Abstract:
A vehicle (15), such as a lorry or a bus, includes compressed air consuming devices (13) and a power driven compressor (10) to deliver compressed air to at least one storage tank (11, 12). A control device (14) controls the operation of the compressor so as to maintain the air pressure in the tank at a desired pressure level sufficient to operate the air consuming devices, such as a braking system and a suspension system, when needed. The air pressure is usually maintained substantially at a predetermined first elevated level or value. However, based on signals from position identification means (17, 18), such as a global navigation system or other external or internal position identification sources the control device controls the operation of the compressor (10) so as to change the pressure of the air in the storage tank (11,12) to a predetermined second elevated level or value substantially different from said first level or value in response to receiving from the position identification means an indication to the effect that the vehicle (15) is approaching or has arrived at one (16,19) of a plurality of predetermined positions and/or positions fulfilling predetermined criteria.
Abstract:
The present invention relates to an apparatus and a method for managing and audit-ing purchases in progress which are made by a number of individuals belonging to a liable organisation, such as employees making purchases in parallel on behalf of a company. The invention comprises a managing server, including a storage means and issuing means, a client terminal connected to a network for providing information to the storage means about purchasing rules for individuals purchasing on behalf of their organisation. The issuing means is adapted to generate a unique num-ber, the number being issued and distributed to a purchasing individual, in dependence on the purchasing rules and a first communication terminal operated by a provider is adapted to, in response to a purchase, provide information to the managing server relating to a purchase in progress. Moreover, the invention is characterised in that the server is adapted examine whether information provided is in accordance with the purchasing rules, as a result of which a notification is sent to the first communication terminal so as to validate the purchase.
