A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.

Operator interface device for a plural component dispensing system

A fluid dispensing system includes a pump, a valve, and a dispenser disposed downstream of the valve and connected to the valve with a hose. To provide a steady flow rate at the dispenser, the pump charges the fluid to or above the pressure required to achieve a desired flow rate. The valve cycles between open and closed at a fixed frequency. The valve-open time is varied within that frequency to maintain the desired flow rate.

Method and apparatus for dispensing fluid

A plural component dispensing systemreceives separate fluid components, mixes the components in a predetermined ratio, and dispenses the components as mixture. Each fluid component is supplied by a separate pumpA,B to an individual variably controllable fluid regulatorA,B. Each fluid component is supplied from its individual fluid regulatorA,B through a flow meterA,B to a mixing device. The ratio of the components delivered to the mixing deviceis controlled by the individual fluid regulatorsA,B based upon the flow rates measured by the flow metersA,B.

Plural component proportioning system and method

The present invention generally relates to a device and method for stabilizing a battery pack, wherein the battery pack stabilization device has a by-pass circuit to prevent individual cell overcharge. In one embodiment, the present invention relates to an efficient balancing and monitoring system for use in an electric vehicle that utilizes nickel-zinc-based batteries. In another embodiment, the present invention relates to a device that permits over-voltage protection as well as the ability to monitor cell voltage. In still another embodiment, the present invention provides a method to coordinate multiple packs of cells within a vehicle so a driver could be aware of possible distance and time parameters, as well as a monitoring or alert system to inform the driver of reduced power, thus preventing damage to the cells.
