An automatic container detection and fill control device includes a number of transmitter and receiver pairs arranged generally in parallel such that a transmission from a given transmitter is directed downwardly toward an interior of a container when present in a dispensing station. At least a portion of the transmission is capable of reflection toward a given receiver. A control circuit is connected to the transmitter and receiver pairs to periodically activate a given transmitter and monitor a corresponding receiver. Preferably, the control circuit includes a microprocessor programmed and capable of determining both container presence and a product Fill level by detecting and differentiating signal strengths of reflected transmissions, and activating and deactivating a dispenser in response thereto. The control is capable of detecting the size of a container and dispensing product until the container is considered full. The control includes the ability to detect the presence of foam in a dispensed product, allow the foam to subside, and top off the product in the container. The device provides consistent container detection and fill level control regardless of ice content, prevents the waste of product due to spillage, provides truly hands free operation to allow an operator to perform other chores during the dispensing cycle, all at a very attractive cost.

Control method and apparatus to detect the presence of a first object and monitor a relative position of the first or subsequent objects such as container identification and product fill control

Control method and apparatus to detect the presence of a first object

A dispensing method and apparatus is provided to detect the presence of a container and determine the relative size of the detected container and automatically dispense a product into the detected container while monitoring the fill level of the product in the container. Dispensing is automatically discontinued when the fill level nears the top of the container. The present system also provides a timed delay to allow settling of the dispensed product and thereafter dispenses to top-off the product in the container.

A method and apparatus for controlling an ice making machine by monitoring water level in a sump used for water recirculation over an evaporator plate. Self-diagnostic means are also provided for automatic shutdown upon detection of malfunction during various cycles.
