front-end circuit in a process of convolution in the time domain using a set of digital filter values obtained during the calibration phase. Because the frequency response requirements of the front-end circuit have been eased with the addition of the adaptive digital filter, a simpler front-end circuit with fewer components and with no need for manual adjustment may be employed in electronic instruments.
