The methods and systems described herein provide for allocating a universal serial bus device to one of a trusted virtual machine and a non-trusted virtual machine. The transfer apparatus performs a predetermined image pickup in each processing unit with the CCD camera and the laser displacement measurement apparatus 62 to perform monitoring of a required place in the processing unit. A multi-threaded copying procedure is effectuated to copy the identified portion from the original location to the destination location, thus generating a copied portion of the simulation modeling file. The cabinet may additionally comprise a chute gate release responsive to the controller for controlling the chute gate and a chute gate sensor connected to the controller and responsive to the position of the chute gate. The restricting module sets a value related to an item so as to restrict reproduction of the first video data. The sensor includes a flexible, initially substantially planar web-like support structure which has an adhesive layer on an upper surface thereof and a loop fabric backing on a lower surface thereof, a light source and a photo-sensor are mounted to the adhesive layer and a compressible foam layer having apertures which overlie the light source and the photo-sensor is mounted to the adhesive layer.
