Abstract: A multi-legged equipment support, components thereof, and associated methods. The equipment support comprises a stand and an equipment holder. The stand includes a hub and multiple legs pivotable with respect to the hub. The legs are pivotable outward from stowed positions to preset operational pivoted positions. The user can select a preset operational pivoted position in which outward pivoting of a leg will stop based on moving an actuator between preset locations.

Abstract: An anti-cant indicator assembly, components thereof, and associated methods. The anti-cant indicator assembly indicates the orientation of a weapon with respect to vertical. The anti-cant indicator assembly includes a mount configured to mount to the weapon, a level including a vial containing a bubble and a pivot connection connecting the level to the mount. The pivot connection is configured to permit movement of the level with respect to the mount about the pivot connection between an operational position in which the bubble can be referenced by the user for indicating orientation of the weapon with respect to vertical, and a stowed position different from the operational position. The pivot connection can include a retainer configured to releasably retain the level in at least one of the operational position or the stowed position. The level can be selectively movable with respect to the mount to calibrate the anti-cant indicator.

Abstract: The present invention relates to a method for making a Pickering emulsion, the method comprising: exfoliating a non-silicate layered 3D material in a solvent to produce particles of a non-silicate unfunctionalised 2D material; forming a dispersion of the particles of the 2D material in a first liquid phase; adding a second liquid phase; and homogenising the dispersion of the 2D material in the first liquid phase with the second liquid phase to form a Pickering emulsion comprising the first liquid phase, the second liquid phase, and the particles of the 2D material.

Abstract: The present disclosure relates to compositions and methods for treating cancers. In particular, the present disclosure provides materials and methods for identifying mis-splicing-associated surface antigens (MASAs) generated by altered spliceosome proteins, as well as materials and methods for targeting cancerous tumors expressing MASAs.

Abstract: The invention relates to a material comprising oligoglycine tectomers and nanowires. This material is useful as an electrode, as a conductive and transparent hybrid material, and as a pH sensor, as well as in biomedical applications.

Abstract: Methods and apparatus for manufacturing a conductive thin film are provided. In one arrangement, compositions of nanowires having different mean aspect ratios are mixed together and applied as a layer on a substrate. In other arrangements a single composition of nanowires is processed in order to increase an aspect ratio variance and the processed composition is applied as a layer on a substrate. The layers thus applied provide an improved balance of electrical conductivity to transparency and are expected to provide improved isotropy in the inplane conductivity.

Abstract: A bone fixation screw includes a threaded screw shank and a screw head having upper and lower ends. The screw head lower end is secured to a proximal end of said screw shank. The screw head has substantially frustospherical shaped side surfaces and is split into segments at one of the ends. The head is radially expandable at the one end. An expansion screw is centrally received in the screw head. An interface between the expansion screw and the screw head forms a cam mechanism for expanding the screw head upon axial rotation of the expansion screw.

Abstract: A retractor for percutaneous surgery in a patient which includes an elongate retractor tube composed of circumferentially arranged elongate independent tube segments with proximal ends of the tube segments respectively hinged to a unitary collar whereby the distal ends of the tube segments may be outwardly expanded in umbrella fashion by outwardly pivoting the segments about their respective hinges for thereby retracting surrounding tissue. The distal end of the retractor tube is provided with a tapered distal end suitably dimensioned for insertion into a stab incision. An internally open expansion collet is coaxially received in the collar for adjustable coaxial advancement downwardly into the collar toward the retractor tube segments and fulcrum tabs protrude inwardly and upwardly towards the expansion collet from each tube segment adjacent a respective hinge.

Abstract: A bone plate is provided for fixation of spaced vertebra. The bone plate has at least one through passage for securing the plate to bone with a bone fixation screw. The threaded shaft of a bone fixation screw is inserted through a bushing located in the through passage of the bone plate and the screw is thereby threadably secured to the underlying bone and the bushing is then compressed inward against the head of the screw with cams that are actuated by rotating the bushing in the through passage whereby the screw is locked relative to the bone plate. The bushing is not only compressed inwardly against the head of the screw but is also compressed downwardly by the cams into a seat to clamp separate elements of the bone plate together.

Abstract: A bone fixation assembly which includes a fixation plate having a through passage and a fastening screw having a threaded shaft for insertion through the passage and thereafter threadable insertion into underlying bone. The screw head has substantially frustospherical shaped side surfaces. A bushing is provided and has an annular cup shaped side wall defining an upwardly open interior bowl for receiving the screw head. The bushing has annularly spaced slots in its side wall which depend downwardly from its upper end for allowing inward compression of the side wall at the upper end. A centrally located screw shank passage is provided in the lower end of the bushing to prevent passage of the screw shank. The bushing bowl is further configured and dimensioned for polyaxial rotation of the screw head in the bowl and for preventing back out of the screw head when the side wall is compressed inwardly.

Abstract: Vertebra bodies in the human spine are stabilized through the use of minimally invasive surgery for the implantation of an elongate implant plate assembly having spaced first and second screw receiving socket elements which are configured for respective attachment to first and second spaced vertebra with the aid of bone fixation screws and these elements are slidably received with respect to each other for adjustably changing the distance between the screw receiving socket elements. A lock assembly is also provided for selectively locking the first and second screw receiving elements from further relative sliding.

Abstract: A cervical compression plate assembly having screw receiving elements at opposite ends that are configured for engaging bone fixation screws extending from respective vertebral elements. The assembly permits the distance between the screw receiving elements at opposite ends to be shortened but prevents the distance from increasing. A spring mechanism is housed within the plate assembly and is configured for continuously urging the screw receiving elements at opposite ends together for thereby providing continuous compressive loading on bone graft material disposed between the vertebral elements.

Abstract: A dosimetry probe for monitoring light irradiation dosages and for providing irradiance measurements to monitor the application of light during a phototherapy procedure. The dosimetry probe includes a light delivery optical fiber operable to transmit optical radiation to target tissue and a plurality of dosimetry optical fibers substantially coextensive with the light delivery optical fiber, the distal ends of each of the dosimetry optical fibers arranged at a different axial distance from the light delivery optical fiber to provide irradiance measurements at a number of different axial distances. The dosimetry probe may include a safety feedback optical fiber to monitor the intensity of the treatment light independent of the influence of the optical properties of the target tissue. The dosimetry probe may also include a source dosimetry optical fiber for carrying a modulated dosimetry light signal, which can be selectively detected by means of frequency lock-in technology.
