Abstract: A control system for delivering energy waveform radiation to influence in vivo tissue is described. For the system, the energy waveform radiation is generated by a radiation unit and is directed along a pathway to the tissue and a registration unit is provided to identify a start place relative to the in vivo tissue. Also, a monitor is provided to compare the start place with a base reference to measure an error signal between the start place and base reference. With this measured error signal, a controller operates the radiation unit using input from the monitor to effectively attain and maintain a zero error signal. More specifically, the controller can provide operational parameter inputs to the radiation unit for configuring the waveform radiation including a radiation frequency, f, and a volume intensity level, v, for the radiation and an exposure time interval, ti.

Abstract: An ultrasonic inspection technique may be used to inspect quality of a bond between thermal protection system (TPS) material and a composite. The technique may include a highly damped transducer emitting an incident wave, which may traverse through thermal protection system (TPS) material and to a back wall of a composite. The incident wave may be of a low frequency signal, and may return a bondline echo and a backwall echo. The bondline echo is returned when the incident wave reaches a bondline and the backwall echo is returned when the incident wave reaches the backwall of the composite. The bondline echo and the backwall echo may be used to generate a waveform to assess the bond quality, revealing possible unbonds or kissing unbonds.

A first slot in the wall is disposed along a radial arc of the tube. A second slot in the wall extends from an end of the first slot at an angle acute to the first slot. The rod extends through the wall, and rotates the cam tube while moving linearly along the cam tube in the second slot and while moving in an arc in the first slot.

Abstract: A portable x-ray computed tomography (CT) system may utilize algebraic reconstruction techniques (ART) to produce 3D volume images from tens of shots or less. The system may be deployed as desired where x-ray source and detector positions are not known beforehand. A fast, accurate matrix may be formed relating voxels to detector pixels via a modified ray tracing algorithm, eliminating artifacts caused by approaches using rough approximations. Masking or recombination may be performed to remove detector pixels that are not part of a region of interest (ROI) or lump the pixels together as one unknown, significantly reducing matrix size, and hence, computation time. The positions and orientations of the x-ray source and detector may be treated as unknowns and refined to optimize a volume image metric. For example, the optimized metric could be image contrast, image sparsity, or total variation.

Abstract: A system and method for directing vibrational oscillating sonic waves toward a target tissue in the body of a person, to thereby influence a phenotypic differentiation of the target tissue at a cellular level, requires the use of an epidermal or implantable patch. Mounted on the patch is a sonic generator for generating sonic energy that entrains cellular functions of the target tissue for a desired phenotypic response. Also included is a unit for titrating the target tissue to monitor for changes in an expression level of the target tissue resulting from phenotypic differentiation.
