  • Patent number: 6981914
    Abstract: A removably insertable rear cabin air vent for installation between the rear side flap and the rear wall of the soft top of an off road or utility vehicle. The vent is inserted and held in place between the rear sidewall flap and the rear of the soft top by any known means such as by sewing and adhesives. Certain soft have a zipper attaching the sidewall flap to the soft top and, have an overlapping flap outside the zipper which is held in place by mutually engaging strips of hook and loop material. The preferred means of attaching the vent is by placing hook and loop material along the outer surfaces of the vent which match with the existing strips in the sidewall flap and soft top, allowing for the removable insertion of the vent between the existing strips of hook and loop material in a desired location.

  • Patent number: 6981916
    Abstract: A ridge vent, roof ridge vent installation, and method of installing a ridge vent is provided. Preferably, the ridge vent includes a ventilation material that has opposite longitudinally-extending side edges that are covered with an air permeable filter material. A longitudinally-extending central section of the vent is not covered by the air permeable filter material, is transparent, and enables a ventilating air flow to pass through the vent in a manner requiring only a single pass through the air permeable material. This permits greater air flow through the vent, and the transparent central section simplifies and enables accurate placement of the vent on the roof ridge.

  • Patent number: 6981915
    Abstract: A control system for controlling airflow through a vent. The system includes a vent assembly having a frame. The frame includes an opening to allow air to flow through the frame. The vent assembly also includes a movable damper for variably restricting the fluid flow through the opening in the vent assembly, a motor for controlling movement of the damper, and a sensor for determining the position of the damper. In addition, a controller is provided to control the motor to vary the position of the damper to thereby vary the airflow through the opening in the vent assembly.

  • Patent number: 6979260
    Abstract: A device to prevent indoor release of carbon monoxide and smoke from indoor combustors (stoves, furnaces, fireplaces, etc.). The device is based on a discovery that safe operation of indoor burners requires the air pressure in the room housing the burner to be relatively high in order to prevent generation of reverse chimney flow and indoor release of exhaust gas (smoke and carbon monoxide), which are dangerous to building occupants. This device solves the problem by increasing the building internal pressure.

  • Patent number: 6979257
    Abstract: A pressure control system including an inflow unit for admitting pressurized air into a cabin, an outflow unit including a motor for operating a valve to discharge air from the cabin at a predetermined rate based on an motor control signal that sets the motor speed, a control unit, and an air pressure sensor within the cabin for determining a pressure signal. The control unit receives the pressure signal and computes a pressure rate of change error signal to set the motor control signal. The outflow unit, control unit, and air pressure sensor form a feedback control loop independent of motor speed, valve speed, or valve position feedback.

  • Patent number: 6974376
    Abstract: A flow straightening grid 30 is provided at an area where the air flow turns about 180 degrees in an air path 23, or in the vicinity thereof. Because of this, the air flow can be prevented from being disturbed in the air path 23 and, therefore, noise caused by the disturbance of the air flow can be reduced effectively.

  • Patent number: 6974381
    Abstract: An air flow producer of non-rectangular shape is adapted for installation in a rectangular opening of a drop ceiling. In preferred form, the producer has a circular housing with an open bottom covered with a grill. A fan with a rotary blade assembly is mounted in the housing to produce a downward air flow, and a circular metal band surrounding the rotary blade assembly defines an air discharge zone centered in the grill and an annular air intake zone surrounding the discharge zone. Flow rates are optimized by positioning the band close to the grill. The grill is preferably integrally molded with a rectangular flange that seats in the drop ceiling opening. The flange supports the housing from the framework and closes the opening to prevent the producer from drawing air from the plenum above the drop ceiling.

  • Patent number: 6974442
    Abstract: Methods and devices for extracting thermal energy from the core body of a mammal are provided. In practicing the subject methods, a portion of the mammal, e.g. a limb or portion thereof, is placed in a sealed enclosure to produce an enclosed portion of the mammal. A surface of the enclosed portion of the mammal is then contacted with a low temperature medium under negative pressure conditions for a period of time sufficient to provide for the desired core body thermal energy extraction. The subject methods and devices find use in a variety of applications, e.g. providing relief from temperature sensitive disorders, such as multiple sclerosis, and the treatment of hyperthermia, among other treatments. The subject methods and devices are particularly suited for use in enhancing the physical ability of a mammal.

  • Patent number: 6974383
    Abstract: A cabinet for air handling equipment includes a door assembly having features such as inner and outer door panels being held together and sealed by double-sided tape, which acts as a thermal break, a latch that prevents a door gasket from being crushed due to positive or negative air pressure within the cabinet, and a doorframe that is easy to assemble and install for either right-hand or left-hand swinging doors. To assemble adjacent pieces of the doorframe, sheet metal tabs of one piece are inserted into slits of the other piece. The tabs are then twisted to hold the adjacent pieces of the doorframe together.

  • Patent number: 6960128
    Abstract: In an air shower apparatus, an inlet duct guides the air so that the air is directed along a first flow axis of the air, and a variable condition area communicates fluidly with the air flowing out from the inlet duct at at least one side in a direction perpendicular to the first flow axis, to generate a fluctuation at the variable condition area in at least one of a pressure to be applied to the air flowing out from the inlet duct at the variable condition area and a mass flow rate of a supplemental air to be applied from the variable condition area onto the air flowing out of the inlet duct in a fluctuating direction oblique to the first flow axis so that a second flow axis of the air passing the variable condition area is frequently deflected from the first flow axis by the fluctuation.

  • Patent number: 6958010
    Abstract: A fan unit centrally located within a crawl space includes a fan, a fan motor, an inlet grill, and an outlet grill. A timer connected in the power supply activates the fan motor at periodic predetermined time intervals to move the crawl space air through the fan unit. The fan unit is located and orientated to create a negative pressure to pull air into the crawl space through wall inlet vents and to also create a positive pressure to force air out of the crawl space through wall outlet vents. An outside humidity sensor can be used to insure the outside air has a lower percent humidity than that desired in the crawl space and an inside humidity sensor is used to turn the fan unit off if the crawl space humidity is below an acceptable limit. A temperature sensor is used to turn the fan unit off when the crawl space air temperature gets too low.
