Some embodiments of the present disclosure include a handheld tool for removing debris from a crevice. The control circuitry is operative to direct one or more packets having a given packet flow identifier to the operational unit in a manner that maintains a desired function call sequencing over the one or more packets having the given packet flow identifier for one or more order-dependent processing tasks in the processor. With the disclosed structure, it is possible to improve the integration density of a semiconductor device, to increase the short channel effect, and to improve the control rate of the resistance, while using a simplified manufacturing process. A first partner can grasp the handles and position the platform in front or in back of a second partner and insert the phallic device into a body cavity of the second partner.
