The present invention is a radar platform that detects intruders and wirelessly reports to a key-fob. The entire radar platform is water-resistant and two banks of batteries are included for convenience or extended operation time. The device consists of a MicroPower Radar (MPR), a data acquisition (DAQ) element and a processor. Radar sends a short, low-amplitude signal of radio-frequency (RF) energy toward the target. This signal reflects from the target and is received as a Doppler change in signal amplitude. The radar's RF energy is in the radio frequency band and operates at much lower powers than many mobile devices such as cell phones. This Doppler System change in signal amplitude is filtered, amplified and presented to the DAQ. The DAQ converts the analog Doppler signal into a digital bit-stream and passed to the radar processor. Proprietary software analysis is performed to further filter and to make an alarm determination.

The invention relates to apparatus and a method for preparing a fine oil mist, in particular to be fed into tool lubrication ducts of a CNC machine tool.

The apparatus is turned ON/OFF solely using the standardized machine commands M08 (“Cooling lubricant ON”) and M09 (“Cooling lubricant OFF”).

At least one aerosol pump operates when regulated within a range of supply pressures. When the upper pressure value of the supply pressure range is exceeded, the pump(s) shut(s) down until the aerosol supply has been exhausted and will turn ON again when the lower pressure value of the supply pressure range is crossed downward because of aerosol consumption.
