A toy shopping cart has a basket and seat that may be used for different functions and which are easily removed from and reattached to a frame of the shopping cart. Example embodiments provide a dynamic GPU allocation system, which enables the efficient allocation of physical GPU resources to one or more virtual machines. The test programs are downloaded from the server for execution by the computing devices coupled thereto, so that at different computing devices execute different test programs substantially simultaneously. In further aspects, the atomization means communicates with a nasal, ocular, oral or \u2018vicinity\u2019 adapter. Accordingly, it possible to decrease variations in the compliance of the recording head without depending only on the accuracy of finishing.
