1978 to 1986: Multichannel, Temporally-Interlaced, Pulsatile Speech Processors


  1. May 1985: UCSF (Lindsay Vurek) finished the implementation of a CIS proceesor but did NOT test it on a patient: It was capable of stimulating each of its 4 channels at a rate of 610 PPS -- for a combined rate of 2440 PPS.

  2. June-July 1985: At UCSF, RTI tested a CIS processor, it was a CIS processor except that its pulse-rate was "much too low" (only 313 PPS/channel for the 2 'peak-picked' channels out of 6).
