An airway obstruction correction apparatus including an expandable bladder configured to fit within a user's external auditory canal, a pump configured to expand the bladder with a pumped fluid, a passage coupled with the pump and with the bladder and configured to convey a fluid between the pump and the bladder, a microcontroller coupled with the pump and configured to affect an activation condition of the pump, and a reservoir coupled with the pump and configured to retain sufficient fluid to expand the bladder into contact with a surface of the auditory canal when transferred to the bladder by the pump. At least one of a local data processing means and/or a remotely located data processing means can be configured to receive data from the apparatus and transmit data to the apparatus via a data networking means and/or at least one of a wired or wireless signal. According to a method using an apparatus configured as described, a detected indication of an obstructed airway causes the apparatus to stimulate a user and induces an involuntary airway clearing response.

Apparatus, system and method for detecting and treating airway obstructive conditions during sleep

A lifter including tongs; an electric motor having a stator, a rotor, and one or more windings and a shaft operatively coupled with the first tongs for actuating the first tongs to an open position for receiving a load and actuating the first tongs to a closed position for engaging the load; and a vector drive controller electrically coupled to the electric motor for controlling the operation of the electric motor. A method of handling a load with a motorized lifter including at least one set of tongs and an electric motor coupled to the tongs, the method including moving the tongs of the motorized lifter to a home position by operation of the electric motor, wherein the electric motor is controlled by a vector drive controller; moving the tongs out of the home position; placing the tongs over the load; and positioning the tongs against the load by operation of the vector drive controlled electric motor so as to frictionally engage the load with the tongs.

Motorized lifter

The present invention provides systems and methods of dispensing liquids. In one embodiment, the system includes a pump with a removable pump module with at least one displacement piston and at least one piston valve. A motor and base assembly provide the supporting components of the pump which can be used in environments where precise small volumes of ultra-pure liquids must be transferred from a reservoir to a point of use. The preferred embodiment of the system prevents contaminants and air bubbles from being introduced into the liquid to be dispensed by placing a filter across the discharge line downstream from the pump, and providing a separate drawback line for performing the drawback of the liquid in the dispensing nozzle.

A rotary/reciprocating liquid dispensing pump for dispensing liquids in the nanoliter range has a narrow radial slot extending longitudinally from an end of a reciprocating, rotating cylindrical piston sliding in a smooth cylindrical bore of a pump housing at a closed end thereof, which slot extends outwardly to the periphery of the piston. The piston is selectively positioned in alignment with one of a plurality of circumferentially spaced small diameter radial passages within the housing opening directly to the cylindrical bore in the path of rotation of said slot. The ports thereof opening to the cylindrical bore are spaced circumferentially a distance in excess of the width of the slot. A linear liquid dispensing pump apparatus including such pump includes a stepping motor and an electromagnetic clutch/braking mechanism concentrically surrounding a lead screw, and the lead screw is threadably engaged with a stepping motor tubular rotor shaft. An anti-backlash assembly operatively couples the stepping motor tubular rotor shaft to the lead screw. The stepping motor is incrementally pulsed and the electromagnetic clutch braking mechanism energized for selective incremental rotation of the lead screw.
