Abstract: The present disclosure provides methods of polynucleotide synthesis and compounds, compositions useful for synthesis of polynucleotides. The chemical compounds include nucleotides and their analogs that are attached to polymerase though a cleavable linker comprising an enzymatically cleavable amino acid ester.

Abstract: A medical device for treating shoulder dystocia having a first arm having a proximal portion, a distal portion and a first curved surface, a second arm having a proximal portion, a distal portion and a second curved surface and a shoulder engagement section positioned at least between the distal portion of the first and second arms and connecting the first and second arms. The engagement section is configured to contact and press down on the baby to reposition the baby.

Abstract: Apparatuses, systems, and methods dynamically model intrinsic parameters of a camera. Methods include: collecting, using a camera having a focus motor, calibration data at a series of discrete focus motor positions; generating, from the calibration data, a set of constant point intrinsic parameters; determining, from the set of constant point intrinsic parameters, a subset of intrinsic parameters to model dynamically; performing, for each intrinsic parameter of the subset of intrinsic parameters, a fit of the point intrinsic parameter values against focus motor positions; generating a model of the intrinsic parameters for the camera based, at least in part, on the fit of the point intrinsic parameter values against the focus motor positions; and determining a position of a fiducial marker within a field of view of the camera based, at least in part, on the model of the intrinsic parameters for the camera.

Abstract: A light fixture that can be built upon itself to scale up or down the lumen output. More specifically, embodiments of the light fixture include an electronic housing flanked on each side with one or more light modules. The fixture can be tailored to the light needs of particular applications by adding or removing light modules from the fixture.

Abstract: Embodiments relate to systems and methods for securing one or more printed circuit boards to a substrate. The substrate may include retention tabs that form a receiving slot that receives an edge of the printed circuit board. The retention tabs and printed circuit board may have corresponding engaging features designed to retain the printed circuit board within the receiving slot and that, in some embodiments, can permit slight movement of the printed circuit board within the receiving slot to accommodate any thermal expansion of the board during use.

Abstract: A deposition system includes a process tube aligned vertically with a substrate holder therein positioned horizontally and perpendicular to a vertical tube axis. Through a bottom or top flange a first gas line connector is for injecting a first gas and a reactant gas connector is for injecting at a reactant gas. A feed line is coupled between the reactant gas connector and a reactant gas distributor having apertures for flowing the reactant gas towards a substrate. A vapor generating showerhead includes a gas distribution plate having flow distributing apertures on a precursor boat having gas inlets fluidically coupled to precursor holder trenches that hold a vapor generating material. The gas inlets have a flow path for flowing the first gas over the vapor generating material for generating a reactant vapor that flows out of the flow distributing aperture toward the substrate.

Abstract: Described are embodiments of driver brackets having dividers that separate low voltage wires from high voltage wires within a driver enclosure so as to reduce the risk of high and low voltage wires coming into contact within the driver enclosure. Also described are embodiments of driver brackets that support a driver entirely on one side of the driver bracket.
