Abstract: Systems, devices and methods may provide for facilitating a direct fund transfer from an aid organization to a service provider. The system may maintain an aid organization account associated with the aid organization, maintain a beneficiary account associated with each beneficiary enrolled with the aid organization, and maintain a service provider account associated with each service provider. Each beneficiary account may be configured as a virtual stored-value account for storing value corresponding to funds from the aid organization. The system may also receive transaction data corresponding to a transaction between a beneficiary and a service provider including identifier information, debit a value corresponding to the transaction amount from the beneficiary account that is mapped to a beneficiary identifier, and transfer funds corresponding to the transaction amount from the aid organization account directly to a service provider account that is mapped to a service provider identifier.

Abstract: A technique for reflectometry testing of a signal path is disclosed. The technique includes injecting a test signal based on a probe pseudo-noise sequence into the signal path and obtaining a response signal. A sliding reference pseudo-noise sequence is correlated against the response signal. Both the probe sequence and the reference sequence are generated at a chip rate. The correlation is obtained for integer chip time delays, and sub-chip resolution of a peak correlation delay is estimated from at least two samples of the correlation.

Abstract: A multiplierless IIR filter incorporates power-of-two coefficients to perform shift operations to reduce space and increase speed. To optimize performance, a genetic algorithm generates the power-of-two coefficients. The filter architecture includes shift registers to receive input samples and previous outputs. A shifter stage is employed to perform shift operations for the input samples and previous outputs based on corresponding power-of-two coefficients. Products are added by parallelism and sequential pipelining to produce an output.
