Abstract: An elevator system (20) includes a transceiver (22) that receives at least one wirelessly transmitted signal (24). In one example, a signaling device (26) includes a plurality of switches (28) that can be activated to provide a signal indicating a desired or intended destination. The signal also provides an indication of the individual from whom the signal is received. A system controller (30) responds to the signal by assigning an elevator car (32) to travel to the intended destination. When the elevator car (32) is situated to receive the individual, in the event that another wireless signal is received, the system provides at least one access feature including delaying closing an elevator car door or generating an audible sound to guide the individual to the car. In one example, the system maintains information regarding expected locations of individuals providing such signals to facilitate providing assistance to them for exiting a building, for example.

Abstract: A metal or mineral compound collector for use in a froth flotation process so as to recover one or more desired minerals or metals; the collector comprising a functional group attached to a carbon chain; the functional group being a nitrile and the said chain having (11) or more carbon atoms. In a further form there is provided a method of recovering a metal or mineral compound from an ore comprising the steps of: wet grinding the ore to a desired particle size; adding water chemicals such as frothers or slurry-modifiers to the ground ore so as to prepare a slurry; adding an effective proportion of a collector comprising a functional group which has a carbon chain with a nitrile attached, said chain having (11) or more carbon atoms; supplying a gas stream to the slurry so as to generate a froth; and recovering the desired metal, mineral and/or sulphide thereof in the froth.

Abstract: A method and system are provided in which average vehicle speeds of tolled and non-tolled road segments between two locations are monitored and saved for reference in providing dynamic adjustment of the toll amount to be charged for use of the tolled segment in order to insure an efficient use of the tolled segment and a determination of an appropriate toll amount to be charged drivers in the tolled segment in view of real time traffic conditions of the tolled and the non-tolled segment. The toll adjustments are determined based upon the difference between actual average speeds of the tolled segment and actual average speeds of the non-tolled segment such that the toll adjustments are dynamic and depend upon real time traffic conditions in both the tolled and non-tolled segments of the travel route.

Abstract: Systems, methods and media for collecting and using machine usage data and machine configuration data are disclosed. In one embodiment, a workbench computer collects historical machine usage data for at least one load test machine emulating a plurality of users to produce a database of historical machine usage data for the at least one machine.

Abstract: A dynamic ‘vehicle grid’ system provides the ability for drivers to be automatically warned to the conditions of other vehicles in the vicinity. In this grid system, a motor vehicle would be equipped with a transmitter, receiver, computer and a selection of sensors. Other adjacent vehicles are also contain the same of equipment for transmitting and receiving signals. When the sensors in a vehicle detect a change such as hard braking (rapid deceleration) or very slow speed (blockages), it automatically sends this information via the transmitter over a wireless communication channel to any other receivers in the vicinity.

Abstract: An elevator rescue system provides rescue signals from a remote control station. The rescue signals typically operate a release mechanism such as the brake to allow the elevator to move to an appropriate door zone. The rescue signals are preferably sent from a remote control station such as may typically monitor a number of elevators. Essentially, the rescue signal is initiated when the remote control station receives a signal from the elevator monitoring system that a particular elevator is likely to have trapped passengers. As an initial step, the remote control station ensures there is no safety reason not to move the elevator, and then remotely commands operation of an elevator component that allows the elevator cab to move.

Abstract: The roll comprises a rotatable arbor (1) with an annular sleeve (7) shrunk onto it. There are internal passages (25) in the sleeve for the flow of liquid coolant there along. The internal passages are in communication with ducts (19, 21) in the arbor and the liquid coolant passed along the passages from the ducts forms a thermal barrier in the sleeve between the outer periphery and the interface.

The rollers are horizontally and vertically offset with respect to one another. An adjustment screw is provided to pivot the two housing parts towards and away from one another whereby a fine adjustment of the spacing between the rollers can be achieved.
