Abstract: A cordless router motor unit has a metal barrel and a plastic battery housing. A DC motor is housed inside of the barrel and drives an output shaft and up to a ½″ collet chuck. The battery housing holds a power switch and is fastened to the barrel. A battery is releasably attached to the battery housing through a sliding engagement in a direction normal to the longitudinal axis of the motor unit. When the battery is in its locked position relative to the battery housing, the center of gravity of the battery is balanced over the output shaft. The power switch is positioned radially from the DC motor and below the battery so that the router motor unit has a low center of gravity. The battery provides at least 18V and the maximum power output of the DC motor is at least ⅝ hp. The barrel can be sized to engage with a router base which also engages with a corded router motor unit.

Abstract: A portable pneumatic fastening tool has an onboard compressor assembly to alleviate the need for an external air compressor. The onboard compressor assembly includes a motor and a compressor mounted to the tool body. The motor can be powered by a detachable battery mounted to a cover for covering the onboard compressor assembly. A portable pneumatic fastening tool may also be powered by a portable compressor assembly which can be borne by the user.

Abstract: The present invention relates primarily to the field of water purification. Expanded inclusive methods for purifying polar solvents are disclosed. Said expanded methods include unique means for removing life forms, such as microorganisms, from polar solvents. The process is useful in the rapid and efficient removal of suspended living and dead microorganisms, or other biological material from polar solvents.

Abstract: Systems and methods for medical diagnosis or risk assessment for a patient are provided. These systems and methods are designed to be employed at the point of care, such as in emergency rooms and operating rooms, or in any situation in which a rapid and accurate result is desired. The systems and methods process patient data, particularly data from point of care diagnostic tests or assays, including immunoassays, electrocardiograms, X-rays and other such tests, and provide an indication of a medical condition or risk or absence thereof. The systems include an instrument for reading or evaluating the test data and software for converting the data into diagnostic or risk assessment information.

Abstract: In a vehicle having an engine and an ignition system, a sensing circuit is provided for sensing the ignition voltage and providing this sensed signal to various operating modules of the vehicle. The sensing circuit includes a diode/resistor filter that provides a filtered voltage signal at a first output node. A compensation circuit is provided that compensates voltage errors introduced by the filter circuit. The compensation circuit includes a second diode that has substantially identical electrical performance characteristics as the first diode, and that is preferably mounted on a common substrate. A voltage signal at a second output node between the second diode and the filter circuit is indicative of the voltage drop across the second diode, which is further representative of the voltage error introduced by the filter circuit. In one embodiment, the operating module receiving the ignition voltage signal is configured to receive voltage signals at the first and second output nodes.

Abstract: A method and apparatus for three-dimensional coordinate determination in automotive crash repair and diagnostics and other uses provides location-defining means in the form of a pointer having an angularly displaceable end portion and corresponding angular displacement sensing means adapted to feed a signal to the data processing system to enable continuous monitoring of the instantaneous coordinates of the relevant portions of the pointer for mapping purposes whereby access to difficult locations and one-step mapping of planar surfaces can be carried out.
