Abstract: An exceptional road-condition warning device, system and method for a vehicle are provided. The system includes an information processing device and a display device. The display device provides real-time and advance warning information to a driver of the vehicle. The system may notice the driver and passenger in advance to respond to an exceptional road condition before the vehicle approaches the occurring place of the road condition through a back-end cooperative self-learning mechanism. The back-end cooperative self-learning mechanism may collect the exceptional road conditions from different vehicles and update the database automatically to maintain the accuracy. The back-end cooperative self-learning mechanism further shares the information stored in the database with the databases installed in the vehicles by a bidirectional communication manner to update the information inside the database of the vehicles for the information processing device.

Abstract: An electric vehicle charging-control system includes a charge-monitoring device coupled with a battery system of an electric vehicle, a processor coupled with the charge-monitoring device, and a communication interface coupled with the processor. The charge-monitoring device may detect the charging conditions of an electricity charge provided from a charging device to the battery system for charging the battery system, and the processor may determine whether the charging conditions exceed a tolerance criteria associated with at least one of the charge-monitoring device, the battery system, and the electric vehicle. The communication interface may communicate to the charge-monitoring device, a charge-receiving device, and/or the charging device at least one of a charging instruction and a charging indication provided by the processor based on a determination of whether the charging conditions exceed the tolerance criteria.

Abstract: A method for grouping wireless devices and an apparatus thereof are provided. First, the feature values of a plurality of access points (APs) detected by a wireless device are received, wherein these APs are designated as a first set, and the feature values of the APs constitute a feature vector. A first grouping process is performed to the wireless device according to the first set, which allocates the wireless device to an appointed clustering factory. A second grouping process is performed to the wireless device according to the feature vector, which divides all of the wireless devices within the appointed clustering factory into a member group or a noise group. Eventually, the grouping result is transmitted to the wireless device.
