Abstract: A device for generating microbubbles in a gas and liquid mixture and injection device, the device comprising a housing defining a mixing chamber; means for mixing solution contained in the mixing chamber to generate microbubbles in the solution; and a needle array removably attached to the housing and in fluid connection with the mixing chamber, the needle array including at least one needle.

Abstract: By employing a one or more sensors or monitors, environmental conditions and exceptions noted during the shipment of the goods and products can be monitored, stored, and eventually reported. The information about the in-transit goods and products being tracked may also be collected and transmitted by one or more wireless communication devices such as radios, transceivers, and Global Positioning System (GPS) satellites in conjunction with RF communication and/or RFID technology. Once collected, the environmental condition data may be used to assign liability for any damage that occurred to the in-transit goods and products.

Abstract: The reagent dispenser head has a piezoelectric actuator supported by a back plate, a front plate having a conical well and a fluid inlet connected by a shallow channel, and a thin, impermeable membrane disposed between the piezoelectric actuator and the well. The well has a window defined therein opening on a nozzle plate having an array of orifices which are arranged to define a predetermined image or pattern. The dispenser head is supplied with a reagent or other liquid through the fluid inlet, the fluid feeding into the well through the channel. A control system is connected to the piezoelectric actuator to provide an electrical pulse or trigger which causes the piezoelectric actuator to bend or deform, contracting the depth of the well and ejecting drops of reagent through all the orifices simultaneously, coating a substrate with reagent in the image pattern.
