Abstract: A damper assembly is configured for placement within a duct of a ductwork system that supplies conditioned air through a register boot to a register vent. The damper assembly includes a damper that is configured to articulate from a deployment configuration, which facilitates advancement of the damper through the register boot and into the duct, to an operational configuration, in which the damper is positioned within the duct and able to selectively control how much conditioned air being supplied through the duct is permitted to pass by the damper and exit the register vent. The damper assembly includes an elongated deployment member that extends from the damper and is configured to facilitate advancement of the damper through the register boot and into the duct.

Abstract: A modular damper system is configured for installation in a ductwork of a building that supplies conditioned air through a register vent of the building and includes a damper unit, a control module and a power module. The damper unit is mountable upstream of the register vent and includes a damper that is movable between a closed position and an open position. The control module includes a controller that provides control commands to the damper unit and includes a housing that is configured to be secured to the ductwork at a position between the register vent and the damper unit. A power module is electrically coupled to the control module to provide power to the control module and includes a housing that is configured to be secured to the ductwork at a position between the register vent and the damper unit.

Abstract: A damper assembly for use in a round forced air duct feeding a register vent through a register boot includes a damper frame having a frame periphery with a first side and a second side that is at least substantially parallel with the first side, the first side and the second side each having a length that is greater than a distance between the first side and the second side. A damper blade is pivotable relative to the damper frame about an axis of rotation, at least substantially parallel with the first side and the second side, between an open position and a closed position. A flexible outer seal extends outwardly from the frame periphery of the damper frame and is at least substantially circular in order to seal against an inner surface of the round forced air duct.

Abstract: A damper assembly is configured for deployment in a forced air duct that supplies conditioned air through a register boot to a register vent secured relative to the register boot. The damper assembly includes a damper unit and a deployment strap. The deployment strap includes a first end secured relative to the damper unit and an opposing second end and has a length that is sufficient to position the damper unit in the forced air duct when the second end of the deployment strap is secured relative to the register boot. When in a deployment configuration, the damper unit has a reduced profile to facilitate deliver of the damper unit through the register boot and into the forced air duct. When in an operational configuration, the damper unit is configured to operate a damper blade between a closed position and an open position.

Abstract: An electrode humidifier device having a cartridge and a reconfigurable steam nozzle, connected to the cartridge that may be changeable between a direct and a remote mounting. Fill and drain valves on a manifold may be operated to add or drain water, respectively, in the cartridge. A sensor may indicate a water level in the cartridge. A controller may be connected to the sensor, and the fill and drain valves. A steam output capacity of the cartridge may be maintained at a predetermined magnitude by controlling the level of water with a controller. The cartridge may have one or more handles for easily inserting or removing the cartridge in a housing. The manifold may be installed in the drain pan for easier cartridge replacement. The humidifier device may be directly mounted on an air duct of a heating system or can be installed remotely.

Abstract: A damper assembly is configured for deployment in an existing forced air duct that supplies conditioned air through a register boot to a vent cover secured relative to the register boot. The damper assembly includes a damper frame having an at least substantially obround shaped frame periphery and a damper blade having an at least substantially obround shaped blade periphery. A damper insert arm is biased into a deployment configuration in which the damper insert arm is at least substantially perpendicular to the damper frame and is movable into an operational configuration in which the damper insert arm is at least substantially parallel with the damper frame. A latch is configured to releasably engage the damper insert arm in order to hold the damper insert arm in the deployment configuration.

Abstract: A damper assembly is configured for placement within a duct of an existing ductwork system, the duct supplies conditioned air through a register boot to a register vent within a room. The damper assembly includes a damper blade that is movable between a closed position and an open position. A damper motor is operably coupled to the damper blade and is configured to move the damper blade between the closed end position and the open end position. A microphone provides an output signal that is representative of sounds sensed by the microphone. A control module is operably coupled to the damper motor and the microphone and is configured to control operation of the damper motor based at least in part on the output signal provided by the microphone.

Abstract: A damper assembly for use in a forced air duct feeding one or more air register vents includes a damper frame having an outer frame periphery and an inner frame periphery, the inner frame periphery defining an air flow aperture, and a damper blade that is pivotally secured relative to the damper frame and is pivotable between an open position and a closed position. An outer seal extends radially outwardly from the outer frame periphery of the damper frame and is configured to make a seal against an inner surface of the forced air duct when the damper assembly is deployed within the forced air duct.

Abstract: A damper is configured for placement within a ductwork system that includes a duct supplying conditioned air through a register boot to a register vent within a room of a building. The damper includes a damper body and a damper blade pivotally secured relative to the damper body and a resilient seal extending radially outwardly from the damper blade, the damper blade being pivotally movable between a first position in which air flow is restricted and a second position in which air flow is less restricted. A drive motor is secured relative to the damper body and is configured to move the damper blade between the first position and the second position. A deployment strap extends downstream from the damper body and facilitates placement of the damper body in a duct from an installation location within or downstream of the register boot.

Abstract: A system for automatically identifying a needle insertion location from a medical diagnostic image, such as an MRI image, and providing a visual indication of the needle insertion location is disclosed. A grid plate is located proximate to an anatomical region and is preferably incorporated in an MRI support structure utilized to immobilize the anatomical region. An MRI scanner obtains an MRI image of the anatomical region, and an MRI technician places a marker on the MRI image, identifying the needle insertion location. The MRI image and the marker are transferred from the MRI scanner to another device, such as a tablet computer, which is configured to convert the MRI image and the marker to coordinates and an insertion depth. A visual indicator is located proximate to or integrated with the grid plate that provides the needle insertion coordinates and insertion depth to the MRI technician.

Abstract: A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter's processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.
