A geographic database of the subject invention interfaces with the Point-of-Sale system in a Quick Service Restaurant to optimize the sequence and pairing of delivery orders based on customer location, driver availability and prioritized real-time information.

The system optionally communicates with GPS-enabled cellular or Wi-Fi communication devices to provide turn-by-turn navigation information to the driver and enable supplementary location information and other communication exchanges between the driver and the dispatch location during the delivery process.

The system may be configured to aggregate a number of local delivery areas into a virtualized delivery system allowing further optimization of driver resources and to enhance capacity utilization across participating order-dispatch locations.

A light fixture assembly including an illumination assembly in the form of one or more light emitting diodes is interconnected to an electrical energy source by a conductor assembly and control circuitry.

The present invention is a geothermal exchange process to deliver water, in a closed loop ground to water system, at temperatures approaching that of ground water. Such water temperatures were heretofore only achievable with ground water systems. Optimum energy saving and performance of ground coupled heat pumps are directly linked to heat exchange between a circulating water loop and ground temperature. This invention allows for the optimization of energy and performance. The efficiency of heat pumps diminishes with descending outside air temperatures. This invention allows for the manipulation of entry water temperatures to stem the problem of diminishing efficiencies. The water system makes use of a uniquely designed geothermal exchange module with increased conductivity to maximize heat transfer into the water.

A vacuum processing apparatus is constituted of the following portions: a processing container with the bottom, capable of drawing vacuum; a placement platform installed in the container; a heating portion for heating a substrate on the platform; a processing gas-feeding portion for feeding a processing gas into the container; a partitioning portion surrounding a space between the platform and the bottom of the container and partitioning off the space from a processing space in the container; a purge gas-feeding portion for feeding a purge gas into the space surrounded by the partitioning portion; a purge gas-discharging portion for discharging the purge gas from the space surrounded by the partitioning portion; a control portion for controlling the purge gas-feeding portion and/or the purge gas-discharging portion so as to regulate the pressure in the space surrounded by the partitioning portion; and a temperature-detecting portion penetrating the bottom of the container, inserted in the space surrounded by the partitioning portion, and having the top end in contact with the platform. The partitioning portion has the lower end in surface-contact with the bottom of the container. The control portion regulates the pressure in the space surrounded by the partitioning portion to a pressure higher than that in the processing space in the container.

A vacuum collector assembly comprises a mountable hitch having support posts connected to one another by horizontal supports and a hinge mechanism for connecting to a trailing carriage. The trailing carriage includes a lift assembly and an engine support frame for mounting thereon an engine operating conjunctively with an impeller assembly for developing negative pressure within a blower housing that is connected in between a receptacle hood and a lawn cutting deck.
