Abstract: A passive microscopic flow sensor includes a three-dimensional microscopic optical structure formed on a cleaved tip of an optical fiber. The three-dimensional microscopic optical structure includes a post attached off-center to and extending longitudinally from the cleaved tip of the optical fiber. A rotor of the three-dimensional microscopic optical structure is received for rotation on the post. The rotor has more than one blade. Each blade has a reflective undersurface that reflects a light signal back through the optical fiber when center aligned with the optical fiber, the blades of the rotor shaped to rotate at a rate related to a flow rate.

Abstract: A system, apparatus, and method include a first display device having a first set of pixels adapted to output light; a second display device having a second set of pixels adapted to output light; a first transparent plate spaced apart from each of the first display device and the second display device. The first transparent plate includes a first set of photonic crystal structures arranged in a first direction and adapted to deviate a first path of the light transmitted from the first and second set of pixels at a first angle. A second transparent plate is spaced apart from the first transparent plate and includes a second set of photonic crystal structures arranged in a second direction different from the first direction and adapted to deviate a second path of the light transmitted through the first transparent plate at a second angle to create a third path of light.

Abstract: A transmission filter apparatus is provided that includes: (i) a substrate to serve as a foundation for the apparatus; (ii) a layer containing resonant dielectric cavities separated by conductive regions. The dimensions and design of the dielectric cavities, thickness of the layer, and substrate, dielectric and conductive materials are chosen to achieve resonant transmission of selected wavelengths. In a particular one or more embodiments, the layer is one dimensional, i.e. you have dielectric cavities along one axis in the plane that are comparatively infinity long in the parallel plane. In a particular one or more embodiments, the layer is two dimensional, i.e. you have dielectric cavities along both axis in the plane. The dimensions in each plane may or may not be equal. In a specific one or more embodiments, the dielectric cavities are terminated on the top and/or bottom by thin metal films with small apertures or tapers.

Abstract: The present disclosure addresses a novel feedback design methodology to meet the emerging frontiers of beamforming radio frequency (RF) technology in the areas of machine learning and surveillance. The feasibility of developing adaptive waveform modulation schemes for spectrum management in radars via orthogonal wavelet concepts. With the increasing prevalence of RF spectrum bandwidth limitations, this approach of adaptive feedback waveforms addresses advanced signal processing beamforming technique for phase array RF improving overall sensing performance. The adaptive illumination waveform algorithms for enhancing detection, discrimination, and tracking is motivated from the analogy drawn between the cellular wireless communication systems and the general multi-static radar automotive systems. The present innovation has developed signal processing schemes of adaptive illumination waveforms for enhancing RF detection performance and have developed a unified system architecture of the adaptive radar waveform design for various scenarios including multi-static radars and multiple targets.

Abstract: An adaptive force vehicle airbag (AFVA) system includes airbag(s) stowed in a compressed state within an interior of a vehicle. An impact sensor detects a change in motion of the vehicle indicative of a collision. Selectable force gas generator(s) (SFGGs) gas-generating propellant cells that are individually fired. The SFGGs have conduit(s) that receive gas from fired gas-generating propellant cells and direct the gas to inflate at least one of the airbag(s). A controller is communicatively coupled to the inflation initiating component and the gas-generating propellant cells of the SFGGs. The controller enables the AFVA system to: (i) receive an inflation signal from the impact sensor; and (ii) fire a selected number of the gas-generating propellant cells to at least partially inflate the at least one airbag.

Abstract: A material testing system that uses at least one hydraulic grip is improved with cable clips that are attachable to a respective lateral side of each hydraulic grip wedge. Each cable clip has another end that extends to engage a cable(s) extending from a corresponding wedge retention spring hole. The cable(s) enable manual extension of a wedge retention spring for engagement and disengagement from the hydraulic grip wedge. The cable clip maintains the cable in a noninterfering position during operational use of the material testing system.

Abstract: A fiber laser system includes a high power pump laser, an optical fiber that is aligned to receive output from the high power pump laser. The fiber laser system includes a first pair of orthogonally opposed, periodic electrode structures longitudinally aligned on opposite first and second sides of the optical fiber. The fiber laser system includes a controller that is communicatively coupled to the first pair of periodic electrode structures. The controller performs variable period poling of the first pair of periodic electrode structures to achieve quasi-phase matching (QPM).

Abstract: A Solid Instrumented Spherical Blast Impulse Recording Device (SISBIRD) includes a spherical housing formed of material that is resistant to an explosive blast wave from a test weapon. A test payload bore shaft is accessible through an opening in the spherical housing. A door is fastened over the opening in the spherical housing. A test data module is received in the test payload bore shaft. The test data module includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller. The controller is communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record, in the memory, acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave.
