Abstract: An apparatus includes a reservoir to hold a volume of liquid, a port to inject a flow of gas into a lower portion of the reservoir, and a structure to transform the flow of gas into one or more streams of bubbles in said liquid. The reservoir has a port for injecting the gas into a lower region of the volume of liquid and has a top opening to release the injected gas therefrom. The apparatus includes one or more active electronic or optical devices located in the reservoir or located physically adjacent and in thermal contact with the reservoir such that the volume of the liquid is able to absorb part of heat produced by the one of more electronic or optical devices.

Abstract: A device for moving air comprising a piezoelectric element attached to a planar body. The planar body is configured to oscillate at a movable end generating an airflow in response to applying alternating electric current to said piezoelectric element. The device further comprises a partial cavity defined by a base plate, a first wall and a second wall which surrounds the movable end of the planar body. The base plate further comprises an opening located proximate to said movable end of the planar body. In operation the air flow generated by the planar body is forced out of the device through the opening.

Abstract: A garden watering device is configured for use in handheld and ground-based operation. The garden watering device includes a device body having a water inlet and a handle. The garden watering device also includes at least one water distribution member adapted to spray in multiple patterns. In one example, the at least one water distribution member includes an elongate tube with a series of discharge outlets and a multi-pattern head with at least one flow outlet. The garden watering device also includes a flow route selector that routes water to either the elongate tube or the multi-pattern head.

Abstract: A vacuum apparatus for sealing an airtight bag includes a tongue in fluid communication with a vacuum chamber and base members that close around and seal a section of the bag. The once closed, the apparatus facilitates fluid communication between the interior of the airtight bag and the vacuum chamber, allowing actuation of the vacuum chamber to result in evacuation of air from the bag. The tongue may take the form of a removable tube device or may be designed to puncture the bag. The apparatus may be wholly removable after evacuation of the bag, or some part of the apparatus may remain on the bag in order to maintain the airtight seal.

Abstract: A multi-purpose watering device that operates as a handheld device and ground based watering device. The device consists of a long handle leading to a turret sprinkler with water distribution on at least two sides. One side is used in a ground based position to water small to medium area lawns and the other is used for watering when the device is used in a held position. A valve on the turret face allows the operator to switch select which will distribute water. The device also contains a rotating sprinkler head suited for watering of large areas. When the rotating head is actuated, water is redirected from the turret head to the rotating head.
