Abstract:
Apparatus features a microcontroller configured to: receive signaling containing information about a measured change of a magnetic field created by a magnetic circuit driving a motor; and determine corresponding signaling containing information about the speed of rotation of the motor, based upon the signaling received. The microcontroller provides control signaling containing information to control the operation of the motor, including where the motor control is used to control the flow of fluids from a pump. A Hall Effect Sensor is used to sense the magnetic flux and provide the signaling in the form of a feedback signal for implementing motor control. The motor housing has a slot, the Hall Effect sensor is mounted external the motor housing over the slot, and a ferromagnetic bridge is arranged over the Hall Effect sensor to close the magnetic circuit and cause more flux to go through the Hall Effect sensor.
Abstract:
A pump includes a liquid housing having a liquid chamber with a piston/diaphragm assembly arranged therein that responds to a suction stroke and draws liquid into the liquid chamber, and responds to a pressure stroke and provides liquid from the liquid chamber; and a gas housing having a slide valve assembly separating first and second gas chambers. The slide valve assembly responds to a suction-to-pressure-force at the suction stroke conclusion, changes from a suction-to-pressure stroke state, provides gas from the first to second gas chamber through the slide valve assembly, and provides the pressure stroke so liquid passes from the liquid chamber; and responds to a pressure-to-suction-force at the pressure stroke conclusion, changes from the pressure-to-suction stroke state, provides gas from the second chamber through the slide valve assembly, and provides the suction stroke so the liquid is drawn into the liquid chamber.
Abstract:
Apparatus includes a pump for pumping liquid having a pump housing outlet nozzle; and a back flow preventer assembly having an inlet end coupled to the outlet nozzle, having an outlet end coupled to an outlet hose for connecting to an outlet exiting a wall of a vehicle, and having a duckbill-type check valve to provide liquid being pumped in one direction from the reservoir of the vehicle to the outlet exiting the wall of the vehicle via the outlet hose, and to prevent residue liquid left in the outlet hose from flowing back into the pump and returning to the reservoir once the pump has completed pumping if the outlet exiting the wall of the vehicle is above the outlet nozzle, and to prevent an on/off oscillation of the pump depending on the volume of residue liquid left in the outlet hose.
Abstract:
A pump, having a pump housing with an impeller arranged therein, features an anti-airlock valve assembly configured with a valve housing having a passageway configured with a vent hole to allow air to bleed out of the pump housing into the atmosphere so liquid can fill the pump housing, rise and engage the impeller in order to get the pump running; and a valve ball arranged in the passageway, the valve ball configured to rest against one part of the passageway so air can pass out of the vent hole, and also configured to be light or buoyant enough to respond to the liquid filling the pump housing, float upwardly and rest against another part of the passageway so as not to allow water to escape readily from the vent hole after the liquid rises to a sufficient level and substantially engages the impeller.
Abstract:
A high viscosity portion pump system has a single piston portion pump having a piston/diaphragm assembly arranged on a piston shaft forming liquid and gas chambers, which moves from a starting-position and provides high viscosity fluid from the liquid chamber when gas is received by the gas chamber; has an elastic member arranged on a retainer coupled to the shaft in a compartment in a pump housing, which moves the assembly back to the position and draws further fluid into the liquid chamber when the gas is released; and has a piston position sensor that responds to the position of the shaft and provides signaling containing information about when the assembly is in the position or completed a stroke from the position. A gas control system includes a signal processor that receives the signaling, and provides corresponding signaling containing information about when to provide or release the gas.
Abstract:
A pump system features a power adapter and a pump having a signal processor. The power adapter includes voltage settings that respond to a voltage setting by a user and provide a selected voltage. The signal processor receives signaling containing information about the selected voltage supplied to a motor to run the pump, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received.
Abstract:
A smart phone for using to optimize the energy production of a solar panel in real time by a user features a signal processor to receive GPS signaling containing information about the global position of the smart phone, and input signaling containing control information to initiate a GUI algorithm in the signal processor to determine visual and/or audio cues for a user on a proper alignment of a solar panel for optimal solar energy collection efficiency; and provide display imaging signaling from a screen of the smart phone, or audio signaling from a speaker in the smart phone containing information about the visual and/or audio cues for the user on the proper alignment of the solar panel for optimal solar efficiency, so as to enable the user to simultaneously adjust the planar orientation of the solar panel having the smart phone placed thereon, based on the visual and audio cues.
Abstract:
A small lightweight battery operated remote switched bilge pump is provided weighing less than one pound for installing in a small watercraft, including a kayak, canoe, sailboat, row boat, dingy, featuring a bilge pump comprising a low voltage inline pump, a housing having a compartment with an integrated strainer base and configured to receive the low voltage inline pump, and having a watertight compartment to receive lightweight batteries to power the bilge pump for about 1.5 hours, and a switch assembly to selectively operate on/off functionality of the bilge pump remotely; and a Velcro® arrangement to couple the bilge pump to a surface of the small watercraft to allow easy installation of the bilge pump in about 15 seconds to perform bilge pump functionality without drilling or making holes in the small watercraft, and to allow easy removal of the bilge pump for cleaning and battery replacement.
Abstract:
Apparatus, including a carbonation chamber, is provided that includes a mixing and metering member and a gas adjustment member. The mixing and metering member is configured to respond to a fluid, including water, and an adjustable amount of gas, including CO 2 , and may be configured to provide a mixture of the fluid and the gas. The gas adjustment member is configured to receive the gas, including from a gas inlet, and to provide the adjustable amount of gas to the mixing and metering member, based at least partly on an adjustable axial relationship between the mixing and metering member and the gas adjustment member in order to control a desired carbonation level of the mixture.
