Abstract: A distributed antenna system (DAS) includes a wideband antenna device having respective transmit and receive antennas disposed in a single package and arranged to provide mutual isolation so that in use noise from the transmit antenna is isolated from the receive antenna, whereby reception is possible at the same frequency as transmission.

Abstract: Remote monitoring of vehicle washing facilities allows a facility operator to more efficiently manage each site, particularly when combined with environmental conditions that influence the rate at which individual chemicals are used. Accurate chemical exhaustion times can therefore be predicted and communicated to the operator, and wash sequences and parameters may be altered in accordance with such environmental parameters. For example, information related to the composition of soil on a car may be monitored and used to alter the chemicals used in the wash cycle for that car. Other environmental conditions may include without limitation weather conditions, road conditions, types of vehicles, mechanical system status, vehicle temperature, etc.

Abstract: A system and method is disclosed for configuring and administering control over operations of a utility device. The utility device is described herein as being a warewash machine, but other utility devices are contemplated. A warewash controller administers control over operations of the warewash machine based on operational settings defined by the process disclosed herein. The operational settings are derived based on environmental parameters (e.g., water type, soil level, selected chemical product, etc.) specified by a field service person through a graphical user interface. If an environmental parameter is changed during the operational life cycle of the warewash machine, the operational settings are modified to accommodate for such a change. Thus, the service performed by the warewash machine is maintained at a consistent quality regardless of changes in the environment. A method for selecting the specific chemical product that will be input as an environmental parameter is also disclosed.

Abstract: A system and method is disclosed for controlling concentration of a component chemical product in a chemical solution. The chemical solution is formed in a solution tank by combining the component chemical product with water. The component chemical product is dispensed to the solution tank by a chemical dispenser that is controlled by measured conductivity readings of the chemical solution taken in the solution tank. The conductivity readings are analyzed against a conductivity setpoint to determine whether the component chemical product should be added to the chemical solution. A conductivity offset is determined and applied to the analysis thereby taking into consideration any conductivity that may be attributable to constituents of the chemical solution other than the component chemical product. Such constituents include soil washed from the articles and the water used to form the chemical solution.
