Abstract: The present disclosure provides a surgical shunt assembly tool that provides a more efficacious grip on the catheter tubes and prevent the tip of the catheter from buckling while the catheter is pushed onto the tip of the valve during installation of shunts during CSF shunt surgery. The tool includes standard handles such as used in a shodded mosquito tool having a clamping jaw integrated into the distal end section of the handle. The distal jaw includes two forcep jaw sections each having a proximal end integrally formed with a distal end of a distal end arm section of one of the two handle arms, and a distal end section extending away from the distal end arm section. The distal end sections of the forcep jaw sections are cylindrically shaped such that when the forcep jaw is closed by bringing the two forcep jaw sections together, a cylinder is formed having a diameter substantially equal to a diameter of a catheter tube to be attached to a shunt valve tip.

The kit includes a deformable vinyl substrate, an underlayment layer configured to allow the deformable vinyl substrate to frictionally engage a stabilizing surface, at least one writing implement, and an eraser component configured to remove one or more markings generated by the at least one writing implement. The deformable vinyl substrate further includes an extended configuration to support marking/drawing on the deformable vinyl substrate and a storage configuration to support stowing of the kit.

Abstract: A hypernym of a word in utterance data may be probabilistically determined. The utterance data may correspond to a spoken query or command. A redacted utterance may be derived by replacing the word with the hypernym. The hypernym may be determined by applying noise to a position in a hierarchical embedding that corresponds to the word. The word may be identified as being potentially sensitive. The hierarchical embedding may be a Hyperbolic embedding that may indicate hierarchical relationships between individual words of a corpus of words, such as “red” is a “color” or “Austin” is in “Texas.” Noise may be applied by obtaining a first value in Euclidean space based on a second value in Hyperbolic space, and obtaining a third value in Hyperbolic space based on the first value in Euclidean space. The second value in Hyperbolic space may correspond to the word.

Abstract: Systems, methods, and computer-readable media are disclosed for providing privacy and intent preserving redactions of text derived from utterance data. Certain embodiments provide new techniques for using MadLib-style replacements to replace one or more terms or phrases in a text string. Example methods may include receiving utterance data and determining a public portion and a private portion of the utterance data. Certain methods include determining a cluster of candidates having a same semantic context as the private portion and identifying from within the cluster of candidates a first candidate. Certain methods include determining a redacted utterance comprising the public portion of the utterance and the first candidate. Certain methods include providing the redacted utterance to downstream systems and processes.

Abstract: An auxiliary photographic lens and lens holder bracket for an existing portable cellular phone having a camera function therein. The square U-shaped lens holder bracket straddles the body of the cellular phone positioning the auxiliary lens over the built-in camera lens of the existing cellular telephone. The lens cylinder has a threaded end which screws into a threaded opening in the front of the bracket and against the cell phone case around the built-in lens to secure the lens to the cell phone. The lens holder alternately serves as a protective storage device for the lens when it is not in use with the lens cylinder screwed into the cross piece of the bracket. The lens may be a telephoto lens, a wide angle lens, a filter, or alternately a zoom or adjustable lens.

Abstract: The present invention provides a method to detect and generate ultrasonic displacements at a remote target for ultrasonic inspection. This method involves generating an ultrasonic wave at a first location on an upper surface of the remote target. This ultrasonic wave is reflected from interior surfaces within the remote target wherein the reflected ultrasonic wave produces ultrasonic displacement at a second location on the upper surface of the remote target. A detection laser beam is generated and directed to the second location on the upper surface of the remote target. Here, the detection laser beam is scattered by the ultrasonic displacements to produce phase-modulated light. This phase-modulated light is collected and processed to obtain data representative of the ultrasonic surface displacements. Further, these ultrasonic displacements, when processed, will yield inspection information associated with the interior of the remote target.

Abstract: The present invention provides a compact optical probe assembly that measures ultrasound in materials. The probe uses angle-terminated optical fiber to direct illumination laser light at the surface of a remote target. Ultrasonic displacements at the surface scatter the illumination laser light. Angle-terminated optical fibers collect phase modulated light and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic surface displacements. The probe may also incorporate angle-terminated optical fibers to direct generation laser light to the surface of a remote target to generate ultrasonic surface displacements. Optional shared beam forming element(s) may optically act on the illumination laser and collected phase modulated light.

Abstract: A system and method that replaces safety requirements of a laser detection system by shifting the wavelength of a detection laser. An optical wavelength converter that shifts the optical wavelength of a detection laser from a first wavelength within the Infrared “A” portion of the spectrum to a more eye-safe wavelength. The detection laser is directed to the surface of a remote target. Ultrasonic displacements at the surface scatter the filtered detection laser. Collection optics then gather phase modulated light scattered by the surface and direct the phase modulated light to an optical processor that produces a signal representative of the ultrasonic displacements. Signal processors then determine the internal structure of the remote target based on the signal.

Abstract: The present invention provides an optical filter assembly that reduces the phase and amplitude noise of a detection laser used to detect ultrasonic displacements. The filtered detection laser is directed to the surface of a remote target. Ultrasonic displacements at the surface scatter the filtered detection laser. Collection optics then gather phase modulated light scattered by the surface and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic displacements with an improved SNR. Additional processors may determine the structure of the remote target.

Abstract: An antenna that includes a housing having a plurality of walls forming an enclosure, a slot formed in a first wall of the housing, and, a folded cavity formed in a second wall of the housing opposite the first wall. The folded cavity is preferably a compound cavity that includes a first cavity portion and a second cavity portion joined around their entire respective peripheries by a fold or shelf. Any convenient RF transmission line, e.g., a waveguide or coaxial cables, can be used to inject RF energy into the folded cavity. In certain embodiments, both the width and length of the housing are each less than ½ of a free-space wavelength, and the antenna is capable of producing very accurate circular polarization and is capable of handling very high power levels, e.g., 10 kW, thereby making it suitable for high power applications which require extremely compact antenna elements, e.g., wide-scan phased array antennas.

Abstract: A common aperture reflector antenna and feed are provided for use in common aperture sensor systems. The feed includes an array of individual elements. The array elements are configured to increase the overall efficiency of a reflector antenna by flattening the aperture illumination, and also by nullifying the illumination within the centrally-blocked-portion of the reflector antenna surface. More specifically, the array elements are carefully configured with respect to spacing and excitation, for example, such that the array illuminates only the non-blocked portion of the main reflector. In addition, the array pattern is optimized such that the non-blocked portion of the reflector antenna is quasi-uniformly illuminated.
