Abstract: A retrofit system for the monitoring of seatbelt status in mass transit vehicles is adapted for retrofitting in different existing vehicles and includes a plurality of non-contact position sensors each associated with the buckle and tongue of a seatbelt, and a seat pan upholstery module with a seat occupancy sensor fixed to its inner side. The sensor of the non-contact position sensors is adapted to be fixed to an external surface of the buckle housing. A monitoring unit is coupled to the non-contact position sensors and occupancy sensors and to a display of seatbelt status comprising an indication that, when each of the seats is occupied, whether the respective seatbelt is in the fastened positioned or a released position.

Abstract: Respective electric drive motors (13a, 13b) drive left and right drive wheels (10a, 10b) having friction brakes, including an electromechanical service brake (31a, 31b) and an auxiliary brake (32a, 32b) mechanically biasing them to a braked state. An elongate handlebar (16) for user control is mounted via a pair of force-sensing couplings (17a, 17b) including a resilient member (18) and a load sensor (19) sensing forces applied by a user to the handlebar and transmitting respective load signals. A controller (37) receives the load signals and controls a current applied to the electric drive motors (13a, 13b) so as to amplify the force sensed by the force-sensing couplings and to generate a torque proportional to a force applied by the user to the handlebar and to actuate an electric release actuator of the auxiliary brake (32a, 32b) when the force applied by the user to the handlebar exceeds a threshold.

Abstract: A computer-implemented method for training a natural language translation model. The computer-implemented method includes: processing one or more sets of electronic parallel documents to obtain a plurality of aligned parallel sentences; creating a first training set including a subset of the plurality of aligned parallel sentences; and training the natural language translation model in a first stage using the first training set. The computer-implemented method further includes: modifying the first training set based on translation errors detected after the first stage of training; creating a second training set based on the modified first training set and at least some of the plurality of aligned parallel sentences not in the first training set; and training the natural language translation model in a second stage using the second training set so as to improve translation performance of the natural language translation model.
