A session token can be requested to be sent to a first computing service from a second computing service, and a first computing service can receive the requested session token from the second computing service. Implementation of one such method, device and system includes inputting over an address bus a first portion of an address of a next row of memory cells to be activated. By choosing the first filtering element and the second filtering element substantially identical, it is possible to transform filtering characteristics of the first and second filtering element such that stop bands are substantially transformed into an effective pass band, and vice versa. Some of the methods utilize a second-order mathematical model of the dynamics of the actuators.
