Abstract: A network in which an incoming word of 4 bytes and 4 parity bits is split into an address pointer and Tag address data into a Tag RAM storing two bytes which do not align with the incoming bytes and which leave a 2-bit (x,y,) crossed field. A programmable array logic Control PAL places correct parity values into a Parity RAM for the 2 stored bytes and later recreates the original word of 4 bytes and parity bits by using a flip-bit value (SPX) which simplifies the regeneration of correct parity values.

Abstract: The present invention relates to an adaptive airflow control system for positioning damper systems or controlling air units utilized in an environment control system. The system is based on a conservative, fixed-gain, proportional-only feedback design to guarantee stable operation given the nonlinear behavior of flow through a valve or damper. A time-dependent deadzone of nonlinearity is used to reject measurement noise. Such a system allows a person to adjust the performance of the system by selecting a parameter that affects the tradeoff between tracking capability and noise rejection.

Abstract: A Viterbi decoder for recovering the original bit data stream that was convolutionally encoded as a code symbol stream in a Code Division Multiple Access (CDMA) mobile communication system. The decoder simultaneously decodes at the several data rates associated with certain multirate vocoders. The decoder can decode at an unknown data rate in either continuous or framed packet modes. It accomplishes this by simultaneously decoding at multiple rates and by creating one or more data quality metrics for each decoded data packet. Special input and output buffering is provided to isolate the decoder from system timing constraints. The input buffer includes selection and accumulation logic to organize code symbol data into the packet order for repeat mode or random burst mode at lower frame data rates.
