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 signal processor that receives signaling containing information about a low level of a liquid sensed in an appliance reservoir to be supplied to an appliance that uses the liquid to dispense a flavored beverage, and also about when the appliance reservoir is refilled based upon an indication that forms part of an appliance reservoir refill level calibration procedure programmed by an appliance user; and determines corresponding signaling containing information about automatically refilling the liquid in the appliance reservoir, based upon the signaling received.
Abstract:
Apparatus for providing liquid from a reservoir of liquid contained in a vehicle/vessel or other equipment, featuring a pump for pumping liquid having a pump housing outlet nozzle; and a back flow preventer assembly having an inlet end to couple to the outlet nozzle, having an outlet end to couple to an outlet hose for connecting to an outlet exiting a wall of a vehicle, vessel or other equipment, and having a duckbill-type check valve to provide liquid being pumped in one direction from the reservoir of the vehicle, vessel or other equipment to the outlet exiting the wall of the vehicle, vessel or other equipment via the outlet hose, and also configured 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, vessel or other equipment is above the outlet nozzle, so as to prevent on an on/off oscillation of the pump depending on the volume of residue liquid left in the outlet hose.
Abstract:
A pumping system featuring a pump chamber configured with a central portion having a tangential outlet, and configured with a tubular coupling end portion having inwardly flexible rim portions on one side; and a mounting base, having a circular portion with an inner circumferential rim configured to receive and engage the inwardly flexible rim portions of the tubular coupling portion of the pump chamber so as to be rotationally coupled to the pumping chamber so that the pumping chamber may be rotated 360° in relation to the mounting base.
Abstract:
An inline gas/liquid infusion system featuring an electronic control logic and subsystem having a signal processor configured to: receive signaling containing information about a liquid pressure of an incoming liquid provided from a pump to an inline gas liquid absorption device and about a gas pressure of an incoming gas provided to the inline gas liquid absorption device; and determine corresponding signaling containing information to control the liquid pressure of the incoming liquid provided from the pump to the inline gas liquid absorption device in order to provide real time adjustable set point output levels of gas absorption in the inline gas liquid absorption device, based upon the signaling received.
Abstract:
A rocker switch assembly features a rocker switching mechanism and a rocker base housing. The rocker switching mechanism has a switch cover and rocker configured to rock between rocking positions in response to rocking switch forces applied thereon, and provide a rocking switch actuator force. The rocker base housing has a piezo buzzer and rocker switch circuitry, e.g., including contacts/terminals. The piezo buzzer is configured to respond to the rocking switch actuator force, and provide signaling from the piezo buzzer to rocker switch circuitry, based upon the rocking switch actuator force applied.
Abstract:
A control valve features a first housing and a second housing. The first housing includes a first inlet port having a first inlet port orifice member with a first inlet port orifice size configured to provide a first inlet fluid with a first inlet volumetric flow rate, the first inlet port orifice member being detachably coupled inside the first inlet port; includes a second inlet port having a second inlet port orifice member with a second inlet port orifice size configured to provide a second inlet fluid with a second inlet volumetric flow rate, the second inlet port orifice member being detachably coupled inside the second inlet port; and includes a first housing rim configured to extend from the first fixed inlet and the second fixed inlet. The second housing includes a second housing rim coupled to the first housing rim and configured to form a mixture chamber to mix the first inlet fluid received from the first fixed inlet orifice and the second inlet fluid received from the second fixed inlet orifice and provide a mixture chamber fluid; and an outlet port having an outlet port orifice with an outlet port orifice size configured to provide the mixture chamber fluid as an outlet port fluid having an outlet volumetric flow rate. The outlet port fluid has a mixture ratio of the first inlet fluid and the second inlet fluid for a particular application that depends on dimensions of the first inlet port orifice size, the second inlet port orifice size and the outlet port orifice size.
