Shockwave suppression is accomplished by channeling a shockwave from a shockwave source, such as a firearm, into a suppression device along a propagation path, and within the suppression device, deflecting a portion of the shockwave away from the firing axis, and channeling the deflected portion through a feedback path and back to a region behind the deflected shockwave. The suppression device can be formed from one more chambers arranged within an outer wall and including baffles and inner wall sections.

Suppression device and related methods

A data and clock recovery arrangement, for a high speed fiber optic digital communication system in which a serial digital bit stream is pre-scramble encoded by interleaving complementary pairs of overhead bits between successive groups of data bits, and then scrambled and transmitted to a receive site, comprises a data rate independent variable bit rate synchronizer, a descrambler and a decoder. The data rate independent variable bit synchronizer processes the received scrambled and encoded digital bit stream to derive a variable data rate synchronization clock signal. The synchronizer is capable of accepting any data rate within the operational data clock signal range of the system, and automatically tunes itself to the data clock signal embedded in the received scrambled and encoded serial data stream, so as to output respective scrambled and encoded serial data and clock signals. The descrambler descrambles the scrambled and encoded serial digital bit stream using the variable data rate synchronization clock signal, and the decoder decodes the descrambled serial digital bit stream to extract groups of data bits exclusive of the complementary pairs of overhead bits and to derive an output clock signal having a frequency coincident with the data rate of the data bits.
