Abstract: A network-based navigation system includes a user interface and a computer server system that can access a map database, an actual imagery database and an advertisement database in order to provide visual route guidance information having virtual drive-thru advertisements integrated with actual imagery from along a physical route. The user interface permits a user to submit a request for navigation information, receive visual route guidance information in response to the request and initiate a drive-thru presentation of at least a portion of a route. The computer server determines at least one route from the map database based on the request from the user and provides route guidance information to the user interface in response.

Abstract: A low spur phase-locked loop (PLL) architecture is provided. A frequency-synthesizing PLL that includes a differential Kvco gain linearization circuit with adjustable DC offset is used to reduce clock jitter. The free-running oscillation frequency of the VCO of the PLL is centered near the desired frequency using programmable loads to minimize the required control voltage range. The PLL uses a differential architecture that includes a charge pump that compensates for variations in Kvco and a LC tank oscillator with differential controlled varactor. The differential PLL architecture demonstrates that the reference spur can be well controlled to below ?80 dBc.

Abstract: Combined echo and crosstalk cancellation is provided. Frequency domain adaptive filters are used to remove or reduce the effects of echo and crosstalk for a multi-channel and full-duplex communications system. Data from each transmit channel is buffered and converted to the frequency domain. The frequency domain data is multiplied by crosstalk coefficients to obtain a frequency domain correction signal for each channel. Adaptation of the crosstalk coefficients is based on correlations between the error signals and the data from each of the transmit channels. A single frequency domain transform engine, such as a Fast Fourier Transform engine, is employed for all calculations to save power and area.

Abstract: Automated methods and systems are disclosed for persistently facilitating the timely gathering, monitoring, distribution and delivery of information related to medical care where such may include: (1) finding a communications channel for effectively attempting a message delivery to a specific target person at a specified time; (2) adaptively finding a targeted recipient even if the latter is highly mobile and/or has travel patterns or communications-channel preferences that change over time; (3) verifying that a targeted recipient has actually received an attempted delivery within an applicable time limit; (4) automatically recognizing that an urgent message delivery-attempt was not timely completed and adaptively alerting responsible entities of the in completion; and (5) automatically recognizing that an urgent change or non change of condition has occurred by virtue of information gathered during an automated or manually-conducted Interview where physician expected positive progress prior to Interview and

Abstract: A smart card is disclosed which receives, decodes, and stores encoded data signals comprising redeemable coupons. Encoded data coupons are embedded within television segments and are transmit along with the normal television segments. The smart card receives the luminescent signals which comprise the encoded data coupons directly from the display. The smart card decodes the data coupons. The coupon is then stored within the smart card for future use. The smart card is equipped with an LCD which enables UPC codes corresponding to each of the stored coupons to be utilized. A scanner reads the UPC codes at the coupon redemption site. Once redeemed, the coupon is erased from the memory in the smart cad. Advantageously, all of the functions including receiving, decoding, and storing the data signals are performed by the smart card.
