Title: Innovations by Inventor Ming Zhang
Introduction
Ming Zhang is an accomplished inventor based in Akron, OH (US). He holds a total of 4 patents that showcase his innovative contributions to technology, particularly in the field of beverage dispensing and refrigeration systems.
Latest Patents
One of his notable inventions is the "Sold Out Sensing Device and Method." This control for a beverage dispenser monitors its operation to detect a beverage sold-out condition. The control senses the voltage demand of a pump motor as it pumps the beverage from a source to a dispensing valve. If the sensed voltage is high, it indicates that the pump is encountering resistance and fluid is present. Conversely, a low sensed voltage indicates that the pump is not pumping any liquid, signaling that the container is empty. The control utilizes a software routine to sense average current requirements during dispensing and adjusts the reference voltage based on historical averages from prior dispense cycles. This innovative control can learn over time and compensate for physical changes in hardware and the environment, ensuring accurate sold-out determinations.
Another significant patent is the "Ice Bank Control with Voltage Protection Sensing." This invention regulates the size of an ice bank and prevents short cycling of the compressor while ensuring operation at desired voltages. A microprocessor-based control circuit includes a line voltage sensing circuit combined with an ice bank sensing circuit. The ice bank sensing circuit uses conductivity sensing between two probes to determine refrigeration needs. The microprocessor continually monitors these probes and the line voltage to ensure it remains within design limits for the refrigeration compressor.
