Abstract: An embodiment of the present invention provides a-method for performing a lateral flow assay. The method includes depositing a sample on a test strip at an application region, detecting a first detection signal arising from the test strip in the first detection zone, and generating a baseline for the first measurement zone by interpolating between values of the detection signal outside of the first measurement zone and inside of the first detection zone. The method may include locating a beginning boundary and an ending boundary for the first measurement zone on the test strip. Additional detection zones having measurement zones may also be incorporated with the embodiment.

Abstract: The invention provides a process and apparatus for the separation of nitrogen from a gaseous feed comprising a mixture of hydrocarbons and nitrogen gas, the process comprising the steps of: (i) cooling and at least partially condensing the gaseous feed; (ii) feeding the cooled and at least partially condensed feed from step (i) to a first fractionation to produce an overhead vapour stream having an enriched nitrogen content and a condensed product having a reduced nitrogen content which is subjected to a second fractionation, which comprises reboil, at a lower pressure than the first fractionation; (iii) partially condensing the overhead vapour stream, and separating to provide a liquid stream, which is used to provide reflux to the first fractionation, and a separated vapour stream, which is condensed to provide reflux to the second fractionation; and (iv) sub-cooling the condensed product of the first fractionation and dividing the resulting sub-cooled product into at least two streams: a first stream being

Abstract: A power tool control system includes a non-contact measurement and alignment device operative with the power tool and enabled to establish various readings, such as power tool settings. A graphical user interface communicatively coupled with the non-contact measurement and alignment device enables user control over and display of the readings from the non-contact measurement and alignment device. Related table saw assemblies are disclosed in which, for example, a bevel angle of a saw blade may be adjusted.

Abstract: A blade clamp assembly for retaining a rotary blade on the arbor of a rotary tool includes a blade washer for engaging the blade to hold the blade on the arbor and a clamp assembly threaded into the arbor to clamp the blade washer against the blade. The clamp assembly includes a planetary gear system for transmitting torque applied to the clamp assembly to the blade washer, wherein the planetary gear system multiplies the torque transmitted to the blade washer so that the torque transmitted to the blade washer is greater than the torque applied to the clamp assembly.

Abstract: A power tool may include a housing that supports an electrical circuit. The electrical circuit may include at least two terminal sets that are arranged in parallel to each other. The at least two terminal sets may include a first terminal set configured for engagement along a first axis to a battery pack having a first configuration and a second terminal set configured for engagement along a second axis to a battery pack having a second, different configuration. A battery charger may include a housing, and an interface that is electrically and mechanically compatible with at least two battery packs having different configurations and battery cell chemistries.

Abstract: A method of making a wear and fatigue resistant component of a power tool (e.g., a clutch) includes providing a quantity of base steel and a quantity of alloying elements to be added to the base steel to form a desired alloyed grade of steel. The base steel and alloying elements are combined and melted to produce a molten alloyed steel (e.g., SAE 9310 or AISI M2). The molten alloyed steel is cast using a near-net-shape investment casting process to form a component of a power tool. An edge of the component is pre-radiused. and the component is case hardened after the edge of the component has been pre-radiused. In one implementation, the component is a clutch that has a lifespan of at least twice a lifespan of a second clutch that has not been pre-radiused prior to case hardening.

Abstract: An adjustable reciprocating saw has the ability to adjust the orientation of the saw blade in relation to the rest of the tool. The saw blade can pivot about two transverse axes, one parallel with and one perpendicular to the reciprocating motion axis of the saw blade. The portions of the saw's housing which rotate relative to one another are attached with a rotating joint comprising a pin and groove design. Rotation locks selectively prevent rotation of the saw blade about each axis. The rotation locks can be released through simply depressing buttons on the saw. A rear internal bearing increases the durability and decreases the size of the saw. A keyless adjustable shoe is mounted to the saw.
