Multiple RF read zone system

A multizone RF read / write system for conducting transactions with vehicles traveling at high speeds. A first RF read zone is created, preferably by use of a first gantry that extends over at least one lane and contains at least one RF source that creates a large powerful RF read zone for reading or reading and writing to a transponder on a passing vehicle. Additional RF read zones arranged in tandem with the first RF read zone are created by at least one additional RF source that is located on an additional gantry extending over at least one lane, or located on the first gantry. Accordingly, multiple RF read zones are created to conduct transactions with passing vehicles. In one aspect, the multiple RF read zones can be used to ensure that tolling transactions with a single vehicle are more likely to be completed and have a higher degree of accuracy. In another aspect, the multiple RF read zones each employ a different RF technology so that multiple types of RF toll tags can be read and written.

Direct current electrical controls for heating systems

A method and apparatus for controlling the normal operation of a hydronic heating system, (including AC powered, gas-burning hot water boiler, multi-zone systems) using a DC power source, such as battery power, as the primary continuous source of electricity. Control functions minimize the consumption of electric power during normal operation, and eliminate standby electric consumption in order to extend the life of the batteries and maximize the run-time of the heating system. A DC to DC converter supplies low voltage DC power to the zone thermostats, and also supplies the proper voltage through zone relays to operate DC zone pumps. By allowing the use of DC power for the thermostats and zone pumps, the system eliminates the need for transformers, zone valves, and AC circulators, resulting in a large savings in electrical consumption and the elimination of the standby electric demand ("phantom load") common in conventional hydronic heating systems. A DC to AC inverter is dedicated to supply AC power for a hydronic (hot water) boiler. The inverter is switched on by relays only when needed, thereby eliminating the "phantom electric load" consumed by most boilers when standing by. A time delay relay circuit allows the boiler to go through its proper shutdown sequence before power is removed. This control system does not require any internal modification to the other heating system components.

Continuous fan control in a multi-zone HVAC system

A multi-zoned HVAC system includes a control for independently determining the amount of airflow delivered to each zone within the HVAC system. The control determines nominal zone airflow and continuous fan airflow levels for each zone based upon a user selected fan airflow level and the relative size of each zone in the HVAC system. The control determines the desired system airflow for the entire system once the continuous fan airflow levels for each zone are determined. The HVAC system provides a continuous fan airflow to each zone independently of the continuous fan airflow delivered to any other zone and irrespective of the relative size difference of the zones.

Modular heat distribution unit for hydronic heating systems

A compact modular heat distribution unit for a hydronic heating system connects to a hot water source, to supply and return pipes that lead to heating zones of the building, and, optionally, to an indirect water heater. The module is preferably assembled off-site in a factory setting to contain all components of a typical hydronic heating system except for a hot water source and the building heating pipes. The module includes heating zone distribution sub-modules for the different heating zones of the building. A three-dimensional frame supports the heating zone distribution sub-modules. The module may be used in any multi-zone system including hot water baseboards, hydronic radiant heat floor pipes, swimming pool heaters, ice melt systems or in any combination of these zones.
