Abstract: A radio frequency extender device has a radio frequency transmitter, a receiver positioned at a location remote from said radio frequency transmitter, and a cable conductor extending between said radio frequency transmitter and said receiver. The cable conductor has one end spaced away from said radio frequency transmitter and an opposite end spaced away from the receiver. The cable conductor adapted to transmit the transmission from the radio frequency transmitter to the receiver. The receiver produces a humanly perceivable signal from the transmission from the radio frequency transmitter. The radio frequency transmitter can be an instrument or a vibration sensor with a Bluetooth™ device connected thereto.

Abstract: A system for forming mini microbubbles has a housing with an upper end and a lower end, a motor positioned in the housing, a shaft connected to the motor, a plate affixed to the shaft and extending radially outwardly therefrom, and an air line connected to the housing so as to open in a space within the housing adjacent the lower end thereof between the plate and the motor. The plate is positioned inwardly of the lower end of the housing. The plate has a smooth lower surface. The motor is a submersible motor.

Abstract: A system for forming mini microbubbles has a motor, a shaft attached to the motor, a displacer attached to the shaft for mixing a media with a liquid, a discharge plate positioned adjacent the displacer, a housing adjustably attached to the discharge plate, and a media chamber fluidly connected with the discharge plate. The motor rotates the shaft. The discharge plate has a discharge hole formed therein. The media chamber is fluidly connected to the discharge hole of the discharge plate. The discharge plate is positioned between the motor and the displacer. The displacer is positioned within the housing. The media chamber can be positioned between the motor and the discharge plate.

Abstract: A system for algae production has a first tank with an interior containing aerobic bacteria and waste water therein, a first aerator cooperative with the interior of the first tank for passing bubbles into the waste water and the aerobic bacteria in the interior of the first tank, a first collection chamber positioned above the first tank so as to collect carbon dioxide from a reaction of the aerobic bacteria with the waste water, a second tank having an interior containing algae and water therein, and a second aerator in fluid communication with the first collection chamber. A second aerator serves to pass carbon dioxide from the first collection chamber as mini microbubbles into the algae and water of the second tank. A second collection chamber is positioned above the second tank so as to collect oxygen produced from the algae. The second collection chamber is in fluid communication with the first aerator.
