Abstract: A device for cooling a pet includes a fan with a housing. A motor coupled with a blade positioned in the housing. The motor is electrically coupled with a power source to energize the motor to rotate the blade. At least one member is coupled with the housing. The at least one member includes a cut-out to couple the member with an animal crate to mount the fan on the crate for cooling a pet inside of the crate.

Abstract: A vent assembly has a base and a cover connected to the base. The cover moves between a closed and open position. A fan is optionally mounted for rotation in the base. A mechanism, including a strut system, raises and lowers the cover. The strut system is connected with the cover at two positions spaced from one another. When the cover is in its closed position, a retention force is provided by the strut system and is distributed about the cover.

Abstract: A vent assembly has a locking mechanism to retain its cover on its base. The locking mechanism includes a latch and linkage coupled with the latch to move the latch between a locked and an unlocked position. A post member extends from the cover to cooperate with the latch such that in a locked condition, the cover is locked with the base in a closed position. When the latch is moved to a second position, the cover is enabled to pivot away from the base to an open position.

Abstract: The present invention is directed towards an air circulation device. The air circulation device is capable of producing and directing an air current to a desired location. The air current is used to circulate stagnant air which, in turn, provides a cooling effect. Advantageously, the device is electrically powered by 12-volt direct current (DC) but is capable of producing an air current of a magnitude similar to or greater than that produced by air circulation devices which are powered by 120-volt alternating current (AC). Further, the device contains at least one retractable elongated support which allows the device to stand upright on a flat surface when the support is in an extended position. When the device is not in use, the support may be retracted so as to be protected from being damaged during transport. Still further, the device is manufactured of a polymeric material and the motor and bearings of the device are sealed.

Abstract: A method is provided for controlling a roof vent fan assembly having a fan motor operably coupled to a fan. The method comprises: monitoring an operating condition of the fan motor; detecting a jam condition of the fan based on the operating condition of the fan motor; and, upon detecting the jam condition, stopping operation of the fan motor and subsequently restarting operation of the fan motor.

Abstract: A power roof vent fan assembly having a motor and fan mounted in a body spanning an opening in the roof of an enclosure. The motor is mounted in H-shaped cross brace assembly having reinforcing ribs for vibration dampening. A shroud is secured to the body which supports a screen and includes a trim flange which forms a pocket in conjunction with the body. A bezel is telescopically received within the pocket and secured to the lower surface of the roof. A cover is provided over the top end of the assembly which is hinged on one end and adapted to be opened and closed by a cover lifting mechanism located within the pocket. The fan motor is controlled by a speed control switch also located within the pocket. The pocket in which the switch is retained includes ventilation openings for aiding heat dissipation from the switch.
