A toy comprising a housing, a turbine-generator, and a light source. Particularly, polymer beads are used to rear endoparasitoids in vitro. In response to communicating the serial number to the host controller, the ACM receives a calculated unique key from the host controller and compares the calculated unique key with a unique key stored in a microprocessor associated with the ACM. Thus comparative strengths of muscles on opposite sides of the person’s body can be accurately determined by measuring the isometric force exerted by corresponding muscles on each side. At least one of the computing modules has a sequence learner module configured to associate sequences of input data received by the computing module to a set of causes previously learned in the hierarchy.
