Abstract: A handheld power tool including a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, and a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory. A dust container is selectively coupled to the housing. A dust tube is coupled to the first end of the housing and in fluid communication with the dust container, wherein the dust tube is movable between an extended position and a retracted position. A fan is positioned within the housing and is operable to generate a suction air flow path through the dust tube and into the dust container, wherein the fan rotatably driven by the motor.

Abstract: A sleep monitor device for monitoring breathing and other physiological parameters is used to classify, assess, diagnose, and/or treat sleeping disorders (e.g., obstructive sleep apnea and upper airway obstruction, among others). The sleep monitor device can be a wearable device that contains one or more microphones arranged around the subject's neck when worn. Additionally, the wearable device may also include, or otherwise be in communication with, other sensors and/or measurement components, such as optical sources and electrodes. Using the sleep monitor device it is possible to identify upper airway resistances, the site of the obstruction, to monitor tissue resistance, temperature, and oxygen saturation. Early detection of the development of upper airway resistances during sleep can be used to control supportive measures for sleep apnea, such controlling continuous positive airway pressure (“CPAP”) devices or neurological or mechanical stimulators.
