Abstract: A low cost dedicated hardware arrangement for reconstructing successive data frames from for example a commutated telemetry-communicated serial stream of digital and analog data, data which may be of unspecified words per data frame content. Encoding and detection of a word length synchronization signal within each data frame of the stream in accordance with the protocol of a commercially available telemetry encoder/transmitter apparatus is contemplated in the disclosed embodiment of the invention. The disclosed system is tailored for minimum communication protocol flexibility along with minimum fabrication and utilized space costs. Use in the spread spectrum telemetry environment and fabrication using dedicated logic array techniques are also contemplated. Military and non-military uses of the system are feasible including uses in medical environments.

Abstract: The system is a remotely operated, autonomous multi-channel time history recording device which uses digital and computer technologies to detect, record and display the results of tests that are time varying dependent. It is particularly suited to monitoring the effects of exploding warheads. By placing a series of piezoelectric detectors in an exploding shock wave field, it is possible to ascertain the wavefront propagation. A dynamic peak detector is used is used with each piezoelectric detector to detect the exact peak of the unknown pulse which peak defines the "time-of-arrival" of the pulse. By controlling the system with a computer program it is possible to display the complete time history of the propagating shock wave. When the exploding device is detonated a counter increments in 100 ns steps with its output on a timing bus.
