A computer system, configured for bandwidth-efficient use of internet resource has a storage system, in which are stored: (i) web data selected for storage based on (a) frequency of occurrence in downloads from the World Wide Web as determined with reference to a relevant population of users over a relevant period of time or (b) relative importance to the relevant population of users over the relevant period of time; and (ii) instructions that establish a local-reference computer process, running within a web browser computer process, which, responsive to a URL entered into a browser established by the web browser computer process, first accesses the storage system to determine whether web data corresponding to the entered URL is stored in the storage system, and, if so, causes the corresponding web data to be retrieved locally from the storage system and displayed in the browser.

An automatic refueling station and method detects the arrival of a vehicle to be refueled at the refueling station. Upon detection of the vehicle, the vehicle is polled by the station to obtain information from the vehicle which identifies the vehicle and the customer associated with the vehicle. The information is stored on an identification transponder or tag affixed to the vehicle windshield. The system uses the identifying information to access a vehicle database and a customer database. The vehicle database can provide information about the vehicle such as the location of the vehicle's fuel filler opening, the size of the vehicle and other information related to a recommended fuel filling rate for the vehicle. The customer identifying information is used to access the customer database to obtain information such as customer billing information and the amount of fuel being purchased. Using the data retrieved from the databases, a refueling module can locate the fuel filler opening and refuel the vehicle at a optimum fuel rate. A network of sensors deployed in the refueling area facilitate the refueling procedure. A vision system aides in locating the fuel filler opening and guiding the fuel filler nozzle to the opening. Other sensors such as force, torque, infrared, sonar, magnetic and hall effect sensors aide in guiding the nozzle into a docking position with the vehicle. Other sensors in the area provide monitoring of the area to prevent hazards such as collisions between vehicles and persons and criminal activity in the area.

An apparatus for determining the position and/or orientation of a transducing head positioned on one side of and close to a rotating transparent-core magnetic storage disk. Light is introduced into the disk to establish total internal reflection therein. A detector disposed on the other side of the disk opposite the head detects the intensity of light on the interior region of the disk. The detected intensity is representative of the separation of the head from the disk.

The pumping apparatus disclosed herein recovers pumping energy required in feeding solution to a reverse osmosis unit. The reverse osmosis unit generates a purified product but also a concentrate stream which is discharged at a pressure only slightly lower than the feed pressure. The discharge flow is utilized to displace hydraulic fluid in a work exchange vessel and this displaced fluid is then boosted in pressure and supplemented by an additional flow of hydraulic fluid, the combined hydraulic fluid flow being then utilized to pressurize, through another work exchange vessel, the solution feed flow to the reverse osmosis unit.

Pumping apparatus

In the reverse osmosis pumping system disclosed herein, a pair of work exchange vessels are located at two different heights. By means of a dense working fluid coupling one side of each of the vessels, an increased static head is maintained on one side of the apparatus relative to the static head corresponding to the fluid to be filtered which occupies the other side. The pumping system is operated alternately in low and high pressure phases. During the low pressure phase, the mean height of the dense work fluid is raised and the resultant stored energy is utilized to induce flow through a reverse osmosis membrane unit during the high pressure phase of operation. As it is important that a constant pressure and flow be maintained at the membrane chamber, multiple pumping systems are preferably provided, operating in phase alternation, so that the filter itself may be operated under relatively constant pressure.
