摘要:
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.

Amperage control of a power tool motor is provided by pulse width modulation of current from a power supply. The pulse width modulation may be varied according to the determined motor current and measured power supply voltage. The power supply preferably includes a battery, such a lithium ion or nickel cadmium.

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.

An adjustable angle magazine for a nail gun includes a pick-off pivot assembly. The pick-off pivot assembly pivotally couples the adjustable angle magazine to an adjustable angle nose casting assembly of the nail gun. Further, the pick-off pivot assembly increases the instances that a nail loaded into to the adjustable angle magazine is presented under a driver blade of the nail gun in a correct position.

A blade clamp assembly for retaining a rotary blade on the arbor of a rotary tool comprises 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.

A personalized combo kit of tools and accessories is assembled by the customer using a personalization system. A plurality of tools and accessories are provided to a customer for selection. The customer is enabled to select at least two items from the plurality and the selected items are offered to the customer at a discount price. The personalization system performs a compatibility check to determine that the tool components selected are compatible and thus eligible for inclusion as part of the combo kit. The personalization system assists in determining the offered price based on compatibility checking results.

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.
