Abstract: A portable device for treatment of migraine having a desktop unit defining an airpath through a desiccant, a heat sink, an air mover and an air outlet, and a tubeset including a tube having one end for connecting to the desktop air outlet and a second end connected to a handheld unit, the handheld unit including a water compartment, and a nebulizer/transducer for introducing water droplets into the air stream. A nasal pillow is provided at the end of the handheld unit for placing against a user's nose.

Abstract: The present invention monitors the RF drive circuitry of a linear laser transmitter. In one preferred embodiment of the present invention, a filtered RF signal from the monitor diode is amplified and then input to a peak detector. The output of the peak detector is then fed to the input of a threshold detector, wherein the threshold detector determines whether the output of the peak detector is above a predetermined threshold. If the output of the peak detector falls below the predetermined threshold an alarm is generated at the status monitoring ports of the laser transmitter.
