Abstract: A separation device assembly with efficiency that allows for multi-fault-tolerance. The separation device assembly comprising an inflation device that applies force to a shear plate assembly which in turn applies focused force to a frangible portion which has a groove or stress riser to facilitate fracturing. The assembly further comprising a means for limiting excess movement after fracture so that residual energy from the inflation device is applied to non-fractured portions of the assembly.

Abstract: An improved separation system comprising an inflation device which applies force directly to the frangible portions without the efficiency of shear plates. The assembly further comprising a means for limiting excess movement after fracture so that residual energy from the inflation device is applied to non-fractured portions of the assembly.

Abstract: A separation device assembly with efficiency that allows for multi-fault-tolerance. The separation device assembly comprising an inflation device that applies force to a shear plate assembly. The shear plate assembly focuses force in the optimal leg locations for efficient shearing of the frangible portions. The separation device assembly further comprising a means for limiting excess movement after fracture so that residual energy from the inflation device is applied to non-fractured portions of the assembly.

Abstract: A separation device assembly with efficiency that allows for multi-fault-tolerance. The separation device assembly comprising an inflation device that applies force to a shear plate assembly which in-turn applies focused force to a frangible portion. The assembly further comprising a set of upper and lower compressive load bearing elements which are configured as a stopping means. The limitation of excess movement after fracture allows residual energy from the inflation device to be applied to non-fractured portions of the assembly.

Abstract: The present invention is concerned with the field of Photonic Doppler Velocimetry (PDV), specifically a new method of handling laser light in order to record the velocity history of a moving surface. Send and receive paths are separated to produce a high optical signal to noise ratio (S/N). For non-mirror like (non-specular) surfaces, designs which optimize the S/N for a send path compete with those that optimize the S/N for a receive path. A small solid angle for the send optics minimizes noise through laser stabilization. A large solid angle for receive optics maximizes the signal. When these separate optimized designs are combined in a probe, the S/N of overall system is greatly increased.
