The uses of the disclosed copper-cysteamine (Cu-Cy) complex for methods for treating Gram-positive and Gram-negative infections in subjects and for disinfecting a surface are disclosed. In addition, the disclosed Cy-Cy nanoparticles provide Fenton-like reactions in vivo, in vitro and ex vivo.

A wireless communication system has a protocol enabling synchronous code division multiple access (CDMA) communication on a time division duplex (TDD) frequency, and provides for a smart antenna system as an integral component of the system. The protocol has downlink time slots (DTS) which provide for synchronization and paging of all remote terminals from a base station on a omnidirectional code channel and while providing for traffic signals on directional traffic channels. The protocol has uplink time slots (DTS) which enable rapid link requests by remote terminals, as well as enabling improved spacial estimation, synchronization and power control of remote terminals by the base station.

A parallel IIR filter (100) has low quantization effects and includes a multiplier (103) which multiplies a digital input signal by a constant, and an arbitrary number of biquad filters (104, 105). Outputs of the multiplier (103) and each biquad filter (104, 105) are summed together in a summing device (106) to provide an output signal of the IIR filter (100). The IIR filter (100) first expresses its transfer function as a cascade form transfer function, and then calculates the constant as a product of a constant term of each cascade form biquad term. The IIR filter (100) partially decomposes the cascade form transfer function to provide first order terms, and calculates numerator coefficients of the first-order terms. Pairs of decomposed terms are recombined to provide a parallel form transfer function, from which parallel form coefficients are taken and applied to the biquad filters (104, 105).
