Patent ID: 7102349

Claim:
An NMR apparatus for study of the content of a sample volume, comprising: a polarizing magnet for establishing a preferred direction for nuclear spins, a source of RF energy controllable for selected phase, amplitude and frequency, an RF controller comprising a clock device for synchronous operation, comprising a processor device for initializing RF operational parameters for defining each said state to default values thereof, prescribing a progression of states at subsequent adjacent discrete times, comprising assigning a duration to each state, characterizing each state by the changes in value from the preceding state of one or more said parameters, transferring only said changed values of said RF parameters to a corresponding plurality of latched data registers, said latched registers corresponding to operand parameters, and also transferring content of said latched registers to a respective computational cell and computing the resultant of said operand parameters and retaining same in a latched resultant register, communicating the parameters retained from each said latched register and each said resultant register and corresponding duration to an asynchronous-to-synchronous buffer, presenting said parameters and resultants to an output in synchronous relation to said clocking device, and maintaining said output for said corresponding duration, and causing said output to operate said source of RF energy in accord with said output.
