Abstract: The present invention is a method and system for collection of exhaust emissions installed in vehicles and disposal thereof, based on pollution conditions of the surrounding environment, said conditions identified either from sensors installed on the vehicles themselves, or by means of an external service, e.g. the Internet, cloud service, etc.

Abstract: The disclosure relates to a method (50) performed in a network node (3, 4, 5) for notifying a driver of a vehicle (7) about his or her driving. The method (50) comprises receiving (51) vehicle related information from a communication device (6) capable of receiving data from a data collector (8) of the vehicle (7); processing (52) the vehicle related information such as to establish a driving indicator of a driver of the vehicle (7) in relation to one or more other drivers; and transmitting (53) to the communication device (6) data indicating the driving indicator of the driver of the vehicle (7) in relation to other drivers. The disclosure also relates to a corresponding network node, computer program and computer program products. The disclosure further relates to a method in a communication device.

Abstract: A method and polling system (100) for supporting evaluation of a service. The polling system (100) first identifies (1:1) a user to whom the service has been delivered, and then polls (1:2) the user to provide an investment in the service such that the investment is correlated to the user's assessment of the service. When the investment is received (1:3) from the user, polling system (100) determines (1:4) a deviation of the investment from an average value of a distribution of investments received from other users, and also determines (1:5) a gain or loss relative the received investment based on the deviation. The polling system (100) further sends (1:6) an indication of the gain or loss to the user in response to the received investment.
