摘要:
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.

A pumping system (10; 100) featuring a mounting base (40; 140) having a circular portion (42) with a circumferential wall (42a', 42a") configured with at least two slots (42b) formed therein; a motor, pump and electronics assembly (50) having a housing (54, 56) with a motor (58)arranged therein, the housing (54, 56) being configured with at least two detents (54a) formed thereon; and a switching assembly (60) having a water level sensor (62a) configured to respond to a water level and turn the motor (58) on and off, the switching assembly (60) being arranged in the housing (54, 56) of the motor, pump and electronics assembly (50). The mounting base (40; 140) and the motor, pump and electronics assembly (60) are coupled together using a detent and slot arrangement so that the at least two slots (42b) receive the at least two detents (54a) for rotationally coupling together the mounting base (40; 140) and the motor, pump and electronics assembly (60) in at least two rotational orientations that differ by 180°.

摘要:
Apparatus, including a pumping system, is provided featuring a pump and a control circuit. The pump has an impeller housing configured with a slit at the top for trapped air to leave the impeller housing once the pump has been submerged. The control circuit is configured to cycle the pump on and off for a predetermined number of cycles so that the trapped air will float to the top and be expelled out the slit when the pump is cycled off. The control circuit is configured to leave the pump on after the predetermined number of cycles.
摘要:
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.
