A multichannel compensating audio system includes first and second compensation channels to psychoacoustically minimize deviations in a target response, to psychoacoustically move the physical position of a speaker and / or to psychoacoustically provide a substantially equal magnitude of sound from a plurality of speakers in a plurality of different listening positions. The first compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a first compensated audio signal from a first audio signal. The second compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a second compensated audio signal from a second audio signal. A first summing circuit is configured to receive at least the first audio signal and the second compensated audio signal and generate a first output signal for provision to a first speaker. A second summing circuit is configured to receive the second audio signal and the first compensated audio signal and generate a second output signal for provision to a second speaker. The first and second output signals may be output by the first and second speakers into a listening space and are acoustically perceived by a listener.

A system may include a target implantable medical device (IMD) and an external device configured to selectively communicate with the target IMD. The external device may include a communication module configured to communicate with the target IMD, a response analysis module configured to receive and analyze a target response signal from the target IMD and other response signals from other IMDS, and a power adjustment module configured to receive one or more power-adjustment request signals from the response analysis module. The power adjustment module is configured to adaptively adjust a power of a transmission request over a first frequency band based on the one or more power-adjustment request signals until the response analysis module receives only the target response signal from the target IMD.

A FM CW cable guided radar for the detection and location of outdoor perimeter intruders. Helically wound outer conductors on coaxial transmit and receive transmission lines provide a slow wave structure to support the propagation of external electromagnetic fields. The two leaky coaxial lines are enclosed in an extruded plastic jacket with the outer conductors in continuous electrical contact along the length of the cable. A chirp frequency modulation provides a continuous target response having a baseband frequency that is proportional to the distance along the length of the cable. After location determination, the amplitude of the response is compared to a location specific threshold to determine if an intruder is present.

The present invention provides methods and apparatuses that can improve measurement accuracy in interferometers. The invention provides methods for determining digital compensation filters that measure a frequency response or responses to be compensated, and then determining a filter target response from the inverse of the frequency response or responses. A digital compensation filter can be determined from the filter target response using a discrete sum of cosines with a phase argument. The invention also allows other desired filter responses to be integrated into the filter target response before determining the digital compensation filter.

A cyclic redundancy check (CRC) mechanism for the extensions (PCI-X) to the Peripheral Component Interconnect (PCI) bus system used in computer systems is fully backward compatible with the full PCI-X protocol. CRC check-bits are inserted to provide error detection capability for the header address and attribute phases, and for burst and DWORD transaction data phases. The CRC check-bits are inserted into unused attribute or clock (or target response) phases, or into reserved or reserved drive high portions (bits) of the address / data (AD), command / byte enable (C / BE#), or into the parity lanes of the PCI-X phases.
