A delay-locked loop has a counter that is incremented or decremented by the loop in the process of achieving lock. The column of contacts of the first and second microelectronic elements can be aligned with the respective first and second parts of the opening. The stylus further includes an inner body installed inside the chamber in a movable manner relative to a first direction for pressing the expansible structure when moving in the first direction so that the expansible structure expands in a second direction. Components of the sampled motion signals in each group above a selected frequency are combined to generate respective group motion signals. The method includes configuring a flow table of the ingress switch to forward the data packets to a header compressor module in the ingress switch, configuring the ingress switch to instantiate the header compressor module, and configuring a group table of the ingress switch to manage forwarding of the data packets toward the egress switch. All of the active elements, including the power switches, may be integrated into a monolithic silicon circuit.
