Abstract: Remote telemetry control in the testing of multiple projectiles such as rets, simultaneously fired, in an environment requiring extremely low power dissipation in the inactive state and experiencing extremely high-G accelerations during launch. On-board battery charging, battery and telemeter conditioning and telemeter control are remotely effected in a highly reliable manner through interfacing a portion of which is on board each projectile and another portion of which is remote from the projectiles and also remotely controlled for safety reasons. The aforementioned on-board functions are prioritized to accomplish first the charging and conditioning requirements, whereby telemeter activation during same is prevented, and the control signals governing charging, conditioning and telemeter operation are electronically isolated to prevent spurious activation. Electronic switching circuitry is incorporated to protectively ensure deactivation of the telemeter during higher priority operations.

Abstract: Disclosed is a recorder/editor apparatus for recording and editing digital audio data. A single digital signal processor (DSP) is used to control processing of digital audio data which corresponds to up to eight simultaneous audio channels. A plurality of buffers and a direct memory access controller (DMA) are provided such that the digital audio data may be recorded and played back from a magneto optical (MO) disk drive via a SCSI.
